Cautionary Statements

–3–

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 areintended to be covered by the safe harbor created by such sections and other applicable laws, including Canadian Securities laws. Such forward-looking statements may include, without limitation: (i) estimates of futureproduction and sales, including as a result of the #4 Shaft Project; (ii) estimates of future costs and cash cost, after by-product credits per ounce of silver/gold, including the expected cost of the #4 Shaft project; (iii) guidancefor 2015 for silver and gold production, silver equivalent production, cash cost, after by-product credits, capital expenditures and pre-development and exploration expenditures (which assumes metal prices of gold at$1,225/oz., silver at $17.25/oz., zinc at $0.90/lb. and lead at $0.95/lb. and US dollar/Canadian dollar at $0.91); (iv) expectations regarding the development, growth and exploration potential of the Company’s projects; (v)expectations of growth; (vi) expected level of hydroelectric usage at Greens Creek;(vii) the possibility of increasing production due to accessing higher grade material at Casa Berardi and possible strike extensions; (viii)possible strike extensions of veins at San Sebastian and estimates of mining, grade, recovery, free cash flow, mine life, IRR, ability to reactivate existing mill permits, production of silver, gold and silver equivalent ounces,ability to begin mining by year end; (ix) estimates or expectations of future events or results are based upon certain assumptions, which may prove to be incorrect; (x) the ability to Permit and bring Rock Creek into productionin 10-15 years; and (xii) expectations of grade increases at depth at Lucky Friday and the ability to complete the #4 Shaft project by Q4 2016 within the $225 Million budget. 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 withcurrent 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 Canadian dollar to theU.S. dollar, 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 ofour current mineral reserve and mineral resource estimates; and (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, whetherknown, unknown or unanticipated. Where the Company 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 reasonablebasis. 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-lookingstatements.” Such risks include, but are not limited to gold, silver and other metals price volatility, operating risks, currency fluctuations, increased production costs and variances in ore grade or recovery rates from thoseassumed in mining plans, community relations, conflict resolution and outcome of projects or oppositions, litigation, political, regulatory, labor and environmental risks, and exploration risks and results, including that mineralresources 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. For a more detailed discussion ofsuch risks and other factors, see the Company’s third quarter 2015 Form 10-Q and 2014 Form 10-K, filed on November 4, 2015 and February 18, 2015, respectively, with the Securities and Exchange Commission (SEC), aswell 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 orcircumstances after the date of this presentation, 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 apreviously issued “forward-looking statement” constitutes a reaffirmation of that statement. Continued reliance on “forward-loo king statements” is at investors’ own risk.

Cautionary Note Regarding Estimates of Measured, Indicated and Inferred ResourcesThe United States Securities and Exchange Commission (SEC) permits mining companies, in their filings with the SEC, to disclose only those mineral deposits that a company can economically and legally extract orproduce. 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 SEC guidelines generallyprohibit U.S. registered companies from including in their filings with the SEC, except in certain circumstances. U.S. investors are urged to consider closely the disclosure in our most recent Form 10-K and Form 10-Q. Youcan review and obtain copies of these filings from the SEC’s website at www.sec.gov.

Qualified Person (QP) Pursuant to Canadian National Instrument 43-101Dean McDonald, PhD. P.Geo., Senior Vice President - Exploration of Hecla Mining Company, who serves as a Qualified Person under National Instrument 43-101("NI 43-101"), supervised the preparation of the scientificand technical information concerning Hecla’s mineral projects in this presentation. Information regarding data verification, surveys and investigations, quality assurance program and quality control measures and a summaryof analytical or testing procedures for the Greens Creek Mine are contained in a technical report titled “Technical Report for the Greens Creek Mine” effective date March 28, 2013, and for the Lucky Friday Mine arecontained in a technical report titled “Technical Report for the Lucky Friday Mine Shoshone County, Idaho, USA” effective date April 2, 2014, for Casa Berardi are contained in a technical report titled "Technical Report onthe mineral resource and mineral reserve estimate for Casa Berardi Mine, Northwestern Quebec, Canada" effective date March 31, 2014 (the "Casa Berardi Technical Report"), and for the San Sebastian Mine, Mexico, arecontained in a technical report prepared for Hecla titled “Technical Report for the San Sebastian Ag-Au Property, Durango, Mexico” effective date September 8-K 2015 . Also included in these four technical reports is adescription of the key assumptions, parameters and methods used to estimate mineral reserves and resources and a general discussion of the extent to which the estimates may be affected by any known environmental,permitting, legal, title, taxation, socio-political, marketing or other relevant factors. Copies of these technical reports are available under Hecla's and Aurizon's profiles on SEDAR at www.sedar.com. The Casa BerardiTechnical Report was reviewed by Dr. McDonald on behalf of Hecla. To the best of Hecla's knowledge, information and belief, there is no new material scientific or technical information that would make the disclosure of themineral resources and mineral reserves for Casa Berardi in this document inaccurate or misleading.

Cautionary Note Regarding Non-GAAP measuresCash cost per ounce of silver and gold, net of by-product credits represents non-U.S. Generally Accepted Accounting Principles (GAAP) measurement. A reconciliation of this non-GAAP measure to the most comparableGAAP measurement can be found in the Appendix.

Ventilation & Refrigeration Requirements Are Increasing

The rock temperature increases 1°F for every 100ft of depth, current shaft rock temperature approaches 150°F.

The Centralized Refrigeration Plant will facilitate mining to 8,000 ft. of depth.

Ventilation is complicated by depth. Increasing depth equates to higher ventilation pressure and higher temperatures.

Ground Conditions Worsening & Seismicity Increasing

Intervention to control seismicity is done through:Measuring/monitoring (risk assessment) Altering mining geometry Pillars Mining abutment

Altering mining method Pre-conditioning Advance rate Remote Mining

Most mines that are over 3,000 feet deep have some level of seismicity. Seismicity has the potential for injury or damage.

Continuous Miner Could Provide a Step Change
