GreenTech sees growth on horizon at Whundo with up to 4.6pc copper assays

GRE reports up to 4.6% copper at Whundo project in Western Australia
Results highlight potential for resource expansion
Company now planning follow-up drilling

Special Report: GreenTech Metals has flagged grades up to 4.6% copper in latest assays from its Whundo project in WA, highlighting the potential for resource growth.

The project already hosts an initial resource estimate of 6.2Mt at 1.12% copper and 1.04% zinc, with the results from this 1,710m RC program indicating the potential for significant resource expansion below the six known mineralised shoots.

Results for the Austin and Ayshia mineralised shoots have confirmed the continuity of copper mineralisation down dip beyond 230m depth, including:

16m at 1.2% copper, 0.12% zinc, 0.035g/t gold from 230m, including 8m at 1.5% copper, 0.21% zinc, 0.039g/t gold from 230m (Austin); and
10m at 1.2% copper, 1.2% zinc, 0.09g/t gold from 260m, including 3m at 3.1% copper, 2.6% zinc, 0.23g/t gold from 261m (Ayshia)

Collectively, these results point to the continuation of copper-zinc mineralisation at depth within the respective moving loop electro-magnetic (MLEM) conductor footprints and highlights the significant potential to expand the resources at Whundo by drilling.

In addition, at the Shelby shoot, a large conductor plate (>400m x 50-100m) modelled from a Down Hole Electromagnetic (DHEM) survey on drill hole 24GTRC005 has returned a conductive response over 15,000 siemens, greater than previous responses of known mineralisation associated with Shelby.

Further drilling could increase resource

The close spatial relationship between the known mineralised shoots with respect to plunge and nature and thickness of mineralisation suggest these are all part of a large VMS type mineralising event, which remains open along strike and at depth, the company says.

“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,” GreenTech Metals (ASX:GRE) executive director Tom Reddicliffe 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’ (ASX:ARV) 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.”

Planning is underway for a follow-up drill program aimed at continuing to test the depth potential of the mineralisation at Austin, Ayshia, Yannery and Shelby.
