Central Manitoba Mine

 

This was Manitoba's first gold mine, starting production in 1927 to 1937. Eight separate deposits were mined, within a narrow belt about 2.8 km long. Five shafts were in use at various times, and over 16 km. of galleries were driven. A depth of 277m was reached late in the life of the mine, little ore was found deeper than 114m.

The deposits are located at or close to the contact between volcanic rocks and a mafic sill. A band of cherty tuff is host to several of the more productive veins. The veins occupy subparallel shear zones, and are flanked by quartz-chlorite-carbonate-pyrite alteration of the wall rocks. The ore minerals in the veins consists of pyrite, chacopyrite and some pyrrhotite. Gold is present partly as microscopic free gold and partly in the pyrite and chacopyrite. The ore contains 0.5% copper.
