Mar 31, 2022 (Therese Pettigrew) - The Weekly Herald (January 25, 1890) reported that the company had discovered free milling gold ore from a vein averaging 100 feet wide and extending for over half a mile. The average of different assayers was about $9 a ton (approximately 0.43 oz/t Au). The Black Fox shaft and the three stripped areas located nearby represent part of a massive quartz stockwork system Quartz veins up to 30 feet wide with latticed stringers dominate the outcropping areas. The dominant vein orientation varies between 090 and 120 . The quartz is of the white, milky variety which generally lacks sulphides except for patches where pyrrhotite and minor pyrite is present. Wallrock inclusions are occasionally found in the quartz veins. Wall rock alteration is minimal and indicates a relatively cool intrusion temperature. A strung structural control of the vein system and stockwork is indicated by the orientation of the main veins which are parallel to the early shears. Four samples were taken in the general vicinity of the Black Fox shaft and assayed for gold. These assays all indicate <0.002 oz/T gold for these samples (Assessment report 52F09SE0027).
Mar 31, 2022 (Q Unknown) - BEST ASSAY: 0.5 OPT AU (WEEKLY HERALD 1890).
