Larvotto Resources, Hillgrove restart timing now drives Larvotto’s value case

Can Larvotto’s Hillgrove antimony-gold restart into production by mid-2026 without permitting or execution slippage, because if it can, the company is sitting on what it says is Australia’s largest and most advanced antimony deposit with clear strategic value.

The latest updates have been constructive, with plant refurbishment tracking on schedule and budget, PYBAR already underground, and the project fully funded with $70.3m in cash plus a largely undrawn bond facility, but the stock still hinges on converting those milestones into a working mine rather than just a well-financed plan.

In our view, what matters is whether the company can turn its main growth asset into visible cash flow before near-term operating pressure overwhelms the story.

Larvotto’s valuation now turns on one thing: getting Hillgrove into production on time. The key update came in the December quarterly released on 30 January, when the company said plant refurbishment was on schedule and budget, PYBAR had started underground development, and first production remained targeted for mid-2026. That matters because a funded path to cash flow can shift a stock from exploration hope to operating reality.

The past year has been shaped by funding, construction, and strategic interest

Over the past 12 months, Larvotto has moved from concept risk toward execution risk, and that usually changes how the market prices a developer. The most important announcement in that period was the first bond drawdown in early December, which followed the broader project financing package and gave the company the money to fund construction, plant upgrades and mine development. In simple terms, Hillgrove stopped looking like a project searching for capital and started looking like a project being built.

That re-rating case was reinforced by a string of hard milestones. The EPCM contract for the plant upgrade was signed in October, PYBAR was appointed in November, underground development began in December, and January updates said the work remained on track. A rejected non-binding offer from US Antimony in October added another layer by signalling strategic value, particularly around antimony supply. Still, retail investors should separate strategic interest from cash generation.

This is a development story built around one asset and several payables

Larvotto is still a mineral developer, but economically the company is really about Hillgrove near Armidale. The project is being advanced toward production with a refurbished plant designed for about 0.525Mtpa throughput, and the planned revenue mix matters. Gold should provide a familiar and liquid source of revenue, while antimony is the strategic metal that gives the asset a different valuation angle. Tungsten may become a useful third payable product if metallurgical work continues to support a saleable concentrate.

That mix matters because it can improve project resilience compared with a single-commodity mine. Gold can support cash flow when specialty metal markets are uneven, while antimony can boost margins if prices remain firm and supply stays tight. The near-mine satellite areas also matter to the business model because Larvotto is not relying on one isolated ore source. Metz, Freehold, Clarks Gully and Eleanora-Garibaldi all sit within trucking distance of existing processing infrastructure, which means exploration success has a clearer commercial pathway than it would at a greenfield project.

The market will likely stay practical until one catalyst changes the debate

The balanced view is straightforward. On the upside, Larvotto controls a rare mix of antimony and gold in an asset that is close to production, funded for restart, and still showing resource growth around the mine. Government focus on antimony, the previous approach from US Antimony, and the possibility of tungsten by-product revenue all support the case that Hillgrove may be worth more than a standard small gold restart. Those factors can matter a lot if operations begin smoothly.

On the downside, developers usually get little credit for future cash flow until they demonstrate it. Final permits still need to land, commissioning has to work, underground development must keep pace with the schedule, and commodity prices remain outside management’s control. For now, the stock is likely to be judged on milestones rather than broad narratives.
