Mineral Exploration

Drilling technologies and methods

O’Keefe Drilling has provided the western United States with deep mineral exploration and production drilling for nearly 35 years. These services are used primarily by major gold and copper producers drilling down to remove ore samples for geological assessment.

O’Keefe Drilling offers a complete range of mineral exploration drilling technologies and methods – reverse circulation, rotary, grade control drilling, including Percussion Hammer System, borehole directional surveys (gyroscopic and magnetic) and spot core services – to meet the challenges of difficult subsurface conditions at exploration sites.

Our specialty is Reverse Circulation Drilling with both truck and buggy rigs. We own and operate five of these drills. They are equipped with the latest sample splitting technologies. Our rigs have been adapted to our specifications to ensure the highest quality sample and lowest hole cost in the industry.
