Defiance Silver Receives Updated Drill Permit

for Victoria Copper Project, Sonora, Mexico

Vancouver, British Columbia--(Newsfile Corp. - February 26, 2026) - Defiance Silver Corp. (TSXV:

DEF) (FSE: D4E) (WKN: A1JQW5) ("Defiance" or the "Company") reports that the Secretariat of

Environment and Natural Resources of Mexico (SEMARNAT) has approved the Company's Informe

Preventivo, the environmental authorization required to conduct exploration drilling, for the Victoria target

at its Green Earth Project, located in Sonora, Mexico.

The Informe Preventivo was prepared and submitted in accordance with Mexican environmental

regulations and reflects Defiance's commitment to responsible exploration practices and environmental

stewardship. The approval authorizes a drilling permit valid for 36 months and includes permission for up

to 89 drill pads and the construction of new access roads, subject to compliance with the approved

environmental terms and conditions. The Company would like to acknowledge the SEMARNAT offices

and the collaborative efforts of the technical and environmental consultants for the efficient review

process.

"The Victoria copper project represents a rare opportunity to drill a large-scale copper-molybdenum

target with coincidental surface mineralization, widespread surface hydrothermal alteration and

prospective geophysics. This updated drill permit allows Defiance to move forward at the Victoria

project."

- Chris Wright, Executive Chairman & CEO, Defiance Silver
