Capital, a leading mining services company, has announced the award of a material drilling contract in Nevada with Nevada Gold Mines and associated rig purchases, together with an update on the ramp up of operations at its Ivindo iron ore contract in Gabon.

The three-year drilling services contract with Nevada Gold Mines (NGM) in the US spans a wide range of drilling services including diamond, both surface and underground, and underground reverse circulation. Drilling spans a number of operations across NGM including underground diamond drilling in the Leeville underground mine within the Carlin complex, underground RC drilling in Carlin and diamond drilling at the Robertson project within the Cortez complex.

NGM is a joint venture between Barrick (61.5% ownership) and Newmont (38.5% ownership), with Barrick as operator. NGM operates three Tier One gold assets: Carlin, Cortez and Turquoise Ridge, consisting of 10 underground mines, 12 open-pit mines and associated facilities.

The contract will consist of nine rigs and will include equipment with advancements in automation for improved safety and efficiency, Capital said.

The contract is expected to generate annualised run rate revenues of circa-$35 million once all the rigs are fully operational from 2025, at margins commensurate with the broader group, Capital said. The company will purchase new rigs with associated equipment for the contract with capital expenditure expected to be circa-$20 million, predominantly falling in 2024.

In Gabon, the company reported that ramp up of operations at its load & haul, crushing and drilling contract with Ivindo Iron SA, majority-owned by Fortescue, was proceeding well.

“We have now commenced drilling operations to assist in further defining this world-class deposit,” Capital said. “The majority of the mining equipment is now in country with operations also already underway, and crushing due to commence later in the year.”

Peter Stokes, Chief Executive Officer of Capital, said: “This new drilling contract award represents a landmark moment for Capital as we extend our geographic reach in drilling into North America, adding to our existing and growing operations in Canada with MSALABS. It is a strong endorsement of our long-standing commitment to world leading standards in both safety and productivity.

“We are pleased to further expand our services with Barrick, having begun our relationship across operations in Africa before extending more globally, first at the Reko Diq mine in Pakistan, earlier this year, and now to the Nevada Gold mines complex in the United States.

“It is also great to see a continuation of our decisive and strategic move to reposition and improve our contract portfolio, set out in the second half of 2022, focusing on large-scale mine sites and Tier-1 projects with significant growth potential. The addition of world-class contracts in 2023 across Reko Diq, Ivindo and now Nevada presents significant further opportunity and a strong platform as we look into 2024.”

Barrick trialling autonomous and battery-electric tech at North America mines

Barrick Gold’s automation and electrification efforts look to be gaining pace, with the leading gold miner revealing it has been testing out new technology at some of its operations in the US and Canada.

In its recently released annual report, Barrick said the first stage of a project designed to retrofit an autonomous system at its Carlin gold mine, in Nevada, had been completed successfully.

Matthew Majors, Open Pit Operations Superintendent at Carlin Surface, said in a presentation last month that multiple underground evaluation deployments, surface drilling OEM evaluation, and non-OEM surface production haulage options had been evaluated across the Barrick and Newmont jointly-owned Nevada Gold Mines business.

While the company didn’t provide any more details on the project, Barrick has previously leveraged ASI Mining’s OEM-agnostic autonomous solution at its jointly-owned South Arturo gold operation, also in Nevada. This saw the completion of a proof of concept (POC) using five haulage units “that have delivered over 5.5 Mt faster than any other similar POC in the industry”, Barrick said last year.

At Kibali, in the Democratic Republic of the Congo, which remains a world leader in underground automation with multiple autonomous machines operating on the same haulage level, the company recently completed a trial to use this technology on the mine’s production levels. This means a single operator can now control up to three machines acting semi-autonomously in different zones, Barrick said.

It added: “An additional system, which will provide real-time visibility of the underground operations, including personnel and equipment tracking, is currently being commissioned.”

And, lastly, on the electric vehicle front, the company said its Hemlo gold mine, in Ontario, Canada, has introduced a battery-powered development drill “as a first step towards establishing the potential of this new technology”.

Hemlo recently moved from a combined open-pit and underground owner-operated mine to an underground-only contract mining model as part of a plan to transition Hemlo into a Tier Two asset with a life of mine well into the future.

Barrick’s Turquoise Ridge gold operation is also evaluating new battery-electric technology, with the company confirming a battery-powered underground haul truck is being trialled at the mine.
