Larvotto Resources Hits 62.6g/t AuEq as Clarks Gully Stacked Lodes Grow
Key Takeaways
- Ten new diamond drill holes (CLG128–CLG137) all intersected targeted mineralisation at Clarks Gully, with the headline intercept of 9.5m @ 8.07g/t AuEq from 345.5m in CLG128 including a 0.5m @ 62.6g/t AuEq high-grade shoot.
- All new results sit outside the existing May 2025 Mineral Resource Estimate of 647kt @ 1.6% Sb and 2.1g/t Au for 6.7g/t AuEq, directly pointing to an upcoming resource upgrade.
- Drilling has confirmed a stacked, parallel lode system with CLG129 returning multiple separate intersections from 255.9m to 375m depth, and the high-grade ore shoot remains open down plunge.
- Tungsten is emerging as a genuine third commodity, with grades including 1m @ 7.27% WO₃ in CLG129 and 1m @ 5.44% WO₃ in CLG136, supported by prior metallurgical testwork demonstrating approximately 90% tungsten recovery.
- Six additional holes (CLG138–CLG143) are pending assay, with LIBS scanning and geological logging described as encouraging, and an updated Mineral Resource Estimate plus Mineral Reserve publication targeted as part of the underground mining application process.
Multiple high-grade zones confirmed as Clarks Gully grows in scale
Diamond drilling at the Clarks Gully deposit has returned standout gold-antimony-tungsten results from ten new holes, with Larvotto Resources (ASX: LRV) reporting a headline intercept of 9.5m @ 8.07g/t AuEq from 345.5m in CLG128, including 0.5m @ 62.6g/t AuEq. All ten holes (CLG128 to CLG137) intersected targeted mineralisation within the 100%-owned Hillgrove Antimony-Gold Project in New South Wales, confirming the system extends at depth and to the south of the current resource.
The new results sit outside the existing Mineral Resource Estimate (MRE) of 647kt @ 1.6% Sb and 2.1g/t Au for 6.7g/t AuEq (published May 2025), pointing to meaningful resource growth potential. Importantly, the system is proving to be a true three-commodity story, with gold, antimony, and tungsten all contributing to the emerging picture at Clarks Gully.

Drilling results at a glance
The table below summarises the key intercepts from the first ten holes of the current 16-hole program.
| Hole ID | From (m) | Interval (m) | AuEq Grade (g/t) | Notable Feature |
|---|---|---|---|---|
| CLG128 | 345.5 | 9.5 | 8.07 | Includes 0.5m @ 62.6g/t AuEq |
| CLG129 | 339.7 | 14.3 | 2.96 | Includes 1m @ 23.69g/t AuEq |
| CLG129 | 375.0 | 1.0 | 60.4 | Separate high-grade shoot intercept |
| CLG131 | 262.0 | 12.5 | 4.92 | — |
| CLG133 | 327.5 | 1.5 | 29.0 | — |
| CLG136 | 290.0 | 9.0 | 7.05 | Includes 1m @ 45.09g/t AuEq |
Assays remain pending for CLG138 to CLG143, the final six holes of the program. LIBS (Laser Induced Breakdown Spectroscopy) scanning and geological logging of those holes are described as encouraging, supporting Larvotto’s view that further results will contribute positively to the resource base.
A stacked lode system — what the geology is telling investors
Most gold and antimony deposits are built around a single mineralised vein or lode. Clarks Gully appears to be something more substantial. The drilling is confirming a stacked, parallel lode system, meaning multiple distinct mineralised structures running alongside one another rather than a single isolated zone.
What this means in practice:
- Each parallel lode adds independent mineralised width and grade to the system
- The total mineralised corridor is wider and more continuous than a single-vein model would suggest
- Resource estimates built on single-lode assumptions can grow materially when additional parallel structures are confirmed
CLG129 is the clearest example of this at Clarks Gully. That hole returned multiple separate intersections at different depths within the same drill hole, from 255.9m all the way to 375m, confirming stacked lodes sitting beneath the existing resource model rather than a single continuous structure.
The announcement also confirms a plunging ore shoot — a high-grade core of mineralisation that follows a defined trajectory through the rock. Critically, it remains open down plunge, meaning the richest part of the system has not yet been closed off by drilling. For investors, open-ended systems with stacked lodes have historically supported significant resource upgrades when followed up with additional drilling.
Tungsten emerges as a material third commodity
Tungsten is shaping up as a distinct and growing value driver at Clarks Gully, separate from the established gold-antimony story. The standout intercept from CLG128 was 6.1m @ 1.43% WO₃ from 345.5m, but the grades get sharper in other holes: CLG136 returned 1m @ 5.44% WO₃ from 298m and CLG129 returned 1m @ 7.27% WO₃ from 375m.
Tungsten mineralisation is not isolated to one or two holes. Significant WO₃ assays were returned across CLG128, CLG129, CLG130, CLG133, CLG135, and CLG136, demonstrating that tungsten is widespread within the Clarks Gully system. The announcement notes that prior metallurgical testwork (ASX announcement, 19 November 2025) has demonstrated tungsten recoveries of approximately 90% with significant feed grade upgrading, supporting the potential to produce a saleable tungsten concentrate. This is testwork context only and does not represent confirmed production economics.

Managing Director Ron Heeks captured the broader significance of the parallel lode structures and the tungsten endowment:
Ron Heeks, Managing Director
“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. The extension of broad zones, high-grade tungsten zones and continued gold-antimony mineralisation provides a strong foundation for further resource growth and future drilling.”
What comes next — from drilling to development
Larvotto has laid out a clear, near-term development pathway for Clarks Gully:
- Assays pending for CLG138 to CLG143 (the remaining six holes from the 16-hole program)
- Geological interpretation and resource modelling are underway to incorporate the new results and define follow-up targets
- An updated Clarks Gully Mineral Resource Estimate to be published incorporating all new data
- A Mineral Reserve publication is targeted as part of the proposed underground mining application
- Engineering, metallurgical, and permitting workstreams are described as “well advanced”
- Regulatory approvals have been received to drill Curry’s Block, the historical gold-antimony-tungsten workings, as Larvotto reviews the broader tungsten endowment across the Hillgrove mineral field
Tenure risk is not a factor here. Clarks Gully sits entirely within granted Mining Lease 1332. The broader Hillgrove context matters too: production has recently commenced at Hillgrove, described in the announcement as Australia’s largest antimony mine, with multiple drill rigs active simultaneously across the mineral field. Clarks Gully is positioned as the next development target within an already operating project, potentially adding a second near-term production source to the portfolio.
