Patagonia Lithium (ASX:PL3) Surges 53% on Ameerex Partnership: Is This Lithium Explorer a Buy?

Patagonia Lithium Secures Key Partnerships for Growth

Patagonia Lithium (ASX: PL3) surged 53% to A$0.13 on Friday, hitting its highest level in nearly a year after announcing a strategic partnership with US-listed Ameerex Corporation. The deal positions Ameerex to invest in Patagonia’s flagship Formentera lithium project in Argentina, as well as its niobium and rare earth assets in Brazil.

With a market cap of around A$23 million, Patagonia Lithium remains a small-cap explorer. But the Ameerex deal comes just weeks after the company raised A$2.68 million, giving it two sources of capital to push forward with drilling and development work. For investors watching the lithium space, the question is whether this partnership changes the risk profile enough to justify buying at current levels.

Ameerex Deal Opens Door to Project-Level Funding

The Ameerex partnership is non-binding at this stage, but the terms are interesting. Ameerex can invest at both the company level and directly into individual projects, with the option to take up to 50% of project value in mining ventures. The US-based company has a management team in Doha and a strategy focused on co-investing in lithium explorers.

For Patagonia Lithium, this deal matters because it provides a potential funding path that does not rely solely on share placements. Traditional equity raises at this stage often come with steep discounts and heavy dilution. Having a strategic partner willing to invest at the project level could help Patagonia advance its Formentera project without crushing existing shareholders.

Executive Chairman Phillip Thomas noted the partnership adds another source of capital as the company works towards key milestones, including a substantial indicated resource and a scoping study. The company is currently drilling its fifth well at Formentera, recently reaching 335 metres on its way to a 400-600 metre target.

Formentera Project Shows Promising Early Results

The Formentera project sits in Argentina’s Lithium Triangle, one of the world’s most important lithium-producing regions. The project already has a JORC-compliant resource of 551,000 tonnes of lithium carbonate equivalent as drainable brine, plus a larger inferred resource of 3.8 million tonnes across the broader project area.

What makes Formentera attractive is the early pilot testing results. Using Ekosolve’s direct lithium extraction technology, the company achieved recovery rates of around 92% from its brines. This is a strong result that reduces technical risk and supports a faster development timeline compared to traditional evaporation-based lithium projects.

Patagonia Lithium has outlined a staged development plan starting with a 1,000 tonne per year demonstration plant, followed by expansion to commercial-scale production of around 10,000 tonnes per year. At current lithium prices, commercial-scale production could generate revenues approaching US$100 million annually, though this remains years away.

The Investor’s Takeaway

The bull case for Patagonia Lithium rests on three factors: the Ameerex partnership reduces funding risk, the Formentera resource is already JORC-compliant, and the DLE pilot results look promising. Argentina’s mining-friendly reforms add further appeal.

However, this remains a speculative opportunity. The Ameerex deal is non-binding, commercial production is years away, and lithium prices remain volatile. The company is pre-revenue and still proving up its resources.

Patagonia Lithium has improved its position with this partnership. For investors comfortable with high-risk explorers, the stock offers leverage to a lithium recovery. But position sizing should be small, and investors should watch for resource upgrades and scoping study results as key milestones.
