B2Gold announced that its Fekola gold mine would be upgraded with 30 MW solar by 2020.
The mine that is located in Mali currently runs on heavy-fuel oil. The addition of the solar power plant and a "significant battery storage component" is estimated to cost around USD38 million and has a four-year payback period. The project is scheduled for completion in August 2020. For B2Gold it will be the second off-grid solar power plant, after having inaugrated in May 2018 the Otjikoto gold mine solar plant, in Namibia.
