GreenTech (ASX:GRE) strike top-end copper at Yannery

GreenTech Metals have returned a broad range of significant copper strikes from the Yannery prospect, revealing a mineralised zone up to 100 metres wide, plunging for at least 150 metres, and a new potential source of enormous copper tonnage to add to its Whundo resource in the Western Australian Pilbara.

A headlining strike of 21 metres @ 2.1 per cent copper tops the best return from last week’s results at the Austin prospect – which sent the GRE share price soaring by over 164 per cent by the close of trading.

GreenTech Executive Director Thomas Reddicliffe said it was another exciting prospect that could add significant tonnage to Whundo.

“These results from Yannery have not only identified significant copper mineralisation but also confirmed the presence of high-grade copper lodes, some of which were targeted by the historic underground mining undertaken some 50 to 100 years ago,” Mr Reddicliffe said.

“Going forward we will be focussed on defining the extent of the deposit as it has not yet been systematically tested. We have also been encouraged by the DHEM survey results which shows a conductor extending down dip beyond the extent of the drilling.”

“This deposit has been largely overlooked in the past, but it is now proving to be an attractive prospect due to it being at surface, with copper-dominant mineralisation and carrying gold and silver credits.”

A result of 1m @ 23.1% Cu and 37.1g/t Ag struck the high-grade lode, and there are records of periods at Yannery where historic mining averaged a ridiculous 21 per cent copper.

Drilling also tapped a new mineralised zone at depth, appearing separate from historic near-surface workings and suggesting that Yannery could stand as a multi-layered deposit.

GreenTech plans to further explore the untested area at Yannery both laterally and downdip as it continues circling its next upgrade to Whundo’s red metal resource.
