TACTICAL RESOURCES SECURES 1.5M TONS OF CRUSHED AGGREGATE FEEDSTOCK IN TEXAS

Tactical Resources Corp. has entered into an asset purchase agreement (the APA) to acquire approximately 1.5 million tons of processed tailings from the Sierra Blanca Quarry (SBQ). Based on initial sampling and metallurgical testing, the crushed aggregate tailings materials appear to contain consistent REE mineralization and is expected to serve as potential near-term feedstock for the company's Peak rare-earth project.

The acquisition provides Tactical with secured feedstock material sourced from an active quarry operation, significantly reducing traditional mining and permitting timelines. By leveraging already extracted and stockpiled tailings, the company is positioning to accelerate development of a domestic rare-earth supply chain at a time of increasing United States demand and geopolitical urgency. The secured material is expected to support early stage construction and potential initial processing at the Peak project, representing a foundational step toward envisioned future revenue generation. Currently, there has been insufficient exploration to allow for an estimate of a mineral resource, nor have any such REE minerals been extracted on a commercial basis.

The acquisition represents a step in derisking the company's development pathway by securing feedstock material within an established industrial site. By leveraging existing tailings, Tactical is advancing a strategy designed to compress project timelines and reduce capital intensity relative to traditional rare-earth development, while supporting the buildout of a domestic U.S. supply chain amid increasing demand for critical minerals.

"This agreement moves us from access to ownership of a meaningful volume of potential feedstock," said Ranjeet Sundher, chief executive officer of Tactical Resources. "With approximately 1.5 million tons of material now secured, we are positioning the Peak project to advance without the delays typically associated with a new mine development. combined with our broader agreements at Sierra Blanca, this establishes a pathway from near-term feedstock to long-term asset ownership."

Transaction details

Pursuant to the APA, at closing, SBQ will sell, assign, transfer, convey and deliver to Tactical all of SBQ's right, title and interest in approximately 1.5 million tons of processed crushed aggregate feedstock currently stockpiled on the leased premises in Sierra Blanca, Tex. These assets represent accumulated byproduct material from SBQ's two-decade-long ballast crushing operations-material which based on initial sampling and metallurgical testing indicates elevated levels of rare-earth elements and constitutes potential feedstock for the company's planned rare-earth extraction facility. The consideration for the acquisition consists of approximately three million shares of common stock of PubCo (as defined below), to be issued at closing.

Closing of the APA is subject to, among other customary conditions, the completion of Tactical's previously announced business combination with Plum Acquisition Corp. III, which is expected to result in the listing of the resulting issuer's (PubCo) common shares on the Nasdaq Capital Market. The transaction has received shareholder approval from the shareholders of Tactical and the shareholders of Plum. In December, 2025, the registration statement on Form F-4 filed by Plum III Merger Corp. with the U.S. Securities and Exchange Commission became effective.

The company has not yet applied to the TSX Venture Exchange for review of the previously announced purchase and sale agreement (PSA), dated March 16, 2026, or the APA described herein. The company intends that all steps and transactions contemplated under the PSA and the APA will be completed only following the closing of the transaction and the Nasdaq listing. In the event that the company remains listed on the TSX-V at the time of any proposed closing under the PSA or the APA, the company will apply for and obtain TSX-V review and approval, as required, prior to completing any such transactions.

Building a scalable feedstock position

The APA builds on Tactical's previously announced PSA with SBQ and Dennis Walker and Becky Dean Walker, entered into on March 9, 2026, and announced on March 16, 2026. That agreement provides Tactical with: (i) an exclusive option, exercisable until five business days after the date that is 36 months following the fifth business day after Tactical's parent company is first listed on the Nasdaq Stock Market, to acquire 100 per cent of the membership interests of SBQ for a purchase price of $29-million (U.S.) (50-per-cent cash/50-per-cent equity) (the SBQ purchase price); (ii) access to approximately four million tons of tailings; and (iii) rights to additional tailings produced thereafter.

The APA announced today converts a portion of that access into secured ownership, representing the first tranche of feedstock within a broader, staged acquisition strategy.

Together, the APA and the PSA establish a multilayered position at Sierra Blanca -0 combining near-term feedstock availability with a defined pathway to full asset ownership. This approach is designed to support phased development of the Peak project, beginning with existing material and expanding over time as additional assets are secured and technical work advances.
