Element One (EHCMF) sent Twin Sisters olivine sand to Revora Materials for mineral-recovery testing after assays reached 28.46% magnesium. Eight selected samples returned 26.39% to 28.46% magnesium and 2,660 to 3,305 parts per million nickel; the assays were announced September 22, 2026. A memorandum of understanding with Millbank Materials gives Element One the right to purchase up to 50,000 tonnes of material annually, with an option to increase that amount to 100,000 tonnes.
Revora will assess mineral recovery, product purity and processing costs. The samples may not represent all Twin Sisters material. No mineral resource, recovery rate or commercially viable operation has been established, and no decision has been made to build a pilot or commercial facility.
Element One also proposes to lower the exercise price of 3,000,000 warrants from $0.25 to $0.15 per share, subject to CSE acceptance. An additional 200,000 units priced at $0.10 each are to be issued September 25, 2026.
Element One Hydrogen & Critical Minerals (EHCMF) reported assay results from eight olivine samples at the Twin Sisters ultramafic project in Washington State.
The samples showed magnesium grades between 26.39% and 28.46% Mg and nickel values between 2,660 and 3,305 ppm Ni, indicating a consistent, magnesium‑rich feedstock with meaningful nickel content. Under a memorandum of understanding with Millbank Materials, the company may purchase up to 50,000 tonnes per year of this material, with an option to increase to 100,000 tonnes per year.
Sample splits have been sent to Revora Materials for independent characterization using its IonMet™ technology, while work with Columbia University will assess the material’s natural hydrogen potential. The company notes that no mineral resource, reserve, or economic viability has yet been established, and no pilot or commercial facility decision has been made.
Element One Hydrogen & Critical Minerals (EHCMF) has signed a non-binding letter of intent with France-based Mantle8 to evaluate and advance natural hydrogen exploration opportunities in Western Canada, initially in British Columbia and Alberta.
The collaboration is intended to combine Mantle8’s proprietary exploration technologies (including GeoLogix®, HOREX® and APoGeH®) with Element One’s regional operating capabilities, permitting experience and stakeholder relationships. The parties plan to identify and rank natural hydrogen targets, assess land-acquisition options and negotiate a definitive joint venture covering ownership, funding, governance, earn-in and commercialization terms. The LOI sets a 120-day exclusivity period, automatically extendable by 60 days, plus a two-year right of first refusal on targets identified under the LOI. Except for clauses such as exclusivity and confidentiality, the LOI is non-binding and there is no assurance a definitive agreement or commercial operations will follow.
Element One Hydrogen & Critical Minerals (EHCMF) outlined a dual-pathway strategy for natural hydrogen and upsized a previously announced financing. The company is pursuing exploration for naturally accumulated hydrogen using subsurface techniques similar to oil and gas drilling, and technology to stimulate hydrogen generation from iron-rich hard rock via accelerated water-rock reactions. Partnerships with Stone to H2 and Columbia University support research into hydrogen stimulation and co-recovery of critical minerals such as magnesium and nickel.
The LIFE private placement has been increased to 7.0 million units at $0.10 per unit, each with one common share and a $0.20 warrant exercisable for 36 months, with a first tranche of 3,500,000 units closed.
Element One Hydrogen & Critical Minerals (CSE: EONE, OTC: EHCMF) reports six‑month progress on building an integrated North American natural hydrogen and critical‑minerals platform and outlines multiple development catalysts for the next three to six months.
The company entered memoranda of understanding with Twin Sisters Olivine for domestic olivine feedstock and a potential Washington State site for a scalable demonstration facility initially designed to process about 50,000 tonnes of feedstock annually, with conceptual expansion to 100,000 tonnes, all subject to validation, financing, permitting and definitive agreements. A second MOU with Revora Materials targets applying IonMet electrochemical extraction to olivine to produce high‑purity magnesium compounds and potentially magnesium metal.
Element One also holds exclusive rights to Columbia University‑led subsurface hydrogen‑stimulation technology and is advancing natural hydrogen projects in British Columbia and Alaska, while planning pilot test design, demonstration‑facility engineering, government‑funding applications and a broadened investor‑awareness campaign, including pursuing an OTCQB quotation.
