Forward-Looking Information

This website contains "forward-looking information" and "forward-looking statements" within the meaning of applicable Canadian and other securities laws (collectively, "forward-looking information"). All statements that are not statements of historical fact are forward-looking information, including, without limitation, statements regarding the Company's strategy, objectives, plans, and future operations; the 300M+ lb antimony target; potential mineralization, resource delineation, or expansion; exploration, drilling, sampling, geophysical interpretation, metallurgical testing, permitting, and community engagement activities; the timing and scope of current and future work programs; direct-shipping ore potential; the evaluation of strategic partnerships, processing, offtake, or development arrangements; financing plans and the use of proceeds; anticipated catalysts, milestones, and market developments; the potential impact of antimony prices, policy developments, and broader supply-chain trends; and the project's potential to become a secure North American antimony source. Forward-looking information is often, but not always, identified by words such as "may," "will," "expect," "anticipate," "intend," "plan," "estimate," "potential," "target," "believe," "continue," "could," "should," and similar expressions.

Assumptions and Risks

Forward-looking information is based on assumptions management believes to be reasonable as of the date of publication, including, without limitation, assumptions regarding the Company's ability to carry out its exploration and business plans; the availability of financing, personnel, contractors, equipment, and services on reasonable terms; the timely receipt of required permits, approvals, and community support; and the continued validity of the Company's geological interpretations and exploration models. Forward-looking information is subject to known and unknown risks, uncertainties, and other factors, many of which are beyond the Company's control, that could cause actual results to differ materially. These include, without limitation, risks inherent in mineral exploration and development; uncertainty in the interpretation of geological data, historical information, and exploration results; permitting, environmental, Indigenous, and community-related risks; title, access, and infrastructure risks; equipment, contractor, and labour availability; the availability and cost of capital; commodity price, market, and currency volatility; regulatory and policy changes; and the other risks described in the Company's continuous disclosure record available on SEDAR+.

No Obligation to Update

Although the Company believes the assumptions and expectations reflected in the forward-looking information are reasonable, no assurance can be given that such information will prove accurate. Actual results may differ materially. Forward-looking information is made as of the date of this website, and the Company undertakes no obligation to update or revise it, whether as a result of new information, future events, or otherwise, except as required by applicable law. Readers should not place undue reliance on forward-looking information.

Exploration Target

The 300M+ lb antimony target referenced on this website is an exploration target. Its potential quantity and grade are conceptual in nature. There has been insufficient exploration to define a mineral resource at the Howells Lake project, and it is uncertain whether further exploration will result in the target being delineated as a mineral resource. The exploration target is not, and must not be interpreted as, a mineral resource or a mineral reserve.

Qualified Person, NI 43-101, and Technical Information

The scientific and technical information on this website relating to the Howells Lake Antimony-Gold Project, including the HWL-2026-006 drill results, and the KCR (Slam) gold occurrence has been reviewed and approved by Matthew Trenkler, PhD, P.Geo., Chief Geological Officer of Critical One Energy Inc., a "Qualified Person" as defined under National Instrument 43-101, Standards of Disclosure for Mineral Projects ("NI 43-101").

For the May 15, 2026 Howells Lake drill results, verification included a review of laboratory assay certificates, drill logs, chain-of-custody records, blank, standard, and duplicate statistics, and collar and down-hole survey data. No QA/QC failures were identified.

Reported intervals from HWL-2026-006 are core lengths, and true widths have not been estimated. Overlimit antimony results above 5% Sb were reanalyzed by pressed-pellet wavelength-dispersive XRF and should be considered semi-quantitative until confirmatory mineralogical and fully calibrated chemical analyses are completed. References to grades being near, at, or above a natural limit, comparisons to the approximate theoretical maximum antimony content of stibnite (about 71.7% Sb), and characterizations such as high grade or exceptional grade are provided for context only and do not imply any particular resource, reserve, recovery, or economic outcome. Commodity price references are provided for market context only and are not used to update, support, or validate any historical estimate.

Historical Information and Estimates

Unless otherwise indicated, certain scientific and technical information referenced on this website is historical in nature. Historical estimates, historical drill results, sampling, geophysical interpretations, and other historical technical information may be relevant to the Company's projects but have not been verified by the Qualified Person to the standard required for current disclosure. The Qualified Person has not done sufficient work to classify any historical estimate as a current mineral resource or mineral reserve, and the Company is not treating any historical estimate as a current mineral resource or mineral reserve.

Historical estimates were prepared before the enactment of NI 43-101 and the establishment of current CIM (Canadian Institute of Mining, Metallurgy and Petroleum) classification categories, and should not be relied upon for investment decisions. Significant data compilation, re-drilling, re-sampling, and data verification by a Qualified Person are required before any historical estimate could be classified as a current mineral resource. Mineral resources are not mineral reserves and do not have demonstrated economic viability. There can be no assurance that any historical estimate, in whole or in part, will be confirmed as a current mineral resource or ever become economically viable.

Howells Lake Historical Estimate

The historical estimate for the Howells Lake East Zone is approximately 1.7 million tonnes grading 1.4% Sb, with associated historical antimony grades of up to 75% Sb and historical gold intercepts. This historical estimate is derived from Themistocleous, S.G., 1980, Miminiska Lake Project Northwestern Ontario Geological Report, New Jersey Zinc Exploration Company (Canada) Ltd.

The Company is not treating this historical estimate as a current mineral resource or mineral reserve, and a Qualified Person has not done sufficient work to classify it as current. The Company presents this historical information to illustrate the project's potential to host a mineral inventory, and intends to work toward verifying it through modern drilling, sampling, and data verification. Other than the source noted above, the Company is not aware of more recent estimates or of technical reports describing the historical estimate. Readers should not rely on this historical estimate for investment decisions.

Direct-Shipping Ore and Metallurgy

References to direct-shipping ore (DSO) potential, or to material that could reach buyers with little processing, are conceptual and forward-looking. Any such outcome depends on future metallurgical, technical, permitting, and economic studies that have not been completed. No mineral resources or reserves have been estimated, no economic viability has been demonstrated, and no assurance is given that any material will be amenable to direct shipping or sold without further processing.

Neighbouring, Analogue, and Market Information

This website may refer to neighbouring, analogous, or regional projects, deposits, camps, infrastructure, or processing facilities, and to market, industry, commodity price, critical-mineral, and supply-chain information, including data attributed to the U.S. Geological Survey and references to third-party transactions such as government stockpile or defense procurement contracts. Such information is derived from publicly available third-party sources believed to be reliable but has not been verified by the Qualified Person or independently verified by the Company. Mineralization, development, or operating results on neighbouring or analogous properties are not necessarily indicative of mineralization or development potential at the Company's properties. Any third parties named are not affiliated with the Company, and references to them do not imply any partnership or endorsement, or that the Company will pursue or achieve comparable transactions or results.

Strategic Relationships and Advisors

The Company's memorandum of understanding with Green Infrastructure Partners is a non-binding arrangement that may not result in a definitive agreement. The participation of advisors, including retired military personnel, reflects private advisory roles only. It does not constitute an endorsement, contract, offtake arrangement, or assurance of support by any government, agency, military, or armed force. References to defense, military, and critical-mineral applications describe general end-uses of antimony and the broader market, and do not represent current or committed sales, contracts, or offtake by the Company.

Management Background

References to prior transactions, exits, valuations, market capitalizations, and value creation by members of the Company's management, board, or advisors relate to other companies and are provided for background only. Past performance is not indicative of future results, and there is no assurance that the Company will achieve similar outcomes.

"Outer Ring of Fire"

"Outer Ring of Fire" is a descriptive term used by the Company to refer to the area of Northern Ontario west of the Ring of Fire region. It does not imply that the Howells Lake project forms part of the Ring of Fire mineral deposits, or that it shares their geology, mineralization, infrastructure, or economic potential.

Financial Figures and Currency

Financial figures on this website, including treasury, program budgets, working capital, debt, market data, and insider and institutional ownership percentages, are presented as of the date indicated and are subject to change. Dollar amounts are in Canadian dollars unless expressly stated in U.S. dollars (US$).

Mineral Exploration Risk

The Company is an exploration-stage company. Mineral exploration is highly speculative, involves substantial risk, and most exploration projects do not become producing mines. There is no assurance that exploration will establish mineral resources or reserves, that the Howells Lake project will be developed, or that it will be commercially or economically viable.
