The Accra High Court has sentenced Bernard Antwi-Boasiako, popularly known as Chairman Wontumi, to 20 years in prison. The New Patriotic Party (NPP) Ashanti Regional Chairman received the sentence for illegal mining activities on the Samreboi concession in the Western Region.
Justice Audrey Kocuvie-Tay delivered the sentence on Monday, July 20, 2026. The court also imposed a fine of 10,000 penalty units, equivalent to GHS 120,000. Failure to pay the fine will result in an additional three years' imprisonment. Both the custodial sentence and the default term will run concurrently, meaning they are served at the same time.
This conviction marks a significant moment in Ghana's fight against illegal mining, locally known as 'galamsey'. The practice causes severe environmental degradation, pollutes water bodies, and leads to significant economic losses. The government has intensified efforts to curb these activities, with this high-profile case demonstrating a commitment to enforcing mining laws regardless of political affiliation. This ruling could deter others involved in similar illicit operations.
Justice Kocuvie-Tay found Mr. Antwi-Boasiako guilty on six counts. These charges included assigning mineral rights without approval and purposely facilitating an unlicensed mining operation. These actions violated the Minerals and Mining Act, 2006 (Act 703), as amended. The 20-year sentence falls within the statutory range of 15 to 25 years for such offences.
The court showed leniency towards Akonta Mining Company Limited, a firm linked to Mr. Antwi-Boasiako. The company faced similar charges but received a financial penalty instead of a custodial sentence. The court considered mitigating circumstances for the company. This decision means the company will not receive the same imprisonment punishment as its controlling director.
Mr. Antwi-Boasiako’s lawyers, led by Samuel Atta Akyea, pleaded for a lighter sentence. They asked the court to consider the minimum sentence of 15 years. The defence argued that Mr. Antwi-Boasiako had shown remorse and cooperated with investigators. They also highlighted his consistent appearance in court throughout the trial. The lawyers described him as a family man with no prior criminal record. They also noted his contributions to his community and the country. However, the court imposed the 20-year term after reviewing submissions from both the defence and prosecution.
The case originated from a police anti-illegal mining operation at the Samreboi concession. This operation occurred on April 16 and 17, 2025. Authorities arrested Michael Ayisi Gyedu and 28 others during the operation. They recovered 25 serviceable excavators, firearms, vehicles, and GHS 157,000 in cash. The prosecution maintained that Mr. Antwi-Boasiako, as owner and director of Akonta Mining Company Limited, allowed mining without ministerial approval. The defence claimed Mr. Antwi-Boasiako never authorized mining. They stated that individuals on the concession were only involved in land reclamation and coconut plantation activities. The Republic is also seeking a forfeiture order for the seized items, including excavators and cash. The court will rule on this application later.
This ruling sends a strong message to individuals and companies involved in illegal mining. It reinforces the government's resolve to protect Ghana's natural resources. The outcome will likely influence future enforcement actions and investment in the mining sector. It also highlights the legal risks associated with non-compliance with mining regulations. Stakeholders will closely watch the implications for political figures and the broader business community.
