​15-Mile Processing Hub Project

Project Description (Impact Assessment Agency of Canada)

15-Mile Minerals and Renewables Ltd. is proposing to construct, operate, decommission and reclaim three historic open-pit gold mines, located 85 to 145 kilometres northeast of Halifax, Nova Scotia. As proposed, the 15-Mile Processing Hub Project would consist of the 15-Mile Mine site (formerly the Fifteen Mile Stream Gold Project), Old Austen Mine site (formerly the Beaver Dam Mine Project) and Old Mitchell Mine site (formerly the Cochrane Hill Gold Project). The 15-Mile Mine site would include four open pits, infrastructure to manage water, tailings and other mine waste, and an ore processing plant. The Old Austen Mine and Old Mitchell Mine sites would each include a single open pit, mine waste storage areas, water management, and infrastructure to transport mined material to the 15-Mile Mine site for processing. The project's total ore production and processing capacity would be approximately 8220 tonnes per day over a mine life of about 11 years (IAAC, 2026).

Current Stage: Planning 

​-Federal regulators are currently deciding whether this project should remain under federal environmental assessment or be left primarily to a provincial review process.
-The Impact Assessment Agency of Canada has provided a summary of issues related to the project.
