US Treasury Designates Cuban JV as Specially Designated National

US Sanctions Freeze Cuban Joint Venture Operations

Antilles Gold Limited (ASX:AAU) has been forced to suspend its direct involvement in the Cuban joint venture mining company Minera La Victoria S.A (MLV) after the US Treasury’s Office of Foreign Assets Control (OFAC) designated MLV as a Specially Designated National (SDN) on 4 June 2026. This sanction targets entities operating in Cuba’s metals and mining sector, effectively restricting MLV’s ability to engage with US persons or entities.

Through its subsidiary Antilles Gold Inc (AGI), the company holds a 50% interest in MLV, with the Cuban government’s GeoMinera S.A. owning the other half. Following the sanction, AGI has suspended its direct participation in MLV’s management, administration, and funding, though it retains its equity stake. This move reflects a cautious approach to comply with US sanctions while maintaining an interest in the venture.

Nueva Sabana Mine Construction on Hold Amid Regulatory Uncertainty

The sanction has also brought construction activities at the Nueva Sabana copper-gold mine to a standstill. Xinhai Mining, the contractor responsible for the Engineering, Procurement, and Construction (EPC) of the project, has suspended its work pending either removal of the designation or issuance of an OFAC licence permitting transactions with US entities. Nueva Sabana, which had been progressing towards first gold concentrate production targeted for early 2027, now faces an uncertain timeline.

This disruption comes after Antilles Gold had secured a $35 million funding package and awarded a $29.5 million EPC contract to Xinhai Mining earlier in the year, signalling strong momentum in mine development. The current suspension underscores the operational risks posed by geopolitical and regulatory factors beyond the company’s control.

Engagement with US Authorities and Market Communication

Antilles Gold has initiated discussions with the US Department of State to explore potential resolutions, though the outcome remains uncertain. The company has committed to full compliance with US sanctions and has informed its Cuban joint venture partner, Gold Caribbean Mining S.A., of the suspension of AGI’s direct involvement. Market participants can expect ongoing updates as the situation develops.

The company expressed regret over the impact of the sanction on shareholders but emphasised its proactive stance in addressing the issue. The evolving regulatory landscape will be a critical factor influencing Antilles Gold’s operational and financial prospects in Cuba.
