Frequently Asked Questions
What is exploration drilling used for?
Exploration drilling is used to investigate subsurface conditions before construction, mining or environmental projects begin. It helps identify mineral deposits, groundwater levels, soil types or contamination, providing vital data for feasibility studies, design planning or regulatory compliance in industries like mining, agriculture, infrastructure and environmental management.
What are the types of exploration drilling?
Common types include rotary drilling, diamond core drilling, and reverse circulation (RC) drilling. Each method is suited to different conditions and project goals—rotary for quick boreholes, diamond core for precise sampling, and RC for efficient mineral exploration with minimal contamination of collected samples.
How deep can exploration drilling go?
Exploration drilling depths vary based on project requirements and geology. Shallow environmental or groundwater bores may be less than 50 metres, while mineral exploration can extend several hundred metres deep. The method, equipment and ground conditions all influence how deep a borehole can be drilled safely and effectively.
