Exploration History

1932: Russel Cryderman held the ground covering this showing and had excavated a number of pits along a quartz vein. Two zones were tested and the southern, or #1 vein, reportedly returned assays up to 6 g/t Au ($4/ton over 4'). 1950: Central Manitoba Mines carried out a detailed geological mapping program which covered the showing. The showing was resampled but with discouraging results as only 'low values' were obtained from samples containing arsenopyrite. A number of old additional trenches not shown on any map probably date from this program. 1979: Cominco remapped the area surrounding the showing while evaluating the banded iron formations to the south of the showing. In the following year a HL electromagnetic and magnetic survey were carried out and three targets on the iron formation were tested. 1980: Hargor Resources flew a regional magnetic and electromagnetic survey which covered this showing. 1990: Blue Falcon flew a regional magnetic and electromagnetic survey which covered this showing. . 2007-2008: Augen Gold Corp. - AEM, AMag, ARAD;.Assays, Pr.

Geology Comments

Dec 07, 2005 (S Fumerton) - The best mineralization is located at the intersection of an east - west sheared contact between conglomerates and arkoses and north trending diabase dykes. The surrounding conglomerates boulders are highly strained (50:1) depending on the lithologies.

Lithology

Lithology Comments

Dec 07, 2005 (S Fumerton) - The mineralization is hosted in a schistose conglomerate - arenaceous sequence. Within these schists there is a narrow (<30cm) massive unit, probably a quartz feldspar porphyry sill.

Mineralization

Mineralization Comments

Dec 07, 2005 (S Fumerton) - Mineralization occurs in a number of lenses hosted within a braided shear zone. Locally massive pyrite mineralization occurs as oblate ellipsoids 2 x 150 x 200mm parallel to the schistosity or as 5cm thick bands mixed with quartz. Elsewhere pyrite occurs as very fine disseminated grains or streaks in the schistose matrix. The disseminated sulphide mineralization also occurs in the porphyry. North of the main trenches a pop hole has been blasted on a quartz vein with disseminated sulphides and from which some gold values have been reported.

Dec 07, 2005 (A Wilson) - Assays reported by Cryderman in 1932 reportedly returned values up to 6 g/t Au. Grab samples collected by the OGS in 1980 returned values of 1.3 g/t Au. Grab samples collected by the OGS in 1994 returned values of 1.28 g/t Au, 0.4 g/t Ag; 0.07 g/t Au, 0.2 gt Ag; 9.56 g/t Au, 0.5 g/t Ag; 0.19 g/t Au, 0.2 g/t Ag.

Jun 12, 2013 (P Bousquet) - Assays from that area reported by Augen Gold Corp. have a highest result of 3.02 g/t Au (T-5852), coming from an altered sandstone.
