Halifax, Nova Scotia — January 13, 2026 — Leads & Copy — Mongoose Mining Ltd. (CSE: MNG) has announced the publication of a detailed presentation outlining the technical and strategic rationale behind the Company’s refocus toward the evaluation of natural (geologic) hydrogen across its Nova Scotia land package.
The presentation, accessible on Mongoose’s website, summarizes the geological assessment work completed by management and reviewed by the Board of Directors, providing additional context regarding the data-driven basis for the refocus. The materials draw upon decades of historical geological, geophysical, and structural datasets originally generated through iron-oxide-copper-gold (“IOCG”) exploration programs.
In connection with the release of the presentation, the Company has also published a letter from its Chairman to shareholders describing the review process, governance considerations, and strategic context considered by the Board.
Matthew Allas, Chairman of Mongoose Mining Ltd., commented that the presentation is intended to provide shareholders with transparency into the technical work that informed the Board’s decision and introduce the fundamentals which underpin the value proposition identified. He noted that it reflects a reassessment of existing data through an evolving scientific framework, rather than a departure from the geological fundamentals that have long underpinned the Company’s assets.
The Chairman’s letter to shareholders provides additional context regarding the assessment work undertaken, as detailed in the Company’s recently published strategic rationale presentation. It states that over several months, a structured technical and strategic review of the Company’s Nova Scotia asset base was conducted. This review included a re-evaluation of historical geological, geophysical, and structural datasets originally generated through IOCG exploration programs.
The purpose of this process was to assess whether the Company’s existing technical foundation continued to support the most appropriate deployment of capital and effort considering evolving scientific understanding and market conditions. The review did not reflect a diminished confidence in IOCG systems, the company stated. The geological attributes that initially attracted advanced IOCG exploration to the region – radiogenic basement rocks, iron-rich lithologies, and long-lived fault systems – remain present and technically valid and continue to underpin the intrinsic geological quality of the Company’s land position, according to the company.
Through this reassessment, it was identified that these same geological characteristics are now understood to be fundamental to the generation and migration of natural (geologic) hydrogen. Advances in global research and the increasing number of drilled and tested hydrogen systems internationally provided an updated interpretive framework through which the Company’s historical subsurface data could be reviewed.
The company reports that analysis indicated that the Company’s existing drill core, structural interpretations, airborne magnetic data, gravity surveys, and alteration models exhibit material similarities to geological settings associated with confirmed hydrogen systems elsewhere. These observations are based on historical subsurface data and do not constitute confirmation of hydrogen presence or commercial viability on the Company’s properties.
In addition to internal technical work, the Board considered broader industry developments within Nova Scotia, including the entry of technically capable and well-capitalized third-party groups focused on natural hydrogen exploration. While the Company does not rely on third-party activity as a basis for its strategy, the Board considered this activity as a contextual indicator of growing interest in the regional geological framework.
Following this review, the Board evaluated strategic considerations with reference to technical probability, capital requirements, timelines to potential validation, jurisdictional considerations, and overall risk profile. Based on this process, the Board remains of the view that the Company’s strategic direction is appropriate and grounded in disciplined technical assessment.
The Company will continue to communicate material developments as required and in accordance with applicable securities laws.
Terry Coughlan, P.Geo., the Company’s Chief Executive Officer, a Qualified Person within the context of Canadian Securities Administrators’ National Instrument 43-101; Standards of Disclosure for Mineral Projects, reviewed and approved the scientific and technical information contained in this news release.
