Mobile underground diamond drill rigs offer significant advantages over the older style skid mounted configurations, which have a reputation for poor safety, low productivity, restricted drilling range and high total costs per Inetre. The key benefits of a mobile underground diamond rig are summarised as follows:

  • Reduced rig move times -average rig move time (level to level) of 2.5 hours versus skid mounted rigs of up to 36 hours, providing significantly greater drilling time each month.
  • Reduced hole set-up times- average hole to hole set up time (same cuddy) of one hour, leading to minimal non-productive time.
  • Increased metres drilled – 50°/o to 100°/o increase in metres drilled per month owing to the improved mobility and minimal non­ productive time.
  • Reduced safety hazards -major safety hazards engineered out, with no manual handling of major drilling components, reduced trip hazards, ergonomic design and self pinning ability.
  • Full drilling range- the boom configuration offers 360 degree drilling capability, including the ability to drill steep up-holes, rig power and set-up covers the entire drilling scope from grade control to deep exploration wire line.

Value Proposition

Mobile underground diamond drill rigs also offer a superior value proposition over the older style skid mounted configurations, summarised as follows:

  • Reduced rig move and hole set-up times equal greater drilling time, which in turn equals increased productivity.
  • Increase productivity enables the spread of fixed drilling costs over more metres, reducing the total cost per metre.
  • Increased productivity also reduces the amount of non-drilling charges such as standby, reducing the total cost per metre.
  • Increased productivity also reduces the number of rigs and therefore men on site by up to 50°/o, providing significant cost savings through reduced supervision, reduced flights and reduced accommodation and messing.
  • Less rigs on site reduces the requirement for, and therefore cost of, providing power, water and vent.
  • The mobile, fully integrated rig eliminates the need for clients to move components from site to site, reducing logistical support costs.

Safety Focus

AUD Directors pride themselves on being industry leaders in achieving injury free work sites through experienced operations crews, innovative drill rig designs, a comprehensive safety management system, high quality training systems and a strong safety culture.

AUD Directors have an excellent safety record. As a management group they were in control of a division that recorded no LTI’s over the last 12 months. Their division had achieved +1,000 LTl free days and no LTl days since start-up in October 2010.


AUD’s service philosophy is to deliver lower overall costs per metre drilling through the provision of experienced drilling personnel and best practice equipment, supported by high quality safety, maintenance and asset management systems.

AUD Directors have a strong service history in the provision of underground diamond drilling services, having been pioneers in achieving widespread commercial acceptance of a mobile drill rig in the Australian market. AUD can provide the experienced operations team with the advantage of a strong understanding of ground conditions.

AUD is extremely confident that it can provide industry leading productive, safe and valuable drilling services. The “Second Generation” AUD Mobile Diamond Drill has become the new bench1nark for productivity, safety and versatility. When combined with the experienced operations team and extremely competitive pricing, AUD believes it will provide a highly competitive total cost per metre supported by the significant ancillary cost benefits delivered by the AUD Mobile Diamond Drill.
