Hammerstone Corporation is developing the industrial mineral potential of its extensive mineral properties in the Athabasca oil sands region, in northeastern Alberta. Hammerstone Corporation is the owner and operator of a limestone quarry located in the heart of the mineable oil sands area of Athabasca, 60 km north of Fort McMurray.

In the Athabasca region, there is a looming shortage of aggregate for road construction and regional infrastructure development. Hammerstone quarry provides a significant, local, secure, year-round source of limestone aggregates and environmental materials that will help enhance the sustainability and environmental performance of the oil sands industry.
