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% arsenic, 1.24% antimony, and 0.136% mercury (Turner, 1989). Mineralization of the showing reported 5% stibnite (antimony mineral) and was reported to be exposed over a width of 2.5-3 metres over a length of 10-12 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 appears to be similar to the showing reported by Armory Mining Corp. which is adjacent to their Riley Creek project, as announced on November 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. CEO 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.

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 defense 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 (CAGR) of 5.5% from 2023 to 2030, driven by rising demand in renewable energy storage and military applications.
China dominates global antimony production, accounting for over 70% 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 Defense has designated antimony as a critical mineral due to its importance in national security, and governments are now 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 $2,009,100.30 in gross proceeds (see press release dated July 18, 2025) that a total of $54,217 cash fees were paid as finders’ fees and 541,170 broker warrants were issued with terms the same as the offering, being an exercise price of $0.20 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, defense 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 defense, clean energy, and consumer electronics.
These actions underscore the strategic importance of diversifying supply chains and developing domestic sources for critical metals to mitigate geo-political risks and ensure the stability of essential industries.
