Cooper Metals Ltd (ASX:CPM) has completed reverse circulation (RC) drilling on four regional copper-gold prospects — Raven, Mafic Sweats North, Mafic Sweats South and Yarraman — at the Mt Isa East Project in Western Australia.
A total of 12 RC drill holes were completed for around 1,800 metres of drilling, with 523 one-metre samples sent to the laboratory in Mt Isa. The bulk of the samples are from the Mafic Sweats South Prospect.
This recent round of drilling was following up a significant thickness of copper oxide mineralisation including 65 metres at 0.34% copper from surface, intersected at Mafic Sweats South last year. The follow-up drilling was testing deeper and along strike from the 2023 drill holes.
The drilling was also designed to test for extensions to copper-gold mineralisation intersected in 2023 at Raven and a coincident induced polarisation survey (IP) chargeability anomaly and a copper soil geochemistry anomaly at the Yarraman copper-gold prospect.
Cooper Metals managing director Ian Warland said: “RC drilling was completed on all four prospects, completing 12 RC holes for around 1,800 metres in total.
"Over 500 one-metre samples have been selected for laboratory assay based on the presence of anomalous copper in pXRF and visual logging by a company geologist. I’m pleased with the progress of the drilling and look forward to updating the market with the assay results once the data has been received and analysed.”
Cooper Metals will now interpret the assays and plan follow-up exploration activities, while investigations continue into the prospectivity of the Brumby Ridge prospect.
