Access Description: The Six Mile Lake road branches off Hwy. 599 approximately 1 km south of the the Sturgeon River Rapids bridge. Approximately 4.6 km south of the intersection the Six Mile Lake road passes by the west end of Pointer Lake. The drill hole collar is located midway between the road and the northwest tip of Pointer Lake.
1983-84: Prospector K. Bernier examined a claim block on the Six Mile Lake road south of the Sturgeon River rapids. Several small trenches in the area around Pointer Lake gave low gold assays. These trenches followed a conductor discovered in a ground geophysical survey. 1985: Riverton Resources Corp. optioned a 3 claim block over the surface showings and drilled 5 holes on it totalling 1585 feet.

02/01/2000 (R Tuomi) - The property is underlain by pillowed mafic metavolcanic flows of the Six Mile Lake cycle, Robinson (1992). The mafics have narrow horizons of cherty tuff between flow units in several locations. Near Pointer Lake, bedding and foliation trend approximately east-west with moderate to vertical dip. Hole R-85-5 was drilled to 367 feet (112 m). A 5 foot interval at 327 feet assayed 0.139 ounce gold per ton in a 14 feet wide section with 1% to 2% sulphides. The 14 feet section was mapped as dacite.
