1945: Red Pointe Gold Mines Ltd. was incorporated. Early development work consisted of surface work, and over 3350 m of diamond drilling in 23 holes. In 1970, C.W. Petersen had acquired the northern part of the property, and in 1973 Dickenson Mines held the southern part. 1970: C.W. Petersen drilled 450.8 m in 5 holes. 1973: Dickenson Mines flew an airborne magnetometer survey followed by ground geophysical surveys. 1974: Petersen completed stripping and trenching and 744 m of drilling in 10 holes. 1978: Petersen performed further stripping and trenching. 1982: Eldorado Nuclear, having acquired the southern half of the property, completed a geological survey on their property, followed up by 720.5 m of drilling in 5 holes during 1983.

Dec 07, 2005 (K R Kettles) - The property is underlain mainly by mafic volcanic flows with a few thin intercalated units of interlayered sulphide rich iron formation, greywacke, and argillite beds. Rock units strike northwest-southeast and dip to the south. Stratigraphic tops are to the south. The mafic metavolcanics are locally highly altered and deformed. Mineralization occurs in zones of altered volcanics.

Dec 07, 2005 (K R Kettles) - Anomalous gold values occur in narrow zones of altered mafic metavolcanics that are biotite rich. Up to 1% sulphides (pyrrhotite and chalcopyrite) are associated with gold values. Airborne magnetics have delineated several thin parallel sulphide iron formation units. Assays of core from the 1983 drill program by Eldor Resources yielded only low gold values. Hole GR-83-2: at 117 to 120 m assayed 310 ppb Au.
Dec 07, 2005 (K R Kettles) - The mafic metavolcanics have been silicified and carbonatized, and sections are locally biotitic, chloritic, and garnetiferous. The volcanics are depleted in Na20; enriched in Si02, K20, and C02.
