1930s: Ground was originally staked by persons unknown (Fisher?). Limited prospecting and development. 1969: Ground was optioned to Madsen Red Lake Gold Mines Limited and Silvermaque Mining Limited by C. Fuller Pine of Balmertown who had staked the property earlier. 1970: Trenching, prospecting, EM and magnetometer surveys. 1971: One diamond drill hole completed.

Dec 07, 2005 (K R Kettles) - GEOLOGICAL DESCRIPTION: The occurence is located on the west boundry of the Dome Stock and is primarily underlain by augite diorite. To the northwest occur units of chemical metasediments (marble), clastic metasediments (greywackes to arkoses) and intermediate metavolcanics. Iron formation units are interlayered with the clastic sedimentary rocks. Metasedimentary and metavolcanic rocks are intruded by granitic dikes. From geophysical interpretation, the strike of the metasediments and metavolcanics appears to be NE-SW. This direction parallels the contact between the Dome Stock and other units to the northwest. DEPOSIT DESCRIPTION: Little information has been recorded about this occurence, other than the fact that gold seems to be located in units of chemical metasediment (marble). These units contain narrow beds of chert, which may be auriferous, and short sections where magnetite is disseminated. GEOPHYSICAL DESCRIPTION: A strong EM anomaly with an associated magnetic high was delineated northwest of the island. The anomaly is approximately 1300 m long, strikes NE-SW and is open ended to the northeast.

Dec 07, 2005 (K R Kettles) - Several sections from drill core returned assays of up to 0.07 oz/ton (2.400 g/tonne) Au over 1 m intervals.
Dec 07, 2005 (K R Kettles) - Minor epidote is located in quartz diorite intrusions. Greywackes have been silicified to cherty greywackes. Carbonatization along fracture planes has been observed.
