Thesis Gold Commences Environmental Assessment Process for the Lawyers-Ranch Project

Thesis Gold Inc. ("Thesis" or the "Company") (TSXV: TAU,OTC:THSGF) (WKN: A3EP87) (OTCQX: THSGF) is pleased to announce that it has initiated the Environmental Assessment ("EA") and permitting process for the 100%-owned Lawyers-Ranch Gold-Silver Project ("Lawyers-Ranch" or the "Project") at both the provincial and federal levels. Concurrent submission of an Initial Project Description ("IPD") and Engagement Plan ("EP") to the British Columbia Environmental Assessment Office ("EAO"), and the IPD and a Plain Language Summary ("PLS") to the Impact Assessment Agency of Canada ("IAAC") marks the beginning of the permitting process, and an important milestone for Thesis and the Lawyers-Ranch Project.

The IPD outlines the Company's plans to develop and operate the Lawyers-Ranch Project. Located approximately 450 kilometres (km) north-northwest of the City of Prince George, and 275 km north of the Town of Smithers, the Project partially overlaps with the traditional territories of the Kwadacha Nation, Tsay Keh Dene Nation, Takla Nation, and Tahltan Nation (the "Nations").

Thesis is committed to meaningful Indigenous engagement and public participation throughout the EA and permitting processes. Since acquiring the Project in 2018, the Company has built strong, collaborative relationships with the Nations through agreements, co-design initiatives, and most recently, through direct equity ownership. Following the successful completion of the recent financing, Kwadacha Nation, Tsay Keh Dene Nation, and Takla Nation have become shareholders in Thesis, aligning their interests with the Project's long-term success.

Dr. Ewan Webster, President & CEO commented, "The submission of the IPD marks a key milestone in advancing the Lawyers-Ranch Project through the permitting process and reflects our shared commitment to developing a project that delivers lasting benefits for all stakeholders. We look forward to continued collaboration with Indigenous partners, local communities, and government regulators as we advance the Project in accordance with the highest environmental and social standards. With both the provincial and federal governments placing a strong emphasis on improving permitting efficiency and recognizing the critical role of responsible resource development in B.C.'s economy, this is an ideal time for Thesis to be commencing this next phase of the process."

On behalf of the Board of Directors,
Thesis Gold Inc.,
