Gold and base metals explorer Carawine Resources Limited (ASX:CWX) has commenced a new geophysical survey programme exploring for magmatic nickel-copper sulphide deposits at the company’s Big Bang tenement, located in the Fraser Range region of Western Australia.
The MLEM survey has been designed to test for conductive bedrock anomalies at three priority targets named BB1, BB2 and BB4. These targets were identified from geophysical and geochemical data, with each interpreted to represent potential mafic-ultramafic intrusive complexes prospective for the formation of magmatic nickel-copper sulphides.
“The commencement of MLEM surveying at Big Bang represents the first on-ground nickel exploration program on our 100%-owned Fraser Range tenements and continues a very active period of exploration for the company,” Managing Director, David Boyd, said.
“We’ve been drilling continuously at our nearby Tropicana North Gold Project since last July, and with our recent successes at Hercules and Big Freeze, more assay results to come, and more drilling planned, we have a full program lined up for the coming months
“We look forward to updating the market with the progress of these programmes and results as they become available.”
Fraser Range Project – Big Bang
The Big Bang tenement is located in the Central Fraser Range region, within and on the margins of the Fraser Range Metamorphics magnetic-gravity complex (FRM). The FRM is considered highly prospective for magmatic nickel-copper (Ni-Cu) mineralisation, hosting IGO’s Nova-Bollinger nickel-copper-cobalt deposit and several Ni-Cu prospects including Legend Mining’s Mawson discovery 50km to the north, and Galileo Mining’s Lantern project which adjoins Big Bang.
Eight targets within the Big Bang tenement, considered prospective for magmatic Ni-Cu mineralisation, have been identified to date based on a combination of regional and detailed geological, magnetic and geochemical data (BB1 to BB7, BB9). One gold target (BB8) has also been identified from auger soil geochemistry, immediately south of the BB1 target.
MLEM Survey Areas
The first phase of exploration at Big Bang will comprise moving-loop transient electromagnetic (“MLEM”) surveys over the three selected priority targets BB1, BB2 and BB4
• BB1 is a distinct magnetic low within the FRM wrapped by magnetic high “limbs” with coincident anomalous nickel (>30ppm) and copper (>20ppm) geochemical results in auger soil samples.
• BB2 is a magnetic low with a >30ppm Ni auger anomaly coincident with its south-eastern edge and a >20ppm Cu auger anomaly centred on the magnetic low.
• BB4 comprises a large, distinct magnetic low within the FRM.
Each target area will be surveyed using a 200m x 200m square wire loop moved along survey lines with a SQUID B-field sensor run in “slingram” mode offset 150m from the loop edge. This is designed to detect any conductors that may be related to semi-massive or massive nickel-copper sulphides to more than 300m below surface.
The MLEM survey programme will comprise approximately 845 stations and is expected to take about 40 days to complete. Results will be available soon after completion of the programme.
