Guinea launched the construction of the Chalco alumina refinery on the Lisso-Demougala site, located just over 40 kilometers from Boffa, on Saturday, June 13, 2026.
The ceremony was co-chaired by General Amara Camara, Secretary General of the Presidency, and Djiba Diakité, Chairman of the Strategic Committee of Simandou, in the presence of government representatives, industrial partners, and local communities.
According to information provided during the event, the project represents an estimated investment of one billion dollars and plans for a production capacity of 1.2 million tons of alumina per year.
This unit adds to the refinery projects led by SPIC and the Winning consortium in Dobali. With this new project, Guinea now has three alumina refinery projects underway as part of its policy to increase local processing of bauxite.
The agreements for the Chalco project were signed on May 21, 2026 in Conakry. The construction launch comes less than a month after this signing.
For Guinean authorities, the development of local refining capacities is part of a strategy to create added value within the national mining chain, with expected benefits in terms of jobs, training, and economic activity.
As the world’s leading producer of bauxite, Guinea has been seeking for several years to strengthen the local integration of its mining industry in order to reduce its dependence on exports of raw ore and increase the sector’s contribution to the country’s economic development.
