## Exhibit 99.2

**Exhibit 99.2**

**HECLA MINING COMPANY**

**UNAUDITED PRO FORMA CONDENSED CONSOLIDATED FINANCIAL INFORMATION**

The unaudited pro forma condensed consolidated financial information contained herein is prepared in accordance with Article 11 of Regulation S-X and should be read in conjunction with the accompanying notes. The following unaudited pro forma condensed consolidated financial statements were prepared to give effect to the disposal by Hecla Mining Company ("us", "we", the "Company" or "Hecla") of our wholly-owned subsidiary Hecla Quebec Inc. disposal (the "disposal"). The disposal will be presented as a discontinued operation in our Consolidated Financial Statements.

On January 26, 2026, we announced that we had entered into a material definitive agreement for the disposal of our Hecla Quebec Inc. subsidiary which owns the Casa Berardi segment and various exploration properties in Quebec, Canada to an affiliate of Orezone Gold Corporation ("Orezone") for up to $593 million in total consideration comprised of the following:

● Cash consideration of $160 million due upon closing;

● Equity consideration of approximately 65.8 million Orezone common shares, to be issued upon closing;

● Deferred cash consideration of $30 million and $50 million to be paid at 18 months and 30 months, respectively, from closing; and

● Contingent consideration of up to $241 million consisting of:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;o Production-based royalty payments of up to $211 million ($80/ounce for the first 500,000 ounces, then $180/ounce thereafter from open pit operations)

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;o Permit receipt payment of $20 million upon grant of permits

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;o Gold price-linked payment of up to $10 million at gold prices exceeding $4,200/ounce.

Under the terms of the transaction, (i) Orezone is entitled to reduce future deferred cash payments or contingent royalty payments owed to us if the financial assurance required under Casa Berardi's updated closure plan exceeds $150.0 million, by 50% of such amount and (ii) On April 24, 2026 a working capital true up adjustment will be made to reflect any difference between actual and targeted working capital agreed upon between Hecla and Orezone.

On March 25, 2026, the disposal closed and we received cash consideration of $160 million and 65,757,265 Orezone shares valued at $95.5 million. We intend to utilize the $160 million cash consideration received and existing cash resources to call and redeem the remaining $263 million 7.25% Senior Notes due February 15, 2028 ("Senior Notes"). We issued $475 million Senior Notes on February 19, 2020, and called and redeemed $212 million Senior Notes during 2025.

The unaudited pro forma condensed consolidated financial information is presented on the basis that we will utilize the cash proceeds received from the disposition and existing the cash resources to call and redeem $263 million of Senior Notes. The unaudited pro forma condensed consolidated financial information and related notes present our historical condensed consolidated balance sheet and historical condensed consolidated statement of operations adjusted to reflect the impact of the disposal that are (i) directly attributable to the disposal and (ii) factually supportable.

The unaudited pro forma condensed consolidated financial information for the years ended December 31, 2025, 2024 and 2023 and as of December 31, 2025, has been derived from our audited consolidated financial statements for the years ended December 31, 2025, 2024 and 2023. The unaudited pro forma condensed consolidated financial information has been prepared as if the disposal was completed as of January 1, 2023, in the case of the unaudited pro forma condensed consolidated statement of operations, and on December 31, 2025, in the case of the unaudited pro forma condensed consolidated balance sheet. The unaudited pro forma condensed consolidated presentation of the consideration received is preliminary and subject to adjustment. The final allocation of consideration among the derecognized assets and liabilities may differ materially from the amounts shown as of the applicable closing dates.

The unaudited pro forma condensed consolidated financial information does not purport to project our future operating results and should be read in conjunction with the accompanying notes.

This unaudited pro forma condensed consolidated financial information, including the related notes, is derived from, and should be read in conjunction with, our audited consolidated financial statements, which are available in our Annual Report on Form 10-K for the year ended December 31, 2025, as filed with the SEC on February 18, 2026.

**Sale of Hecla Quebec Inc.**

On January 26, 2026, we announced that we had entered into a material definitive agreement for the disposal of our Hecla Quebec Inc. subsidiary which owns the Casa Berardi segment to Orezone Gold Corporation ("Orezone") for up to $593 million in total consideration comprised of the following:

● Cash consideration of $160 million due upon closing;

● Equity consideration of approximately 65.8 million Orezone common shares, to be issued upon closing;

● Deferred cash consideration of $30 million and $50 million to be paid at 18 months and 30 months, respectively, from closing; and

● Contingent consideration of up to $241 million consisting of:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;o Production-based royalty payments of up to $211 million ($80/ounce for the first 500,000 ounces, then $180/ounce thereafter from open pit operations)

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;o Permit receipt payment of $20 million upon grant of permits

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;o Gold price-linked payment of up to $10 million at gold prices exceeding $4,200/ounce.

Under the terms of the transaction, (i) Orezone is entitled to reduce future deferred cash payments or contingent royalty payments owed to us if the financial assurance required under Casa Berardi's updated closure plan exceeds $150.0 million, by 50% of such amount and (ii) On April 24, 2026 a working capital true up adjustment will be made to reflect any difference between actual and targeted working capital agreed upon between Hecla and Orezone.

We intend to utilize the $160 million cash consideration received and existing cash resources to call and redeem the remaining $263 million 7.25% Senior Notes due February 15, 2028 ("Senior Notes"). We issued $475 million Senior Notes on February 19, 2020, and called and redeemed $212 million Senior Notes during 2025.
