The updated Mineral Resource Estimate is a key component in the upcoming update to the Preliminary Economic Assessment, slated for completion in Q3 2024. This MRE outlines both pit-constrained resources—defined by a conceptual pit shell with Mineral Resources at a lower cut-off grade of 0.4 g/t AuEq*—and out-of-pit Mineral Resources, with a lower cut-off grade of 1.5 g/t AuEq* and that demonstrate excellent continuity utilizing an industry standard conceptual stope optimizer software. While they are indicative of the potentially mineable Mineral Resources through conceptual open-pit and underground mining methods, this will be determined through a cross-over analysis in the upcoming updated PEA. The cross-over analysis will assess the most advantageous depths for transitioning from open-pit to underground mining methods to enhance economic efficiency, and overall conversion of Mineral Resources to potentially mineable Mineral Resources. At the Lawyers area drilling suggests that higher grade material is situated at the bottom of the conceptual pit-constrained Mineral Resource and extends below into the out-of-pit zone at both Cliffs Creek and Dukes Ridge, where underground mining could allow production earlier in the mine life. Moreover, the cut-off grade sensitivity analysis of the MRE at the Ranch project, shows a clear opportunity of near-surface, high-grade material by initiating production from higher-grade starter pits. These options will be evaluated in the updated PEA, with a strategy to integrate high-grade underground Mineral Resources and starter pits from Ranch early on to establish an optimized mining schedule to reduce the payback period. In addition, given the location and grade of the defined additional ounces and the revised mine plan contemplated in the upcoming PEA, there is an expectation that there will be a higher conversion of ounces in the MRE (M&I and Inferred) into potentially mineable ounces in the updated PEA relative to the previous PEA on only the Lawyers Project.

Notes:

1. Mineral Resources that are not Mineral Reserves do not have demonstrated economic viability.

2. The estimate of Mineral Resources may be materially affected by environmental, permitting, legal, title, taxation, socio-political, marketing, or other relevant issues.

3. The Inferred Mineral Resource in this estimate has a lower level of confidence than that applied to an Indicated Mineral Resource and must not be converted to a Mineral Reserve. It is reasonably expected that the majority of the Inferred Mineral Resource could potentially be upgraded to an Indicated Mineral Resource with continued exploration.

4. The Mineral Resources were estimated in accordance with the Canadian Institute of Mining, Metallurgy and Petroleum (CIM), CIM Standards on Mineral Resources and Reserves, Definitions (2014) and Best Practices Guidelines (2019) prepared by the CIM Standing Committee on Reserve Definitions and adopted by the CIM Council.

5. Historical mined areas were removed from the block-modelled Mineral Resources.

6. Economic assumptions used include US$1,850/oz Au, US$24/oz Ag, 0.76 US$:CDN$ FX, process recoveries of 90% and 92% Au for Lawyers and Ranch, respectively, 88% Ag for both projects, 85% Cu for Ranch, a C$15/t processing cost, and a G&A cost of C$5/t. The resulting gold equivalency ratio of Au:Ag ratio was 1:80 and Au:Cu was 1:7315.

7. The constraining pit optimization parameters were C$3.25/t mineralized and waste material mining cost and 52° pit slopes. Pit-constrained Mineral Resources are reported at an AuEq cut-off of 0.4 g/t.

8. The Out-of-Pit Mineral Resources include blocks below the constraining pit shell within underground mining shapes. A mining cost of C$85/t mineralized, in addition to the economic assumptions above, results in an underground (UG) AuEq cut-off of 1.5 g/t. Mining shapes are generated using stope optimization with an objective of maximizing the total metal above the cut-off with a minimum dimension of 1.5 m (W) by 15 m (H) by 15 m (L). All "take all" material within the mining shapes is reported, regardless of whether the estimated grades are above the optimized cut-off grade.

9. Details of the MRE will be provided in a Technical Report with an effective date of April 26, 2024, prepared in accordance with NI 43-101 standards, which will be filed under the Company's SEDAR+ profile within 45 days of this news release.

Quality Assurance and Control
Results from samples were analyzed at ALS Global Laboratories (Geochemistry Division) in Vancouver, Canada (an ISO/IEC 17025:2017 accredited facility). The sampling program was undertaken by Company personnel under the direction of Rob L'Heureux, P.Geol. A secure chain of custody is maintained in transporting and storing of all samples. Gold was assayed using a fire assay with atomic emission spectrometry and gravimetric finish when required (+10 g/t Au). Drill intervals with visible gold were assayed using metallic screening. Rock chip samples from outcrop/bedrock are selective by nature and may not be representative of the mineralization hosted on the Project.

The technical content of this news release has been reviewed and approved by Michael Dufresne, M.Sc, P.Geol., P.Geo., and Eugene Puritch, P.Eng., FEC, CET both Qualified Persons as defined by National Instrument 43-101.

About Thesis Gold Inc.

Thesis Gold is unlocking the combined potential of the Lawyers-Ranch Gold-Silver Project in the Toodoggone mining district of north central British Columbia, Canada. A 2022 Preliminary Economic Assessment for the Lawyers project alone projected an open-pit mining operation yielding an average of 163,000 gold equivalent ounces annually over a 12-year span¹. By integrating the Ranch Project, the Company aims to enhance the economics and bolster the overall project's potential. Central to this ambition was the expansive 2023 drill program, which continues to define a high-grade out-of-pit Mineral Resource at Lawyers and augment the near-surface high-grade deposits at Ranch. The project now boasts a combined Measured & Indicated Mineral Resource of 4.0 Moz and an Inferred Mineral Resource of 727 koz, at respective grades of 1.51 and 1.82 g/t AuEq. The Company roadmap includes, new metallurgical work, a robust 2024 exploration and drill program and a combined updated Preliminary Economic Assessment slated for Q3 2024. Through these strategic moves, Thesis Gold intends to elevate the Ranch-Lawyers Project to the forefront of global precious metals ventures.
