Auditor Opinion [Text Block] We have audited the accompanying consolidated balance sheet of U.S. Gold corp. (the “Company”) as of April 30, 2026, the related consolidated statements of operations, changes in stockholders’ equity and cash flows for the year ended April 30, 2026, and the related notes (collectively referred to as the “financial statements”). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Company as of April 30, 2026, and the results of its operations and its cash flows for the year ended April 30, 2026, in conformity with accounting principles generally accepted in the United States of America.The accompanying consolidated financial statements have been prepared assuming that the Company will continue as a going concern. As more fully described in Note 3, the Company has a significant working capital deficiency, has incurred significant losses and needs to raise additional funds to meet its obligations and sustain its operations. These conditions raise substantial doubt about the Company’s ability to continue as a going concern. Management’s plans in regard to these matters are also described in Note 3. The consolidated financial statements do not include any adjustments that might result from the outcome of this uncertainty.
