Air Core Drilling
Wallis Air Core drilling provides rapid, uncontaminated mineral samples using compressed air and hollow drill bits. Our compact rigs access difficult terrain with minimal environmental disruption while maintaining lower operational costs. The technology, invented by Wallis in 1974, remains the industry benchmark for exploration efficiency.
Reverse Circulation Drilling
Our reverse circulation drilling delivers fast, cost-effective rock samples for early-phase exploration projects. Using large rotary drills and air compressors, this method achieves high penetration rates while maintaining sample integrity through dual-wall drill rods and specialized cyclone systems.
Diamond Core Drilling
Diamond core drilling produces intact solid core samples for detailed geological analysis. Our advanced systems enable deep drilling with precise mineral deposit assessment capabilities, featuring rod spinners, dual breakout systems, and fire suppression safety features on MAN 8x8 carriers.
Grade Control Drilling
Grade control drilling uses reverse circulation techniques at shallow depths with close drill patterns to accurately map ore reserves. Our automated systems with wireless remote operation ensure precise data collection for mine planning and resource estimation.
Blast Hole Drilling
Our blast hole drilling services create precision holes for controlled mining explosions. Using high-pressure compressors and track-mounted rigs, we deliver efficient hole navigation systems that optimize fragmentation while maintaining safety standards for surface mining operations.
