Ghana’s push to tighten control over its mining sector is beginning to unsettle investors, with industry leaders warning that uncertainty around mining leases could damage confidence in Africa’s largest gold-producing nation.

The warning comes as Ghana increases pressure on foreign mining firms while trying to secure a bigger share of soaring global mineral revenues.

Kenneth Ashigbey, chief executive of the Ghana Chamber of Mines, said recent government actions, including revoked leases, delayed renewals and shifting mining policies, are creating concerns about whether mining companies can rely on long-term protections in the country.

Speaking to Reuters, Ashigbey said the situation risks sending a dangerous message to global investors that “security of tenure in Ghana is not guaranteed.”

At the centre of the dispute is the future of the Tarkwa mine operated by Gold Fields, one of the company’s most important assets globally.
