How Has the Legal Dispute Affected Blasting Operations?

The resumption of blasting operations at Loulo-Gounkoto follows a complex legal standoff between Barrick Mining and Mali's military-led government. This dispute has significantly impacted mining activities and created uncertainty about the mine's future operational status.

Timeline of Operational Disruptions

The dispute has caused substantial disruption to normal mining operations:

• January 2025: Initial suspension of mining operations following disagreements over Mali's new mining code, which proposed increased taxes and greater state ownership of mining assets.

• June 2025: Court appointment of a provisional administration led by former Health Minister Soumana Makadji to oversee operations.

• June-October 2025: Activities were limited to processing existing ore stockpiles, with no new ore extraction occurring.

• October 15, 2025: Scheduled resumption of underground blasting operations, marking a potential turning point for the mine.

Financial Impact of Operational Pause

The operational suspension has had far-reaching economic consequences:

• Production Limitations: Approximately 1.07 tonnes of gold were produced from existing stockpiles during the suspension period, significantly below normal production rates.

• National Economic Effect: Mali's industrial gold production decreased by 32% year-on-year to 26.2 tonnes by August 2025, according to documents from the mines ministry.

• Revenue Implications: The disruption caused significant reduction in both corporate profits and government tax receipts, affecting multiple stakeholders.

• Subcontractor Challenges: The dispute created payment delays affecting key service providers, including Sandvik and Maxam, whose services are essential for blasting operations.
