was initially surprised to hear that, according to accountancy firm Ernst & Young, by the end of the first quarter of 2016 the global value of mergers and acquisitions in the mining sector had plummeted by 45 per cent year-onyear. There were 72 mergers and acquisitions globally in the first quarter, the EY report said, which was 17 per cent down on Q1 last year.

Surprised because the industry is struggling in the wake of a decline in demand and the consequent fall in commodity prices. Some of the world’s biggest miners are said to be looking to sell off unprofitable mines and cash-strapped smaller miners need to sell assets to finance their debt.

We covered an earlier report by EY in our March issue which concluded that “financial distress among mining and metals companies will shape M&A activity in the sector in 2016, with divestments expected to pick up pace on the back of volatility and uncertainty on the timing of a recovery”. So why is it not happening?

Martin Ashcroft

Then I read that one of the biggest deals of the year, the $775 million acquisition of Indonesia’s Martabe mine, one of the world’s largest gold mines, by an international consortium led by private equity firms EMR Capital and Farallon Capital, had taken over two years to negotiate.

This deal serves as a simple reminder that, in times of uncertainty, trends take longer to establish themselves. When the industry is booming, investment knows no bounds.

Investors can’t buy quickly enough, for fear that somebody else might beat them to a tasty asset.

When everyone wants to sell but buyers have limited funds, however, it’s only natural that potential deals should come under closer scrutiny. It’s also a sign of the market that more purchasers are coming from the ranks of private equity firms, rather than miners themselves. These people are interested only in the best assets, and they are notoriously careful with their money. I think we can expect some more distress before the pace picks up.

Mining costs and savings

W

hat do you do when management tells you to cut your engine maintenance budget by $250,000 (or more)?

After the panic subsides, you might begin by sorting your itemized budget expenses from high to low. Where are you spending the most money on engine maintenance? Human resources usually represent a large portion of your expense profile; however, unless they are sitting around playing cards all day, this is probably the last place to look when it comes to making cuts. Finding and keeping good heavy-duty equipment mechanics/technicians is becoming a major management challenge these days. Sending staff home may cut your costs in the short term, but this tactic could have dramatic repercussions in the long term. In most cases, human resource reductions should always be an alternative of last resort.

“For the last three years the mantra at mining companies has been cut costs and cut budgets. Projects have been delayed, expansions have been shelved, exploration stalled and expenditures deferred…belt-tightening extends from the top tier right through the industry…”

Excerpts from article by Frik Els published 9/21/15 (Mining.com)

What do you do?

Well, we know that miners are good at digging holes, but what if you simply cannot dig yourself out of the hole you are currently in today? One way is to sort through your historical budget expenses by category (in detail) in order to discover areas where you can obtain the greatest savings. Also, you may uncover some insights into your cost structure, especially as you research into some of the higher dollar expenses. What can you eliminate? What items are ‘must have’ versus ‘nice to have’ when it comes to operating the business? You might contact your key suppliers and challenge them for meaningful savings (i.e., not just one time low single digit percentage discounts). Some companies look to find creative ways to squeeze another 500 hours from an engine, but extending maintenance intervals can be a dangerous decision.

WORLD MINING MAGAZINE www.ogsmag.com

• IPD: Helping Mines Survive “Miners become leaner and meaner to thrive in a lower price environment…the world’s 4th largest iron ore miner stated that lowering operating costs enabled the company to generate strong cash flows…miners and developers are doing all they can to merely survive, while they continue to work on reducing costs and increasing operational efficiencies.”

Excerpts from article published by S&P Global Platts (source: The Barrel: The essential perspective on global commodities)

How else can you save a little today, and possibly save even more tomorrow?

Along the way to figuring out how to reduce your budget expenses, you will be faced with considering changes to your current processes. Change is hard, and you may face resistance and variations of “that is the way it has always been done here”. You will most likely want to do the commonly acceptable changes, such as reducing overtime expenses and other necessary steps.

However, changing a long valued process, such as considering alternative sourcing, can provide significant savings and may be the key element in achieving your bridge savings goal.

Cutting Costs 101 One area of potential savings for owners and operators of heavy equipment originates from a question that has been posed for a very long time…whether or not to source all parts and service from an OE dealer, or consider aftermarket alternatives? Typically, high maintenance expenses for a large piece of heavy equipment are often directed to OE dealer resources without any other consideration.

Thus, this is one logical place to look for more savings.

You may ask yourself, “What are the key things to consider in making a change to procuring parts and services from the aftermarket?” To begin, who is the aftermarket company? How long have they been in business? What are their capabilities, especially with regard to technical expertise relating to their parts and your equipment? What parts do they offer? Do they offer the latest technologies? What quality assurance processes do they implement? What is the scope and range of their business? How do they keep up with product updates? What kind of savings can you expect?

Dollars & Sense When companies and industries are stressed, such as during the difficult economic conditions that we are currently experiencing in the mining industry, looking for cost savings may require changing traditional ways of doing business.

Consider the dollars involved and what makes sense... reducing budget expenses only in ways that make sense to the sustainability of your business is a prudent approach.

Purchasing your engine repair parts from a reputable aftermarket supplier is one such consideration in support of sustainability.

Considerations in mining operations

Engines in Mining The mining industry is highly dependent on engine power for many operations, which can be directly or indirectly involved with power generation, a variety of materials actions (drilling, extraction, processing and movement), and also in various support roles. Engines power a wide range of important mining machines, such as blast hole drills, excavators, haul trucks, front-end loaders, and more. Also, mining operations occur in some of most difficult operating environments in the world, and mining equipment engines must also endure high load operations, often of a continuous nature.

In order to promote operations continuity, it is important to maintain strong processes associated with engine repair and maintenance to ensure maximum uptime. In addition to the service side of maintenance processes, your selection of engine repair parts can have a dramatic impact on your bottom line. Quality parts that are engineered specifically for heavy-duty operations are often considered a ‘must have’ in the mining industry.

• IPD: Helping Mines Survive

The Independent Aftermarket: YOU HAVE A CHOICE! On many engines, specifically after an engine series reaches its first or subsequent expected overhaul periods, equipment owners must make a decision to continue to return to the original equipment manufacturer for parts and service, or contact an independent servicer and/or specify aftermarket repair parts for their engine service. Some manufacturers, such as IPD, specialize in engineering and manufacturing more recent engine models as they approach their first overhaul period.

The independent aftermarket is made up of companies that are independently owned, and not typically associated with the OE manufacturer. The message to equipment owners is simple, YOU HAVE A CHOICE… to select aftermarket parts for your engine servicing, often at a substantial cost savings compared to OE parts.

A Change in ‘Mineset’: Not all parts are made the same!

Engine parts that are engineered for ‘heavy-duty’ equipment and usage are often difficult to discern. If you purchased mining equipment, then it can be inferred that the original engine specification is also of a heavy-duty nature. Of course, engine swaps have been known to have occurred in used equipment, so you always want to only source heavy-duty components for any engines you are using for mining.

Psi 1595-1885 2320-2610 2610-3190 3480

One key component in each engine is the piston. The history of pistons starts long ago with 1-piece aluminum pistons, which later evolved to a 2-piece articulated design with steel crowns in order to accommodate high combustion chamber pressures (and heat).

Later model engines required an evolution to a 1-piece all steel piston for ever-increasing pressure requirements, and more recent designs evolved to friction/inertia welded pistons designed for even higher pressures. In general, under most circumstances, it is not recommended to mix piston design types in the same engine.

IPD is a unique aftermarket parts manufacturer, with over 60 years of experience servicing the mining industry, and providing the most up-to-date line of engine repair kits and components. IPD uniquely engineers high quality pistons for both old and newer model engines. IPDSteel pistons were designed specifically for newer applications, and IPD now owns several patents (and a patent-pending) on all of the steel variation piston designs noted above, so you have a choice when it comes to parts sourcing and cost savings. IPD also looks for opportunities to innovate, such as with C18/C32 application IPDSteel pistons.

Piston & Liner Assy. (Cylinder Kit) for C32 engine

Long ago, IPD pioneered the application of induction-hardening on cylinder liners for heavy-duty applications, and continues this process on most IPD liners sold today. More recently, a unique steel construction cylinder liner design for C18 and C32 engines is specified for added cylinder strength, and IPD engineered and developed an IPDSteel alternative to the OE design. Don’t be fooled by lesser designs, such as a C18/ C32 cylinder liner made of cast iron (not steel) that could be found in the market recently, and which resulted in failures in the field.

In-Frame Overhaul Gasket Set for C27 Engines

Similar heavy-duty engineering and design statements can also be made for an engine’s gasket set, which is an important part of every engine overhaul. Lesser companies specify automotive specification materials for heavy-duty applications, which is a failure waiting to happen. IPD only specifies heavy-duty gasket materials to ensure that each set performs as expected in real-world mining operations. Also, IPD specifically brands almost all IPD gasket components, so that you know that you are using IPD specification, high quality materials that meet or exceed OE performance levels.

Not all suppliers are the same!

Some suppliers are simply ‘repackagers’, selling parts from a wide range of manufacturers that may have a variety of capabilities and competencies. Simple repackagers may be able to offer very low prices because they may not own the product specifications, nor conduct any engineering and/or quality assurance processes, instead relying only on the manufacturer. Also, some suppliers do not attempt (nor have the capability) to implement product innovations that can help to resolve field issues when they arise, even in some cases with OE parts. Lastly, some suppliers do not have the expertise to provide technical data, nor to understand and specify (and validate) complicated parts specifications, nor to configure kits and solutions that can help you with your business.

innovative parts Pistons, Pins And Rings IPD pistons include such critical/precision design features as ovality, optimized pin bores, and special coatings for improved functionality and corrosion/ wear resistance. One development priority is to achieve optimal piston and pin interaction via precision machined pin bores or using aluminum bronze alloy bushings. Design validation includes 3D modeling, finite element analysis (FEA), and a variety of testing methods (such as hydro pulsator, ultrasonic, mechanical, and actual engine runtime). IPD typically considers over 100 key design specifications per piston. From OE level critical specifications, to precision CAM and CNC machining, to specialty finishing and final quality sampling, IPD pistons set a standard of excellence.

Past IPD piston innovations (such as specialty pistons with an added ring and one piece oil dams on applicable steel pistons) have helped to resolve field issues with OE designs. IPDSteel™ patented and patent-pending pistons are heat treated for strength, durability, heat and wear resistance, thermal management and dimensional stability. IPD piston designs include as follows: • • • •

Friction welded (Patent #9216474) for very high cylinder pressure applications 1 piece (Patent-pending) featuring an exclusive one piece oil dam plate for improved reliability versus 2 piece designs 2 piece articulated (Patent #7938093) joining an IPDSteel crown to an aluminum skirt 1 piece aluminum

In addition, IPD piston pins are case hardened for strength and durability, and are engineered with very high quality material specifications, such as nickel chromium and molybdenum alloy steel for durability.

IPD piston rings sets are application-specific for maximum performance and durability.

ABB

to automate conveyor system at Chilean copper mine

news in brief

Largo Resources Ltd produced 780 tonnes of vanadium pentoxide (V2O5) at its Maracás Menchen Mine in May 2016, surpassing by 7 per cent its previous record for monthly production of approximately 730 tonnes set in April this year. Largo also achieved a new daily production record on Monday 23 May of 34 tonnes of V2O5 (representing approximately 128% of the plant’s daily nameplate capacity) and a weekly production record of 198 tonnes of V2O5 during that week.

“With two months of consistent and record breaking production, our team in Maracás has once again demonstrated the on-going success of the project,” said Mark A. Smith, president and chief executive officer.

P

ower and automation technology group ABB has won an order from Tenova TAKRAF Chile to automate one of the world’s most powerful conveyor belt systems at Chuquicamata Mine in Chile. The belt system will deliver copper ore from the underground mine directly to the concentrator plant, 13 kilometres away from the mine site.

When complete, the conveyor system will be one of the world’s largest and most complex, covering steep gradients and long distances. In the final stage the system will transport over 11,000 tons of material per hour, the same freight as approximately 158 wagon trains.

The order consists of a complete power and automation solution which includes products such as gearless drives, motors, instrumentation and power product supply. The equipment will be custom engineered to on-site requirements in order to optimally power, control, measure and actuate the conveyor system. The solution will fully integrate the belt’s power and automation through ABB’s flagship control system, 800xA, combined with mining conveyor control program (MCCP), ensuring optimum power quality and control across the entire system.

Chuquicamata, one of the largest open pit copper mines and the second deepest open-pit mine in the world, is situated 1,650km north of Santiago, Chile. The mine, popularly known as ‘Chuqui,’ has been operating since 1910 and is owned and operated by Codelco, the world’s leading copper producer.

A new underground mine is being developed to access the ore body beneath the present open pit mine. Scheduled to begin operations in 2019, the new mine will significantly expand the capacity of the mine.

A key feature of the ABB solution is the gearless conveyor drive system, a state of the art solution to meet the extremely high load requirements and the necessary power availability, and which would not have been achievable with a conventional drive solution.

The gearless conveyor drive system eliminates the gearbox from the motor, significantly reducing the number of main wear parts, resulting in less maintenance and a longer lifespan of the solution.

A further advantage is the reduction in the amount of instrumentation required.

Having fewer parts increases the reliability and efficiency of the overall conveyor system.

Cyprium Mining appoints Bergmann for Potosi Silver Mine development in Mexico

C

yprium Mining Corporation has signed an agreement with Chihuahua, Mexico based mining contractor Bergmann Mexico SA de CV with respect to mine development and other mining activities including drilling, blasting and extraction of mineralized material at the Potosi silver mine.

“We appointed Bergmann in February to carry out the Potosi shaft #3 project,” said Alain Lambert, chairman and CEO of Cyprium, “which consisted in the rehabilitation and improvement of the extraction capability of the shaft as well as improvement of infrastructure, security and preparation of prospective

mining areas at levels 2 to 4 of the mine. Not only did Bergmann complete the project on time and

mine as it was the contractor used by Cyprium’s joint venture partner when the mine was last in production a few years ago.

Under the supervision of Cyprium’s head geologist Roberto Banda, Bergmann will perform mining development services including pre-mining development activities, extraction of minerals in mine and mine development on a “cost plus” basis. As part of the agreement, Bergmann will also be evaluating and making a recommendation on the possible rehabilitation of shaft #1 in order to provide access to additional levels of the mine.

“Bergmann has a deep and extensive knowledge of the Potosi mine” on budget but they also contributed several ideas which strengthened the original plan. “ He added that Bergmann had a deep and extensive knowledge of the Potosi

Orex continues to hit silver on

Sandra Escobar Project in Durango

O

rex Minerals Inc. has announced that its Phase-II diamond drilling program continues to intercept silver mineralization on the Sandra Escobar Project in Durango, Mexico. Assays for eight more drill holes - SA-16023 to SA-16-030 in the southeastern region of the project - are now available.

Six of the eight holes are in the Main Zone, but prospecting has also identified the geological horizon for disseminated silver mineralization

on a separate hillside, Cerro Chato, northwest of the Main Zone. Two test reconnaissance holes in the Cerro Chato Zone have confirmed it as a favourable target area. More mapping and drilling is being planned for several zones, including Cerro Chato, in the next phase.

Sandra Escobar is situated north of the town of Tepehuanes, Durango, in the heart of the ‘Mexican Silver Trend’, which hosts some of the world’s largest silver camps and deposits, including Fresnillo, Guanajuato, La

Pitarrilla, La Preciosa, Real de Angeles and Zacatecas. Orex has the right to earn up to 65% ownership interest in the project, which is being advanced under an option agreement with Canasil Resources Inc. “Drilling continues to yield thick intercepts of disseminated silver mineralization showing continuity in the Main Zone,” said Orex President, Gary Cope. “Identification of silver on Cerro Chato and in several other areas bodes well for the next phase of exploration.”

Potential lithium

First gold expected at Challenger Mine

brines investigated in Australia

T

wo salt lakes in South Australia are to be investigated for their lithium potential. Adelaide Resources Limited has secured the opportunity to prospect for lithium concentrations at Lake Gilles and Lake Acraman. The two lakes are situated in the Eyre Peninsula about 600km northwest of South Australia’s capital, Adelaide.

Adelaide Resources managing director Chris Drown said the surrounding rocks and soil were an indication that there may be traces of lithium in the lake brines. “South Australia sits in one of the arid belts, the one south of the equator. Lithium brine deposits develop here,” he said. “We have lots of salt lakes in South Australia in Lake Eyre, Lake Torrens, Lake Gilles and Lake Acraman.

We are going to see if there are elevated signs of lithium in two of those lakes. It’s a very new sort of exploration target.”

The new owner of a remote gold mine in South Australia expects first production by late June.

The underground Challenger mine, located about 750km northwest of the South Australian capital Adelaide, was acquired by WPG Resources Limited in March 2016, along with other exploration assets.

Addressing the Paydirt 2016 South Australian Resources and Energy Investment Conference in Adelaide, WPG managing director Martin Jacobsen said the company predicted a mine output of about 50,000 ounces of gold over the following 12 months.

“There is over 500,000 ounces of gold in the ground there and it is our intention to grow production,” Jacobsen said. “Our best case scenario is for WPG to produce in excess of 45,000 attributable ounces of gold in the next financial year and this assumes no additions to the gold resource at Challenger.”

Challenger has a production history of one million ounces of gold but output was suspended pending completion of the sale to WPG. The company is currently undertaking essential maintenance works on the mine infrastructure prior to recommencing milling operations. The restart will be fuelled by stockpiled ore and fully developed underground mining stocks.

Challenger’s carbon-in-pulp processing plant has a capacity of 650,000 tonnes a year and will eventually also take ore from WPG’s nearby Tarcoola gold mine. Jacobsen said WPG would continue with its exploration work and he was confident of increasing operations at Tarcoola. “There are nearly a million tonnes of resource at Tarcoola and there is also potential for finding other deposits where we will be doing further exploration work.”

The Challenger deposit was discovered in 1995 by Dominion Mining. The first shipment of gold bullion from the mine was made in 2002.

As society becomes more dependent on technology, metals like lithium are in high demand. Lithium extraction is a billion dollar business that is expected to quadruple to US$6 billion by 2020.

Worldwide, lithium is extracted from two principal sources - hard rock deposits and lithium brines associated with salt lakes. Australia is one of the leading suppliers of lithium but does not have as many known sources as its competitors.

More than 50 per cent of the world’s lithium deposits are found in South America, increasing the need for more sources to be found in other parts of the world. “Lithium is a metal in high demand,” said Drown.

“It is at the forefront of technology development and manufacturing. There is an increasing demand for lithium in batteries, solar energy storage and electric motor vehicle industries.”

big three reduce iron ore forecasts

B

HP Billiton and Vale have both cut their production forecasts for iron ore this year, and while Rio Tinto expects production to remain on target for a record 350 million tonnes in 2016, it reduced its outlook for 2017 shipments by some 15 million tonnes.

In its third quarter report BHP cut its forecast for the year by 10 million tonnes to 229 Mt. Vale said in a statement that “Production in the first quarter and the plan for the rest of the year suggests an annual production towards the lower end of our original guidance of 340-350 million tonnes.”

That’s not to say that any of the big

three are admitting a change of strategy, however. BHP said it had reduced guidance at Western Australia Iron Ore (WAIO) “as a result of adverse weather and the initiation of an accelerated rail network maintenance program.”

The suspension of operations at the Samarco mine in Brazil after last November’s dam burst has also affected this year’s production for both Vale and BHP, for whom the mine is a 50/50 joint venture.

Rio also invoked bad weather and problems with its network of robot trains as factors affecting next year’s production.

• Spotlight on graphite

Australian flake graphite deposit gains mining approval

Renascor to fast track Arno graphite project

T Lincoln Minerals’ managing director, Dr John Parker

A

mining lease has been granted to develop Australia’s highest-grade flake graphite deposit. Lincoln Minerals has been granted a 21-year lease for the 300-hectare Kookaburra Gully graphite project on South Australia’s Eyre Peninsula, which is also in the world’s top 10 deposits based on grade.

The shallow but high-grade resource, located 35 kilometres northwest of Port Lincoln, extends to at least 125m depth, remains open at depth and along strike, and hosts total indicated and inferred mineral resources of 2.20 million tonnes grading 15.1 per cent total graphitic carbon (TGC). It also abuts the Lincolnowned and Koppio graphite mine which, as a second potential source for the Kookaburra Gully mine, adds

“South Australia is home to more than 75 per cent of Australia’s JORC graphite resources” an inferred mineral resource of 1.85 million tonnes at a grade of 9.8 per cent TGC into the overall project’s mining potential.

The Kookaburra Gully application was lodged in October 2014. The company is targeting an output of up to 40,000 tonnes per annum of high-grade graphite concentrate for an initial mine life of at

least seven years. Lincoln chairman Yubo Jin said the granting of the mineral lease was a key milestone that would allow the company to progress from “project explorer and developer to an emerging graphite producer, in an industry at the forefront of the growing global green energy market”.

Graphite has seen a resurgence in price in recent times due to increased demand from applications such as lithium-ion battery technology for electric cars and the novel substance graphene. It is also at the forefront of the growing global green energy market.

A proposal to build a solar thermal power station in Port Augusta, about 250km north of the Kookaburra Gully site, is being considered. If it goes ahead, the power station would require at least 17,000 tonnes of graphite. In the proposed Solastor system, a tower mounted, 10-tonne graphite solar thermal receiver is heated to 800°C and used to convert water to steam, which is then used to generate electricity in a steam turbine generator.

South Australia is home to more than 75 per cent of Australia’s JORC (Joint Ore Reserves Committee) graphite resources, largely on Eyre Peninsula.

Lincoln managing director John Parker said the company would work closely with the South Australian Government, the District Council of Tumby Bay and the local community throughout the remainder of the approval process. He said mine construction and production was targeted to commence in 2017.

he owner of Australia’s newest and largest graphite project will fast track its development through to production.

Renascor acquired the Arno project on South Australia’s Eyre Peninsula late last year with much of the resource contained within 25 metres of surface and remaining open along strike.

The company has adopted what it says is a three-tiered immediate term work program to ensure rapid development of the January 2016 discovery.

Addressing the Paydirt 2016 South Australian Resources and Energy Investment Conference in Adelaide, Renascor Resources’ managing director, David Christensen, said the Siviour deposit within the Arno project was of a calibre that warranted fast tracking.

“Our immediate focus is to conduct further drilling to expand the known graphite resource, undertake further mineral processing testing and complete a scoping study by the third quarter this year,” Christensen said.

“Successful completion of these near term goals can then pave the way for offtake negotiations, permitting, feasibility, construction and production scheduling.”

Located just south of Cowell, about 230km northwest of the South Australian capital Adelaide, Siviour has an indicated and inferred resource of 16.8 million tonnes at 7.4 per cent total graphitic carbon, for 1.24 million tonnes of contained graphite at a cut-off grade of 3 per cent TGC (total graphitic carbon). “We have already established scale, very favourable potential stripratio and excellent in situ flake size for Siviour,” Christensen said.

“Renascor will now move through the very critical metallurgical and product satisfaction phases. Should the results continue in a positive fashion, Siviour looks likely to provide much needed diversity of supply from here in Australia to a global market currently dominated

by Chinese production,” he said.

Graphite is expected to continue to be a key commodity for battery manufacturing, steel refractories and lubricant development.

Planetary Resources raises funds for Earth observation

P

lanetary Resources, Inc, the asteroid mining company, has secured US$21.1 million in Series A funding to deploy and operate Ceres, an advanced Earth observation business aimed at improving the understanding and management of natural resources on our planet. Earth observation will be another aspect of Planetary Resources’ operations in addition to prospecting and mining asteroids.

Conceived from the company’s vision for the exploration and utilization of asteroid resources, Ceres features the first commercial infrared and hyperspectral sensor platform, and will leverage Planetary Resources’ Arkyd spacecraft to deliver affordable, on-demand Earth intelligence of our natural resources on any spot on the planet. While typical satellite imagery provides only a picture, Ceres will provide actionable data with higher spectral resolutions – going beyond what the human eye can see – by measuring thermographic properties and detecting the composition of materials on Earth’s surface.

Planetary Resources is currently testing Ceres’ sensor platform and will demonstrate the technology in space with an upcoming scheduled launch of the company’s Arkyd 6 spacecraft onboard a Space X Falcon 9 rocket. The mission will validate the thermographic sensor and supporting technologies for the Arkyd series of spacecraft.

“As we continue toward our vision of the expansion of humanity and our economy into the Solar System, our team has been working on the critical technologies required to detect and identify the most commercially viable near-Earth asteroids and their resources,” said Chris Lewicki, President and CEO, Planetary Resources, Inc. “To characterize these resources, it required more than just a picture, and our team has developed advanced spectral sensors to serve this need. We have also created new technologies for onboard computing, low-cost space platforms, and are now applying these transformative technologies in additional markets.”

The imaging technology is integrated onto the Arkyd spacecraft and deployed as a constellation of 10 satellites in low-Earth orbit. The constellation will provide global monitoring capability to benefit multiple industries including agriculture, oil & gas, water quality, financial intelligence and forestry. Ceres can analyze the spectral signatures of crops and provide customized

information to growers, identify energy and mineral resources, and monitor pipelines and remote infrastructure.

The system can also track toxic algae blooms, monitor global water quality and enable the detection of wildfires in their earliest stages.

Pershing Gold approaches production at Relief Canyon Mine

E

merging gold producer Pershing Gold Corporation has provided an update on progress towards production at its Relief Canyon Mine in Pershing County, Nevada. Relief Canyon includes three open-pit mines, expanding adjacent open-pit-able gold deposits, and a state-of-the-art, fully permitted and constructed heap-leach processing facility.

“This second quarter is a pivotal time for Pershing Gold,” said Stephen D. Alfers, president, CEO and executive chairman. “For more than a year now, we have been looking forward to an updated resource, a PEA and a decision on the restart of the Relief Canyon Mine.

“The completion of the pit slope study, the resource update, the PEA and the receipt of the permit modification should allow us to maximize the efficiency of the mine plan and provide us with key information as we rapidly continue towards production at Relief Canyon.”

Pershing Gold is currently in the final stages of approving its 2016 drilling program and is completing geophysics to define additional targets. It has retained Golder Associates of Reno, Nevada to initiate pre-feasibility level geotechnical

studies for the Relief Canyon Mine, which will outline pit slope design criteria and will define a follow-up pit slope geotechnical program, essential steps in Relief Canyon’s path to production.

Firstgold Corp. purchased the mine In 1995, but this company was partly financed by Chinese investors and in December 2009 a federal agency (the Committee on Foreign Investment) eventually ruled that the mine was too close to facilities associated with a Naval Air Station to justify a foreign presence, and the company was subsequently forced into bankruptcy.

Pershing Gold Corporation became the owner of the mine in August 2011 and its landholdings now cover approximately 25,000 acres, including the Relief Canyon Mine and lands surrounding the mine in all directions. This land package provides Pershing Gold with the opportunity to expand the Relief Canyon Mine deposit and to explore and make new discoveries on nearby lands.

In January 2015, Pershing acquired exclusive mining rights to roughly 3,000 acres from Newmont Gold, and management intends to make additional strategic acquisitions.

Copper purification system to cut shipping costs

N

ew technology to improve the purification process of minerals will allow a major Australian miner to significantly reduce shipping costs. South Australian company OZ Minerals has designed a refining process that increases the quality of its copper concentrate and exponentially reduces export costs.

OZ Minerals’ hydromet technology improves the leaching process and purifies copper concentrate by reducing the amount of iron. Project director at the company’s Carrapateena mine Brett Triffett said hydromet’s unique ability allowed it to significantly reduce the shipping weight, which would save the company tens of millions of dollars in export fees.

because of the quality of their copper concentrate. This process is unique to us. We’ve done it to suit our concentrate and there is no one else in the world that’s doing anything like this.”

Triffett said OZ Minerals had a global growth aspiration and was looking to expand its export markets to include big copper manufacturers in Japan and Korea. The company is currently engineering a plant and finalising costs to demonstrate the feasibility of the process.

In April OZ Minerals was awarded the Statewide Super Innovation in Resources Award for its hydromet technology at the inaugural South Australian Resources Industry Awards. The judging panel included the leader of the Minerals and Energy

“This process is unique to us. We’ve done it to suit our concentrate and there is no one else in the world doing anything like this” “We were planning on producing a product that was about 40 per cent copper and that product would be shipped to our customers in Asia and Europe and they would make that into something that was 100 per cent copper,” he said.

“It’s a leaching process. We take that 40 per cent product and use a combination of reagents to dissolve the iron out of the concentrate. It then upgrades it to the targeted 60 per cent.”

Copper remains a high demand mineral despite its drop in value over the past 12 months from US$2.91 per pound to $2.07/LB. It is primarily used to make wires and bars that are essential in construction and industrial machinery and is the world’s third most widely used metal, after iron and aluminium.

The majority of mines around the world produce copper concentrations between 24 to 40 per cent.

Trifett said having a higher concentrate percentage not only increases its monetary value but also simplifies the smelting process. “We have the potential to take this technology and apply it to our other operations in Australia and also other mines overseas as well,” he said. “We hope it will give us a competitive advantage to develop projects that would not otherwise have been able to be developed at the moment

strand at the University of South Australia’s Future Industries Institute Bill Skinner, who said hydromet would help transform the industry. “There’s an added advantage to hydromet – when they target iron, other impurities come out along with it, uranium and others,” he said. “Having any elevated level of radioactive material in the concentrate is not very good.

Hydromet produces a more valuable concentrate, reduces the carbon footprint, and removes impurities for subsequent processing.

“The Southeast Asian market particularly is highly technological. There is copper in just about everything; computers, TVs, air conditioners. Most of the production is coming out of China, Taiwan and Southeast Asia. Having this technology does make South Australia a more attractive source.”

Australia has about 6 per cent of the world’s economic copper resources and is ranked third after Chile (25 per cent) and the USA (16 per cent). South Australia has almost 70 per cent of Australia’s copper resources and is home to a number of longlife deposits, including Olympic Dam, the fourth largest copper resource in the world.

Brazilian company patents dry iron ore processing method

B

razilian company New Steel S/A has just patented, in Brazil and the United States, the first fully dry iron ore tailing processing method in the world. In times of water crisis and declining iron ore prices, the New Steel technique does not use a single drop of water, while traditional methods consume at least one thousand litres per ton of iron ore.

The technology has been proven to be excellent for the environment and economically sustainable as well. The method is designed to transform mining tailings — with low iron content and no commercial value — into an economically

conscientous and clean way possible.”

The Brazilian Institute of Industrial Property (INPI) immediately recognized the sustainability of the technology, ranking its patent application as a Green Patent and, in record time, it granted the definitive Letters Patent due to its unique inventiveness. Overseas, the patent has also been granted in the United States and is being processed in 26 other countries.

International recognition has come in other forms as well.

In 2015, New Steel won the international Platts Global Metals Awards, considered the “Oscar” of mining, in the innovation

“The only technology available to raise the content of very fine iron ore particles was flotation, but flotation is water-intensive and not economically sustainable in the current pricing scenario” feasible product, with high iron content and low contaminants.

“Before this invention, the only technology available to raise the content of very fine iron ore particles was flotation,” says Gustavo Emina, CEO of New Steel, “but flotation is waterintensive and is not economically sustainable in the current pricing scenario, making any new project unfeasible, as it demands high spending. In this scenario of retraction, new technologies find space and earn a well-established position.

We are partners of mining companies, as we ensure economic return while guaranteeing that they are operating in the most

category.

The new technology has been tested in Brazil since 2010, with New Steel’s operation of the first experimental dryprocessing plant in Minas Gerais. The test results confirmed the competitiveness of the method in terms of product quality and operating costs, which led the company to sign long-term contracts with the largest mining companies in the world. New plants are in the process of getting environmental licenses in Brazil. In the USA, negotiations to implement the new technology are underway.

Mining machine crushes comminution costs

A

n energy efficient mining machine is using mineral waste products to create a more environmentally friendly cement product. South Australian company IMP technologies (IMPTEC) has developed a super fine crusher that reduces comminution costs. The company is currently trialling a semi-commercial unit at Hallett Concrete in the South Australian capital, Adelaide, where the machine is being used to turn the waste from black sand or iron sand into a replacement for Portland cement.

IMPTEC director John Doherty said the crusher was a gamechanging invention that could eventually be at the forefront of the industry. “What we’re involved in is reducing the amount of energy, which is usually electrical, and the cost of media. You can also include lower maintenance costs because it’s just one machine,” he said. “The energy density of the crusher is greater than other machines and reduces around 30 per cent of energy costs.”

Comminution is the essential process of converting minerals into cement, more commonly Portland cement, a known producer of a number of greenhouse gases. It also accounts

“The energy density of the crusher is greater than other machines and reduces around 30 per cent of energy costs”

•

for almost 40 per cent of total mining costs and three per cent of the world’s energy consumption, prompting the search for a more efficient solution.

Conventional methods include breaking down large rocks to a few centimetres, crushing them further to fit into a ball mill, and grinding the minerals with the help of media and water till the material comes out in slurry form.

The new machine shortens the process by merging the second and third stage. It is unique because it also able to run the process dry and without the use of media. Doherty said the company plans to produce a fully commercial product by the end of the year. “Our semi-commercial unit takes in orders of two tonnes per hour,” he said. “If it approves itself over the next few months, it would be good. We’re looking at scaling up to 100 tonnes per hour.”

The transformation of black sand or granulated slag into cement is a world first. In April IMPTEC was awarded the Statewide Super Innovation in Resources Award for its super fine crusher at the inaugural South Australian Resources Industry Awards. The judging panel included the leader of the Minerals and Energy strand at the University of South Australia’s Future Industries Institute Bill Skinner, who said that as good deposits of high-grade minerals diminish, the need to grind more material finer was vital. “Energy consumption is going to go up if we are trying to keep up with what is needed in terms of metals. So anything that can reduce the footprint of an operating plant is going to be good,” he said.

“Portland cement is very energy intensive to produce and produces a lot of CO2 in the process. If you are using something that is actually a waste product, that is what you want.

This particular technology offers much reduced energy consumption.

Up scaling it is a challenge that needs to be overcome.”

What Puritech builds...

Nickel Laterite Nickel is a hard, silver white metal. It is mainly used in the manufacturing of stainless steel, steel alloys and superalloys.

Nickel laterite can be found in large amounts in the tropics and comprises 73% of the world nickel resources.

Nickel - Cobalt Separation A 200 m3/h Ni/Co Separation plant has been designed and installed in Africa by Puritech.

By using a split elution, the Nickel is separated from the Cobalt stream. A double or triple adsorption zone allows removing the desired metal almost completely.

Zinc Recovery The Zinc chloride can be removed from pickling acid. ZnCl2 will form a stable complex which is removed by anion resin.

The resin is afterwards eluted with water.

Uranium & Rare Earth Applications Hydrometallurgy is used more and more as the first choice to recover precious metals.

Some of the applications are: Uranium Lithium Rhenium Germanium Gold & silver ● ● ● ● ●

ll machines experience wear with use, especially pivots. Over time, the bores of the pivot become oval, affecting stability and safety. Repairs are expensive, time-consuming and are necessary multiple times over the life of a machine when using line boring and welding. To help customers save time and money, many heavy machinery dealers, such as SMS Equipment in Canada, have recommended the ExpanderÂŽSystem rather than the old traditional repair method.

Once the Expander®System sleeves expand, they are locked securely in place, even if the holes are worn oval. This permanently eliminates any further wear in the pivot lug ears, therefore extending the life of the bushings or bearings.

The Expander®System consists of an axle or pin body that is tapered at both ends, expansion sleeves, tension washers and fastening elements. The System installs directly into the worn pivot and once the fasteners are tightened, the washers push the sleeves up the tapered ends of the axle.

“Customers who use the Expander®System experience significantly increased productivity through reduced downtime,” said Scott Muir, SMS Equipment Manager, Product Support Sales. “For example, we had one customer running multiple mining trucks all day, every day, putting a large number of hours on the trucks in a relatively short time. That wears out the pivots quickly. Each truck has 18 pivots and changing those out is an extensive process.”

A Canadian company headquartered in Vancouver, British Columbia, Goldcorp employs more than 15,000 people worldwide, all sharing the company-wide commitment to responsible mining that is at the core of every business decision. Everyone, from senior management to the work crews at each of the company’s operations, strives to conduct their business to ensure lasting social progress and economic growth for all stakeholders throughout the life of a Goldcorp mine, and well beyond.

Goldcorp is committed to being a responsible steward of the environment and to maintaining the highest health and safety standards possible. It is a tireless advocate of human rights and maintains a principled, conscientious approach to corporate citizenship.

Goldcorp refers to its approach as ‘Together, Creating Sustainable Value’. Its programs are designed as catalysts for positive, lasting contributions in the communities where it does business, while working in partnership with host governments, indigenous groups, non-governmental organizations, contractors and suppliers.

The Red Lake Mine is one of the largest gold mines in Canada, and indeed the world. Located in one of the world’s most prolific gold districts, approximately 230 kilometres northwest of Dryden, Ontario, Goldcorp’s active mining operation covers approximately 2,335 hectares and is accessible by Highway 105, which heads north from the Trans-Canada Highway.

Daily commercial air services connect the numerous local communities to both Thunder Bay and Winnipeg.

Gold was first discovered in the Red Lake area in 1926. In 1995 Goldcorp discovered the world’s richest grade gold ore (two troy ounces of gold per metric ton) at its Red Lake Mine.

In 2015, gold production weighed in at 375,700 ounces. Recent investments in infrastructure and development have positioned this renowned mine for many more years of long-term sustainable production.

Underground mining at Red Lake uses three mining methods for maximum ore extraction: overhand cut and fill (OCF), underhand cut and fill (UFC), and long hole (LH). The highgrade zone, which primarily consists of a narrow vein system, is mined at the rate of 450 tonnes per day with an average grade of over 45 grams per tonne (1.3 ounces per tonne). The high-grade mineralization and complex geometry of the ore body require specialized operations expertise. Innovative mining techniques have improved efficiency, such as a wet shotcrete system, the use of larger trucks, use of electric man carriers and a portable diamond drill mounted on a jumbo carrier.

The operation is supported by two mill-processing facilities, providing a total milling capacity of 3,100 tonnes per day, including crushing, processing and pastefill plants. The processing plant’s operations consist of grinding, gravity concentrating, leaching, carbon-in-pulp (CIP), carbon elution •

and reactivation, electrowinning, bullion smelting/refining and cyanide destruction, flotation and concentrate handling —all of which are required to recover the gold in Red Lake’s ore types.

The Cochenour/Bruce Channel deposit is key to plans for future consolidation. The work on enlarging and upgrading the existing Cochenour shaft has been completed and a 6.0-kilometre haulage drift now connects the existing Red Lake underground infrastructure with Cochenour. The haulage drift will enable the efficient hauling of Cochenour/Bruce Channel ore to the Campbell mine for processing at the existing mill.

The drift also opens up exploration of over six kilometers of untested ground in one of the world’s richest gold districts.

The focus at Red Lake in 2016 is on asset optimization and cost reduction efforts. Continued transition to mechanized mining, bulk mining and material movement automation is expected to result in lower grades and lower mining costs.

“Éléonore is a major new mine located in an exciting goldproducing district: the James Bay region of Québec” Exploration in 2016 will continue to focus on the highgrade HG Young deposit. A key priority is the evaluation of underground development options to better assess the continuity of the mineralization at depth. Exploration will also continue in the HGZ at depth and on further testing of high grade zone deep offsets.

Gold mining is the primary industry in the municipality of Red Lake, and Goldcorp is central to many local developments and initiatives. The mining operation and its local workforce have an enormous economic effect on the area and its businesses, and Goldcorp supports a wide range of local activities related to education, health, community development, arts and culture.

Commercial production was declared on 1 April 2015, and by the end of the year, gold production totalled 268,100 ounces.

Through 2016, a conservative ramp-up schedule at Éléonore is expected to lead to gold production of between 250,000 and 280,000 ounces. Mine throughput is expected to average 4,900 tonnes per day from four production horizons following the depletion of the pre-production stockpile at the end of 2015.

The focus in 2016 is on increasing underground mining rates, mill throughput and improved dilution through adjustment of stope design. The production shaft is expected to be operational by the end of 2016, eliminating the need to truck or hoist ore through the exploration shaft. Drilling in 2016 will continue to target the 494 zone for reserve replacement and test the deep projection of the centre and southern ore bodies and the 494 zone.

Following several years of constructive discussions, the Cree Nation of Wemindji, the Grand Council of the Crees (Eeyou Istchee) and the Cree Regional Authority entered into a binding collaboration agreement with the Éléonore project.

The focus at Porcupine in 2016 is on asset optimization and cost reduction efforts. Current market conditions and operational challenges associated with aging infrastructure have led to the permanent closure of the Dome underground mine, effective in mid-2016. Mining operations at the Hollinger open pit, Hoyle Pond underground mine and processing plant will be optimized in order to sustain lowercost, profitable production.

The Hoyle Pond underground mine is accessed by decline and by a shaft. Mining methods currently employed are mechanized cut and fill and longhole. Extracted ore is transported via trucks and orepasses to the winze for hoisting.

The winze configuration allows for mining to approximately the 2,600m horizon, currently the mining horizon is 1,540m.

Gold is recovered using a combination of gravity concentration and cyanidation techniques. The circuit consists of primary, secondary and tertiary crushing, rod/ball mill grinding, gravity concentration, cyanide leaching, carbon-in-pulp gold recovery, stripping, electro winning and refining.

A key target of 2016 drilling is on the extensions of the S vein and of the newly-discovered XMS Vein near the 1600-meter level at Hoyle Pond.

Peñasquito is Mexico’s largest gold producer, consisting of two open pits - Peñasco and Chile Colorado - containing gold, silver, lead and zinc. The pyrite leach plant (“PLP”) project at Peñasquito envisages leaching a pyrite concentrate from the zinc flotation circuit tails to recover gold and silver that would otherwise report to the tailings facility at Peñasquito. An investment decision on PLP is expected by mid-2016, which if approved, is expected to be in production by the end of 2018. Peñasquito is an open-pit mine that employs flotationand-grinding processing, in two 50,000-tonne/day sulphide processing lines and a 30,000-tonne/day, high pressure grinding roll (HPGR) circuit.

Ore is extracted from two main zones in the mine: the PQ Deeps and the Lynx zone, with minor input from the Esker and Moose zones. Exploration drilling continues to expand the northern extent of the PQ Deeps and explore the Upper Lynx area, while looking for new ore sources to the west of the existing workings. Musselwhite’s processing includes crushing, grinding, leaching by cyanidation, carbon in pulp recovery and electrowinning, to achieve an overall recovery of approximately 96 percent.

A key target of 2016 exploration efforts will be extending the West Limb, where six mineralized horizons have been established. Exploration in 2016 will also follow-up on the Upper Lynx zone where two mineral horizons are both open to the north for further expansion.

The Los Filos operation consists of two open-pit mines – Los Filos and El Bermejal – and one underground mine. The openpit operation began commercial production in January 2008.

Gold production at Los Filos in 2015 totaled 272,900 ounces.

During 2015, Los Filos commenced a study to perform a detailed assessment of its operating options, including the update of the block model with additional drill data. The study was completed in the fourth quarter of 2015 and the findings were incorporated into an updated Los Filos life of mine plan.

As a result of these findings and the change in long-term metal price assumptions, recoverable ounces and the associated future after-tax cash flows decreased which resulted in a reduction of the estimated recoverable value of Los Filos and a shortened mine life.

The open-pit and underground mines share processing

facilities, and the ore is processed with Static Heap Leaching.

Marlin – Guatemala

Marlin mine has been in production since late 2005, operating as both an open pit and underground mine. The mine produced its one-millionth ounce of gold in 2010. Open pit operations ceased in early 2012 as the final, higher-grade portion of the open pit was mined, and the mine is now an underground operation only, but successful exploration activities in the area indicate the potential for extending the life of this highly productive mine.

In 2015, the mine produced 168,600 ounces of gold. Until 2012, Marlin’s open pit operation employed a conventional loader/truck cycle, producing approximately 25,000 total tonnes per day. Underground operations employ mechanized cut-and-fill and long hole stoping mining, with underground loading equipment feeding haul trucks that transport the ore to the surface via ramps. Production from underground operations is now roughly 3,200 ore tonnes per day. Ore is processed in a conventional crushing, grinding and milling circuit. Marlin also has a tailing storage facility, a waste rock storage area and various ancillary installations. Since 2012, a filter plant was commissioned to dry the tailings from the mill.

The dry tailings are being used to backfill the pit.

Any kind of mining carries with it risk, financial and human.

Goldcorp recently experienced a serious accident at its Marlin mine, when a worker became trapped underground after an unexpected fall-of-rock. Goldcorp immediately dispatched

first responders, but tragically, rescue efforts were unsuccessful.

The company is fully cooperating with relevant authorities and mining operations at Marlin remain suspended while the investigation is underway. The company is committed to reviewing safety procedures to ensure safety remains the highest priority across all of its operations.

Cerro Negro is a high-grade gold mine located in the Santa Cruz province of Argentina. It contains several high-grade vein structures, including the Mariana Central, Mariana Norte, San Marcos and Eureka. Cerro Negro was acquired in 2010 and since then the gold reserves and resources have nearly doubled, and new discoveries support expectations that Cerro Negro will be a long-lived, high quality asset with low production costs. Cerro Negro’s ideal physical setting and easily accessible veins will result in near-term, cash flow-accretive gold production. The property contains a large, very prospective land package, with a rich network of near-surface gold veins.

“As an advanced exploration project, Cochenour is an important part of Goldcorp’s future plans in the Red Lake district” An advance exploration permit is expected to be received by late 2016. The permit would allow for the construction of a ramp into the deposit and the extraction of a 30,000 tonne bulk sample and provide an underground platform for exploration drilling of a deposit that still remains open at depth and laterally.

On 24 November 2015, Goldcorp and Teck Resources Limited announced the completion of the previously announced agreement to combine their respective El Morro and Relincho projects into a 50/50 joint venture with the interim name of Project Corridor. “Combining these two neighbouring assets is a common sense approach that allows us to consolidate infrastructure to reduce costs, reduce the environmental footprint and provide greater returns over either standalone project,” said Don Lindsay, President and CEO of Teck.

“Through Project Corridor, we will work to establish meaningful relationships with the community, indigenous peoples and other stakeholders that will help guide the project’s development and create greater value for all parties.”

“The combination of El Morro and Relincho is consistent with our focus on maximizing value from our asset portfolio,” said Chuck Jeannes, President and CEO of Goldcorp. “We now have an improved development approach that we expect to significantly decrease initial capital requirements and increase financial returns, while ensuring the project is developed in partnership with our neighbours, creating lasting benefits for residents in the region and our shareholders.”

The impact of mining continues long after a mine closes, and as mentioned above, so, too does the commitment of Goldcorp to the lives it affects. The San Martin mine in Central Honduras, approximately 90 kilometres north of the capital city of Tegucigalpa, is witness to that.

San Martin commenced reclamation and closure activities following the last full year of commercial production in 2007.

In 2008, Goldcorp donated the mine camp to the San Martin Foundation. Today, chickens, pigs and cattle are farmed on the 1,500 hectare former mine site, providing functioning ecosystems, sustainable jobs and skills training to the people of the Valle de Siria. The former camp facilities have been remodelled to become a hotel for ecotourism, complete with a pool, sports field, nature trails and a training centre for the community: a sustainable business that has created local jobs and new investment in the area.

Cochenour, Canada

An advanced exploration project, Cochenour is an important part of Goldcorp’s future plans in the Red Lake district. The focus during 2015 was on drilling and development to increase the level of confidence in the interpretation of the deposit.

Initial development since 2015 has shown deviations of the geology and structures from the initial interpretation. The primary target of 2016 exploration is gaining comfort in the Upper Main zone primary shoot through tight spaced drilling, ramping and development. A new program of drilling, sampling and test mining is expected to be designed by the middle of 2016.

Dos Santos International Goldcorp and Dos Santos International Partnering in Innovation at Los Filos Located in the Nukay mining district of central Guerrero State, Mexico, the Los Filos gold mining project is one of the largest openpit gold mines in the country. Los Filos is a heap leach operation.

The ore size is reduced at the crushing plant and then hauled to the valley where it is stacked on engineered pads. The ore is sprayed with a chemical solution that extracts and absorbs the gold as it trickles through the ore. To regulate seepage rate, an agglomerate (cement) is mixed into the ore to optimize ore exposure to the leaching solution. Ultimately, the solution is directed to the plant where the gold is precipitated out.

n 2008, the Los Filos mine began operation of a new conveyor line from the mine crusher to the leach pads. The haulage path went down a mountain side to the leach pads that were built in the valley below. Rather than confronting the steep slope of the mountainside, a glory hole ore pass from the hill top was connected with a tunnel from the toe of the hill.

The glory hole served to store the ore. A feeder at the bottom then metered the material onto the tunnel conveyor that led to a rotary agglomerating drum. The agglomerating drum mixed the ore with the special powder. The ore mix was then conveyed to a spreading system on the leach pads.

That conveying system experienced material flow problems right from the start, especially during heavy rains. The sticky ore tended to plug up the ore pass. Geological instability ultimately collapsed the ore pass, putting the transport system out of service only four months into its operation.

This required a return to ore haulage entirely by trucks at a tremendous cost premium.

At that time M3 Engineering of Tucson, Arizona, USA, was contracted to develop a new conveying path to the leach pads. As they were aware of DSI Sandwich Belt High Angle Conveyors from previous exchanges, M3 found the perfect solution – a downhill DSI Sandwich Belt High Angle Conveyor that would begin at the top of the collapsed ore pass, then run down the hill to the toe at the tunnel exit. This would allow continued use of the other existing conveyors. After the Goldcorp professionals did their due diligence, including a visit to the Dos Santos Sandwich Belt High Angle conveyors at Empire Mine, in Palmer, Michigan, USA, they decided to buy a DSI downhill high angle conveyor. The order was booked in February of 2009. That system, depicted in figure 1, was to have impressive characteristics – 1000 t/h design rate with a vertical drop distance of 113 meters. The 1220 mm (48”) wide belts would travel 311 meters at 2.5 m/s along the 37 degrees inclined slope to discharge over an ore storage pile at the bottom of the hill. Twin 200 horsepower drives would operate as generators under load, feeding power into the mine grid.

Concerns with geological instability along the high angle path remained. While DSI was beginning the engineering of the new downhill Sandwich Belt Conveyor, Goldcorp geologists continued investigations into the stability of the mountain-side.

After less than a month in engineering, Goldcorp declared that the hill was not sufficiently stable and they cancelled the DSI high angle conveyor order.

M3 immediately began work on developing an overland conveying path to the leach pads by following the already developed truck haulage ramps. Because DSI already had the high angle conveyor order, they petitioned Goldcorp to convert that into an order for a DSI overland conveyor system.

Goldcorp insisted that the new haulage system must go out to competitive bidding as it was required by company policy.

They encouraged Dos Santos International to make their best offering for the new overland conveyor system. After the path was developed, an inquiry was sent out for bid to qualified companies. The inquiry concept included ten conveyor flights. The first three were elevating flights and the remainder were downhill and decisively regenerative. Whereas all other conveyors were of 914mm (36”) belt width the first downhill flight was a slow moving 1220mm (48”) wide conveyor with five trips along the length. This was a Goldcorp innovation that made the wide, slow, tripped conveyor an agglomerator, eliminating the need for an agglomerating drum. The special powder would be added to the ore at the end of the last elevating conveyor. Then, the mix would tumble through the •

multiple trips and transfers en route to the leach pads.

Dos Santos International made its best effort in proposing the DSI overland conveying system including improvements to the overland concept in the inquiry. A modular system of terminals and table type modular intermediate structure was developed for best economics and versatility. Additionally, the possibility of further improvements was considered by amalgamating sequential flights with horizontal curves.

Because time did not allow development of this additional advantage in the short time allowed for quoting, the proposal was submitted for the ten flight system. The Dos Santos International proposal included two important commitments solely for the customer’s benefit: 1.

DSI would maximize use of the conveying equipment

and structure, already at the mine, from the collapsed

and abandoned through-the-hill conveying system.

2.

DSI would investigate the amalgamation of sequential

flights with horizontal curves as the first order of

business in engineering. The favorable findings would

be implemented and the savings credited to Goldcorp.

In June, Dos Santos International was awarded the overland conveyor system as a ten flight system. Both commitments were fulfilled, reaping substantial cost savings to Goldcorp. In the former case, the first conveyor (TB25 shown in figures 2 and 3) was engineered to use all existing conveyor equipment and structure. Though the arrangement is entirely new, the equipment and support steel are reused from the previous system. The head drive terminal is the only portion of TB25 that contains new equipment. New steel at the support bents, minor framing, and a new discharge chute make up only a small portion of the total structure.

In the latter case, investigation over the first two weeks determined that three sets of two sequential flights could be 76

amalgamated for a significant savings to the customer. The last two elevating flights were thus amalgamated into one horizontally curving conveyor (TB26 shown in figures 2, 3 and the cover image) and the four downhill flights after the agglomerating conveyor were amalgamated into two horizontally curving conveyors (TB28 shown in figures 2 and 6 and TB29 shown in figure 2). Thus the system was reduced to a seven flight system and a credit of US$180,000.00 was issued to Goldcorp, reflecting the savings in the DSI engineering and supply. Of course, this generated additional capital savings in construction and recurring savings in both power consumption and wear and tear.

The overland conveying path is predominantly downhill.

While this presents the normal controlled starting and stopping problems, it also presents great savings opportunities.

The downhill flights are decisively regenerative. The drive motors, now generators when running loaded, feed electrical

These carefully engineered conveyors are equipped with variable frequency drives to ensure operation at maximum efficiency.

The Los Filos mine has been Mexico’s largest gold producer since 2009, with 5,470,000 ounces of proven and probable reserves, 2,200,000 ounces measured and 3,820,000 ounces inferred as of December 2010. The Dos Santos International overland conveyor system went into operation in 2009. This innovative and productive system has operated reliably and efficiently for the last seven years delivering significant savings to Goldcorp when compared to the previous truck-only haulage system. It will continue to deliver success for many years to come. Dos Santos International is pleased to be a part of the success of Goldcorp at the Los Filos Mine.

A

s we move toward a circular economy based on virtually no waste, with raw materials continually recycled and reused, the crucial role water plays is top of mind for corporate leaders across the globe. Shareholders expect companies to show they are pursuing strategies to minimize operational and environmental risk associated with their water usage.

Balancing the increasing environmental, regulatory and social pressures with the high energy and water footprint of a mine operation is an ever-evolving challenge that directly impacts profitability. Through comprehensive water processing technologies that facilitate the reuse of mine water and promote asset protection of equipment and pipelines, companies can potentially capture more value from mining operations while striving to reduce their water footprint and reliance on freshwater resources.

Comprehensive mine water operations can be categorized into three strategies—water treatment, asset protection and operations optimization—that work together to facilitate mine water reuse. Water treatment technologies, including filtration, reverse osmosis and ion exchange, allow mine water to be processed from some of the most challenging sources and can help reduce net water consumption and treat wastewater for reuse. The application of microbial control and antiscalants on assets like equipment and pipelines can help reduce downtime, lower maintenance and add longevity to these assets. These efforts can directly address the sustainability, compliance and efficiency challenges facing mining operations today.

Treating the water

Modern water treatment strategies depend on several factors including the type of ore being mined, the chemicals used in the mineral preparation and metal extraction processes, the climate, the life stage of the mine and its environmental management practices. Numerous technologies are available today to address all of the mining industry’s water management needs, including water quality, expanded water sourcing, water recycling and remediation, all while facilitating sustainable, cost-effective operations.

“Mining is ranked as the world’s second largest industrial user of water” Ion exchange, reverse osmosis (RO), nanofiltration and ultrafiltration (UF) serve as core technologies for purifying and recovering water to directly address increasing pressures from environmental regulations and sustainability goals.

A coal mine in South Africa turned to Dow UF technology as a pretreatment to RO when conventional sand filters were found ineffective for treating wastewater for reuse. Dow’s UF and RO technologies help treat the coal mining wastewater for operational reuse, helping reduce overall costs and helping to avoid negative impact to nearby at-risk water sources.

Dow UF technology and Dow FILMTEC™ RO elements reject particles, colloids, suspended solids, oxidized Fe/Mn and microorganisms from the wastewater, which is then transported to a nearby power station where it is demineralized with ion exchange resin technology and used as boiler feed makeup water. These technologies help provide higher and more consistent filtrate quality, increased feed and turbidity 82

• Water Management tolerance, lower silt load and less frequent clean in place (CIP), directly lowering chemical use and extending the life of the RO membranes. This highly automated operation was found to lower maintenance and reduce the mine’s water footprint.

Protecting assets Pipes are susceptible to degradation from scale buildup as a result of mineral precipitate that forms as water flows. In mineral processing operations in particular, pipes and equipment are susceptible to the insoluble salts—calcium carbonate, calcium sulfate, magnesium and silicate—that drop out of process water and solutions. These salts build up on equipment and pipes to create scale, which can restrict pipe flow and ultimately require downtime for cleaning. Antiscaling technologies can address both organic and inorganic flow assurance challenges—including prevention of build-up before it occurs and removing build-up when it does occur. Inhibitors and dispersants help prevent scale from forming, while chelating agents remove and inhibit scale deposits.

In addition to scale build-up, microorganisms can grow just about anywhere water can be found. The resulting biofilm formation can then cause pipe and equipment corrosion due to microbiological induced corrosion (MIC), leading to leaks and impacting the flow of water. While microbial contamination is known to cause MIC in typical transmission pipelines of water and/or mineral slurries, most mining companies are unaware of how microbiological contamination hinders their operational efficiency, including product quality losses due to bacteria metabolites and impacts on mineral separation processes. To adhere to sustainability goals and regulations, it’s important that a microbial control program perform its job effectively, while doing no harm to people or the planet, and then ultimately go away - providing extended microbial control while resulting in minimal negative impact on the environment. Dow Microbial Control carries out advanced field diagnostics which identify contamination hot spots in a mining plant and recommends customized solutions using our Dow AQUCARTM Water Treatment Microbiocides portfolio, which can provide quick kill action as well as long term protection tailored to the needs of the process.

The power of ORE Mining is ranked as the second largest industrial user of water globally, and managing this use is critical for sustainability, and also efficiency. Dow Energy & Water Solutions’ rich history in the mining industry—coupled with its innovative advanced water treatment, antiscalant and microbial control technologies— helps increase water and energy efficiency to enable customers to extract more value. With the Power of ORE (Operational efficiency, Recovery enhancement, Environmental compliance), Dow brings a wide range of products and expertise to address a broad spectrum of mining, mineral processing and remediation challenges. Through integrated solutions, Dow can help deliver the right water quality to facilitate a reliable water supply while helping to maintain clear, efficient pipelines. By using filtration, ion exchange, and reverse osmosis technologies that can process even the most challenging mine water, integrating membrane installations that treat wastewater for reuse, and applying antiscalants and biocides that can help reduce downtime and add longevity to assets, a comprehensive water management program can increase mine efficiency and wastewater reuse, while decreasing downtime for cleaning and maintenance.

• Newmont Mining “Colonel William Boyce Thompson named the company Newmont after New York and his home state Montana”

A century of growth

Newmont has grown over the past century into the industry giant it is today. When mine promoter and financier Colonel William Boyce Thompson decided to create a company in 1916 to handle his larger private acquisitions – including oil and gas and mining interests – he named it the Newmont Company after New York, where he made his money, and Montana, where he grew up. The early portfolio included interests in coal, copper, lead and zinc. Newmont steadily grew by acquisition and diversification, often through joint ventures with other well-established companies. Renamed Newmont Mining Corporation in 1925, today Newmont’s portfolio includes significant operations in North America, South America, Asia, Australia and Africa.

Exploration and production

Searching for gold is a complex, scientific and time-intensive process. With odds of only one in 3,000 discoveries leading to mine development, and only 10 percent of the world’s gold

deposits containing enough gold to mine, exploration can be wearisome and expensive. While gold is found throughout the world at concentrations of between two and four parts per billion, mining companies need to discover areas that contain 2,000 to 3,000 parts per billion to be profitable. So how do Newmont’s exploration teams locate future large-scale projects?

The first step is prospecting, but with veins of gold typically spanning just a few feet in width, and curving along the Earth’s geography, it is extremely difficult to pinpoint an area of exploration among thousands of square miles of land.

Obviously, it makes sense to start in areas known to contain gold, but there are nearly 900 such locations in the world to choose from. Ideally, it is best to start looking in areas less explored, but Newmont also seeks exploration partners and/ or acquires junior mining companies to expedite the process.

Several methods are used to reduce the size of land to explore: • Evaluation of the land’s geology • Analysis of the geochemistry of soil sediment and water • Commissioning of airborne geophysics surveys to

record the electrical and magnetic current in the crust below.

Once a target area has been identified, and geological, geophysical and geochemical data indicate a high probability of a deposit, drilling is conducted. Drilling helps to evaluate the type and grade of minerals in the ore. Another way Newmont samples is through trenching, which hugs the surface and is carried out by backhoes or bulldozers. As crews drill, they mark the exact location and depth of each sample taken. Samples are then sent to an accredited lab, which identifies the type of minerals and grade of gold within them.

Once information is back from the lab, those findings are supplemented with geologic, geochemical and geophysical data. Understanding the local geology is a very important part of the process, both economically and environmentally. The geology affects mining, processing and the ways in which waste rock, tailings and water are managed. It is also an important aspect of rehabilitation plans.

Newmont’s 2016 attributable exploration budget is approximately $185 million. Of this amount, the company expects to spend about 45% in North America, 15% in South America, and the rest split between Asia Pacific, Africa and other locations. Of the total attributable exploration budget, Newmont expects to spend approximately 75% on near mine and brownfields exploration activities, with the balance allocated to greenfields programs.

Historically, Newmont focused its operations and exploration within North America, but the company’s success has inevitably led to global expansion and today Newmont •
