Perenti Limited’s underground mining business, Barminco, has been awarded a new contract for the provision of mining services at Regis Resources Limited’s Duketon Operations (including Rosemont and Garden Well underground mines) in the Goldfields region of Western Australia.

The alliance style agreement comes with a contract value of A$393 million ($255 million) and is based on initial three-year term, commencing April 1, 2024.

As part of the pact, Barminco is due to carry out underground development, production and support services at the operations.

Regis recently opened the Balkau Decline at its Garden Well South underground mine, which is an underground extension of the Garden Well open-pit mine: a key production source at Regis’ Duketon gold project.

Rosemont, meanwhile, includes the Rosemont open pit and underground mine, as well as Baneygo open pit. The Rosemont and associated surface deposits are mined using conventional open-pit mining truck and shovel methods. The Rosemont underground produces approximately 600,000 t/y and is mined using mechanised open stoping.

Mark Norwell, Managing Director & Chief Executive Officer of Perenti, said: “We’re very pleased to continue our partnership with Regis Resources at the Duketon Operations where Barminco has been providing value to our
client through both development and production works since February 2019. This award adds Australian based underground earnings to our portfolio, which is aligned with the ongoing delivery of our strategy.”

Gabrielle Iwanow, President of Contract Mining, said, “Our people are at the heart of our success and their dedication, innovative thinking and highly skilled efforts have again resulted in the award of a significant contract with the third largest Australian gold producer on the ASX, at a great mine that is located right here in Western Australia. We are proud to continue partnering with Regis Resources as we embark on this alliance style contract to further deliver on our purpose of creating enduring value and certainty.”

Perenti says it has secured new work and contract extensions with the likes of Regis Resources, BHP Mitsubishi Alliance (BMA) and Catalyst Metal in Australia representing nearly A$150 million ($97 million) of revenue across its 2024 and 2025 financial years.

It has booked a A$70 million, six-month contract for the continuation of underground development and production works at the Regis Resources Garden Well and Rosemont underground gold mines. Barminco and Regis continue to progress collaboratively towards further and material contract extensions at these two mines, it says.

It has also sealed a A$27 million, 24-month contract for exploration surface drilling services at the BHP Mitsubishi Alliance in Queensland, while a A$14 million, 24-month contract has been awarded for underground diamond drilling works at Catalyst Metal’s Plutonic underground gold mine in Western Australia, subject to finalisation of contract terms.

Furthermore, AUMS (through UMA, a joint venture with Rocksure International) received a limited notice to proceed related to the initial underground development works at the Newmont Akyem underground gold mine in Ghana. The finalisation of contractual negotiations continues, however, once finalised it is forecast that the contract could represent circa-A$32 million of revenue over an initial term of 11 months, with a capital structure that is likely to be similar to that adopted for Newmont’s Subika project.

Mark Norwell, Managing Director & Chief Executive Officer of Perenti, said: “The award of these contracts and the limited notice to proceed across both our underground and surface mining businesses demonstrates the diversity of our service offering and the strength of the relationships we share with our clients. Collectively these three contracts and the limited notice to proceed represent nearly A$150 million of revenue across FY2024 and into FY2025 and come after the recent announcement in which Perenti secured circa-A$360 million of revenue at the Sandfire Resources A4 project in Botswana.”

Barminco says it is further extending its relationship with Regis Resources Ltd, securing a A$70 million ($45 million), six-month extension at the gold miner’s Rosemont and Garden Well operations in Western Australia.

With both gold mines in close proximity, it allows Barminco to continue to be agile with resourcing and equipment to provide comprehensive underground mining services to our client, it says.

Regis recently opened the Balkau Decline at its Garden Well South underground mine, which is an underground extension of the Garden Well open-pit mine: a key production source at Regis’ Duketon gold project, located in the Goldfields region.

Rosemont, meanwhile, includes the Rosemont open pit and underground mine, as well as Baneygo open pit. The Rosemont and associated surface deposits are mined using conventional open-pit mining truck and shovel methods. The Rosemont underground produces approximately 600,000 t/y and is mined using mechanised open stoping.

Regis Resources opens Balkau Decline at Garden Well South underground mine

Regis Resources Ltd has officially opened the Balkau Decline at its Garden Well South underground mine, in Western Australia, named after Regis General Manager of Exploration, Jens Balkau, who passed away in 2021.

Garden Well South underground is an underground extension of the Garden Well open-pit mine, which is a key production source at Regis’ Duketon gold project, located in the Goldfields region of Western Australia.

The original Garden Well deposit was discovered as a “blind deposit” by the Regis exploration team led by Jens Balkau.

Balkau was one of the first and longest serving employees of Regis, joining in January 2006 as the General Manager of Exploration, and remaining in that role until February 2016 when he retired from full-time work. He remained a consultant to Regis before he passed away from a long-term illness in November 2021.

The Balkau Decline provides access to Regis’ second underground operation, located at Garden Well South, which commenced commercial production during May 2023. This is part of the mineralised system that extends for at least 1 km underneath the existing Garden Well open pits, which resulted from the original discovery by the team that Balkau led, Regis said.

This milestone is the culmination of more than two years of preparation, commitment and hard work from Regis teams with support from major mining services providers Barminco and MACA, it added.

Garden Well Underground will become a key part of the wider Duketon operations, which produced 356,000 oz of gold in the year ending June 30, 2021.

The official opening ceremony for the Balkau Decline was attended by Balkau’s family, local Traditional Owners as well as many former and current Regis employees, including Regis Chairman, James Mactier, and Managing Director and CEO, Jim Beyer.

Beyer said: “The official naming of the Balkau Decline yesterday reflects this positive evolution for the Garden Well operation, so it is fitting we name it after the man who led the initial discovery of Garden Well. Jens was a much-loved and valued colleague, friend and mentor to many at Regis. He led the exploration team for over a decade with enthusiasm and an abundant willingness to nurture the next generation of geologists.

“Jens is deeply missed, but his legacy will always be remembered at Regis.”

Pacific Energy to integrate more ‘clean energy’ into Tropicana gold operation

Pacific Energy says it has been awarded the contract to integrate 62 MW of clean energy into its existing 54 MW gas fired power system at the Tropicana gold mine, 330 km northeast of Kalgoorlie in Western Australia.

Tropicana is owned by AngloGold Ashanti Australia Ltd (70% and manager) and Regis Resources Ltd (30%).

The renewable expansion of the existing power system will be delivered under a 10-year build-own-operate agreement. When completed, the 116 MW power station will be the largest off-grid hybrid investment in the power provider’s portfolio, and, at time of contract, the largest off-grid gas-wind-solar-battery storage facility in the Australian resources sector, according to Pacific Energy.

The expansion will incorporate four 6 MW wind turbines, a 24 MW solar farm and a 14 MW battery storage system (BESS). The integrated power facility’s intelligent control system, which has been developed in-house by Pacific Energy, will optimise input from the high penetration renewable energy and storage technologies and allow the system to run hydrocarbons-free for extended periods of time, the company says.

Pacific Energy has designed the new system to support AngloGold Ashanti’s strategy of reducing its global net carbon emissions from energy use by 30% by 2030, as part of its roadmap to net-zero carbon emissions by 2050.

Overall, the renewables integration is expected to reduce Tropicana’s diesel and gas consumption for power generation by 96% and 50% respectively, slashing carbon emissions by an average of 65,000 t/y over the life of the agreement, according to Pacific Energy.

Pacific Energy Chief Executive, Jamie Cullen, said: “This is an excellent outcome for our long-time client, AngloGold Ashanti. We’ve been on the journey with them since 2012 and we are incredibly pleased to apply proven global technologies and our in-house expertise to help decarbonise their operations without losing power reliability or efficiency.

“To date, we are the only operator to successfully supply hydrocarbons-free power to mine sites in Australia.

“We expect our new system to reduce the mine site’s overall power generation emissions by 50%. It’s a really exciting prospect for us and AngloGold Ashanti, and one we’ve worked hard to achieve on our client’s behalf.”

Delivery of the project, which is slated to be Australia’s most remote large-scale hybrid power system, will be coordinated by Pacific Energy’s Remote Energy and Integrated Renewables divisions. The company will capitalise on its fully-integrated capabilities by manufacturing the BESS, high-voltage switch room and PV ring main units in house at its Western Australia-based facilities, it says.

Pacific Energy is expected to begin site works in July this year, with the project due for completion in early 2025.

Australia-based Perenti has provided an operational update and an upgrade to its financial year 2023 guidance to end-June 2023, which includes confirmation of a new contract for Barminco at Evolution Mining’s Ernest Henry mine in Queensland and a variation to expand its work scope at Regis Resources’ Garden Well mine in Western Australia.

The positive momentum noted in the operational update released on November 14 has continued as Perenti heads toward the end of the calendar year, with this momentum expected to continue into 2023, it noted.

“Since the release of the most recent operational update Perenti has secured improvements to commercial conditions across several Australian and African projects, including retrospective rate adjustments in relation to work that has previously been completed,” it said.

“These rate adjustments are the key catalyst in providing a further guidance upgrade one month after our previous upgrade.”

The contract at Ernest Henry (pictured) is for development work at the underground gold and copper mine. As Barminco transitions out of MMG’s Dugald River mine – where it has been carrying out development and production works – early next year, employees and capital resources from Dugald River will be mobilised to the new contract at Ernest Henry, it said. Underground development work at Dugald River, meanwhile, is to be taken on by Redpath Australia.

The Garden Well extension follows the commencement of underground mine development at the deposit in 2021.

On November 14, Perenti updated its FY23 guidance to forecast FY23 revenue of between $2.6-$2.7 billion ($1.7-1.8 billion). With the announcement of improved commercial conditions, and in consideration of securing work at Ernest Henry and scope growth at Garden Well, Perenti now forecasts that the company’s FY23 revenue will be between $2.7-$2.9 billion.

Mark Norwell, Managing Director and CEO of Perenti, said: “In addition to generating greater returns in FY23, we are focused on continuing to pursue business and project optimisation initiatives which will facilitate the delivering our 2025 strategy. Our strategy is designed to drive positive momentum in shareholder value well into the future. Perenti’s outlook is underpinned by our world-class Contract Mining Division, and the continued development of our Mining Services and idoba divisions. Our focus on generating enduring value for our people, clients and communities, will ensure we continue to deliver sustainable returns for our shareholders.”

MACA receives contract extension from Regis Resources at Duketon North

Mine operation news, Mining services, Precious metals, , , , , ,

MACA has announced the extension of its mining services contract with Regis Resources Ltd at the Duketon North Operations (DNO) in Western Australia, having provided mining services at the project since 2010.

The service offering includes a dedicated workforce of 258 personnel delivering drill & blast, load & haul, plant maintenance and technical services across the Regis open pits in the area.

This extension is expected to generate up to A$50 million ($36 million) per year in revenue for MACA and will utilise the contract miner’s existing fleet on site. DNO continues to run alongside the Duketon South Operations (DSO).

Both parties have signalled their intention to explore conversion of both the DSO and DNO contracts into an amalgamated partnership-style life of mine alliance arrangement post June 2023, MACA said. The asset produced 356,000 oz of gold in the 2021 financial year.

MACA’s work in hand position including this contract is in excess of A$2.6 billion at April 2022.

MACA CEO, Mike Sutton, said: “MACA is delighted to continue its long-standing relationship with Regis at the Duketon North Operation. Our team has a long-standing relationship with Regis and MACA is proud to be an ongoing part of this operation. This project will be undertaken utilising existing fleet and contributes to MACA’s secured mining work in hand in the Goldfields region, ensuring future work continues to consist of a balanced portfolio of commodities.”

Macmahon Holdings has bolstered its order book with a number of contract extensions involving the Tropicana and Telfer gold operations, in Western Australia, and the Hu’u copper-gold project, in Indonesia.

At the Tropicana mine, a joint venture between AngloGold Ashanti Australia Ltd (70% and operator) and Regis Resources Ltd (30%), Macmahon has been providing mining services since open-pit mining started in July 2012 under a life of mine alliance contract.

The additional work for Macmahon follows the completion of a detailed final cutback study of the Havana pit and subsequent confirmation of the optimal method to mine the deeper ore in the Havana ore body. Macmahon has now been provided with the scheduling detail for the cutback, which will add 155 Mt to the material to be mined from 2024.

The final cutback of Havana will extend the open-pit mine life by four years, from 2023 to 2027, and is expected to generate additional revenue of approximately A$470 million ($340 million), it said.

Macmahon has also extended its life of mine contract with Newcrest for the Telfer mine.

On August 12, Newcrest announced it will proceed with the West Dome Stage 5 cutback at Telfer. This new scope of work is expected to generate revenue of circa A$138 million and will extend Macmahon’s work on site to September 2024. This new work has been negotiated on updated rates, which are forecast to achieve the company’s internal financial hurdles, Macmahon explained.

In Indonesia, Macmahon has received a letter of award to construct an 11 km access road at the Hu’u copper gold exploration project on Sumbawa island. This work is valued at approximately A$18 million and is a further step in the company’s strategy to increase its revenue from mining support services.

Subject to finalisation of contract documentation, the project is forecast to commence in September 2021 and employ approximately 150 people. The Hu’u project is 80% controlled by Vale SA. Vale has previously said the project could produce more than 250,000 t of copper and more than 200,000 oz of gold.

Macmahon CEO and Managing Director, Michael Finnegan, said: “We are pleased to have secured this additional work which adds approximately A$600 million to our order book. A key highlight is the extension of our long-term alliance contract at Tropicana, which has been a cornerstone of our surface mining business in Western Australia for many years and has recently expanded into underground mining.”

Barminco, Ausdrill transport Rhino 100 raise borer to Regis’ Rosemont gold mine

Having become the first company globally to have taken delivery of a mobile raiseboring machine with uphole, downhole, and back reaming capability, Barminco is transporting a Rhino 100 Raise Borer to another client site in Australia.

With the help of its Perenti surface mining partner, Ausdrill, the newest addition was recently transported to Regis Resources’ Rosemont gold mine in Western Australia.

Just last year, Barminco sealed a three-year underground mining services contract with Regis at Rosemont, which has been transitioning from open-pit to underground mining at the operation.

Barminco said: “Through safe and rapid mobilisation, we are able to meet our clients’ needs and transport our equipment across multiple sites to complete a range of drilling campaigns.”

Since April 2019, Barminco’s first Rhino has travelled a combined 15,000 km between four client sites in the Goldfields of Western Australia, drilling a total of 3,843 m.

The Rhino is manufactured by TRB-Raise Borers in Finland but is equipped with Sandvik tools and is distributed by Sandvik. It is a fully mechanised and self-contained electro-hydraulic mobile raiseborer designed for slot raising in underground mining. The latest models also have an optional back reaming module.

In addition to helping transport Barminco’s latest Rhino to Regis’ site, Ausdrill has recently added a new Boart Longyear LF™160 drill rig and FREEDOM™ Loader combination to its diamond drilling fleet.

This rig reduces the crew’s “Hands On Steel” interaction, while improving overall safety standards, Ausdrill said.

When paired with the FL262 FREEDOM Loader, the LF160 combination is ideal for contractors who want to target sophisticated surface drilling exploration contracts that stipulate some of the highest safety standards, without compromising on productivity, Boart Longyear says.

Ausdrill’s Barminco to go underground at Regis Resources’ Rosemont gold project

Having recently closed a deal to acquire fellow contractor Barminco, Ausdrill has announced A$171 million ($123 million) in new work across the mining space.

Its Barminco business has sealed a three-year underground mining services contract with Regis Resources at the Rosemont project (worth A$113 million), in addition to receiving the nod to perform decline rehabilitation and development works at Western Areas’ new Odysseus mine. Meanwhile, Ausdrill has booked a 12-month contract from Consolidated Minerals for the provision of exploration drilling services at the Woodie Woodie manganese mine. This comes on top of a similar contract with Bellevue Gold at its namesake project in the Eastern Goldfields of Western Australia.

Ausdrill Managing Director, Mark Norwell, said: “These new projects demonstrate the diversity of the expanded Ausdrill group across different projects and resources, solid progress of Barminco, and the professional service our businesses have been providing to our customers.”

Rosemont has been a fully operational open-pit gold mine since March 2013 and is one of three Regis projects in the Duketon deposit area, 130 km north of Laverton in the Goldfields region of Western Australia.

Regis recently approved expansion of the mine to an underground operation located directly below the current Rosemont open pit, with Barminco to perform development and production work at the underground deposit. In August, the Regis board announced it had approved the development of an underground mining operation directly below the current Rosemont open pit exploiting the maiden underground mineral resource estimate of 1.4 Mt at 5.1 g/t for 230,000 oz of gold.

Barminco will commence mobilisation immediately and expects to employ around 100 staff at the project. Onsite works will commence in the March quarter, including commencing portal development at the southern end of the Rosemont Main open pit.

Barminco CEO, Paul Muller, said: “This project adds to Barminco’s extensive experience in the Western Australia Goldfields, with current mining projects at Sunrise Dam and Agnew. We will draw on our deep capability across Barminco’s people, equipment, systems, processes, and expertise in underground mining to ensure we provide a safe and reliable service at Rosemont and look to build a strong, long-term relationship with Regis.”

Meanwhile, the company has already mobilised on the 14-month contract to carry out decline rehabilitation and development works at Western Areas’ Odysseus mine. The contract builds on Barminco’s 14-years of continuous service for Western Areas at Forrestania, which includes the Spotted Quoll and Flying Fox mines where Barminco is the mining services provider.

Ausdrill’s work at the Woodie Woodie manganese mine, in the Pilbara of Western Australia, will commence next month, will run for 12 months and will require five RC drill rigs and one diamond drill rig to be drawn from the company’s existing fleet.

The company has already kicked off work at the Bellevue gold project, which will require around four diamond rigs to be drawn from the existing fleet.
