Oko Gold Mines
Cuyuni Mining District, Guyana
The Oko Gold Mines Project is a large-scale mining development in northwest Guyana expected to produce approximately 350,000 ounces of gold annually over a projected 12.3-year mine life. Backed by an initial investment exceeding $972 million USD, the project includes both open-pit and underground mining operations supported by a dedicated 56 MW power plant. Once operational, Oko will become one of the most significant new gold mining operations in the region.

More About This Project:
The Oko Gold Mines Project represents a major mining development in the Cuyuni Mining District of Guyana, combining open-pit and underground mining to unlock a high-grade gold deposit. With construction beginning in late 2025, the project involves extensive site infrastructure, processing facilities, and power generation to support long-term production. Once operational, the mine is expected to produce approximately 350,000 ounces of gold annually, positioning it as one of the region’s most important new mining operations.
Developing a project of this scale in a relatively remote location presents significant logistical challenges. Limited local supply capacity required the project team to coordinate large volumes of international procurement while managing complex transportation and workforce mobilisation efforts. Successfully navigating these constraints required early planning, structured logistics coordination, and careful alignment with local cultural and business practices to ensure smooth project execution.
Through disciplined project management and strong coordination, G Mining Services has maintained steady project momentum while managing supply chain risks and supporting workforce growth. With construction ramping up and major permits secured on schedule, the project continues progressing toward construction completion in 2027 and commercial production beginning in 2028.
