Geology Comments

Dec 07, 2005 (A Wilson) - A conjugate pattern is apparent from the distribution of th quartz veins, but there is little apparent deformation of the host rocks. The veins have been reported as braided with a pinch and swell appearance.

Lithology

Lithology Comments

Dec 07, 2005 (A Wilson) - The #1 Vein is hosted in massive mafic flows within a pillowed flow sequence at surface, but with depth, passes into metasediments. Associated with the vein on surface is a felsic dike which has been described as a porphyry, but the most conspicuous megacrystic grains are of small anhedral hornblend rather than the large subhedral feldspars which are prevalent elsewhere on the property Mineralization is closely associated with the porphyritic felsic dike and silicified porphyry can also host some mineralization. Metasedimentary rocks are conspicuously absent in the waste rock pile.

Mineralization

Mineralization Comments

Dec 07, 2005 (A Wilson) - Mineralization occurs in hairline fractures in the altered wall rocks filed with euhedral to subhedral pyrite. The best gold grades occur where the vein cuts through metavolcanics. The vein is a coarse-grained, glassy white to clear quartz which is cut by secondary veins (<2mm) of fine-grained sulphides. These veins are up to 5 m thick, but grade laterally into a stockwork of veinlets. Coarse gold occurs in globs within the veins, close t the footwall or in leaf form on slickensided surfaces. The most spectacular description is of solid gold, 2 inch diameter times 1/2 inch thick nuggets. Assays from the veins at the time of discovery averaged 0.6 g/t Au and the adjacent wall rock returned 12.39 g/t Au. The veins at the No 1 Shaft are the #1 Vein (8.6 g/t Au across 109 cm), the #17 Vein, the #18 Vein (9.9 g/t Au across 74 cm) and the #19 Vein (5.1 g/t Au across 112 cm). Underground sampling of the #1 vein in 1933 averaged 2.7 g/t Au across an average width of 2.4 g/t. Grab samples taken by the OGS in 1970 returned values of 5.5 g/t Au and 6.5 g/t Au . A sample of the muck pile taken by the OGS in 1993 returned a value of 3.02 g/t Au and 1.00 g/t Ag.
