Larvotto Resources Ltd (ASX:LRV) has published an initial resource for the tungsten found at its Hillgrove gold and antimony project in New South Wales, with this being estimated at 4,774 tonnes of tungsten trioxide (WO3) – or 8,766 kilotonnes at 0.05% WO3.

Within the overall number, the majority (2,606t) is in the inferred category, while another 2,168t is measured and indicated.
This is the first time that tungsten – which has historically been mined alongside gold and antimony – has been given its own resource estimation at Hillgrove, although tungsten was included as part of a recent definitive feasibility study (DFS) over the project as a whole.
Lavotto has identified tungsten in 2 main areas: the first being Brackins Spur, which has a mineral resource of 2,111kt at 4.3 g/t Au (gold), 0.9% Sb (antimony) and 0.16% WO3 and contains high yield tungsten zones of 40kt @ 1.6% WO3 (627t WO3).
The second is Clarks Gully, where the mineral resource is 350kt @ 2.2 g/t Au (gold), 1.8% Sb (antimony) and 0.06% WO3 contains high yield tungsten zones of 125kt @ 0.17% WO3 (213t WO3).
Managing director Ron Heeks said the tungsten resource estimate represented an important milestone for Larvotto.
“While Hillgrove has been historically known for its wealth of high-grade antimony and gold mineralisation, there is an exciting tungsten opportunity that exists at the project,” he said.
“Recent drilling at Clarks Gully has delineated tungsten-rich mineralisation, and analysis of historic data has identified significant under explored tungsten potential throughout the Hillgrove mineral field, as demonstrated by the resource also identified at the Metz area.
“Although we have always known of the tungsten potential at Hillgrove, we focused on gold and antimony for the DFS. Now that the DFS is complete, we will assess other opportunities to add further value at Hillgrove, including tailings retreatment for gold, antimony and
tungsten as well as tungsten as a mining by-product.”
Larvotto shares have risen since the news, and at 10:40 AEST, they were trading at 68.5 cents – a rise of 4.58% since the market opened.
