K92 drilling intersects high-grade copper and gold in Kora Extension Discovery Zone
By: Kevin Silva
K92 Mining Inc. (K92) (TSX.V: KNT) has announced very high-grade copper and gold assays, encountered in the first holes drilled to follow up on the recently announced Kora extension discovery. Indicative of the size potential of Kora that has mining investors excited, note that the extension discovery was made approximately 500 metres along strike, and 150 metres downdip from the currently defined Kora inferred resource.
Results from K92 include 3.4m at 9.94 g/t gold, 55 g/t silver and 5.97% copper (19.78 g/t AuEq) in drill hole KMDD0016, and 4.45m at 9.2 g/t gold, 7.71 g/t silver and 0.51% copper (10.18 g/t AuEq) in drill hole KMDD0015.
Additional to these high grade drill results, K92 also reported high-grade assay results from Kora face sampling. Face sampling and mapping has at times recorded massive chalcopyrite, with the best intersection recorded to date being 0.5m @ 475.28 g/t Au, 161.1 g/t Ag and 7.25% Cu. A photograph showing some of the massive chalcopyrite recorded in the Kora development is shown above (sampling of this face averaged 4.1 metres at 8.86 g/t Au, 20.9 g/t Ag and 1.14% Cu).
John Lewins, K92 Chief Executive Officer and Director, states, “The results from the first four diamond holes drilled from underground, covering a strike length of some 100 metres, have confirmed our interpretation that the Kora Vein system extends some 500 metres to the north of the existing inferred resource. Further, face sampling to-date has consistently recorded the presence of the vein system, with some extremely high-grade zones of mineralization encountered.
“We are continuing to drill this northern extension, both along strike and up-and-downdip, as well as developing along strike in both a southerly and northerly direction. These results, combined with the excellent results achieved from processing the first part of the bulk sample from Kora give us increasing confidence in the immediate potential of this northern extension.”
While conducting ongoing drilling and face sampling, the company also completed the mining of an initial bulk sample at Kora, having mined in excess of 2,000 tonnes from a four-metre-by-four-metre horizontal development, extending north and south from the previously reported initial cross cut intersection of the Kora Vein.
The first 800 tonnes of mined material were processed, with results significantly better than anticipated, with gold recovery of 92.4% and copper recovery in excess of 95%. This is above the 91.5% recovery assumed in the company’s PEA, and even more impressive when considering that this is the first batch of material treated, and was achieved without a gravity gold circuit. It is the company’s expectation that further optimization should improve on this performance as will the introduction of a gravity gold circuit.
