ASX-listed Larvotto Resources has signed an engineering, procurement and construction management (EPCM) contract with MACA-Interquip-Mintrex (MIQM) for the upgrade and refurbishment of the processing plant at its 100%-owned Hillgrove antimony/gold project in New South Wales.

The contract scope covers design, EPCM and the refurbishment or upgrade the plant, including an ultra-fine grinding circuit and a filtered (dry) tailings circuit, to about a 525 000 t/y throughput.

Early works are already under way on secondary crushing and tailings filtration areas.

Larvotto says it is set to become the next major antimony producer, slated to produce 7% of global antimony demand, with commissioning to start in the third quarter of 2026.

“While early works to upgrade the Hillgrove processing plant are under way, executing the EPCM contract with MIQM locks in scope, governance and a firm schedule to deliver a safe restart on time and budget.

“The work on the secondary crushing and tailings filtration is progressing well, with the MIQM team on site and building to around 60 people over the next few months. We also commend the team for repairing the main transformer, restoring grid power and delivering a more reliable, lower-cost power supply to site,” says Larvotto MD Ron Heeks.

“With a clear pathway and funding in place to complete the plant upgrade and move into production, Hillgrove is set to become the next major Western producer of strategic antimony, supported by gold revenue in record-price environments for both.

“As governments prioritise to secure stable supply chains and stockpiles, Larvotto’s headstart and near-term production provide a real timing advantage and de-risks execution. 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 minerals,” he adds.
