Cautionary Statement Regarding Forward-Looking Information

This communication contains forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995, Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended. These forward-looking statements generally include statements regarding the potential transaction between McEwen and Timberline Resources, including any statements regarding the expected timetable for completing the potential transaction, the ability to complete the potential transaction, the expected benefits of the potential transaction, projected financial information, future opportunities, and any other statements regarding McEwen’s and the Company’s future expectations, beliefs, plans, objectives, results of operations, financial condition and cash flows, or future events or performance. These statements are often, but not always, made through the use of words or phrases such as “anticipates,” “expects,” “intends,” “plans,” “targets,” “forecasts,” “projects,” “believes,” “seeks,” “schedules,” “estimates,” “positions,” “pursues,” “may,” “could,” “should,” “will,” “budgets,” “outlook,” “trends,” “guidance,” “focus,” “on schedule,” “on track,” “is slated,” “goals,” “objectives,” “strategies,” “opportunities,” “poised,” “potential” and similar expressions. All such forward-looking statements are based on current expectations of McEwen’s and the Company’s management and therefore involve estimates and assumptions that are subject to risks, uncertainties and other factors that could cause actual results to differ materially from the results expressed in the statements. Key factors that could cause actual results to differ materially from those projected in the forward-looking statements include the ability to obtain the requisite Timberline Resources stockholder approval; uncertainties as to the timing to consummate the potential transaction; the risk that a condition to closing the potential transaction may not be satisfied; the effects of disruption to McEwen’s or the Company’s respective businesses; the effect of the potential transaction on the parties’ stock prices; the effects of industry, market, economic, political or regulatory conditions outside of the parties’ control; transaction costs; McEwen’s ability to achieve the benefits from the proposed transaction, McEwen’s ability to promptly, efficiently and effectively integrate acquired operations into its own operations; unknown liabilities; and the diversion of management time on transaction-related issues. Other important factors that could cause actual results to differ materially from those in the forward-looking statements include those described in the “Risk Factors” section of the Company’s most recent Annual Report on Form 10-K, as it may be updated from time to time by quarterly reports on Form 10-Q and current reports on Form 8-K all of which are available on the Company’s website at https://timberlineresources.co and on the SEC’s website at http://www.sec.gov, and in the “Risk Factors” section of McEwen’s most recent Annual Report on Form 10-K, as it may be updated from time to time by quarterly reports on Form 10-Q and current reports on Form 8-K, all of which are available on McEwen’s website at https://mcewenmining.com and on the SEC’s website at http://www.sec.gov. Those disclosures are incorporated by reference in this communication. Other unpredictable or unknown factors not discussed or incorporated by reference in this communication could also have material adverse effects on forward-looking statements. Neither the Company nor McEwen assumes any obligation to update any forward-looking statements, except as required by law. Readers are cautioned not to place undue reliance on these forward-looking statements, as they speak only as of the date hereof.
