Mining & Mine Services

Our roots are in mining, and that experience continues to shape the way we build today. We deliver the civil infrastructure that supports mine development, operations, and closure, from earthworks and water management to tailings facilities, roads, and site infrastructure.

MacKay was built at the Sullivan Mine, and four decades later mine sites are still where our standard is set: remote ground, heavy equipment, hard schedules, and zero room for surprises. Our drones map benches, stockpiles, and haul roads as the work moves, so owners see real progress against real volumes, not month-old estimates. We carry a mine-site discipline onto every project we build.
