Aug 17, 2017 (A Wilson) - On RL458 a vertical shaft, 64 ft. deep, approximately 75 ft. east and 160 ft. north of the No. 3 post was put down on a series of calcite stringers striking N67ºE. Cobalt bloom was found in this fractured rock. At an 8-foot depth, these veins dipped out of the shaft; at 40 ft. another calcite vein was encountered. This second vein assayed 20 oz/t. The Nesbitt shaft was put down approximately 260 ft. northeast of the first shaft. The Nesbitt shaft is reported by Mr. Coo to be just south of highway 567. The shaft was put down on a series of northwest-striking quartz-calcite stringers carrying cobalt bloom

Mar 25, 2013 (A Wilson) - Cobalt bloom was observed in the vicinity of the calcite veins. A sample collected from one of the veins at the 8 foot depth returned an assay of 20 oz/t Ag. Assays from a pit on the claim returned 46 oz/t Ag.
