Our Project

Wynyard Potash Project

The Wynyard Potash Project is a Carnallite/Sylvinite solution mining project in central Saskatchewan. Using a modular approach, a 2.125 million tonnes per year plant will be constructed in 3 phases beginning with the 625,000 tpy Phase One. The project will produce a premium white granular potash product (KCl 97) with low sodium content. Karnalyte is taking a leading role in the potash industry on environmental stewardship with a potash mine having no salt tailings piles or tailings ponds. Karnalyte has completed a Bankable Feasibility Study, an updated Technical Report, a Preliminary Feasibility Study for magnesium compounds, and obtained EIS approval from the Saskatchewan Ministry of the Environment.

Size & Location

Karnalyte Resources Inc has 100% interest in KLSA 010, KL 247A, and KL 246 mineral leases comprising approximately 367 km2 (90,766 acres) of mineral rights. Karnalyte also owns around 4,100 acres of surface lands. The project is located approximately 190 km east of Saskatoon, SK, or 176 km north of Regina, SK. The plant site is located on primary Provincial Grid No. 640, just 2.5 km south of the town of Wynyard. Highway 16 (Yellowhead Highway, the northern route of the Trans-Canada Highway) and the northern main line of CP Rail run through Wynyard.

Mineral Reserves

The mineralized zone contains 3 potash bearing horizons located approximately 1000 meters beneath the surface. The Patience Lake Formation and Belle Plaine Formation are predominantly Carnallatite and are on average 9.4 and 15.3 meters thick respectively. The Esterhazy Formation is predominantly Sylvinite and averages 17.2 meters thick. Karnalyte’s mineral leases contain 147 million tonnes of KCl in the Proven and Probable categories, and 153 million tonnes of “minable” MgCl2 of which 7.9 million tonnes has been assigned as Probable Reserves.

Water Supply

Process Water for solution mining and disposal uses will be produced on site from the Blairmore Formation that is approximately 500 meters beneath the surface. Blairmore water is similar to seawater, with a slightly higher salt content. Karnalyte has drilled and tested 2 Blairmore water wells which have both produced in excess of 650 us gpm (2.5 m3/min).

Solution Mining

A proven solution mining process will be used, with directionally drilled dual well pairs ultimately joined at the bottom to form oblong caverns. The lower Esterhazy zone will be mined first, followed by the Belle Plaine and Patience Lake zones. Hot water will be injected to preferentially dissolve Carnallite leaving salt residues and insolubles underground. Large blocks of all the strata are left undisturbed between caverns as pillars to provide support for all overlying layers. When a cavern is mined out, salt tailings will be used as backfill to help minimize long-term subsidence.

Surface Facility

The surface facility removes water from the brine using evaporators, precipitating both salt and potash and separating them from the remaining magnesium chloride brine. The salt and potash are then separated in a conventional potash crystallizer circuit to produce 99% white potash. Both salt and magnesium brine are sent to disposal. The 99% potash is then sent to be pan-granulated into KCl 97 product.


Tailings from the surface facility are either used to backfill spent caverns or injected into deep disposal wells. The Deadwood and Winnipeg formations are approximately 1500 meters deep and are used by the potash industry for brine disposal. Karnalyte has drilled and tested one disposal well with flowrates observed up to 2350 us gpm (9 m3/min). Karnalyte’s Wynyard plant will be the first potash mine in Saskatchewan without a tailings pile or tailings ponds.

Magnesium Project Development

A Preliminary Feasibility Study has been completed for the production of 99% Hydromagnesite and 32% MgCl2 brine. A portion of the MgCl2 brine tailings from the potash facility would be utilized as feedstock to process into these products.
