Metres Down Under Pty Ltd (MDU) is a privately-owned drilling company based in Kalgoorlie-Boulder, Western Australia, and specializes in the use of In-The-Hole-Hammer (ITH) technology for underground applications.

We have the capability of drilling holes from 90mm up to 760mm in diameter and are able to provide professional advice on any mining project where ITH drilling is utilized.

Our modern Cubex Drill Rigs are equipped with the Machines Roger V30 raise drill and we now have the added capability of drilling 760mm diameter raise holes for cut off slots, emergency escapeways, vent shafts and service holes. The ability to drill a raise hole and blastholes with the same drill rig is a very cost effective method for excavating long ventilation shafts and stopes.

MDU is the only contracting company in Australia with the V30 raise capability and we have also developed other drilling methods such as linear slot drilling for short rises and underground reverse circulation systems for exploration and infill drilling.

Metres Down Under Pty Ltd is committed to using ITH technology to increase safety and productivity in underground mining and has invested in the most modern ITH drill rigs and equipment available to achieve this.

Our range of drilling services include:

          - V30 Raise Drilling
          - Linear Slot Drilling
          - Longhole Rising
          - Stoping Blastholes
          - Service Holes
          - Reverse Circulation Drilling

ITH drilling technology has advanced considerably and is a cost effective way of drilling medium to large diameter holes safely, efficiently and far more accurately than other methods. Accurate drilling means less redrills and lower dilution, which can reduce overall mining costs and increase profits.
