Mine Contractor Since 2018
Full-service underground contracting
Consbec Mining + Tunneling delivers complete underground mine contracting — from initial portal and development work through to long-hole production, ground support and shotcrete.
On production work we focus on what the mill sees: less dilution, fewer fines and steady fragmentation, with ground control that keeps the headings advancing.

The Canadian Shield
We are Northerners
Most of our experience is in the complex Archean rock of the Canadian Shield, on surface and underground operations alike.
We plan a round around what happens after it: mucking, hauling and milling. Keeping the total cost down matters more than the cost of any one blast.
