INTEGRA CLOSES ACQUISITION OF STRATEGIC CLAIMS AT DELAMAR PROJECT

Further to Integra Resources Corp.'s news release dated Feb. 28, 2024, the company, through its wholly owned subsidiary, DeLamar Mining Company (DMC), has completed the acquisition of 17 patented claims in the Rich Gulch area. The Rich Gulch claims are located adjacent to the Florida Mountain deposit at the DeLamar project in Owyhee county, state of Idaho.

Rich Gulch is approximately two kilometres (1.2 miles) west-southwest of the Florida Mountain deposit at the base of the Jacobs Gulch stockpile. Control of the Rich Gulch claims at the project will provide operational flexibility to the company in future mining and processing scenarios. In the coming feasibility study, a development rock storage facility (DRSF) will be located at Rich Gulch to accommodate mining activities at the adjacent Florida Mountain deposit and Jacobs Gulch stockpile.

Summary terms of the acquisition

Under the terms of the option agreement dated Nov. 1, 2023, as between DMC and an arm's-length vendor, DMC has the option to purchase all of the member interests of Rich Gulch LLC, pursuant to a membership interest purchase agreement (the MIPA), to be entered into as between DMC and the vendor. Rich Gulch is the sole owner of the 17 patented Rich Gulch claims. On Feb. 28, 2024, DMC exercised the option and on March 8, 2024, the parties entered into the MIPA. Under the terms of the MIPA, DMC acquired all of the interests in exchange for $2.1-million (U.S.). The purchase price was satisfied through the issuance of 2,959,769 common shares in the capital of the company.

The shares are subject to a statutory hold period of four months and a day expiring on July 9, 2024, and a voluntary lock-up from which 25 per cent will be released 45 and 90 days, respectively, from closing, and 50 per cent to be released on Jan. 3, 2025.

As consideration for the grant of the option pursuant to the option agreement, DMC completed a $24,000 (U.S.) cash payment to the vendor.

No finder's fees were paid or are payable in connection with the acquisition.

The closing of the acquisition remains subject to the final approval of the TSX Venture Exchange.
