Thesis Gold Files Updated PEA for Lawyers-Ranch Project

Vancouver, British Columbia -- (October 1 6, 2024) – Thesis Gold Inc. ("Thesis" or the " Company")

(TSXV: TAU | WKN: A3EP87 | OTCQX: THSGF) is pleased to announce the Company has filed on

SEDAR+ an updated Preliminary Economic Assessment ( “PEA”) technical report (the “Report”) for its

wholly owned Lawyers-Ranch Project located in British Columbia, Canada. This updated PEA supersedes

the previously filed Lawyers-only PEA (effective date September 9, 2022).

The Report, entitled “Updated Preliminary Economic Assessment for the Lawyers -Ranch Project and

Property” was independently prepared by JDS Energy & Mining Inc. of Vancouver, British Columbia,

Canada in accordance with National Instrument 43-101 – Standards of Disclosure for Mineral Projects (“NI

43-101”) and has an effective date of August 30, 2024.

The updated PEA results support a 12,600 tonnes per day open pit mining operation over a 14-year

mine life. Highlights include:

• Strong Economics: Pre-tax internal rate of return (“IRR”) of 46.0%, pre-tax net present value at

a 5% discount rate (“NPV5%”) of C$1.99 billion, after-tax IRR stands at 35.2%, and an after-tax

NPV5% of C$1.28 billion, using US$1,930 per ounce of gold and US$24 per ounce of silver (see

Table 1).

• Gold Price Sensitivity: The project remains robust at a wide range of gold prices from US$1,750

to US$2,500 with after-tax IRR of 28.8% to 52.8% (see Table 2).

• Increased Production: The 2024 PEA saw a considerable increase in production versus the

previous (2022) PEA with a 32% increase in annual average production to 215,000 gold-equivalent

(“AuEq”*) ounces, including an average 273,000 gold-equivalent ounces annually over the first

three years, and a 55% increase in Life-of-mine (“LOM”) production to 3.0 million gold-equivalent

ounces, extending mine life to over 14 years.

• Low AISC: LOM all-in sustaining cash cost (“AISC”) of US$1,013 per ounce of gold equivalent.

• Quick Payback: The project offers a quick after -tax payback of 2.0 years, a 29% decrease

compared to the previous (2022) PEA.

• Capex: Initial capital expenditure is estimated at C$598.4 million, with a compelling after -tax

NPV5% to initial capital ratio of 2.1:1.

• Project Upside: Significant Mineral Resource growth potential remains across both Lawyers and

Ranch projects. The underground Mineral Resource at Lawyers is still open for expansion at depth,

while Ranch Mineral Resource zones also remain open. Additionally, there are over 20 unexplored

targets that hold potential for further discoveries.

The PEA and summary above, is preliminary in nature and includes the use of inferred mineral resources

that are considered too speculative geologically to have economic considerations applied to them that would

enable then to be categorized as mineral rese rves, and there is no certainty that the preliminary economic

assessment will be realized.

More details can be found on Thesis’ news release announcing the updated PEA dated September 5, 2024.

The PEA is available on SEDAR+ and Thesis’ website, www.thesisgold.com.
