Dec 07, 2005 (K R Kettles) - GEOLOGICAL DESCRIPTION: At this locality a unit of chert-carbonate chemical sediments 100 to 300 m thick strikes northwesterly and dips steeply. The sedimentary unit is underlain to the northwest by felsic tuff. Felsic tuffs are interlayered within the sediments and the overlying rocks. Gold occurs at various stratigraphic levels in the chemical sediments, mainly associated with disseminated pyrite and scattered pyrrhotite. The diamond drill program that identified this gold was carried out across the east-west regional foliation, and in the underlying tuffs as well as in the chemical sediments, but drill logs are available only for holes on the east boundary of KRL 509638. On the basis of the distribution of this drilling (Heath Gold Mines Limited, 1946) it is likely that some gold was encountered in felsic volcanics as well as in the chert-carbonate rock. DEPOSIT DESCRIPTION: Pyrite layers in chemical sediments carry gold over thicknesses up to 3 m.

Dec 07, 2005 (K R Kettles) - MDI1 DATA: GRADE 1946 DDH ON KRL509638/1611 BDRY: MANY EN ECHELON INTERSECTIONS WITH MAX.WIDTH 3M, MAX.GRADE 0.18 OPT AU/1.37 M Diamond drilling on KRL 509638/1611 boundary obtained many auriferous en echelon, intersections with maximum width of 3 m and maximum grade of 0.18 oz/ton (6.171 g/tonne)Au over 1.37 m, according to the 4 drill logs available (Heath Gold Mines Limited, Bull Red Lake Gold Mines Limited, 1946?).
Dec 07, 2005 (K R Kettles) - Quartz lenses indicate silica in the chemical sediments has been remobilized causing local silicification. The chemical sediments are altered to epidote in places. The felsic tuffs may be silicified.
