Cautionary Statements
Neither the TSX Venture Exchange (“TSX-V”) nor its Regulation Services Provider (as that term is defined in the policies of the TSX-V) accepts responsibility for the adequacy or accuracy of this news release.
Certain statements in this news release are forward-looking and involve a number of risks and uncertainties. Such forward-looking statements are within the meaning of that term in Section 27A of the Securities Act and Section 21E of the U.S. Securities Exchange Act of 1934, as amended, as well as within the meaning of the phrase ‘forward-looking information’ in the Canadian Securities Administrators’ National Instrument 51-102 – Continuous Disclosure Obligations (collectively, “forward-looking statements”). Forward-looking statements are not comprised of historical facts. Forward-looking statements include estimates and statements that describe the Company’s future plans, objectives or goals, including words to the effect that the Company or management expects a stated condition or result to occur. Forward-looking statements may be identified by such terms as “believes”, “anticipates”, “expects”, “estimates”, “may”, “could”, “would”, “will”, “plan” or variations of such words and phrases.
Forward-looking statements in this news release include, but are not limited to, the expectation that the Promissory Note will provide sufficient short-term funding and the closing of brokered and non-brokered private placements. Forward-looking statements reflect material expectations and assumptions, including, without limitation, expectations and assumptions relating to: Bunker Hill’s ability to close the private placements and ongoing capital restructuring and to receive sufficient project financing for the restart and development of the Project on an acceptable timeline, on acceptable terms, or at all; our ability to service our existing debt and meet the payment obligations thereunder, including following the restructuring transactions, if completed; further drilling and geotechnical work supporting the planned restart and operations at the Bunker Hill Zinc-Silver-Lead Mine (the “Project”); the future price of metals; and the stability of the financial and capital markets. Factors that could cause actual results to differ materially from such forward-looking statements include, but are not limited to, those risks and uncertainties identified in public filings made by Bunker Hill with the U.S. Securities and Exchange Commission (the “SEC”) and with applicable Canadian securities regulatory authorities, and the following: Bunker Hill’s ability to operate as a going concern and its history of losses; Bunker Hill’s inability to raise additional capital for project activities, including through equity financings, concentrate offtake financings or otherwise; the fluctuating price of commodities; capital market conditions; restrictions on labor and its effects on international travel and supply chains; failure to identify mineral resources; further geotechnical work not supporting the continued development of the Project or the results described herein; failure to convert estimated mineral resources to reserves; the preliminary nature of metallurgical test results; the Company’s ability to raise sufficient project financing, on acceptable terms or at all, to restart and develop the Project and the risks of not basing a production decision on a feasibility study of mineral reserves demonstrating economic and technical viability, resulting in increased uncertainty due to multiple technical and economic risks of failure which are associated with this production decision including, among others, areas that are analyzed in more detail in a feasibility study, such as applying economic analysis to resources and reserves, more detailed metallurgy and a number of specialized studies in areas such as mining and recovery methods, market analysis, and environmental and community impacts and, as a result, there may be an increased uncertainty of achieving any particular level of recovery of minerals or the cost of such recovery, including increased risks associated with developing a commercially mineable deposit, with no guarantee that production will begin as anticipated or at all or that anticipated production costs will be achieved; the Company requiring additional capital expenditures than anticipated, resulting in delays in the expected restart timeline; failure to commence production would have a material adverse impact on the Company’s ability to generate revenue and cash flow to fund operations; failure to achieve the anticipated production costs would have a material adverse impact on the Company’s cash flow and future profitability; delays in obtaining or failures to obtain required governmental, environmental or other project approvals; political risks; changes in equity markets; uncertainties relating to the availability and costs of financing needed in the future; the inability of the Company to budget and manage its liquidity in light of the failure to obtain additional financing, including the ability of the Company to complete the payments pursuant to the terms of the agreement to acquire the Project complex; inflation; changes in exchange rates; fluctuations in commodity prices; delays in the development of projects; and capital, operating and reclamation costs varying significantly from estimates and the other risks involved in the mineral exploration and development industry. Although the Company believes that the assumptions and factors used in preparing the forward-looking statements in this news release are reasonable, undue reliance should not be placed on such statements or information, which only applies as of the date of this news release, and no assurance can be given that such events will occur in the disclosed time frames or at all, including as to whether or when the Company will achieve its project finance initiatives, or as to the actual size or terms of those financing initiatives, or whether and when the Company will achieve its operational and construction targets. The Company disclaims any intention or obligation to update or revise any forward-looking information, whether as a result of new information, future events or otherwise, other than as required by law. No stock exchange, securities commission or other regulatory authority has approved or disapproved the information contained herein.
