Mutli-mineral explorer White Cliff Minerals Ltd (ASX:WCN) has discovered a new high-grade silver zone only 550 metres from historic mines at its Great Bear project in Canada, with assays from the area including grades of 7.54% silver (Ag) – or 75,439 grams per tonne, 5.35% Ag (or 53,506g/t) & 13.6% copper (Cu).
The zone – dubbed ‘Slider’ – measures at least 1.5 kilometres by 1.5 kilometres and is approximately 550 metres along strike from two historical producing underground silver mines which produced 34,200,000 ounces of refined silver.
White Cliff has also drawn attention to some of the geological features of Slider, including a newly identified east-west structural trend which extends across 450 metres in strike length, and has returned assays grading up to 904 grams per tonne of silver, 6.5% of copper and 8.1% of zinc.
Additionally, the company has identified a westerly extension of the mines themselves which includes a zone of native silver bearing breccias.
Managing director Troy Whittaker said the cluster of discoveries was notable given the early stage of exploration which White Cliff was engaged in.
“Well, this not something you see every day, let alone to find on surface during a maiden field program – possibly the highest-grade silver results published in recent history,” he said.
“It’s remarkable that the team has now delineated a total of six high grade copper, gold and silver mineralised districts at Great Bear.
“Results to date have included massive, mineralised contents of 42.6% Cu, 42.2% Cu, 39.5% Cu, 38.2g/t Au, 29.7g/t Au and 716g/t Ag and, now, those results have now potentially been
outshone by this silver discovery.”
He said that building on the Slider discovery would be the focal point now, given its size.
“Amazingly, the 1.5 x 1.5 km Slider District remains underexplored. Given these results – there is a lot of upside for additional high grade silver structures to exist,” he said.
White Cliff has been trading at 1.4 cents.
