The WRC Nickel-Copper Sulphide Project provides significant discovery potential.
Magnetic images indicate several embayments along the lower contact zones of the intrusive complex. These embayments may act as sites for ponding of Ni-Cu sulphide minerals. The embayments are indicated in the image below which has been rotated with north to the bottom of the page to align with the generalised model.
In addition, a low amplitude magnetic anomaly extending from the keel region of the intrusion (K1) suggests that the ultramafic feeder zone to the WRC dips to the north, below the granite. A significant number of Ni-Cu sulphide orebodies occur near the lowermost keel of a lopolith where mixing and crystal fractionation are enhanced as shown in the generalised model and this area represents potential Ni-Cu sulphide mineralisation.

A Geological Total Electromagnetic Field (GEOTEM) airborne electromagnetic survey has been carried out over the entire WRC. Numerous GEOTEM anomalies have been identified including several anomalies in the keel region. These anomalies may represent sulphides and coincide with elevated Ni in geochemical sampling.
GEOTEM conductivity and preliminary EM targets
A ground-based moving loop electromagnetic (EM) survey has been undertaken across the K1 anomaly and an EM plate model that fits the observed ground EM survey data has been produced to aid in drill targeting of the conductive source.
Podium plans to drill test the priority geochemical and geophysical anomalies for Ni-Cu sulphide mineralisation. The drilling will be complimented with downhole geophysics to test for off-hole conductors.
