Vortex has been around for more than 14 years and specialises in induced polarisation and electromagnetic geophysical methods.

It counts among its achievements conducting the high powered downhole electromagnetics on hole SPD021 that led to the discovery of Monty near Degrussa in WA and the high-powered EM survey that defined the EM conductor at the Vulcan prospect near Doolgunna, also in WA.

For Hammer, Vortex will undertake a pole-dipole double-offset array induced polarisation survey over the Bronzewing South mineralised corridor.

It has started the permitting process and plans to start the IP survey once clearance has been received.

The IP survey has been designed to detect sulphide zones below cover rocks to refine drill hole targeting.

The sulphide zones are considered significant because gold mineralisation at the Bronzewing mine has been associated with sulphides.

Hammer Metals chairman Russell Davis said the engagement of Vortex heralded the beginning of Hammer's 2019 field program at Bronzewing South.
