Operating Challenges
Exploration sites are often remote, with drill programs moving frequently between many individual holes rather than staying in one location.
Hard, abrasive ground — common in mineral exploration — wears fluid-end components faster than softer formations.
Continuous circulation is essential to core recovery, so any interruption in flow can compromise sample quality, not just drilling progress.
Commodity price cycles drive sharp swings in exploration budgets and fleet utilization, making cost-efficiency a recurring priority. • Smaller-diameter boreholes and compact, portable rigs are the norm, which shapes pump sizing across the segment.
Why Pump Performance
Matters Here
In core drilling, the pump's job isn't just moving fluid — steady, uninterrupted circulation is what brings an intact, usable sample to the surface. Combined with exploration's tight budgets and frequent moves between holes, that puts a premium on compact, durable pumps and expendables built specifically for continuous duty in abrasive ground, rather than general-purpose components pressed into exploration service.
Frequently Asked Questions
What size mud pump is used for core drilling?
Mineral exploration and core drilling typically run on compact to mid-range triplex pumps in the 100–500 HP range, sized for the smaller-diameter boreholes and portable rigs common to the segment.
How long do expendables last in abrasive exploration ground?
Wear rates vary with ground hardness and utilization, but AMPX expendables are specifically optimized for continuous-duty core drilling in abrasive formations, which extends service life compared with general-purpose components.
How important is pump portability for exploration programs? Very — exploration programs move between many holes over the life of a project, so compact, easily mobilized pump packages reduce the time and cost of relocating between sites.
