AEF Commences Stage 3 Testwork Program
Targeting Battery-Grade High-Purity
Manganese Sulphate Production
Advanced purification trials with Australia's national science agency, CSIRO, to validate
continuous operation and optimize flowsheet performance for manganese sulphate
production.
Data-driven development approach designed to generate operational and product-quality
data, reducing technical risk before major capital decisions.
Integrated development path incorporating technical, environmental and engineering
workstreams in front of a planned H1:2027 PFS.
Parallel efforts focus on producing representative manganese sulphate samples to
initiate strategic partnerships to secure offtake and funding ahead of full feasibility.
Vancouver, British Columbia--(Newsfile Corp. - February 17, 2026) -
AE Fuels Corporation
(TSXV:
AEF) ("
AEF
" or the "
Company
") is pleased to announce that its Australian subsidiary, Advanced
Energy Fuels (Aust) Pty Ltd ("
Advanced
") has signed a Stage 3 research agreement with Australia's
national science agency, CSIRO, to undertake testwork aimed at progressing a scalable purification
pathway for battery-grade, high-purity manganese sulphate monohydrate ("
HPMSM
") with optionality for
electrolytic manganese metal ("
EMM
") capability.
Gary Lewis, Chief Executive Officer and Director of the Company said: "
This program reflects our
collective desire to make smart decisions based on quality data to accelerate progress and reduce
risk. Co-funded through CSIRO's Kick-Start program, Stage 3 builds on CSIRO's world-class research
to deliver the data and know-how required for scale-up. Our goal remains a fully integrated global
manganese supply chain, from mine to battery-grade manganese sulphate. AEF is executing in
disciplined stages, validating each step and de-risking before committing major capital whilst
simultaneously securing commercial and government support. We are excited to be continuing our
collaboration with CSIRO, working together to better understand these high-purity battery materials
and to unlock their value."
The South Woodie Woodie Manganese Project
The South Woodie Woodie Manganese Project is a fully integrated HPMSM / EMM project designed to
meet multiple and evolving specifications of both Electric Vehicle and Energy Storage System markets.
To that end AEF continues to advance a staged development plan, targeting the extraction, processing
and sales of HPMSM and EMM to North American and allied markets.

The manganese deposit is located in the Eastern Pilbara region of Western Australia, and AEF recently
finalized the acquisition with the exercise of its option with Trek Metals (January 13, 2026).
Work Program
Work programs supporting the development of South Woodie Woodie commenced in 2024. Given the
broad usage of manganese within the lithium-ion battery market the challenge is to produce a high purity
product suitable for both nickel cobalt (NC) and non-NC cathodes across both mobile and stationary
energy storage markets.
In 2025, AEF partnered with CSIRO leveraging its extensive manganese testwork capability to
accelerate development. Synthetic feed solutions based on South Woodie Woodie Project chemistry
validated a conceptual flowsheet designed to produce battery-grade HPMSM, with EMM as a potential
downstream product pathway. This process will continue to add certainty to flowsheet design, with a
target of delivering a Pre-Feasibility Study (PFS) by mid-2027.

AEF is progressing a staged development pathway from feed upgrading to downstream processing,
including:
Beneficiation studies
in multiple rounds to support concentrate production assumptions.
Reduction and leaching testwork
to improve upstream performance ahead of purification.
CSIRO purification programs
providing the foundation for advanced pilot testwork.
An
internal mine planning review
has been completed to help frame potential mining scenarios
and prioritize key sensitivities for future engineering work.

Processing Pathway
AEF has commenced evaluation of a manganese processing flowsheet intended to guide ongoing
metallurgical testwork and future technical studies. The indicative flowsheet, shown below, outlines a
potential end-to-end processing pathway from run-of-mine material through beneficiation and
downstream hydrometallurgical processing, with production of high-purity manganese sulphate
monohydrate (HPMSM), and electrolytic manganese metal (EMM).

Targeting Battery Grade HPMSM - Commencing Final Stage Mn Solvent Extraction (SX)
Testwork
The next phase of testwork (Stage 3) builds on CSIRO's completed bench and pilot work and is
designed to demonstrate and optimise continuous solvent extraction (SX) purification performance; and
demonstrate first production of HPMSM meeting commercial specifications. EMM remains a potential
downstream product pathway, subject to future technical and commercial evaluation.
Timeline
AEF is pursuing a staged project execution pathway, with each stage intended to progressively reduce
technical, environmental, and commercial risk on the path to first production.
