Reverse Circulation Drilling

ODM's founder, Stuart Averill, pioneered the modification and use of reverse circulation (“RC”) drills to sample glacial till in areas of deep overburden.

Surface Sampling

High-quality till and alluvial sediment samples are vital for an accurate geochemical sampling program. ODM designs and executes surface sampling surveys in areas of thin overburden cover in all regions of Canada. From the Cordillera of British Columbia, frost boils of the Arctic and in the forests and bogs of the Abitibi and Newfoundland, ODM has sampled it all.
