Special Report: Anova has started the 2022 field exploration program at its newly expanded Big Springs gold project in Nevada with induced polarisation and resistivity surveying now underway.

The IP survey across key target areas is aimed at characterising the response over known mineralisation and to identify targets for ongoing exploration.

Anova Metals (ASX:AWV) noted that disseminated sulphides are chargeable and generally respond well to IP surveying, which measures contrasts in resistivity and chargeability.

This is particularly true in Carlin-style gold mineralisation where disseminated sulphides are associated with gold mineralisation – a boon for the company given that this is exactly the type of mineralisation it is chasing at Big Springs.

It expects areas of known sulphide mineralisation to respond well to IP surveying; and additional anomalous responses at depth and under marine cover to provide excellent follow-up targets.

IP surveying

The IP survey consists of three east-west lines totalling 6km.

Line 6 has good control in terms of drilling and gold grades, cutting through known mineralisation. This line is also designed to explore possible depth extensions of high-grade mineralisation at North Sammy and South Sammy.

Meanwhile, Line 2 will investigate the response at Beadles Creek and Crusher zone; as well as explore for sulphide mineralisation under marine cover east and west of the Beadles Creek fault while Line 10 will look for depth extent to the shallow oxide gold mineralization at Mac Ridge and South Sammy SW.

The IP survey will take about three weeks to complete with inversion modelling of final data and integration with results from existing drilling and geology undertaken to guide follow-up work such as drilling and expanded IP surveys.
