Larvotto Resources Limited has commenced first gold and antimony production at the Hillgrove Mine in New South Wales.

Following the completion of an extensive redevelopment and plant upgrade program, full production began on 31 August 2026 after staged process plant commissioning started in July 2026. Under an EPCM contract executed with Interquip Construction Pty Ltd in October 2025, the processing plant was refurbished and upgraded to a throughput capacity of approximately 0.525 Mtpa.

Hillgrove is forecast to produce 4,900 tonnes of antimony and 40,500 ounces of gold per annum over an initial eight-year mine life. The operation is expected to supply approximately 7% of global antimony demand and over 50% of supply from sources outside of China, establishing Larvotto as Australia's largest antimony producer.

“It is an outstanding achievement by the Company and a milestone day for our critical minerals industry in Australia, with Hillgrove now in production. In less than three years, we have taken Hillgrove from acquisition, resource and reserve assessment, PFS, DFS, funding and construction to production, establishing Larvotto as Australia's largest antimony producer and a globally significant new source of this essential critical mineral.” 

— Ron Heeks, Managing Director

Larvotto plans to commence tungsten concentrate production at the project in the near term to further broaden its critical minerals output.
