Thesis Gold Contracts Ausenco and Mining Plus to Commence Pre-Feasibility Study for Lawyers-Ranch Project

Vancouver, British Columbia--(Newsfile Corp. - January 9, 2025) - Thesis Gold Inc. (TSXV: TAU) (WKN: A3EP87) (OTCQX: THSGF) ("Thesis" or the "Company") is pleased to announce that it has engaged Ausenco Engineering Canada ULC ("Ausenco") and Mining Plus Canada Consulting Ltd. ("Mining Plus") to complete a Pre-Feasibility Study (PFS) prepared in accordance with NI 43-101 for its wholly owned Lawyers-Ranch Project in British Columbia. This PFS will build upon the strong project economics outlined in the Preliminary Economic Assessment (PEA) filed in September 2024, which demonstrated an after-tax NPV (5%) of C$1.28 billion, an IRR of 35.2%, and a payback period of just 2.0 years¹ (see Thesis news release of September 5, 2024).

Following a rigorous selection process, Thesis has chosen to partner with Ausenco and Mining Plus due to their position as industry leaders with extensive expertise in engineering, process design, and mine planning. Thesis is confident in the partnership's ability to produce a robust and complete PFS, which will offer a foundation for the project as it progresses through permitting, detailed engineering, and towards construction. Additionally, Knight-Piésold, F. Wright Consulting, and One-Eighty Consulting will continue their contributions from the PEA stage, focusing on tailings, water and waste rock management, metallurgy, and permitting, respectively.

"We are excited to collaborate with Ausenco and Mining Plus, two highly respected firms recognized for their excellence in engineering and mining studies," said Dr. Ewan Webster, President and CEO of Thesis Gold. "This milestone represents an important step forward as we continue to unlock the value of the project and advance towards our goal of building a sustainable and profitable mining operation."

The PFS is scheduled to be completed in Q4 2025 and will be filed on SEDAR+ when available. Work will progress in line with the ongoing Environmental Assessment process, with necessary finalized design items scheduled to be completed prior to submission of the Detailed Project Description in the second half of 2025.
