Wontumi jailed for 20 years over illegal mining as Ghana court delivers landmark ruling
Bernard Antwi Boasiako, known as Wontumi, has been sentenced to 20 years in prison after a High Court convicted him over illegal mining offences involving Akonta Mining. Here's what the ruling means.
A High Court in Accra has sentenced Bernard Antwi Boasiako, popularly known as Wontumi, to 20 years’ imprisonment with hard labour after convicting him of illegal mining-related offences. The ruling is expected to become one of Ghana’s most significant legal precedents in the fight against illegal mining and corporate accountability.
ACCRA, Ghana – A High Court in Accra has sentenced Bernard Antwi Boasiako, popularly known as Wontumi, to 20 years’ imprisonment with hard labour after convicting him of illegal mining-related offences involving Akonta Mining Company Limited.
Justice Audrey Kocuvie-Tay delivered the judgement on Monday after concluding that Boasiako and Akonta Mining Company Limited had unlawfully assigned mineral rights without the approval required by law and had purposely facilitated an unlicensed mining operation on the company’s concession in the Western Region.
The ruling is among the most consequential criminal judgements delivered under Ghana’s campaign against illegal mining, commonly known as galamsey, an activity successive governments have identified as a major driver of river pollution, forest destruction and environmental degradation. Boasiako, who serves as Ashanti Regional Chairman of the opposition New Patriotic Party (NPP), was tried alongside Akonta Mining Company Limited. A third accused, Kwame Antwi, remained at large and was tried in absentia.

Why the Court Convicted Wontumi
The prosecution’s case was that Akonta Mining permitted another party to conduct mining on part of its concession without first obtaining the statutory ministerial approval required under Ghanaian mining law.
Akonta Mining held a valid mining lease. However, the prosecution argued that this did not authorise the company to transfer or assign mining rights to another operator without approval.
Evidence during the trial centred on an arrangement involving Henry Okum, who testified that he had been authorised to reclaim previously mined land while financing those works through proceeds generated from gold extraction.
The prosecution argued that the arrangement enabled unlicensed mining to continue under the description of land reclamation.
Justice Kocuvie-Tay accepted that argument and found that mining activity had been authorised without the statutory approvals required under the Minerals and Mining Act.
The court concluded that the evidence established criminal responsibility beyond reasonable doubt.
How the Prosecution’s Case Was Constructed
-
01
Akonta Mining held the concession
The company possessed a mining lease covering the relevant land.
-
02
A third party was permitted to operate
The prosecution said another operator was allowed to undertake activities on parts of the concession.
-
03
Gold extraction financed the arrangement
Evidence indicated that proceeds from mining were intended to fund reclamation work.
-
04
Ministerial approval was absent
The court found that the statutory approval needed for the arrangement had not been obtained.
-
05
Criminal responsibility was established
The judge concluded that the evidence proved the relevant offences beyond reasonable doubt.
Defence Arguments Rejected
Boasiako denied authorising illegal mining throughout the proceedings.
His legal team argued that permission had been granted only for land reclamation and coconut cultivation.
The defence maintained that any mining subsequently undertaken occurred without his approval or knowledge.
The court rejected that explanation.
Justice Kocuvie-Tay held that the surrounding evidence, including the financial arrangements described during the trial, showed that mining formed an integral part of the agreement rather than an unauthorised activity carried out independently.
Corporate Liability
One of the judgment’s most significant legal findings concerned the relationship between Akonta Mining’s corporate personality and Boasiako’s personal responsibility.
Companies ordinarily exist as separate legal entities. That principle generally distinguishes the company’s rights and liabilities from those of its shareholders, officers and directors.
In this case, however, the court concluded that Akonta Mining’s corporate structure did not shield Boasiako from personal criminal liability because he exercised effective control over operations relating to the concession.
The judgment found that the company’s internal governance arrangements were insufficient and that decisions concerning the concession were effectively directed by Boasiako himself.
The court therefore looked beyond the company’s separate legal identity when determining criminal responsibility.
Sentence Imposed
The court imposed custodial sentences, financial penalties and forfeiture orders.
Imprisonment with hard labour
Imprisonment with hard labour
- 10,000 penalty units Fine imposed on Boasiako on each count
- 15,000 penalty units Fine imposed on Akonta Mining Company Limited on each corporate count
- Property forfeiture Excavators, vehicles, cash and other property seized during police operations were ordered forfeited to the State
Why the Ruling Matters
Illegal mining remains one of Ghana’s most serious environmental, governance and public-policy challenges.
Successive governments have launched enforcement operations, strengthened regulation and pursued criminal prosecutions in an effort to curb unauthorised mining.
Illegal mining has been associated with pollution of major rivers, destruction of forest reserves, degradation of cocoa-growing land and substantial economic losses.
The High Court’s interpretation of concession-holder responsibilities under the Minerals and Mining Act is therefore likely to be examined closely by mining companies, regulators, lawyers and environmental campaigners.
The judgment reinforces the proposition that holders of mining concessions may face criminal liability where third parties are allowed to operate without the approvals required by law.
