Critical minerals player Greentech Metals Ltd (ASX:GRE) has confirmed continuity of copper mineralisation in two mineralised shoots which it believes point to significant expansion capacity at the Whundo copper-zinc project in Western Australia.
Greentech has rolled out a 1,710 metre long reverse circulation drilling program at Whundo, with a specific focus on the shoot, Austin and Ayshia, and recent work has indicated that copper grades of up to 4.6% are evident at the play.
At Austin, intercepts included 16 metres at 1.2% copper (Cu), 0.12% zinc (Zn), 0.035 grams per tonne (g/t) gold (Au) from 230 metres, including 8m at 1.5% Cu, 0.21% Zn, 0.039g/t Au from 230m – all from one hole.
Meanwhile, a hole at Ayshia pulled up results including 10m at 1.2% Cu, 1.2% Zn, 0.09g/t Au from 260m, including 3m at 3.1% Cu, 2.6% Zn, 0.23g/t Au from 261m.
The company has also carried out DHEM (Down-hole EM) surveys which show definitively that the Cu-Zn shoots continue down-dip at Austin and Ayshia beyond 230m depth.
Executive Director, Tom Reddicliffe said the drilling and surveying work was helping to boost plans for resource growth at Whundo.
“We’re thrilled with the stage one drill results, which show real potential to significantly grow Whundo’s current 6.2Mt copper-zinc resource by targeting down-dip extensions to our known shoots,” he said.
“Based on our exploration results to date we firmly believe that we can continue to expand the Whundo copper resource to potentially underpin a copper project.
“Furthermore, with Whundo situated on a granted mining lease and with processing options potentially being available either through our Alliance with ANAX or Artemis Resources’ Radio Hill processing plant we are well positioned to take advantage of exploration success.
“With this strong start, we’re very eager to get back out on the ground for our next stage of drilling to push further into these high-grade zones and accelerate building the Whundo copper resource base.”
