Gypsum & anhydrite

POTENTIAL & KNOWN RESERVES IN ALBERTA

Peace Point (protected); Grande Cache 2.6 Mt @ 75–80 %; Kananaskis deposit

Confidence: Inferred

• Grande Cache2.6 Mt @ 75–80 % gypsum (1972)AGS gypsum ↗
• Peace PointBeds 10–50 ft, inside Wood Buffalo National ParkAGS gypsum ↗

Where it occurs

• Peace Point
• Grande Cache
• Kananaskis / Bow River Forest Reserve
• Head Creek
• Clearwater River subsurface (84 %)

GEOLOGY: WHAT MAKES A DEPOSIT MORE LIKELY

Marine evaporite gypsum / anhydrite at or near surface where Devonian evaporites outcrop.

Host formations

Prairie Evaporite / Chinchaga · Devonian evaporites of the Front Ranges

Depth range

0–50 m

Favourable conditions

• Hydrated (gypsum, not anhydrite) beds over 5 m
• Outside parks and forest reserves
• Within trucking distance of a wallboard plant
