The Beaver (Lussier South) quarry is located 1025 metres south of the presently producing Lussier quarry (082JSW009), on the east side of the Lussier River, 4 kilometres south of its confluence with Coyote Creek and 24 kilometres southeast from the village of Canal Flats. There has been some minor production from this quarry but no figures are available.

Refer to the Lussier deposit (082JSW009) for detailed regional geology on the Lussier River - Coyote Creek area.

Gypsum of the Devonian Burnais Formation is exposed along the quarry walls across a width of 80 metres. It is laminated to thin-bedded, pale grey to grey with some dark laminae present. At the south end of the outcrop numerous faults and some brecciated gypsum is present. Minor amounts of selenite, as blebs and stringers, occur throughout. Trace to minor amounts of native sulphur, dolomite, quartz, anhydrite were also observed. Trace amounts of albite, chlorite and syngenite, a hydrous, calcium- potassium sulphate salt, were identified by x-ray diffraction study (Open File 1991-15). A high salt content in the deposit caused cessation of production.
