Cooper Metals Ltd (ASX:CPM) has begun to build on a successful maiden drilling program with assays from 11 more holes – from a total of 27 reverse circulation (RC) holes – confirming strong copper-gold mineralisation at King Solomon prospect of the Mt Isa East Project in Queensland.
Drilling results have extended the known mineral system to the north, south and down-dip, with the remaining assays expected to confirm continuity of mineralisation.
The company has interpreted the broad zones of copper results from this latest batch of assays to support a large iron oxide copper-gold (IOCG) system, with magnetite and pyrite alteration associated with the higher-grade core centred around the host shear zone.
“Outstanding copper-gold intercepts”
Assay results from the higher-grade core at King Solomon include:
- 19 metres at 1.6% copper and 0.21 g/t gold from 123 metres, including 5 metres at 4.5% copper and 0.57 g/t gold;
- 7 metres at 1.5% copper and 0.16 g/t gold from 123 metres including 4 metres at 2.2% copper and 0.26 g/t gold;
- 14 metres at 1.0% copper and 0.09 g/t gold from 76 metres including 4 metres at 2.1% copper and 0.23 g/t gold;
- 5 metres at 1.1% copper and 0.15 g/t gold from 112 metres;
- 10 metres at 1.0% copper and 0.04 g/t gold from 50 metres including 3 metres at 2.1% copper and 0.08 g/t gold;
- 3 metres at 1.2% copper and 0.1 g/t gold from 91m including 1-metre at 2.7% copper and 0.21 g/t gold;
- 2 metres at 1.6% copper and 0.05 g/t gold from 86 metres; and
- 1-metre at 1.3% copper from 107 metres.
“Mineralisation has been intersected to over 100 metres deep and is open at depth. The IP is proving to be an invaluable guide to IOCG style of mineralisation found at King Solomon.
“With just under half the drill holes assayed to date and the laboratory processing the rest of the samples as a priority, we expect to update the market shortly.”
Cooper Metals intends to follow up the pending assays with further exploration, to be planned and executed once results are received.
