MACA Interquip Mintrex (MIQM) will be tasked with managing the definitive feasibility study (DFS) for Australia’s largest antimony deposit.
Larvotto Resources believes its Hillgrove gold-antimony project in New South Wales has the potential to produce approximately seven per cent of the world’s antimony, with first production targeted in late 2025 or early 2026.
As part of the DFS, which is set for completion in early 2025, Mintrex will oversee ongoing metallurgical testwork and design modification to optimise Hillgrove’s 500,000-tonne-per-annum process plant.
“The Larvotto team is looking forward to working with MIQM on the Hillgrove DFS, an important step in the development of the project,” Larvotto managing director Ron Heeks said.
“MIQM personnel have already been to site and are well underway in the task of providing the DFS that will allow Larvotto to commence project finance discussions and commence plant modification and mining at Hillgrove.
“Larvotto is currently targeting first production late 2025 early 2026 at which time it will supply approximately seven per cent of global antimony production* into a market that is heavily undersupplied.
“Larvotto will also produce a high-grade gold concentrate and gold bars. Both gold and antimony are trading at near record highs.”
Part of the Thiess Group, MIQM is an engineering and construction business that provides services to the mining and mineral processing sector. MACA Interquip acquired Mintrex in April, welcoming an esteemed engineering consulting, project and asset management business into the fold.
Larvotto has developed reagents and plant modifications set to further improve the efficiency of the Hillgrove plant, with the hope of delivering higher gold and antimony recoveries and further boost project economics.
Results from the testwork are expected in the near term.
