RUC Cementation Mining to carry out shaft work on Western Areas’ Cosmos nickel op

RUC Cementation Mining Contractors is set to carry out the shaft infrastructure design, construction and equipping for the Cosmos nickel operations in Western Australia after signing a contract with mine owner, Western Areas Ltd.

This contract represents the culmination of an engagement that has been ongoing for some six months, not including the excavation works which RUC is completing, having recently successfully holed the top leg of the shaft, RUC said.

“Furthermore, this cements a long-term relationship between both companies that spans over 15 years,” it added.

In Western Areas’ 2021 financial year (to June 30, 2021), capital investment at Cosmos totalled A$84 million ($63 million) for the year as the Odysseus mine construction activity increased, including full mobilisation of the underground mining contractor with over 3 km of underground decline and capital development being completed.

Odysseus mine development reached first ore earlier this month, with the raisebore back reaming having worked through 630 m of development at a diameter of 5.7 m, completing Leg 1 of the shaft hoisting and intake air system.

At the time, Western Areas Managing Director, Dan Lougher, said: “It is an exciting milestone to reach first ore and we now look forward to continuing ore production and construction activities, while also advancing offtake tenders for new nickel sulphide supply into the class 1 nickel market.

“The raisebore breakthrough (pictured) is also a key achievement that further de-risks project delivery and allows completion of the shaft sub-brace concrete works, as well as remaining surface civil works, associated with the shaft. Importantly, the work was completed without a safety incident, for which credit must be given to the site management team and RUC, the raise bore contractor.”

Barminco to take on Odysseus nickel mining gig for Western Areas

Perenti’s hard-rock underground miner Barminco has been awarded a development and production contract at Western Areas’ Odysseus mine, in Western Australia.

The contract at Odysseus, part of the Cosmos nickel operation, is valued at around A$200 million ($146 million) over five years and follows on from the earlier rehabilitation works completed by Barminco at the mine.

Western Areas acquired Cosmos in October 2015 and commenced the redevelopment of Odysseus in January 2019. Once in production, Odysseus is expected to produce 14,000-15,000 t/y of nickel concentrate, becoming Western Areas third nickel mine in Western Australia.

Western Areas Managing Director, Dan Lougher, said today (September 8) that excellent progress had been made on the underground and surface infrastructure works at Odysseus, with minimal COVID-19 impacts.

“We have reached a critical milestone with the firing of the full-face development of the Odysseus decline, which is now heading across to the orebody,” he said. “A significant amount of preparation and support work has been delivered across the site to reach this milestone.

“We now have our eye on the delivery of the first ore tonnes mined from underground in the first quarter of financial year 2022.”

Barminco’s Chief Executive Officer, Paul Muller, said the company was excited to continue its relationship with the Western Areas team, which began in 2005 at the Forrestania mine and has now grown to include the Cosmos nickel operation.

“Odysseus is a significant project to bring on-stream, and the five-year term demonstrates the trust and confidence Western Areas has in Barminco to continuously improve and deliver for them,” he said.

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.
