WESTERN COPPER AND GOLD INTERSECTS 2.53% CUEQ OVER 65.8 M AND 1.01% CUEQ OVER 289.6 M AT CASINO
Western Copper and Gold Corp. has released assay results from the initial nine holes of the 2021 diamond drilling program at its wholly owned Casino project in Yukon, Canada. The program, developed with input from Rio Tinto, comprised a total of 6,074.97 metres in 22 holes.
Highlights
- The importance of the core of the deposit to the overall resource at Casino ("Deposit Core", see news release dated February 2, 2021) was reinforced by long intercepts of above-resource grades in both the Leached Cap and Sulphide zones (Table 1):
- DDH21-02, -04, and -06 encountered over 200 metres of 0.86%, 0.97%, and 0.81% CuEq1, respectively, in the Sulphide zone within the Deposit Core.
- DDH21-02 and -04 intersected over 100 m of higher-grade Leached Cap in the Deposit Core with grades of 0.47 g/t and 0.61 g/t Au, respectively.
- DDH21-07 and -09 intercepted above-resource grades in the Sulphide zone just east of the Deposit Core:
- Hole DDH21-07 returned a 289.6 m intercept of 1.01% CuEq1 from 36.6 m . This intercept confirmed the higher-grade nature of the upper zones of sulphide mineralization within previous holes and extended those higher grades zones by approximately 100 m of true vertical depth.
- DDH21-09 returned a 65.8 m intercept of 2.53% CuEq1 from 10.6 m , one of the highest-grade intercepts drilled to date on the property.
Summary
The results from these nine drill holes essentially confirmed or, in some cases, improved upon historical drilling in the area. This confirmation, and in some cases an increase in grades and/or extension of higher-grade zones, are important achievements of these initial results.
At Casino, higher grades are hosted mostly by intrusive breccias and, in the Deposit Core, also by Patton Porphyry intrusive rock. DDH21-07, -08, and -09, which were drilled east of the Deposit Core, indicate that higher grades also occur in the Dawson Batholith proximal to the brecciated rocks.
"The results from the first holes drilled as part of the 2021 drilling campaign clearly outline the importance of the Deposit Core at Casino.", said Paul West-Sells, President & CEO, "Intercepted grades encountered in and around this area are some of the highest drilled to date on the property, and importantly occur at the top of the Sulphide zone in these areas, representing material that will be mined early on during operations."

Carl Schulze, P.Geo. is the qualified person responsible for the execution of the Casino Project exploration program and the preparation of the technical information in this news release.
QA/QC including assurance of chain of custody has been implemented. Split core samples are prepared and analyzed by ALS Geochemistry. Prepared samples are initially run using a four acid digestion process and conventional multi-element ICP-AES analysis. Additional assaying for total copper and molybdenum is run using a 4-acid digestion AES or AAS method to a 0.001% detection limit. Gold assays are run using 30-gram sample fire assay with an AA finish to a 0.005 ppm detection limit, with samples greater than 10 ppm finished gravimetrically. The QA/QC procedure involves regular submission of Certified Analytical Standards and property specific duplicates.
