1945: Duluth Red Lake Gold Mines incorporated to develop the property. Early development work included surface trenching, stripping, geological and geophysical surveys and about 900 m of diamond drilling. 1956 to 1962: 5 holes drilled for a total of 613 m. In 1957 Dickenson Mines owned the property. 1969: Cochenour Willans Gold Mines performed geophysical surveys, and drilled 2 holes totalling 216 m. 1975: Dome Exploration Canada performed ground magnetometer and electromagnetic surveys, and drilled 6 holes totalling 1102.27 m.

Dec 07, 2005 (K R Kettles) - The occurrence is situated in an east west striking band of altered mafic volcanics which is underlain to the north and overlain to the south by sequences of intercalated clastic and chemical sedimentary rocks. Rock units dip 50 to 60 degs south.

Dec 07, 2005 (K R Kettles) - Occurrence is in an E-W band of basalts which are silicified, carbonatized and are garnitierous and biotite-rich. They are overlain and underlain with sequences of intercalated clastic and chemical sedimentary rocks.

Dec 07, 2005 (K R Kettles) - Anomalous gold values occur in highly silicified units of basalt with up to 25% quartz occurring as thin stringers. Two drill holes #75-1 and #75-2 intersected narrow zones of mineralization. Hole #75-1: 0.40 dwt/ton Au from 116.91 to 117.21 m. Hole #75-2: 0.40 dwt/ton Au from 143.05 to 143.23 m. The intersections were probably from different zones.
Dec 07, 2005 (K R Kettles) - The basalts have been silicified, carbonatized, depleted in Na2O, and are garnitiferous. The altered basalts have been described as being brown in color suggesting they also contain appreciable biotite. They have also undergone enrichment in CO2, SiO2, and K2O.
