Overview

Perpetua Resources (formerly Midas Gold Corp.) was incorporated on February 22, 2011 under the Business Corporations Act (British Columbia) (the "BCBCA"). The Corporation was organized to hold shares in wholly owned subsidiaries that locate, acquire, develop and restore mineral properties located principally in the Stibnite - Yellow Pine mining district in Valley County, Idaho, USA. The Corporation's principal asset is 100% ownership in subsidiaries that control the Stibnite Gold Project. The Corporation currently operates in one segment, mineral exploration in the United States. The registered office of the Perpetua Resources is 400-725 Granville St, Vancouver, BC, V7Y 1G5, Canada and the corporate head office is located at 201-405 S 8th St, Boise, ID 83702, USA.

COVID-19 Response

The Company has implemented policies at its offices in Boise and Donnelly designed to ensure the safety and well-being of all employees and the people associated with them. In that regard, to reduce risk, our employees have been encouraged to get fully vaccinated against COVID-19, have been asked to work remotely, avoid non-essential business travel, when possible, adhere to good hygiene practices, and engage in social distancing. Continuation of COVID-19 in 2022 and beyond could impact employee health, workforce productivity, insurance premiums, ability to travel, the availability of industry experts, personnel and equipment, restrictions or delays to field work, studies, and assay results, and other factors that will depend on future developments that may be beyond our control.

Recent Key Developments

2022 Outlook and Goals

Perpetua Resources' vision is to provide the United States with a domestic source of the critical mineral antimony, develop one of the largest and highest-grade open pit gold mines in the country and restore an abandoned brownfield site. In 2022, Perpetua Resources continues to focus on advancing the permitting for the Stibnite Gold Project through the National Environmental Policy Act ("NEPA") process. The NEPA process is intended to ensure that federal agencies and the public are informed of a proposed action's potential environmental impacts before a final decision is made by the agency regarding the action.

In response to public comments received on the Draft Environmental Impact Statement ("DEIS"), Perpetua Resources submitted a refined proposed action to the USFS in December 2020. To ensure a full analysis of the improved Project, the USFS will issue a Supplemental Draft Environmental Impact Statement ("SDEIS") followed by an opportunity for public comment. The preliminary SDEIS was circulated for cooperating agency review in April 2022. The publication of the SDEIS for public review and comment is expected in early third quarter 2022. The USFS is expected to provide a formal schedule later this year regarding the remaining steps in the NEPA review process.

First Quarter 2022 Highlights

? Zero lost time incidents or reportable environmental spills

? Announced USFS expected to publish the SDEIS for public review and comment in

the third quarter of 2022

? Promoted Jessica Largent to CFO and further strengthened team with hiring of

Chris Fogg as Manager of Investor Relations

? Strengthened Board with appointment of Laura Dove who brings three decades of

external affairs and stakeholder management experience to Perpetua

? Launched a Sustainability Roadmap which outlines 13 goals to guide the Company

as it advances the Stibnite Gold Project towards development

NET LOSS                                                     $    6,244,894    $    4,716,577


Net Loss

Net loss for the three months ended March 31, 2022 was $6.2 million compared with a net loss of $4.7 million for the three months ended March 31, 2021. This $1.5 million increase compared to the prior year period was primarily attributable to a $11.6 million decrease in the gain related to the change in fair value of the convertible note derivative, a $0.5 million decrease in the gain related to the change in fair value of the warrant derivative and a $0.6 million increase in professional fees. These changes were partially offset by a $7.5 million decrease in environmental liability expense, a $2.0 million decrease in exploration expenses, and a $0.6 million decrease in corporate salaries and benefits. As noted above, for the three months ended March 31, 2022, the Company's main focus was the continued evaluation and advancement of the Stibnite Gold Project.

Consulting

This expense relates to consulting services provided to the Corporation that do not relate to the exploration and evaluation of the Stibnite Gold Project. Consulting fees for the three months ended March 31, 2022 are 90% lower than the previous year due to consulting work to support various corporate activities in the first quarter of 2021, including the share consolidation and listing on the NASDAQ.

Corporate Salaries and Benefits

This expense results from salaries and benefits of the employees that are not directly related to the exploration and evaluation of the Stibnite Gold Project, primarily corporate employees. Salaries and benefits for the three months ended March 31, 2022 were $0.6 million, or 66%, lower than the previous year primarily due to severance payments made to corporate employees in the first quarter of 2021 and lower stock-based compensation.

Directors' Fees

Each of the Corporation's non-executive directors is entitled to annual base fees paid in quarterly installments, with the independent Lead Director, Chairs of Board Committees and Members of Board Committees receiving additional fees commensurate with each role. Directors' fees are inclusive of cash fees and share-based compensation (deferred share units and stock options). This

Table of Contents

expense for the three months ended March 31, 2022, is $41,263, or 14%, lower than the previous year primarily due to the number of stock options vesting in the first quarter of 2021.

Exploration

This expense relates to all exploration and evaluation expenditures related to the Stibnite Gold Project, including labor, drilling, field operations costs, engineering, permitting, environmental, legal and sustainability costs. The Company's exploration expenses of $4.6 million during the three months ended March 31, 2022 are $2.0 million, or 31%, lower than the three months ended March 31, 2021 primarily due to a $1.4 million decrease in consulting and labor cost including lower stock based compensation expense, a $0.5 million decrease in permitting, and a $0.2 million decrease in engineering partially offset by a $0.3 million increase in legal and sustainability. Additional details of expenditures incurred are as follows:

Exploration                              $      4,560,053    $      6,580,863

Environmental Liability Expense

This expense relates to the ASAOC signed in January 2021 to voluntarily address environmental conditions at the abandoned mine site. Upon signing of the ASAOC, the Company recorded an immediate expense of $7,473,805 and a corresponding environmental reclamation liability. Cost estimates were developed with the use of engineering consultants, independent contractor quotes and the Company's internal development team, and the timing of cash flows is based on the current schedule for early action items. In the three months ended March 31, 2022, the total cost estimate to complete Phase 1 early cleanup actions did not change. As of March 31, 2022, the estimate for the environmental liability was $9.4 million.

Office and Administrative

This expense is predominantly insurance policies for the U.S. offices and is $258,785, or 55%, lower for the three months ended March 31, 2022, than the three months ended March 31, 2021 primarily due to lower insurance premiums.

Professional Fees

This expense relates to the legal and accounting costs of the Corporation. The costs for the three months ended March 31, 2022 were $567,193, or 339%, higher than the three months ended March 31, 2021 primarily due to legal fees to support the Company's transition to a U.S. Domestic Issuer and increased accounting fees related to the change in the basis of accounting for the Company's consolidated financial statements from international standards to U.S. GAAP.

Shareholder and Regulatory

This expense relates to marketing, licenses and fees, and shareholder communications. The expense for the three months ended March 31, 2022 is $92,562, or 37%, lower than the three months ended March 31, 2021 primarily due to fees related to the NASDAQ listing which commenced in February 2021.

Change in Fair Value of Warrant Derivative

The Corporation issued 200,000 warrants in a financing transaction in May 2013, with an exercise price denominated in Canadian dollars. The Company determined that warrants with an exercise price denominated in a currency that is different from the entity's functional currency should be classified as a derivative and carried at their fair value. Any changes in their fair value from period to period have been recorded as a gain or loss. There are no circumstances under which Perpetua Resources will be required to pay cash upon exercise or expiry of the warrants or finder's options (see Note 4 in the Condensed Consolidated Financial Statements - unaudited).

Change in Fair Value of Convertible Note Derivative

The Corporation issued unsecured convertible notes with an interest rate of 0.05% per annum in March 2016 and March 2020 (together, the "Convertible Notes") with an exercise price denominated in Canadian dollars. The Company determined that the Convertible Notes with an exercise price denominated in a currency that is different from the entity's functional currency should be classified as a derivative and carried at their fair value. Any changes in their fair value from inception to balance sheet date have been recorded as a gain or loss in the Consolidated Statements of Operations. The convertible note derivative is valued at fair value. The decrease in fair value is due to the conversion of Convertible Notes during the year. During 2021, the remaining Convertible Notes in the aggregate principal amount of C$15,409,901 were converted for 4,351,850 common shares of Perpetua Resources at a conversion rate of C$3.541 per common share (see Note 4 in the Condensed Consolidated Financial Statements - unaudited).

Finance Costs

Finance costs for the Corporation include accretion of note discount and interest expense related to the Convertible Notes described above. No such expense was recognized for the three months ended March 31, 2022 given the remainder of the Convertible Notes were converted in 2021.

Foreign Exchange Loss

Changes in foreign exchange are driven by the change in value of the Canadian Dollar compared to the U.S. Dollar and the impact the change has on translating the Corporation's Canadian dollar denominated balances. The impact was larger in the first quarter of 2021 compared to the first quarter of 2022 primarily due to the translation on the Convertible Notes and convertible note derivatives which were fully converted in 2021.

Interest Income

This income results from interest received on the Company's cash balances. Interest income increased $7,572 in the three months ended March 31, 2022, compared to the three months ended March 31, 2021 as a result of higher average cash balances in the first quarter of 2022.

Liquidity and Capital Resources

Capital resources of Perpetua Resources consist primarily of cash and liquid short-term investments. As of March 31, 2022, Perpetua Resources had cash and cash equivalents totaling approximately $41.2 million, approximately $1.0 million in other current assets and $2.0 million in trade and other payables.

In August 2021, the Corporation completed a public offering for total gross proceeds of $57.5 million to be used to continue permitting, early restoration and field operations, engineering and design and general corporate purposes.

With its current capital resources, Perpetua Resources believes that it has sufficient funds to continue to advance the regulatory process related to permitting for mine development beyond 2022. Perpetua Resources plans to:

Continue engaging with Project stakeholders to provide those stakeholders with

? the opportunity for a better understanding of the Project concepts and to

provide a forum for such stakeholders to provide further input into the

Project;

Continue to collect environmental baseline data in support of the ongoing

? regulatory processes related to permitting for site restoration and

redevelopment of the Project;

? Continue to advance the regulatory process for the restoration and

redevelopment of the Project; and

? Continue to advance the voluntary early cleanup actions under the ASAOC.

It is management's opinion, based on the Corporation's current capital resources and liquidity that the Corporation will have sufficient assets to discharge its liabilities as they become due, to continue to advance the Stibnite Gold Project for at least 12 months from the date these first quarter 2022 financial statements are issued, and to meet its administrative and overhead requirements for more than a year. Future financings to fund construction are anticipated through debt, equity, project specific debt, and/or other means. Our continued operations are dependent on our ability to obtain additional financing or to generate future cash flows. However, there can be no assurance that we will be successful in our efforts to raise additional capital on terms favorable to us, or at all.

Our anticipated expenditures in fiscal year 2022 are approximately $27.5 million, which are expected to be funded from cash on hand. These expenditures include an estimated $12.2 million to fund permitting of the Stibnite Gold Project, $10.5 million for general corporate purposes and administrative costs, $0.7 million for engineering and design work and $4.1 million to advance early restoration and continue field operations. These costs are subject to change due to cost over-runs, delays or other unbudgeted events.
