The aim of this work targeting high-grade sulphide gold mineralisation at depth is to confirm survey effectiveness as proof of concept ahead of potential larger-scale geophysical surveying across the wider project area.
GAP Geophysics Australia, under the supervision of Russell Mortimer from Southern Geoscience, will conduct Induced Polarisation (IP) and Electromagnetic (EM) trial surveys at the Bruno-Lewis and Helens deposits.
Kin’s exploration program has significantly advanced the geological model for the Cardinia region.
Three mineralising styles have been identified – low sulphidation epithermal, volcanogenic hosted massive sulphide (VHMS) and orogenic structurally controlled lode style.
Physical property testing of mineralised core from Bruno-Lewis and Helens deposits has indicated that IP and EM surveys are capable of identifying the various styles of sulphide-rich, high-grade gold mineralisation.
Ground-based surveys using these techniques will be applied at Bruno-Lewis and Helens to determine the most effective method in an in-situ environment.
Location of trial lines for IP and EM loop. The Lewis line crosses to the south of the Lewis trial pit and the Helens line crosses over the sulphide-rich portion of the Helens resource.
Results expected next month
This work will be undertaken in late October, with transect lines over high-grade sulphide mineralisation, and results and interpretation are expected to be completed by mid-November.
Subject to a successful outcome of the trial, Kin intends to apply ground-based geophysical surveying over a wider area within the region to assist with targeting for upcoming drill programs.
Around 60% of the CGP is covered by recently transported cover and, as a result, has been subject to minimal exploration.
The Cardinia area which will be the target area for the trial contains a resource of 372,000 ounces, the majority of which lies beneath old workings in areas of shallow oxide and outcropping mineralisation.
This forms part of the overall project resource of 841,000 ounces defined in both supergene and deeper primary mineralisation with considerable potential to grow this with further drilling.
