In June 2025, a leading mining company in Ghana successfully purchased a rc drilling from YG Machinery to enhance their copper and gold exploration projects. The company needed a reliable, high-efficiency drilling solution capable of handling Ghana’s rugged terrain and complex geological formations. After evaluating several options, they chose YG’s reverse circulation drilling rig due to its cost-effectiveness, precision, and proven performance in West African mining sites.
Client Challenges and Requirements
Ghana’s mining areas often involve hard rock, gravel, and uneven surfaces, which can reduce drilling efficiency and increase operational costs. The client specifically faced these challenges:
- Inconsistent core recovery rates from previous equipment, affecting geological analysis accuracy.
- Limited on-site technical support for imported rigs, causing frequent downtime.
- High operational costs due to excessive fuel consumption and maintenance.
- Need for fast drilling to meet tight project timelines for multiple exploration sites.
They required a rc drilling machine that could overcome these challenges while delivering reliable performance under harsh conditions.

Project Implementation and Performance
The rc rig was deployed across three mining sites in the Ashanti and Western regions. Key outcomes included:
- Efficiency increase: Average drilling speed improved by 25% compared to previous rigs.
- Core recovery: Consistently over 95%, providing reliable samples for mineral assay.
- Operational uptime: The rig ran 1,500 operational hours in 2025 with minimal maintenance.
- Fuel savings: Intelligent hydraulic system reduced fuel consumption by approximately 18%.
According to the client, “The rc drilling from YG Machinery exceeded our expectations in both reliability and drilling precision. It is easy to operate, and maintenance cycles are shorter than previous rigs.”
Why Reverse Circulation Drilling Machines Are Cost-Effective?
Investing in a rc drill rig brings long-term savings due to:
- High core recovery reducing repeat drilling costs.
- Efficient hydraulic feed system minimizing fuel and operational expenses.
- Durable components with easy access to spare parts.
- Quick deployment and mobility, reducing project downtime.
For Ghanaian mining companies, this translates into faster project completion, lower per-meter drilling costs, and higher accuracy in mineral exploration.
Considerations When Choosing an RC Drill Rig
When selecting a reverse circulation drilling rig for sale, clients should evaluate:
- Drilling depth requirements: Match the rig’s maximum depth to the target mineral zones.
- Geological conditions: Ensure the rig handles local rock hardness and terrain.
- Mobility needs: Trailer-mounted or crawler-based rigs improve site transfer efficiency.
- Support and parts availability: YG provides spare parts stock and 24/7 technical support.
