Edison Lithium Names Andrew Gainsbury as CFO and Director; Mourns Loss of Director Jay Richardson

Andrew Gainsbury Confirmed as Permanent CFO Following Interim Service

Edison Lithium has formalized Andrew Gainsbury’s role as Chief Financial Officer and Director, effective July 23, 2026, subject to TSX Venture Exchange approval. Gainsbury has served as interim CFO since March 1, 2026, and previously held the Controller position, ensuring stable financial leadership during the transition period.

With over 16 years of expertise in financial management and consulting across Canada and Brazil, Gainsbury’s background includes CFO roles at publicly listed junior mining companies and Controller positions. He formerly served as CFO of a Brazilian engineering firm with more than 800 employees and as a senior consultant at Deloitte Brazil, leading corporate finance projects across various industries. His credentials include an MBA from McGill University, along with CFA and CPA designations, highlighting his strong financial acumen.

Honoring the Legacy of Director James "Jay" Richardson

Edison Lithium announced the passing of James "Jay" Richardson, who had been a Director since February 2, 2021, and served as CFO until March 1, 2026. Richardson stepped down from the CFO role due to illness and was succeeded by Andrew Gainsbury on an interim basis. The company and board extended deepest sympathies to Richardson’s family, friends, and colleagues.

Richardson’s valuable contributions and leadership during his tenure were recognized, with the company noting he will be fondly remembered. The appointment of Gainsbury as interim CFO in March 2026 corresponded with Richardson’s health challenges, and Gainsbury’s permanent appointment in July 2026 concludes the interim period.

Progress on Property Option Agreement with Globex Mining Enterprises

Edison Lithium updated on its property option agreement with Globex Mining Enterprises Inc., effective February 27, 2026. Under this agreement, Edison Lithium may earn a 100% interest in the Joutel North-West gold property and the Gagne gold-copper property (together the "Properties"), subject to a 3% Gross Metal Royalty retained by Globex. The company also holds a right of first refusal to acquire all or part of the royalty on terms matching any bona fide third-party offer.

The transaction remains conditional on several factors, including completion of a National Instrument 43-101 compliant technical report and final TSX Venture Exchange acceptance. Steven Lauzier, P.Geo. OGQ1430, was engaged to prepare an independent NI 43-101 technical report, which is currently under company review pending finalization.

Independent Site Visit and Technical Report Preparation

As part of the NI 43-101 report preparation, an independent site visit to the Properties and drill core storage location from Orford Mining’s 2022–2023 work took place between May 18 and May 20, 2026. Steven Lauzier conducted the site assessment, accompanied by Roger Dahn, P.Geo. and Edison Lithium Director, who verified the drill core locations. Photographs included in the announcement document illustrate the core storage facility and specific drill hole intersections from prior exploration.

This site visit was crucial for validating exploration data and geological context before finalizing the technical report. Confirmation of drill core materials from Orford Mining’s recent campaign, especially from the South Gold Zone, supports the historical assay results and intersection data disclosed by the company.

Geological Overview and Historical Exploration of Joutel and Gagne Properties

The Joutel North-West and Gagne properties lie along the South Break of the Casa Berardi Structural zone, near several former producing mines. Notably, the Eagle–Telbel–Eagle West deposits, approximately 3 km east and operated by Agnico Eagle, produced about 1.1 million ounces of gold from 6.2 million tonnes grading 5.8 g/t gold before closing in 1993. The gold-bearing structural sequence extends over 11 km across the Joutel North-West property, including the South Gold Zone, which has been the focus of recent exploration.

The proximity to historically productive gold mines with documented mineralization underpins the geological rationale for exploration. The continuity of host structures across the Joutel North-West property provides a framework for interpreting recent drilling results by Orford Mining.

Orford Mining’s 2022–2023 Drilling Highlights at South Gold Zone

Orford Mining’s drilling on the Joutel North-West property during 2022–2023 targeted the South Gold Zone. The company reported multiple drill-hole intersections on a drilled-width basis, not converted to true widths.

Key intersections include: hole 23-JE-004 with 30.1 metres at 1.1 g/t gold from 128.8 metres downhole; hole 23-JE-015 with 54.7 metres at 1.1 g/t gold from 81.1 metres; hole 22-JE-003 with 20.64 metres at 1.11 g/t gold from 84.83 metres, including 0.64 metres at 14.7 g/t gold; and hole 23-JE-008 with 15.7 metres at 1.7 g/t gold from 21.7 metres and 14.2 metres at 2.2 g/t gold from 61.9 metres. Site photographs numbered 1, 2, and 3 visually confirm core from these intersections, taken during the May 2026 site visit.

Edison Lithium’s Strategic Focus on Battery Metals and Exploration Assets

Edison Lithium is a Canadian junior mining exploration company focused on acquiring, exploring, and developing cobalt, lithium, alkali, and other energy metal properties. The company targets affordable, high-quality mineral properties in geologically prospective regions to build a portfolio supplying critical battery materials. This positions Edison Lithium to capitalize on growing demand in the battery metals sector.

The addition of the Joutel North-West and Gagne properties complements the company’s portfolio by targeting gold mineralization in a district with a documented production history and active exploration, aligning with Edison Lithium’s strategy of acquiring mineral assets in proven exploration districts.

Pending Regulatory and Transactional Conditions

The property option agreement with Globex Mining remains subject to conditions including completion of the NI 43-101 technical report and final TSX Venture Exchange approval. As of the announcement, the technical report was under company review prior to finalization by the qualified person.

The company has not disclosed specific timelines for satisfying these conditions or receiving final exchange acceptance. Investors should watch for future updates on progress toward these milestones and the transaction’s completion.

Forward-Looking Statements and Associated Risks

The announcement contains forward-looking statements regarding the proposed acquisition, satisfaction of agreement conditions, technical report completion, payments, share issuances, planned financing, expenditures, and regulatory approvals including TSX Venture Exchange acceptance. These statements are based on management’s current assumptions and involve risks and uncertainties.

Risks include the possibility that the transaction may not close, conditions may remain unmet, the agreement could be terminated, or exchange acceptance may be withheld. Additional risks involve financing availability, mineral exploration uncertainties, geological interpretation, title and access issues, permitting, environmental factors, commodity prices, currency fluctuations, capital markets conditions, contractors, weather, and natural events. The Properties are at an early exploration stage, and Edison Lithium has not confirmed commercial mineralization. References to potential or prospectivity are speculative and may not be realized, and mineralization on nearby properties does not guarantee similar results on these Properties.
