Cuba holds 5.5% of global nickel reserves — concentrated in the Moa-Nicaro mining belt just 80 kilometers from Antilla Bay. Despite this extraordinary geological asset, no modern deepwater export terminal connects this resource to the global supply chains it could serve. As the world's energy transition accelerates demand for nickel and cobalt, the gap between Cuba's mineral wealth and its export infrastructure becomes one of the most consequential infrastructure deficits in the Western Hemisphere.

This is not a hypothetical future opportunity. Cuban nickel operations have been running continuously since the 1940s. The reserves are proven, the processing technology is established, and a Canadian company has sustained profitable operations here for over 30 years — even under U.S. sanctions pressure. What's missing is the port. Here's the full picture.

The Moa-Nicaro mining belt stretches roughly 200 kilometers along Cuba's northern coastline in Holguín province. It hosts one of the highest-grade lateritic nickel-cobalt deposits in the world — a geological formation created over millions of years as tropical weathering concentrated nickel and cobalt from underlying ultramafic rock. The result is ore that yields both nickel and cobalt in a single extraction process, making it a rare dual-mineral asset at a moment when both materials are in surging global demand.

Cuba's share of global nickel reserves — approximately 5.5% — places it alongside major producers like the Philippines and Australia. But unlike those countries, Cuba has barely scratched its reserve base. Current annual production at the Moa Bay operation runs around 33,000 tonnes of nickel and 3,300 tonnes of cobalt. For reference, Indonesia, which has aggressively expanded its nickel output in recent years, now produces over 1.5 million tonnes annually. The gap between Cuba's reserve position and its actual output reflects infrastructure constraints, not geological limits.

The ore at Moa is processed using High-Pressure Acid Leach (HPAL) technology — the same process that Indonesia's major operators use. This produces a mixed nickel-cobalt sulfide intermediate, which is then shipped to a refinery in Fort Saskatchewan, Alberta, Canada, for conversion to battery-grade nickel and cobalt sulfate. The two-step geography — Cuba extraction, Canadian refining — is a consequence of historical relationships and the absence of on-site processing infrastructure, not technological necessity.

What makes the geology of Moa particularly significant for the energy transition is the cobalt co-production. Most nickel deposits yield little or no cobalt. Moa's lateritic ore produces economically significant cobalt alongside every tonne of nickel extracted — a natural hedge against the volatility in cobalt supply that has plagued battery manufacturers dependent on the Democratic Republic of Congo.

Any serious analysis of Cuba's natural resources opportunity must grapple with Sherritt International , the Toronto-listed mining company that has operated the Moa Joint Venture since 1994. Sherritt's Cuban operation is a 50-50 partnership with Cubaniquel, Cuba's state nickel company. It is the longest-running foreign mining investment on the island — and one of the most unusual corporate stories in the global mining industry.

Sherritt has maintained Cuban operations through multiple commodity cycles, through the collapse of the Soviet-era subsidies that had propped up Cuba's economy, through the tightening of U.S. sanctions under successive administrations, and through significant financial pressure on its own balance sheet. Its executives are barred from entering the United States as a consequence of their Cuban business dealings. Its banking relationships are complicated by sanctions exposure. And yet the company has not walked away from the Moa deposit.

That persistence is meaningful data. It tells you that the economics of the Moa deposit — even burdened with sanctions overhead, logistical inefficiency, and the political complexity of operating in Cuba — are favorable enough to justify 30+ years of commitment from a public company with shareholder accountability. Strip away those overheads with better infrastructure and a normalized political environment, and the asset becomes dramatically more attractive.

Sherritt's current operational model — mine and partially process in Cuba, refine in Canada — is the direct result of Cuba lacking a port-adjacent refinery. If refined nickel sulfate and cobalt sulfate could be produced at source and loaded directly onto a Panamax vessel at Antilla Bay, the entire logistics chain shortens by thousands of nautical miles. The value capture shifts from Canadian and intermediary hands to Cuban operations. This is not a marginal improvement — it is a structural change in the economics of the deposit.

The global electric vehicle industry needs extraordinary amounts of nickel and cobalt — and it needs them from sources that Western manufacturers can actually use. A single 75 kWh EV battery pack contains approximately 8-10 kg of nickel and up to 2 kg of cobalt. Global EV sales are projected to exceed 50 million units annually by 2030. The math is unforgiving: current supply chains cannot come close to meeting that demand, particularly for manufacturers in the United States and European Union who are under regulatory pressure to source critical minerals from friendly-nation suppliers.

Indonesia currently dominates global nickel supply growth — but the overwhelming majority of new Indonesian nickel capacity has been built and financed by Chinese companies, processing ore into battery materials that flow primarily into Chinese battery supply chains. For U.S. and EU automakers trying to comply with the Inflation Reduction Act's critical minerals provisions, Indonesian nickel processed by Chinese-owned facilities is problematic. They need Western Hemisphere or allied-nation alternatives, and they need them at scale.

Cuba's position in this landscape is genuinely strategic. It sits 90 miles from Florida — closer to the U.S. coastline than any other significant nickel-cobalt source. Its reserves are proven and substantial. Its processing technology is established. And its deposits produce both of the most critical battery cathode inputs — nickel and cobalt — from a single mining operation. The missing link is not geological, not technological, and arguably not even political in the long run. It is infrastructural. A deepwater export terminal at Antilla Bay, combined with refining capacity at source, would connect Moa's proven reserves directly to the supply chain that the global energy transition is desperate to fill.

While Moa dominates current Cuban nickel production, Nicaro, Cuba — located 40 kilometers west along the coast — represents a separate chapter in the mineral story with significant implications for future scale. Nicaro was the site of a U.S. government-operated nickel plant during World War II, activated to supply the war effort when global supply chains were disrupted. At its peak, the Nicaro facility was the largest single nickel processing operation in the Western Hemisphere.

After the Cuban Revolution, Nicaro continued operating under nationalized management with Soviet technical support. As Soviet subsidies collapsed in the early 1990s, the Nicaro operation deteriorated and has been largely dormant for decades. The historical infrastructure is in poor condition. But the ore body that justified building one of the hemisphere's largest nickel plants still exists. Any significant expansion of Cuba's mineral output would almost certainly involve Nicaro's revival alongside Moa's growth.

The geography of a full Moa-Nicaro corridor is striking: two major mining complexes, 40 kilometers apart, with Antilla Bay sitting approximately 80 kilometers west of Moa. A rail and road mineral corridor connecting Moa, Nicaro, and Antilla Bay would create a linear industrial zone along Cuba's northern coast — mining, processing, and export infrastructure across a 200-kilometer stretch. This is precisely the model that Indonesia's North Maluku nickel corridor demonstrates is achievable with coordinated infrastructure investment and clear policy frameworks.

The current export pathway for Cuban nickel illustrates exactly why infrastructure placement matters. Mixed nickel-cobalt sulfide from Moa loads onto a vessel at Moa port — a shallow-water facility with limited vessel capacity — and travels approximately 4,200 nautical miles to a European transshipment point before reaching the Fort Saskatchewan refinery in Alberta for final processing. From there, battery-grade nickel sulfate ships to cathode manufacturers in South Korea or Japan. The full logistics chain stretches over 12,000 nautical miles before Cuban ore becomes a battery material.

A deepwater bulk terminal at Antilla Bay, paired with on-site HPAL refining capacity, would collapse this chain dramatically. Refined battery-grade nickel sulfate and cobalt sulfate, produced at source, loads directly at Antilla Bay onto a Panamax vessel and ships approximately 8,500 nautical miles direct to a South Korean battery manufacturer — or far less to a U.S. Gulf Coast operation under a future IRA-compliant supply agreement. Conservative estimates put the freight cost reduction at 35–50% per tonne of finished product. The value retained in Cuba — rather than captured by intermediary refiners — grows correspondingly.

This is the core of the Antilla Bay minerals opportunity: it is not simply a port. It is the infrastructure that transforms a world-class but constrained mining operation into a vertically integrated critical minerals export complex. The sequence is mine expansion at Moa → on-site HPAL refining → deepwater bulk export at Antilla Bay → battery precursor manufacturing in an Antilla SEZ. Each stage builds on the last. The port is the enabling infrastructure for the entire chain.

Cuba's nickel and cobalt resources are not a speculative bet. They are proven, operating assets with a 30-year track record of profitable extraction under some of the most challenging conditions any mining company faces anywhere in the world. The Moa-Nicaro belt holds reserves that, if properly connected to global markets, could make Cuba a significant supplier to the Western Hemisphere's energy transition supply chain — reducing dependence on Chinese-controlled Indonesian operations and DRC cobalt simultaneously.

The single biggest constraint is not political, not geological, and not technological. It is the absence of a modern deepwater export terminal 80 kilometers west of the mines. Antilla Bay is where that constraint gets resolved — and where Cuba's natural resources take their rightful place in the global critical minerals conversation.

For investors, policymakers, and supply chain architects tracking the energy transition, the mineral corridor from Moa to Antilla Bay represents one of the most compelling underdeveloped infrastructure opportunities in the Caribbean basin. The question is not whether this opportunity is real. The question is who moves first to build the infrastructure that captures it.
