Ghana’s mining titan, Sir Sam Jonah, has been appointed as the new chair of the Nkamouna-Lomié cobalt mine in Eastern Cameroon.
The mine, one of the largest deposits of its kind in the region, is operated by Geovic Cameroon, a subsidiary of the U.S.-based Phoenix Mining.
With this appointment, Jonah takes on a crucial role at the mine, which boasts significant reserves of cobalt, nickel, and manganese, marking a substantial step in his career that once saw him at the helm of Ghana’s AngloGold Ashanti, one of the world’s top gold mining operations.

Jonah’s appointment comes as he replaces Canadian Serin Christopher, with his term set to commence at the end of October 2024. According to reports by the Cameroonian news source EcoMatin, the mine holds an estimated 68.13 million tonnes of ore, accentuating the importance of Jonah’s new role. This mining project is expected to be a boon for both Geovic and Cameroon, as demand for cobalt, a critical component in batteries and various high-tech industries, continues to surge.
Besides its well-documented oil and gas resources, Cameroon is endowed with abundant mineral wealth, including aluminum, diamonds, bauxite, and iron ore. The Nkamouna-Lomié deposit further highlights this country’s richness in minerals, with cobalt reserves playing a significant role in the global market. Cameroon’s estimated bauxite reserves, for instance, exceed one billion tons, indicating the potential for growth and expansion in its mining sector.
Jonah’s experience in leading major mining ventures across Africa, including his tenure at AngloGold Ashanti, has made him a pivotal figure in the industry. His leadership at the Nkamouna-Lomié site is anticipated to bring insight, expertise, and potentially greater international interest in Cameroon’s mining landscape. Known for his strategic mindset, Jonah’s influence is expected to be transformative for both the mine and the broader sector.
Some experts say the appointment of Sam Jonah to such a high-profile role marks an important connection between West and Central Africa in the mining arena, showcasing the potential of African-led management of key mineral resources.

With cobalt’s role in the renewable energy transition, industry watchers believe this move could pave the way for further African leadership in mining and resource development.
As Cameroon seeks to attract investment and strengthen its mineral exports, the appointment of a figure of Jonah’s stature could provide a competitive edge. His extensive experience and leadership could prove instrumental in advancing the Nkamouna-Lomié project and spotlighting Cameroon’s role in the global mining sector.
