1944: The property was held by MacBuck Red Lake Gold Mines Ltd. 1976: The property was held by Cochenour Willians Gold Mines. EXPLORATION AND DEVELOPMENT: Trenching and drillling on the MacBuck property were done from December 1944 to July 1945, and the surveying and geological mapping was started in September 1945 and completed by December of that year. In 1976, Cochenour Willians Gold Mines completed magneometer or VLF-EM surveys, and three holes were drilled in 1978 totalling 416.5 m. 0.06 opt Au/0.18m, 0.15 opt Au/0.49m, 0.17 opt Au/0.58m.

Metamorphism Type: Regional
Metamorphism Grade: Amphibolite
Dec 07, 2005 (K R Kettles) - GEOLOGICAL DESCRIPTION: The occurrence is underlain by a thick sequence of mafic metavolcanic flows. Massive, pillowed flow units have been observed. A strong foliation is developed in some of the units. It strikes NE-SW and dips at approximately 60deg. to the south. Thin interflow units of iron formation are inferred to be present, on the basis of geophysical data. DEPOSIT DESCRIPTION: Gold mineralization is reported to occur in quartz stringers in sheared mafic flows.
