The income and mining tax provision for the three and six months ended June 30, 2026 and 2025 varies from the amounts that would have resulted from applying the statutory tax rates to pre-tax income primarily due to the impact of taxation in foreign jurisdictions, domestic and foreign mining taxes, percentage depletion, non-recognition of net operating losses, the tax effect of Global Intangible Low-Taxed Income and subpart F income inclusion, foreign exchange gains and losses in certain jurisdictions, and the tax effects of the entity classification election discussed below.

For the three and six months ended June 30, 2026, we used the annual effective tax rate method to calculate the income and mining tax provision. During the quarter we filed and were approved for an Entity Classification Election to classify Klondex Mines Unlimited Liability Co as a disregarded entity effective January 1, 2026. Effective January 1, 2026, the Klondex (USA) Group joined the US consolidated Hecla Mining Company Group's income tax filings. Due to this change in entity classification, we released a portion of the valuation allowance and revalued the state deferred tax liabilities in our Klondex USA tax group. These amounts were treated as discrete adjustments within the tax provision.

We file income tax returns in U.S. federal and state jurisdictions. Our Canadian subsidiaries file income tax returns in Canada, as well as in the province of British Columbia, and the Yukon Territory. We will be filing a final income tax return for Hecla Quebec Inc. for the disposition of the Casa Berardi mine during the third quarter of 2026.
