Diamond Core Drilling Rigs – Underground Operations

Compact, powerful and purpose-built for underground environments, our diamond core drilling rigs deliver precision core recovery in active mine headings, drives and stopes.

Boart Longyear - LM 110

The Boart Longyear LM 110 is a high-performance underground diamond coring rig engineered for deep-hole exploration in demanding mine environments. Its powerful 110 kW hydraulic system delivers high torque, strong pullback capacity and reliable rod-handling performance, supporting productive and consistent drilling operations at depth.

Boart Longyear - LM PQ

The Boart Longyear LM PQ configuration extends the proven LM platform to PQ-size diamond coring. In addition to its surface capabilities, the rig can be configured for reliable underground drilling operations where larger-diameter core recovery is required.
