A first pass rock chip reconnaissance survey has identified and confirmed extensive outcropping copper mineralisation within the Mt Palgrave prospect at Argent Mineral’s Copperhead project in WA.  

High-grade copper assays include 2.42%, 4.14%, 5.92%, 8.8%, 14.96% and 21.1% copper with strongly anomalous zinc mineralisation up to 0.11% from 12 rock chip samples.

Compare that to historical rock chip sampling and costeaning copper assays from exploration work in 1966-1967 of 1.12%, 4.6%, 6.8% and 14.2% copper.

The potential structural stratiform copper-zinc mineralisation is hosted within the discovery formation and Argent Minerals (ASX:ARD) estimates it to be over 84km in length within the project areas.

Extensive copper mineralisation

The company says the mineralisation is more extensive than the historical exploration suggests.

“Field based observations have confirmed strong copper assay results, as the copper mineralisation is vastly more extensive than previously reported from the exploration work completed from 1966-1967,” MD and CEO Pedro Kastellorizos said.

“We are confident there are further outcropping copper mineralisation extensions on the western, eastern and the synclinal hinge zones as all these areas remain untested.”

“The extensive strike length of these untested areas just over the Mt Palgrave area varies from 2.5km to 3.3km with visible copper mineralisation,” Kastellorizos says.

Additionally, visible copper mineralisation in the form of malachite is yet to be assayed.
