CAUTION ON FORWARD-LOOKING INFORMATION

This website includes certain "forward-looking information" and "forward-looking statements" (collectively "forward-looking statements") within the meaning of applicable Canadian and United States securities legislation. All statements in this presentation that address events or developments that we expect to occur in the future are forward-looking statements. Forward-looking statements are statements that are not historical facts and are identified by words such as "expect", "plan", "anticipate", "project", "target", "potential", "schedule", "forecast", "budget", "estimate", "intend" or "believe" and similar expressions or their negative connotations, or that events or conditions "will", "would", "may", "could", "should" or "might" occur. Forward-looking statements within this website include, but are not limited to: Calibre Mining Corp.’s (“Calibre” or the “Company”) expectations toward higher grades mined and processed going forward, increased overall annual production and cash flow in 2024 and lower per ounce costs; statements and expectations with respect to production guidance, growth and optimization opportunities, and potential mineral reserve or mineral resource expansion in respect of the Company’s mineral properties; statements relating to the Company’s 2024 priority mineral resource expansion opportunities; the Company’s exploration focus at the El Limon Complex; the Company’s metal price and cut-off grade assumptions; the Company’s opportunities at Volcan and Tranca at the La Libertad Complex; the Company’s plans for the La Libertad Complex for 2024; the anticipated dates and costs of construction, mining and commercial production at the Valentine Gold Mine and the Company’s expectations with respect to Valentine and all assets and contributions to production growth and expected timing for completion; expectations regarding the potential benefits and synergies of the assets and the ability of the combined company to successfully achieve business objectives, including integrating the companies or the effects of unexpected costs, liabilities or delays; expectations regarding future exploration and development, growth potential for operations; and expectations for other economic, business, and/or competitive factors. Forward-looking statements necessarily involve assumptions, risks and uncertainties, certain of which are beyond Calibre's control. For a listing of risk factors applicable to the Company, please refer to Calibre's annual information form (“AIF”) for the year ended December 31, 2023, and its management discussion and analysis (“MD&A”) for the year ended December 31, 2023, all available on the Company’s SEDAR+ profile at www.sedarplus.ca. This list is not exhaustive of the factors that may affect Calibre's forward-looking statements such as potential sanctions implemented as a result of the United States Executive Order 13851 dated October 24, 2022.

Calibre's forward-looking statements are based on the applicable assumptions and factors management considers reasonable as of the date hereof, based on the information available to management at such time. Such assumptions include, but are not limited to: the Company being able to mine and process higher grades and keep production costs relatively flat going forward; there not being an increase in production costs as a result of any supply chain issues or ongoing COVID-19 restrictions; there being no adverse drop in metal price or cut-off grade at the Company’s operating properties; the Company’s opportunities at Volcan and Tranca at the La Libertad Complex coming to fruition; there being no adverse development or hindrance in the permitting or construction processes at Volcan and Valentine and their respective potential and ability to contribute to production growth. Calibre does not assume any obligation to update forward-looking statements if circumstances or management's beliefs, expectations or opinions should change other than as required by applicable securities laws. There can be no assurance that forward-looking statements will prove to be accurate, and actual results, performance or achievements could differ materially from those expressed in, or implied by, these forward-looking statements. Accordingly, undue reliance should not be placed on forward-looking statements.

CAUTIONARY STATEMENT REGARDING MINERAL RESERVE AND RESOURCE ESTIMATES

This website and the materials posted on it have been prepared in accordance with the requirements of the securities laws in effect in Canada, which differ from the requirements of U.S. securities laws.  All Mineral Resource and Reserve estimates included on this website and the materials posted on it have been prepared in accordance with National Instrument 43-101 Standards of Disclosure for Mineral Projects (“NI 43-101”). NI 43-101 is a rule developed by the Canadian Securities Administrators that establishes standards for all public disclosure an issuer makes of scientific and technical information concerning mineral projects.  These standards differ significantly from the mineral reserve disclosure requirements of the SEC set out in Industry Guide 7. Consequently, reserve and resource information contained on this website and the materials posted on it are not comparable to similar information that would generally be disclosed by U.S. companies in accordance with SEC standards.

In particular, the SEC’s Industry Guide 7 applies different standards in order to classify mineralization as a reserve. As a result, the definitions of proven and probable reserves used in NI 43-101 differ from the definitions in SEC Industry Guide 7. Under SEC standards, mineralization may not be classified as a “reserve” unless the determination has been made that the mineralization could be economically and legally produced or extracted at the time the reserve determination is made.  Among other things, all necessary permits would be required to be in hand or issuance imminent in order to classify mineralized material as reserves under the SEC standards. Accordingly, Mineral Reserve Estimates contained on this website and the materials posted on it may not qualify as “Reserves” under SEC standards.

In addition, this website and the materials posted on it uses the terms “Mineral Resources”, “Measured Mineral Resources”, “Indicated Mineral Resources” and “Inferred Mineral Resources” to comply with the reporting standards in Canada. The SEC’s Industry Guide 7 does not recognize these categories and U.S. companies are generally not permitted to disclose them in documents they file with the SEC. Investors are specifically cautioned not to assume that any part or all of any mineral deposits in these categories will ever be converted into mineral reserves under SEC standards. Further, “Inferred Mineral Resources” have a great amount of uncertainty as to their existence and as to whether they can be mined legally or economically. Therefore, investors are also cautioned not to assume that all or any part of an inferred mineral resource exists. In accordance with Canadian rules, estimates of “Inferred Mineral Resources” cannot form the basis of feasibility or, except in limited circumstances, other economic studies. It cannot be assumed that all or any part of “Indicated Mineral Resources” or “Inferred Mineral Resources” will ever be upgraded to a higher category of mineral resources or that mineral resources will be classified as Mineral Reserves. Investors are cautioned not to assume that any part of the reported “Measured Mineral Resources”, “Indicated Mineral Resources” or “Inferred Mineral Resources” on this website and the materials posted on it are economically or legally mineable. Disclosure of “contained ounces” is permitted under the Canadian disclosure rules; however, the SEC normally only permits issuers to report mineralization that do not constitute reserves as in place tonnage and grade without reference to unit measures. Further, while NI 43-101 permits companies to disclose economic projections contained in preliminary economic assessments which are not based on “Mineral Reserves”, U.S. companies are not normally permitted to disclose economic projections for a mineral property in their SEC filings prior to the establishment of “mineral reserves.” For the above reasons, information contained on this website and the materials posted on it that describes the Company’s Mineral Reserve and Resource Estimates or that describes the results of pre-feasibility or other studies is not comparable to similar information made public by U.S. companies subject to the reporting and disclosure requirements of the SEC.

NON-IFRS MEASURES

The Company believes that investors use certain non-IFRS measures as indicators to assess gold mining companies, specifically Total Cash Costs per Ounce and All-In Sustaining Cash Costs per Ounce. In the gold mining industry, these are common performance measures but do not have any standardized meaning. The Company believes that, in addition to conventional measures prepared in accordance with IFRS, certain investors use this information to evaluate the Company’s performance and ability to generate cash flow. Accordingly, it is intended to provide additional information and should not be considered in isolation or as a substitute for measures of performance prepared in accordance with IFRS.

(1) Total Cash Costs per Ounce of Gold: Total cash costs include mine site operating costs such as mining, processing and local administrative costs (including stock-based compensation related to mine operations), royalties, production taxes, mine standby costs and current inventory write downs, if any.  Production costs are exclusive of depreciation and depletion, reclamation, capital and exploration costs.  Total cash costs per gold ounce are net of by-product silver sales and are divided by gold ounces sold to arrive at a per ounce figure.

(2) All-In Sustaining Costs per Ounce of Gold:  A performance measure that reflects all of the expenditures that are required to produce an ounce of gold from current operations.  While there is no standardized meaning of the measure across the industry, the Company’s definition is derived from the AISC definition as set out by the World Gold Council in its guidance dated June 27, 2013 and November 16, 2018.  The World Gold Council is a non-regulatory, non-profit organization established in 1987 whose members include global senior mining companies. The Company believes that this measure will be useful to external users in assessing operating performance and the ability to generate free cash flow from current operations.  The Company defines AISC as the sum of total cash costs (per above), sustaining capital (capital required to maintain current operations at existing levels), capital lease repayments, corporate general and administrative expenses, in-mine exploration expenses and rehabilitation accretion and amortization related to current operations.  AISC excludes capital expenditures for significant improvements at existing operations deemed to be expansionary in nature, exploration and evaluation related to growth projects, rehabilitation accretion and amortization not related to current operations, financing costs, debt repayments, and taxes.  Total all-in sustaining costs are divided by gold ounces sold to arrive at a per ounce figure.
