Diamond core drilling (Exploration diamond drilling) utilizes an annular diamond-impregnated drill bit attached to the end of hollow drill rods to cut a cylindrical core of solid rock. Holes within the bit allow water to be delivered to the cutting face. This provides three essential functions; lubrication, cooling, and removal of drill cuttings from the hole.
Diamond drilling is much slower than reverse circulation (RC) drilling due to the hardness of the ground being drilled. Diamond rigs need to drill slowly to lengthen the life of drill bits and rods, which are very expensive.
Washingtons utilize a Hydril 1000 rig which can core down to 1000+ meters,KL1500 which can core down to 1800+ meters and purchased this year a HD 900 which can core down to 1100+ meters.
Our goal is to provide our clients with high-quality data on the geology of an area in an efficient and reliable manner
Diamond core drilling and surveys
We produce high quality information from underground in an efficient and trustworthy manner.

Our objective is to provide a reliable and first-rate service to the industry, making us leaders in drilling efficiency.
Our customers consist of various major exploration and mining companies, including L & M Coal seam and Gas, L & M Petroleum, Oceania Gold, Newmont Asia Pacific and other public-sector organizations.
Down hole surveys
By using inclination and deviation surveys using a Ranger multi shot camera, the location of the drill hole in 3D can be located extremely accurately. In addition to these surveys we also can supply a down hole camera for video footage.
One of the cornerstones of Washinton's success is the highly competent personnel with a strong sense of responsibility. Thanks to the modern drilling equipment and the high morale of the employees, our crew achieves excellent drilling results.
