Larvotto ships first 68 tonnes of antimony concentrate from Hillgrove to Wogen Resources

Larvotto Resources has shipped its first truckload of antimony concentrate from the Hillgrove Mine in New South Wales to offtake partner Wogen Resources, a move the company says converts the site into a revenue-generating operation.

The shipment totalled 68 tonnes, and Kalkine Media reports the delivery at the mine gate on 14 October 2026 fulfilled a delivery condition that triggers an initial part-payment under Larvotto’s offtake agreement; Larvotto has said a second, final payment will follow independent assay confirmation of the metal content.

Larvotto’s managing director, Ron Heeks, described the delivery as a milestone as Hillgrove becomes a supplier of critical minerals and said the antimony processing circuit is operating at a steady rate.

Company statements and coverage from multiple outlets report that plant availability is ahead of schedule, daily processing tonnages are rising and concentrate grades are improving, which Larvotto presents as evidence the operation is scaling toward steady production.

The operation is designed to produce roughly 4,900 tonnes of antimony and 40,500 ounces of gold per year; Larvotto has said those rates would make Hillgrove one of the world’s larger antimony producers and give it about 7 per cent of global antimony supply at planned production levels, a figure cited explicitly in The Sydney Morning Herald.

The company also reports ongoing metallurgical testwork on tungsten mineralisation, and it is narrowing preferred processing equipment and flowsheets as it targets the start of tungsten processing in 2027.

The immediate commercial consequence recorded in the coverage is the triggering of an initial payment under the offtake contract, with the final tranche held pending independent assay results that will confirm concentrate metal content.

Outlets reproduce Larvotto’s statement that, with the antimony circuit steady, management will broaden operational focus to optimise gold concentrate and gold doré production, signalling a near-term shift in production priorities within the plant.

Reporting notes the Hillgrove redevelopment and plant upgrade program preceded the shipment and underpins the company’s claim that the site has moved from commissioning to revenue generation. Coverage does not provide independent verification of the company’s production forecasts, assay results, or the timetable for gold doré or tungsten processing beyond Larvotto’s statements.

The Sydney Morning Herald includes the company claim that Hillgrove will control about 7 per cent of global antimony supply at planned rates; other outlets repeat the planned annual antimony and gold figures but do not independently confirm the market-share calculation.

Kalkine Media and other reports emphasise the contractual mechanics—mine-gate delivery triggering part-payment—while Larvotto and mining-focused outlets emphasise operational performance metrics.

For stakeholders, the shipment represents the first monetised output from Larvotto’s redevelopment of Hillgrove and a test of the company’s ability to meet contractual quality specifications through independent assay.
