NOTICE‐AND‐ACCESS NOTIFICATION TO SHAREHOLDERS FOR THE

ANNUAL GENERAL OF SHAREHOLDERS ON MAY 18, 2023 (the "Meeting")

You are receiving this notification as Perpetua Resources Corp. (the "Company") is using "notice-and-access", as defined under National Instrument 54-101Communication with Beneficial Owners of Securities of a Reporting Issuer, for electronic delivery of the Company's Proxy Statement dated April 6, 2023 (the "Proxy Statement") to its shareholders in relation to the Meeting. Under notice-and-access, Canadian companies are no longer required to deliver physical paper copies of certain materials relating to the annual meeting to their shareholders, unless requested by shareholders. Instead, electronic versions can be posted online for shareholder access and review. This new means of delivery is more environmentally friendly as it will help reduce paper use and will also reduce the cost of printing and mailing materials to shareholders.

STRATIFICATION USED: NO

The Company will not use procedures known as "stratification" with its use of notice-and-access in relation to the Meeting. Stratification occurs when a reporting issuer using the notice-and-access provisions provides a paper copy of the relevant information circular to some, but not all, shareholders with a notice package in relation to the relevant meeting. In relation to the Meeting, all shareholders will receive the required documentation under notice-and-access, which will not include a paper copy of the Information Circular.
