For the mineral exploration industry in Western Australia, the initial stages of investigation are crucial. Identifying prospective ore bodies requires efficient and cost-effective drilling methods that can provide valuable geological data quickly. At Bostech Drilling, we’ve built our reputation on delivering precisely that, with air core drilling in Western Australia standing as one of the cornerstones of our service. This method offers a reliable, quick, and affordable solution for obtaining valuable insights into subsurface conditions, making it an ideal choice for early-stage exploration.
Since our inception in Western Australia, Bostech Drilling has become synonymous with reliable and high-quality drilling solutions for mineral explorers. We understand the unique challenges and demands of this industry, from the vast and often remote terrains to the critical need for accurate subsurface information. Air core drilling, with its speed and efficiency, plays a vital role in meeting these demands, allowing explorers to rapidly assess the potential of their tenements.
What Exactly is Air Core Drilling?
Air core drilling, also known as rotary air blast (RAB) drilling in some contexts, is a rapid and relatively inexpensive drilling technique primarily used for shallow exploration. It employs a drill bit with tungsten carbide buttons or blades that pulverise the rock and soil as it rotates. Compressed air is then injected down the drill string to eject the broken material – the drill cuttings – back to the surface via the annulus (the space between the drill rod and the borehole wall).
The beauty of air core drilling lies in its speed and efficiency, particularly in unconsolidated or weakly consolidated ground like sand, gravel, and weathered bedrock. This allows for rapid progress and the collection of a large number of samples over a relatively short period, making it ideal for initial reconnaissance and broad-scale exploration programs.
The Key Advantages of Air Core Drilling for Mineral Exploration:
⦁ Speed and Efficiency: Air core drilling boasts significantly faster penetration rates compared to other methods like diamond core drilling, especially in softer formations. This allows for quicker coverage of large areas, accelerating the exploration process.
⦁ Cost-Effectiveness: The operational costs associated with air core drilling are generally lower than those of more intensive methods. This makes it a highly economical choice for early-stage exploration when budgets can be tight and the need for extensive data across a large area is paramount.
⦁ Rapid Sample Collection: The continuous ejection of drill cuttings via compressed air provides a relatively quick and easy method for sample collection. Geologists can readily examine and log the material being brought to the surface, providing immediate insights into the subsurface geology.
⦁ Suitable for Shallow Exploration: Air core drilling excels in exploring the upper layers of the earth’s crust, typically down to depths of around 50-150 metres. This depth range is often sufficient for initial identification of mineralisation and geological mapping.
⦁ Minimal Environmental Impact: Compared to some other drilling techniques, air core drilling generally has a smaller environmental footprint, particularly in terms of water usage, as it primarily relies on compressed air for cuttings removal.
