Drilling extends mineralised zones at depth and along strike
New lodes identified close to existing workings
Results provide broader insight for future project planning
Larvotto Resources Ltd (ASX:LRV) continues to advance work at the Hillgrove Antimony-Gold Project, with new drilling expanding mineralised extensions and revealing fresh geological insight that may reshape development planning.
Larvotto Resources Ltd (ASX:LRV) has shared another round of encouraging exploration results from the Clarks Gully prospect at the Hillgrove Antimony-Gold Project in New South Wales, drawing attention across the landscape of ASX mining stocks. The program continues to build a clearer geological picture, with mineralised structures now traced deeper and farther along strike, while fresh lodes appear to be emerging near the main system.
This progress arrives at a time when interest in diversified minerals across the ASX stock market is broadening, and discussions around project evolution are becoming increasingly strategic across the ASX100, ASX200, and ASX300 groups, as well as among investors who monitor ASX dividend stocks for stable resource-linked exposure.
Extending mineralisation beyond earlier expectations
The latest diamond drilling at Clarks Gully confirms that mineralisation is not confined to previously mapped zones. Instead, the system continues along strike toward the northern trend and deepens below earlier planning shells.
Core samples reveal dense stibnite veins and strong visual indicators of gold-bearing material, reinforcing the geological theme that has defined Hillgrove for generations. Each new hole adds context, suggesting continuity rather than isolated pockets.
Equally important, the drilling supports the broader geophysical model guiding exploration. Resistivity anomalies highlighted earlier are now showing clear relationships with mineralised shoots, strengthening confidence in the exploration strategy and improving the accuracy of future targeting.
Discoveries inside and beyond the main lode
While much of the work focused on extensions of the primary Clarks Gully lode, drilling also intersected fresh structures in the immediate footwall. These zones appear parallel to the main mineralised corridor and may represent new shoots with meaningful continuity.
Such discoveries matter because they can reshape mine-design thinking. A cluster of closely spaced lodes may enable more efficient underground development, shorter access drives, and enhanced flexibility when scheduling extraction areas over time.
The team also intercepted broader halos of tungsten mineralisation surrounding the gold-antimony structures. Although this mineralisation sits outside the core lode, it contributes another layer of value. Tungsten associations help map the broader system, acting both as a geological marker and as a possible future by-product stream.
Reinforcing geological continuity at depth
Another key outcome from the program is deeper insight into the nature of mineralisation beneath earlier design envelopes. Current drill intercepts demonstrate that the system persists well below the levels previously prioritised for surface extraction planning.
By intersecting mineralisation beneath the planned open-pit footprint, the program confirms that continuity extends into zones historically considered less accessible. This validates earlier interpretations that Hillgrove’s endowment is vertically extensive, unfolding through stacked structures and lenses that remain open at depth.
Such findings create optionality. Instead of focusing exclusively on shallower areas, development pathways may naturally evolve toward a more underground-weighted approach, supported by more selective mining techniques and reduced surface disturbance.
New thinking around mine design and development
A central part of the evolving strategy at Hillgrove involves the transition toward dry-stacked tailings. This shift not only modernises environmental management but also alters the physical footprint of the project.
With tailings infrastructure now envisioned differently from early studies, the open-pit concept is likely to be reassessed. Underground access may gain priority, enabling the project to chase high-grade corridors while maintaining tighter dilution control and greater scheduling precision.
The updated drilling supports this transition. By expanding high-grade continuity both down plunge and along strike, the program feeds directly into new resource evaluations that align with these design choices. The result is a more resilient development framework that adapts to new geological knowledge rather than forcing the orebody to fit older models.
Northern strike remains open for further exploration
The northern extension intersected in recent drilling remains open. This openness invites further exploration along the structural corridor, where resistivity data continues to hint at additional targets.
As the program steps progressively outward, the geological picture becomes richer. Vein orientations, alteration styles, and structural fabrics are now being mapped with greater clarity, supporting increasingly detailed models that inform every subsequent drill collar.
The message is simple: the system has not been closed off. Instead, each round of drilling broadens the canvas.
Tungsten adds depth to the project narrative
Alongside gold and antimony, tungsten continues to surface as an important satellite mineral. Found on the fringes of the main lodes, scheelite zones offer insight into the evolution of the hydrothermal system that formed Hillgrove.
Beyond geological interest, tungsten may play a part in long-term planning. As supply chains diversify globally, strategic minerals like tungsten attract growing attention. Even peripheral mineralisation can influence future scheduling decisions, processing flowsheets, and economic assessments.
At Clarks Gully, tungsten effectively layers another dimension onto the project, creating scope for multi-metal extraction strategies that align with modern resource planning philosophies.
Implications for the broader Hillgrove resource
The new data sits largely outside earlier mine shells that were shaped by past assumptions and legacy infrastructure plans. With these constraints easing, Hillgrove can now be viewed through a refreshed lens.
Resource updates are expected to integrate deeper continuity, new parallel structures, and broader halos of mineralisation found during the latest phase of drilling. Each incremental dataset feeds into refined block models, strengthening the foundation for upcoming development studies.
Importantly, the narrative is shifting from isolated intercepts to system-scale understanding. Clarks Gully is now clearly part of a broader, evolving mineralised corridor with room to grow along multiple directions.
Next steps — expanding knowledge through continued drilling
Larvotto plans to extend exploration across the broader Hillgrove footprint, targeting untested resistivity features and stepping along strike toward structural trends that remain open. Further drilling will also probe deeper areas beneath the current infrastructure footprint.
These programs aim to connect known zones, define new lodes, and collect the geotechnical and metallurgical data required for future design refinements. With each campaign, the geological story becomes more coherent, guiding development in a disciplined and informed manner.
Hillgrove continues to evolve as an integrated polymetallic system, where antimony, gold, and tungsten interact across multiple structural domains, supporting a long-term view built on geological confidence rather than speculation.
Why Clarks Gully matters in the bigger picture
Clarks Gully is more than a single deposit. It serves as a proving ground for exploration tools, a test case for future underground concepts, and a window into the deeper structural engine that powers the Hillgrove field.
By validating geophysical targeting methods, expanding mineralised envelopes, and unveiling fresh lodes, the program demonstrates that disciplined exploration remains central to resource growth across Australia’s historic mining districts.
As market interest in diversified metals persists, projects with strong geological continuity and adaptive development pathways remain firmly positioned within the broader conversation around sustainable mineral supply.
