THIS NEWS RELEASE IS INTENDED FOR DISTRIBUTION IN CANADA ONLY AND IS NOT INTENDED FOR DISTRIBUTION TO UNITED STATES NEWSWIRE SERVICES OR FOR DISSEMINATION IN THE UNITED STATES.

Integra Resources Corp. (" Integra ") (TSX-V: ITR; NYSE American: ITRG) and Millennial Precious Metals Corp. (" Millennial ") (TSX-V: MPM, OTCQB: MLPMF) (together, the " Companies ") are pleased to announce that they have entered into an arm's length definitive agreement dated February 26, 2023 for an at-market merger (the " Arrangement Agreement "), pursuant to which Integra and Millennial have agreed to combine their respective companies (the " Transaction ") by way of a court-approved plan of arrangement.

Under the terms of the Transaction, Millennial shareholders will receive 0.23 of a common share of Integra (each whole share, an " Integra Share ") for each Millennial common share (" Millennial Share ") held (the " Exchange Ratio "). Existing shareholders of Integra and Millennial will own approximately 65% and 35%, respectively, of the outstanding Integra Shares on the closing of the Transaction (but prior to the completion of the equity financing contemplated below). The Exchange Ratio implies consideration of C$0.18 per Millennial Share based on the closing market price of the Integra Shares on the TSX Venture Exchange (the " TSXV ") on February 24, 2023. The consideration represents a no premium Transaction.

In connection with the Transaction, the Companies are pleased to announce concurrent equity financings for aggregate gross proceeds of C$35 million, comprised of the Brokered Offering and Non-Brokered Offering (each, as defined below), the net proceeds of which are expected to be used by Integra, following completion of the Transaction, to fund an updated Mineral Resource Estimate and Mine Plan of Operations at the DeLamar Project, the preparation of a Mineral Resource Estimate and Preliminary Economic Assessment (" PEA ") on Millennial's Wildcat and Mountain View Projects, as well as on-going baseline work for additional permitting and exploration at the Companies' respective projects, and for working capital and general corporate purposes. The Companies are pleased to welcome Wheaton Precious Metals Corp. (TSX | NYSE | LSE: WPM) (" Wheaton ") as a new cornerstone investor, with Wheaton agreeing to invest an amount equal to up to 9.9% of the issued and outstanding Integra Shares (following the completion of the proposed Transaction and the conversion of the Subscription Receipts (as defined below) issuable to Wheaton and pursuant to the Brokered Offering (as defined below)). The equity participation of Wheaton in connection with the Transaction provides significant project and transaction validation while also creating a partnership for future project financing. The equity financing also includes participation by Beedie Investments Ltd. (" Beedie Capital "), an existing lender and shareholder of Integra.

The combination of Integra and Millennial will create one of the largest precious metals development and exploration companies in the Great Basin, with the goal of becoming a mid-tier heap leach gold-silver producer and generating significant value for shareholders. The combined company will feature a diversified portfolio of assets including Integra's past producing gold-silver DeLamar Project in southwest Idaho and Millennial's oxide-focused Wildcat and Mountain View Projects in western Nevada. The combined company will boast one of the largest gold-silver endowments in the Great Basin not controlled by a major mining company. In addition to the development pipeline, meaningful exploration potential exists in the BlackSheep, War Eagle and non-oxide targets at DeLamar and the Dune, Eden, Marr, Ocelot, Cerro Colorado ^{( 1 )} and Red Canyon ^{( 1 )} Projects from Millennial.

Strategic Rationale for Transaction

• Increased Scale : Combined portfolio consists of 10 high quality assets across various stages of development with a total measured and indicated resource containing 2.6 million ounces of gold and 126.9 million ounces of silver and an inferred resource of 1.65 million ounces of gold and 16.4 million ounces of silver. ^{( 2 ) , ( 3 ) , ( 4 )}
• Robust Pipeline : Focused on building a portfolio of low-risk, low-capital intensity and high-margin heap leach projects located in the Great Basin, considerably reducing risks commonly associated with single asset development and production companies.
• Industry Leading Growth : Near-term oxide resource growth potential identified at DeLamar, Wildcat and Mountain View, with the goal of becoming a +200kozs AuEq per annum producer using a staged development strategy, executed by one singular permitting and development team.
• The Right Team : Combining two of the leading junior gold exploration and development teams with a proven track record of success across exploration, construction, project finance, M&A and capital markets.
• Financial Strength : Concurrent equity offering, including strategic support from Wheaton and Beedie Capital, provides significant immediate funding and future financing support to advance key milestones at DeLamar, Wildcat & Mountain View.
  

George Salamis, President and Chief Executive Officer of Integra, stated , "The merger with Millennial is an exciting combination that provides balanced benefits to both sets of shareholders and streamlines the permitting and development of three high-quality, oxide, heap leach projects. The industry is in need of consolidation, and the support amongst the investment community and from Wheaton for this merger and concurrent financing has been resoundingly positive."

Jason Kosec, President and Chief Executive Officer of Millennial, stated, "The result of this transaction will be a combined company with a greatly strengthened balance sheet, an enhanced leadership team, and a high-quality asset portfolio with three flagship heap leach projects in the Great Basin. This represents a significant step toward our long-term vision of building an industry leading USA-focused mid-tier gold producer."

Randy Smallwood, President and Chief Executive Officer of Wheaton Precious Metals, commented , "We are pleased to support this transaction between Integra and Millennial and the much-needed consolidation in the industry. We look forward to becoming a meaningful shareholder of the combined entity, which provides Wheaton the opportunity of gaining exposure to high-quality exploration and development assets in one of the top mining jurisdictions in the world."

Non-Brokered Offering

Pursuant to a binding letter agreement, Wheaton has agreed to purchase the lesser of: (a) C$15 million of Subscription Receipts at the Issue Price; (b) such number of Subscription Receipts that will result in Wheaton owning 9.9% of the issued and outstanding Integra Shares (following the completion of the proposed Transaction and the conversion of the Subscription Receipts issuable to Wheaton and pursuant to the Brokered Offering); and (c) 30% of the combined Subscription Receipts to be issued to Wheaton and investors in the Brokered Offering (the " Non-Brokered Offering "). The Non-Brokered Offering is expected to close concurrently with the Brokered Offering and is subject to TSXV and other necessary regulatory approvals, and execution of definitive agreements. No fee or commission shall be payable on the sale of Subscription Receipts to Wheaton pursuant to the Non-Brokered Offering.

Beedie Capital Credit Facility

In connection with the closing of the Transaction, the convertible loan agreement with Beedie Capital dated July 28, 2022 (the " Loan Agreement ") will be amended to accommodate the assets of Millennial and its subsidiaries, each of which, following the closing of the Transaction, will be loan parties and provide guarantees and security for the obligations under the Loan Agreement. In addition, conditional on the closing of the Transaction, the Loan Agreement will be amended to, among other things, modify the conversion price on the initial advance of US$10 million under the Loan Agreement to reflect a 35% premium to the Issue Price (the " Initial Advance Conversion Price ") and to increase the effective interest rate from 8.75% to 9.25% per annum on the loan outstanding, which interest continues to be accrued for the first twenty-four (24) months from the date of the Loan Agreement, payable quarterly either in shares or in cash, at Integra's election. As of the date hereof, the principal amount of the loan outstanding under the Loan Agreement is US$20 million, of which US$10 million is currently drawn.

Beedie Capital has provided their consent for the Transaction, subject to, among other things, the satisfaction or waiver of certain conditions precedent by Integra, including the completion of the Brokered Offering and the Transaction in accordance with their respective terms, approval of the TSXV and the New York Stock Exchange for the revised Initial Advance Conversion Price and there being no other default or event of default under the Loan Agreement.

Consolidation

Subject to the completion of the Transaction and receipt of approval from the TSXV, Integra intends to consolidate the Integra Shares on the basis of one post-consolidation Integra Share for every 2.5 pre-consolidation Integra Shares (the " Consolidation "). It is expected that the Consolidation will take effect shortly following the completion of the Transaction.

Assuming the maximum number of Subscription Receipts are sold pursuant to the Brokered Offering (including pursuant to the Over-Allotment Option) and the Non-Brokered Offering, Integra expects to have approximately 177.1 million Integra Shares issued and outstanding immediately following the completion of the Transaction on a non-diluted basis and approximately 190.4 million Integra Shares outstanding on a fully-diluted basis. Following the implementation of the Consolidation, Integra will have approximately 70.8 million Integra Shares issued and outstanding on a non-diluted basis and approximately 76.2 million Integra Shares outstanding on a fully-diluted basis. No fractional Integra Shares will be issued, and any fractional interest in Integra Shares resulting from the Consolidation will be rounded down to the nearest whole Integra Share.

A letter of transmittal will be mailed to registered shareholders once the Consolidation has taken effect, which will contain instructions on how registered shareholders can exchange their share certificates or direct registration system advices (" DRS Advices "), evidencing their pre-Consolidation Integra Shares for new share certificates or DRS Advices representing the number of post-Consolidation Integra Shares to which they are entitled.
