Lanigan Mine
Owner: PotashCorp

PotashCorp owns and operates an underground potash mine at Lanigan, Saskatchewan. Production of potash from Lanigan mine began in 1968.
The mine site is located just off Highway 16 near the town of Guernsey, 100 kilometers (60 miles) east of Saskatoon, province of Saskatchewan, Canada. The Lanigan Potash Mining Lease Area encompasses approximately 52,025 hectares (128,557 acres).
Potash produced at Lanigan is standard and granular used in the fertilizer and agricultural industry. It is shipped via Canadian Pacific and Canadian National railways to centers throughout North America or to ports for delivery offshore.
Geology & Mineralization
The sylvite (potash) deposits of Saskatchewan formed over 350 million years ago as a result of the final stage of evaporative concentration of sea water in a middle Devonian sea.
The productive Praire Evaporite Formation comprises a series of flat-lying sedimentary deposits of interbedded sylvite (KCl), carnallite, halite beds and clay and dolomite beds.
Stratigraphy of the region is dominated by three important potash bearing beds: the upper Patience Lake member (exploited by mines employing underground and solution mining methods); the middle Belle Plaine member (solution mining); and the lower Esterhazy member (underground and solution mining).
Virtually all Lanigan underground mining rooms are in one of two potash mineralized zones situated approx 15-30 m below the top of the host evaporite salt, the Prairie Evaporite Formation. Depth to the top of the main mineralized zones varies between 980 m and 1050 m, averaging approx 1000 m over most of the mining and exploration area.
Mining works are protected from aquifers in overlying formations by salt and potash beds, and salt plugged porosity in the overlying Dawson Bay Formation, a carbonate lying immediately above potash hosting salt beds.
