For the past decade Canadian Wollastonite has been preparing to extract the industrial mineral wollastonite, and other ancillary minerals, from a significant deposit called the Saint Lawrence Wollastonite Deposit (SLWD) located in the north east district of the City of Kingston, Ontario and partly in the Township of Leeds and the Thousand Islands. On December 10 2012, CW received final approval for its mine closure plan from the Ontario Ministry of Northern Development and Mines, having received all requisite federal and provincial environmental and operating approvals. In doing so CW became the first industrial mineral mine to be approved in Southern Ontario in 35 years. The SLWD contains +30M metric tonnes of economic minerals, proven by drilling and other exploration and development activities. The Province of Ontario has designated the SLWD as a “Provincially Significant” mineral resource, and the official plans of both municipalities in which the SLWD is located recognize and protect the deposit for mining and mineral extraction. CW is the only wollastonite mine in Canada and one of just three in North America.
