INTEGRA CLOSES US$61 MILLION BOUGHT DEAL FINANCING

Integra Resources Corp. has completed its previously announced bought deal public offering of 18,121,600 common shares of the company at a price of $3.40 (U.S.) per common share for aggregate gross proceeds of $61,613,440 (U.S.), including the full exercise of the overallotment option by the underwriters (as defined below). The offering was led by Canaccord Genuity Corp. and Stifel Nicolaus Canada Inc. as co-lead underwriters and joint bookrunners, on behalf of a syndicate of underwriters that included ATB Capital Markets Corp., Desjardins Securities Inc. and Raymond James Ltd.

The common shares were offered pursuant to a final prospectus supplement of the company dated Feb. 4, 2026, to the short form base shelf prospectus of the company dated Jan. 16, 2024, in all of the provinces of Canada, except Quebec, and in the United States pursuant to a prospectus supplement dated Feb. 4, 2026, filed as part of an effective registration statement on Form F-10 (file No. 333-276530) under the Canada/U.S. multijurisdictional disclosure system. The offering remains subject to the final approval of the TSX Venture Exchange.

The offering was completed pursuant to an underwriting agreement dated Feb. 4, 2026, entered into among the company and the underwriters. The company paid the underwriters a cash fee of 5 per cent of the aggregate gross proceeds of the offering, other than in respect of the purchasers on the president's list, for which a cash fee of 2.5 per cent was paid.

The company intends to use the net proceeds to finance preproduction capital expenditures at the DeLamar project, including procurement work, early works and land purchase.

George Salamis, president, chief executive officer and director of Integra, commented: "Following significant permitting milestones in early 2026 -- including receipt of a 15-month NEPA permitting timeline and FAST-41 project designation from U.S. federal regulators -- together with the recent filing of the DeLamar project feasibility study, this oversubscribed financing positions Integra to capitalize on a clear execution window. The feasibility study has defined the early works that can advance ahead of a record of decision, enabling us to fund procurement, land acquisition, and other low-risk activities that shorten the development timeline and reduce execution risk at DeLamar. Raising capital from a position of strength, supported by permitting visibility, reflects a disciplined approach that enhances project readiness, lowers future financing risk and supports a more efficient path toward a construction decision while minimizing long-term shareholder dilution."
