Casa Berardi mine has both open pit and underground infrastructure, as well as a mill. Hecla plans to develop three additional open pits (Principal, WMCP, and F134) and associated waste rock storage facilities, and other surface infrastructure for future mine operations.
As part of the Casa Berardi mine transition from an underground/open pit operation to an open pit only operation, the lower margin East mine underground operations were closed in July 2023 and only the better margin stopes of the West underground mine will be mined until mid-2024, at which time most underground activity will stop except for exploration. |
