Quantum Critical to expand Victory to 1,444 hectares

Ms. Marcy Kiesman reports QUANTUM EXPANDS VICTORY ANTIMONY PROPERTY IN HAIDA GWAII, BC Quantum Critical Metals Corp. has submitted an application to increase the size of its Victory antimony property to a total 1,444 hectares, pending approval by B.C. Mineral Titles Online. The project is located on the west side of Graham Island in Haida Gwaii, British Columbia. About the Victory antimony project The Victory antimony project was initially discovered in 1988 by Newmont Exploration of Canada along a newly constructed logging road. A 1989 assessment report reported a chip sample of mineralized boulders assaying 11.8 per cent arsenic, 1.24 per cent antimony and 0.136 per cent mercury (Turner, 1989). Mineralization of the showing reported 5 per cent stibnite (antimony mineral) and was reported to be exposed over a width of 2.5 to three metres over a length of 10 to 12 metres. The occurrence is described as being a hydrothermal hot spring deposit type within the Middle Jurassic Yakoun group pyroclastic andesites, volcanic sediments and argillites, which appear to be similar to the showing reported by Armory Mining Corp., which is adjacent to its Riley Creek project, as announced on Nov. 11, 2024. Subject to approval, Quantum plans to initiate access development to the expanded property, followed by field programs, including verification of historical Minfile showings, geological mapping and outcrop sampling. Why the Victory property matters This expansion safeguards coverage of the historical showing, reinforcing Quantum's dedication to responsible exploration and the advancement of critical metal supply independence in Canada. Chief executive officer Marcy Kiesman stated: "Securing reliable sources of antimony is becoming more important than ever. By expanding the Victory property to cover to the known Minfile showing, we demonstrate our commitment to building a resilient, domestic supply chain for critical minerals." None of the historical information in the release has been verified yet by the company and should not be relied upon, as the occurrence information may not be indicative of the mineralization in the area. Melanie Mackay, PGeo, EGBC (Engineers and Geoscientists British Columbia) 35256, is a director and qualified person for Quantum, and approves the technical content of this news release. About antimony Antimony is a critical mineral primarily used as a flame retardant and alloying agent in lead-acid batteries, ammunition and semiconductors. It also has strategic applications in defence and energy storage technologies, making it a high-priority material for many governments. The global antimony market is forecasted to grow at a compound annual growth rate of 5.5 per cent from 2023 to 2030, driven by rising demand in renewable energy storage and military applications. China dominates global antimony production, accounting for over 70 per cent of supply, leading to significant supply chain risks. This concentration creates vulnerabilities for industries and countries reliant on antimony for essential applications. In December, 2024, China banned exports of antimony to the United States, citing its dual military and civilian uses, further exacerbating supply chain concerns. The U.S. Department of Defence has designated antimony as a critical mineral due to its importance in national security, and governments are prioritizing domestic production to mitigate supply chain disruptions. Antimony has been on the critical mineral list in Canada for a significant period of time. Projects exploring antimony sources in North America play a key role in addressing these challenges. About recent private placement The company would also like to announce in the recent offering, which closed for $2,009,100.30 in gross proceeds (see press release dated July 18, 2025), that a total of $54,217 in cash fees were paid as finders' fees, and 541,170 broker warrants were issued with terms being the same as the offering, being an exercise price of 20 cents for one common share of the company for a period of two years. About critical metals Critical metals are essential components in modern technologies, including renewable energy systems, defence applications and advanced electronics. Both the United States and Canada have identified specific lists of critical minerals vital to their economic and national security. The U.S. Geological Survey's 2022 list includes 50 critical minerals while Canada in 2024 has designated 34 minerals as critical. Recent geopolitical developments have heightened concerns over the supply chain security of these critical metals. China, which holds a dominant position in the production and processing of several critical minerals, has implemented export bans affecting the West. Notably, in December, 2024, China banned exports of gallium, germanium and antimony to the United States, citing their dual military and civilian uses. Following this, in February, 2025, China imposed extensive export controls on five additional strategic metals: tungsten, indium, bismuth, tellurium and molybdenum. These metals are essential for various industries, such as defence, clean energy and consumer electronics. These actions underscore the strategic importance of diversifying supply chains and developing domestic sources for critical metals to mitigate geopolitical risks and ensure the stability of essential industries. About Quantum Critical Metals Corp. Quantum Critical is a Canadian mineral exploration company focused on advancing critical metal projects that power next-generation technologies.
