Jul 15, 2024 (Nazha Sabiri) - This property contains several mineral veins, numbered 1 to 6. These veins are located in concession 10, lots 13 and 14. Vein #1 (Mispickel Vein): This is the most significant vein in terms of historical production. It's 366 meters long, 3.7 meters wide, and oriented with a strike of 20 degrees northwest and a dip of 60 degrees west. Vein #2 (Free Milling Vein), is a vein of massive quartz, 1.5 to 3.0 m wide, strikes 75 degrees NW, and dips 60 degrees to the south; best gold assays from this vein are: 2.7 oz/ton gold over 2.4 m in Shaft #1, 3.77 oz/ton over 3.0 m and 0.40 oz/ton over 1.80 m in Shaft #3. Vein #3, no dimension or orientation reported, veins assayed 0.15 oz/ton gold over 1.5 m and 0.31 oz/ton over 1.5 m. Vein #4 is 91.0 m long with best gold assay of 0.57 oz/ton over 2.9 m. Veins #5 and # 6 are sheared quartz-carbonate veinlets that run parallel to Vein #2. Gold values range from 0.01 oz/ton to 0.05 oz/ton over 1.5 m to 5.5 m in Vein #5 and no significant values were encountered in Vein # 6 (File 31C11SW0020).
