Larvotto Resources has engaged MACA-Interquip-Mintrex (MIQM) for the upgrade and refurbishment of its 100 per cent owned processing plant at the Hillgrove antimony-gold project in New South Wales.
The engineering, procurement, and construction management (EPCM) contract, which also covers design, looks to upgrade the Hillgrove plant to roughly 0.525 million tonnes per annum in throughput, including an ultra-fine grinding circuit and a filtered (dry) tailings circuit.
Larvotto managing director Ron Heeks said that while early works are underway, “executing the EPCM contract with MIQM locks in scope, governance and a firm schedule to deliver a safe re-start on time and budget”.
“The work on the secondary crushing and tailings filtrations is progressing well, with the MIQM team onsite and building to around 60 people over the next few months,” he said.
“We also commend the team for repairing the main transformer, restoring grid power and delivering a more reliable, lower-cost power supply to site.”
The company said it was poised to become a major antimony producer, set to produce seven per cent of global antimony requirement, with commissioning to commence in Q3 of 2026.
“As governments prioritise to secure stable supply chains and stockpiles, Larvotto’s head-start and near-term production provide a real timing advantage and de-risk execution,” Heeks said.
“At the same time, our ongoing exploration provides significant upside potential to build resources and mine life, ensuring Hillgrove is a long-term supplier of critical materials.”
