Perenti Limited says its Barminco business has been awarded a new development contract with Spartan Resources Ltd and extensions to four existing projects.

The scope of the Spartan Resources contract includes the construction of an underground exploration drill drive at the Dalgaranga gold project in the Murchison region of Western Australia. The drive has been designed to run in parallel and adjacent to the mineralised gold zones of Never Never, Pepper, Four Pillars and West Winds, to facilitate underground exploration and subsequently support future production plans.

Construction of the drive is due to start in the current quarter and is expected to take 10 months to complete. It will use a combination of existing capital equipment and an additional A$5 million ($3.3 million) of new growth capital.

The Dalgaranga project includes a fully-developed gold mining operation (currently on care and maintenance) and an extensive exploration landholding with outstanding opportunities for new discoveries, Spartan says. The open-pit mine was initially commissioned in 2018 and comprises a fully established gold mine, circa-2.5 Mt/y carbon-in-leach processing facility, modern camp accommodation and air strip. Dalgaranga produced 71,153 oz of gold for the 2022 financial year before being placed on care and maintenance in November 2022 to facilitate the implementation of a new strategic operating plan and a financial restructure. It was previously mined by NRW Holdings under an arrangement with mine owner Gascoyne Resources.

In February 2022, Spartan announced the details of a new 18-month exploration and strategic plan, underpinned by the Never Never gold deposit, targeting:

• A -plus-300,000 oz reserve at a grade exceeding 4 g/t at Never Never;
• A plus-600,000 oz resource at a grade exceeding 5 g/t at Never Never; and
• The development of a five-year mine plan aimed at delivering 130-150,000 oz/y.

In addition to the Dalgaranga project, Perenti says extensions to contracts have also been signed for the following project:

•  Siou and Wona underground at the Mana gold mine for Endeavour Mining plc in Burkina Faso;
• An existing copper and gold underground mining project in Canada;
• Spotted Quoll nickel mine for IGO Ltd in Australia;
• Mt Colin copper mine for Aeris Resources Ltd in Australia.

In combination, these projects are expected to contribute approximately A$160 million of revenue to FY25. The project extensions do not require new growth capital, Perenti says.

Mark Norwell, Managing Director & Chief Executive Officer of Perenti said “The greenfield underground at Dalgaranga project is an exciting opportunity. The resource has the potential to grow into a high-grade gold mine
and we look forward to supporting Spartan Resources to achieve their targets during the months ahead.

“In addition, the four contract extensions are another example of the 90%+-plus success rate the Contract Mining division has in extending and renewing contracts. Maintaining client relationships is critical to our long-term success, so we always strive to find ways to deliver value to our clients when possible.”

Gabrielle Iwanow, President of Contract Mining at Perenti, said: “We are pleased to be working with Spartan Resources on the new underground Dalgaranga gold project in Western Australia. Barminco has a long history of working with Western Australian gold producers and we look forward to building an excellent relationship with their team as they advance towards production.
