The public are reminded to continue to obey all posted signs across the Project area for everyone’s health and safety. Construction in and around Greenstone Mine involves the use of heavy equipment such as haul trucks, zoom booms, cranes, drills, excavators, skidders, bulldozers, tri-axle haul trucks, articulated trucks and loaders. The extensive project work over the last year has significantly changed the landscape resulting in many new hazards. For health and safety reasons, do not enter any unauthorized or active work areas within the Project footprint unless authorized to do so.

The safety of our employees, contractors and the general public is paramount as we construct the Greenstone Mine.
