The property was first staked in 1936 by T. Christianson and E. Frederickson, who performed surface exploration work. In 1938, the ground was optioned by J. E. Hammel, who drilled 19 DDH totalling 610 m. By 1952, the property had been re-staked by A. Larson and in 1954 was probably held by J. Hurnous. Between 1954 and 1964 at least 10 trenches and 44 drill holes totalling 1645.78 m were completed. In 1980 the property was optioned to Sherrit Gordon Mines Ltd. by E. Gay of Red Lake, 23 trenches were cleaned out, and an extensive sampling program of these trenches was carried out. 1987-88: Black Cliff mines carried out line cutting, geological mapping, sampling, magnetometer, VLF-EM and IP surveys. 1989: Cypress Gold Canada Ltd. optioned the property from Black Cliff Mines Ltd. and drilled 19 DDH totalling 3091.6 m, including 4 DDH totalling 634.5 m on and near this showing. 2010: Prospecting program was carried out on behalf of Larry Herbert. Grab samples taken.

Metamorphism Type: Regional
Metamorphism Grade: Amphibolite
Dec 07, 2005 (K R Kettles) - GEOLOGICAL DESCRIPTION: The property is located approximately 1 km south of the Killala-Baird Batholith. It is underlain by a zone of sheared and altered mafic metavolcanics and iron formation. This zone extends along the south shore of Laird Lake and strikes approximately N70 deg. E. Rocks in the zone dip 80 deg. S. Both the metavolcanics and iron formation are highly sheared. These shear zones are heavily mineralized with pyrite and chalcopyrite. Some shear zones have been reported to contain quartz veins with widths up to 10 cm. In the sheared iron formation, magnetite has been replaced by hematite and limonite. Trenching has exposed the quartz veins and pyrite and chalcopyrite seem to occur along the borders of the vein. DEPOSIT DESCRIPTION: The showing is located in a unit of relatively massive mafic metavolcanics containing thin quartz stringers, disseminated pyrite and local pyrite stringers.
