Cyprium Metals Limited (ASX:CYM) has received a boost for its upcoming Mineral Resource Estimate release with some promising final diamond drillhole results from the Phase 1 programme completed at Nanadie Well in Western Australia earlier this year.
The company’s 5-hole (1,328m) diamond drilling programme was designed to test for sulphide mineralisation below a depth of 50m associated with a layered mafic intrusive unit outlined in the previous reverse circulation (RC) drilling programmes.
Extensive zones of copper sulphide mineralisation were intersected in all holes from the diamond drilling programme to a drill hole depth of 312m.
The oxide and sulphide mineralisation currently extends over a strike length of 750m and remains open along strike to the north and south and across strike to the west.
The results from the all the drilling completed to date at Nanadie Well will be used in the preparation of a Mineral Resource estimate for inclusion in the Murchison Copper-Gold Project scoping study.
Detailed evaluation of the drill core and multi-element data is ongoing to better understand the geological controls to the primary copper mineralisation. Encouragingly, elevated nickel and palladium values were found associated with several of the significant copper intervals.
“This is another set of fantastic drill results from this extensive copper deposit emerging at Nanadie Well, which remains open in multiple directions,” Managing Director, Barry Cahill, said.
“We will soon be commencing a mineral resource estimate in advance of metallurgical studies to optimise the extraction of copper and gold from a potential heap leach operation. In the meantime, work is progressing to refine our understanding the geological controls of the primary copper mineralisation, which assists in the planning of the next phase of drilling.
“In addition, a preliminary evaluation of the multi-element geochemical data is showing an encouraging association between copper, nickel and palladium.”
