Pilot Plant Collaboration Raises Stakes for Neometals’ Lithium Commercialisation

A Strategic Partnership in Lithium Processing

Neometals Ltd (ASX, NMT), together with Mineral Resources Limited (ASX, MIN), has taken a significant step forward in lithium processing innovation through their joint venture Reed Advanced Materials (RAM). RAM has entered a three-year collaboration agreement with Italian electrochemical technology leader Industrie De Nora and its Japanese subsidiary De Nora Permelec. This partnership aims to combine De Nora’s cutting-edge electrolysis technology with Neometals’ patented ELi Process™ to produce battery-grade lithium hydroxide or carbonate from lithium chloride brines.

Pilot Plant Integration and Technology Advancement

The collaboration focuses on designing, building, and commissioning a pilot plant that integrates De Nora’s electrolysis equipment, known as the DN System, with RAM’s ELi Process™. This integration is expected to elevate the technology readiness level from 6 to 7, marking a transition from prototype demonstration to pilot-scale validation. The pilot plant will operate continuously at an end-user site, with Argentina identified as the likely location, subject to Rio Tinto’s approval.

Under the agreement, De Nora will supply the electrolysis stack and associated systems, while RAM will oversee brine purification, lithium hydroxide crystallisation, and overall plant control. Both parties will maintain ownership of their existing intellectual property, with new developments owned by the responsible party, ensuring clear IP boundaries and collaboration efficiency.

Implications for Sustainable Lithium Supply

This partnership aligns with broader industry trends towards sustainable and low-carbon lithium production. De Nora’s electrochemical expertise, particularly its Cechlo electrolysis solutions, complements Neometals’ focus on low-cost, environmentally responsible processing technologies. Luca Buonerba, De Nora’s Chief Marketing and Business Development Officer, highlighted the collaboration’s role in refining lithium resources sustainably, reducing environmental impact, and supporting decarbonisation efforts.

RAM Director Christopher Reed emphasised the importance of this alliance in maturing the ELi Process™ to commercial readiness, setting the stage for future commercial plants. The collaboration also establishes a steering committee to oversee engineering, testing, and development, ensuring rigorous project governance.

Looking Ahead, Commercial Prospects and Market Positioning

Subject to successful pilot operations, RAM and De Nora plan to negotiate pathways for commercial-scale deployment. This could see De Nora become the preferred supplier of electrolysis equipment for ELi Process™ plants, while RAM may recommend De Nora to its customers, fostering a mutually beneficial commercial relationship. The pilot plant’s progress and Rio Tinto’s approval will be critical milestones to watch as the project advances.

Neometals continues to develop its portfolio of sustainable processing solutions alongside its mining projects, including the Barrambie Gold Project and titanium-vanadium assets. This collaboration marks a pivotal moment in the company’s lithium chemicals strategy, potentially accelerating its role in the global battery materials supply chain.
