VANCOUVER, BC, Feb. 18, 2025 /CNW/ - Thesis Gold Inc. ("Thesis" or the "Company") (TSXV: TAU) (WKN: A3EP87) (OTCQX: THSGF) is pleased to announce the remaining drill results from its 2024 program at the Ranch area, part of its 100%-owned, road-accessible Lawyers-Ranch Project in British Columbia's Toodoggone mining district.

The 2024 drill program was strategically designed to advance engineering and environmental baseline studies (Figure 1), both essential to the Prefeasibility Study (PFS) led by Ausenco Engineering Canada ULC and Mining Plus Canada Consulting Ltd. The PFS remains on track for Q4 2025 completion, supporting the Environmental Assessment (EA) process set to commence later this year. The study will build on the positive results of the 2024 Preliminary Economic Assessment (PEA) (see Company news release September 5, 2024), which outlined robust project economics, including an after-tax NPV (5%) of C$1.28 billion, a 35.2% IRR, and a 2.0-year payback period. The PEA also highlighted a strong production profile, projecting over 215,000 AuEq oz/year for 14 years at an AISC of US$1,013.

In parallel, exploration and near-resource drilling continue to highlight the potential for further resource growth at Ranch through new discoveries (see Company news release from November 13, 2024), and the expansion and upgrading of ounces outlined in the PEA.

Key Highlights:

Advancing Towards Prefeasibility Study (PFS) and Environmental Assessment (EA) Processes:

• 2,266 metres (m) of drilling focused on geotechnical and hydrogeological studies.
• 17 geotechnical drill holes providing crucial data for mine design.
• 6 hydrogeology drill holes supporting environmental modelling for permitting.

Multipurpose Geotechnical Drilling:

• Near-surface broad mineralized zones and high-grade intervals, including;
  • 27.50 m of 2.08 g/t AuEq** in hole 24GTDD011.
  • 40.50 m of 1.20 g/t AuEq** in hole 24GTDD010.
  • 0.70 m of 48.86 g/t AuEq** in hole 24GTDD015.

Resource Growth:

• Drillhole 24TH2DD002 (Table 1, Figures 2 and 3) intersected:
  • 19.58 m of 1.15 grams per tonne gold (g/t Au) and 9.92 m of 2.69 g/t Au, extending mineralization ~40 m at depth ~30 m along strike at Thesis II.
  • High-grade interval of 26.29 g/t AuEq** over 0.67 m indicates higher grade domains.
  • Indicates potential to expand the 2024 mineral resource estimate.
• Geotechnical drillhole 24GTDD008 ended in mineralization, extending the strike length of a copper-gold mineralized domain at Bingo that remains open for testing.
  • 10.50 m of 0.76 g/t Au and 0.22% copper (Cu), including 5.00 m of 0.8 g/t Au and 0.37% Cu (Table 1).
  • Originally drilled for geotechnical purposes, this hole underscores additional expansion potential within the existing mineral resource estimate.

Next Steps

• 2025 Drilling Program: Focused on expanding near-resource mineralization and testing high-priority regional epithermal and porphyry targets.
• H2 2025: Commencement of the Environmental Assessment (EA).
• Q4 2025: Completion of the Prefeasibility Study (PFS).

Ewan Webster, President and CEO, shared, "The 2024 drill program played a critical role in positioning us to commence both the PFS and the EA process—key milestones that will drive project development and permitting decisions. Positive results from near-resource exploration have encouraging implications for the potential to expand and upgrade our confidence on the mineral resource defined in the 2024 PEA, which demonstrated strong project economics highlighted by an after-tax NPV (5%) of C$1.28 billion, an IRR of 35.2% and a payback period of 2.0 years. This shows that the Ranch area of the larger project still provides significant potential for resource growth and, in turn, improved project economics."

Engineering and Environmental Insights from the 2024 Program

The 2024 program provided critical geotechnical and hydrogeological data for mine design and permitting while also uncovering additional mineralization potential.

• Water monitoring drill holes provide baseline environmental data for the EA process.
• Geotechnical drilling was designed to assess rock quality, directly informing mine design and engineering decisions.
• Unexpected mineralized intercepts, like those in Drillhole 24GTDD008, will be incorporated into future exploration models.

These insights will support the PFS currently underway, guiding resource model refinement and 2025 drilling plans.

Geological Insights from the 2024 Program

Exploration drilling in the 2024 program focused on near-resource expansion at Bingo and Thesis II, as well as new targets defined at Ring and Golden Furlong (Figure 1). The Company's press release dated November 13, 2024 outlined a new discovery at the Ring zone and overprinting alteration relationships and a narrow zone of anomalous silver at Golden Furlong. Near-resource exploration at Bingo and Thesis II returned encouraging gold, silver, and copper intercepts. These results emphasize that while the 2024 PEA outlined a near-surface high-grade Mineral Resource, the potential exists to find more mineralization and expand the mineral resource at the Ranch area of the Lawyers-Ranch project.

Drillhole 24TH2DD002, intersected multiple mineralized zones at Thesis II, and successfully expanded mineralization at depth (Figure 3) and along strike. The shallowest of three mineralized intervals intersected 19.58 m of 1.15 g/t Au, including 8.58 m of 2.17 g/t Au from 131.00 to 150.58 m core length. This intercept, approximately 40 m vertically and 30 m laterally from previous drilling, reinforces confidence in the mineralized model and may contribute to a resource upgrade. Additionally, a ~10 m interval beginning at 177.08 m core length returned anomalous gold and silver, including 3.92 m of 5.53 g/t Au and 8.70 g/t Ag, refining the mineralized domain and filling a key data gap. The deepest intercept, 3.00 m of 1.04 g/t Au, aligns well with previously modelled mineralization. These mineralized zones occur within volcanic rocks altered to white mica + dickite ± silica, a characteristic alteration style of high-sulfidation epithermal systems, consistent with the broader Thesis II zone and other areas across Ranch.

Exploration Upside

The Toodoggone District shares key geological similarities with BC's Golden Triangle, particularly in its tectonic setting and magmatic-volcanic history. Both regions belong to the Stikine Terrane (Stikinia), one of British Columbia's most prolific mineral belts, known for its Triassic-Jurassic volcanic and plutonic rocks that host major deposits and mines. A significant regional prospectivity marker, the "red line unconformity," first recognized in the Golden Triangle, also extends into the Toodoggone. This boundary between Triassic and Jurassic rocks has been spatially linked with major porphyry and epithermal deposits. Notably, the Lawyers-Ranch epithermal system, the Kemess copper-gold porphyry, and the recently discovered porphyry mineralization at Joy (Amarc Resources and Freeport McMoRan JV) are all positioned along or near this stratigraphic marker (Figure 4). At Lawyers-Ranch, this unconformity is present at both the northern and southern extents of the tenure and is likely present beneath Jurassic Toodoggone rocks exposed at surface.

The genetic link between epithermal mineralization, hydrothermal alteration, and nearby porphyry systems is well established (Figure 5). The Lawyers deposit (~4 Moz MRE) represents a low-sulfidation epithermal gold-silver system, while the Ranch deposit (~700 koz MRE) is a high-sulfidation epithermal system characterized by argillic to advanced argillic to silicic alteration—hallmarks of a lithocap environment typically associated with an underlying porphyry. Lawyers is controlled by a broad fault structure with multiple hydrothermal veining events, and the Ranch system is a ~40 km² alteration footprint that hosts multiple structurally controlled mineralized zones. The variation in mineralization and alteration styles, along with evidence of overprinting, multiphase hydrothermal activity across the Lawyers-Ranch project area suggests the presence of a large, district-scale magmatic-hydrothermal system.

Recent discoveries, coupled with an evolving geological model, reinforce the potential for the Toodoggone District to emerge as a premiere fertile porphyry-epithermal camp. Thesis Gold remains committed to advancing this potential through continued exploration in 2025.
