Thesis Gold Inc. Announces Strategic 9.9% Investment by Centerra Gold Inc.

/NOT FOR DISTRIBUTION TO U.S. NEWSWIRE SERVICES OR DISSEMINATION IN THE UNITED STATES/

VANCOUVER, April 22, 2025 - Thesis Gold Inc. (TSXV: TAU) (WKN: A3EP87) (OTCQX: THSGF) ("Thesis" or the "Company") is pleased to announce the Company and Centerra Gold Inc. ("Centerra") have entered into a subscription agreement (the "Subscription") whereby Centerra will acquire 9.9% of the issued and outstanding common shares of the Company ("Common Shares").

Dr. Ewan Webster, President and CEO, shared, "We are excited to welcome Centerra as a strategic investor in Thesis. Centerra's interest is a strong endorsement of the extraordinary potential of the Lawyers-Ranch Project and the work our team has accomplished to date. Their deep technical expertise, operational experience, and regional presence through the Kemess asset present a clear opportunity for collaboration and unlocking district-scale synergies. We look forward to working alongside Centerra as we continue to advance and de-risk this emerging gold camp."

President and CEO of Centerra, Paul Tomory, commented, "We are pleased to support Thesis with this strategic investment. Thesis' recent Preliminary Economic Assessment, resource update, and drill results are very encouraging and demonstrate the potential of this highly prospective district. Given the proximity of our Kemess asset to the Lawyers-Ranch Project, we see the potential for substantial synergies, including the ability to leverage existing infrastructure to unlock regional potential. We look forward to seeing the results of their work and the potential the project holds for future resource growth."

Pursuant to the Subscription, Centerra has agreed to purchase, by way of private placement, 23,460,160 Common Shares at a price of $1.03 per Common Share for gross proceeds of $24,163,965. The issue price represents a 10% premium to the 5-day volume weighted average price of the Common Shares as traded on the TSX Venture Exchange (the "TSXV") immediately prior to executing the subscription agreement. The proceeds from the Subscription will be used for working capital and general corporate purposes, including work related to the technical studies currently underway at the Lawyers-Ranch Project. The Company anticipates the Subscription will close on or around April 28, 2025. Closing of the Subscription is subject to certain conditions including, but not limited to, receipt of approval of the TSXV.

In connection with the Subscription, Thesis and Centerra intend to enter into an investor rights agreement, whereby, subject to certain conditions, including time and ownership thresholds, the Company will grant Centerra certain financing and other participation rights to enable Centerra to maintain its shareholding interest in the Company, a board nomination right in the event that Centerra acquires 19.9% of the Company's issued and outstanding Common Shares and technical committee appointment rights among other customary investor rights included in the investor rights agreement.

Following the completion of a Preliminary Economic Assessment in 2024, Thesis is focused on advancing the project in 2025 through a Pre-Feasibility Study, completing key baseline work to initiate the Environmental Assessment process, and executing a significant summer exploration program. While advancing Lawyers-Ranch remains the focus, the proximity to Centerra's Kemess asset (Figure 1) presents longer-term opportunities for collaboration that could enhance efficiencies and support future development across the Toodoggone district.

All Common Shares issued pursuant to the Subscription will be subject to a statutory hold period of four months and one day from the date of closing, in accordance with applicable Canadian securities legislation.
