Location Method: Data Compilation
1925: the property was owned by the Red Lake Prospector's Syndicate, and was optioned by Dome Mines, who carried out trenching and limited sampling. 1937-38: 14 claims were staked by W.C. and J.E. Durham, who did some X-ray drilling. 1945: Durham Red Lake Gold Mines Limited was incorporated to take over the property, and geological mapping and 4605.2 m of diamond drilling was carried out. 1946: prospecting trenching and 4605.2 m of diamond drilling. 1947: 4193.45 m of diamond drilling. 1959: the company name was changed to Durham Explorations Limited. An agreement was made by which Dickenson Mines Limited was to take control of the 14 claims and contribute a further 10 claims to the property. Parvus Mines Limited was incorporated in 1960 to take over the combined group of 24 claims. 1962: unrecorded amount of diamond drilling. 1971: geophysical surveys. 1972: six diamond drill holes totalling 872.3 m. 1973: one short drill hole and geophysical survey.

Dec 07, 2005 (A Mitchell) - The property is located Southwest of the Dome Stock. The principal rock types underlying the property are, mafic metavolcanic flows and mafic to ultramafic intrusions. Locally, the metavolcanic flows are highly carbonatized, silicified and deformed, an in the past have been described as felsic to intermediate flows and pyroclastic rocks. The mafic to ultramafic intrusions are sill-like bodies of gabbro and serpentinite. A small body of quartz porphyry outcrops in the eastern par of the property. DEPOSIT DESCRIPTION: The No. 4 quartz vein has been delineated by drilling for a total strike length of about 150 m. The vein has an average width of 2-4 m. The vein contains appreciable amounts of sulphides but only low average gold values. Visible gold has been reported from one drill hole. GEOPHYSICAL DATA: The ultramafic intrusives are indicated by a high magnetic profile. Several VLF-Em conductors have been recognised and these represent either iron formation units (strong conductors) or shear zones (weak conductors).
