could never have been a miner. I just wouldn’t have had the patience. I read the other day that the average time it takes to get all the permits you need for a new mine in the United States is seven to ten years. And the US is a mining friendly jurisdiction with well established permitting procedures. Mining companies must obtain approval from several levels of government and a multitude of different regulatory bodies. In some areas, agreements must be reached with first nations groups, too. As resources run out in traditional mining districts, so the industry’s geographical reach stretches into less well developed parts of the world, where mining regulations are just taking shape. I’ve been wondering whether this makes a miner’s life more difficult, or whether there may be advantages in being in on the ‘ground floor’ of a regulatory regime. CEO Mark Bristow has said that Barrick Gold would not be afraid of operating in risky countries or working on difficult projects, pledging to increase the company’s exposure to the Democratic Republic of Congo and develop copper and gold projects in South America. He’s already settled a dispute in

Tanzania where the relationship between former subsidiary Acacia Mining and the government had been festering for three years over an unpaid tax bill. In the establishment of their mining regulations and tax regimes, developing countries are looking to ensure they receive a fair return for the extraction of their precious resources. One of these is Papua New Guinea, where Bristow has had several meetings with Prime Minister James Marape. “The people of PNG have a right to benefit from these resources and the government is their steward,” said Bristow in August. “The mining companies invest the capital and provide the expertise that makes profitable resource development possible. This common cause calls for a productive, mutually rewarding partnership between the miners and their hosts. Barrick has successfully established and maintained such relationships at its operations worldwide.” Some of the new mining jurisdictions may be unpredictable and ‘risky’ after emerging from political turmoil including, in some cases, civil war, but in the absence of layer upon layer of regulatory hoops, you can still do a deal there. I wonder if that’s what appeals to Mark Bristow. World Mining Magazine www.ogsmag.com

value creation

019 has been an eventful year for Barrick Gold. The company began the year as the world’s largest gold producer, after acquiring Randgold Resources in an all-stock deal for $6.5 billion, producing a combined entity holding five of the world’s top ten tier one gold assets. Randgold added some geographical diversity to the Barrick portfolio. Established in 1995, the company commissioned the Morila Gold Mine in Mali in 2000, followed by the Loulo mine in 2005. Loulo-Gounkoto is now one of the world’s largest gold mining operations and one of the largest businesses in West Africa. Randgold’s other assets include the Tongon Mine in Côte d’Ivoire, Kibali Gold Mine in the Democratic Republic of Congo, Massawa in Senegal and Lumwana in Zambia. Barrick’s tenure in the No 1 position was brief, however, as it was announced in January 2019 that Newmont Mining Corporation had agreed to buy Goldcorp in a $10 billion deal that would see this resulting combined entity become the world’s largest gold producer. In February, Barrick livened up the BMO Global Metals and Mining Conference by launching a surprise bid for Newmont, proposing an all-share transaction valuing Newmont at $17 billion. New Barrick president and CEO Mark Bristow said a Barrick/ Newmont deal would be superior to Newmont’s proposed acquisition of Goldcorp, adding that he expected the proposed merger to unlock more than $7 billion in synergies, a major portion of which would be generated by combining the two companies’ highly complementary assets in Nevada, where Barrick has significant mineral resources and Newmont has processing plants and infrastructure. Newmont responded vigorously, rebuffing Barrick and sticking firmly to its guns in respect of its Goldcorp proposal. Barrick’s Mark Bristow and Newmont’s Gary Goldberg engaged in a brief war of words before finally agreeing simply to combine their interests in Nevada. In April, a mere four months after the initial proposal was made public, Newmont announced the successful

conclusion of the transaction combining Newmont Mining Corporation and Goldcorp Inc into Newmont Goldcorp. Then, on 1 July, Barrick and Newmont announced the completion of their joint venture (first announced in May) to combine their respective Nevada properties into Nevada Gold Mines LLC.

Nevada

Nevada Gold Mines is a classic case of the whole being more valuable than the sum of its parts, according to Barrick CEO Mark Bristow. “It will be one of the world’s greatest gold mining operations and will create sustainable, long-term value for all its stakeholders, not least the State and people of Nevada.” Nevada Gold Mines is operated

and 61.5% owned by Barrick, and 38.5% owned by Newmont Goldcorp. The new JV ranks as the largest gold producing complex in the world by a wide margin, with three of the world’s top 10 tier one gold assets (Barrick’s Cortez; the combination of Barrick’s Goldstrike and Newmont Goldcorp’s Carlin; and Barrick’s Turquoise Ridge with Newmont Goldcorp’s Twin Creeks. Construction of the third shaft at Turquoise Ridge, which has a hoisting capacity of 5,500 tonnes per day, continues to advance according to schedule and within budget, with efforts in 2019 focused on surface civil works and shaft sinking. Its assets in northeastern Nevada comprise 10 underground and 12 open pit mines, two autoclave facilities, two

roasting facilities, four oxide mills, a flotation plant and five heap leach facilities. In 2018 these operations produced a total of 4.1 million ounces of gold, approximately double that of the industry’s next largest gold mine (Muruntau in Uzbekistan). Identified synergies are expected to deliver up to $500 million per year over the first five years from 2020, stepping down over time after that. These will come mainly from integrated mine planning, optimized mining and processing, cost reductions and the combination of the adjacent Turquoise Ridge and Twin Creeks, which will be operated as a single mine. In September this year, Barrick reported a new discovery hole about two kilometres from the best ever

drilling intercept at its Fourmile project in Nevada and said this pointed to the delivery of at least one more Tier 1 gold mine through the combination of Fourmile with the nearby Goldrush development project. Mark Bristow said diligent exploration and detailed geological modelling had led to effective targeting at Fourmile. The intercept is of a new orebody a kilometre north of Fourmile which increases the strike length of the mineralized Goldrush-Fourmile trend to greater than six kilometres. Mineralization is open in all directions and significant resource growth is expected from continuing the step-out drilling programme. Nevada Gold Mines is targeting production of between 1.8 and 1.9

The successful 20 year partnership between the government of Mali and Randgold made the gold mining industry one of the key drivers of the country’s economy. Briefing local media on the Loulo-Gounkoto complex’s current performance in October this year, Barrick CEO Mark Bristow said the new company was committed to further investment in Mali. He said it was currently developing a new underground mine at Gounkoto, replenishing existing reserves through brownfields exploration, prospecting for another world-class discovery along the Mali/Senegal shear zone and undertaking mapping and research in the south of the country. Bristow noted that Barrick entered Mali through Randgold’s discovery and development of Morila, which laid the foundation for its mining industry as well as marking the first true partnership between a host country and investors in West Africa. At Morila, which is nearing closure, the company has invested in an Agripole which will provide a sustainable postmining micro-economy for the villages around the mine. At Loulo, it has established an agricultural college which this year produced 40 farming graduates

who have been deployed across 10 farms. Bristow said in the past quarter LouloGounkoto had again set production records and was on track to meet its production guidance of 690,000 ounces of gold for 2019. Successful exploration was replacing depleted reserves, ensuring that its remaining life exceeded 10 years. In the DRC, Barrick operates Kibali, which is a joint venture with AngloGold Ashanti and the Congolese parastatal SOKIMO. Kibali, ranked among the world’s Top 10 gold mines, made a strong start to 2019 after setting a new production record last year. In October it was announced that the underground operation had again set new mining and shaft production records in the third quarter to keep the Barrick Tier 1 gold mine on track to meet or beat its guidance of 750,000 ounces for the year. Throughput and recovery for the quarter were at or above the nameplate level. Briefing local media, Bristow said Kibali – already a world leader in automation – was taking this to the next level with the commissioning of a Newtrax system which would provide real-time data collection, enhance predictive maintenance, track and manage the fleet, and implement a digital safety system with personnel tracking. The mine is also working towards a proof of concept of a highly advanced system which will allow manned and unmanned operations in the same area. World Mining Magazine www.ogsmag.com

barrick gold value creation In Zambia, the Lumwana copper mine is a conventional open pit (truck and shovel) operation. It’s located about 100 kilometres west of Solwezi in Zambia’s Copperbelt—one of the most prospective copper regions in the world. Lumwana ore, which is predominantly sulphide, is treated through a conventional sulphide flotation plant, producing copper concentrate. The mine produced 224 million pounds of copper in 2018. Barrick also owns Acacia Mining in Tanzania, where the relationship between the previous owners and the Government of Tanzania (GoT) deteriorated over recent years. Barrick recently bought out the minority interests to enable it to negotiate with the GoT independently. An agreement has now been reached which includes the payment of $300 million to the GoT to settle all outstanding tax and other disputes, the lifting of the concentrate export ban, the sharing of future economic benefits from the mines on a 50/50 basis and the establishment of a unique, Africafocused international dispute resolution framework. A new operating company called Twiga Minerals Corporation (Twiga) has been formed to manage the Bulyanhulu, North Mara and Buzwagi mines. (Twiga is the Swahili word for giraffe, Tanzania’s national symbol.) “Rebuilding these operations after three years of value destruction will require a lot of work,” said Mark Bristow, “but the progress we’ve already made will be greatly accelerated by this agreement. Twiga, which will give the government full visibility of and participation in operating decisions made for and by the mines, represents our new partnership not only in spirit but also in practice.”

South America

Barrick’s approach to South America has been somewhat mixed in the past, to the extent that new CEO Mark Bristow saw fit to renew the company’s commitment to the region in July this year. Speaking at a meeting with local community leaders and media in Argentina, Bristow said the company’s assets in the region were a major part of its global portfolio and there was enormous potential for new discoveries

capable of amplifying Barrick’s ability to create real value for all its stakeholders. “Barrick holds a highly prospective land package, with mining rights covering some 34,000 hectares, in the El Indio gold belt. This legendary gold province, which spans Argentina, Chile and Peru, has already yielded five significant discoveries and we believe its mineral wealth still offers a very substantial upside,” he said. “We have a new regional exploration strategy that is being implemented by a best-in-class team drawn from the merged Barrick and Randgold. In Argentina alone, we plan to invest more than $30 million in exploration over the next two years.” At Veladero in Argentina, Bristow said, work to reclaim its full potential and extend its life was already showing results, with the mine increasing production by 26,000 ounces in the second quarter of this year. He noted that over the past 14 years Veladero had contributed some $8.9 billion to the Argentine economy through taxes, royalties, salaries and payments to local suppliers. In addition, the mine has established a new trust fund that could deliver more than $70 million in community infrastructure between 2020 and 2028, depending on production. In Chile, the Norte Abierto and Alturas projects are progressing, but the giant Pascua Lama project on the border with

Argentina has been closed since 2013 because of environmental difficulties. The current focus there is on going back to basics to review the original project’s parameters and redefine its future potential. In Peru the Lagunas Norte mine is being placed on care and maintenance while the team assesses the sulphide resource potential, and at Pierina closure planning is continuing. Bristow said Barrick acknowledged that there were legacy challenges in each of these countries. It was engaging with their governments and communities to resolve these and to build productive new partnerships with its hosts to ensure that the new value that is created benefits all stakeholders. “We are an organization that has grown out of pioneering exploration, discoveries and development. Given our established presence here, our local geological knowledge and exploration skills, we are committed to becoming a leader in the region,” he said. In the Dominican Republic, by contrast, the expansion of Pueblo Viejo is expected to maintain the mine’s Tier One status for years to come. Plans include an expansion of the mine’s processing plant and tailings capacity with an estimated initial capital investment of more than a billion dollars and the potential to extend the life of the mine into the 2030s and beyond. Barrick expects to complete a feasibility study World Mining Magazine www.ogsmag.com

for the expansion project during 2020. The proposed capital investment would more than double the contribution the mine has already made to the Dominican Republic.

Rest of the world

The Jabal Sayid copper operation is located 350 kilometres north-east of Jeddah in the Kingdom of Saudi Arabia. It’s a 50/50 joint venture operation with Ma’aden. The first shipment of copper concentrate occurred in December 2015, and the mine commenced commercial production in July 2016. It produced 55 million pounds of copper in 2018, and forecasts 45 – 60 million pounds this year. In Papua New Guinea, the Porgera Joint Venture is an open pit and underground gold mine at an altitude of 2,200-2,600 meters in the Enga Province, about 600 kilometres northwest of Port Moresby. Barrick and Zijin Mining Group each own 47.5 per cent of

the operation, with the remaining 5 per cent interest held by Mineral Resources Enga. Porgera’s special mining lease expired in August 2019 and the government is considering an application for a 20-year extension. Barrick CEO Mark Bristow said Prime Minister Marape’s view that PNG should receive a better share of the benefits generated by the development of its mineral resources was in line with Barrick’s own commitment to ensuring that the value created by its operations should reward all its stakeholders, especially its host governments and communities. “The people of PNG have a right to benefit from these resources and the government is their steward,” he said. “The mining companies invest the capital and provide the expertise that makes profitable resource development possible. This common cause calls for a productive, mutually rewarding partnership between the

miners and their hosts. Barrick has successfully established and maintained such relationships at its operations worldwide.” Barrick has recently announced the sale of its share in a 50/50 joint venture with Newmont Goldcorp in Australia, the Kalgoorlie mine, in Western Australia. The Kalgoorlie operation consists primarily of the Super Pit openpit mine, located along the Golden Mile ore bodies which were previously mined from underground. The mine is located adjacent to the town of Kalgoorlie, approximately 350 miles east of Perth, Western Australia. Kalgoorlie is an open-pit, truck-and-loader operation. The Hemlo operation in Canada has produced more than 21 million ounces of gold, and has been operating continuously for over 30 years. It consists of the Williams mine, an underground and open pit operation located about 350 kilometres east of Thunder Bay, Ontario.

At the end of October this year Barrick announced that operations at Hemlo are being modernized and refocused to secure the mine’s continued viability. Several programs have been introduced to improve its performance and the next step will be to phase out the open pit operation and move to an underground contract mining model. The objective is to upgrade Hemlo to a Barrick Tier 2 asset and extend its Life of Mine well into the future. “By repositioning Hemlo as a smaller but more profitable business, we are ensuring that it will continue to deliver value to its community, employees and other stakeholders for years to come,” said Catherine Raw, Barrick’s chief operating officer for North America. “A longer sustainable mine life will create longer-term employment opportunities and longer-term benefit sharing with the local community and economy,” she said. “Because of the move to contract

mining and the introduction of new technology, we are inviting the majority of employees working underground to participate in a voluntary separation program. We have already met with these employees to inform them about the program and to assure them that they will be treated fairly and with respect for their service to the mine.” On becoming chief executive of Barrick Gold Mark Bristow pledged to make Barrick more agile with fewer layers of management, by cutting the number of workers at head office in Toronto and reversing plans to hire big data analysts and coders, preferring to hand control of operations to local mine sites. “What we want to do is make sure we implement that at the site,” he said. “We don’t want IT to wag the dog, we want it to be an integral part of everyday operations. The manager of the mine should get the data first.” Bristow also said that Barrick would

not be afraid of operating in risky countries or working on difficult projects. He wants to increase its exposure to the Democratic Republic of Congo, he said, and develop copper and gold projects in South America. “Our aim is to make the Barrick brand synonymous with value creation,” he said. “That value will be generated by our existing Top Tier operational base of long-life mines, located within worldclass geological provinces and run by management teams that can unlock and bring to account opportunities where others have failed,” he added. “But there is also a lot more to be done, notably in Latin America and Tanzania, and you can be sure that we remain unrelenting in our quest to be the industry leader in value creation and delivery.”

T

he Sleipner transport system has been used to transport excavators, the giants of mining sites, for more than 20 years. More than 200 devices at over one hundred mines around the world use “Sleipners” to move crawler machines quickly. Ossi Kortesalmi, the man behind the revolutionary innovation, reveals how it all started with an issue detected in the daily routine of a mine and how the internationally recognized company has continued its pioneering work around the world.

Ossi Kortesalmi, the innovator of the Sleipner system

The Sleipner transport system, designed to make transporting crawler excavators easier, was created in 1996, when Ossi Kortesalmi was operating an excavator at the Kemi chrome mine in Finland. Kortesalmi was frustrated at the amount of useful working time wasted on transporting the crawler slowly and uncomfortably on its tracks from one site to another over large distances. On a long night shift, he began to develop an idea that would revolutionize the transportation of heavy excavators. “I was waiting for some trucks to arrive when I came up with the initial drawing of a solution that would allow crawler excavators to be transported quickly and smoothly to their destinations on rubber wheels. I presented my idea to Ari Mäntylä, the head of the chrome mine, who right away was impressed with my solution. The drawings were used to create a platform on wheels, upon which an excavator was placed for transportation. The bucket of the excavator was placed on the back of an accompanying truck, and the crawler excavator was moved in quick fashion.”

The following trials proved the concept. The efficiency of operations at the chrome mine increased as the time spent transporting excavators decreased by as much as 80%. The successful pilot trial encouraged Kortesalmi to apply for a patent for his innovation and to find a company to develop it further.

A solution to a real problem

Sleipner’s solution was an answer to a real problem observed in actual work. Far too often, crawlers are transported on their tracks at mines. The transportation of a single excavator does not have a significant impact on the expenses of a company, but if there are many weekly transportations that require time and wear out the excavator, the amount of time wasted on transportation is multiplied. The Sleipner transport system allows for excavators to be moved from one location to another quickly in normal mine conditions, saving more time for productive work. “The first Sleipner prototype was put into operation in 1996. Sturdy Sleipners withstand the test of time, as demonstrated by the fact the pilot version is still being used. Since then, the Sleipner transport system has been developed and scaled for excavators of different sizes, from 30 metric ton excavators to giants weighing up to 570 metric tons.”

The pioneer doubles its efforts

Although the need for smooth transport operations at mines is self-evident, Sleipner did not take over the world in a day. Replacing old methods with a more efficient one required intensive legwork

from the inventors to introduce the concept to every corner of the market. “Initially, the new solution aroused skepticism. No one was willing to be the first one to test a new solution. Most meetings included explaining how safe the Sleipner transport system is in the challenging conditions of mines. The experiences of our customers from around the world were in our favor.” Today, Sleipner Finland has customers on six continents. Some of the bestknown mining industry giants around the world have begun to use the Sleipner system.

The best innovation is simple and durable

The Sleipner system invented by Kortesalmi is, despite its creativity, a very simple device. It consists of two pairs of massive axles that support a ramp upon which the excavator’s tracks are placed. The mechanical Sleipner system can weigh up to 85 metric tons and it is extremely durable and safe. Supported by the wheels of the transport system and the mine or dump truck acting as the tractor unit of the excavator, the excavator can be transported at the speed of 10–15 kilometers per hour instead of the usual 2 kilometers per hour on tracks. “My original motivation was to create

a solution that can withstand the test of time and extreme stress, and we have managed to do so. The Sleipner transport system only needs minimal maintenance. Nevertheless, the systems alone cannot solve all problems, which is why we provide all our customers with personal training in the use of the Sleipner system. In the end, people are responsible for the safe and efficient use of the equipment.” Sleipner’s range of products has extended from the transportation of excavators to complete mine-site mobility solutions. In addition to transporting excavators, Sleipner’s DBseries facilitates the safe and efficient transportation of bulldozers, drills and other machines on tracks. More information is available in following issues. Sleipner Finland Oy is a supplier of mining industry equipmentestablished in 2011, and its history dates back to 1996. Sleipner provides companies in the mining industry with tracked loader transport systems devices that can be used to transport heavy machinery up to 570 metric tons in weight. Rio Tinto, BHP, Barrick, Anglo American are all major global mining companies that use Sleipner’s solutions. World Mining Magazine www.ogsmag.com

Illegal blockade lifted at Peñasquito Mine in Mexico

N

ewmont Goldcorp has confirmed that the illegal blockade of the Peñasquito mine in Mexico has been lifted. The company continues to work closely with the federal and state governments towards a sustainable, long-term solution, and lifting of the blockade paves the way for the government-sponsored dialogue to resume.

To protect people, assets and the longterm viability of the mine, operations at Peñasquito have been suspended since the illegal blockade began on 14 September. Operations remain temporarily suspended pending further evaluation of the situation and assurances that the blockade will not be allowed to resume.

The illegal blockade impacted Peñasquito’s third quarter production by approximately 11,000 gold ounces, 1.7 million silver ounces, 13.7 million pounds of lead and 22.8 million pounds of zinc, and is expected to impact the company’s full-year results for the operation.

recoveries during ramp-up have been above expectations, the Gruyere Joint Venture now anticipates gold production for calendar 2019 to be at the upper end of guidance of 75,000 to 100,000 ounces. Gruyere is a global Tier 1 gold mine

with a long operating life and forecast high margins. Life-of-mine average annual production is forecast at approximately 300,000 ounces per annum at average all-in sustaining cost (AISC) over a 12-year life of approximately A$1,025 per ounce.

Largo Resources announces record V2O5 production in Q3 2019 “Operations at the L Maracás Menchen Positive update from RNC Minerals

R

NC Minerals is targeting production for the six-month period ending 31 December 2019 of between 42,000 to 49,000 ounces of gold at an average all-in-sustainingcost of US$1,150 to $1,250 per ounce. RNC is currently focused on the integration of its Beta Hunt Gold Mine with its recently acquired Higginsville Gold Operation in Western Australia. “Our focus moving forward remains on delivering on our production guidance, while continuing to reduce costs through all levels of our business,” said Paul Andre Huet, Chairman & CEO. “Third quarter 2019 production of 24,216 ounces is an excellent result for RNC’s first full quarter of production since acquiring the Higginsville Gold Operation (HGO). We look forward to continuing the momentum into the fourth quarter and building on what has already been a great start. At Baloo, we are encouraged by ongoing exploration results to the north and additional results to the east of the current pit, both of which have the potential to extend the current open pit. A comprehensive review of the large existing historical HGO resource base has commenced. To date, the review has identified a number of potential areas for follow up drilling which have the potential to provide additional long-term feed to the HGO processing plant.  At Beta Hunt, work on the new Beta Hunt mine reserve remains on track to be completed in the fourth quarter of 2019. This work has also identified a number of bulk mining opportunities which have the potential to improve productivity and lower costs.

argo Resources has announced third quarter 2019 production results from its Maracás Menchen Mine in Brazil, highlighted by a new quarterly production record of 2,952 tonnes of vanadium pentoxide, at an average global recovery rate of 78.1%. This represents an increase of 17% over Q2 2019 and a 15% increase over Q3 2018.

Production in July was 1,042 tonnes, a new monthly V2O5 production record for the company, as a consequence of the start-up of the second deammoniator as

part of the expansion project in addition to the consumption of intermediary stockpiles. Production of 975 tonnes of V2O5 in August was slightly above budget and was aligned with the ramp-up schedule for the expansion project. Production of 935 tonnes of V2O5 in September was impacted by leaching area availability. The company’s expansion project is in the final stages of commissioning following the start-up of the new ball mill in September and is expected to reach the new nameplate capacity of 1,000 tonnes of V2O5 in October. “Operations at the Maracás Menchen

Mine continued to produce strong results in Q3 2019 following increased production as result of the expansion project”

Mine continued to produce strong results in Q3 2019 following increased production as result of the expansion project,” said Paulo Misk, president and chief executive officer of Largo. “Total year-to-date V2O5 production is 7,566 tonnes and the company maintains its overall 2019 production guidance range of 10,000 to 11,000 tonnes for the year.” Largo is a Toronto-based strategic mineral company focused on the production of vanadium flake, high purity vanadium flake and high purity vanadium powder at the Maracás Menchen Mine located in Bahia State, Brazil.

Glencore announces permanent closure of Brunswick Smelter Facility

G

lencore Canada has announced the permanent closure of the Brunswick Lead Smelter in Belledune, New Brunswick. The smelter opened in 1966 and employs approximately 420 people. The decommissioning process will begin immediately and the smelter will cease all operations by the end of the year. “The decision to cease lead smelting operations at our Brunswick Smelter was a very difficult one,” said Chris Eskdale, Glencore’s Head Zinc & Lead Assets. “Despite years of efforts by committed employees and a strong management team, the smelter has been uneconomic since the closure of the Brunswick Mine in 2013.” He said the company had thoroughly assessed all its options but had come to the unavoidable conclusion that the smelter was simply not sustainable. After thanking all Brunswick smelter employees, past and present, he said that Glencore was committed to

working closely with employees, unions and other community stakeholders to mitigate the impact as much as possible. The company will provide pension, severance and outplacement support services for all employees as part of closure settlements to be agreed on and will meet with union leaders to discuss an orderly transition to closure. A small number of employees will be retained for on-site monitoring, water treatment and closure projects in the months ahead, and the company will seek potential relocation opportunities at its mining and metallurgical operations in other provinces and countries. It also said it would work with local stakeholders and agencies to identify opportunities for regional economic development and meet all of its closure obligations with respect to environmental and other regulatory requirements.

Inomin acquires nickel properties in British Columbia I

nomin Mines has acquired the Beaver and Lynx properties prospective for large, bulk-tonnage sulphide nickel deposits, in the Cariboo region of southcentral British Columbia, not far from the Gibraltar mine, the second largest open-pit copper mine in Canada. Widespread nickel found at both properties indicates the region could host significant nickel deposits with credits for cobalt and other minerals. Inomin acquired the properties through staking to hold a 100 per cent interest. The Beaver nickel-cobalt property is an advanced exploration property 15 kilometres east of the Gibraltar copper mine, with excellent infrastructure including paved and forestry service roads allowing easy access to all parts of the property. Previous exploration in the area initially targeted gold, which was found in select areas, whereas nickel sulphide and cobalt were discovered in all areas drill tested. As the Beaver property is near the Gibraltar mine and other porphyry deposits, the district is geological conducive for hosting substantial polymetallic deposits. The Lynx nickel property, just 11 kilometres south of Beaver, is in a similar but larger nickel geological environment to Beaver, with extensive nickel occurrences in outcroppings.

RGS (regional stream sediment) data collected by the Province of British Columbia illustrates the existence of a large 10 x 5 kilometre nickel anomaly on the Lynx property. Past exploration at the Beaver and Lynx properties occurred when nickel prices were relatively low – around US$4.00/ lb. As the past ownership group turned their attention to their new gold discovery elsewhere in the region, no further work was done at the properties. The current nickel market is more robust, fuelled by growth in global stainless steel and rapidly growing battery markets for phones, laptops and especially electric vehicle (EVs) batteries.

BHP funds Samarco restart preparation

F

our years after the failure of the Fundão dam on 5 November 2015, BHP has taken a step towards restarting operations at Samarco Mineração in Minas Gerais, Brazil. Samarco is a 50/50 joint venture with Brazilian mining company Vale, and BHP has approved US$44 million for its share of funding for work related to the restart of one concentrator. The funding will enable the construction of a filtration plant over the next 12 months and the commencement of operational

Whereas steel relies primarily on nickel pig iron (class 2) nickel, EV batteries typically use higher purity sulphide (class 1) nickel. The nickel market is expected to be largely in deficit during this period of highgrowth demand. John Gomez President & CEO of Inomin Mines, says, “The Beaver and Lynx properties provide the company with two large nickel sulphide exploration projects in our backyard. Given the properties’ favourable geologic characteristics and the excellent infrastructure, the region could develop into a significant new nickel camp.”

readiness activities for a restart. On Friday 25 October 2019 the Mining Activities Chamber of the State Council for Environmental Policy in Minas Gerais, granted the Corrective Operating Licence for Samarco’s operating activities at its Germano Complex. Samarco has now obtained all environmental licenses required to progress towards operational restart. Restart can occur when the filtration system is complete and Samarco has met all necessary safety requirements, and will be subject to final approval by Samarco’s shareholders.

Canada Cobalt pours first silver bars

Commercial production achieved at Quecher Main

N

C

anada Cobalt Works has successfully poured its first silver in a proof of concept test at its 100 per cent owned Castle silver-cobalt mine in northern Ontario, Canada. The pilot plant separated leaf silver and created silver gravity concentrate from mineralized Castle waste material. The concentrate and leaf silver were then smelted in the bullion furnace at PolyMet Labs in the town of Cobalt, just a one-hour drive from the Castle mine, to produce three silver bars totalling 300 ounces. Through its proprietary and environmentally friendly Re-2OX Process, and further demonstrating proof of concept, Canada Cobalt also used the same waste material to separately recover cobalt and produce a cobalt sulphate at SGS Lakefield. The company has also announced that multi-directional diamond drilling on the first level of the mine is expanding the footprint of cobalt, nickel and silver mineralization near the adit entrance, where drilling last year returned high grades. A total of 13 drill holes have already been completed in the adit entrance area with visible mineralization noted in a majority of them. Cobalt grades intersected in the Castle mine, previously exploited only for its native silver, are considered very high in a global context. Canada Cobalt is now permitted to carry out underground blasting at Castle which will greatly assist the company’s exploration efforts

during this new phase of drilling. As previously announced, Canada Cobalt has agreed to acquire privatelyheld PolyMet Resources Inc, which owns the only facility in the northern Ontario silver-cobalt district that combines bullion pouring, bulk sampling, commercial assaying and e-waste processing - four key profit centres specializing in high-grade

mineralization. This facility would be the new headquarters for Canada Cobalt and its Re-2OX Process. The acquisition will put Castle Cobalt in a position to become a vertically integrated North American leader in cobalt extraction and recovery, while it also exploits a powerful new silver-gold market cycle.

Canada Cobalt is now permitted to carry out underground blasting at Castle which will greatly assist the company’s exploration efforts during this new phase of drilling.

ewmont Goldcorp has achieved commercial production at the Quecher Main project at Yanacocha in Peru, safely, ahead of schedule and under budget. The full project, including future leach pad expansions, is expected to be completed for approximately $275 million of development capital (below the company’s initial estimate. Quecher Main extends the life of the Yanacocha operation to 2027, contributing average annual gold production of approximately 200,000 ounces from 2020 through 2024 at all-in sustaining costs between $900 and $1,000. The project is expected to generate an internal rate of return of approximately 15 per cent at a $1,200 gold price.

“Quecher Main is the fourth profitable project we’ve brought into operation on four different continents this year, on schedule and within budget,” said Tom Palmer, president and chief executive officer. “The project takes advantage of Yanacocha’s existing infrastructure to add profitable production from remaining oxide ores while also serving as a bridge to future growth opportunities, including Yanacocha’s extensive sulfide deposits.” Yanacocha began commercial production in 1993 and has since produced more than 38 million ounces of gold from open pit oxide and transitional ores. The operation is a joint venture between Newmont Goldcorp (51.35%), Minas Buenaventura (43.65%) and Sumitomo Corporation (5%). World Mining Magazine www.ogsmag.com

Glencore’s IsaMill technology helps solve complex challenges in Russian mine G

lencore Technology and Hatch are helping Ozernoye to develop a mining operation in Buryatia, Russia to produce zinc and lead concentrates. The company is preparing the area for the Ozernoye polymetallic mine and concentrator in the Yeravninsky region, 60km from the Sosnovo-Ozerskoye regional centre. Glencore Technology’s Adam Price said the ore mineralogy at the site was remarkably similar to Glencore’s McArthur River project which originally brought about the need to create the IsaMill ultrafine grinding technology which turns 25 this year. “Ozernoye’s mineralogy is complex, and

it’s going to need the right flowsheet to improve the recovery and concentrate quality and therefore ensure the economic viability of the project,” said Price. He said the fine-grained lead zinc ore at the Australian operation made for an obvious benchmark. This year, Ozernoye has been embarking on mining, capital works and construction of infrastructure facilities: tailing dam, water distribution system, pit stripping, and camp expansion. Major construction of the plant’s facilities is planned for 2020-2022 and the company plans to reach design capacity of 8Mtpa in 2024. The original 1994 IsaMills are still

operating at McArthur River Mine, but the IsaMill technology has been refined to occupy a small footprint, very high availability and significant energy efficiency.

oneta Porcupine Mines has commenced drilling on the Golden Highway Project, 70 miles east of Timmins, Ontario. The company is sole owner of six core gold projects along the Destor-Porcupine Fault Zone in the Timmins Gold Camp. “We are encouraged by our enhanced understanding of the geology of the Windjammer South and 55 deposits where we have identified the potential to expand the current resources,” said Gary O’Connor, CEO & chief

geologist. The new drill program will test the resource expansion potential at 55 and Windjammer South which occur adjacent to the South West, where we are currently updating the resource based on our 2019 drill program. “The current drill program will also test the Westaway and Halfway targets where mineralization was intersected historically and will target the area between West Block and Westaway which remains open. We look forward

to drilling the expansion potential of our resources and to test new areas of mineralization. In addition, we will be releasing the updated South West resource estimate by the end of November.” The current planned drill program consists of an initial 10,000m to test the new resource potential and occurrence of mineralization at new targets, with additional drilling planned as warranted.

vega using technology to automate mining processes Mining has come a long way since people first figured out they could unearth valuable minerals and materials from underground. Historians have even found evidence of prehistoric humans using flint to dig and scrape at the earth to extract pebbles and minerals. In the early days, mining was labor intensive and dangerous.

T

oday’s mines use technology to automate many processes, and consequently, this allows mines to run more efficiently, use less energy and water, and operate more safely. VEGA, a worldwide level and pressure measurement company, has been around for a little more than 60 years, and in that small span of time, the company’s innovative instrumentation has played an integral part in revolutionizing how both large and small mining companies operate today. VEGA specializes in a handful of technologies to measure continuous level, point level, pressure, density, and even the mass flow of solids. Measuring variables throughout the mining process allows operations to improve efficiency and avoid upsets or unexpected downtime that could increase costs or decrease the amount of throughput. From conveyors and crushers to the end product, monitoring certain process variables gives operators and plant managers a window into what’s happening each step of the way and make improvements to increase total throughput. Maintaining a maximum throughput also allows mining operations to get the most out of their energy usage – easily the most expensive cost at any mine. This can be minimized and waste can be eliminated by tracking process measurements and making corrections before a problem occurs. The same can be said about another limited resource, water. Water is vital to processing and moving minerals in any mining operation, and many mines are located in deserts where water is scarce. Conserving this valuable resource and minimizing its use through proper controls affects the bottom line and shrinks the mine’s environmental footprint. Sensors and automation have also improved the safety conditions. Every mine embracing technology and a new way of doing things has seen better safety records. For instance, where people once had to climb a tall silo or tank to manually make a level measurement many times a day or every week, a level measurement sensor is installed once. Now the previous fall risk is permanently eliminated, and someone can see the level at all times from the safety of a control room. While the technology and the processes used in mining may have changed, one thing hasn’t changed – mines are unforgiving, dirty environments. VEGA designs and manufactures their instrumentation with these conditions in mind. Every sensor, controller, and component is put through vigorous testing in simulated environments to ensure they’re prepared for real-world applications. VEGA sensors are made with aluminum and stainless steel housings, and most sensors can withstand the extreme process pressures and temperatures found in mines around the world. The technologies VEGA uses in the mining industry vary, but perceptive eyes will notice three main technologies over and over again: radar, pressure, and radiometric. Each of these can be found in a number of applications within a single mining operation anywhere in the world – whether its precious metals, minerals, or aggregates.

The 80 GHz VEGAPULS 64 radar sensor continues to accurately track level despite heavy buildup, turbulence, and steam

vega using technology to automate mining processes Radar: VEGA’s specialty

Much of VEGA’s reputation around the world is built around their worldclass radars for level measurement. To many customers, VEGA is known as the radar company. VEGA solidified that status when they introduced the latest breakthrough in radar technology: 80 GHz frequency. The latest generation of high frequency radars delivers an enhanced focus and a higher sensitivity, which provides a higher measurement certainty over the entire measurement range. The new technology is allowing radars to make level measurements in applications that were previously impossible. The VEGAPULS 64 and the VEGAPULS 69 are VEGA’s 80 GHz radar sensors. The VEGAPULS 64 measures continuous liquid level, and the VEGAPULS 69 is specifically built for measuring the continuous level of bulk solids ranging in size from large rocks and small boulders to fine powders and ash. This technology makes choosing a level measurement sensor easier than it’s ever been. The VEGAPULS 64 can measure the level of liquids and slurries, and the VEGAPULS 69 can track the level of any bulk solid. As raw materials mix with liquid for processing, it forms a sticky, muddy mixture, and it can be difficult to track the level inside the tank or vessel. One of the largest platinum mines in the world understands this firsthand. In the final concentrate collection tank, water and aeration are used to separate the valuable platinum from the rest of the materials being extracted. The platinumrich mud sticks to everything it touches, including any level measurement instrumentation, which made it difficult to provide a reliable and accurate measurement. Other technologies worked, but those instruments required constant maintenance, which resulted in additional downtime. Once the platinum mine installed a VEGAPULS 64, maintenance and downtime for instrumentation became a thing of the past. The new radar sensor uses a special algorithm built within the electronics to ignore any buildup on the antennae while still being able to reliably make this critical measurement. With a consistent measurement, the risk of overflows and resultant process

The 80 GHz VEGAPULS 69 can accurately track the level in the crusher from a distance because of the narrow beam angle shutdowns were eliminated. Now the process can continue operating efficiently with less downtime and a higher throughput. In the early stages of any mining process, crushers are used to change the size of larger rocks into smaller rocks, reducing them to a workable size. Measuring level in this application is a particularly difficult one for most technologies because of falling materials, dust, debris, loud noises, and moving parts and internal structures within the crusher itself. All of these factors can interfere with a level measurement inside a crusher, which can affect how efficiently the crusher operates. One of the largest aggregate producers in the United States knows all too well the challenges of effectively running a

crusher. At just one of their facilities, operators had been running all fifteen crushers at a fraction of their potential because they didn’t have a reliably accurate measurement. Once they replaced the old measurement technology they had been using for 80 GHz VEGAPULS 69 radar sensors, they realized the full capability of their crushers – increasing throughput by 50 percent per vessel. A small investment in a superior technological solution was able to exponentially increase the bottom line at a single facility. Every mining facility keeps a stock of dry products in storage silos, and monitoring the level in these silos is of the utmost importance for inventory and process control. However, it can be dangerous to send someone to the top of World Mining Magazine www.ogsmag.com

vega using technology to automate mining processes the silo on a regular basis. Fortunately, 80 GHz radar does just as well with fine powders as it does with the larger rocks found in the crusher. A South African gold mine keeps cement on site for backfill and support in the mine. Cement is a fine powder, and dust clouds form and linger for a long time during filling and emptying cycles. The thick dust cloud interferes with level measurements using other technologies, but the exceptional focus and superior sensitivity of the VEGAPULS 69 provide an accurate and reliable measurement, even during filling and emptying. Mines quickly adopted 80 GHz radar because they immediately saw the benefits of the new technology: making measurements despite buildup and the ability to “ignore” any dust floating in the air. The higher frequency also provides a more focused signal, so operators can aim the radar to avoid internal structures that would otherwise disrupt the signal and cause a measurement error. Plus, radar sensors are immune to acoustical noises, unlike other non-contact level measurement technologies. The VEGAPULS 64 and the VEGAPULS 69 provide accurate and reliable measurements for notoriously difficult applications.

replacement of pressure sensors, VEGA turned to ceramic measuring cells for many mining applications. Ceramic is abrasion-resistant by nature. The material’s tight, dense matrix makes a ceramic diaphragm ten times harder than one made of stainless steel. This extra strength makes pressure sensors with ceramic cells better-equipped to withstand the harsh environments found in so many applications at a mining operation. Ceramic cells continue to perform reliably long after their metallic counterparts have been replaced over and over.

understands differential pressure and how it works. VEGA rebooted this concept with electronic differential pressure, using two separate pressure transmitters connected by an electrical cable. This setup opens up a new world of measurement possibilities. Electronic differential pressure uses two VEGABAR sensors to provide a number of different outputs, including differential pressure, level, interface, flow rates in a pipe, the changing density of a fluid, and density-compensated level. Density-compensated level uses two independent VEGABAR sensors

Manufacturing pressure sensors that last

A single pressure transmitter is most commonly used for one of two applications: process pressure and hydrostatic pressure. Process pressure simply measures the pressure of liquids, gases, and vapors in a vessel or inside a pipe or tube, like those transporting a slurry from one process to the next. Hydrostatic pressure takes an additional step and uses a known specific gravity or density measurement of a product to calculate the level inside a tank or vessel. Hydrostatic pressure can be especially helpful for monitoring inventory of liquid additives needed for processing. In the same way hydrostatic pressure takes a pressure measurement one step further, VEGA has made leaps and bounds using two pressure transmitters and electronic differential pressure.

installed at a fixed distance apart to calculate liquid level in applications where the process medium is constantly changing density. For example, two independent VEGABAR 86 submersible pressure transmitters installed at a fixed distance apart and always covered by the process medium can continuously calculate density using the two pressure measurements and the known distance between the transmitters. Those variables and the current density are then applied to the lowest sensor, which calculates the overall hydrostatic level. This never ending calculation loop provides continuous overall level feedback on a process with constantly changing density. VEGA has applied this technology to froth flotation cells at precious metals mines around the world. Flotation cells separate fine materials from a slurry by adding chemicals and aeration. The desired particles adhere to the air bubbles rising from the bottom to

Pressure is a widely used measurement for process control in a number of industries, and mining is no exception. By comparison, pressure is old technology, but that just means it’s had more time to innovate and improve. The VEGABAR series of pressure transmitters from VEGA is proof of this innovation. Today’s pressure transmitters are more durable, which allows them to last longer in harsh environments, and they’re more versatile, with the ability to use a pressure measurement to output more variables than ever before. Pressure transmitters have traditionally used an oil-filled metallic diaphragm that separates the measuring cell from the process fluid. These metallic diaphragms are thin and fragile, which leads to quick wear and tear, especially in the harsh environments found in mines. To avoid the constant

is where a density-compensated level system comes into play. These froth flotation cells have been notoriously difficult to measure an accurate level. Many mining operations had been using a flotation ball, elevated target, and an ultrasonic sensor to monitor the froth level, but this primitive way of tracking continuous level was overwhelmed with difficulties. For starters, the agitated surface of the

flotation cell resulted in rapid elevation changes of the target attached to the ball. Plus, the float would frequently become stuck in the sticky froth, and maintenance to unstick the float and clean it off became routine. The density-compensated level system using electronic differential pressure manages to overcome all the challenges mines previously faced. This new solution lowers maintenance costs and

Measuring the movement of material

provides a higher reliability, instilling confidence in operators and increasing throughput and overall efficiency. VEGA was able to improve mining operations around the world by pioneering a new measurement concept using one of the oldest measurement technologies around.

Radiometric: A non-contact solution

Radiometric technology is right at home in abrasive and volatile environments that are otherwise unforgiving to other process measurement instrumentation, and in mining, these challenging applications are all too common. As a whole, radiometric technology is used to measure continuous level, point level, percent solids in pipes, and the mass flow of bulk solids, but mines around the world mostly use this technology as a way to measure percent solids and mass flow without interfering with the process. Radiometric sensors consist of two parts: a source and a detector. The source is a low-intensity isotope housed inside a steel or lead-lined source holder, which collimates the gamma energy, so it is directed at the detector mounted on the opposite side. Both parts of the sensor are mounted completely external to the process it’s measuring. This results in an easy, non-invasive installation, and it makes any wear and tear on the instrumentation nearly non-existent. The number and size of sources and

The MiniTrac 31 is mounted completely externally and provides a percent solids output to operators, so total throughput can be maximized

detectors will vary from application to application, but how a measurement is achieved works the same. The source is constantly emitting gamma energy aimed at the detector. As mass increases in the process, less radiation reaches the detector, and when mass decreases, more radiation reaches the detector. The internal electronics use the gamma reading to infer a measurement. This principle applies to both percent solids and bulk flow measurements.

Material being excavated from a mine has to move from one step to the next, and it has to be done as efficiently as possible without interruptions. When it comes to solids, there are two main options. Materials are either mixed with a liquid and sent through a pipe as a slurry or conveyed along a belt. A measurement is needed in these steps to ensure everything moves consistently and efficiently. Getting an accurate measurement in either of these applications has its challenges, but for VEGA’s radiometric technology, these challenges are nothing more than another day at the mine. For any pipe carrying a slurry, too many solids can lead to a blockage followed by an extended shutdown for repairs. Too few solids in the slurry, and the mine is running less efficiently, using the same amount of energy to carry less material between each step in the process. To maximize the amount of solids moving through the mine, operators need to know the percentage of solids in the slurry, and this can be done with a radiometric measurement. Traditional percentage of solids measurement methods are invasive, and installation is time-consuming. However, VEGA’s MiniTrac 31 makes this measurement without altering or cutting the pipe. A source and a detector are externally mounted on opposite sides of the pipe, and the amount World Mining Magazine www.ogsmag.com

The WeighTrac 31 measures bulk flow, and it’s mounted around the conveyor belt for an easy installation

of radiation reaching the detector decreases as the amount of solids inside increases. Knowing this measurement gives operators a look inside the process, enabling them to increase throughput by transporting as much solid material as possible without causing a blockage. Conveyor belts move dry goods, and operators need to use the belt to its highest potential without overwhelming it. Any device measuring the weight of the conveyor or the amount of materials flowing needs to be able to withstand vibrations, falling materials, and dirty

environments. Traditional belt scales can measure the weight on the belt, but these instruments require costly and labor-intensive installations. Plus, these same belt scales require regular maintenance and recalibration. Using radiometric technology, operators can still understand the mass flow of solids without a lengthy setup or regular recalibrations. VEGA’s WeighTrac 31 mounts a source over the belt and installs a detector under the belt. This only requires a few bolts to the conveyor frame followed by a simple

calibration. The entire installation is done without ever having to dismantle any section of the conveyor. The WeighTrac 31 source fans out a radiation field across the belt, and as material moves through that field, less radiation reaches the detector. The internal electronics use this gamma reading to infer a bulk flow measurement. These instruments continue to operate like this for years and years with little to no maintenance. This is just one more way measurement sensors give operators a better look at


vega using technology to automate mining processes Having more data available readily and immediately will allow mines to make smarter decisions faster

their process, allowing them to make more informed decisions within the mine.

Mining’s future in Industry 4.0

New and advanced sensor technology has helped mines automate processes, improve efficiency, and save energy. Radar sensors, pressure transmitters, and radiometric detectors helped make that happen, and they’re all a part of the third industrial revolution. The next inevitable step is bringing all of this sensor data together using the industrial internet of things, or IIoT, to make further improvements to efficiency and energy usage. “Industry 4.0,” as it’s being called, will help drive smarter and faster business decisions. IIoT brings smart machines, sensors, advanced analytics, data storage, and people together in one place. The data collected from all these sources within any mining operation is stored in the cloud. Having all this data in once place

allows operations to monitor, collect, share, analyze, and deliver valuable new insights about the systems and processes in real-time. VEGA has already begun making strides to embrace Industry 4.0. VEGA sensors come equipped with digital communication protocols for easier transmission of information to the cloud. These same sensors can provide self-diagnostics with visual codes, and the event memories and historian functions allow users to compare performance over time. Plus, all VEGA sensors can be accessed wirelessly using a secure Bluetooth connection. All of these features are marching toward one inevitable goal – a mine better managed from start to finish.

Embracing technology and adapting to the changes

Technology has changed the face of mining through the course of history. Mines that embraced new technologies

have seen the benefits and flourished, while others who failed to adapt to the changes fell by the wayside. Today’s mines use level, pressure, and density measurements to monitor the various process variables within any single operation. This data gives operators and plant managers a better view of their process, allowing them to make more informed decisions. Intelligently using sensor information allows mines to operate more efficiently, increasing throughput while simultaneously decreasing energy and water usage. At the same time, mines continue to become safer overall. New technology and new ways of doing things will continue to emerge, and mining operations that make the most of these technologies and adapt more quickly will be the mines of the future.

phoenix lighting partnership... in a good light A shared pursuit

In the 1940s, Phoenix teamed up with fellow-Milwaukee manufacturer, P&H. By working together, the two hoped to tackle a long-standing challenge for the mining industry: How can a fragile glass lamp withstand the rigors of these earth moving machines? Shortly after, Phoenix designed and patented the technology to do just that. Now, 75 years later, Phoenix Lighting has continued to put innovations into the market, making mine operators safer and more productive. In that time, Phoenix has formed countless valuable partnerships with industry leaders around the world. Among Phoenix’s most valued partnerships is the one

they’ve formed with BHP. These two organizations have joined together in all corners of the world to bring revolutionary developments to mining.

A shared quest for greatness

Both of these companies date back to the 19th century, but their similarities certainly don’t end there. BHP and Phoenix Lighting share comparable approaches to business with respect to their ethical practices, sustainability and dedication to continuous improvement. As lighting continues to move to LED technology, these companies have joined together to support their collective values. An industry that has been relatively stagnant for decades is

now in a new era of increased efficiency, safety and innovation. BHP mine sites around the globe have been quick to explore the benefits that LED lighting has to offer.

Significant BHP Lighting Projects: Mount Arthur, Australia – Coal

One of the first mines Phoenix worked with to incorporate LED technology was Mount Arthur in Australia’s Hunter Valley. The operators at Mount Arthur were eager to take their lighting efficiency to a new high and their carbon footprint to a new

low. They incorporated Phoenix’s original ModCom® LED floodlights to illuminate two electric rope shovels, as well as their workshop and fuel storage facilities. Eight years later, the LED fixtures are still working like the day they were installed – and have required no maintenance.

Cerrejón, Colombia - Coal

Cerrejón was one of the first mines in South America to invest in LED lighting for mobile equipment. Operators have been working with Phoenix over the last three years to gradually retrofit their fleets of haul trucks, bulldozers and hydraulic excavators with its Sturdilite LED fixture. The majority of Cerrejón’s mobile equipment now utilizes LED lighting, and their operators couldn’t be happier with the results. In addition to mobile equipment, Cerrejón has transformed the way it lights its electric rope shovels. Operators are using Phoenix’s newest World Mining Magazine www.ogsmag.com

  55

LED floodlight – the ModCom® 2 – around the exterior of the shovel and the HDL linear LED fixture in the machine houses. The conveyors at Cerrejón have also been upgraded with 50 of Phoenix’s Conveyo LED fixture. The operators at Cerrejón have recently gone even a step further with regard to safety and innovation by standardizing their fleet of shovels with Phoenix’s Danger Light™ fixtures. These lights project a distinct red beam around the shovel’s perimeter to indicate the area haul trucks should not enter to avoid collisions.

Blackwater Mine, Australia – Coal

Blackwater Coal Mine in the Central Highlands Region of Queensland has been working to set the tone for dragline lighting in Australia. In early

2019, Blackwater proudly completed a full retrofit of the first dragline in Australia with all LED lighting. It’s anticipated that this will be the first of many throughout the region. After testing several fixtures on their equipment over the past two years, the operators at Blackwater ultimately chose Phoenix because its promise of durability and longevity held true. The ModCom 2 provided the maintenancefree lighting they were looking for.

Escondida Mine, Chile – Copper

The operators at Spence Mine in Chile had a unique lighting requirement for their fleet of shovels. The location’s dry air and fine ground composition make for increased dust in the air and, subsequently, lower visibility. In some scenarios, especially for coal mining,

the cooler white of LEDs doesn’t mitigate this challenge. In order to optimize visibility in their high-dust, foggy conditions, they took advantage of Phoenix’s ModCom 2 amber option. The warm, amber light better penetrates the fog and provides Spence Mine with maximized visibility and minimized operator fatigue.

A shared outlook for the future

From the first light fixture to its latest LED innovations, Phoenix has seen a lot in the world of lighting. Throughout the past 75 years, above all else, Phoenix has revered forward-thinking partners like BHP to evolve the conversation about lighting and the mining industry as a whole.

bhp the world’s most valuable mining brand

B

rand recognition might be an unconventional accolade in an industry which tends to recognise the biggest or the most efficient, but as mining changes to accommodate new technology and social and environmental pressures, successful miners adapt to succeed. For the second year in a row, BHP is the standout brand in mining, according to the 2019 ranking of the Brand Finance Mining, Iron & Steel 25. Following a major rebranding exercise in 2017, BHP has seen a 51 per cent increase in its brand value. In the last twelve months BHP has grown its brand value to $6bn, maintained its AA brand strength rating and held its position as the world’s most valuable and world’s strongest mining brand, as well as Australasia’s most valuable B2B brand. Brand valuation and strategy consultancy, Brand Finance was instrumental in developing the internationally recognised standard on Brand Valuation – ISO 10668, which defines a brand as a marketing-related intangible asset. “In a sector where brand and reputation have been largely ignored, now more than ever, mining companies are realising that branding matters,” says David Haigh, CEO of Brand Finance. “BHP is the perfect example of this, using a re-branding exercise to demonstrate its role in Australia’s economy and community, substantially improving its brand value over the last two years.” While branding comes under the umbrella of marketing, there must be substance behind it to give it long term viability, and substance is something BHP has in spades. Among the world’s top producers of major commodities, including iron ore, metallurgical coal and copper, BHP also has substantial interests in oil, gas and energy coal, primarily in Australia and the Americas. BHP lists its corporate purpose as the creation of long-term shareholder value through the discovery, acquisition, development and marketing of natural resources, which it achieves through its strategy to own and operate large, longlife, low-cost, expandable, upstream assets diversified by commodity, geography and market.

IRON

Mention BHP and iron ore immediately comes to mind. It contributes almost half of the company’s gross profit.

bhp the world’s most valuable mining brand ore operations are now concentrated in Australia through Western Australia Iron Ore (WAIO), often described as a jewel in the BHP crown. If iron ore is important to BHP, it’s vital for Western Australia. In the 2016-17 financial year iron ore accounted for 54 per cent of the total value of the state’s resource production, with Rio Tinto being the other major player. The state has the world’s largest reserves of iron ore with 29 per cent, followed by Brazil with 19 per cent, Russia with 15 per cent and China with 12 per cent. The bulk of Western Australian ore (82 per cent) is exported to China, followed by Japan with 9 per cent and South Korea with 6 per cent. WAIO is an integrated system of four processing hubs and five mines, connected by more than 1,000 kilometres of rail infrastructure and two separate port facilities in the Pilbara region of northern Western Australia. At each mining hub – Newman, Yandi, Mining Area C and Jimblebar – ore from mines is crushed, beneficiated where necessary, and blended to create high-grade haematite lump and fines products. Iron ore products are then transported along the Port Hedland– Newman Rail Line to the Finucane Island and Nelson Point port facilities at Port Hedland. WAIO’s Pilbara reserve base is relatively concentrated, allowing development to be planned around integrated mining hubs which are connected to the mines and satellite orebodies by conveyors or spur lines. This approach enables the value of installed infrastructure to be maximised by using the same processing plant and rail infrastructure for a number of orebodies.

South Flank

In June 2018 the BHP board approved capital expenditure of US$2.9 billion (BHP’s share) for the South Flank iron ore project in the central Pilbara, 75 miles northwest of Newman and approximately 5 miles to the south of the company’s existing Mining Area C operation. The South Flank project will fully replace production from the 80 Mtpa Yandi mine which is reaching the end of its economic life. The South Flank deposit itself is vast

– 26 kilometres long, and requiring significant mining infrastructure and operations. Simon Thomas, South Flank Project Director, said the project means hundreds of local jobs and billions of dollars flowing into the Western Australian economy. “We’ve committed a huge $2.1 billion in contract awards so far, with 78 per cent of work committed for completion in Western Australia – more than half of which will be Pilbarabased,” said Thomas. The South Flank project involves construction of an 80 Mtpa crushing and screening plant, an overland conveyor system, stockyard and train loading facilities, procurement of new mining fleet and substantial mine development and pre-strip work. First ore from South Flank is targeted in the 2021 calendar year, with the project expected to produce ore for more than 25 years. Set to be one of the world’s largest iron ore hubs, the South Flank project is currently a quarter way through its schedule. “It’s pretty exciting,” said Thomas. “We’re creating something big. South Flank will be the largest iron ore mining and processing facility built in more than 50 years of iron ore mining in the Pilbara. We’re also integrating the latest advances in autonomous-ready fleets, digital connectivity and modular design.” As in the other JVs which form part of WAIO, BHP has an 85 per cent interest in South Flank, with ITOCHU Minerals

and Energy of Australia and Mitsui Iron Ore Corporation collectively owning the remaining 15 per cent. “Over the past five years at Western Australia Iron Ore, we lifted plant and equipment performance to well above design capacity of 240 million tonnes a year,” said CEO Andrew Mackenzie. “In total, we have increased production by 20 per cent and reduced costs by 50 per cent. We are now the lowest cost iron ore producer and have plans to go lower, as we work towards 290 million tonnes per year on a sustainable basis.”

COAL

BHP’s Australian coal assets are on the other side of the country in Queensland and New South Wales. Its coal business produces thermal coal primarily for use in the electric power generation industry and high quality hard coking coal for use in the international and domestic steel industry. With operations strategically located in areas with seaborne access, the business delivers logistical advantages to its customers. BHP has access to dedicated deep-water ports allowing the use of large capacity vessels to further build on regional logistic advantages. Queensland Coal comprises the 50/50 BHP Mitsubishi Alliance (BMA) and BHP Mitsui Coal (BMC) assets in the Bowen Basin in Central Queensland. BMA is Australia’s largest coal producer and supplier of seaborne metallurgical coal. It is owned 50:50 by BHP and World Mining Magazine www.ogsmag.com

  63


Mitsubishi Development. BMA operates seven Bowen Basin mines (Goonyella Riverside, Broadmeadow, Daunia, Peak Downs, Saraji, Blackwater and Caval Ridge) and owns and operates the Hay Point Coal Terminal near Mackay. With the exception of the Broadmeadow underground longwall operation, BMA’s mines are open-cut, using draglines and truck and shovel fleets for overburden removal. BMC owns and operates two open-cut metallurgical coal mines in the Bowen Basin – South Walker Creek Mine and Poitrel Mine. BMC is owned by BHP (80 per cent) and Mitsui and Co (20 per cent). South Walker Creek Mine is located on the eastern flank of the Bowen Basin, 35 kilometres west of the town of Nebo and 132 kilometres west of the Hay Point port facilities. Poitrel Mine is situated southeast of the town of Moranbah and began open-cut operations in October 2006. In its annual results to the end of June 2019, BHP says that autonomous truck hauling remains in feasibility across its Queensland Coal sites and its Western Australia Iron Ore (WAIO) operations, with potentially over 500 trucks being automated. The company says that safety

  World Mining Magazine www.ogsmag.com

64

incidents with automated trucks are down by over 80 per cent and that it expects to make investment decisions by the end of 2019. “As part of our transformation program, we expect the gradual deployment of autonomous trucks at our Australian coal and iron ore sites to unlock further efficiencies,” said Andrew Mackenzie, CEO, in the investor briefing. “A decision to proceed with our first deployment at Queensland Coal’s Goonyella Mine is expected to be made by the end of next month.” New South Wales Energy Coal consists of the Mt Arthur Coal open-cut energy coal mine in the Hunter Valley region of New South Wales. The site produces coal for domestic and international customers in the energy sector. BHP continues to optimise the mine design by re-opening the Ayredale pit to gain earlier access to a higher margin resource over the next decade. It has also constructed multiple elevated roadways to reduce haulage cycle times and increase productivity.

Cerrejón

In addition to its Australian operations, there are thermal coal operations in

South Africa, the United States and South America. In Colombia, BHP has a one-third interest in Cerrejón, which owns, operates and markets one of the world’s largest open-cut export energy coal mines, in the La Guajira province. Unique in Colombia, Cerrejón also owns and operates integrated rail and port facilities, through which the majority of production is exported to customers in Europe, Asia, and North and South America. BHP’s coal business has delivered over US$3 billion of productivity gains since 2012. Cerrejón is owned in equal parts by subsidiaries of the international mining companies BHP, Anglo American and Glencore. The mine produces over 32 million tonnes of thermal coal a year and has estimated reserves of over five billion tonnes.

COPPER

Copper is an important metal in the BHP portfolio. In Chile, BHP operates and owns 57.5 per cent of the Escondida mine, a leading producer of copper. Located in the Atacama Desert in northern Chile, Escondida is a copper porphyry deposit that also produces gold and silver.


bhp the world’s most valuable mining brand

Following the commissioning of the Escondida Water Supply project and ramp-up of the Los Colorados Concentrator in the September 2017 quarter, Escondida’s two open-cut mines feed three concentrator plants (which use grinding and flotation technologies to produce copper concentrate), as well as two leaching operations (oxide and sulphide). A new desalination plant, opened in April 2018, is another important step forward in Escondida’s water strategy. Construction of the plant required an investment of US$3,430 million. This included two 42" pipelines to transport the water to 3,200 metres above sea level, four high-pressure pumping stations, a reservoir at the mine and high-voltage electricity infrastructure to operate the system. To ensure the electricity for pumping the water, BHP awarded a long-term contract for the development of the Kelar Power Plant, which was originally designed to use coal but was converted into a combined-cycle natural gas plant in order to have energy from a cleaner source. Daniel Malchuk, President of BHP Minerals Americas, asserted that “this

plant reflects our deeply held belief that it is possible to practise sustainable mining, which is both an ethical imperative and a fundamental condition for the business. In Chile, we aspire to cease using fresh water altogether as from 2030. We have progressed in this transition and will continue to do so gradually over the next ten years.”

Pampa Norte

BHP has another two operations in the Atacama Desert in northern Chile, Spence and Cerro Colorado, collectively known as Pampa Norte. In June 2018 BHP agreed to sell the relatively small Cerro Colorado copper mine to private equity manager EMR Capital, but the deal collapsed in December when the buyer could not meet the financial terms of the agreement. The mine has approval to operate until 2023, and will remain in the Pampa Norte division, but will need a new environmental agreement to operate beyond that. Spence, on the other hand, is undergoing a major expansion. The Spence copper cathode operation commenced production in December 2006. In August 2017 BHP announced approval of capital expenditure of

US$2.46 billion for the Spence Growth Option (SGO), which will extend the mine life by more than 50 years. In the first 10 years of operation, incremental production from SGO will be approximately 185 ktpa of payable copper in concentrate and 4 ktpa of payable molybdenum, with first production expected in the 2021 financial year. “Execution of the Spence Growth Option will create long-term value for shareholders in one of our preferred commodities,” said CEO Andrew Mackenzie. “SGO has been extensively studied and we have made significant improvements to project cost and design so that it is able to compete in our portfolio of attractive development options.” The SGO project will draw on experience developed in the construction of the Organic Growth Project 1 concentrator and desalination plant at Escondida, and create up to 5,000 jobs during the construction phase. The project includes the design, engineering and construction of a conventional large-scale sulphide concentrator for both copper and molybdenum with a 95 ktpd nominal World Mining Magazine www.ogsmag.com

  65


ore throughput capacity. In addition, SGO will require a new 1,000 litre per second desalination plant located at Mejillones Bay and a 154 km water pipeline from the plant to the Spence mine site. These will be built and operated by a third party under a build, own, operate and transfer contract. Also in South America, BHP owns 33.75 per cent of Antamina, a large, low-cost copper and zinc mine in north central Peru. Antamina by-products include molybdenum and lead/bismuth concentrate and small amounts of silver.

Olympic Dam

The jewel in the crown of BHP’s copper operations, is, however, Olympic Dam in Australia. Located 560 kilometres north of Adelaide, South Australia, it holds one of the world’s largest deposits of copper, gold and uranium and also has a significant deposit of silver. Olympic Dam is made up of underground and surface operations and operates a fully integrated processing facility from ore to metal. The underground mine is made up of more than 450 kilometres of underground roads and tunnels. Ore mined underground is hauled by an automated train system to crushing,

  World Mining Magazine www.ogsmag.com

66

storage and ore hoisting facilities. The processing plant consists of two grinding circuits in which highquality copper concentrate is extracted from sulphide ore through a flotation extraction process. Olympic Dam has a fully integrated metallurgical complex with a grinding and concentrating circuit, a hydrometallurgical plant incorporating solvent extraction circuits for copper and uranium, a copper smelter, a copper refinery and a recovery circuit for precious metals. In February 2018, BHP announced it was ramping up to full production after an investment of more than AU$350 million. The maintenance and upgrade of the company’s surface operations was the largest planned shutdown project ever undertaken at the mine. The project to upgrade the smelter began in August 2017 and ran for over 100 days. BHP also carried out major upgrade works on the refinery, concentrator, other key infrastructure and site technology. Smelting operations resumed in late 2017 with the first anode cast from the flash furnace in December. In December last year, BHP said it had identified a potential new iron oxide, copper, gold (IOCG) mineralised system, 40 miles south east of Olympic

Dam. In June this year, BHP successfully completed its heap leach research and development trial, confirming the viability of the technology to extract copper, uranium, gold and silver at Olympic Dam. The program began in 2012 and was conducted at a purposebuilt, small-scale heap leach facility at Wingfield run by Bureau Veritas, under direction from BHP and with support from the South Australian Government.

NICKEL

BHP is one of the world’s largest nickel miners, the fifth largest refined nickel producer and a global supplier of nickel to the stainless steel industry. Nickel West is a fully integrated mine-to-market nickel business with over 3500 employees and contractors. All nickel operations (open-cut and underground mines, concentrators, a smelter and refinery) are located in Western Australia. Low-grade disseminated sulphide ore is mined from Mt Keith, a large open-pit operation. The ore is crushed and processed on-site to produce nickel concentrate. Highgrade nickel sulphide ore is mined at Cliffs and Leinster underground mines and Rocky’s Reward open-pit mine. The


bhp the world’s most valuable mining brand

ore is processed through a concentrator and dryer at Leinster. Nickel West’s concentrator plant in Kambalda processes ore and concentrate purchased from third parties. The three streams of nickel concentrate come together at the Nickel West Kalgoorlie smelter, a vital part of the integrated business. The smelter uses a flash furnace to smelt concentrate to produce nickel matte. Nickel West Kwinana then refines granulated nickel matte from the Kalgoorlie smelter into premium-grade nickel powder and briquettes containing 99.8 per cent nickel. Nickel matte and metal are exported to overseas markets via the Port of Fremantle. Over 75 per cent of BHP’s nickel is now sold to global battery material suppliers. A nickel sulphate plant is currently under construction at the Kwinana Nickel Refinery which will produce nickel sulphate, a product used in the lithiumion batteries that power electric vehicles. First production from the nickel sulphate plant is expected at the end of FY2019, while BHP continues to explore options for a Stage 2, 200 kt nickel sulphate facility. Test work also continues on a cobalt sulphate circuit plant at the Kwinana Nickel Refinery.

PETROLEUM

Over the past 40 years BHP has produced oil and gas from its Bass Strait operations, located between 25 and 80 kilometres off the southeastern coast of the Australian state of Victoria. In December 2018 BHP announced approval to develop the western dome of the Barracouta (West Barracouta) gas field in the Bass Strait. The investment of approximately AUD$200 million (BHP

share) is in line with the company’s commitment to meeting Eastern Australian gas demand and maximising resource value. The project will see the development of one of the largest remaining sweet gas reservoirs in Bass Strait, through a two well brownfield tieback into existing Gippsland Basin Joint Venture infrastructure. “The West Barracouta project is an important investment, underpinned by strong economics and rates of return, that will unlock a high quality, new gas resource and help offset Bass Strait production decline at a vital time for the east coast market,” said Graham Salmond, General Manager BHP Petroleum Australia. “We are also assessing other potential development opportunities in the Bass Strait to bring new supply to the domestic market.” The West Barracouta development is expected to achieve first gas from 2021 and demonstrates the Gippsland Basin Joint Venture’s commitment to Bass Strait as a substantial contributor in meeting future domestic gas demand. “BHP is actively engaging with a diverse range of customers for future Bass Strait gas supply,” added Salmond. BHP and Esso Australia Resources Pty Ltd each have a 50 per cent interest in the Gippsland Basin Joint Venture.

POTASH

BHP holds mineral rights in the province of Saskatchewan, Canada. Its 100 per cent owned Jansen Potash Project, about 140 kilometres east of Saskatoon, is believed to be one of the world’s best undeveloped potash projects. Jansen’s large resource endowment provides the opportunity to develop it in stages, with anticipated

initial capacity of 4 Mtpa. Through 2018, the company’s focus was on the safe excavation and preliminary lining of two 7.3-metre diameter shafts. Excavation of both the service shaft and the production shaft was completed by the end of August 2018, at a depth of 1,005 metres and 975 metres respectively. Both shafts reached potash in the Upper and Lower Patience Lake formations during FY2018. Jansen is intended to mine the Lower Patience Lake formation, which lies between 935 metres and 940 metres. In June 2018, the board approved further funding to cover support services at the site, upping the approved investment for the current scope of work to US$2.7 billion. Future work will include installing watertight composite concrete and steel final liners in both shafts. BHP continues to assess how to reduce risk and unlock value as it completes the shafts. At the end of FY2018, the current scope of work was 79 per cent complete. In the meantime, BHP is considering multiple options to maximise the value of Jansen, including further improvements to capital efficiency, optimisation of design and diluting its interest by bringing in a partner. An unrivalled portfolio of high quality growth opportunities will ensure BHP continues to meet the changing needs of its customers and the demand for resources of emerging economies at every stage of their growth. The diversification of the BHP portfolio continues to be its defining attribute.

An Electric Future for Mine Haulage Mining is not a choice – the way we mine is. As part of the electrification journey to make mining more sustainable, GE Transportation has identified three areas of focus: 1. The Electric Drive. These drive systems have been in operation for almost 65 years. Mines have traditionally used them because of

their advantages over other systems, specifically, one third the gearing, 85-percent reduction in bearings as well as durability and low touch times. Moving forward, they will be a must-have in zero emissions systems. Reduction in metal parts reduces the environmental burden of manufacturing these drive systems. 2. Electrification of parasitic loads. In the past, cooling of the drive systems has been done via a large impeller on the alternator or hydraulically driven blowers. With alternator driven cooling, whenever one of the truck’s systems needed additional cooling, the engine would be forced to increase RPMs to spin the alternator and provide more air to the system. Each system had the ability to demand increased engine speed for cooling. With the addition of optimized cooling through electrification, each major system has its own variable speed cooling blower— allowing for cooling “on demand”. This optimization leads to great

productivity, fuel savings and a longer product life. Saving energy saves the environment. 3. Electrification of the truck. One way to accomplish electrification of the truck is to use a hybrid technology to provide energy, with the addition of batteries to supplement the diesel engine. Benefits include lower emissions and lower fuel consumption, among others. The end goal would be to eliminate the diesel engine altogether, with a more capable battery and a charging mechanism. This would allow for zero emissions and lower noise pollution as mines explore a sustainable future. The industry needs to make more sustainable choices in mining, and the path toward innovation is clear. With greater productivity, availability and lower fuel consumption, the future of mining is electric.

everyday commodities

ounded in the 1970s as a metals and minerals marketing company, Glencore has grown by merger and acquisition to become one of the world’s largest resource traders and producers. Its products play an essential role in modern life, from the copper, cobalt and nickel powering the electric vehicle revolution to the energy products helping to keep the lights on.

AUSTRALIA

Australia is an important part of Glencore’s global business as it holds significant interests in a range of commodity industries across all mainland states and the Northern Territory, including coal, copper, nickel, zinc and oil.

Australian coal

Glencore is one of the world’s largest producers and exporters of coal, producing almost 130 million tonnes in 2018. Used in power generation, steel making and industrial processes, coal will remain an essential source of energy for the foreseeable future, and as such, will continue to be an important part of Glencore’s global commodity portfolio. The company operates coal mines in Australia, South Africa and Colombia. In Australia, its activities are concentrated in two major coal regions, the Hunter Valley in New South Wales and the Bowen Basin in Queensland. The company’s interest in coal began with the acquisition in 1998 of the Cumnock and Mount Owen coal mines in Australia. The Cumnock mine is now part of Glencore’s Ravensworth Operations in New South Wales. In 2018, Glencore became Australia’s largest coal miner after it acquired 49 per cent of Rio Tinto’s Hunter Valley Operations for about $US1.14 billion ($1.59 billion). It then also bought Rio Tinto’s interests in Queensland. These deals have helped put Glencore in a dominant position in the Asia Pacific market for high-quality thermal coal. Its NSW Hunter assets also include mines at Bulga, Liddell, Mangoola, Integra, Mount Owen and Ravensworth, while Glencore’s Queensland interests include Collinsville Open Cut, Newlands Coal, Hail Creek, Oaky Creek and Rolleston Open Cut.

Queensland

Collinsville Open Cut, located in the northern part of the Bowen Basin, is Queensland’s oldest coal mine, having operated as an underground or open cut mine for almost 100 years, producing a variety of coking World Mining Magazine www.ogsmag.com

  75


“Glencore is currently progressing plans to extend the life of the Mount Owen Mine by an additional six years and provide an additional 35 million tonnes of run-of-mine coal”

and steaming coal products for both overseas and domestic markets. Collinsville mine is part of the NCA Project, a mining, processing and exporting partnership that also includes the Newlands coal operation and the Abbot Point Bulk Coal terminal. It used to operate as a joint venture between Glencore Coal Queensland (55%), Itochu Coal Resources (35%) and Sumitomo (10%), but Glencore bought out its joint venture partners in Collinsville in September 2016, along with the Newlands coal operation. The Newlands Underground operations reached the end of their scheduled mine lives in June 2016, although open cut mining continues. Glencore also owns a 55% share in Oaky Creek Coal in central Queensland,

  World Mining Magazine www.ogsmag.com

76

which has two underground operations and a coal preparation plant. Open cut operations ceased in December 2006. The underground operations are modern, state-of-the art longwall operations with associated development works. Coal is exported through eastern seaports in Mackay and Gladstone to Japan, Asia, Europe, North Africa and South America. In 2018, as Rio Tinto sought to divest itself of its entire Australian coal portfolio, Glencore picked up its 82% interest in the Hail Creek coal mine and adjacent coal resources in Queensland, as well as its 71.2% interest in the Valeria coal resource in central Queensland for a total of US$1.7 billion. Hail Creek is a large-scale, long-life and low-cost mine producing two-

thirds premium quality hard coking coal and one-third thermal coal for export. Located 75 miles southwest of Mackay, in 2017 Hail Creek produced over 9 million tonnes of coal for export from the Dalrymple Bay Coal Terminal. Valeria is a large undeveloped coal project in the central Bowen Basin, about 40km northwest of Emerald. It contains 762Mt of coal mineral resources, and is expected to produce high-energy, low-ash thermal and coking coal, once developed. Both Hail Creek in Queensland and HVO in New South Wales were successfully integrated into the Glencore portfolio during 2018, revealing $185 million of cost savings/margin improvements available to be realised when the restructure plans are complete.


glencore everyday commodities

Glencore’s Rolleston Open Cut coal mine is located in the southern part of Queensland’s Bowen Basin. Due to its low ash content, the thermal coal extracted at Rolleston Open Cut does not require washing. All coal passes through the coal handling facility for crushing and sizing prior to loading onto trains for export via Gladstone, or into the domestic market.

New South Wales

Glencore is the largest coal producer in New South Wales, employing around 4,800 people in eight mining complexes across three coalfields: Hunter Valley, Western Districts and Southern Districts. Thermal coal, semi-soft and coking coal are all produced from 10 mines in the Hunter Valley, Australia’s

premier coal-producing district, and exported from the Port of Newcastle. Glencore’s Hunter Valley operations include Ravensworth open cut mine, located alongside a coal handling and preparation plant. The mine is a joint venture between Itochu 10% and Glencore 90%. The CHPP assets are owned by the JV but operated by Glencore. The Mt Owen Complex consists of the Mt Owen, Ravensworth East and Glendell open cut coal mines, owned and managed by Mt Owen Pty Limited, a wholly owned subsidiary of Glencore. The integration of these adjacent Glencore owned operations enables all sites to utilise existing infrastructure and coal handling facilities at Mt Owen Mine. Glencore is currently progressing plans to extend the life of the Mount Owen Mine by an additional six years and provide an additional 35 million tonnes of run-of-mine coal. Glendell commenced mining activities in 2008 and currently has approval to mine up to 4.5 Mtpa of ROM coal through to June 2024. Glencore is progressing the environmental assessment for an extension to the Glendell open cut mining operation. The project involves an extension of the open cut mine to the north and the extraction of approximately 135 Mt of ROM coal with mining continuing until 2044. Fifteen kilometres south west of Singleton is the Bulga Complex,

which includes Bulga open cut, Bulga underground operations and the coal handling and preparation plant. Bulga open cut and Bulga underground are managed by Glencore, which is also the majority shareholder, via a somewhat complex ownership structure. Mining finished at Bulga Underground in May 2018. The Ulan Mine Complex is one of the most established coal mining operations in the western coalfields of New South Wales. Until recently Ulan was a joint venture between Glencore (90%) and Mitsubishi Development (10%), but Glencore bought Mitsubishi’s share towards the end of 2018. Mining operations consist of two underground mines and an open cut (not operating since the end 2014). In 2015 Glencore secured approval to expand the underground mine to extract another 13 million tonnes of coal and extend the mine’s operational life by another two years, until 2033. Mangoola open cut is in the Upper Hunter Valley, 20 kilometres west of Muswellbrook and approximately 10 kilometres north of the township of Denman. A relatively new mine, the 100% Glencore owned Mangoola open cut commenced production in November 2010, and won the Australian Mine of the Year award in 2013 in recognition of its water, noise, air and dust management and its community engagement.

glencore everyday commodities Underground resumed production in 2017 after being placed on care and maintenance by then owner Vale, at the completion of longwall 12 in mid 2014. Glencore acquired the assets in December 2015 via wholly owned subsidiary HV Coking Coal. Glencore is undertaking an exploration program from March to October 2019 to obtain information on another seam for possible future underground mining.

Nickel

Glencore’s nickel business produces some of the world’s purest nickel, ferronickel and cobalt. Around twothirds of all nickel is used in the production of stainless steel. The remainder is used for applications including super-alloys, batteries and electroplating. Glencore is one of Australia’s largest nickel and cobalt producers, and with more than 30 years of nickel reserves, it has one of the longest life of mine reserves. Murrin Murrin is a worldclass hydrometallurgical nickel project located between Leonora and Laverton in the northeastern Goldfields region of Western Australia. Operated by Minara Resources, wholly owned by Glencore, Murrin Murrin uses high pressure acid leach technology to recover nickel and cobalt from laterite ore. Processed nickel and cobalt is transported via rail to Kwinana, south of Perth, for export to customers worldwide.

Zinc and lead

Glencore mines and processes zinc and lead ores in Australia, South America, Kazakhstan and Canada. It also smelts and refines zinc and lead at processing operations in Australia, Canada, Spain, Italy, Germany, the UK and Kazakhstan. Over half of Glencore’s total zinc and lead reserves and resources are located in Australia, where Mount Isa Mines and McArthur River Mine host the world’s No.1 and No.2 zinc resource bases. The North Queensland zinc operations include an integrated supply chain comprising mining, processing, transport and logistics, as well as port facilities. The zinc operations at Mount Isa include the George Fisher underground mine, zinc-lead

concentrator, zinc-lead filter plant and lead smelter. Glencore also owns the high-grade Lady Loretta underground mine near Mount Isa, where production was temporarily suspended in 2015 when the price of zinc collapsed. In December 2017, after the price had recovered, Glencore appointed Redpath Australia to run the mine on a contract basis for its remaining six year lifespan. Redpath recommissioned the mine quickly, and was meeting Glencore’s production and development targets by July 2018. Monthly production grew to 100,000 tonnes, with a full production capacity targeting 133,000 t/mth. Another zinc operation, McArthur River Mine in Australia’s Northern Territory is around 970 kilometres south-east of Darwin. Established as an underground operation in 1995, MRM converted to open pit mining in 2006. MRM produces zinc and lead in concentrates which are transported by road from the mine site to Glencore’s Bing Bong loading facility on the Gulf of Carpentaria. Current mine life extends to 2036.

SOUTH AMERICA Coal

In Colombia in South America, Glencore owns a third share (along with BHP and Anglo American) in Cerrejón, one of the world’s largest and lowest-cost open-cut thermal coal

operations. Located in the southeast of the department of La Guajira, close to the border with Venezuela, the mine produces over 32 million tonnes of thermal coal a year and has estimated reserves of over five billion tonnes. Unique in Colombia, the mine has an integrated railway line and shipping terminal, which gives increased efficiency and lower environmental impact. As well as exporting coal, the port and railway are used to transport supplies to the mine. Also in Colombia, Glencore subsidiary Prodeco owns the La Jagua and Calenturitas mines, the port of Puerto Nuevo, and a 39.76% stake in the Fenoco railway. Calenturitas and La Jagua are both open-pit mines in Cesar province in the north of the country.

Copper

In South America, the Collahuasi mine in Chile produces copper concentrate and cathodes. One of the world’s largest copper operations, Collahuasi’s deposits are located on the plateau of northern Chile’s Atacama Desert, 4,400 metres above sea level. Glencore and Anglo American each own 44 per cent, with a Japanese consortium owning the remaining 12 per cent. In Peru, Glencore owns a 33.75% interest in the Antamina open pit copper and zinc mine, 4,300 metres above sea level. Antamina’s concentrator is considered to be one of the world’s largest polymetallic processing plants, World Mining Magazine www.ogsmag.com

“Glencore is one of the world’s largest and lowest-cost producers of chrome ore, ferrochrome and vanadium, and also markets manganese ore and alloys” treating ores containing copper, zinc, molybdenum, silver and lead. Glencore’s Antapaccay copper operation is located in Espinar Province in southern Peru. Acquired in 2013 when Glencore merged with Xstrata, the operation includes an open pit copper mine and processing facilities in addition to port loading and facilities at Matarani. Altonorte is a custom copper smelting operation located near the port of Antofagasta in northern Chile. The Glencore operation has the capacity to process 1.6 million tonnes of copper concentrate from third parties per year. Also in Chile is Punitaqui, a copper mine and concentrator acquired by Glencore as a brownfield development in early 2010, but sold to Vancouverbased Xiana Mining in 2018. In Argentina, Glencore’s mining interests include the copper–gold mine at Alumbrera in the far north of the country, which was until recently jointly owned with Yamana Gold and

  World Mining Magazine www.ogsmag.com

Goldcorp. The mine is now coming to the end of its life, but in March this year the three joint owners signed an integration agreement under which Yamana Gold’s Agua Rica project will be developed and operated using the existing infrastructure and facilities of the Alumbrera mine. Given the proximity of the assets, the parties believe the integration has the potential to realize significant synergies. Agua Rica hosts a large scale, long life copper mineral resource with associated gold, silver and molybdenum while the Alumbrera infrastructure is of significant scale and configuration to be ideally suited for the integration plan. Preliminary studies show the potential for a mine life in excess of 25 years at average annual production of approximately 236,000 tonnes of copper-equivalent metal, including the contributions of gold, molybdenum and silver, for the first 10 years of operation. A full feasibility study is expected to be completed by 2020. When the

integration is finalised, Yamana will own 56.25%, Glencore 25% and Goldcorp 18.75 per cent.

AFRICA Coal

Glencore has been mining in South Africa since 1988 and has a strong presence in both the coal and ferroalloy sectors. The company operates four coal complexes and produces thermal coal for export and domestic power generation. These include the Tweefontein thermal coal complex, consisting of three mines structured into open pit, underground and surface operations. Tweefontein is near Johannesburg in the Mpumalanga province. The iMpunzi Complex, also in the Mpumalanga province, is a large export thermal coal mining operation 110km east of Johannesburg. A third operation in the Mpumalanga province is the Goedgevonden Complex, an open cut mine producing thermal

Finally, Izimbiwa Coal, 100 per cent owner of five mines near Middelburg and Kendal (Graspan, Townlands, Bankfontein, Leeuwfontein and Lakeside mines). Coal is sold both to the domestic market and exported through the Richards Bay Coal Terminal.

Ferrochrome alloys

Glencore is one of the world’s largest and lowest-cost producers of chrome ore, ferrochrome and vanadium, and also markets manganese ore and alloys. The company’s chromite assets are held through a majority stake in the Glencore–Merafe Chrome Venture, and its vanadium assets via a majority shareholding in the Rhovan-Bakwena Vanadium Venture. Through the Glencore-Merafe Chrome Venture, the company interests include the Helena, Magareng and Thorncliffe chrome mines, situated on the Eastern

Limb of the Bushveld Igneous Complex, the Waterval and Kroondal chrome mines near Rustenburg on the Western Limb of the Complex and the Rietvly silica mine, an open-cast operation, situated near Rustenburg. Rhovan is an opencast mine 30km to the north west of Brits in the North West Province of South Africa. The mine primarily produces ferrovanadium and vanadium pentoxide. It also has a number of ferrochrome smelters, the Boshoek, Wonderkop and Rustenburg smelter complexes near Rustenburg use Outokumpu technology. Located in Lydenburg, Mpumalanga, the Lydenburg plant produces ferrochrome which is marketed to producers of stainless and special steel. Lydenburg was the first of Glencore’s operations to use the energy-efficient Premus technology. Ore for the smelter comes from the Helena and Thorncliffe mines in the eastern limb of the Bushveld Complex. The Lion smelting complex is located

close to the Helena chrome mine. Investment since 2007 has resulted in this becoming Glencore’s largest proprietary Premus smelter, with 720,000tpa ferrochrome capacity. Premus is designed to reduce electrical energy consumption by using waste gas and heat. Lion’s specific energy consumption is 28% less than the South African average smelter’s energy consumption

Copper and cobalt

Glencore is of the world’s largest producers and marketers of copper, producing 1.45 million tonnes in 2018 and selling 4.5 million tonnes through its marketing business. The company mines and processes copper ore in the key mining regions of Africa, Australia and South America, and sources and recycles copper scrap in North America and Asia, as well as smelting and refining copper around the world.

NORTH AMERICA

Turning back to nickel, in Canada, Glencore’s Sudbury Integrated Nickel Operations (Sudbury INO) include exploration, two underground mines (Nickel Rim South and Fraser), Strathcona Mill and the Sudbury Smelter. The company has been mining nickel-copper ores in the Sudbury area of northern Ontario since 1928. The facilities are spread throughout the 60 kilometre-long, oval-shaped geological formation known as the Sudbury basin. Nickel and copper are the primary metals but cobalt and precious metals, such as gold, silver, platinum and

palladium are also produced. Sudbury INO is looking to develop one of the world’s first mines wholly operated by battery electric-powered vehicles (EVs). The Onaping Depth Project, currently under construction and expected to come on-stream in 2023/24, is collaborating with EVproducers to ensure all parties are fully prepared for an all-electric mining operation. Just a few years ago, Sudbury INO was at a point where, without further investment, the site’s mines were expected to reach the end of their life cycle as early as 2023. Onaping Depth offered the potential opportunity to extend Sudbury INO’s mine life, but given the depth of the deposits it demanded a commitment


glencore everyday commodities

to innovation. At 2,600 metres deep, a major portion of the expected operating costs for the mine infrastructure is for the energy used to power the ventilation required to eliminate exhaust contaminants, as well as the heat and the refrigeration needed to maintain reasonable temperatures. Caterpillar, the world’s largest construction equipment manufacturer, has been testing the proof-of-concept battery electric R1300 at Sudbury INO with the machine running in trials alongside its diesel equivalent. Caterpillar used the insight gained from its proof-of-concept testing to develop the R1700 XE – its first commercial battery electric Load-Haul-Dump (LHD). Through using EVs, Onaping Depth is

expected to reduce its energy usage by 44% for ventilation systems and by 30% for cooling equipment, compared to an equivalent diesel-fuelled operation. EVs have no emissions, resulting in less pollutants and improved occupational health benefits. They are quieter to operate, experience less wear and tear, and have lower maintenance needs due to their simpler machinery. Using EVs, Sudbury INO’s new mine will reduce greenhouse gas emissions by 44% and deliver considerable cost savings through reduced fuel and energy usage. Also in Canada, in the far north of Quebec, is the Raglan mine property, which has four underground mines and associated infrastructure, with highgrade ore deposits of nickel and copper spanning the nearly 70km property. The ore extracted from Raglan Mine is crushed, ground and processed on-site to produce a nickel-copper concentrate, which is then sent to the Sudbury Smelter for further processing. The concentrator treats approximately 1.3 million tonnes of ore yearly, resulting in more than 30,000 tonnes of nickel-inconcentrate annually.

Raglan Mine’s current operations, which began in 1997, are expected to gradually cease as from 2020, but the Sivumut Project is being developed to extend the life of the mine for an additional 20 plus years. In his comments for Glencore’s half year results to 30 June 2019, CEO Ivan Glasenburg concluded: “Looking ahead, we are confident that commodity fundamentals will move in our favour and that our diverse commodity portfolio will continue to play a key role in global growth and the transition to a low-carbon economy. “Our asset teams are focused on delivering the full potential of our business, which together with our promising range of commodities, should see us well positioned for the future. Through continued constructive collaboration, we remain focused on creating sustainable long-term value for all stakeholders.”
