*Private Placement of Common Shares to Hatch Ltd.*

On December 15, 2025, the Company entered into a subscription agreement with Hatch Ltd. ("<u>Hatch</u>") (the "<u>Hatch Subscription Agreement</u>") pursuant to which the Company agreed to sell and issue, for aggregate gross proceeds of approximately $4 million, 138,696 common shares, no par value, of the Company ("<u>Common Shares</u>" and such Common Shares to be issued and sold, the "<u>Hatch Private Placement Shares</u>") at a price of $28.84 per Common Share (the "<u>Hatch Private Placement</u>"), which was the closing price of the Common Shares on Nasdaq on Friday, December 12, 2025. The Hatch Private Placement Shares will be issued in two tranches. The first tranche will be comprised of 69,348 Common Shares and issued on the date that the Company enters into an agreement with Hatch for engineering, procurement and construction management ("<u>EPCM</u>") services relating to the Stibnite Gold Project. The second tranche will be comprised of 69,348 Common Shares and issued as soon as practicable after the later of (x) the date the board of directors of the Company makes a final investment decision with respect to the Stibnite Gold Project; and (ii) the date the Company signs definitive documentation with respect to project financing. The Hatch Subscription Agreement contains customary representations and warranties on the part of each of the parties. The Company will not pay any underwriting discounts or commissions with respect to the sale of the Hatch Private Placement Shares.

*Private Placement of Common Shares to Non-Affiliated Investor*

On December 12, 2025, the Company entered into a subscription agreement with a private, non-affiliated investor (the "<u>Investor Subscription Agreement</u>") pursuant to which the Company agreed to sell and issue, for gross proceeds of $28.84 million (i) 1,000,000 Common Shares (such Common Shares to be issued and sold, the "<u>Investor Private Placement Shares</u>"), and (ii) Common Share purchase warrants (the "<u>Warrants</u>"), which are exercisable to purchase up to an aggregate of 370,000 Common Shares (the "<u>Investor Private Placement</u>"). The Warrants will be issued in three equal tranches, with the first tranche expiring on December 23, 2026, and the second and third tranches expiring on the second and third year anniversaries, respectively, of issuance. The one-, two- and three-year Warrants will be exercisable at prices of $38.93, $43.26 and $47.59 per Common Share, respectively. The Warrants are subject to repurchase by the Company if the closing price of the Common Shares exceeds 130% of the respective exercise price of each tranche of Warrants for a specified period and a registration statement covering the Warrant Shares is effective. The warrant certificates contain customary adjustment provisions in connection with, among other things, (i) share splits and distributions, (ii) rights offerings and (iii) certain events involving a capital reorganization, reclassification, combination or merger of the Company. Pursuant to the terms of this Investor Subscription Agreement, the investor will also receive resale registration rights under the registration rights agreement entered into on October 28, 2025, by and among the Company and the investors party thereto (the "<u>Registration Rights Agreement</u>"). The Investor Subscription Agreement contains customary representations and warranties on the part of each of the parties. The Company will not pay any underwriting discounts or commissions with respect to the sale of the Investor Private Placement Shares. This transaction is expected to close on or about December 18, 2025.

The foregoing description of the terms of the Warrants and the Registration Rights Agreement do not purport to be complete and is qualified in its entirety by reference to the full text of the form of Warrant and the Registration Rights Agreement, which were filed as Exhibits 4.1 and 4.2 to the Company's Current Report on Form 8-K filed on October 28, 2025 and are incorporated by reference herein .

*Grant of Common Shares to Stibnite Foundation*

On December 12, 2025, the board of directors of the Company approved the issuance to the Stibnite Foundation of 150,000 Common Shares (the "<u>Foundation Shares</u>"). The issuance will be made pursuant to a community agreement dated November 30, 2018 (the "<u>Community Agreement</u>") with the Company's wholly-owned subsidiary, Perpetua Resources Idaho, Inc. (then, Midas Gold Idaho, Inc.) and certain of the communities closest to the Company's Stibnite Gold Project site located in Valley County, Idaho, pursuant to which, among other things, the parties agreed to establish the Stibnite Foundation. Pursuant to the Community Agreement, among other things, within 15 days of the Company receiving all permits and approvals necessary for the commencement of construction of the Stibnite Gold Project, the Company shall (i) make a grant of $100,000 to the Stibnite Foundation; and (ii) issue 150,000 Common Shares to the Stibnite Foundation. The Company will not pay any underwriting discounts or commissions with respect to the issuance of the Foundation Shares. The Company expects to issue the Foundation Shares on or about December 17, 2025.

The offer and sale, or grant (as applicable) of the Hatch Private Placement Shares, Foundation Shares, Investor Private Placement Shares, Warrants and the Warrant Shares to be issued upon exercise of the Warrants, was not registered under the Securities Act in reliance on the exemption from registration provided by Section 4(a)(2) of the Securities Act. The issuances of the Hatch Private Placement Shares, Foundation Shares, Investor Private Placement Shares and Warrants have not been registered under the Securities Act and such securities may not be offered or sold in the United States absent registration or an exemption from registration under the Securities Act and any applicable state securities laws.

*Selection of Engineering, Procurement, and Construction Management Manager*

On December 15, 2025, the Company announced that it had selected Hatch as the EPCM contractor for the Stibnite Gold Project. Under the EPCM model, Hatch will be responsible for:

&nbsp;&nbsp;&nbsp;&nbsp;· Comprehensive process plant and site infrastructure
engineering and design

&nbsp;&nbsp;&nbsp;&nbsp;· Procurement management for all major site equipment
and systems

&nbsp;&nbsp;&nbsp;&nbsp;· Construction management across the full process
facility scope and other site infrastructure

&nbsp;&nbsp;&nbsp;&nbsp;· Integrated project controls, reporting, and performance
management standards

The Company conducted an in-depth selection process which was guided by a multi-disciplinary evaluation matrix. Only firms with demonstrated technical depth, commercial competitiveness, and previous engagement with the Stibnite Gold Project were invited to bid. Hatch emerged as the clear leader across commercial, technical, and execution-readiness criteria. The Company and Hatch are currently negotiating terms of the definitive EPCM contract to reflect the terms of Hatch's winning bid. The EPCM contract is expected to be finalized in the coming weeks.

Hatch intends to invest $4 million in the Company, as described under Item 3.02 of this Current Report. The equity investment by Hatch was not a factor in the Company's selection of Hatch as EPCM contractor, and the terms of the EPCM agreement are not contingent on the Private Placement.

*Partnership with Idaho National Laboratory*

On December 9, 2025, the Company announced that it had entered into an agreement with the Idaho National Laboratory ("<u>INL</u>") via Battelle Energy Alliance LLC for the INL to host, commission, and operate a flexible, modular pilot processing plant expected to be capable of recovering various critical and defense-related minerals, including antimony from the Company's ores. This initiative is intended to demonstrate the feasibility of producing high-quality, military specification antimony trisulfide using material from the Company's Stibnite Gold Project. This pilot plant initiative is part of a broader partnership between the Company and the U.S. Army via the Defense Ordnance Technology Consortium ("<u>DOTC</u>") to secure domestic sources of critical minerals.

*Update on Antimony Off-Site Processing Request for Proposal Process*

As announced in September 2025, the Company is currently conducting a competitive process to identify and select a third-party processing facility to process commercial grade antimony from the Project when in production. The Company has received multiple proposals and is evaluating the proposed facilities for technical and economic feasibility. This review is ongoing in connection with the Company's ongoing project financing negotiations and a decision is now expected to be made in 2026.
