In July 2025, YG Machinery exported a diamond core drill rig to a mining contractor in Oman. The client explored copper and chromium deposits in the northern Hajar Mountains. Their old mechanical rig could not reach deep targets or handle the rugged, rocky terrain.
Our full hydraulic unit changed that quickly. The client drilled 40% faster and recovered cleaner cores in the first quarter. This case shows how the right diamond core drill rig lifts exploration speed and returns.

Diamond Core Drill Rig: Why an Omani Firm Chose YG
The short answer is depth, control, and mobility. A diamond core drill rig recovers solid rock cores for accurate assay work. A fully hydraulic system gives precise speed and reliable torque on hard formations.
The client ran one aging drill on large copper concessions. It advanced at most 20 meters per day in hard rock and jammed often. They needed a dependable unit that reached deeper targets and moved across steep ground.
They compared several suppliers over a five-week window. YG Machinery won on hydraulic reliability and a proven Middle East record.
Diamond Core Drill Rig: Project Background in Oman
Oman is a growing target for mineral exploration, with active copper, chromium, and gold projects. Rising metal prices pushed explorers to test deeper ore bodies. Many local contractors rely on older mechanical drills with limited depth.
The client held a large concession in the Hajar Mountains at high altitude. Their old rig reached only about 300 meters, missing deeper veins. Rocky gravel roads also forced slow moves between scattered sites.
Their management set clear goals before purchase:
- Drill to 600 meters or more reliably
- Move quickly between steep, remote sites
- Cut repair costs and unplanned downtime
- Recover clean cores for accurate assays
A crawler rig best matched these needs, as it climbs grades and avoids heavy towing.
Expert tip: For hard rock, prioritize hydraulic thrust control. It prevents jamming and protects core integrity.
The Solution: Diamond Core Drill Rig and Supplier Selection
Our engineers proposed the YGX-600 after studying the site. It offers up to 650-meter capacity and holds strong torque for hard rock. The full hydraulic drive gives smooth speed control and quick rod changes.
The client compared four suppliers on depth, build quality, and support over 45 days. YG Machinery won on hydraulic reliability and documented Middle East deliveries.
Key factors behind the decision:
- 650m drilling depth: Unlocked deeper, higher-value ore bodies
- Crawler mobility: Handles steep and rough terrain
- Multi-angle mast: 45°-90° range fits varied landforms
- Yuchai engine: Proven power and easy servicing
- Inclusive package: Mud pump, rods, and training included
We supplied one YGX-600, a hydraulic mud pump, drill rods, and a full spares kit.
Full Hydraulic Core Drilling Rig Specifications
The YGX-600 is a full hydraulic core drilling rig built for deep exploration in rough terrain. Its power pack, mast, and drive all use hydraulics for smooth, reliable operation.
| Model | YGX-400 | YGX-600 | YGX-800 | YGX-1000 |
|---|---|---|---|---|
| Drilling Depth (M) | 180-400-500 | 200-600-650 | 400-800-1000 | 500-1000-1100 |
| Rated Pressure (MPa) | 21 | 21 | 25 | 28 |
| Rated Flow (L/min) | 168 | 192 | 260 | 300 |
| Engine Brand | Yuchai | Yuchai | Yuchai | Cummins |
| Rated Power/Speed | 78kW/2400r/min | 92kW/2400r/min | 92kW/2400r/min | 154kW/2400r/min |
| Drilling Angle (°) | 0-90 | 45-90 | 45-90 | 45-90 |
| Lifting Force (T) | 12 | 16 | 24 | 30 |
| Feed Force (T) | 6 | 8 | 12 | 15 |
| Mud Pump Flow (L/min) | 30-90 | 30-90 | 90-180 | 90-180 |
| Mud Pump Power (MPa) | 4-7 | 4-7 | 4-7 | 4-7 |
| Dimension (mm) | 4000×1900×1800 | 4000×2000×1800 | 5500×2100×2000 | 6000×2200×2400 |
| Weight (T) | 4.3 | 4.5/5.5 | 6.5 | 7.5 |
The series covers depths from 400 to 1,100 meters. Explorers match the rig to target depth and rock hardness. For copper veins past 500 meters, the YGX-600 is a solid fit.
Expert tip: Confirm the mud pump matches your hole depth. A deep mining core drilling rig needs enough mud flow to lift cuttings and cool the bit.
Shipping the Diamond Drill Rig to Oman
The YGX-600 was shipped from Shanghai to the Port of Sohar. We disassembled the mast, power pack, and trailer for safe packing in a 40-foot container.
Sea freight and customs clearance were completed in 24 days. YG handled export documents, while our Oman partner managed local clearance and delivery.
Project timeline:
- Day 1-3: Contract signed and deposit confirmed
- Day 4-12: Production, assembly, quality inspection
- Day 13-15: Steel-cradled container packing
- Day 16-36: Sea freight to Sohar + customs
- Day 37-40: Overland delivery to Hajar site
- Day 41-44: Reassembly, test runs, training
- Day 45: Acceptance and handover signed
The rig moved onto the graded pad under its own power. Assembly took only three days with YG’s remote support.
Import tip: Verify the HS code and duty rate for drilling machinery early. Payments follow the shipment milestones in the contract.
Installing and Commissioning the Diamond Drilling Rig
YG engineers joined the site on day 41 and finished commissioning in three days. Work covered power setup, rod handling, test holes, and operator training.
Four-phase commissioning:
- Power setup (6h): Engine checked, hydraulics primed
- Mast alignment (8h): Angle set, hydraulic lines tested
- Test drilling (10h): Two test holes, parameters tuned
- Operator training (12h): Four drillers certified
By day 58, crews ran the rig at full depth independently. The first 200-meter production hole passed with clean, intact cores.
Expert tip: Work in the cooler morning shift. This lowers engine load and preserves core quality in intense heat.
Operating Results of the Mining Core Drilling Rig
After five months, the YGX-600 drilled over 3,600 meters across eight holes. Core recovery averaged 95%, and the rig handled deep targets with ease.
Measured results:
| Metric | Before | After |
|---|---|---|
| Max hole depth | 300 m | 550 m+ |
| Drilling rate | 20 m/day | 35 m/day |
| Core recovery | 80% | 95% |
| Uptime | 74% | 96% |
| Repair cost | high | cut by 60% |
ROI followed quickly. Landed cost was about $175,000, including freight and training. Monthly revenue from faster, deeper drilling added $30,000. The rig paid for itself in under six months.
Expert tip: Compare landed cost, not just price. Include freight, duty, spare kits, and training to judge real value.

Diamond Core Drill Rig: Customer Feedback
The drilling manager, Mr. Al-Balushi, rated the rig 9.3 out of 10 and praised its reliability in the mountains.
“The hydraulic system just runs. We push it daily, and it has never jammed on a hole. The 600-meter capacity opened targets we could not reach,” he said.
He valued YG’s support too. “When we needed a spare valve, YG shipped it within a week. That keeps a modern mine moving.”
The firm ordered a second YGX-600 for a new chromium concession next quarter.
Buying Advice for a Diamond Core Drill Rig
Choosing a diamond core drill rig affects exploration speed, safety, and cost. Based on many mining shipments, here are proven tips.
- Match depth to target: Oversizing wastes money; undersizing loses ore
- Confirm terrain fit: Steep sites need a crawler with real climbing power
- Check mud pump size: It must match hole depth and ground conditions
- Verify spares availability: Remote mines need fast parts delivery
- Compare landed cost: Include freight, duty, and installation fees
- Demand training: Skilled crews double drilling efficiency
A supplier that knows mining import rules saves weeks. YG Machinery delivers documented shipments and training across the Middle East.
