A diamond core drilling company can mean a construction-tool supplier, a drilling contractor, or a manufacturer of mineral-exploration rigs. This guide focuses on the last category: companies offering equipment relevant to surface diamond core drilling, especially hydraulic rigs used to recover geological samples. If you are buying a core surface drill for a mineral program, the right shortlist depends less on a brand's reputation than on hole design, site access, safety and support.
These ten companies are presented as a procurement shortlist, not a sales-volume or performance ranking. CORTECH is the publisher's brand and appears alongside other suppliers; that relationship should be clear to readers. Product descriptions reflect publicly available information, not independent machine tests. Ask each manufacturer to confirm its current specifications and service arrangements before ordering.
A surface rig recovers rock core for geological examination. With wireline coring, crews retrieve the inner tube through the drill string while the rods stay in the hole. A concrete drill cuts openings in built structures; an RC rig produces a different sample. Specify the required method before comparing machines.
Manufacturers supply rigs; contractors execute drilling programs. This guide evaluates equipment suppliers, not contractor performance.
| Company | Relevant offering | Buying priority to investigate |
|---|---|---|
| CORTECH | Full-hydraulic CORE SURFACE DRILL models | Model-specific depth, tooling and local support |
| Epiroc | Christensen and Boyles surface rigs | Carrier, rod handling and service coverage |
| Boart Longyear | Surface coring rigs and tooling | Capacity for the intended rod specification |
| Comacchio | Crawler- and truck-mounted CX diamond rigs | Access, total weight and options |
| Sunny Corner Exploration | Surface rigs, parts and rebuilding | Regional spares and service response |
| Multi-Power Products | Portable and track-mounted core drills | Lift loads and transport modules |
| Massenza | Mineral-exploration and multipurpose rigs | Complete coring configuration |
| Dando Drilling | Coring and multipurpose exploration rigs | Method-specific equipment scope |
| PRD Rigs | Diamond-core and RC-capable exploration rigs | Distinct ratings for each method |
| Geomachine | Geological rigs with coring equipment | Exploration-boom and tooling compatibility |
CORTECH develops all-hydraulic diamond core rigs. Its CORE SURFACE DRILL range lists COREMASTER 500L, 1000L, 1300L, 1800X and 2200L. The company identifies COREMASTER 1800X as the former CSD1800X, useful when matching older quotations to current listings.
For a purpose-built surface package, ask CORTECH for depth by rod size, hoist and pullback ratings, rotation and pump specifications, operating weight and tooling scope. Request a written service plan for your destination country. Broad recovery or uptime claims need comparable field evidence; they are not guaranteed results.
Epiroc's Christensen and Boyles families cover surface coring. Christensen models have platform, trailer, crawler or truck options; certain machines offer rod handling. The Boyles C5/C5C separates into six principal modules for helicopter transport, according to Epiroc.
Ask for the specific carrier's footprint and lift plan. Epiroc's Diamec range serves underground exploration, so do not treat it as an equivalent surface quotation.
Boart Longyear supplies surface rigs and exploration tooling. Its LF90D product page states 1,193 m capacity with NRQ W-Wall rods, BQ-to-PQ compatibility, 111.8 kN pull force and a 71.2 kN main hoist.
That depth is not an HQ rating. Request the operating assessment for your actual rods, hole inclination and lifting procedure. Confirm how the quoted rig, core barrel and consumables fit together.
Comacchio offers crawler- and truck-mounted CX diamond rigs. Its product information describes core-barrel lengths up to 6 m and optional on-board rod handling.
Choose the carrier against the route, pad and ground conditions, not its appearance in a catalogue. Request complete transport dimensions and verify whether the rod handler is included in the bid.
Sunny Corner Exploration lists surface core rigs plus aftermarket parts, on-site service, inspection and refurbishment. Those services matter when a remote breakdown could halt a campaign.
Ask who provides local support, which critical parts are stocked and how a technician reaches your site. If replacing an older rig, compare a documented refurbishment proposal with the cost and lead time of a new machine.
Multi-Power Products lists helicopter-portable, track-mounted, man-portable and skid-mounted diamond core drills. Its range suits an access-focused shortlist.
A portable drill still needs rods, pumps, water, fuel and support equipment. Request a complete freight manifest showing each module's weight, the number of lifts and field-assembly requirements.
Massenza makes rigs for mineral exploration, geotechnical work and other applications. It says mineral-exploration selection depends on depth, diameter and ground type.
Specify the coring package: wireline winch, rotation head, clamp, pump, guarding and tooling interfaces. A bare multipurpose rig should not be price-compared with a fully equipped exploration machine.
Dando markets mineral-exploration rigs for coring, RC and rotary air blast. Its wider range includes water-well and geotechnical machines.
Request a coring-specific bill of materials identifying the head, mast, hoists, clamps and pump. Confirm which items are options and who handles training and parts support after export.
PRD lists surface exploration rigs for diamond coring and RC. Its range identifies BQ, NQ, HQ and PQ sizes for a diamond-core offering and separately lists a combined RC/diamond-core configuration.
If both methods matter, ask what conversion components are included. Never transfer an RC depth rating to a wireline core hole.
Geomachine says its larger geological rigs can serve exploration when fitted with a dedicated diamond-coring boom. Make that boom and the compatible wireline equipment explicit in the quotation.
For mixed geotechnical and exploration work, check method-change time, crew requirements and transport weight in both configurations.
A published maximum is not a universal hole-depth guarantee. Rod size changes string mass. Inclination, circulation loss, a blocked bit and in-hole drag can increase lifting load. Hydraulic pullback and main-hoist ratings describe different mechanisms; a hoist rope has its own safe working limit.
If a quote advertises "1,200 m," ask which rod, lifting method and conditions support the figure. Colin Rice's technical analysis shows why those distinctions can become safety issues. Have competent personnel check the proposed configuration against site conditions and applicable local requirements.
Record hole size and depth, but also pad dimensions, route grades, bridge limits, water availability and climate. Send every supplier the same site-access drawing. Ask them to identify assumptions about support vehicles, ground preparation and installation equipment; these can reveal hidden mobilization costs.
A safety-feature list cannot show how operators handle rods. Request a model-specific demonstration of loading, clamping, inner-tube retrieval and emergency stops. Confirm that any demonstrated guards or rod handlers are included in the delivered machine.
Estimate rig, transport, labor, fuel, consumables, maintenance and downtime costs, then divide by meters meeting your project's sampling criteria. This is your planning metric, not a manufacturer performance claim. Compare a normal case with a parts-delay scenario; the lowest purchase price need not produce the lowest program cost.
Before paying a deposit, ask for a critical-spares list, proposed stock location, replenishment times and a named escalation contact. Check which components the crew can replace on site and which need specialist tools or a workshop. Where the rig will be exported, clarify who handles customs documentation, commissioning and warranty work. These are questions to put to every supplier; do not infer a regional service level from a global marketing statement.
Send each supplier the same request for quotation (RFQ) to expose missing options and inconsistent assumptions.
1. Define the holes: Give depth, dip, core size, formations and recovery objectives.
2. Describe access: Include route, pad, water, climate and destination-country constraints.
3. Specify the method: List rods, core barrels, casing and any RC requirement.
4. Request rated data: Get rod-specific depth, pullback, hoist, rotation, pump and weight figures.
5. Audit handling: Ask about guards, controls, emergency stops and operator training.
6. Price the package: Separate rig, options, tooling, freight, spares and commissioning.
7. Check evidence: Obtain datasheets, a factory test plan and comparable customer references.
A reference from shallow, accessible drilling may not validate a deep, inclined, remote-hole proposal. Ask which model and conditions each reference actually covers.
The right supplier can document a safe, supportable configuration for your rod size, hole plan and site. Compare technical proposals and service commitments, not reputation alone.
For a CORTECH CORE SURFACE DRILL recommendation, send your target depth, BQ/NQ/HQ/PQ size, hole inclination, ground conditions, pad limits and destination country. Request a model-specific, itemized quotation, then assess it alongside other bids using the same checklist.
No. Concrete drills are intended for openings in constructed materials. Exploration core rigs are configured to recover geological samples from boreholes, often using wireline equipment. Confirm the application before building a supplier shortlist.
Different rod strings impose different loads and operating requirements. A published depth for one rod specification cannot safely be treated as a depth rating for every other size. Request the rating for the string you plan to use.
No. They refer to different lifting mechanisms. The rope fitted to a hoist and the applicable safe working limit must also be considered. Ask the OEM which mechanism supports its quoted drilling depth.
Consider one when road or pad access limits conventional transport. Verify the weight and size of every module, plus rods, pumps, fuel and assembly equipment, before planning lifts.
Choose based on your actual drilling program. A multipurpose machine can be attractive for varied work, but only if the quoted coring setup performs the required tasks and method changes are practical.
Get written details for local service contacts, critical-spares availability, lead times, operator training, warranty exclusions and escalation procedures. Confirm which partner is responsible in the destination country.
