Larvotto unearths new drill targets at flagship NSW gold project
Larvotto says its gradient-array induced polarisation (IP) and resistivity survey hit the mark, lighting up zones that were historically rich in antimony and gold. The results back the company's geological model and give a clear green light for it to chase new, low-cost mineral discoveries across the project.
Fender Geophysics ran the IP survey, which picked up strong chargeability and resistivity signals exactly where Larvotto had already found mineralisation, stacking the odds in Larvotto's favour of finding further lookalikes. The best new targets sit right under the old Clarks Gully pit and extend to the north, setting the stage for some exciting follow-up drilling.
The IP technique, which measures how the ground resists and stores electrical charge, is especially suited to Hillgrove, where mineralisation is tightly linked to sulphide-rich and silica-altered rocks. Both rock types appear to stand out like a sore thumb in the IP data.
'The IP survey demonstrates the opportunity to use it as a cost-effective exploration tool across the broader Hillgrove Project area.'
Larvotto Resources managing director Ron Heeks
Larvotto Resources managing director Ron Heeks said: 'The IP survey has delivered an important validation of our geological model at Clarks Gully with strong correlation between our known mineralisation and the high chargeability and resistivity responses. It not only confirms the continuity of the NW-SE trending system and associated splays but also demonstrates the opportunity to use IP as a cost-effective exploration tool across the broader Hillgrove Project area.'
Larvotto now plans to fast-track a second phase of geophysics, this time deploying dipole-dipole arrays to build a 3D model of the mineralised system and test the depth extent of the anomalies. This data will feed directly into the company's next drilling program to zero in on new zones of antimony-gold mineralisation at Clarks Gully.
It will also give the company scope to widen its line of sight on fresh targets across the wider Hillgrove project.
At the same time, the company is gearing up for more geophysical surveys to sterilise the grounds under its planned mine infrastructure area. This will allow Larvotto to weave exploration into future development planning and reduce the risk of flicking the switch to production.

Larvotto locks in $60 million to fire up Hillgrove gold play
Larvotto Resources has nailed down a pivotal $60 million equity raise to restart its Hillgrove antimony-gold mine in New South Wales, positioning the company to tap into soaring demand for critical minerals by mid-2026. The cash injection was secured via a two-tranche placement to Australian and international investors priced at 68 cents a share - a modest 6.2 per cent discount to Larvotto's last traded price. The offer was swamped with demand, with the board now launching a $5 million share purchase plan at the same price for existing shareholders. The placement comes hot on the heels of Larvotto's US$105 million (A$159.6 million) senior secured bond issue, completed just days earlier, meaning the Hillgrove project is now fully funded through to production with a 70:30 debt-to-equity split. According to the company, that structure comfortably surpasses its expectations and reflects the project's high-margin, fast-payback nature. 'With the financing stage for Hillgrove addressed, our sole attention turns to construction and commissioning of this unique brownfield opportunity.' Larvotto Resources managing director Ron Heeks The $60 million will be used to fund pre-production capital expenditure, early site works and operational readiness teams at Hillgrove, alongside ongoing exploration to expand the resource base. With all boxes ticked on the financing front, Larvotto's full attention now turns to construction and commissioning. Larvotto Resources managing director Ron Heeks said: 'The Hillgrove project is the only new source of western antimony supply expected to come online in the next four years. Now, with the financing stage for Hillgrove addressed, our sole attention turns to construction and commissioning of this unique brownfield opportunity. To be operating such a high IRR project within Australia and to be within 12 months of first production at a time of particularly strong interest in new critical mineral sources is very exciting.'

Larvotto plumps finances with US$105M for NSW gold/antimony mine
Larvotto Resources has raised US$105 million to help restart its Hillgrove gold and antimony project in New South Wales, thanks to a fully subscribed senior secured bond issue backed by major Australian and overseas investors. Larvotto says the issue highlights the compelling development case for Hillgrove and its potentially pivotal role in supplying critical antimony to global markets. Investors in the bond issue include leading natural resources and renewable energy companies. The company will invest the new proceeds, its existing cash and other equity to restart its Hillgrove project. Larvotto expects to settle the issue on August 1 and to start drawing on the funds in October. In June, Larvotto received NSW Department of Planning, Housing and Infrastructure approval for its Modification 6 application to upgrade processing infrastructure and underground mining access at the historic mine. 'For the company to be in a position to undertake a bond issue is a strong endorsement of the project and its projected returns.' Larvotto Resources managing director Ron Heeks The critical regulatory milestone enables the company to restart mining and processing activities, has bolstered the company's confidence in final-stage financing and paves the way for first production in 2026. Funds will be allocated to critical development activities, including the transition to dry-stacked tailings, subject to departmental approval. Larvotto has opted for dry-stacked tailings at Hillgrove due to its environmental, engineering and cost advantages and because it is particularly suited to the site's steep terrain and existing infrastructure. Larvotto Resources managing director Ron Heeks said: 'The bond completion marks another milestone for Larvotto Resources and its Hillgrove project. Completed well within the expected project finance timeline, for the company to be in a position to undertake a bond issue is a strong endorsement of the project and its projected returns.'
