Feb 09, 2011 (P Hinz) - The area is underlain by the High lake porphyritic granodiorite stock, which intrudes Archean mafic metavolcanic rocks. The stock has been interpreted to be two intrusive phases. (Davies 1965, Covline 1979). 'A thick sequence of massive to pillowed mafic flows is intruded by equigranular tonalite and granodiorite and by porphyritic granodiorite with feldspar phenocrysts up to 3 cm long (Figure 19). East- to northeast-striking faults and shears are common in the porphyritic granodiorite, and quartz is present in some of these.' (Davies and Smith, 1988)'. A thick sequence of massive to pillowed mafic flows is intruded by equigranular tonalite and granodiorite and by porphyritic granodiorite with feldspar phenocrysts up to 3 cm long. East- to northeast-striking faults and shears are common in the porphyritic granodiorite, and quartz is present in some of these. Reference: Davies, J.C. and Smith, P.M. 1988.

Feb 09, 2011 (P Hinz) - Three principal veins are known on the property (Davies 1965). Each occurs in sericitized, foliated granodiorite. Molybdenite and fine pyrite are present in quartz veins and also in the altered granodiorite. The No. l vein strikes about 100* and dips steeply north in its central position, and more shallowly to the east and west. The vein has been traced almost 700 m by drilling and is exposed in a trench near its centre. Trenches on the No. 2 vein are about 700 m southwest of the No. l vein trench. The No. 2 vein consists of several parallel, but apparently discontinuous, quartz veins, lenses and stringers which strike northeast. Its known length is over 200 m. Vein No. 3 crops out 100 m south of vein No. l and has a known length of about 200 m. It strikes southeast and dips 45 0 to 80 0 NE. Reference: Davies, J.C. and Smith, P.M. 1988.

Feb 09, 2011 (P Hinz) - Three principal veins are known on the property (Davies 1965). Each occurs in sericitized, foliated granodiorite. Molybdenite and fine pyrite are present in quartz veins and also in the altered granodiorite.' (Davies and Smith, 1988)'. Extensive drilling of No. l vein indicated the presence of 126,000 tons grading Q.68% MoS2 and 0.015 oz Au/ton over a length of about 365 m, a width of 1.4 m and a depth of about 155 m. The No. 2 vein included a 213 m length in which the average grade is about Q.47% MoS2 and 0.02 to 0.05 oz Au/ton. The No. 3 vein contains l to 20/*, MoS2, but the gold content is not known.

Aug 04, 2022 (Q Unknown) - Grade - #1 Vein: 126,000 tons @ 0.68% MoS2 + 0.015 opt Au; #2 Vein: 0.47% MoS2, 0.035 opt Au along 213 m; #3 Vein: 1.5% MoS2 Resource is 126,000 tons at 0.68% MoS2 and 0.15 opt Au. Indicated 200,000 tons of 0.63% MoS2. Inferred is 550,000 tons estimated to a depth of 254 m from OFR5695 p. 114
Dec 07, 2005 (P Hinz) - As indicated by Smith and Davies (1988), the mineralized quartz veins occur in sericitized and foliated granodiorite.
