Geology Comments

Dec 07, 2005 (A Wilson) - The fine-grained nature of the host rock in the vicinity of the mineralized quartz vein, in contrast to the more normal coarse-grained nature of the granodiorite suggest the possibility of cataclastic milling.

Lithology

Lithology Comments

Dec 07, 2005 (A Wilson) - The host rock is a siliceous green, fine-grained granodiorite with smoky grey, irregular quartz grains. The green colouration is probably due to a weak, pervasive chlorite alteration.

Mineralization

Mineralization Comments

Dec 07, 2005 (A Wilson) - The showing consists of relatively small amounts of irregular quartz veins in a shear zone. The quartz is very coarse-grained and white to clear together with some disseminated pyrite. In addition, there are locally massive pyrite seams up to 2 cm thick, but typically <5 mm within the quartz veins. In these seams, the pyrite is coarse grained. In addition to the sulphides, sparsely disseminated pyrite also occurs in the sheared granodiorite host rock and in massive stringers along shear zones without quartz. Grab samples collected by the OGS in 1980 returned values of 1.7 g/t Au. Grab samples collected by the OGS in 1993 returned values of 0.76 g/t Au, 5.0- g/t Ag, 0.18% Cu; 0.47 g/t Au, 2.6 g/t Au and 0.03% Cu.

Geologist: A Wilson

Notes: W. S. Savage visited the property in 1954 (PRECIS) On the north shore of Clam Lake, about 800 feet to the northwest across the lake from the peninsula, there is a water-filled pit which was sunk on a quartz vein which Laird considered to be the extension of the vein in the first pit on the main showing. Fragments of the quartz vein on the dump are heavily mineralized with white pyrite. The country rock is a blocky, jointed grey granite.
