Our Services

We offer a variety of drilling services to help you manage your projects. Quality and safety are our top priorities and go to great lengths to ensure all of our equipment and team members are performing at optimal capacity.

Reverse Circulation Drilling

Reverse Circulation (RC) Drilling

Our Reverse Circulation drilling services and exploration drilling services allow you to access hard to reach terrain and samples. Hammer design and dual wall drip pipe ensure that your samples are free from material interference and contamination.

Our contractors will calibrate our equipment based on your project’s depth, azimuth, and dip requirements.

Grade control services from Castle Drilling Company will save you time and money and will ensure your project stays as efficient as possible.


Mining & Civil

In addition to RC and Grade Control drilling, we have extensive experience providing mining and civil engineering and drilling services including blast hole drilling, Down the Hole Hammer (DTHH), and Fixed Cutter and Roller Cone drilling.

Our machines are maintained regularly so you get the best results for your project.
