Exploration works conducted by GreenTech Metals such as reverse circulation drilling and DHEM surveys have identified two highly compelling drill targets at the Company’s Whundo copper-zinc project in the West Pilbara.

GreenTech (ASX:GRE) started drilling at Whundo straight after listing earlier this year and since the commencement of these exploration activities, has undertaken more than 5,000m of drilling.

The company has also declared a mineral resource estimate at the Ayshia prospect and increased the contained metal for the Whundo Project by 54% since listing on the ASX.

As part of the latest round of drilling, a DHEM survey was completed for the first time at Shelby target highlighting two large conductors at depth – the upper conductor, which is coincident with an intercept of 11.25m at 1.6% copper from 391m, and the lower conductor which has a large areal extent and remains untested.

GRE says hole 22GTR034 drilled earlier this quarter appears to have intersected the edge of the lower conductor target, with downhole EM highlighting a significantly stronger (~17,000-30,000S) off-hole downdip conductor.

The company’s view is this may represent a thicker and/or higher-grade zone of copper mineralisation.

The new strong conductor – three times the strength of the previously reported conductor targeted in the drilling – is interpreted as a down dip extension to the mineralised zone intersected in holes 22GTRC024 and 22GTRC033 and will be followed up in the next drill program.

The right location for drilling and exploration

“These conductor plates… give us confidence that we are targeting the right location for further drilling and exploration,” GRE executive director Thomas Reddicliffe says.

“We are very encouraged by these most recent results from both the Austin and Shelby targets and believe that these may represent discrete mineralised centres typically associated with VMS clusters and therefore have the potential to add to the Whundo resource inventory.”

Looking ahead

The Austin and Shelby copper-zinc prospects are in addition to the already known cluster of discrete copper-zinc deposits at Whundo constrained within a 500m wide zone over a strike length of 2km.

GreenTech plans to carry on with its methodical exploration of these two prospects in the new year aimed at identifying the high-grade cores associated with these deposits.

The company is confident it will be able to increase the Whundo mineral resource, which stands at 93,000t of contained metal, and potentially start mining studies in the new year.
