Dec 07, 2005 (P Beach) - Pitchblende veins occur in tension cracks within Early Precambrian granite near its sheared contact with the footwall of a Keweenawan diabase dike. This dike strikes N80W and dips 70 N. The pitchblende is associated with calcite and hematite in veins usually 1 inch wide or less. Some stringers are 6 inches wide or more. The pitchblende-bearing fractures are concentrated in two zones. The west zone extends 245 feet east from the lake, and the east zone, 230 feet to the east, is 85 feet long. They both strike N80W and dip 70N. (OGS 1983 MDC 25 P 46).
