Vancouver, British Columbia--(Newsfile Corp. - September 22, 2026) - Krait Critical Minerals Corp. (CSE: KRIT) (FSE: U0S) (the "Company" or "Krait") is pleased to announce that it has engaged Rangefront Mining Services ("Rangefront"), an Elko, Nevada-based geological services firm, to undertake a detailed geological mapping, sampling and exploration targeting program at the Bales Antimony Project in Okanogan County, Washington.

The engagement represents an important step in Krait's technical evaluation of the Bales Antimony Project following the Company's acquisition of Nevada Hills Antimony LLC ("Nevada Hills"). Through Nevada Hills, Krait holds contractual interests relating to the Bales Antimony Project, together with direct interests in the Antimony Bell Project (collectively, the "Antimony Projects") and other related assets in Washington State.

Oscar Mendoza, Chief Executive Officer and Director of Krait, commented: "Engaging Rangefront is an important step in bringing a systematic, modern exploration approach to the Antimony Projects. The historical work gives us a starting point, but our objective is to get geologists on the ground, verify what is there, understand the structural and geological controls on mineralization and begin converting that information into clearly defined exploration targets."

"This program is designed to give us the geological foundation we need to make disciplined decisions about the next stage of exploration. If the field work supports our geological thesis, we expect the resulting mapping, sampling and structural data to play an important role in defining priority targets for potential drilling," added Mendoza.

Rangefront Geological Program

Rangefront's proposed field program is designed to improve Krait's understanding of the geological and structural controls associated with antimony and related mineralization and to establish priority areas for follow-up exploration and potential drilling.

The planned work includes:

• Detailed geological mapping of intrusive-carbonate contacts and associated skarn zoning, including garnet-epidote-scheelite assemblages;

• Underground and surface verification of historical mineralized zones, including accessible workings and historical mine dumps;

• Systematic geological mapping and sampling across priority areas;

• Structural measurements intended to better constrain the orientation, plunge and geological controls of mineralized zones; and

• Development of early-stage priority drill targets, including target coordinates, geological sections and preliminary drill-collar concepts.

Upon completion of the program, Rangefront is expected to provide Krait with geological data in digital formats, relevant supporting datasets and a report summarizing the work completed and its geological conclusions.

The proposed program provides for approximately seven days of fieldwork involving a mapping geologist and a junior geologist and contemplates approximately 100 assays as part of the exploration work.

Building a Modern Geological Model

The objective of the program is to move beyond the historical exploration record and begin developing a modern geological framework for the Antimony Projects.

Particular emphasis will be placed on understanding the relationship between historical mineralized zones, intrusive contacts, alteration, structural controls and surface expressions of mineralization. The resulting geological model is expected to assist Krait in prioritizing areas for additional exploration and identifying potential targets for a future drill program.

Next Steps

Subject to applicable property access and other required conditions, Krait intends to use the results of the Rangefront program to establish priorities for subsequent exploration at the Antimony Projects.

The Company expects the initial technical work to integrate historical information with new geological observations, structural data and analytical results. Following receipt and interpretation of the field data and assay results, Krait will evaluate potential follow-up programs, which may include additional geological mapping and sampling, structural work, refinement of priority drill targets and, if warranted, drilling.

National BNN Bloomberg Campaign Launch

The Company has engaged Greenshoe Media Group Inc. ("Greenshoe"), an arm's-length media production and advertising company based in Maple, Ontario, to produce and execute a national television advertising campaign on BNN Bloomberg. The 12-week campaign will include two 30-second television commercials and a 120-second stock ticker sponsorship. The Company will pay Greenshoe C$44,900, plus applicable taxes, for the media production and airtime campaign. Greenshoe does not provide investor relations services to the Company. Greenshoe can be contacted at 10933 Jane Street, Maple, Ontario L6A 1S1, by telephone at 416.488.9663 or by email at info@gsmg.ca
