Item 8.01 Other Events.




Domestic Issuer Status

Perpetua Resources Corp. (the "Company") has determined that it no longer qualifies as a "foreign private issuer" as such term is defined in Rule 405 under the United States Securities Act of 1933 (the "Exchange Act"). As a result, effective January 1, 2022, the Company is required to, among other things, (i) file periodic reports and registration statements on U.S. domestic issuer forms with the Securities and Exchange Commission (the "SEC") and (ii) comply with U.S. proxy requirements with respect to solicitation materials, including those relating to the Company's 2022 annual meeting of shareholders.





Technical Report Summary

In connection with the Company's transition to U.S. domestic reporting under the Exchange Act, the Company is filing this Current Report on Form 8-K to provide its inaugural Technical Report Summary (the "TRS"), dated as of December 31, 2021, developed for the Stibnite Gold Project in accordance with the mining property disclosure rules specified in Subpart 1300 of Regulation S-K ("Subpart 1300") promulgated by the SEC. A copy of the TRS is filed as Exhibit 96.1 to this Current Report on Form 8-K and is incorporated herein by reference.

The TRS summarizes, in accordance with the mining property disclosure rules specified in Subpart 1300, the Company's 2020 Feasibility Study Technical Report, effective date December 22, 2020 and issue date January 27, 2021 (the "2020 FS"), which was completed under Canadian Securities Administrators National Instrument 43-101 guidelines ("NI 43-101"), with the following notable differences between the 2020 FS and the TRS:

· The TRS Mineral Resource estimates were developed based on a gold price of

$1,500/oz versus the $1,250/oz gold price assumed for the 2020 FS. The change
   in gold price results from higher trailing average gold prices at the date of
   preparation for the respective reports.

· The Measured Mineral Resources in the 2020 FS were reclassified to Indicated


   Mineral Resources in the TRS due to differences in Subpart 1300 versus NI
   43-101 Mineral Resources classification guidelines.

· The Proven Mineral Reserves from the 2020 FS were reclassified as Probable


   Mineral Reserves for the TRS resulting from the reclassification of the
   Measured Mineral Resources to Indicated Mineral Resources due to differences in
   Subpart 1300 versus NI 43-101 Mineral Resources classification guidelines.

· The TRS is classified as a Preliminary Feasibility level study whereas the 2020


   FS was classified as a Feasibility level study. This change was driven by the
   Subpart 1300 requirement that a compliant Feasibility level TRS include a
   capital cost contingency allowance no greater than 10%, whereas the initial
   capital cost estimate for the 2020 FS included a more conservative allowance at
   approximately 15%.

All other technical analyses, design information, capital and operating cost information, economic analyses, permitting and legal assumptions, conclusions and recommendations are consistent between the TRS and the 2020 FS.

The foregoing description of the TRS does not purport to be complete and is subject to, and qualified in its entirety by, the full text of the TRS attached hereto as Exhibit 96.1. The foregoing description of the 2020 FS does not purport to be complete and is subject to, and qualified in its entirety by, the full text of the 2020 FS, which was filed electronically on January 28, 2020 on SEDAR, and is publicly available online at www.sedar.com and www.perpetuaresources.com.
