Shares in White Cliff Minerals (ASX:WCN) have jumped 24% as the company flags hitting copper rock chips with extremely high grades in Canada.
While rock chips are often high in concentration – consider that a rockchip will only be visible during an on-the-ground campaign due to their ‘shiny’ nature – White Cliff’s rock chip grades go well above what many other projects report.
Also consider that White Cliff’s latest samples were taken from metal vein systems spotted by geotechs on-site the company’s Rae project.
As for results, the company unveiled the following rock-chip sample copper and silver grades on Friday from the Don prospect, an area of around 2sq.km:
- 64% copper and 152g/t silver
- 62% copper and 162g/t silver
- 50.5% copper and 102g/t silver
- 43.7% copper and 109g/t silver
- 39.7% copper and 91g/t silver
At the Pat prospect – just over 4km along strike from Don, and with samples pulled from an ~600m area of visible outcrop – White Cliff reported on Friday:
- 55% copper and 37g/t silver
- 46% copper and 46g/t silver
- 44% copper and 32g/t silver
- 41% copper and 34g/t silver
- 39% copper and 34 g/t silver
All in all, these results leave White Cliff’s geotechs hopeful for “very significant deposits of sedimentary hosted copper.” Part of that is because these could be the highest rock chip grades ever reported.
“Having undertaken an extensive internet search, it is my belief that these results are the highest ever recorded copper assays from a representative rock chip sample anywhere in the world and in fact are approaching the stoichiometric maximum copper can reach in an ore forming mineral,” White Cliff Minerals MD Troy Whittaker said.
“The results also demonstrate the deep plumbing, copper rich fluids & fertile nature of the host rocks of basal part of the Rae sedimentary sequence and provide longer-term opportunities for not just bulk tonne sedimentary hosted copper but potential for direct shipping of a high-grade copper concentrate.”
WCN last traded at 2.6cps.
