1949-1950: Prospecting, trenching, 6 mile road from Highway 17 and a powerline were constructed.
1951: An adit was driven with 1628 feet of drifting along the dike and the fault. Ten crosscuts totalling 192 feet and a 164 foot raise were driven.
Mineralization occurs near the south contact of a Keweenawan diabase dike with Early Precambrian granite. This dike strikes N80W and dips steeply to the north. The McCarthy fault cuts off the dike to the east. The radioactivity is found mostly in a brecciated zone 12 to 15 inches wide within the diabase dike, parallel to and within several feet of the south contact. The fractures are filled with calcite-hematite gangue and pitchblende.
