WESTERN COPPER AND GOLD PROVIDES DRILL PROGRAM RESULTS FOR CASINO
Drill Program
The Drill Program included a diamond drill hole (DDH22-01) targeting a deep-seated magnetotelluric ("MT") geophysical anomaly indicating potential for a conical mineralized zone directly southeast of the Casino Deposit core zone. Additionally, 23 short diamond drill holes totaling 853.71 m, and 9 combined sonic/diamond drill holes totaling 364.43 m, were completed on various targets for geotechnical and water-monitoring purposes. The program also included 34,387 m of drill core scanning utilizing the GeologicAI scanning device built by Enersoft Inc.
DDH22-01 was collared along the Casino deposit's southeastern limit (UTM NAD 83, Zone 7V coordinates: 611160E, 6958125N, elev. 1,236 m) and drilled at an azimuth of 170degree and dip of -80degree to a depth of 1,008 m. Downhole measurements were made at regular intervals to verify that the hole was on target and successfully intersected the projected MT feature. The top of the anomaly was encountered at approximately 800 m total depth.
The lithology of the entire drill hole was dominated by Dawson Range granodioritic intrusive rocks, crosscut by only a few dykes, interpreted as members of the younger Patton Porphyry intrusion. Intrusive Breccias, the principal host rock of the Casino deposit, were not intersected. Phyllic and argillic alteration was logged at shallow depths along the deposit margin, and propylitic alteration dominated within and directly overlying the anomaly. Elevated copper, gold, and silver values were exclusively hosted by thin pyritiferous structural zones throughout the drill hole. The top of the sulphide zone was encountered at approximately 100 m depth; the percentage of sulphides decreased with depth, apart from those hosted by the thin structures. Select intervals are shown in the table entitled "Select intervals of DDH22-01."
