Cooper Metals Ltd (ASX:CPM) has completed a round of diamond drill holes at the Mt Isa East Copper-Gold Project in northwest Queensland, encountering visual mineralisation in all four holes at the King Solomon prospect.
Of particular note were semi-massive sulphides observed in the 23MEDH002 drill hole, which CPM says has confirmed the presence of a "strongly mineralised breccia zone in the central plunging copper-gold shoot".
A second drill hole, 23MEDH004, also intersected mineralisation of about 10 metres in width, consisting mostly of sulphide veins in quartz carbonate-rich rock from about 111 metres of depth.
Samples submitted, assays incoming
“Diamond drilling at King Solomon 1 is now complete with visual sulphides intersected in all four holes," Cooper Metals managing director Ian Warland said.
"As well as 23MEDH002, which intersected a strongly mineralised zone of around 11 metres downhole with semi-massive sulphides in brecciated rocks, hole 23MEDH004 intersected around 10 metres down hole of strongly mineralised sulphide veins in quartz carbonate-rich rock.
"Samples for assay have now been submitted to the laboratory with results expected in October.
"A trial downhole electromagnetic survey is underway to test the mineralisation’s geophysical response and its applicability to deeper drill targeting.
"Geological logging and interpretation continues and we look forward to updating the market on the drill hole assays and geophysical results as they come to hand.”
Cooper is trialling a down-hole electromagnetic (DHEM) survey of all four diamond-drilled holes at present, designed to test if the copper-gold mineralisation has sufficient electromagnetic response that could be used to target sulphide mineralisation at depth.
The company expects the modelled results to be ready in late September.
