Hecla Mining est une société minière américaine spécialisée dans l'extraction de l'argent, de l'or et du zinc, opérant principalement aux États-Unis.

Une obligation d'entreprise émise par Hecla Mining, société minière majeure basée aux États-Unis et spécialisée dans la production de métaux précieux tels que l'argent et l'or, est actuellement disponible sur le marché au pair, soit à 100% de sa valeur nominale, portant le code ISIN US422704AH97 et le code CUSIP 422704AH9, et libellée en dollars américains (USD). Cette émission, d'une taille totale de 475 000 000 USD, offre aux investisseurs un taux d'intérêt annuel fixe de 7,25%, payable deux fois par an, avec une maturité fixée au 15 février 2028 et une taille minimale d'acquisition de 1 000 USD. La solvabilité de l'émetteur pour ce titre est évaluée par les agences de notation, avec une note de 'B' attribuée par Standard & Poor's et 'B3' par Moody's, plaçant ainsi cette obligation dans la catégorie spéculative (non-investment grade), ce qui implique un risque de crédit plus élevé en contrepartie d'un rendement potentiellement attractif.

Hecla Mining Company
$475,000,000
7.250% Senior Notes due 2028
Interest payable February 15 and August 15
Issue price: 100.00%
We are offering $475,000,000 aggregate principal amount of our 7.250% Senior Notes due 2028 (the "notes"). The notes will mature on February 15,
2028. Interest will accrue from February 19, 2020, and the first interest payment date will be August 15, 2020.
We intend to use the net proceeds from this offering, together with cash on hand, to redeem all of our outstanding 6.875% Senior Notes due 2021 (the
"2021 Notes") and to pay fees and expenses in connection with this offering, and the redemption of the 2021 Notes. See "Use of Proceeds."
We may redeem some or all of the notes at any time on or after February 15, 2023, at the redemption prices set forth in this prospectus supplement, plus
accrued and unpaid interest to, but excluding, the redemption date. We may also redeem up to 35% of the notes using the proceeds of certain equity
offerings completed before February 15, 2023, at a redemption price equal to 107.25% of the principal amount thereof, plus accrued and unpaid interest to,
but excluding, the redemption date. In addition, at any time prior to February 15, 2023, we may redeem some or all of the notes at a price equal to 100% of
the principal amount, plus a "make-whole" premium, plus accrued and unpaid interest to, but excluding, the redemption date. If we sell certain of our
assets or experience specific kinds of changes in control, we may be required to repurchase the notes. See "Description of the Notes--Optional
Redemption" and "Description of the Notes--Repurchase at the Option of Holders."
Each of our existing and future restricted subsidiaries that guarantees our indebtedness or indebtedness of subsidiary guarantors will guarantee the notes,
subject to certain exceptions. The notes will be our senior unsecured obligations and will rank equally in right of payment to all of our existing and future
senior indebtedness and senior in right of payment to all of our future subordinated indebtedness. The notes will be effectively subordinated to all of our
existing and future secured indebtedness, including our senior credit facility, to the extent of the value of the assets securing such indebtedness. The
guarantees will rank equally in right of payment with all of the guarantors' existing and future senior indebtedness and senior in right of payment to all of
the guarantors' future subordinated indebtedness. The guarantees will be effectively subordinated to all of the guarantors' existing and future secured
indebtedness, including our senior credit facility, to the extent of the value of the assets securing such indebtedness. In addition, the notes and the
guarantees will be structurally subordinated to all other liabilities of our non-guarantor subsidiaries. See "Description of the Notes."
See "Risk Factors" beginning on page S-17 for a discussion of certain risks that you should consider in connection with an investment in the notes.
Neither the Securities and Exchange Commission nor any state securities commission has approved or disapproved of these securities or passed
upon the adequacy or accuracy of this prospectus supplement or the accompanying prospectus. Any representation to the contrary is a criminal
offense.

About This Prospectus Supplement
This document is in two parts. The first part is this prospectus supplement, which describes certain matters relating to us and this offering. The
second part, the accompanying prospectus dated February 22, 2019, gives more general information about securities we may offer from time to time, some
of which may not apply to the notes offered by this prospectus supplement and the accompanying prospectus. For information about the notes and the
related guarantees, see "Description of the Notes" in this prospectus supplement and "Description of Debt Securities" and "Description of Guarantees" in
the accompanying prospectus.
We are responsible for the information contained and incorporated by reference in this prospectus supplement and the accompanying
prospectus and in any related free writing prospectus we prepare or authorize. We have not authorized anyone to give you any other information, and we
take no responsibility for any other information that others may give you. We are not, and the underwriters are not, making an offer of these notes in any
jurisdiction where the offer or sale is not permitted. You should not assume that the information contained in this prospectus supplement, the
accompanying prospectus, any free writing prospectus we may use or the documents incorporated by reference in this prospectus supplement or the
accompanying prospectus is accurate as of any date other than their respective dates. Our business, financial condition, results of operations and prospects
may have changed since those dates.
Before you invest in the notes, you should carefully read this prospectus supplement and the accompanying prospectus. You should also read
the documents we have referred you to under "Where You Can Find More Information" for information about us. The shelf registration statement
described in the accompanying prospectus, including the exhibits thereto, can be read at the web site of the Securities and Exchange Commission (the
"SEC") as described under "Where You Can Find More Information."
If the information set forth in this prospectus supplement varies in any way from the information set forth in the accompanying prospectus, you
should rely on the information contained in this prospectus supplement. If the information set forth in this prospectus supplement varies in any way from
the information set forth in a document we have incorporated by reference, you should rely on the information in the more recent document.
Unless indicated otherwise, or the context otherwise requires, references in this document to "Hecla," the "Company," "we," "us" and "our"
are to Hecla Mining Company and its consolidated subsidiaries, and references to "dollars" and "$" are to United States dollars.
Non-GAAP Financial Measures
In this prospectus supplement and the documents incorporated by reference in this prospectus supplement and the accompanying prospectus,
we disclose certain financial measures that are not presentations made in accordance with accounting principles generally accepted in the United States
("GAAP"), including "Adjusted EBITDA," "Cash costs, before by-product credits," "Cash costs, after by-product credits" and related per ounce measures.
These measures have important limitations as analytical tools. You should not consider these measures in isolation or as a substitute for analysis of our
results as reported under GAAP. In addition, these measures are defined differently by different companies in our industry, and, accordingly, such measures
as used in this prospectus supplement and the documents incorporated by reference in this prospectus supplement and the accompanying prospectus may
not be comparable to similarly titled measures of other companies. Accordingly, we have provided reconciliations of the non-GAAP measures used in this
prospectus supplement to the most directly comparable GAAP measures under "Summary -- Summary Historical Consolidated Financial Information."
Documents Incorporated by Reference
We file annual, quarterly and current reports and other information with the SEC. In this prospectus supplement and the accompanying
prospectus, we "incorporate by reference" the information that we file with the SEC, which means that we can disclose important information to you by
referring you to those documents.

Given these risks and uncertainties, readers are cautioned not to place undue reliance on our forward-looking statements. Projections and other
forward-looking statements included or incorporated by reference in this prospectus supplement or the accompanying prospectus have been prepared based

SUMMARY
This summary highlights selected information appearing elsewhere, or otherwise included or incorporated by reference, in this
prospectus supplement and the accompanying prospectus. This summary is not complete and does not contain all of the information that you should
consider before making an investment decision. For a more complete understanding of our company and this offering and before making any
investment decision, you should read this entire prospectus supplement and the accompanying prospectus, including "Risk Factors" and the financial
information and the notes thereto included or incorporated by reference in this prospectus supplement and the accompanying prospectus. In this
prospectus supplement, "we," "us," "our," "Hecla" or the "Company" refers to Hecla Mining Company and its subsidiaries, except as otherwise
indicated. With respect to the discussion of the terms of the notes on the cover page, in this summary of the offering and under the caption
"Description of the Notes," the terms "we," "us," "our," "Hecla" or the "Company" refer only to Hecla Mining Company, and not to any of its
subsidiaries.
Our Company
We are one of the oldest publicly-traded precious metals mining companies operating in the United States and, we believe, the largest
primary silver producer in the United States. We discover, acquire and develop mines and other mineral interests and produce and market
concentrates, loaded carbon, and precipitates containing gold and silver, and doré containing gold and silver. In doing so, we strive to manage our
business activities in a safe, environmentally responsible and cost-effective manner. We and our subsidiaries have provided precious and base metals
to the U.S. economy and worldwide since 1891 from northern Idaho's Silver Valley. We currently have operating mines in Alaska, Idaho, Nevada,
Quebec, Canada, and Durango, Mexico, exploration properties and pre-development projects in seven world-class silver mining districts in the United
States, Canada and Mexico, a corporate office in northern Idaho and secondary corporate offices in Vancouver, British Columbia, and Val d'Or,

Quebec. We are organized and managed in five segments that encompass our current operating units: the Greens Creek, Lucky Friday, Casa Berardi,
San Sebastian and Nevada Operations units. As of December 31, 2019, we had consolidated proven and probable reserves totaling approximately
212 million ounces of silver, approximately 2.7 million ounces of gold, approximately 1.0 million tons of zinc and approximately 811,000 tons of
lead.
For the year ended December 31, 2019, we produced 12,605,234 ounces of silver, 272,873 ounces of gold, 24,210 tons of lead, and
58,857 tons of zinc, and we generated sales of products of approximately $673.3 million, net loss of approximately $99.6 million and Adjusted
EBITDA of approximately $177.7 million. See Note 1 under "--Summary Historical Consolidated Financial Information" for a reconciliation of
Adjusted EBITDA to net (loss) income.
Our segments are differentiated by geographic region. We produce zinc, lead and bulk flotation concentrates at our Greens Creek unit and
lead and zinc flotation concentrates at our Lucky Friday unit, each of which we sell to custom smelters and metal traders on contract. The flotation
concentrates produced at our Greens Creek and Lucky Friday units contain payable silver, zinc and lead, and at Greens Creek they also contain
payable gold. At Greens Creek, we also produce gravity concentrate containing silver, gold and lead. Unrefined bullion (doré) is produced from the
gravity concentrate by a third-party processor, and shipped to a refiner before sale of the metals to precious metal traders. We also produce unrefined
gold and silver bullion bars (doré), loaded carbon and precipitates at our Casa Berardi, San Sebastian and Nevada Operations units, which are shipped
to refiners before sale of the metals to precious metals traders. At times, we sell loaded carbon and precipitates directly to refiners. Payable metals are
those included in our products for which we are paid by smelters, metal traders and refiners. Our segments as of December 31, 2019 included:

·
The Greens Creek unit located on Admiralty Island, near Juneau, Alaska. Greens Creek is 100% owned and has been in production

since 1989, with a temporary care and maintenance period from April 1993 through July 1996.

Unionized employees at Lucky Friday were on strike from mid-March 2017 until early January 2020, resulting in limited production

during that time. We expect re-staffing of the mine, which has commenced, to be completed in stages, with a return to full
production by the end of 2020.

The Casa Berardi unit located in the Abitibi region of northwestern Quebec, Canada. Casa Berardi is 100% owned and was acquired
on June 1, 2013 with the purchase of all issued and outstanding common shares of Aurizon Mines Ltd. ("Aurizon"). Aurizon had
operated and produced from the Casa Berardi mine since late 2006 and began various mine enhancements in an effort to improve
operational efficiency, including a shaft deepening project completed in 2014 and a new paste fill facility completed in 2013. In

addition to ongoing production from the underground mine, production from the East Mine Crown Pillar surface mine commenced
in July 2016. The addition of surface production and enhancements to the processing facility resulted in increased ore throughput
and gold production. We expect to recommence underground mining in the East Mine, which was the original production area, by
the end of 2020.

·
The San Sebastian unit located in the state of Durango, Mexico. San Sebastian is 100% owned and had previously produced for us
from underground mines between 2001 and 2005. Near-surface exploration discoveries in the vicinity of the past producing area led
to the decision in the third quarter of 2015 to develop shallow open pit mines there. Production commenced from the open pits in
the fourth quarter of 2015. Continued exploration resulted in the decision to develop a new underground ramp and rehabilitate the

historical underground access. The underground development commenced in the first quarter of 2017, and underground ore
production began in January 2018. During 2019, we commenced mining and processing of a bulk sample of underground sulfide
material. Testing of the bulk sample is part of an ongoing evaluation which we believe will allow us to determine the viability of
extending underground production there. We have also continued to advance additional surface exploration targets near our current
operations.

·
The Nevada Operations unit located in northern Nevada. Nevada Operations is 100% owned and was acquired on July 20, 2018
with the purchase of all of the issued and outstanding common shares of Klondex. Nevada Operations consists of three land
packages in northern Nevada totaling approximately 110 square miles and containing operating or previously-operating mines with
a history of high-grade gold production: Fire Creek, Hollister and Midas. We believe these properties to be prospective and under-

explored. The acquisition included the Midas mill and, in the Walker Lane district, the Aurora mine and mill. Klondex had owned
Fire Creek since 1975, Midas since 2014, and Hollister and Aurora since 2016. In the second quarter of 2019, we ceased
development to access new production areas at our Nevada operations until completion of studies and test work for hydrology,
mining and milling, resulting in, among other changes, an anticipated suspension of production in mid-2020.

Recent Developments
End of Strike at Lucky Friday
On January 6, 2020, the union representing hourly workers at our Lucky Friday mine in Mullan, Idaho ratified a new collective bargaining
agreement ("CBA") with the Company, and those workers are expected to return to work in stages throughout 2020. The new CBA is for a period of
four years and we believe contains many improvements over the last CBA that, after a ramp-up period to reintegrate the workforce, should lead to
increased productivity at the mine. The union had been on strike since March 13, 2017. We anticipate re-staffing of the mine to take place in stages,
with a ramp-up to full production levels expected by the end of 2020.
