Situated in Western Australia’s Fraser Range region, the Big Bang tenement is in a district quickly getting a name for itself as one with established potential for magmatic nickel copper sulphide mineralisation.

The highly prospective Central Fraser Zone is home to IGO’s (ASX:IGO) Nova Bollinger nickel-copper-cobalt deposit, Legend Mining’s (ASX:LEG) Mawson discovery 50km to the north and Galileo Mining’s (ASX:GLM) adjacent Lantern Project.

Carawine Resources (ASX:CWX) three conductors were identified following a high-temperature SQUID (HTS) moving loop electromagnetic (MLEM) survey over three priority targets areas named BB1, BB2 and BB4 which were originally spotted from aeromagnetic and geochemical anomalies.

Each of these target areas were interpreted to represent potential mafic-ultramafic intrusive complexes prospective for the formation of magmatic nickel-copper sulphides.

Upcoming diamond drilling

Now, CWX managing director David Boyd says the company is looking forward to drill testing these conductors and extending the geophysical survey coverage across other target areas at Big Bang.

Diamond drill testing of these conductors – located within or on the edge of magnetic anomaly complexes, is planned for the first half of 2023 along with further moving loop electromagnetic surveys.

Three drill holes have been planned as an initial test of each of the BB1 A, BB1 B and BB2 A conductors.

Meet the conductors

Conductor BB1 is a strong and discrete bedrock anomaly in the northwest of the BB1 survey grid, identified across two main survey lines – Carawine considers it as a high priority target for drill testing.

Despite its low conductance levels, the spatial association of BB1 B with a subtle linear magnetic high and a >30ppm Ni soil anomaly makes it a significant target that also warrants drill testing – the same goes for Conductor BB2 A.

Conductor BB2 A exhibits an exponential late time decay curve with a time constant of ~30msec, potentially indicating a sulphidic or stratigraphic source to the anomaly.
