Dec 07, 2005 (P Beach) - The radiometric anomalies are located at or near the sheared contact between Keweenawan diabase dikes and Early Precambrian granite. The G showing located in the south part of the property consists of a shear zone at the contact of the diabase and the granite. The shear zone, from a few inches to 5 feet in width, consists of thin veins and a fine network of fractures which are filled with hematite and calcite. Uranium bloom occurs on the surface. A sample fro this showing registered 22.8 on the geiger counter. The A-West showing consists of visible pitchblende exposed in a trench in the diabase about 3 feet from the granite contact. A geiger count of 8.1 was obtained over the showing. The A-North showing consists of two zones where a geiger count reached 15. One zone is in diabase approximately 15 feet from the south contact while the other zone is in the granite about 20 feet north of the diabase contact. (OGS 1983 MDC 25 P 46-47).
