The Louise showing is located on the west side of Bear River, 5.0 kilometres north-northeast of Stewart.
The showing comprises tungsten mineralization hosted in calcsilicate beds in a sequence of tuffs and clastics of the Lower Jurassic Unuk River Formation (Hazelton Group). These have been contact metamorphosed to mica schists. These beds lie about 150 metres north of a large body of granite of the Eocene Hyder pluton (Coast Plutonic Complex), strike north and dip 25 to 40 degrees west.
Tungsten mineralization is contained in a 0.6 to 1.8 metre wide calcsilicate bed, traced for 46 metres, and in a series of calcsilicate lenses up to 0.6 metre wide and 1.0 metre in length. These contain scheelite in a gangue of calcium silicates and minor calcite. Grab samples of higher grade material from the lenses have assayed 0.04 per cent and 0.27 per cent tungstic oxide (WO3) (Bulletin 10, page 54).
