What we do
Diamond Core Drilling Services
Surface and underground diamond core drilling for mining exploration and geotechnical programs — anywhere in the country, any formation, any depth.
Mining Exploration Drilling
We drill the holes that define ore bodies. From early-stage grassroots exploration to resource expansion and infill programs, our crews deliver oriented, high-quality core that geologists can rely on.
Capabilities
- Surface and underground exploration programs
- HQ, NQ, and PQ core sizes to match your program design
- Deep-hole capability — NQ to 3,000 ft, HQ to 2,000 ft, PQ to 1,000 ft
- Oriented core drilling for structural geology
- Remote and high-altitude site mobilization
- Core handling, logging trays, and chain-of-custody support
Industries Served
- Gold & silver mining
- Copper & base metals
- Industrial minerals
- Coal & energy minerals
- Uranium exploration
Project Types
- Grassroots exploration
- Resource definition drilling
- Infill and step-out programs
- Underground mine development
- Feasibility-stage drilling
Geotechnical & Civil Drilling
Subsurface investigation for engineers and project owners. We provide the core and data your geotechnical team needs to design foundations, assess slope stability, and characterize site conditions.
Capabilities
- Geotechnical core drilling for site investigation
- Rock quality designation (RQD) and core recovery
- Standard penetration testing (SPT) support
- Piezometer and instrumentation installations
- Borehole logging and sampling
- Urban and restricted-access site capability
Industries Served
- Highway & bridge infrastructure
- Dam and reservoir projects
- Commercial & industrial development
- Slope stability assessment
- Environmental site investigation
Project Types
- Foundation investigation
- Slope stability borings
- Dam safety investigations
- Retaining wall design borings
- Environmental characterization
Why Contractors Choose Stone Brothers
Fast Mobilization
We move when you need us. Our rigs are ready to deploy nationwide with minimal lead time.
Deep-Hole Capability
Most programs don't push our limits. We've drilled past 2,400 ft and have the equipment to go deeper.
Difficult Access
Remote terrain, underground headings, urban sites — we've worked them all and know how to get the rig in.
Core Quality
High recovery rates and careful handling mean your geologist gets the sample they need, not a bag of chips.
