Corporate Update

On January 9, 2023, the Company announced it had entered into a definitive acquisition agreement to acquire the permitted, past-producing La Negra Mine in Mexico. The Company is continuing to take steps necessary to advance the acquisition and discussions with potential investors in the equity offering proposed to be completed in connection with the acquisition. The required meeting of Excellon shareholders to approve the issuances of Excellon common shares contemplated by the acquisition (including pursuant to the closing equity offering and restructuring of the Company’s outstanding debentures) and, in turn, completion of the acquisition, are now expected to occur no later than end of June (as opposed to the previously announced April target dates), subject to the successful completion of the proposed equity offering and receipt of conditional listing approval of the Toronto Stock Exchange in respect of the acquisition and related matters.  The Company is in discussions with the seller regarding the proposed timeline for the shareholder meeting and completion of the acquisition. The Company continues to strongly believe in the forward-looking value proposition of the La Negra acquisition to Excellon and its shareholders and remains optimistic that the acquisition and related transactions (including the closing equity offering) can be successfully completed in due course.

In addition, the Company is considering various other potential financing, corporate development and strategic opportunities that may include acquisitions, divestitures, mergers or spin-offs of the Company’s or third parties’ assets, as applicable, to compliment the Company’s go-forward strategy.

About Excellon

Excellon’s vision is to realize opportunities for the benefit of our employees, communities and shareholders, through the acquisition of advanced development or producing assets with further potential to gain from an experienced operational management team.  The Company is advancing a portfolio of gold, silver and base metals assets including Kilgore, an advanced gold exploration project in Idaho; and Silver City, a high-grade epithermal silver district in Saxony, Germany with 750 years of mining history and no modern exploration. The Company has also entered into an agreement to acquire La Negra, a past-producing Ag-Zn-Cu-Pb mine with exploration potential, located in Querétaro State, Mexico.

Mineral Resources

Until mineral deposits are actually mined and processed, mineral resources must be considered as estimates only. Mineral resource estimates that are not classified as mineral reserves do not have demonstrated economic viability. The estimation of mineral resources is inherently uncertain, involves subjective judgement about many relevant factors and may be materially affected by, among other things, environmental, permitting, legal, title, taxation, socio-political, marketing, or other relevant risks, uncertainties, contingencies and other factors described in the foregoing Cautionary Statements on Forward-Looking Statements. The quantity and grade of reported “inferred” mineral resource estimates are uncertain in nature and there has been insufficient exploration to define “inferred” mineral resource estimates as an “indicated” or “measured” mineral resource and it is uncertain if further exploration will result in upgrading “inferred” mineral resource estimates to an “indicated” or “measured” mineral resource category. The accuracy of any mineral resource estimates is a function of the quantity and quality of available data, and of the assumptions made and judgments used in engineering and geological interpretation, which may prove to be unreliable and depend, to a certain extent, upon the analysis of drilling results and statistical inferences that may ultimately prove to be inaccurate. The quantity and grade of “inferred” mineral resource estimates are uncertain in nature and there has been insufficient exploration to define “inferred” mineral resource estimates as an “indicated” or “measured” mineral resource and it is uncertain if further exploration will result in upgrading “inferred” mineral resource estimates to an “indicated” or “measured” mineral resource category. Mineral resource estimates may have to be re-estimated based on, among other things: (i) fluctuations in mineral prices; (ii) results of drilling and development; (iii) results of geological and structural modeling including stope design; (iv) metallurgical testing and other testing; (v) proposed mining operations including dilution; and (vi) the possible failure to receive and/or maintain required permits, licenses and other approvals. It cannot be assumed that all or any part of a “inferred”, “indicated” or “measured” mineral resource estimate will ever be upgraded to a higher category including a mineral reserve.

Mineral resource estimates disclosed by the Company were estimated and reported in accordance with National Instrument 43-101 of the Canadian Securities Administrators (“NI 43-101”) using Canadian Institute of Mining, Metallurgy and Petroleum (“CIM”) Definition Standards for Mineral Resources and Mineral Reserves (the “CIM Standards”), which govern the public disclosure of scientific and technical information concerning mineral projects by Canadian issuers such as Excellon, and applying the CIM’s Mineral Resources and Mineral Reserves Best Practices guidelines (as applicable). For additional discussion of the Company’s mineral resource estimates at the Company’s projects and La Negra, as well as an overall more detailed discussion of such projects, the reader should refer to the AIF and the applicable Technical Reports.

U.S. Readers

The terms “mineral resource”, “measured mineral resource”, “indicated mineral resource” and “inferred mineral resource” as disclosed by the Company are Canadian mining terms defined in the CIM Standards (collectively, the “CIM Definitions”) in accordance with NI 43-101. NI 43-101 establishes standards for all public disclosure that a Canadian issuer makes of scientific and technical information concerning mineral projects. These Canadian standards differ from the requirements of the SEC applicable to United States domestic and certain foreign reporting companies under Subpart 1300 of Regulation S-K (“S-K 1300”). Accordingly, information describing mineral resource estimates for the Company’s projects and La Negra, may not be comparable to similar information publicly reported in accordance with the applicable requirements of the SEC, and so there can be no assurance that any mineral resource estimate for the Company’s projects or La Negra would be the same had the estimates been prepared per the SEC’s reporting and disclosure requirements under applicable United States federal securities laws, and the rules and regulations thereunder, including but not limited to S-K 1300. Further, there is no assurance that any mineral resource or mineral reserve estimate that the Company may report under NI 43-101 would be the same had the Company prepared such estimates under S-K 1300.

Preliminary Economic Assessments (or PEAs)

A PEA, including the La Negra PEA, is only a conceptual study of the potential viability of the subject project’s mineral resource estimates, and the economic and technical viability of the project and its estimated mineral resources has not been demonstrated. A PEA is preliminary in nature and provides only an initial, high-level review of the subject project’s potential and design options; there is no certainty that a PEA will be realized. The conceptual LOM plan and economic model in a PEA include numerous assumptions and mineral resource estimates including inferred mineral resource estimates. Inferred mineral resource estimates are considered to be too speculative geologically to have any economic considerations applied to such estimates. Under NI 43-101, estimates of inferred mineral resources may not form the basis of feasibility studies, pre-feasibility studies or other economic studies, except in prescribed cases, such as in a preliminary economic assessment under certain circumstances. There is no guarantee that inferred mineral resource estimates will be converted to indicated or measured mineral resources, or that indicated or measured mineral resources can be converted to mineral reserves. Mineral resources that are not mineral reserves do not have demonstrated economic viability, and as such there is no guarantee the economics described in any PEA, including the La Negra PEA, will be achieved. Mineral resource estimates may be materially affected by environmental, permitting, legal, title, taxation, socio-political, marketing, or other relevant risks, uncertainties and other factors, as more particularly described in the foregoing other Cautionary Statements of this MD&A.
