DIAMOND DRILLING SERVICES

We offer a comprehensive range of diamond drilling services for the mineral exploration, development, and mining industries. From surface programs to deep underground holes, every project is run by experienced supervisors on clean-tech equipment built for productivity and reduced environmental impact.

Underground Drilling

Providing safe, efficient underground diamond drilling for mining and development projects — including definition, delineation, and geotechnical holes. Our crews are highly trained and equipped to perform in confined, high-standard environments that underground operations demand.

Heli-Portable Drilling

Our heli-portable rigs access remote and roadless locations for exploration and geotechnical testing. Modular, transportable components let us reach sites where conventional access is impossible — without building costly infrastructure.

Deep Drilling

We complete deep drilling programs for exploration, development, and mining projects that require reaching significant depth. Experienced field crews and high-capacity rigs maintain hole quality and core recovery at depth, to depths beyond 3,000 metres.

Surface Drilling

Our clean-tech surface drills deliver safe, productive, and efficient core drilling for exploration and development programs. Built for performance in remote, challenging terrain, they advance holes quickly while keeping site disturbance low.
