Mineralogical investigation of some base metal ore deposits and occurrences in the Red Lake Mining Division, Ontario: M34-20/146E-PDF

“Three main types of base-metal sulphide mineralization are present in the Red Lake Mining Division: (1) Small massive copper-lead-zinc deposits occurring mainly in drag folds or shear zones in sequences of metavolcanic and metasedimentary rocks, sometimes intruded by gabbroic sills and invariably surrounded by granitic rocks. Most of these deposits are located in the belt of volcanic rocks in the Confederation Lake area, 50 miles east of Red Lake, and are typified by the Fredart Lake and South Bay Mines deposits. In the Red Lake area this type of deposit is represented by the Trout Bay sulphide prospect located on the western limb of the Red Lake basin-like volcanic complex. (2) Low-grade disseminated nickel and copper mineralization as shown by the Trout Bay nickel prospect. The mineralization occurs in an antigorite-tremolite schist occurring along the stratigraphic top of a chert-magnetite iron formation. The schist represents the sheared and altered basal portion of a metagabbro sill. (3) Massive to disseminated occurrences of galena in carbonate zones cut by numerous quartz stringers and veins. These shear zones are associated with metavolcanic rocks that have been intruded by quartz prophyry. The Galena Island and Middle Bay prospects are typical of this mode of mineralization"--Abstract, p. i..
