Neometals (ASX:NMT) — Primobius Positions NMT in Circular EV Supply Chain?

Q1. What is Primobius and how does it process end-of-life batteries?

Primobius GmbH is a 50/50 joint venture between Neometals and SMS Group of Germany. It has developed a proprietary two-stage battery recycling process: first, a mechanical shredding and separation stage that safely disassembles batteries and separates black mass (the active battery material containing lithium, nickel, cobalt, and manganese) from other components (steel, copper, aluminium); and second, a hydrometallurgical processing stage that dissolves the black mass in acid and selectively recovers each metal as a high-purity compound suitable for direct reuse in new battery cathode manufacturing. The process is designed to achieve high recovery rates for all four key battery metals — a commercial advantage over recycling approaches that prioritise only one or two metals.

Q2. Why is the European market specifically attractive for battery recycling? Europe has the world's most stringent and most rapidly escalating battery recycling regulatory regime. The EU Battery Regulation imposes mandatory collection and recycling obligations on battery manufacturers and importers, with minimum recovery efficiency targets and increasing recycled content requirements from 2027. This creates both a mandatory feedstock supply (batteries must be collected and processed) and a mandatory demand channel (battery manufacturers must demonstrate recycled content compliance). No other major market currently has regulations of comparable specificity and enforcement timeline. Primobius, operating in Germany, is positioned within this regulatory environment and can serve European OEMs and battery manufacturers with a regulatory-compliant recycling solution.

Q3. What is the feedstock challenge for battery recycling, and how does it affect Neometals' timeline? Battery recycling businesses require a reliable and growing supply of end-of-life batteries to process. The European EV fleet has been growing rapidly since approximately 2019–2020, but typical EV battery lifespans of 8–12 years mean that a significant volume of end-of-life batteries from this fleet will not reach the recycling market in large volumes until approximately 2027–2032. In the near term, recyclers like Primobius will supplement end-of-life batteries with manufacturing scrap — off-spec batteries, electrode trim waste, and damaged cells from gigafactories. This feedstock is available now and growing, but in smaller volumes than a fully scaled recycling facility would ultimately require. The feedstock constraint is a timing issue rather than a fundamental structural one — volumes will grow predictably as the EV fleet ages.

Q4. How does Neometals' technology approach compare to competing battery recycling technologies? The battery recycling technology landscape includes several competing approaches: pyrometallurgy (high-temperature smelting, used by Umicore) which is well-proven but energy-intensive and loses lithium; direct recycling (relithiation of cathode particles) which is still largely at laboratory scale; and hydrometallurgy (Primobius's approach) which offers high recovery rates for all four key metals but requires capital-intensive processing equipment. Primobius's competitive advantage is the combination of the SMS Group's industrial engineering and manufacturing experience, which provides construction and scale-up capability that purely technology-focused competitors may lack, with a proven hydrometallurgical recovery process demonstrated at pilot scale.

Q5. What financial milestones should Neometals investors track over the next 12–24 months? The most important financial milestones for NMT investors to monitor are: (1) announcement of binding commercial-scale offtake agreements for Primobius's recycled battery materials, which would provide revenue visibility and validate the commercial pricing assumptions; (2) confirmation of committed project financing for the expansion from demonstration-scale to full commercial-scale processing capacity; (3) quarterly operational updates from Primobius demonstrating improving processing volumes, recovery rates, and cost-per-tonne trends at the current demonstration facility; and (4) any announcement of strategic partnership interest from a major battery manufacturer, automotive OEM, or industrial recycler, which would provide both commercial validation and potentially non-dilutive financing.
