St. Marys Cement Bowmanville Underground Expansion Project (Issuance of mining lease)


2018 Update:

CBM/SMC has made the decision to not move forward with the program after reviewing the results of further rock quality testing, specifically completed for the purpose of determining the suitability of using this aggregate in high-strength concrete. As a result the project has been put on indefinite hold by CBM/SMC at this time. Subsequently the Ministry of Energy, Northern Development and Mines will not be processing the application for a mining lease and the associated Category C Class Environmental Assessment will be discontinued. Should future evaluation of the rock quality support a reapplication to the ministry, it will be assessed as a new undertaking under the Ministry’s Class Environmental Assessment.

The project is located in the Municipality of Clarington, approximately 20km south of the City of Bownmanville, southern Ontario.
