QUANTUM REPORTS ZINC AT PROPHECY PROPERTY IN NORTHERN B.C.

Quantum Critical Metals Corp. has released the assay results of a site visit undertaken by the Quantum exploration team on its wholly owned Prophecy zinc prospect.

The Prophecy claims consist of seven mineral tenures totalling 4,349 hectares. All claims are located approximately 240 kilometres northwest of Fort St. John, B.C. The Prophecy property region has been explored since the early 1970s and was optioned by Cominco 1972 to 1973 who completed geological mapping, soil geochemistry, geophysics and drilling. Historic drill hole logs are available which show several intersections of lead and zinc mineralization; however, assays are not available.

The mineralization of the Prophecy claim region is associated with Mississippi Valley-type (MVT) vein systems. In late 2025, an airborne site visit was undertaken by Quantum, and 16 samples were collected from rock outcrop and float locations. Eight samples returned anomalous zinc results from assays as per Table 1, which indicates the samples associated with anomalous zinc results (ranging from 1,820 parts per million to 22,000 ppm Zn). Anomalous lead ranged from 63 ppm to 5,930 ppm Pb (lead) in the same samples with elevated zinc. As per Table 1, barium (Ba) assays returned 27 to 26,900 ppm and strontium (Sr) returned elevated levels from 58 to 5,910 ppm.

Elevated barium and strontium values associated with anomalous zinc and lead assays are consistent with Mississippi Valley-type (MVT) mineralization. The strong Ba-Sr association possibly reflects barite-bearing hydrothermal fluids and interaction with carbonate host rocks, supporting the interpretation of a basin-brine sourced mineralizing system. The association of the barium and strontium values in addition to the zinc and lead strongly support a MVT-style mineralizing environment rather than isolated zinc enrichment. This is important, as the geochemical signature shares characteristics with the Pine Point, NWT style MVT system, particularly the association of zinc-lead mineralization with elevated barium and strontium values which point to indicators of saline hydrothermal fluid activity.

Quantum's chief executive officer, Marcy Kiesman, stated: "For a preliminary site access visit at the Prophecy project we are very happy with the results of our grab samples. The claims were initially staked to explore the potential of germanium within the zinc minerals -- to align with Canada's strategic mineral list. To have assays returning up to 2.2 per cent zinc from surface on the first look at Prophecy is incredible."

Quantum is currently planning follow-up work on the project to include substantive mapping, sampling and prospecting of the claims with a particular focus on the areas with the historical B.C. MTO Minfile showings.

About zinc

Zinc (Zn) is widely used in industry because of its ease to work with, price point and corrosion resistance. Main uses consist of coating steel and/or iron to prevent rust, and making alloys (brass), batteries, chemicals and materials, and it is also an essential nutrient for humans and animals. Zinc is considered a strategic or critical metal in both Canada and the United States as it is essential for infrastructure (such as bridges, buildings and rail), industry (electronics, energy storage, batteries) and national security (protective coatings on ships and equipment, ammunition).

Assay QA/QC (quality assurance/quality control)

The samples were sampled from outcrop and float locations. Because these samples are technically grab samples they are selective by nature and may not represent the mineralization at depth. The samples were sent to AGAT Laboratories in Calgary. AGAT is certified and licensed for a number of tests and is ISO 9001:2015 and Standards Council of Canada accredited for mineral analysis, chemical/physical testing. The samples underwent sodium peroxide fusion with ICP-OES and ICP-MS finish.
