In June 2024, YG Machinery delivered a core sample drill rig to a mineral exploration contractor in Sabah, Malaysia. The client specialized in gold and copper prospecting across Borneo’s mountainous terrain. Their outdated rotary rig struggled with hard granite and produced low-quality core samples. After evaluating four suppliers, they chose YG Machinery for technical capability and price.
This fully hydraulic crawler core drilling rig delivered 3x faster penetration and 95% core recovery in hard rock. YG provided site commissioning, operator training, and a six-month spare parts package for remote Malaysian conditions.

Core Sample Drill Rig Project Background in Malaysia
Malaysia’s mineral exploration sector has grown steadily since 2023, driven by copper and gold demand. Sabah and Sarawak host over 40 active projects across mountainous terrain with limited road access. Most local contractors still use older rotary rigs ineffective in hard igneous rock.
The Penang-based exploration company with 35 staff worked on a gold prospecting project in Sabah’s Crocker Range. Their aging rotary rig drilled only 50-80 meters deep into granite. Core recovery hovered around 55-60%, making geological assessment unreliable and slowing resource estimation.
The remote site added operational complexity. Access required 4×4 vehicles and transport took 8 hours from the nearest town. Breakdowns meant days of downtime waiting for parts. The client lost an estimated RM 65,000 monthly to low productivity.
Expert tip: For jungle sites, choose crawler-mounted rigs with compact dimensions. They handle steep terrain and narrow logging roads better.
Core Sample Drill Rig Solution and Supplier Selection
The client found YG Machinery searching for a core drilling rig manufacturer and requested a proposal. They compared our rigs against Chinese, Australian, and local suppliers. After reviewing demos and references, they chose our YGX-600 model.
Key decision factors:
- Proven hard-rock performance: 25+ active rigs in Indonesia and Philippines granite
- Crawler mobility: Rubber-track chassis handles 30° slopes and jungle tracks
- Spares package: 6-month critical parts inventory included as standard
- On-site commissioning: Senior technician for 10-day setup and training
- Competitive pricing: 30% lower than comparable Australian rigs
Our transparent technical documentation also stood out. We provided full English service manuals with hydraulic schematics. This enabled their technicians to perform routine maintenance independently.
Core Sample Drill Rig Specifications
The YGX-600 is a fully hydraulic crawler core drilling rig built for mineral exploration. Its 92kW Yuchai engine delivers steady power in tropical heat. It handles 200- 650 m depths with BQ/NQ/HQ rods.
| Parameter | YGX-400 | YGX-600 | YGX-800 | YGX-1000 |
|---|---|---|---|---|
| Drilling Depth (m) | 180-400-500 | 200-600-750 | 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 | 78kW | 92kW | 92kW | 154kW |
| 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 | 30-90 | 30-90 | 90-180 | 90-180 |

| Weight | 4.3T | 4.5T | 6.5T | 7.5T |
At 4.5 tons, the YGX-600 balances drilling capacity with transportability. Its 4-meter length fits a 20ft container, and the crawler navigates jungle roads easily. For multi-site contractors, this balance improves project economics significantly.
Pro tip: Specify tropical-grade hydraulic fluid (ISO VG 46) and 15W-40 oil for 30-35°C operating conditions.
Core Sample Drill Rig Shipping and Installation
The core sample drill rig shipped from Guangzhou to Port Klang via a 20ft container. Sea freight took 8 days, with customs clearance in 3 days. YG handled all export documentation, including invoice, packing list, bill of lading, and ASEAN-China FTA certificate.
Project timeline:
- Day 1-5: Contract signing and 30% deposit
- Day 6-25: Production and factory test bore
- Day 26-28: Disassembly and container packing
- Day 29-37: Sea freight + customs clearance
- Day 38-42: Road transport to Sabah site
- Day 43-52: Assembly, commissioning, and training
- Day 53: Performance test and acceptance
Customs tip: Prepare HS code 84304100 docs. Apply for MITI import permit for 0% duty on mining equipment.
Core Sample Drill Rig Commissioning Process
Our senior technician arrived on day 43 and completed commissioning in 10 days. The process included crawler assembly, mast erection, hydraulic connection, engine tuning, safety checks, and operator training. The client assigned two drillers, one mechanic, and one geologist.
Five-phase commissioning:
- Mechanical assembly (2d): Track installation, mast erection, hose connection
- System calibration (1d): Pressure testing, flow adjustment, hoist calibration
- Safety verification (1d): Stop tests, guardrail checks, fall protection review
- Test drilling (3d): 150m test hole, recovery verification, speed optimization
- Operator training (3d): Technique, maintenance, troubleshooting, safety
By day 52, the head driller operated the rig independently at full capacity. The 150m test hole achieved 96% core recovery, exceeding the 85% target. We provided English manuals, maintenance schedules, and a 20+ video library.
Core Sample Drill Rig Operation Results
After three months of exploration, the rig completed 12 boreholes totaling 3,200 meters with 94% core recovery. Average penetration hit 25 meters per shift in hard granite — three times faster than the old rotary rig. Crawler mobility cut relocation from 2 days to 4 hours.
Key improvements:
- Drilling speed: 3x faster in hard granite than previous rig
- Core recovery rate: Improved from 58% to 94% average
- Relocation time: Cut from 48 hours to 4 hours with crawler
- Downtime: Only 2 days of scheduled maintenance in 3 months
- Depth capability: Expanded from 80m to 650m maximum
Better core quality also accelerated geological assessment. Geologists mapped mineralization with greater confidence, reducing confirmation drilling by 30%. The project reached resource calculation two months ahead of schedule.
Core Sample Drill Rig ROI Analysis
Investing in a quality rig requires significant capital for Malaysian contractors. Working with an experienced core drilling rig manufacturer ensures reliable performance and support. For this client, total landed cost was approximately RM 480,000 ($105,000 USD). Productivity gains delivered full ROI well within the first year.
ROI breakdown:
- Total investment: RM 420,000
- Monthly revenue gain: RM 90,000 (3x more meters drilled)
- Monthly labor savings: RM 12,000 (crew reduced from 6 to 4)
- Monthly quality savings: RM 18,000 (less re-drilling)
- Total monthly gains: RM 120,000
- ROI period: ~4 months
This excludes strategic value from winning larger contracts. The client secured two additional Sarawak projects thanks to their new capability. They plan to buy a YGX-800 for deeper drilling in 2026.
Customer Feedback and Key Results
Three months after commissioning, we reviewed satisfaction with operations manager Mr. Tan. He highlighted drilling performance and training quality as top value points.
“The rig handles our hardest granite without struggle. Core recovery stays above 90%, which makes our geologists happy. Our team was independent by day 8.”
Mr. Tan also valued the spare parts package. “We had one seal leak in month two. The part was in our starter kit, so we fixed it in hours. Our old supplier would have made us wait two weeks.” He rated the experience 9/10.

Core Sample Drill Rig Buying Advice
Choosing the right core drilling equipment impacts project economics and data quality. Here are key factors for Malaysian buyers.
Critical purchasing considerations:
- Match depth to targets: Choose a rig rated 20-30% deeper than planned max. Granite wears equipment faster.
- Prioritize mobility: Crawler rigs handle Sabah/Sarawak terrain better than skid or truck-mounted units.
- Check parts availability: Downtime in remote areas costs far more than the rig. Confirm local stock or fast air freight.
- Evaluate training: Driller skill determines 40% of core quality and rig lifespan. Prefer on-site training.
- Total ownership cost: Cheaper rigs cost more long-term through lower recovery and more breakdowns.
Work with a supplier that understands regional geology and regulations. Familiarity with local procedures saves weeks of import delays.
