This well was drilled through a succession of evaporites, reefal carbonates and thin beds of clastic rocks of the Middle Devonian Elk Point Group. Two sulphur-bearing sections were intersected in the upper member of the Upper Keg River Formation. An interval at 2138.2 to 2141.5 metres depth contained a 1-metre section grading 30 per cent sulphur followed by a 9-metre interval of dolomite and anhydrite interbeds with a heavy sulphurous odour and possible native sulpur. A second interval at 2167.1 to 2173.2 metres depth comprised dolomite and possible thin sulphur-bearing beds. The native sulphur is yellow, coarsely crystalline to amorphous and burns out of the samples as sulphur dioxide. EMPR FIELDWORK *1988, pp. 529-531 EMPR PF (Hora, Z.D.
