Cyprium Metals Limited (ASX:CYM) has identified extensive near-surface oxide and sulphide mineralisation in its Phase 1 diamond drilling programme at the Nanadie Well Copper-Gold Project in Western Australia.
The second diamond drill hole NWD2001 has shown the continuation of the extensive shallow intersection immediately below oxide copper-gold halo.
Highlight of hole NWD2001, which is located ~320 metres to the north of NWD2004, includes an interception of 144m @0.7% Cu & 1.5g/t Au from 25.0m.
The mineralisation remains open along strike to the north and south and across strike to the west. It does not outcrop and is covered by one to 25 metres of transported material. Preliminary investigations of the Nanadie Well deposit data indicates potential for oxide and sulphide mineralisation over the currently identified strike of 750m.
The company’s 1,328 metre Nanadie Well diamond drilling programme was completed in January 2021 and was primarily designed to test the sulphide mineralisation below 50m depth at the deposit. There is an extensive shallow sulphide copper-gold intersection continuing immediately below the oxide material derived from the layered mafic intrusive unit that has been outlined in the previous Reverse Circulation (RC) drilling announcements and quarterly reports.
Drillhole NWD2001 also includes a crackle breccia zone with high grade silver sulphide mineralisation which had not been previously encountered at the project and requires further analysis.
Executive Director, Barry Cahill, said the results from this drilling, the Phase 1 RC January 2021 campaign and subsequent drill programmes will be used in the preparation of a JORC 2012 compliant mineral resource estimate for Nanadie Well during 2021 for inclusion in the Murchison Copper-Gold scoping study.
We are pleased to announce the second set of assay results from the Phase 1 Nanadie Well diamond drilling campaign that had all diamond drill holes intersecting visible copper mineralisation,” Mr Cahill said.
“Diamond drill hole NWD2001 was commenced from outside of the supergene mineralised corridor and angled west at 60 degrees towards the sulphide zone. The resulting assays returned a consistent 232 metre copper mineralised intersection from 109 metres downhole.
“The drillhole also intersected a crackle breccia zone with high grade silver sulphide mineralisation from 303 metres downhole, which requires further work to define the mineralisation style.
“Downhole geophysics was conducted from the diamond drill hole to assist in the planning of the Phase 2 drilling campaigns.
“These are another set of fantastic drill results for this extensive deposit, which is very shallow, broad, consistently mineralised and is open in multiple directions.”
