Argent’s rock chip sampling has confirmed areas of extensive copper prospectivity at its Copperhead project within Western Australia’s Gascoyne province.

High-grade copper assays were returned from the Anomaly A copper-zinc prospect (12.43% copper and 0.38% zinc), the Illirie Creek prospect (6.21% to 20.44% copper), the Anomaly A and lllirie Creek Copper prospects, and Anomalies C (a) and C (b). Highly encouraging silver results are closely associated with Anomalies C (a) and C (b) Copper Prospects.

All copper mineralisation is hosted within the Discovery Formation Siltstone with Argent Minerals (ASX:ARD) noting that numerous untested synclinal structures represent excellent walk-up targets.

“We are encouraged to have further ground confirmation of the high-grade copper mineralisation over 5 additional copper prospects within the Copperhead project,” managing director Pedro Kastellorizos said.

“These mineralised areas have shown to be extensive in terms of the strike length within the regional synclinal structures and Discovery Formation Siltstone. These structures extend over 74km of strike, have excellent potential to host mineralisation and remain completely untested to date.

“We are confident in further delineation of surface copper mineralisation based on our understanding of the structural/lithological controls which host the copper and zinc mineralisation within our project areas.”

Copperhead Project

Copperhead is located about 350km east-northeast of Carnarvon with access provided by the sealed North West Coastal Highway and then via along Maroonah Road with gravelled station tracks throughout the tenements.

First pass exploration was carried out over the Anomaly A, Prospect 3A, Anomaly C (a), Anomaly C (b) and Illirie Creek Copper prospect areas in November 2022 with the company also assessing the logistics of its upcoming extensive ground-based exploration program.

Illirie Creek is centred on three large costeans which were excavated by BHP in 1971-73.

Copper mineralisation is located within the Discovery Formation Siltstone which outcrops over 30km from the Mt Palgrave prospect to Illirie Creek.

The costeans have been excavated from northeast to southwest over 50m and at 100m spacing with a 1973 BHP report recording a 13.4m section of the northernmost costean as containing 0.77% copper while a >10m section of the central costean recorded more than 1% copper.
