REGISTRATION OF ADDITIONAL SECURITIES

This Registration Statement registers the offer and sale of an additional 4,000,000 common shares, no par value (the “Common Shares”) of Perpetua Resources Corp. (the “Company”), pursuant to the Company’s Omnibus Equity Incentive Plan, as amended by the First Amendment to the Omnibus Equity Incentive Plan (as amended, the “Plan”). The additional Common Shares covered by this Registration Statement were approved for issuance by the Company’s shareholders at the Company’s Annual General Meeting of Shareholders held on May 16, 2024. The Company has previously filed a registration statement on Form S-8 with respect to the Common Shares originally authorized for issuance prior to the approval of the amendment to the Plan. Accordingly, pursuant to General Instruction E to Form S-8, the contents of the earlier registration statement on Form S-8 filed with the U.S. Securities and Exchange Commission on June 9, 2021 (Registration Number 333-256925) are incorporated herein by reference and made part of this Registration Statement, except as modified hereby.

PART II

INFORMATION REQUIRED IN THE REGISTRATION STATEMENT

Item 3. Incorporation of Documents by Reference.

The following documents filed by the Registrant with the Commission pursuant to the Securities Exchange Act of 1934, as amended (the “Exchange Act”), are incorporated into this registration statement by reference:

All reports and other documents subsequently filed by the registrant pursuant to Sections 13(a), 13(c), 14 and 15(d) of the Exchange Act, prior to the filing of a post-effective amendment to this Registration Statement that indicates that all of the shares of Common Stock offered under this Registration Statement have been sold or that deregisters all of such shares of Common Stock then remaining unsold, shall be deemed to be incorporated by reference in this Registration Statement and to be a part hereof from the date of the filing of such report or other document. Any statement contained herein or in any report or other document incorporated or deemed to be incorporated by reference herein shall be deemed to be modified or superseded for purposes of this Registration Statement to the extent that the statement contained herein or therein, or in any report or other document forming any part of the Section 10(a) prospectus to be delivered to participants in connection herewith, modifies or supersedes such statement. Any statement so modified or superseded shall not be deemed, except as so modified or superseded, to constitute a part of this Registration Statement.

Item 6. Indemnification of Directors and Officers.

We are incorporated under the BCBCA and are subject to the provisions of Part 5, Division 5 of the BCBCA. Under Section 160 of the BCBCA, we may, subject to Section 163 of the BCBCA:

and including, subject to certain limited exceptions, the heirs and personal or other legal representatives of that individual (collectively, an “eligible party”), against all eligible penalties to which the eligible party is or may be liable; and

Under Section 161 of the BCBCA, and subject to Section 163 of the BCBCA, we must, after the final disposition of an eligible proceeding, pay the expenses actually and reasonably incurred by an eligible party in respect of that proceeding if the eligible party (a) has not been reimbursed for those expenses, and (b) is wholly successful, on the merits or otherwise, in the outcome of the proceeding or is substantially successful on the merits in the outcome of the proceeding.

Under Section 162 of the BCBCA, and subject to Section 163 of the BCBCA, we may pay, as they are incurred in advance of the final disposition of an eligible proceeding, the expenses actually and reasonably incurred by an eligible party in respect of the proceeding, provided that we must not make such payments unless we first receive from the eligible party a written undertaking that, if it is ultimately determined that the payment of expenses is prohibited under Section 163 of the BCBCA, the eligible party will repay the amounts advanced.

Under Section 163 of the BCBCA, we must not indemnify an eligible party against eligible penalties to which the eligible party is or may be liable under Section 160(a) of the BCBCA, or pay the expenses of an eligible party in respect of that proceeding under Sections 160(b), 161 or 162 of the BCBCA, as the case may be, if any of the following circumstances apply:

If an eligible proceeding is brought against an eligible party by or on behalf of our company or by or on behalf of an associated corporation, we must not either indemnify the eligible party against eligible penalties to which the eligible party is or may be liable under Section 160(a) of the BCBCA, or pay the expenses of the eligible party under Sections 160(b), 161 or 162 of the BCBCA, as the case may be, in respect of the proceeding.

Under Section 164 of the BCBCA, and despite any other provision of Part 5, Division 5 of the BCBCA and whether or not payment of expenses or indemnification has been sought, authorized or declined under Part 5, Division 5 of the BCBCA, on application of our company or an eligible party, the Supreme Court of British Columbia may do one or more of the following:

Section 165 of the BCBCA provides that we may purchase and maintain insurance for the benefit of an eligible party or the heirs and personal or other legal representatives of the eligible party against any liability that may be incurred by reason of the eligible party being or having been a director or officer of, or holding or having held a position equivalent to that of a director or officer of, our company or an associated corporation.

Under our Articles, and subject to the BCBCA, we must indemnify a director, former director or alternate director and his or her heirs and legal personal representatives against all eligible penalties to which such person is or may be liable, and we must, after the final disposition of an eligible proceeding, pay the expenses actually and reasonably incurred by such person in respect of that proceeding. Each director and alternate director is deemed to have contracted with our company on the terms of the indemnity contained in our Articles.

Under our Articles, and subject to the BCBCA, we may agree to indemnify and may indemnify any person (including an eligible party). We have entered into indemnity agreements with certain of our directors and officers.

Pursuant to our Articles, the failure of an eligible party to comply with the BCBCA or our Articles does not, of itself, invalidate any indemnity to which he or she is entitled under our Articles.

Under our Articles, we may purchase and maintain insurance for the benefit of a person (or his or her heirs or legal personal representatives) who:

against any liability incurred by him or her as a director, alternate director, officer, employee or agent or person who holds or held such equivalent position.

We have entered into indemnity agreements with each of our current directors (the “Indemnity Agreements”) and employment agreements containing indemnification provisions with three of our executive officers, Jonathan Cherry, President and Chief Executive Officer, Mark Murchison, Chief Financial Officer, and Gregory A. Fontaine, Senior Vice President and General Counsel (the “Employment Agreements”), to provide these directors and executive officers additional contractual assurances regarding the scope of the indemnification set forth in our Articles and to provide additional procedural protections, subject to certain exceptions described below. The Indemnity Agreements, among other things, require us to indemnify each director to the fullest extent permitted by law, including but not limited to the indemnity under the Act, our Notice of Articles and Articles and the indemnity agreement, from and against any and all losses (including all costs, disbursements, charges, awards, expenses, losses, damages (including punitive and exemplary), fees (including any legal, professional or advisory fees or disbursements), liabilities, amounts paid to settle or dispose of any claim or satisfy any judgment, fines, penalties or liabilities) which the director may reasonably suffer, sustain, incur or be required to pay in respect of any claim arising out of the person’s services as a director. Similarly, the Employment Agreements require us to indemnify each of the aforementioned executive officers to the fullest extent permitted by law, including but not limited to the indemnity under the Act, our Notice of Articles and Articles, and the Articles of Incorporation and Bylaws of Perpetua Resources Idaho Inc., our wholly owned subsidiary, with respect to all liabilities and reasonable expenses which the officer may incur in any threatened, pending or completed action, suit or proceeding arising out of such officer’s services as an officer. The indemnity provided under the Indemnity Agreements and Employment Agreements will only be available if the applicable director or executive officer (the “Indemnified Party”) was acting honestly and in good faith with a view to the best interests of the Company in relation to the subject matter of the claim; and, in the case of a proceeding that is not a civil action/proceeding, the Indemnified Party had reasonable grounds for believing that the Indemnified Party’s conduct in respect of which the action/proceeding was brought was lawful.

Pursuant to the Indemnity Agreements, the Company has also agreed to maintain the coverage provided by directors’ and officers’ insurance policy listed therein and, in the event that such policy is discontinued for any reason, or in the event of a merger, amalgamation, take-over bid, arrangement, recapitalization, consolidation, liquidation, wind-up, dissolution, share exchange, material sale of assets or similar transaction in respect of the Company, the Company will cause to be purchased, maintained and administered for a period of six years after such discontinuance, insurance for the benefit of the Indemnified Party (the “Run-Off Coverage”), on similar terms to the extent permitted by law and provided such Run-Off Coverage is available on commercially acceptable terms and premiums (as determined by the board of directors in its reasonable and good faith opinion), provided that the premiums for the Run-Off Coverage will be deemed to be commercially acceptable if the total premiums for such Run-Off Coverage do not exceed 300% of annual premiums under the Policy at the time they are discontinued). The Employment Agreements also require the Company to maintain directors’ and officers’ insurance policy coverage. Pursuant to the terms of the Employment Agreements, each of the aforementioned executive officers is entitled to coverage under such policy on the same terms and conditions (including, without limitation, with respect to scope, exclusions, amounts and deductibles) as are available to other senior executives, during such executive’s employment and for a period of six years after the termination of employment. We are also required to maintain a customary, industry-standard Employed Lawyers Professional Liability insurance policy for Mr. Fontaine during Mr. Fontaine’s employment and for six years thereafter.

Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers or persons controlling the registrant pursuant to the foregoing provisions, the registrant has been informed that in the opinion of the SEC such indemnification is against public policy as expressed in the Securities Act, and is therefore unenforceable.
