Antilles Gold Nueva Sabana copper-gold mine build starts in Cuba

Antilles Gold

Antilles Gold has begun building the Antilles Gold Nueva Sabana copper-gold mine in Cuba. The company is developing the site with state miner GeoMinera. As a result, the Antilles Gold Nueva Sabana copper-gold mine becomes a near-term Caribbean supply story.

The partners expect the Antilles Gold Nueva Sabana copper-gold mine to commission by end-2026. The project targets a four-and-a-half-year mine life. It will process ore through a 500,000 t/yr flotation concentrator. The mine is estimated at 9,150 tonnes of copper and 76,949 ounces of gold.

Commissioning timeline tightens focus on execution and logistics

The build schedule places delivery risk at the center of the project. Therefore, construction progress and equipment commissioning will drive near-term valuation. However, the short mine life also raises the importance of steady throughput.

Flotation output will produce copper and gold concentrates. Antilles Gold plans to sell the concentrates via an offtake deal. The company has not disclosed the trading counterparty. Meanwhile, this structure can de-risk marketing and cash conversion.

Offtake strategy supports cash flow and follow-on exploration

A concentrate offtake agreement can stabilize sales channels. It can also reduce exposure to spot marketing constraints. As a result, the project can prioritize ramp-up discipline over commercial negotiations.

The joint venture plans to reinvest part of free cash flow into exploration. The target is the Sierra Maestra belt in southeast Cuba. Therefore, Nueva Sabana can act as a funding engine for a broader copper pipeline. That strategy matters as global copper supply stays tight.

The Metalnomist Commentary

This project is small in global terms, but it is operationally meaningful for regional concentrates. However, the short mine life makes exploration success essential for long-term continuity. Therefore, investors will watch ramp-up metrics and drilling results in parallel.
