Anomalous Rare Earth Elements in Smoky Quartz Samples within Quantum’s Quest Property
Vancouver, BC – August 1, 2025 – Quantum Critical Metals Corp. (TSX.V: LEAP | OTCQB: ATOXF | FSE: 86A1) (“Quantum” or the “Company”) is pleased to announce that it has completed additional research on its Quest critical mineral property which was acquired earlier this year to complement the Company’s growing strategic resource portfolio.
The mineral claim is in the Lake Chapiteau region of Québec and hosts a region of critical and rare earth elements in syenite granitic rocks. The highlights of the mapping and sampling program completed by former owners of the project were reported previously including notable anomalous values of barium, beryllium, fluorine, gallium, niobium, rubidium, tantalum, thorium, zinc and zirconium.
An anomalous sample was reported as collected within Quantum’s claim boundaries from a report on SIGEOM, the Québec geoscientific database. SIGEOM had recorded the sample as sedimentary rock, however upon review, the assessment report stated it was a hand selected sample of smoky quartz taken from an outcrop of quartziferous syenite with rapakivi texture, which is more likely the lithology for rare earth type mineralization. Quantum has staked an additional claim cell that adjoins the current one to expand the exploration potential for rare earth elements.
A historical sample (ID 205273) from within the claim boundaries contained 20% Total Rare Earth Elements (“TREE”), with 8.7% being light rare earth elements (“TLREE”) and 11.3% being total heavy rare earth elements (“THREE”). The sample also contained 226 gpt gallium, 78 gpt germanium and 15,060 gpt beryllium. The data reported in this release has been taken from historical exploration assessment reports. None of the historical information in this news release has been independently verified by the Company and should not be relied upon.
*Grab samples are discrete samples which are typically, but not exclusively, constrained to mineralization. Grab samples are selective in nature and collected to determine the presence or absence of mineralization and are not intended to be representative of the deposit in its entirety.
CEO Marcy Kiesman commented, “Quantum is continuing to unlock its portfolio of critical minerals and rare earth assets to power the next generation of high tech and defence industries. Domestic sources of yttrium, beryllium, neodymium and cesium are essential to help fill the growing global supply gap. Quantum continues to elevate its position to meet the growing global demand for critical and rare earth elements by stockpiling a portfolio of first-class assets with exciting historical assays.”
Next Steps
The Company is investigating a site visit in an effort to collect duplicate samples to confirm the assay results from previous work. Depending on access, the Company is also looking to potentially delineate the extent of the mineralization and take additional representative samples of the area.
Why This Project Matters
On April 4, 2025, China’s Ministry of Commerce implemented export restrictions on seven rare earth elements (REEs) and related magnets used in the defense, energy, and automotive industries, targeting samarium, gadolinium, terbium, dysprosium, lutetium, scandium, and yttrium. On June 11, 2025, U.S. and Chinese officials reached a new trade framework under which China agreed to resume supplying rare earth minerals and permanent magnets to the United States, while the U.S. will maintain a fixed 55% tariff on Chinese goods. The deal underscores the precariousness of Western supply chains and the strategic importance of domestic rare earth development.
About Rare Earth Elements
Rare Earth Elements (REEs) are a group of 17 chemically similar metallic elements essential in many modern technologies. Light REEs (LREEs) include La, Ce, Pr, Nd, Pm, and Sm and are more common in Earth’s crust. Heavy REEs (HREEs) include Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, Lu, and Y and are less abundant and harder to extract, with generally higher economic value, used in high-performance magnets, phosphors, lasers, and medical technology. Despite their name, most REEs are not rare in terms of crustal abundance, but they are rarely found in economically viable concentrations.
About Gallium
Gallium is a critical component in semiconductors, telecommunications, and renewable energy sectors. China has imposed export controls on gallium, exacerbating supply chain challenges for the U.S. and its allies.
About Critical Minerals
Critical minerals are essential components in modern technologies, including renewable energy systems, defense applications, and advanced electronics. The U.S. Geological Survey’s 2022 list includes 50 critical minerals, while Canada in 2024 has designated 34 minerals as critical. China has implemented export bans affecting the West, underscoring the importance of diversifying supply chains and developing domestic sources.
