Libra to Acquire Brion Minerals, Gaining Exposure to a Portfolio of Lithium and Other Energy Materials Projects in Brazil

Libra Energy Materials Inc. (CSE: LIBR) (FSE: W0R0) ("Libra" or the "Company") is pleased to announce that it has entered into a definitive share exchange agreement dated September 8, 2025 (the "Agreement"), to acquire 100% of the issued and outstanding shares of Brion Minerals Inc. ("Brion"), a Cayman Islands domiciled company and portfolio company of Frontera Minerals Inc. ("Frontera"), a Brazilian focused critical minerals investment, exploration and development group (the "Acquisition").

The Acquisition, once completed, will provide Libra with a 100% interest in a diverse portfolio of critical minerals projects in Brazil, including twenty-one hard-rock lithium projects, eight graphite projects, and one cobalt-nickel project. These thirty projects together span approximately 30,706 hectares of highly prospective ground in multiple emerging critical minerals hubs across Brazil.

Transaction Overview

Under the terms of the Agreement, Libra will acquire all of the issued outstanding shares of Brion, resulting in Brion becoming a wholly-owned subsidiary of Libra. In consideration for the Acquisition, Libra will issue an aggregate of four million (4,000,000) Libra common shares (the "Consideration Shares") to Brion's shareholders at a deemed price of CAD$0.30 per Consideration Share. Additionally, the Brion shareholders shall be entitled to a milestone payment of US$1,500,000, payable in cash or Libra common shares at Libra's discretion, should Libra announce a preliminary economic assessment by December 31, 2030, demonstrating a project net present value exceeding US$100 million on any mineral project located in Brazil controlled by Libra.

The Consideration Shares are subject to the following contractual restrictions on transfer:

• 1,075,000 of the Consideration Shares shall be released on the date that is 4 months from Closing (as defined below);
• 537,500 of the Consideration Shares shall be released on the date that is 12 months from Closing;
• 537,500 of the Consideration Shares shall be released on the date that is 18 months from Closing; and
• 1,850,00 Consideration Shares shall be subject to a lock-up agreement on substantially identical terms as Libra's founders' voluntary pooling agreement dated as of December 31, 2024, pursuant to which an aggregate of 26,040,799 existing Libra common shares, which at Closing is expected to represent approximately 45% of the Company's then issued and outstanding common shares, are held in contractual escrow and are restricted from trading until the date upon which (i) there is a change of control of Libra; or (ii) such founders have unanimously agreed in writing to such release.

The Acquisition is expected to close on or before September 30, 2025 ("Closing"), subject to customary regulatory approvals, including the approval of the Canadian Securities Exchange (the "CSE"), and closing conditions. The Agreement represents an arm's length transaction of the Company, with no finder fees nor any fee nor commission payable.

Strategic Benefits to Libra

While the assets of the Acquisition are not considered material properties (individually or taken as a whole) to the Company at this time, the Acquisition significantly enhances Libra's growth strategy and strengthens its position in the global critical minerals market. Key benefits include:

• Exposure to an Emerging Critical Minerals Hub: The projects are located in Brazil's emerging critical minerals districts, including Pernambuco, Rio Grande do Norte, Paraíba, Bahia, Tocantins, and Minas Gerais.
• Energy Materials Diversification: The portfolio includes potential lithium, graphite, and nickel-cobalt, positioning Libra to supply critical materials for batteries, electric vehicles (EVs), and renewable energy technologies.
• Geographic Diversification: The addition of these Brazilian assets diversifies Libra's exploration portfolio across multiple countries, expanding its global footprint, and provides access to a new source of capital in Latin America.
• Accretive, Low-Cost Acquisition: The share-based transaction allows Libra to acquire a diverse portfolio of untested lithium showings with minimal dilution, while conserving cash.
• Significant Exploration Upside: The portfolio includes projects that Libra considers highly prospective, with favourable surface geology that remains untested through drilling, offering indications for new discoveries.
• Alignment with Key Shareholders: The transaction aligns Libra with key local shareholders, including Brion's principal shareholder, Frontera Minerals, a Brazilian resource focused investment and development firm with extensive local expertise and a proven track record of several mineral discoveries, developments and mine builds in Brazil over the past fifteen years, enhancing Libra's operational execution abilities in Brazil.
• Year-Round Exploration: Brazil's favorable climate enables year-round prospecting, providing a better cadence of news flow compared to Canada, where fieldwork is largely limited to summers.

"Since going public in July 2025, we have continued to execute our strategy of consolidating the lithium space through bottom-market M&A, positioning Libra to potentially become a significant contributor in the battery materials supply chain," said Koby Kushner, CEO of Libra. "The acquisition of Brion's diverse portfolio in Brazil, a proven jurisdiction where Sigma Lithium advanced from maiden resource to production in under five years despite COVID, underscores the low-cost operating environment and efficient permitting timelines that offer unique advantages within our overall portfolio. This strategic move enhances our exposure to lithium, and introduces graphite and cobalt into the mix, aligning with the global push for sustainable energy solutions."

Asset Summary

• Lithium: Brion's portfolio encompasses multiple potential lithium mineral tenements totaling ~23,000 hectares across Minas Gerais, Rio Grande do Norte, Paraíba and Pernambuco, including:
  • Penelope: A high-potential lithium - niobium - tantalum project in Minas Gerais, with top sampling results of 110 parts per million ("ppm") Li (lithium), 8,780 ppm Nb (niobium), and 10,900 ppm Ta (tantalum). Identified pegmatite bodies, extend up to 700 meters ("m") in strike with widths of 25-50 m.
  • Lajes: Noted minerals include spodumene and columbite. Pegmatites, such as Pegm 03, extend over 1.1 kilometers ("km") in strike with widths up to 20 m.
  • Lajes Pintadas: Pegmatites, spanning over 1.1 km in strike with widths around 10 m with surface samples up to 139 ppm Ta, 50 ppm Li, 88 ppm Cs , and 453 ppm Nb.
  • São Mamede: Grab samples up to of 245 ppm Nb and 526 ppm Rb. Pegmatite bodies extending over 500-600 m in strike with widths of 4-5 m, containing scheelite, beryl, and columbite.

• Graphite (Limeira and Jordania): Located in South Bahia, home to over 80 years of continued graphite production with six active mines in production. High-grade graphite samples at Limeira, up to 7.22% graphitic carbon ("Cg") with large jumbo flakes, and channel samples of 1.56% Cg over 18 m. Mineralization at Jordania confirmed at surface, with grab sample results reaching up to 19.8% Cg.

Next Steps & Additional Board Member

Libra personnel are currently conducting a site tour across Brion's lithium assets Borborema, with the goal of designing an upcoming exploration program, including geological mapping, sampling, and geophysical surveys, to prioritize targets for future drilling. Further details on the exploration strategy, and initial findings on the newly acquired assets, will be announced in the coming months. Additionally, Libra will be appointing a representative of the Brion shareholders to its board of directors upon Closing, subject to regulatory and CSE approvals.
