Ghanaian businessman Ibrahim Mahama’s mining company, Engineers & Planners (E&P), is pursuing approximately $740 million from South African gold producer Gold Fields over alleged underpayments for services provided at two major mining operations in Ghana. The claims comprise $474.9 million relating to the Tarkwa mine and $264.7 million concerning the Damang operation, according to reporting by Miningmx and MarketScreener. E&P, which has worked at Gold Fields’ Ghanaian mines for more than two decades, argues that it is owed money for work carried out under its mining contracts. The dispute has advanced to arbitration in Ghana after E&P initiated formal proceedings. Gold Fields has rejected the claims, stating that it disagrees with E&P’s position and intends to defend itself against the allegations.
The dispute is unfolding during a significant restructuring of Ghana’s gold mining sector. E&P is owned by Ibrahim Mahama, the younger brother of President John Dramani Mahama, and was selected to take over the Damang mine after the Ghanaian government declined to renew Gold Fields’ previous operating lease. The transition has drawn scrutiny from opposition politicians and other industry stakeholders over local ownership policies and potential conflicts of interest. However, Ghana’s Minerals Commission has defended the tender process, saying E&P had provided services at Damang since 2004 and had pursued the concession before the current administration took office. The government has maintained that its mining reforms are intended to increase Ghanaian participation in the sector and ensure that more of the country’s mineral wealth benefits the domestic economy.
The $740 million dispute also comes as Gold Fields seeks to renew the mining leases for Tarkwa, one of its most important producing assets, with the existing leases due to expire in April 2027. The company has described regulatory uncertainty in Ghana as a material concern, while authorities have signalled that future lease renewals will depend on individual assessments of mining plans and investment commitments. In an October 2026 report, Miningmx noted that Gold Fields continues to pursue the Tarkwa renewal while contesting E&P’s claims. The arbitration’s outcome could have financial implications for both companies and influence wider investor perceptions of Ghana’s evolving mining framework. For the industry, the central issues include contractual enforcement, regulatory predictability and how Ghana balances greater local participation with the need to sustain long-term investment in its gold sector.
