Greentech’s Whundo copper-zinc project is looking more attractive than ever after drilling of the new Austin prospect intersected a thicker extension of a previously drilled zone.

The follow-up reverse circulation drill hole was designed to test the very strong conductor plate modelled from the down-hole electromagnetic survey completed on hole 22GTRC23, which returned a 12m intercept grading 2.5% copper from a downhole depth of 161m.

This returned a 20m intercept of copper-zinc mineralisation in hole 23GTRC001, which not only extends the previously drilled zone down-dip but also shows the mineralised zone thickening at depth..

Adding further significance for Greentech Metals (ASX:GRE), this thickening mirrors the overlying Whundo resource and is consistent with Austin being a separate mineralising event.

It also demonstrates the resource potential of this deeper zone and indicates that mineralisation at Whundo is not as limited as previously thought, which paves the way for a move towards mine study development work.

Methodical follow-up

“This has proved to be an important follow-up drill program for the company and is a continuation of the methodical follow-up of the large Austin conductor anomaly,” executive director Thomas Reddicliffe said.

“This deeper mineralised zone which occurs beneath and down dip of the currently larger known Whundo resource now appears to have the potential to significantly increase the resource.

“These results also give us confidence that there is still much to be found within the large conductive area between Whundo and the Yannery prospect.” 

Upcoming activity

Greentech plans to carry out a follow-up DHEM survey soon to further define the extent of this mineralised zone.

Assays are also pending for the follow-up hole.
