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 banded iron formation.

Dec 07, 2005 (K R Kettles) - The banded quartz-magnetite iron formation contains approximately 20% magnetite, 60% silicate minerals, and 20% sulphides.

Dec 07, 2005 (K R Kettles) - Anomalous gold values occur in a unit of banded quartz-magnetite iron formation, containing approximately 20% magnetite, 60% silicates, and 20% sulphides. The auriferous zones are quite narrow, and generally contain less than 250 ppb Au over 2.0 metres. Airborne magnetics has delineated several thin, parallel, sulphide iron formation units. Only low gold values have been reported from the property. Drilling from 1983 returned the following results: DDH #GR-83-3: from 31.2 to 33.2 m - 210 ppb Au; from 38.0 to 40.0 m - 240 ppb Au; from 44.0 to 46.0 m - 110 ppb Au.
Dec 07, 2005 (K R Kettles) - The metavolcanics have been silicified and carbonatized, and contain appreciable amounts of biotite. Garnets are locally abundant in both the metavolcanics, and the iron formation.
