Geological Age: Archean
Jan 29, 2020 (Therese Pettigrew) - The south Sturgeon Lake area is underlain by a well preserved, though partially eroded, Archean submarine volcanic caldera. This caldera is host to five massive sulphide deposits (Mattabi, F-Group, Sturgeon Lake Mine, Creek Zone and Lyon Lake) as well as numerous subeconomic massive sulphide occurrences. The Sturgeon Lake Mine, F-Group and Mattabi deposits were depleted of reserves in 1981, 1984 and 1988 respectively, whereas production at the Lyon Lake and Creek Zone deposits ceased in 1991 (Morton et al., 1996).
