Integra Resources Corp. (TSX-V: ITR) (NYSE American: ITRG) and Millennial Precious Metals Corp. (TSX-V: MPM) (OTCQB: MLPMF) are pleased to announce that they have entered into an arm’s length definitive agreement dated February 26, 2023 for an at-market merger  pursuant to which Integra and Millennial have agreed to combine their respective companies 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 for each Millennial common share held. 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 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 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) 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. 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.”

Benefits to Integra and Millennial Shareholders

• Enhanced Scale & Diversification: Combined portfolio contains three of the top oxide heap leach gold-silver projects in the USA not currently controlled by a major and creates a foundation for building a new, Great Basin focused, precious metals producer.
• Strong Balance Sheet to Advance Projects: The combined company will have a significantly strengthened balance sheet allowing for meaningful advancement of key milestones at DeLamar, Wildcat and Mountain View.
• Improved Capital Markets Presence: Enhanced institutional investor following, increased size and trading liquidity in both Canada and the USA, along with a strong equity research following.
• Greater Potential for Value Creation: Combination of DeLamar, Wildcat and Mountain View with a sequenced development strategy is expected to result in greater value creation for shareholders of Integra and Millennial that would not be possible on a standalone basis, balancing execution risks between three projects.
• Wheaton Partnership: Strategic equity partnership with Wheaton provides transaction and project validation and creates a pathway to project financing with one of the industry’s leaders.

Management Team and Board of Directors

The combined company’s board of directors will be led by George Salamis as Executive Chairman and will be comprised of six board members nominated by Integra and three board members nominated Millennial. Apart from his duties as Executive Chairman, Mr. Salamis will be focusing his efforts executing on permitting and advanced feasibility studies on the combined company’s flagship DeLamar gold-silver deposit in Idaho.
