COMMITMENT TO A FIRST-CLASS SAFETY CULTURE

JIM BUCKLE General Superintendent PTRI Safety & Training

Redpath Indonesia is extremely proud of all safety and training accomplishments in the past 40 years. We continue to be committed to delivering a safe, high-quality product to our valued client.

Along with accomplishments, there have naturally also been challenges. One of the current challenges is the increasing number of new supervisors. Strong and effective supervision is essential for incident prevention, and Redpath’s Supervisory Coaching & Mentoring

Program addresses this need.

The Supervisory Coaching & Mentoring Program is created in accordance with the 5-point safety system. The program is intended to improve the quality of supervisor interaction so that an effective twoway interactivity can be created with workers.

Implementing a three-stage mentoring supervision program for all supervisors aims to achieve safe and effective production while developing exceptional leadership.

Another challenge revolves around hazards and risks associated with rigging knowledge and practices.

Previous on-site rigging training focused on large overhead cranes used in shop facilities. This setup did not meet the requirements for

To work at the PTFI project required more than your average level of endurance.

Now, Redpath’s safety training team utilizes the boom truck for practical training in a more realistic underground environment. This new practical session provides operators with clear and precise instructions on how to handle materials safely in an underground mine.

Throughout Redpath’s years in Indonesia, the company has continued its commitment to developing a world-class safety culture. As we continue to excel in this area, we acknowledge that this would not be possible without the support from our client. We look forward to many more years of collaboration with PTFI as we continue to grow our safety culture to the highest standards.

This client longevity is only possible because of our ability to deliver safe, on time, on budget service to our clients consistently over time.

This issue of the Advance is largely dedicated to Redpath’s longest-term project at PTFI in Indonesia, where we have worked continuously for the past forty years. Really!

The ability of our team at the PTFI project to adapt and respond to the changing needs of our client has been key to providing a high level of service. Our team has had to adapt to all manners of different ground conditions, equipment and methods over the years.

MIKE KELLY President, Redpath Raiseboring Limited

My first trip to the PTFI project in 1982 was an eye opener! They chose us to bore ventilation raises. The program went so well that PTFI decided to keep us.

From that first machine, the fleet of drills has grown to fifteen. We now have a world-class group of mining professionals who deliver the largest mass excavations and thousands of metres monthly of lateral development. Finance and HR ensure Ops can focus on the work!

ADAPTATION – CRITICAL TO REDPATH’S LONG-TERM SUCCESS

In 1982, Redpath was awarded a raiseboring contract which later expanded to include alimak raising, mine development as well as miscellaneous construction activities.

FANTASTIC TEAM EFFORT IN INDONESIA

SPECIAL THANK YOU

In 1982, Redpath arrived on site in Indonesia with a crew of ten and a single raisebore drill, the 82R-1242. That first contract marked the start of what would become Redpath’s largest and longest running project to date.

GRASBERG MINING DISTRICT

T Redpath’s involvement in the Grasberg Mining District is focused on the Grasberg Block Cave and the Deep Mill Level Zone.

he Grasberg Mining District houses one of the world’s largest copper and gold deposits.

The ore bodies were discovered in 1988, and are owned by FreeportMcMoRan Inc. (FCX) and Mining Industry Indonesia (MIND ID), which is owned by the Indonesian government. Freeport-McMoRan Inc. (FCX) operates the mining district.

The district is located within and around two main igneous intrusions; the Grasberg monzodiorite and the Ertsberg diorite. These open-pit and underground mines include Grasberg Open Pit, Grasberg Block Cave (GBC), Deep Ore Zone, Deep Mill Level Zone (DMLZ), and the Big Gossan Mine. The Deep Ore Zone (DOZ) ceased production in 2021 and Grasberg Open Pit in 2019. Mine development activities for the Kucing Liar deposit commenced in 2021.

GRASBERG BLOCK CAVE (GBC) The Grasberg Block Cave ore body is the same ore body which was mined from the surface in the Grasberg open pit.

The emphasis of Redpath’s involvement in GBC has shifted from development and construction of the mine, to managing those activities and the caving operations, while ramping up the mine to full production.

From lateral development, footprint construction, mine rehabilitation, mine service installation, massive excavation, to large-scale block cave production, the Redpath GBC team provides almost full turnkey mine contracting services to PTFI. The GBC Mine will be the largest block caving operation in the world when full production is reached.

PROJECT MASTERMINDS - PTRI

THE ACCOMPLISHMENTS OF THE PTRI TEAM WOULD NOT BE POSSIBLE WITHOUT THESE PROJECT MASTERMINDS.

“I started at the bottom and climbed to the top.”

NICKY HERAULT PTRI Operational Director

I was interested in the PTFI project while I was working in the Matagami Isle Dieu shaft sinking project in the 1989-90 era. I contacted the Ram Raising office* in Timmins indicating my interest. I received information that I was accepted while I was working in Timmins at the Kidd Creek shaft sink. I landed in Timika on July 14, 1991.

Back then, we flew through Cairns, Australia, on a privately chartered aircraft which, it was rumoured, had once belonged to Elvis Presley.

I was originally hired at the PTFI project as an Alimak miner with skills in shaft sinking and construction.

What are you most proud of when it comes to your involvement in this project?

My experience and knowledge were quickly put to the test with an abundance of work and projects to work on.

The project has been an opportunity to express my values, knowledge and beliefs. Not too often does a project give you enough flexibility and freedom to influence its direction. I have been fortunate enough to be part of this project’s pioneering era and to manage its core values throughout the years. It’s very much a reflection of who I am as a person and a Redpath employee.

What has this project meant for you personally?

The project for me is a source of challenges and a sense of acceptance of accomplishments. It offers the opportunity to influence people in a positive and constructive manner.

I’m also proud of the fact that I started at the bottom and climbed to the top, while

developing and maintaining a worldclass team able to meet today’s difficult challenges with such a large operation.

What are the top three things that are key for the project’s success and why are they important?

Our industry continues to develop and meet the needs of a changing world.

We need to ensure that our employees are also capable of meeting these changes. Future leaders will need to be more flexible and responsive in order to be successful.

1. To lead by example. All team leaders need to demonstrate by example. This is how we positively influence our employees.

2. To communicate openly. We need to be able to have clear, honest discussions with the workforce. It’s important to share the expectations and the desired outcomes.

3. To listen and acknowledge your employees. This does not necessarily mean that you fix all their problems, but it does mean that you understand their challenges and values.

What has this project meant for you personally?

I have been involved in many challenging projects within Redpath Indonesia; one of them is the Grasberg Block Cave (GBC) project.

The GBC project marked, no doubt, my life here. In my mind, simply nothing compares to it. It is the cornerstone of our company - a project meant to become one of the largest block cave mines in the world - something all of us should be proud of. My time with Redpath is one of the most exciting, challenging and definitely mind-blowing experiences I could ever have dreamt of. This mix of nationalities, experiences, skills, languages and even beliefs, all working together as a team, makes this place unique. To witness the company collaborate with the Indigenous Peoples, the Papuans, growing together, is something to be proud of as well. I remember once reading the slogan “Unity in diversity”; what a living example we

all give to this nation and to the world here at site.

What are you most proud of when it comes to your involvement in this project?

I’ve had the opportunity to orchestrate and integrate extraordinary teams within Redpath GBC, providing unparalleled solutions for project execution, from feasibility studies to reality. As an integral part of the GBC Mine, Redpath successfully tackles all of the project's scope, ranging from development and construction, to the production phase - on schedule, SAFELY.

IVAN AGUSTIAN How and when did you get involved in the project?

I started working on the project in August 2005 as a fresh graduate with some experience from a small underground coal mine. Unlike the typical hiring process at the time, I only had phone and online interviews with Redpath. Coming into one of the largest mines in the world and joining a reputable international contractor really pumped my adrenaline. I started working as a junior engineer at Redpath’s core operations projects at the Deep Ore Zone (DOZ) Mine.

Redpath’s reputation and extensive experience on-site has made it a go-to contractor that can respond to any challenge, anywhere, anytime!

What are the top three things that are key for the project’s success and why are they important?

1. Willing to tackle any challenge, SAFELY. Challenge is always an opportunity. A challenging project encourages us to go beyond the obvious, use our resources efficiently, think outside the box, and narrow in on the project’s purpose. All these behaviours are necessary to continue to challenge ourselves to find a better, safer way, and we shouldn’t be afraid to be the first.

When that environment rapidly changes, staying relevant helps us adapt to the

What has this project meant for you personally?

This project is part of my life, even after I left the mine site. I am closely attached to the project. This is where I have learned both technical and non-technical aspects of work and life. It has been a great journey to continuously learn from talented and passionate people within the project.

What are you most proud of when it comes to your involvement in this project?

There are multiple stages in my life and career to be proud of, and most of them are associated with the ability to overcome major challenges. My most proud moments are when I see team members, whom I have worked with, grow and then successfully step up to higher levels of responsibility.

new circumstances, enabling us to be the leader in the industry.

3. Plan for the best, prepare for the worst and communicate it! The best planning takes time as we need to consider every possibility in advance. The more prepared we are, the better we’ll be able to respond and keep the project safe, sustainable and secure.

By communicating the plan and project status consistently, we ensure that team members and the client are aligned on project goals and that everyone understands exactly what’s expected of them.

Consistent communication contributes to the development of trust, resulting in enhanced collaboration, from project inception to completion.

Ivan Agustian and Bruce Mennie have worked together on the PTFI project since 2005.

What are the top three things that are key for the project’s success and why are they important?

The first one is planning. This is a key mantra that leads to effectiveness. The second one is collaboration within your team, across departments and, more importantly, with the client. It is almost impossible to expect a successful project without collaboration and effective communication with stakeholders.

The third one is continuous improvement. This is essential for survival in the industry. Our presence at the PTFI project for 40 years shows that we have done our best to continuously improve and create a desire in the industry for our continuing services.

Redpath employees supported the island of Lombok in West Nusa Tenggara, Indonesia, after the 2019 earthquake.

Redpath continually strives to train and advance the local Papuan workforce, and to provide opportunity for career development within Redpath. One recent example is Benny Diwitau, who was promoted to Superintendent for the Deep Mill Level Zone Mine (DMLZ) lateral development project.

Benny joined Redpath in 2007 as an Alimak miner. He later became a shaft miner, then tunnel miner and supervisor before his recent promotion.

PT Redpath Indonesia achieved another milestone in November of 2022, when the first ever Redbore 90 EX large diameter raisebore was successfully commissioned. The commissioning followed the large diameter contract awarded to PTRI earlier in the year.

The historic achievement was the culmination of a very demanding and concerted effort by Redpath’s teams in Canada, Australia, Indonesia and South Africa.

The Redbore 90 EX provides the ability to establish 5.0 m and 6.0 m diameter raises over distances more than 300 m in length, meeting the client’s expansion requirements in both ventilation and ore movement.

PTRI currently maintains and operates 12 raisebore machines at PTFI, drilling out a variety of holes for different applications ranging from drain holes of various diameters, intake ventilation raises, slot raises, exhaust raises, and ore passes. The addition of the Redbore 90 EX makes PTFI the mine with the single largest Redpath raisebore fleet at one site.

Hasudungan and Franky are just one example of many Redpath father-son miners who continue to strengthen and extend their family bond in the workplace, building a path for a better life for their families.
