Chairman Wontumi Sentenced to 20 Years for Illegal Mining as High Court Signals Zero Tolerance on Galamsey

The Accra High Court has delivered a landmark verdict in one of Ghana's most high-profile illegal mining prosecutions, sentencing NPP Ashanti Regional Chairman Bernard Antwi-Boasiako, known as Chairman Wontumi, to 20 years imprisonment for orchestrating unlicensed mining operations on the Samreboi concession in the Western Region. Justice Audrey Kocuvie-Tay imposed the custodial sentence on Monday, 20 July 2026, alongside a fine of GH¢120,000 (10,000 penalty units), with a default three-year jail term if the fine remains unpaid.

Antwi-Boasiako was found guilty on all six counts, including unlawfully assigning mineral rights and knowingly facilitating mining without a licence in breach of the Minerals and Mining Act, 2006. The 20-year term sits within the statutory range of 15 to 25 years prescribed for such offences, with Justice Kocuvie-Tay rejecting defence pleas for leniency despite arguments that the defendant showed remorse, cooperated with investigators, maintained a clean criminal record, and had contributed meaningfully to his community.

The case centred on a police anti-galamsey operation at Samreboi on 16-17 April 2025, which uncovered 25 excavators, firearms, vehicles and GH¢157,000 in cash. The prosecution successfully proved that Antwi-Boasiako, as owner and controlling director of Akonta Mining Company Limited, permitted mining without ministerial approval—a flagrant violation of Ghana's mining regulations. His defence team contended that persons found on site were engaged only in land reclamation and coconut farming, a claim the court rejected.

The significance of this ruling

This conviction represents a watershed moment in Ghana's battle against illegal small-scale mining, commonly known as galamsey. For years, the sector has ravaged water bodies, destroyed arable land and endangered public health whilst high-profile figures escaped accountability. The fact that a sitting regional chairman of a major political party has received a substantial custodial sentence signals that no one—regardless of political affiliation or social standing—is above the law when it comes to environmental crimes.

The court's decision to reject mercy pleas and impose a term closer to the maximum available range demonstrates judicial resolve to deter similar conduct. By contrast, the court showed restraint with Akonta Mining Company Limited, imposing only financial penalties rather than corporate dissolution, though the company still faces potential forfeiture of all recovered assets including the excavators and cash.

What this means for Ghana's galamsey crackdown

Ghana has long struggled with the dual challenge of regulating artisanal and small-scale mining whilst combating organised illegal operations that cause ecological devastation. The Wontumi case demonstrates that law enforcement and the judiciary are prepared to prosecute offenders at the highest levels of society. This verdict should serve as a stark warning to other politically connected figures tempted to profit from environmental crime.

The court's forthcoming ruling on forfeiture of the GH¢157,000 in cash and equipment recovered from Samreboi will further test government resolve. If the assets are surrendered to the state, it will signal that proceeds of galamsey cannot be retained or shielded through corporate structures.

However, a single high-profile conviction, whilst symbolically important, cannot solve a systemic problem. Galamsey continues to flourish in many parts of Ghana because of weak enforcement in remote areas, corruption within regulatory bodies, and the poverty-driven desperation of communities near mineral-rich zones. Sustained investment in legitimate alternatives, community engagement, and consistent prosecution across all social classes—not just prominent figures—will be essential if this verdict is to mark a genuine turning point rather than an isolated victory.
