Hecla Mining Company

Registration Statement on Form S-3

Ladies and Gentlemen:

I am the General Counsel for Hecla Mining Company, a Delaware corporation (the “Company”), and have acted as securities counsel to the Company in connection with the preparation and filing of the Registration Statement on Form S-3 of the Company (the “Registration Statement”), filed on or about the date hereof with the Securities and Exchange Commission (the “Commission”), relating to the registration under the Securities Act of 1933, as amended (the “Act”), for resale from time to time by the selling shareholders, of up to 2,717,807 shares of the Company’s common stock (the “Shares”).

The Shares have been issued by the Company to the selling shareholders as contributions to the selling shareholders pursuant to four contribution agreements, two dated as of August 18, 2020 and two dated as of October 16, 2023, in the case of two selling shareholders. In the case of the third selling stockholder, the Hecla Charitable Foundation, it received Shares pursuant to a gift by the Company on January 19, 2021. In the case of the fourth selling stockholder, the Hecla Mining Company Pre-2005 Supplemental Excess Retirement Plan and Hecla Mining Company Post-2004 Supplemental Excess Retirement Plan, it received Shares pursuant to a contribution by the Company on each of January 27, 2021, October 14, 2022 and October 16, 2023.

In arriving at the opinions expressed below, I have examined originals, or copies certified or otherwise identified to my satisfaction as being true and complete copies of the originals, of such agreements, instruments and documents, corporate records, certificates of officers of the Company and of public officials and other instruments as I have deemed necessary or advisable to enable me to render these opinions. In my examination, I have assumed, without independent investigation, the genuineness of all signatures, the legal capacity and competency of all natural persons, the authenticity of all documents submitted to me as originals and the conformity to original documents of all documents submitted to me as copies. As to any facts material to these opinions, I have relied to the extent I deemed appropriate and without independent investigation upon statements and representations of officers and other representatives of the Company and others.

Based upon the foregoing, and subject to the assumptions, exceptions, qualifications and limitations set forth herein, I am of the opinion that the Shares outstanding on the date hereof are validly issued, fully paid and non-assessable.

The opinions and other matters in this letter are qualified in their entirety by, and subject to, the following:

I express no opinion as to the laws of any jurisdiction other than the Included Laws. For purposes of this opinion, the term “Included Laws” means the Laws of the State of Delaware that are, in my experience, normally applicable to the matters covered by my opinion, including the Delaware General Corporation Law, any applicable provisions of the Constitution of the State of Delaware, and applicable judicial decisions.
