Vancouver, British Columbia--(Newsfile Corp. - February 2, 2024) - Defiance Silver Corp. (TSXV: DEF) (FSE: D4E) (WKN: A1JQW5) ("Defiance" or the "Company") announces that, as a result of a continuous disclosure review by the British Columbia Securities Commission, the Company is issuing the following news release to clarify its disclosure as it pertains to its technical reports entitled "NI 43-101 Technical Report Preliminary Economic Assessment on the Tepal Project, Michoacán, Mexico" dated February 24, 2017 with an effective date of January 19, 2017 on the Tepal project (the "Tepal Report") and its technical report entitled "Technical Report and Resource Estimate, San Acacio Silver Deposit, Zacatecas State, Mexico" dated September 26, 2014 with an effective date of April 1, 2014 on the San Acacio project (the "San Acacio Report", and together with the Tepal Report the "Technical Reports").

In order to address these deficiencies under National Instrument 43- 101 - Standards of Disclosure for Mineral Projects ("NI 43-101"), the Company understands it will need to amend the Technical Reports accordingly. On the Tepal project, as some of the authors of the Tepal Report are no longer Qualified Persons under NI 43-101 due to notably, retirement, the Company is presently working with its technical advisors who participated in the preparation of the Tepal Report on (i) a feasible timeline to complete an amended report and (ii) identifying new Qualified Persons to take on responsibility for the relevant chapters of the Tepal Report in connection with the amended report. The Company is working to file an amended technical report as soon as possible. The Company will provide regular updates in connection with the preparation and filing of the amended technical report for its Tepal project.

As for the San Acacio Report, the Company is incapable of preparing an amended report for reasons beyond its control. Indeed, the authors of the San Acacio Report were independent consultants and are no longer Qualified Persons under NI 43-101 due to notably, retirement. In light of this regrettable situation, Defiance will be working with new technical advisors to prepare a new technical report that will replace the current San Acacio Report. The Company expects to file this new technical report by the end of March 2024. The Company will provide regular updates in connection with the preparation and filing of this new report for its San Acacio project.

At the present time, in light of the current situation, the Company advises that the information relating to its projects contained in the Technical Reports should not be relied upon as they are not supported by compliant technical reports under NI 43-101.

Further, and separate from the Tepal Report and the San Acacio Report addressed above, the Company is also currently updating and clarifying additional disclosure contained on its website and in its corporate presentation.
