GreenTech fires up the drill rigs at bonanza historic copper prospect

GreenTech Metals has begun drilling at a long forgotten copper gem in the Pilbara which once delivered ore at bonanza grades of over 20%.

Drilling has started at Yannery, located to the north-east of the Whundo copper mine, where GreenTech (ASX:GRE) boasts an existing resource of 2.7Mt at 1.14% copper and 1.14% zinc.

It is one of two significant orebodies along a 2km strike at the Whundo project, with the Ayshia resource containing 0.92Mt at 1.3% copper and 2.3% zinc to the north-east.

Yannary is 800m from Whundo and 700m from Ayshia, providing massive exploration upside within the overall Whundo mineral field – and it is not just a pure greenfields target.

Between 1920-1958 intermittent production records demonstrate Yannery produced 1132t of copper ore at a remarkable average grade of 21%.

Between 1951-1968 a further 1911.8t of cupreous ore was extracted from the oxidised and supergene zone averaging 12.87% copper.

Evidence of working remains on surface with underground working comprising an adit and shafts to shallow depths present at the project, limited to a near surface oxidised portion of the prospect.

Despite the impressive historical statistics, Yannery has not been followed up since Fox Resources drilled nine RC holes in 2006, delineating mineralised zones in the prospect outside of the historically mine area, alongside fixed loop and downhole EM surveys.

“GreenTech expects the program at the Yannery prospect will provide a better understanding of the geometry and thickness of the mineralised horizon and potentially extend known mineralisation,” GreenTech told investors on the ASX today.

“As part of this program, a further hole will be drilled at Austin which will target the highly conductive plate identified from the DHEM survey completed on hole 22GTRC033 which was drilled last year.”
