Larvotto Resources (ASX:LRV) has extended mineralisation below and south of the current resource at the Clarks Gully deposit within its Hillgrove Antimony-Gold Project in New South Wales.
Assays from 10 of 16 diamond drill holes identified gold-antimony-tungsten mineralisation across multiple stacked structures.
Hole CLG128 returned 9.5m @ 8.07 grams per tonne gold equivalent (AuEq) from 345.5m, including 0.5m @ 62.6g/t AuEq and 0.8m @ 42.7g/t AuEq.
CLG129 intersected 14.3m @ 2.96g/t AuEq from 339.7m, including 1m @ 23.69g/t AuEq. A separate interval returned 1m @ 60.4g/t AuEq from 375m.
Other results include 12.5m @ 4.92g/t AuEq from 262m in CLG131 and 9m @ 7.05g/t AuEq from 290m in CLG136, including 1m @ 45.09g/t AuEq.
Tungsten mineralisation was encountered in several holes. CLG128 returned 6.1m @ 1.43% tungsten trioxide (WO3) from 345.5m, while the 1m interval in CLG129 from 375m graded 7.27% WO3. CLG136 also returned 1m @ 5.44% WO3 from 298m.
Larvotto interprets Clarks Gully as a stacked lode system containing several parallel mineralised structures and ore shoots plunging south. The system remains open along strike and at depth.
Managing Director Ron Heeks says the parallel structures indicate mineralisation extends beyond the main lode.
“Importantly, we are seeing strong results from multiple mineralised structures that are parallel to the main lode, which reinforces our view that Clarks Gully hosts a broader mineralised system with considerable exploration upside,” Heeks says.
Resource update and development plans
Clarks Gully currently hosts 647,000 tonnes @ 1.6% antimony and 2.1g/t gold, equivalent to 6.7g/t AuEq.
Larvotto will incorporate the new drilling into geological modelling and an updated mineral resource estimate. Meanwhile, assays remain pending for holes CLG138–CLG143.
The deposit lies within granted Mining Lease 1332, where engineering and metallurgical studies are underway. Larvotto plans to prepare an ore reserve estimate to support a proposed application for underground mining.
The company says it is also assessing tungsten across the wider Hillgrove mineral field and has received regulatory approval to drill the historical gold-antimony-tungsten workings at Curry’s Block.
Larvotto began gold and antimony production at Hillgrove earlier this month. The operation is forecast to produce 4,900 tonnes of antimony and 40,500 ounces of gold annually over an initial eight-year mine life.
Multiple drill rigs remain active across the mineral field, targeting resource expansion, conversion, and new discoveries.
Larvotto Resources operates the Hillgrove Antimony-Gold Project and also holds the Mt Isa Copper-Gold-Cobalt Project in Queensland and the Eyre Multi-metals and Lithium Project near Norseman in Western Australia.
