The Kicking Horse and Monarch carbonate hosted Zn-Pb-Ag deposits are located in south-eastern British Columbia, Canada. They are hosted by a black dolostone unit of the middle Cambrian Cathedral Formation approximately 130 m above the base of the formation and in proximity to the contact of that 20 m thick black dolostone horizon and the overlying >200 m thick light grey massive to coarse white hydrothermal dolomite. The deposits are on the south-western margin of the cratonic Western Canada sedimentary basin in the Foreland Thrust Belt of the Rockies.
The several ore zones, which are up to 400 m long, 40 m wide and 6 m thick and plunge gently to the NNW, are localised in small amplitude anticlinal crests. The mineralisation is a coarsely crystalline white to dark grey sphalerite and galena disseminated in a sparry white dolomite which cements dolostone breccia clasts. Pyrite ranges from trace to dominant, while minor chalcopyrite has also been noted. The ore zones occur on either side of and are elongated normal to a deep valley and prior to erosion may have originally been much more continuous and larger.
Historic production between 1912 and 1952 amounted to 0.826 Mt @ 8.6% Zn, 5.6% Pb, 30.4 g/t Ag.
