Greentech Metals says RC results received to date further highlight the exceptional copper and zinc grades at the Whundo copper-zinc project, where mining activity took place as recently as 2006. 

Best results include:

  • 32m at 2.43% copper from 75m, including 17m at 4.37% copper and 0.46% zinc from 90m, including 7m at 7.83% copper, 0.64% zinc and 0.26g/t gold from 95m (RC0051);
  • 62m at 1.12% copper, 1.36% zinc and 0.36g/t gold, including 19m at 1.6% copper, 2.27% zinc and 0.51g/t gold from 21m (RC0071);
  • 45m at 1.15% copper and 2.6% zinc from 23m, including 12m at 9.17% zinc, 2.34% copper and 0.62g/t gold from 52m (22GTRC0081);
  • 8m at 2.65% copper, 0.64% zinc and 0.11g/t gold from 141m (22GTRC017); and
  • 10m at 2.85% copper and 0.96% zinc from 162m (22GTRC023).

Greentech Metals (ASX:GRE) says the drilling confirms that the high-grade copper and zinc mineralisation at the project persists down plunge and beyond the current resource envelope.

Today’s exceptional results have been well received by the market, with an over 145% increase in share price within the first few hours of trading, furthermore showing the rare nature of these grades.

Deeper intersections mean resource expansion potential

Notably, Volcanic Massive Sulphide (VMS) deposits often occur in clusters and there are three VMS prospects known within 1500m of the Whundo mine.

The company is confident that the deeper intersections of copper-zinc mineralisation increase the potential for resource expansion at the project.

“Results from the initial laboratory assays received to date confirm the high-grade tenor of copper and zinc mineralisation at Whundo which is at the core of a much broader copper and zinc mineralised system,” executive director Thomas Reddicliffe said.

“Drilling has demonstrated that the mineralisation at Whundo remains open at depth and with grades persisting.

“This and the identification of two additional mineralised horizons provides further impetus for the company to build upon the known resource.”

Gold grades an added credit

The company says the gold grades of up to 3.34g/t accompany the higher-grade copper zones along with cobalt, and – based on further metallurgical test work – it is likely that both the gold and the cobalt will enhance the economics of the project.

“Pleasingly, the Whundo mineralisation carries notable gold grades, which as a credit, further enhances the potential economics of the project,” Reddicliffe says.

Assay results for three holes drilled at Whundo, and seven holes drilled at the nearby Ayshia deposit expected in the coming weeks.

“Once the balance of our assay results has been received, we will incorporate this new information into the existing JORC 2012 Indicated Resource at Whundo, which currently sits at 2.7Mt at 1.14% copper and 1.14% zinc, and which forms part of the larger Whundo/Ayshia Indicated and Inferred Mineral Resource of 3.6 Mt at 1.2% copper and 1.4% zinc,” Reddicliffe said.
