Cost Edge and German Backing Put EcoGraf's Graphite Ambitions on Firmer Footing

Independent assessment validates EcoGraf's HFfree purification at $478/tonne, 34% cheaper than hydrofluoric acid. Epanko project nears financing with KfW IPEX-Bank mandate of $105M. Stock up 25%.

An independent global assessment has validated what EcoGraf has been pitching for months: its proprietary HFfree graphite purification technology undercuts competing methods by a wide margin. Operating costs for a 25,000-tonne-per-year plant come in at $478 per tonne — 25% lower than the company’s own estimate from July 2024 and 34% below the next-cheapest industrial standard, hydrofluoric acid purification at $721 per tonne. High-temperature chlorination runs at $954 and ultra-high-temperature processing at $1,005.

That cost advantage is more than a technical footnote. It strengthens EcoGraf’s pitch to battery manufacturers scrambling to build supply chains outside China, and it arrives just as the company’s flagship Epanko graphite project in Tanzania moves closer to a financing decision. Shares have responded: at A$0.23 (€0.14) the stock was up 1.54% on the day and has gained 25.27% over the past seven trading sessions. The relative strength index sits near 60 — not yet overbought — though an annualised 30-day volatility above 86% serves as a reminder how quickly sentiment can shift.

Financing framework takes shape

Germany’s KfW IPEX-Bank has been mandated to structure a debt facility of up to $105 million for Epanko under the country’s UFK programme for critical raw materials. EcoGraf has already cleared the preliminary review by the German inter-ministerial commission, a step that does not constitute a final commitment but unlocks the next stage of due diligence. The environmental and social assessment, including an action plan, is complete, and the independent engineering report is in its final phase. Those documents are essential for the commission to consider a provisional approval.

Epanko is the centrepiece of EcoGraf’s strategy to supply high-purity graphite products for lithium-ion batteries to Asia, Europe and North America. First-phase output is planned at 73,000 tonnes annually, with a longer-term expansion option to 390,000 tonnes within ten years. The global graphite market is forecast to grow 8% per year from 2025 to 2035, driven by electric vehicles and stationary storage. For a small-cap miner, the timing of financing and project delivery relative to that demand curve is everything.

Grant support adds momentum

Alongside the UFK debt, EcoGraf is advancing a total of €6.2 million (roughly A$10 million) in grant funding. Part of that has already been approved by the European Investment Bank; additional applications under the DEG Impulse initiative are at an advanced stage. These funds are earmarked for development work and to prepare potential purification facilities near battery hubs.

The economics of a standalone US-based HFfree plant — without connection to Epanko ore — have also been calculated. EcoGraf estimates an investment of $95 million for a 25,000-tonne facility, generating a pre-tax net present value (NPV10) of $282 million, an internal rate of return of 42% and annual EBITDA of $42 million. The cost breakdown of the $478-per-tonne operating figure is $146 for utilities and reagents, $274 for labour and $58 for maintenance, with savings achieved through lower reagent consumption, reduced waste volumes and cheaper disposal.

Broader application in recycling

The HFfree process yields graphite with 4N purity — 99.99% carbon — using commercially available reagents that can be sourced in Europe, North America and Asia. EcoGraf has also qualified the technology for anode recycling, running test programmes with battery-market participants that confirmed its applicability to recycled anode material. That widens the addressable market beyond primary production.

The near-term catalyst remains the German commission’s provisional approval. If granted, it could lead to a binding cover commitment and push the Epanko debt facility substantially closer to reality. With the cost validation now independently confirmed, the next test is turning paper milestones into commercial-scale operations.
