Mineral Exploration Drilling
Our advanced mineral exploration drilling services support your discovery and evaluation efforts. With specialised equipment and expertise, we ensure precise data collection for resource assessments.
Wireline Coring (BQ – PQ)
Collection of rock samples using a wireline retrieval system for geological analysis and resource estimation.
Conventional Coring (NMLC, HMLC, and 4C)
Retrieval of rock samples using various conventional coring methods for geological and geotechnical assessment.
Mud Rotary & Air Rotary
Drilling techniques using drilling fluid or air to circulate cuttings and cool the drill bit, suitable for various ground conditions.
DTH (Down-the-Hole) Hammer Drilling
High-impact drilling method using a pneumatic hammer at the bit face, ideal for hard rock formations.
Mining Geotechnical Investigation
We provide expert geotechnical drilling services to support the safe and efficient execution of mining projects. Our team specialises in site investigation to gather critical data that informs project planning and development.
Geotechnical Drilling Services
Our geotechnical drilling services include sampling and testing to evaluate soil and rock stability, foundation suitability, and other essential geotechnical factors.
Geotechnical Reporting
We generate detailed geotechnical reports that summarise investigation results, offering valuable insights and recommendations to support your project’s engineering and safety requirements.
Auger Sampling
Collection of soil samples using an auger drill for soil classification and contamination assessment.
SPT (Standard Penetration Testing)
Determination of soil properties and bearing capacity through driving a standard sampler into the ground.
CPT (Cone Penetration Testing)
Continuous measurement of soil resistance and other parameters using a cone-shaped probe.
Undisturbed Sampling (u50 – u100)
Collection of high-quality soil samples with minimal disturbance for accurate laboratory testing.
In-situ Testing (Packer Testing)
Measurement of hydraulic conductivity and other soil parameters directly in the ground using inflatable packers.
