West Mining Corp. (CSE: WEST) (OTC: WESMF) is pleased to announce the analytical results from their initial seven diamond drill holes on the Kena Copper Zone area of its 100% owned Kena Gold and Copper Project in southeastern British Columbia. All 7 holes intercepted strong zones of alteration and silicification along with variable pyrite-chalcopyrite mineralization throughout.
The diamond drill holes targeted copper-gold porphyry style mineralization in the Kena Copper Zone, readily identified by a 2,500 x 1,000 metre strong copper soil geochemical anomaly. The Kena Property hosts a large porphyry system consisting of a gold rich core surrounded by a broad halo with a copper-gold signature, as illustrated by the gold and copper soil geochemical maps below.

Within the central core area of the Kena Property, the Gold Mountain and Kena Gold Zones contain a combined resource estimate with 561,900 ounces gold indicated and 2,773,100 ounces gold inferred (Bird, 2021; NI 43-101 Technical Report on the Kena and Daylight Properties; see News Release dated May 11, 2021). The gold zones are opened ended and have expansion potential the north, west and south – where historic drilling in the South Gold Zone intersected 0.9 g/t gold over 90 metres (BC ARIS Report 27240).
Adjacent to the gold resource area and gold geochemical anomalies are large coincident induced polarization chargeability and copper soil geochemical anomalies. Drilling earlier in 2021, to the northwest near the Starlight showing, discovered a new zone which returned a 53 metre drill intercept which averaged 0.51% copper equivalent (see News Release dated January 12, 2022). The Dighem copper anomaly, immediately to the east of the Gold Mountain Zone will be drill tested as part of the 2022 exploration program. This anomaly was first identified during an airborne magnetic survey (flown by a company known as “Dighem”) and later followed up with soil geochemistry and induced polarization ground surveying.
2021 Diamond Drilling – Kena Copper Zone
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. Prior to West Mining acquiring the property, 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.
Analytical results from West’s 2021 diamond drilling in the Kena Copper Zone have now been received. A total of 7 holes were drilled over a 600 metre strike length. All drill holes, with the exception of KC21-03 and KC21-07, are angled at -50o or -60o 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.

*CuEq % was calculated using the following formula: (Cu(%) x 22 x 4.5) + (Au(g/t) x 0.03215 x 1880) + (Ag(g/t) x 0.03215 x 23) / (22 x 4.5), based on: Cu US$4.50/lb; Au US$1,880/oz (US$60/gram); Ag US$23/oz ($US0.74/gram); 1 tonne = 2,205 lbs; 1% = 22 lbs; 1 gram = 0.03215 oz.
Note: Intervals in holes KC21-01, 02, 04, 05, 06 represent approximate true widths. Intervals in holes KC21-03 and 07 represent approximately 120% of true widths.

“We are excited by the very broad intersections of copper mineralization from our initial 7 drill holes in the large and robust underexplored Kena Copper Zone. We are very much looking forward to our 2022 exploration season where we will continue drilling of the copper anomalies, as well as expanding the gold resource,” states Nicholas Houghton, West Mining President and CEO.
Prior to continued drilling of the copper porphyry zones, a detailed magnetotellurics survey will soon commence and this new data will be modelled and merged with earlier induced polarization surveying to allow better visualization of the mineral phases for drill targeting within this very large alteration system.
Quality Assurance/Quality Control
West’s QA/QC procedures include one each of blank, field duplicate and standard inserted into the sample stream for every 20 drill core samples. Core samples are split, bagged, zip-tied and trucked to Bureau Veritas Commodities Canada Ltd. (“BV Labs”) in Burnaby, British Columbia for analyses. The field inserted standards (certified reference materials) and blanks were purchased from CDN Resource Laboratories Ltd. of Langley, British Columbia.
Samples are analyzed at BV Labs facilities for gold by fire assay with an atomic absorption finish and 48 additional elements using a multi-acid digestion with an ICP-ES finish.
BV Labs are registered to ISO 9001:2008 and ISO 17025:2017 accreditations for laboratory procedures. In the laboratory, blanks (analytical and method), duplicates and standard reference materials are internally inserted in the sequences of client samples. Using these inserted quality control samples each analytical batch and complete job is rigorously reviewed and validated by BV Labs prior to release.
The QA/QC results confirm acceptible analytical accuracy and precision.
