West Mining Completes 7 Diamond Drill Holes On The Kena Copper Zone, Kena Property, BC
Vancouver, B.C. – November 10, 2021– West Mining Corp. (“West” or the “Company”) (CSE: WEST) (OTC: WESMF) is pleased to report the completion of an initial 7 diamond drill holes on the Kena Copper Zone area of its 100% owned Kena gold and copper project in southeastern British Columbia. All of the holes intercepted strong zones of alteration and silicification along with variable pyrite-chalcopyrite mineralization throughout.
The Kena Copper Zone is identified by a significant copper geochemical anomaly associated with a strong zone of high chargeability, lying within mafic volcanic and subvolcanic diorites of the Rossland Group Elise Formation. The soil anomaly has dimensions of 2.5 kilometres in length by an average of 450 metres in width as outlined by the 300 ppm copper contour. Within the anomaly there are numerous soil samples assaying between 1,000 and 5,000 ppm copper. Between 1981 and 2010, a total of nine wide spaced historic drill holes tested the copper target. Broad zones of low grade copper mineralization (0.1 to 0.5% copper) were intersected by this historic drilling.
Volcanic rocks in the Kena Copper Zone are comprised of andesitic to basaltic crystal tuff, lapilli tuff and flows. The area is characterized by the dominant northwest-southeast steeply dipping foliation seen across the northern half of the Kena property. Mineralization in the copper zone appears to conform to this fabric in the main body of the copper porphyry. Cutting this fabric is a series of quartz veins roughly perpendicular to the NW-SE trend. In the core, many of the veins are quartz with pink calcite or amethyst, strong clots of chlorite and abundant coarse pyrite, chalcopyrite and malachite. Malachite is often found on fractures even at depths greater than 100 metres. These late extensional veins were targeted in several historic workings found along the northeastern side of the main copper porphyry body. These workings include 5 adits, 2 shafts and several pits.
All drill holes, with the exception of KC21-03 and KC21-07, are angled at -50o dip with azimuths of 040o in order to cross the foliation controlling mineralization at close to true width angles. The other two drill holes are vertical holes to facilitate deeper drilling depths.
“We are excited to be drilling the under-explored robust Kena Copper Zone. Core logging has shown broad zones of visible copper mineralization throughout the drill holes and we are anxious to receive the assay results,” stated Nicholas Houghton, President and CEO. “Data we have shows previous drill programs alluded to a copper porphyry deposit but it was never persued. I believe the initial holes described below show a strong probability that our geological team interpreted the information correctly.”
KC21-01, drilled to 122 metres, intercepted mafic volcanics, crystal and lapilli tuff throughout. This hole goes through wide rubbly chloritized zones and ended in very fractured blocky rock. 1% pyrite occurs with zones of disseminated and banded pyrite up to 10%, locally. From 44.3-53.75 metres, there is up to 1% finely disseminated chalcopyrite.
KC21-02, drilled to 201.37 metres and KC21-03 drilled to 670.73 metres, were drilled from the same pad and both intersected the top 50 metres of the foot wall of the interpreted porphyry copper zone that strikes NW-SE, and dips steeply to the SW. This is seen as a 50 metre wide (true width) zone of strongly silicified mafic volcanics with 1-20% pyrite and trace-3% chalcopyrite. The strongest mineralization is at the top of the hole indicating the need to step back to the southwest to intersect more of the mineralized zone. Hole KC21-03 intersected intermittent silicified zones with strong pyrite and sporadic chalcopyrite down to 650 metres.
KC21-04, drilled to 265.6 metres, is the eastern most hole drilled. The top 114 metres (true width) of this hole is moderately to strongly silicified with 1-15% pyrite and tr-2% chalcopyrite disseminated throughout and along fine fractures. The sulfides are generally extremely fine grained suggesting there may be more present than is being estimated.
Hole KC21-05, drilled to 236.0 metres, was drilled from the same pad as historic hole 10CK-01 which was a vertical hole that intersected wide zones of copper mineralization to 250 metres depth. The top 158 metres of KC21-05 is dominated by moderate to strong silica-carbonate alteration with 2-15% pyrite and trace to 3% chalcopyrite disseminated very finely and in fractures and veinlets.
Hole KC21-06, drilled to 367.0 metres, is a due diligence twin of 1990 historic drill hole K90-4, which intersected wide zones of copper mineralization to its total depth at 391.95 metres, including 57 metres of 0.27% Cu, 18 metres of 0.41% Cu and 12 metres of 0.35% Cu (BC Assessment Report 20894; Lewis, W.J and Silversides, D.A). KC21-06 intersected several zones of mineralization: 55-67 metres with 5-10% pyrite and 0.3-0.5% chalcopyrite; 100-224 metres of strong quartz-carbonate alteration with 5-20% pyrite and 1-3% chalcopyrite; 291-332 metres with fine chalcopyrite up to 3%. A 40 centimetre true width quartz vein at 314 metres has 15% coarse chalcopyrite. As with other holes, the sulfides are generally extremely fine grained and may be underestimated.
Hole KC21-07, drilled to 509 metres, is a vertical hole drilled from the same pad as KC21-06. It intersected strong mineralization in silicified zones from 103-195 metres and 200-235 metres with 3-15% pyrite and trace to 3% chalcopyrite. Very fine grained disseminated chalcopyrite is seen throughout the entire depth of the hole as well as semi-massive pyrite-chalcopyrite-quartz-carbonate veinlets running at low angle to core axis.
