INNOVATION . PERFORMANCE . SAFETY
At Bostech, we’ve developed a reputation as one of the leading industry exploration drilling contractiors. We’re committed to delivering high quality, cost effective drilling services, adhering to all relevant industry standards. Some of the key drilling services provided include air core drilling, RAB drilling, reverse circulation drilling and slimline reverse circulation drilling. Our rigs are capable of drilling a whole range of unconsolidated, sandy and heavy clay horizons that have proven difficult for other drilling techniques.
And when it comes to safety we make no compromises, having achieved and maintained Certification to AS/NZS 4801:2001 (Safety Management Systems) since 2016.

Air Core Drilling
Featuring unrivalled innovation and productivity, the Bostech Air Core system sets the benchmark in our industry and has been developed over many years to maximise productivity, reliability and the overall improvement of sample quality. Specializing in grade control, we pioneered the aircore kick-bit which is now used almost exclusively on all air core drilling rigs in Western Australia.
Today, we are still the front runner in the development and practice of aircore drilling with a fleet of rigs that maximise our commitment to Zero Impact Drilling. We avoid any noticeable or lasting side effects or damage to the immediate environment. We are dedicated to preserving Western Australia, and Australia.
Our air core system is extremely versatile, and can drill holes in ground from Paleo channel, sand and light clays through to sedimentary and basement clay. It can also penetrate hard bands to give small core samples in competent geology.
Hole sizes are generally 85mm-87mm in diameter, produced with rapid penetration rates, which makes it an extremely cost effective drilling method. Air core drilling is a much cheaper alternative when compared to RC drilling, which means more metres and ground can be covered, for less cost.
Our lightweight aircore rigs are highly manoeuvreable, have minimal impact on the environment and require much less surface preparation to allow the rig to access remote areas.
Rotary Air Blast Drilling
RAB Drilling is a traditional drilling method that is not as commonly used today, mainly because it’s less accurate than AirCore drilling - due to the use of a single tube.
As a result, samples have a greater chance of becoming contaminated, due to contact with the geology of the drill hole. This differs to air core drilling, where the sample is isolated from the geology by the sample tube.
As specialists in RAB drilling, we offer extensive experience and knowledge in this technique.
Slimline Reverse Circulation Drilling
Compact and powerful, our slimline reverse circulation rigs are easy to manoeuvre which makes them ideal for lower cost reverse cycle drilling in pits for grade control and sterilisation.
Combined with various face-sampling hammers, we have the capabilities to sample basement during an RAB/Aircore program, without the need to change equipment or mobilise extra crews.
