Kiarra Prospect Shows Strong Resistivity Anomalies Linked to Historic Gold-Antimony

Survey Reveals New Exploration Opportunities

Larvotto Resources Limited (ASX – LRV) has announced encouraging results from a recent Gradient-Array Induced Polarisation (IP) and Resistivity survey conducted at the Kiarra Prospect, part of its wholly owned Hillgrove Antimony-Gold Project in New South Wales. The survey, carried out by Fender Geophysics, has identified strong resistivity anomalies that align closely with historic surface workings known for antimony and gold mineralisation.

These resistivity highs are interpreted as potential extensions of mineralised lodes, offering fresh targets for exploration in an area that, despite its historic surface mining, has never undergone drilling. The Kiarra Prospect lies just over 4 kilometres north-northeast of the Hillgrove mine site and is situated near other promising prospects such as Clarks Gully.

Structural Parallels with Established Mining Zones

One of the most intriguing aspects of the survey results is the structural resemblance between Kiarra and the nearby Metz Mining Centre, where Larvotto is preparing to commence mining. Both areas exhibit northwest-trending shear corridors hosting multi-phase antimony-gold-tungsten mineralisation. The IP survey detected linear resistivity features at Kiarra that mirror the orientation and style of mineralised lodes at Metz, suggesting a shared geological framework that could bode well for resource expansion.

Historic drilling at the adjacent Kiarra West Prospect has returned significant near-surface intercepts, including assays up to 17.82 grams per tonne gold equivalent over one metre, reinforcing the prospectivity of the area. These results underscore the potential for discovering economically viable mineralisation through targeted drilling.

Strategic Next Steps and Broader Exploration Plans

Larvotto’s Managing Director, Ron Heeks, highlighted the importance of these findings in expanding the company’s exploration footprint beyond the immediate mine area. The company plans to follow up with step-out drilling to test the newly defined IP anomalies at Kiarra, aiming to confirm the presence and extent of mineralisation. Additionally, Larvotto intends to expand its geophysical program across other priority targets within the Hillgrove Project, including further IP surveys to develop three-dimensional models of mineralisation depth and continuity.

The company’s methodical approach, combining modern geophysical techniques with historical data and field mapping, exemplifies a cost-effective strategy to unlock new resources. Given the refractory nature of gold associated with antimony at Hillgrove, these efforts could prove pivotal in delineating zones amenable to modern extraction methods.

Context Within Larvotto’s Portfolio

Hillgrove remains a cornerstone asset for Larvotto, complementing its other projects such as the Mt Isa copper-gold-cobalt project in Queensland and the Eyre multi-metals project in Western Australia. The company’s ongoing exploration success at Hillgrove, particularly with the application of induced polarisation surveys, reinforces its potential to grow resources in a historically challenging but strategically important mineral field.

While the IP survey results at Kiarra are promising, the true test will come with drilling outcomes that can validate these geophysical targets. Investors and industry watchers will be keenly awaiting updates as Larvotto advances its exploration program.
