All statements other than statements of historical fact contained in this report, including statements regarding our future results of operations and financial position, business strategy, plans, and objectives of management for future operations, are forward-looking statements. In some cases, you can identify forward-looking statements by terms such as “anticipate,” “believe,” “estimate,” “expect,” “intend,” “plan,” “predict,” “project,” “target,” “will,” or the negative of these terms or other similar expressions. These forward-looking statements include, but are not limited to, statements regarding: our ability to successfully advance and restart mining and milling operations at the Sunshine Mine; the expected timing, execution, and success of our planned late 2028 production restart; the timing of completion of our Sunshine Mine Feasibility Study and the related final investment decision; the timing of completion of feasibility studies with respect to the new Antimony Plant and the refurbishment of the existing Silver-Copper Refinery, the timing for completion of the ongoing 50,000-meter drilling program; our plans for decommissioning the existing mill; our plans for a new mill designed to process up to 2,000 tonnes per day; our ability to initiate restart of our operations without an environmental impact study; and our expectations regarding the maintenance of our current permitting status and ability to secure the outstanding and ongoing permits required; the potential production capacity and products from the Silver-Copper Refinery; and the potential processing profile and capacity of the Antimony Plant. Forward-looking statements involve known and unknown risks, uncertainties, and other factors that may cause our actual results, performance, or achievements to be materially different from any future results, performance, or achievements expressed or implied by the forward-looking statements. These risks include, but are not limited to: • our lack of historical operating revenues and difficulties in achieving profitable operations; • our lack of Proven Mineral Reserves or Probable Mineral Reserves and the uncertainties around the calculation of Mineral Resource estimates; • changes in metal prices; • the speculative nature of mineral exploration efforts; • the requirement to obtain additional financing to bring the Sunshine Mine into production; • risks associated with establishing new mining operations and the risks and hazards inherent in the mining industry; • competition for skilled labor, mining equipment and supplies; • labor relations; • health and safety impacts including in connection with public health crises; • our ability to obtain, maintain and renew environmental, construction and mining permits; • future legislation and changes in laws and regulations; and • other risks and hazards association with exploration, development and mining operations. More detailed information regarding applicable risks and uncertainties is included in the section titled “Risk Factors” in our Form S-1 filed with the SEC on May 11, 2026, as amended. Many of these factors are beyond our ability to control or predict. Given these uncertainties, readers are cautioned not to place undue reliance on our forward-looking statements. The forward-looking statements made in this report relate only to events as of the date on which the statements are made. We undertake no obligation to update public forward-looking statements to reflect events or circumstances after the date of this report or to reflect the occurrence of unanticipated events, except as required by law 3 https://www.sec.gov/Archives/edgar/data/2091017/000162828026056217/ssmr-20260630.htm 4/36 8/12/26, 2:29 PM ssmr-20260630 TABLE OF CONTENTS Part I - Financial Information Item 1.
