Dec 07, 2005 (K R Kettles) - GEOLOGICAL DESCRIPTION: Showings on this former Advance property are quite similar to the main showings, and the old Heath property (TD 17) to the north. Gold occurs in narrow quartz veinlets containing visible gold and in pyritic zones in a dark coloured 'altered rhyolite?' (Thomson, 1945). The area of the main showing is underlain by felsic tuffs, by a coarse felsic breccia with fuchsitic matrix, that continues into this property from TD 17, and by lenses of carbonatized mafic or ultramafic rocks (Riley 1978). Thick chert-carbonate sediments lie to the southwest, stratigraphically above the main showings. As at TD 17, auriferous quartz veinlets occur at large angles to bedding and the best gold mineralization occurs near the coarse felsic breccia unit. Several easterly trenches were put down on the chert-carbonate sediments and these rocks may also carry gold. DEPOSIT DESCRIPTION: Irregular quartz veins and pyritic gold-bearing rock occur in felsic volcanic rocks over a 350 m strike length.

Oct 30, 2020 (K R Kettles) - MDI1 DATA: GRADE 1929: UP TO 0.52 OPT AU/30 CM Gold occurs in irregular veinlets and pods of altered rock over an extensive area. Robinson (1929) reports values of up to 0.52 oz/ton (17.828 g/tonne) Au over 30 cm.
Dec 07, 2005 (K R Kettles) - The breccia is altered to fuchsite. The 'altered rhyolite?' is carbonatized and silicified. Some tuff is 'waxy' or sericitic.
