Highlights

• Pensana's Longonjo Rare Earths Project in Angola has transitioned from planning to active construction.
• Main construction works are underway on budget, targeting 2027 for commissioning with a production goal of 20,000 tpa MREC.
• Critical infrastructure is complete and operational, including:
  • A Global Industry Standard tailings facility
  • A concrete batching plant
  • A 2 MW regrind mill
  • A modular sulphuric acid plant
• The project demonstrates execution discipline that is rare in African mining.
• Strategic positioning along the Lobito Corridor provides containerized rail-to-port logistics.
• Longonjo is established as a credible ex-China upstream anchor in the rare earth supply chain.
• Challenges remain in downstream separation and magnet production.

Steel is now in the ground, not just slides on a screen. That is, construction momentum at the Longonjo Rare Earths Project in Angola (opens in a new tab) marks a meaningful shift for Pensana—from capital markets storytelling to physical execution. Following Fundo Soberano de Angola (opens in a new tab) **(**FSDEA)-funded early works in 2025, the company reports that main construction is now well underway, on budget, and aligned with a 2027 commissioning target. In rare earths, where timelines often slip quietly, visible progress matters.

What stands out is not marketing language, but specifics: a tailings storage facility designed to the Global Industry Standard, a commissioned concrete batching plant, a fabricated 2 MW regrind mill, and a modular sulphuric acid plant already under construction in Brazil. These are not conceptual line items. They are irreversible steps.

The Unromantic Backbone of a Supply Chain

Rare earth independence is not won with ore bodies alone. It is won with tailings discipline, acid supply, power, water, and logistics. Longonjo’s proximity to the Lobito Corridor, with containerized rail transport to port, is strategically credible and globally relevant. Infrastructure—power, potable water, wastewater treatment, telecoms—was installed and commissioned in 2025, removing one of Africa mining’s most common execution risks. Rare Earth Exchanges™ has reported on the impressive moves Pensana has made on the ground there.

Equally important is Pensana’s modular construction philosophy, which reduces on-site complexity and schedule risk. This is not innovation hype; it is industrial pragmatism—something the rare earth sector has often lacked.

Where the Claims Hold—and Where Optimism Is Necessary

The factual backbone of the announcement is solid. Construction milestones, vendor names, and fabrication status align with known best practices and realistic sequencing. The 20,000 tpa MREC target, with expansion to 40,000 tpa, is ambitious but technically plausible given Longonjo’s grade and free-dig profile.

Where caution is warranted is in downstream ambition. The vision of a fully integrated U.S. mine-to-magnet supply chain, partnered with eVAC Magnetics and backed by the U.S. government, remains aspirational, not executed.  But impotently, the vision and deal memos are in place.  That being said, separation chemistry, magnet qualification, and sustained offtake remain the true bottlenecks—and none are trivial. And we are here to remind us all of that reality.

Why This Matters Beyond Angola

In a market dominated by Chinese refining and magnet production, Longonjo represents something rare: a credible ex-China upstream anchor paired with infrastructure realism. It does not solve the magnet problem in the short run—but it feeds the only path that can.

Pensana is not selling a shortcut. It is building a long road.
