Point Location Description: Point 175m south and 170 m west of # 2 post claim KRL19642 on map P.1569A
Location Method: Conversion from MDI
The claim group was originally held by Marshall Red Lake Mines Ltd. and was staked sometime prior to 1946. 1946: Ground magnetometer survey. 1962: Three holes totalling 518.50 m were drilled on the Marshall Red Lake property. Dickenson Mines Ltd. (Goldquest Exploration) acquired the ground around 1981. 1981: Horizontal loop E.M. survey completed. 1982: Four holes were drilled totalling 479.16 m.

Dec 07, 2005 (K R Kettles) - GEOLOGICAL DESCRIPTION: The area is primarily underlain by massive and pillowed mafic metavolcanic rocks. Locally, these flows have been sheared, with the shear zones striking approximately N20deg.E. Southeast of the occurrence, iron formation units have been detected by geophysical methods. The shear zones in the area are mineralized with quartz and carbonate veins and minor sulphides, as well as being enriched in biotite. DEPOSIT DESCRIPTION: The occurrence is located in a mineralized shear zone within massive mafic volcanic rocks. The zone is characterized by moderate to strong shearing and weak brecciation with 5 to 10% quartz-calcite veining and minor pyrrhotite and pyrite. The zone has an estimated width of 1-3 m. GEOCHEMICAL DATA: The enrichment in biotite along the shear zones suggests potassic metasomatism.

Dec 07, 2005 (K R Kettles) - MDI1 DATA: GRADE 1982 DDH G-82-2: ONLY LOW GOLD VALUES, HIGHEST 0.07 OPT AU/0.6 M Only low gold values were returned from drill core assays, the highest being 0.07 oz/ton (2.400 g/tonne)Au over 0.6 m.
Dec 07, 2005 (K R Kettles) - The mafic metavolcanic rocks have locally been carbonatized and silicified, and contain abundant biotite and lesser amounts of chlorite.
