Tactical Resources, a Growing North American Rare Earth Elements Company, to List on NASDAQ

• Tactical Resources' mission is to become America's next producer of Rare Earth Elements (REEs), the critical materials needed in the development of modern technologies with uses in semiconductors, electric vehicles, advanced robotics, and most importantly, national defense.
• The proposed business combination with Plum Acquisition Corp. III implies a pro forma enterprise value of $589 million.
• With China currently producing nearly 70% of the world's REEs, Tactical Resources' role as one of only a few near-term U.S.-focused REEs developers creates an opportunity to deliver value in strengthening both domestic supply chains and national security.
• Tactical Resources' Peak Project has the exclusive rights to acquire REEs enriched tailings and stockpiled materials from the Sierra Blanca Quarry (SBQ). The Peak Project has access to an existing advanced permitted and operational mine in Texas with proven REEs enriched tailings already extracted, and one of only a few rare earth hard rock Direct-Leach-Extractable projects in the world.
• Transaction proceeds will support Tactical Resources' strategic growth plan, which includes helping finance Tactical Resources' operations plan at the Peak Project and the progression of Tactical Resources' future production activities.

Tactical Resources Corp. (TSX.V: RARE | OTC: USREF) ("Tactical Resources" or the "Company"), a mineral exploration and development company, and Plum Acquisition Corp. III (NASDAQ: PLMJ) ("Plum"), a NASDAQ-listed special purpose acquisition company, today announced they have entered into a definitive business combination agreement (the "Business Combination Agreement").

The Company's flagship asset, the Peak Project ("Peak Project") contains the rights to acquire REEs enriched tailings and stockpiled materials extracted from the Sierra Blanca Quarry ("SBQ"). The Peak Project is a rare earth focused project strategically located southeast of El Paso, Texas. This convenient location in a mining-friendly jurisdiction offers extensive infrastructure, including easy highway, power, water, and rail line access. Tactical Resources believes that the Peak Project will enable it to become a significant REEs producer in the United States.

The Peak Project is one of only a few rare earth hard rock Direct-Leach-Extractable projects in the world, with initial quarry operating permits already in place. The Company also has an exclusive option to purchase SBQ's mining lease and associated infrastructure for the Peak Project.

With China currently producing nearly 70% of the world's REEs and demand for REEs continuing to grow, North America continues to look outside China to deliver supply of REEs. Tactical Resources is focused on supplying a range of REEs to the U.S. market to support the development of modern technologies with uses in semiconductors, electric vehicles, advanced robotics, and most importantly, national defense.

Key Investment Highlights

• Growing Rare Earth Elements (REEs) Mining Asset and Company - strong position with geographic focus in the U.S.
• Significant Geo-Political and Supply Implications - enabling reduced dependence on China for REEs critically needed for semiconductors, electric vehicles, advanced robotics, and most importantly, national defense.
• Existing Operational Mine in Texas with Proven REEs Enriched Tailings Already Extracted -- demonstrated testing results showcases potential future success.
• Strong and Compelling Financial Upside - based on established precedents and low initial capital expenditures to get to initial production.
• Dedicated Management Team with Proven Track Record - deep industry experience and substantial sector expertise.

Management Commentary

Ranjeet Sundher, CEO of Tactical Resources, commented: "Today represents a significant day and an exciting milestone for Tactical Resources. We believe that this business combination with Plum will enable us to advance our growth strategy and form strategic alliances that enhance shareholder value. Tactical Resources intends to use the capital raised to transform both domestic and international rare earth element supply chains and lessen America's reliance on overseas critical mineral resources. While others may be focusing on the manufacturing of singular end-products such as magnets, our focus is on the more critical raw ingredients needed to fuel the overarching rare earth elements ecosystem. Given the advanced infrastructure nearby our project, what sets us apart is that we believe we won't need the billions of dollars and decades of time typically needed in the mining industry to put our project into production. We believe that this business combination will help position Tactical Resources to become a significant rare earth elements producer in the United States."

Kanishka Roy, CEO of Plum, added: "We are thrilled to announce our business combination with Tactical Resources. At Plum, we are committed to partnering with companies with strong business profiles and experienced management teams, and Tactical Resources stood out to us due to a compelling history of successes achieved by members of its management team and a very important mission to enhance national security. With the U.S.'s reliance on Chinese rare earth element sources, we believe that Tactical Resources is poised to play a critical role in supply chains essential to semiconductors, a clean energy future, and the national defense industry. We look forward to collaborating with Tactical Resources, Ranjeet and his team, as Tactical Resources grows and works to create shareholder value."

Proposed Business Combination Overview

The Proposed Business Combination implies a pro forma enterprise value of $589 million, assuming Tactical Resources is delivered on a cash free, debt free basis. The proceeds of the Proposed Business Combination will support Tactical Resources' strategic growth plan, which includes helping finance Tactical Resources' operations plan at the Peak Project and the progression of Tactical Resources' future production activities.

Pursuant to the Business Combination Agreement, Plum, a Cayman Islands exempted company, will re-domicile in the Province of British Columbia, Canada and amalgamate with a newly formed company incorporating under the laws of the Province of British Columbia ("Pubco") to form one corporate entity ("New Pubco"). A newly formed, wholly-owned subsidiary of Plum incorporated under the laws of the Province of British Columbia ("Amalco") will amalgamate with the Company to form one corporate entity, such that, following the amalgamation, the Company will continue as a wholly-owned subsidiary of New Pubco, which will be renamed "Tactical Resources Corp." or such other name as may be agreed to between the parties. The aggregate transaction consideration deliverable to the Company's shareholders will be a number of newly issued common shares of New Pubco based on a $500 million pre-transaction equity value of the Company.

The Proposed Business Combination has been unanimously approved by the board of directors of Plum and by the disinterested directors of the board of directors of the Company. The Proposed Business Combination is expected to be completed in the fourth quarter of 2024, subject to customary closing conditions, including all requisite approvals by shareholders of Plum and Tactical Resources, the listing approval of Nasdaq Stock Market, the effectiveness of the registration statement on Form F-4 to be filed by New Pubco with the U.S. Securities and Exchange Commission ("SEC") in connection with the Proposed Business Combination (the "Registration Statement"), and satisfaction or waiver of the other conditions set forth in the Business Combination Agreement. The Company is expected to delist from the TSX Venture Exchange upon closing of the Proposed Business Combination.

Under the terms of the Business Combination Agreement, Tactical Resources' existing shareholders will convert 100% of their equity/ownership stakes into New Pubco and are expected to own approximately 82% of New Pubco upon consummation of the Proposed Business Combination.
