Lithology Comments

Aug 02, 2017 (A Wilson) - Keewatin rocks cut by Haileyburian lamprophyre dikes are intruded by the Nipissing diabase sill. The upper contact of the diabase sill is circular with subhorizontal dip. Two faults cross the southwest portion of the claim; one strikes west- southwest and dips 70-80º NNE, the other strikes NNW and dips vertically. Silver-cobalt bearing veins mostly occur in the vicinity of the Keewatin-diabase contact. The silver and cobalt produced came mainly from veins nos. 1 and 2 which strike easterly and transect with steep dips both Keewatin rocks and Nipissing diabase. Base metal mineralization such as chalcopyrite and galena occurs in association with cobalt mineralization in veins No. 1 and No. 2.

Mineralization Comments

Aug 02, 2017 (A Wilson) - The average grade of silver between 1906 and 1911 was 81 oz./ton. The No. 1 Vein extends for a horizontal length of 600 ft. and persists to a vertical depth of at least 150’. Vein No. 2 extends for a horizontal length of 300’ and persists to a vertical depth of 250 ‘. Vein No. 10 has a horizontal length of 50’ and extends to a vertical depth of 75’. Production was restricted to where the vein cuts through the lamprophyre dike and andesitic lava.
