Larvotto Resources has extended high-grade antimony-gold-tungsten mineralisation at Clarks Gully about 100 metres beyond its 2025 resource model, with drilling also identifying several hanging-wall lodes. The results could support a larger resource and a potential underground feed source for Hillgrove, but assays, modelling and permitting work remain outstanding.
- CLG140 intersected 32.0m at 5.68g/t AuEq, including 8.0m at 13.77g/t
- CLG141 intersected 29.1m at 6.06g/t AuEq, including 8.7m at 14.83g/t
- High-grade tungsten intersections reached 11.13% and 9.47% WO3
- Multiple hanging-wall lodes were identified beyond the existing resource footprint
- Assays from CLG142 and CLG143 will feed an updated resource estimate
Clarks Gully Extends Beyond Existing Resource
Larvotto Resources Limited (ASX:LRV) has drilled into a deeper and wider version of the Clarks Gully orebody, with hole CLG141 extending the mineralised footprint approximately 100 metres down plunge and along strike beyond the 2025 resource model.
The strongest main-lode results came from CLG140, which returned 32.0 metres at 5.68g/t gold equivalent from 260 metres, including 8.0 metres at 13.77g/t AuEq. CLG141 delivered 29.1 metres at 6.06g/t AuEq from 339.4 metres, including 8.7 metres at 14.83g/t. Both holes intersected the interpreted ore shoot outside the current model, while mineralisation remains open at depth.
Tungsten Adds High-Grade Intercepts
CLG141 also produced a string of hanging-wall intersections above the main structure, including 4.4 metres at 12.81g/t AuEq, 6.0 metres at 11.97g/t, 2.0 metres at 14.26g/t and 1.0 metre at 14.81g/t. The results support Larvotto’s interpretation of a stacked, multi-lode system rather than a single mineralised zone.
Tungsten was particularly striking in the hole. Intersections included 0.4 metres at 11.13% WO3 from 161.8 metres and 0.8 metres at 9.47% WO3 from 219.8 metres, alongside a 1.0-metre interval grading 3.38% WO3. Larvotto says the tungsten-bearing veins could provide an additional source of value beside the established gold and antimony mineralisation, although the reported AuEq figures depend on stated commodity prices and recovery assumptions and do not establish that every metal will be recovered or sold.
Resource Update Comes Before Development Decision
The latest results come from a 16-hole diamond drilling programme targeting continuity below and along strike of Clarks Gully’s existing 647-kiloton resource, which grades 1.6% antimony and 2.1g/t gold. Assays for the final two holes, CLG142 and CLG143, are still pending. Geological modelling will incorporate all 16 holes before Larvotto produces an updated Mineral Resource Estimate.
The company is also preparing engineering and metallurgical studies for a potential low-footprint underground operation at Clarks Gully, within Mining Lease 1332, as a secondary feed source for the Hillgrove plant. That ambition sits alongside Hillgrove’s move into production, including the company’s first gold and antimony concentrate milestone earlier this month, but the proposed Clarks development remains subject to permitting, further drilling, metallurgical work, a maiden Mineral Reserve and economic assessment.
Pending Assays Will Test the Expansion Case
Follow-up drilling is planned to test the open extensions at depth and along strike, improve continuity in the resource model and target the newly identified hanging-wall lodes. Larvotto is also reviewing tungsten potential elsewhere across the Hillgrove field, including at Curry’s Block, where approval has been obtained to drill historical gold-antimony-tungsten workings.
The immediate test is less geological than administrative: whether the remaining assays and updated modelling convert an encouraging exploration envelope into a materially larger resource with a credible mining pathway. Until that work is complete, Clarks Gully is a promising extension to Hillgrove’s production story, not yet a defined second source of ore.
Bottom Line?
The drilling strengthens the case for resource growth at Clarks Gully, but the next valuation step depends on the pending assays, updated MRE and evidence that underground development can be permitted and economically justified.
Questions in the middle?
- Will CLG142 and CLG143 confirm the continuity suggested by CLG140 and CLG141?
- How much of the newly identified hanging-wall and tungsten mineralisation will enter the updated resource estimate?
- Can Larvotto secure the approvals, engineering outcomes and mining economics needed to make Clarks Gully a secondary Hillgrove feed source?
