SAFE HARBOR STATEMENT

Cautionary Statement Regarding Forward Looking Statements

This presentation contains “forward-looking statements” within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended, which are intended to be covered by the safe harbor created by such sections and other applicable laws, including Canadian securities laws. When a forward-looking statement expresses or implies an expectation or belief as to future events or results, such expectation or belief is expressed in good faith and believed to have a reasonable basis. However, such statements are subject to risks, uncertainties and other factors, which could cause actual results to differ materially from future results expressed, projected or implied by the forward-looking statements. Forward-looking statements often address our expected future business and financial performance and financial condition and often contain words such as “anticipate,” “intend,” “plan,” “will,” “could,” “would,” “estimate,” “should,” “expect,” “believe,” “project,” “target,” “indicative,” “preliminary,” “potential” and similar expressions. Forward-looking statements in this presentation may include, without limitation: : (i) expected increase in Lucky Friday’s silver production to approximately 5 million ounces by 2023; (ii) new mining methods being tested at Lucky Friday to better manage seismicity and potentially increase productivity; (ii) Green Creek's estimated 2021 silver production of 9.5 - 10.2 million ounces is unchanged and gold production increased to 43 - 45 thousand ounces, estimate for 2021 cost of sales updated to $222 million, estimated cash cost and AISC, each per silver ounce updated to ($1.00)-$1.00 and $3.25-$4.00, respectively; (iii) Casa Berardi's estimated 2021 gold production is increased to 128 - 132 thousand ounces, estimate for 2021 cost of sales updated to $220 million, estimated cash cost and AISC, each per gold ounce updated to $1,000-$1,125 and $1,200-$1,325, respectively; (iv) Lucky Friday's estimated 2021 silver production of 3.4 - 3.8 million ounces is unchanged, estimate for 2021 cost of sales updated to $103 million, estimated cash cost and AISC, each per silver ounce updated to $7.60-$8.50 and $14.25-$16.25, respectively; (v) business improvement activities at Casa Berardi are expected to reduce costs and increase cash flow over next two years; and (vi) Company-wide estimates of future production, sales, costs of sales, cash cost, after by-product credits, AISC, after by-product credits, as well as estimated spending on capital, exploration and pre-development for 2021.The material factors or assumptions used to develop such forward-looking statements or forward-looking information include that the prices assumed in the calculation of cash cost and AISC will occur and the Company’s plans for development and production will proceed as expected and will not require revision as a result of risks or uncertainties, whether known, unknown or unanticipated, to which the Company’s operations are subject.
.
Estimates or expectations of future events or results are based upon certain assumptions, which may prove to be incorrect, which could cause actual results to differ from forward-looking statements. Such assumptions, include, but are not limited to: (i) there being no significant change to current geotechnical, metallurgical, hydrological and other physical conditions; (ii) permitting, development, operations and expansion of the Company’s projects being consistent with current expectations and mine plans; (iii) political/regulatory developments in any jurisdiction in which the Company operates being consistent with its current expectations; (iv) the exchange rate for the USD/CAD and USD/MXN, being approximately consistent with current levels; (v) certain price assumptions for gold, silver, lead and zinc; (vi) prices for key supplies being approximately consistent with current levels; (vii) the accuracy of our current mineral reserve and mineral resource estimates; (viii) the Company’s plans for development and production will proceed as expected and will not require revision as a result of risks or uncertainties, whether known, unknown or unanticipated; (ix) counterparties performing their obligations under hedging instruments and put option contracts; (x) sufficient workforce is available and trained to perform assigned tasks; (xi) weather patterns and rain/snowfall within normal seasonal ranges so as not to impact operations; (xii) relations with interested parties, including Native Americans, remain productive; (xiii) economic terms can be reached with third-party mill operators who have capacity to process our ore; (xiv) maintaining availability of water rights; (xv) factors do not arise that reduce available cash balances; and (xvi) there being no material increases in our current requirements to post or maintain reclamation and performance bonds or collateral related thereto.

In addition, material risks that could cause actual results to differ from forward-looking statements include, but are not limited to: (i) gold, silver and other metals price volatility; (ii) operating risks; (iii) currency fluctuations; (iv) increased production costs and variances in ore grade or recovery rates from those assumed in mining plans; (v) community relations; (vi) conflict resolution and outcome of projects or oppositions; (vii) litigation, political, regulatory, labor and environmental risks; (viii) exploration risks and results, including that mineral resources are not mineral reserves, they do not have demonstrated economic viability and there is no certainty that they can be upgraded to mineral reserves through continued exploration; (ix) the failure of counterparties to perform their obligations under hedging instruments; (x) we take a material impairment charge on our Nevada operations; (xi) we are unable to remain in compliance with all terms of the credit agreement in order to maintain continued access to the revolver, and (xii) we are unable to refinance the maturing senior notes. For a more detailed discussion of such risks and other factors, see the Company’s 2020 Form 10-K, filed on February 18, 2021, with the Securities and Exchange Commission (SEC), as well as the Company’s other SEC filings. The Company does not undertake any obligation to release publicly revisions to any “forward-looking statement,” including, without limitation, outlook, to reflect events or circumstances after the date of this news release or to reflect the occurrence of unanticipated events, except as may be required under applicable securities laws. Investors should not assume that any lack of update to a previously issued “forward-looking statement” constitutes a reaffirmation of that statement. Continued reliance on “forward-looking statements” is at investors’ own risk.

Cautionary Note Regarding Estimates of Measured, Indicated and Inferred Resources

The disclosures herein regarding mineral reserves and resources are as of December 31, 2020. For disclosures prior to January 1, 2021, the SEC permits mining companies, in their filings with the SEC, to disclose only those mineral deposits that a company can economically and legally extract or produce. We use certain terms in this presentation, such as “resource,” “measured resources,” “indicated resources,” and “inferred resources” that are recognized by Canadian regulations, but that prior to January 1, 2021, SEC guidelines generally prohibited U.S. registered companies from including in their filings with the SEC.  U.S. investors are urged to consider closely the disclosure in our most recent Form 10-K and Form 10-Q. You can review and obtain copies of these filings from the SEC’s website at www.sec.gov.
