Case Study: Metal Exploration Project in Guanajuato, Mexico
Client Background: A drilling company in Sausato, Guanajuato, Mexico, specializing in mineral exploration technical services (orebody delineation, resource reserve assessment), is undertaking multiple metal mineral exploration projects in Latin America. The company’s previous use of various brands of drilling rigs generally suffered from insufficient power, low deep-hole efficiency, high failure rates, and poor core integrity. Considering the characteristics of the Latin American market, the company purchased a YG hydraulic core drilling rig for the project in May 2025. Due to the equipment’s superior performance, the project was successfully completed. Subsequently, the company ordered another rig of the same model, fully demonstrating its confidence in the equipment.
Construction Challenges:
- This project requires single-hole drilling depths exceeding 1000 meters. Traditional drilling rigs lack sufficient power, and the hard strata easily cause the drill bit to get stuck or clog, resulting in low efficiency and difficulty in completing the project on schedule.
- The complex lithology (including metamorphic and fractured altered rocks) means that traditional drilling rigs easily disturb the rock core, causing core breakage and detachment, leading to low recovery rates and an inability to provide accurate reserve assessment samples.
- Guanajuato, Mexico, has a unique climate (hot and dry, with large diurnal temperature variations and occasional heavy rains). Traditional drilling rigs have insufficient hydraulic system protection, making them prone to problems such as poor heat dissipation, component aging, and moisture-related malfunctions, unable to withstand 20 hours of high-intensity operation per day.
- The tight schedule, coupled with the cumbersome operation of traditional drilling rigs, the need for multiple operators, long auxiliary times, low efficiency, and a high risk of delays.
Solution:
- The tracked hydraulic core drilling rig boasts powerful performance, high torque, and strong lifting capacity, meeting drilling requirements exceeding 1000 meters. Equipped with high-rigidity direct-drive drill pipe, it reduces vibration, prevents stuck drill pipe and engine stall, and ensures stable deep-hole drilling.
- Utilizing a load-sensing control system and electro-hydraulic pilot proportional control technology, it automatically adjusts torque and speed according to formation hardness. A dedicated wire rope coring tool eliminates the need to lift the entire drill pipe, reducing core breakage and improving core integrity.
- Equipped with an independent, high-efficiency cooling system and moisture-proof sealing device, and optimized hydraulic protection design, it maintains 98% power retention even in extreme environments ranging from -30℃ to 50℃, enabling continuous high-intensity operation for up to 20 hours per day without suffering from poor heat dissipation or moisture damage.
- Its integrated design, equipped with a wireless remote control, allows for single-person remote operation, reducing the number of operators. Optimized structure enhances relocation flexibility, shortens commissioning and auxiliary time, and improves construction efficiency.
Results: Through the deployment of the YG fully hydraulic core drilling rig and the implementation of customized solutions, the project’s construction efficiency, core quality, and equipment stability were significantly improved, successfully completing the exploration task. All indicators far exceeded expectations, creating considerable economic benefits and project value for the client. Specifically, the final drilling depth per hole reached over 1100 meters, the core recovery rate consistently remained above 95%, the overall construction cost was reduced by more than 35% compared to traditional drilling rigs, the failure rate was reduced by more than 75%, and there were no delays in the project schedule due to equipment failure. Furthermore, after the project was completed, the client immediately placed an order for a second YG hydraulic core drilling rig, laying a solid foundation for long-term cooperation.
Customer Testimonial:
“YG’s hydraulic core drilling rig is powerful and stable. It not only broke our project’s single-hole efficiency record but also produced complete, high-quality core samples, providing strong support for our resource reserve assessment. The equipment also demonstrated excellent adaptability to extreme weather, capable of withstanding 20 hours of high-intensity operation per day, with an extremely low failure rate, significantly reducing our construction costs and schedule pressure. We have already ordered a second unit and will continue to cooperate with your company to provide reliable equipment support for our exploration projects in Latin America!” – Project Manager, Drilling Company, Guanajuato, Mexico
