Larvotto Resources (ASX:LRV) is planning to drill test geophysical and historical results at the Kiarra prospect, within the Hillgrove Antimony-Gold Project in New South Wales, after completing a survey.
With an expanding geophysical program at Hillgrove, the mineral explorer intends to drill test newly defined induced polarisation (IP) anomalies to test for potential new zones of antimony-gold mineralisation.
Following completion of a gradient-array IP and resistivity survey, the company noted a strong correlation between resistivity highs and the most significant of the historical workings located at the northern end of Kiarra.
Resistivity highs and linear features may be indicative of mineralised lodes as most are associated with surface workings. The higher resistivity is interpreted as an indication of increased silicification, which is seen to coincide with known mineralisation throughout the Hillgrove Mineral Field.
Managing Director Ron Heeks says the prospect survey highlights further priority step-up drill targets, showing the potential of geophysics to target unknown and under-explored mineralisation at Hillgrove.
“The correlation between the resistivity highs at Kiarra, along with the locations of mapped historical surface workings at Kiarra are exciting as it clearly aligns with the structures seen at the Metz area that contains the majority of the current Larvotto resources and is where mining will commence shortly,” Heeks says.
“Whilst Kiarra has several historical workings, it has never been drill tested.”
At Hillgrove, there are several historical mining areas that identified gold mineralisation, but the presence of antimony made extraction nearly impossible at the time.
“For that reason Kiarra appears to be yet another area that holds great potential for both gold and antimony,” Heeks adds.
The Hillgrove Project, covering 254km2, is expected to begin producing antimony and gold in 2026, subject to a final investment decision.
Larvotto anticipates Hillgrove to produce 7% of global antimony requirements when global supply is tightening and Western governments are prioritising strategic supply chains.
