Reverse circulation drilling delivers a highly efficient and cost-effective solution for bulk sampling in exploration and pre-drill programs, combining speed, accuracy and reliability. Our modern fleet achieves consistently fast penetration rates while maintaining strict quality control to ensure sample integrity. This method is particularly effective for early-stage resource assessment, enabling large volumes of material to be processed quickly and providing geologists with accurate, representative samples for analysis.
By reducing contamination risks and delivering dependable results, RC drilling supports informed decision-making for project feasibility, resource modelling and planning. Its ability to operate effectively in a wide range of geological conditions minimises downtime and enhances productivity, making it an ideal choice for clients seeking timely, reliable data while controlling operational costs.
CDHD uses downhole hammering to improve drilling speed and efficiency in hard rock and consolidated formations. This technique uses high-frequency percussion to break through resistant ground while maintaining hole integrity and sample recovery.
By reducing time spent on bit wear and penetration, we increase productivity and minimise operational delays. Our teams apply this method across early-stage exploration programs and remote sites where dependable performance and consistent hole advancement are essential for meeting sampling objectives on tight project schedules.
We deliver reliable sample collection and bagging systems that ensure representative, contamination-free returns for accurate analysis.
Our field teams use cyclone systems and best-practice splitting techniques to preserve sample integrity from the moment it leaves the ground. Bagging is completed to strict quality control standards to support dependable laboratory processing and interpretation. This service is essential for early exploration phases where decisions rely heavily on the quality of recovered material and where clean sample handling can directly affect project outcomes.
Reverse circulation drilling is a cost-efficient method for bulk sampling in early-stage exploration and evaluation programs.
CDHD helps clients reduce project expenditure by maintaining fast penetration rates and minimising idle time across site operations. By using robust systems that deliver dry samples with minimal processing downtime, we lower the cost per metre without compromising quality. This approach is particularly beneficial in remote and large-area projects where budget certainty is important and operational efficiency is key to program success.
Our reverse circulation drilling capability is ideal for pre-drill programs where early geological insights are critical to project planning and feasibility.
We deliver rapid, reliable sampling results that help define target zones and support follow-up exploration. CDHD’s experienced crews and mobile rigs enable quick deployment in greenfield or remote settings, ensuring sample recovery starts without delay. With a focus on safety, quality and consistent delivery, our RC service supports data-driven decision-making from the first stage of every project.
