Defiance Silver Files Technical Report for Its

Zacatecas Project

Vancouver, British Columbia--(Newsfile Corp. - December 17, 2024) - Defiance Silver Corp. (TSXV:

DEF) (FSE: D4E) (WKN: A1JQW5) ("

Defiance

" or the "

Company

") announces that, further to its news

releases dated

February 2, 2024

,

April 10, 2024

and

November 29, 2024

, relating to a continuous

disclosure review of the Company by the British Columbia Securities Commission (the "

BCSC

"), it has

filed a new technical report on the Company's Zacatecas Project in Mexico (which includes the San

Acacio project).

As reported in its

November 29

th

news release

, Defiance has been working with SGS Geological

Services, who had been contracted to prepare a revised technical report that would include all projects

forming part of the overall Zacatecas complex. The revised technical report includes all exploration work

completed on the project to date.

A mineral resource estimate was disclosed for the San Acacio project in a 2014 technical report.

However, as indicated in the

February 2, 2024

news release, the 2014 report did not comply with

disclosure requirements for mineral resources set out in NI 43-101 -

Standards of Disclosure for Mineral

Projects

("

NI 43-101

").

Defiance has completed additional diamond drilling on the project since 2014, including 73 drill holes for

a total of 26,578.03 metres on the San Acacio project, as well as extensive surface geological and

structural mapping of the mineralized zones, and surface soil sampling of the entire project. This work

has not yet been incorporated into current geological and resource models for use in the preparation of a

current mineral resource estimate by an independent qualified person.

Since the 2014 Mineral Resource Estimate on the San Acacio project ("

MRE

") did not comply with

disclosure requirements for mineral resources set out in NI 43-101, and the additional drilling completed

on the project has not yet been incorporated into current geological and resource models for use in the

preparation of a current mineral resource estimate by an independent qualified person, there are no

current mineral resources on the project.

Benjamin Eggers, P.Geo. and Sarah Dean, P.Geo. of SGS Geological Services, both qualified persons

under NI 43-101, have completed a technical report titled "

Technical Report for the Zacatecas Project,

Zacatecas, Mexico

" dated December 16, 2024 with an effective date of October 1, 2024. The technical
