The Koné Gold Project is a major gold mining development in Côte d’Ivoire, West Africa, developed by Montage Gold Corp.
The project is designed as a large-scale open-pit gold mine and processing operation, with a planned mine life of approximately 16 years. Construction commenced in December 2024, with first gold production targeted for the end of the fourth quarter of 2026.
A key part of the project infrastructure is its high-voltage electrical power supply system, which connects the mine to Côte d’Ivoire’s national electricity grid through a new 225 kV transmission connection.
The project includes a new 225 kV substation equipped with two 85 MVA power transformers, providing a total installed transformer capacity of 170 MVA.
The Lafigué Mine is a major gold mining operation located in the north-central region of Côte d'Ivoire, approximately 330 km north-northwest of Abidjan.
The mine is operated by Lafigué Mining and uses open-pit contractor mining and a Carbon-in-Leach (CIL) processing plant. Construction began in Q4 2022, with first gold poured in Q2 2024.
For large-scale mining operations, reliable electrical infrastructure is essential for supporting mining, mineral processing and associated site facilities.
Choosing the right power transformer is an important decision for any electrical power system. The transformer must match the required voltage, power capacity, operating environment, load characteristics, and applicable standards.
An incorrectly selected transformer can lead to energy losses, overheating, reduced equipment life, unexpected downtime, and higher operating costs.
