The exact location of the Superior showing is not known. It lies about 9 kilometres northeast of Stewart and approximately 3.1 kilometres east of the Stewart highway (37A).
The area is predominantly underlain by north striking, west dipping argillites of the Middle Jurassic Salmon River Formation (Hazelton Group) (Bulletin 58; 63). North trending dikes are conspicuous in the area. The showing may lie close to the southern contact of the Tertiary Bitter Creek quartz monzonite pluton.
Few details are available regarding the mineralization. Mineralization occurs in small shears on either side of a light coloured, fine-grained dike. The tunnel was emplaced along the footwall of the dike. High silver values have been reported. The dike may be related to the Bitter Creek pluton (Property File - KRL Resources Ltd., Statement of Material Facts, February, 1991).
In 1925, Superior Mines was formed and purchased the B.C., O.&H. 1-2 and Albert claims that lay immediately north of the Emperor Mines property (104A 056). No work was done on the postulated extension of the Emperor vein, but some opencuts and a 6 metre long tunnel were emplaced on a cross-vein at 1036 metres elevation. No further work has been reported on the showing. In 1980, Hopper staked the MM 100 claim over the area and carried out prospecting. Kingdom Resources Ltd. (later renamed KRL Resources Corp.) subsequently acquired the property. During 1981-83, Kingdom Resources carried out geological mapping, prospecting, trenching, sampling and soil and rock geochemical surveys in the area, mostly west of the occurrence. In 1990, KRL conducted prospecting, geological mapping, airborne and ground VLF-EM and magnetometer surveys. Most of this work was done along Victoria Creek, west of the prospect. During 2017 through 2020, Singer Resources Inc. and American Creek Resources Ltd. completed programs of geochemical sampling, a 13.5 line-kilometre induced polarization survey and a 438.5 line-kilometres airborne magnetic and LiDAR survey on the area as the Dunwell property.
