Point Location Description: Drill set up on a little island in Opeepeesway Lake.
Location Method: Field Visit with GPS
Access Description: A boat is required to access the island from where most of the drilling was done.
Circa 1979: Trenching on the east shore exposed brecciated porphyry. 1964: Martin Burton carried out a diamond drill program from an island in Opeepeesway Lake. A total of nine holes were drilled over a four year period. 1984 Muscocho Exploration acquired the ground but all exploration was carried out over the Jerome peninsula and else where on the south shore. 2007: Augen Gold Corp. performed an aerial electromagnetic, aeromagnetic and aerial radiometric surveys (T-5671 / 2.37373). 2008: Augen Gold Corp performed prospecting and assays (T-5852 / 2.40516).

Dec 07, 2005 (S Fumerton) - The rock exposed on the island is a medium grained slightly flasered, porphyritic, feldspar, quartz granodiorite. The colour varies but generally a light pink - green. The green colour is due to chlorite which forms up to 20% of the rock. Hematite occurs as a filling along fractures in the granodiorite. Arkoses are also reported in the drill logs.
