Ghana’s Environmental Protection Authority (EPA) has intensified its scrutiny of mining operations. Recent actions involve Earl International Group, Cardinal Namdini Mining and Gold Fields’ Tarkwa mine. The EPA also fined AngloGold Ashanti’s Iduapriem operation for environmental breaches in 2025, according to Reuters.
The cases carry different regulatory implications. The EPA ordered Earl International to stop operating before the company said it had received clearance to resume. Cardinal Namdini received a pre-closure notice over an alleged reporting failure. At Tarkwa, the authority continues to review inspection findings but has not disclosed its conclusions. These developments do not mean that all four operations face the same enforcement outcome.
For mine operators, the cases highlight several interconnected risks: expired permits, tailings infrastructure, water management, incident notification and incomplete corrective actions. They also show why companies must distinguish between a regulator’s findings, allegations that remain unresolved and a company’s account of its own response.
Earl International: A shutdown over outstanding compliance issues
The EPA ordered Earl International Mining Limited to cease operations at its underground gold mine and processing facility at Gbane in Ghana’s Upper East Region. The authority issued the closure notice on September 22 after the company failed to complete corrective measures outlined in earlier enforcement and pre-closure notices, according to the notice reported by MyJoyOnline.
The notice identified several compliance concerns. Earl’s environmental permits for its underground mine, processing plant and tailings storage facility had expired in February 2023. The EPA also cited the company’s failure to provide a required reclamation bond and its construction of facilities without the necessary approval.

The authority raised further concerns about the tailings storage facility’s engineering and monitoring arrangements, including the lack of monitoring instrumentation. It also cited incomplete cell-reclamation work and the discharge of underground water without an adequate assessment of its quality and quantity. The EPA said Earl had not completed the required corrective measures. The notice also highlighted the need to protect the concession from illegal mining activity.
Reuters described the shutdown as a legacy compliance issue linked to illegal gold-mining activity. Earl’s representative later said the company had addressed the EPA’s concerns and received clearance to resume operations, citing an environmental permit signed by the authority’s chief executive on September 28. That remains the company’s account; the available reporting does not independently verify that Earl resolved every issue in the closure notice.
The case shows how several compliance failures can converge into a serious operational problem. Expired permits, incomplete corrective actions, inadequate financial assurance and weaknesses in tailings or water controls can compound one another.

Operators therefore need more than a permit register. They must track every permit condition, regulatory directive and outstanding action, assign responsibility for each item, and retain evidence that demonstrates compliance.
Cardinal Namdini: The importance of timely incident reporting
Cardinal Namdini Mining received a pre-closure notice over an alleged failure to report a tailings-pipeline incident promptly. EPA Deputy Chief Executive for Operations Michael Ayamga told Reuters that the notice partly concerned an alleged failure to report a pipeline disconnection that resulted in a spill from a mine-waste transport system.
The procedural distinction matters. The EPA issued a pre-closure notice, not a final closure order. The available reporting does not establish a final regulatory finding on the alleged reporting failure or the spill’s full environmental impact.
For mine operators, the case highlights the need for clear incident-reporting protocols. Companies should define who must notify regulators, which events trigger notification, how quickly staff must report them and what information the notification must contain.
Internal investigations and remediation remain essential, but they do not replace regulatory reporting obligations. Operators should also maintain effective inspection, maintenance and monitoring systems for tailings pipelines. Staff must know how to escalate abnormal conditions, while incident records should capture the event, the response, regulatory notifications and follow-up actions.
The Cardinal case puts the handling and reporting of an incident alongside the physical integrity of the system itself.
Gold Fields Tarkwa: Inspection findings remain under review
The EPA is reviewing findings from an inspection of Gold Fields’ Tarkwa operation. The authority has not disclosed its findings or announced whether it will take further action. The inspection alone does not establish that the mine breached environmental requirements.
Gold Fields said it received notice on September 14 of the regulator’s intention to conduct a broad environmental, social, governance and socio-economic impact assessment at Tarkwa. The company said it had requested additional time to review the scope and obtain advice.
Gold Fields also cited its regular monitoring, independent assurance and regulatory oversight, along with its ISO 14001 environmental certification and International Cyanide Management Code certification. These are the company’s stated controls and credentials; they do not establish what the EPA found during its inspection.
The next significant development will be the authority’s findings and any decision on further action. Until the EPA discloses those findings, the Tarkwa case remains an inspection under review—not a confirmed environmental violation.
Reuters has reported that Tarkwa’s mining lease expires in 2027. That deadline matters to the operation’s longer-term planning, but the available information does not establish that the environmental inspection will determine the lease’s outcome.
Iduapriem: A tailings incident and its operational response
Reuters reported that the EPA fined AngloGold Ashanti’s Iduapriem mine in 2025 for environmental breaches. The regulator did not disclose details of the fine.
Separately, AngloGold Ashanti described an environmental incident at Iduapriem on February 17, 2025. The company said process water and related solids escaped through a tear in the liner of the Beposo tailings storage facility. It reported that the mine immediately suspended gold processing, notified the EPA and Ghana’s Minerals Commission, and completed permanent repairs after the agencies conducted inspections and sampling.
The available reporting does not establish that every detail of the company’s account relates directly to the breach that prompted the EPA’s fine. The two matters should therefore remain distinct.
The operational implications are nevertheless clear. A tailings incident can force a mine to make immediate decisions about processing, containment, regulator notification, environmental assessment and repairs. A sound response requires clear lines of authority, timely action and records that allow regulators to assess what happened and whether the company’s corrective measures addressed the problem.
Ghana’s stated shift towards proactive oversight
The EPA has said it wants to move beyond periodic inspections and one-off audits towards more proactive monitoring and enforcement. Ayamga told Reuters that the authority plans environmental, social and governance audits across the mining sector. He described the EPA’s aim as a shift from reactive intervention to proactive enforcement.
That statement outlines the regulator’s intended direction; it does not prove that the EPA already applies continuous monitoring uniformly across every mine. Still, operators should expect to demonstrate effective controls between formal inspections, rather than relying mainly on preparations for scheduled visits.
The government is also pursuing broader changes to Ghana’s mining sector, including stronger state oversight, greater local participation and increased public revenue. These objectives form part of the wider policy context, but operators should assess the environmental cases on their specific facts and regulatory status.
What mine operators should review
The recent cases offer a practical checklist for operators in Ghana and other mining jurisdictions.
- Permit management: Keep a current register of permits, expiry dates, conditions, renewals and approvals for changes to facilities or operations.
- Corrective-action tracking: Assign an owner and deadline to every regulatory directive. Retain evidence showing what the company did and when it completed the work.
- Tailings integrity: Maintain inspection, monitoring and maintenance programmes for tailings storage facilities, pipelines and associated infrastructure.
- Incident notification: Define reporting thresholds, responsibilities and timelines. Keep records of notifications, investigations and follow-up actions.
- Water management: Meet applicable discharge and water-quality requirements, and maintain reliable monitoring data.
- Reclamation and financial assurance: Keep reclamation plans and required bonds or other financial assurances current.
- Site security: Assess risks from illegal mining and unauthorised access, including their potential effects on environmental controls and operational safety.
These measures cannot guarantee that a regulator will not take enforcement action. They can help operators identify gaps earlier, respond consistently and demonstrate compliance with applicable requirements.
Compliance must be demonstrated, not simply declared
Ghana’s recent cases span several stages of regulatory action. The EPA shut down Earl International before the company reported receiving clearance to resume. Cardinal Namdini faces a pre-closure notice over an alleged reporting failure. The authority continues to review its Tarkwa inspection findings, while public reporting provides limited detail about the breaches behind Iduapriem’s earlier fine.
Operators should not treat these cases as interchangeable. Their common thread is the need for effective environmental controls and credible evidence that those controls work.
Mining companies must keep permits current, maintain tailings and water-management systems, report incidents within applicable timelines and close corrective actions with verifiable evidence. Regulators, in turn, must communicate findings clearly, verify corrective measures and apply requirements consistently.
Environmental compliance is not a document assembled when inspectors arrive. It is an operating discipline that mines must maintain throughout their lives.
