Diamond Coring and Drilling Services

MINERAL EXPLORATION AND GEOTECHNICAL INVESTIGATIONS

Diamond core drilling systems enable collection of high-quality samples with near 100% recovery for the assessment of mineral deposits and geotechnical investigations in construction sites, dams, bridges and everything in between.

Diamond core drilling uses a heavy duty diamond bit, attached to the end of the drill rod. The opening at the end of the diamond bit allows the collection of high-quality cores. The diamond encrusted drill bit is specifically suited for drilling in competent and hard rock formations.

Legion carries a broad range of diamond drilling equipment, including track-mounted, multi-purpose compact machines able to perform conventional (NMLC) and wireline coring (NQ3, HQ3, PQ3) to a maximum depth of 2,000 m below ground level.

We have depots across the East Coast in Brisbane, Townsville and Sydney and have completed numerous drilling programs in Northern Territory, South Australia and Western Australia.
