Description of the Updated PEA

The Updated PEA outlines a development approach for Goldfields’ current mineral resource through conventional open-pit mining and onsite gold recovery at a 4,950 tpd processing facility.

This assessment positions Goldfields for expedited advancement toward mine development. While different production scenarios were considered, all of which demonstrate robust economics, the Updated PEA focuses on a mine plan tailored to accelerate the path to production—maintaining throughput below 5,000 tpd to proceed without requiring a federal impact assessment. This expedited pathway is underpinned by established infrastructure, a de-risked resource base with 97% of ounces in the Indicated category, and the benefit of a Provincially-approved Environmental Impact Statement (“EIS”) from 2008 for a 5,000 tpd open-pit operation.

The Updated PEA was prepared by Ausenco Engineering Canada ULC (“Ausenco”) in accordance with National Instrument 43-101 – Standards of Disclosure for Mineral Projects (“NI 43-101”). The Updated PEA NI-43-101 Technical Report will be filed on SEDAR (www.sedar.com) within 45 days of the Updated PEA News Release dated September 23, 2025. 

Project Overview

The 100% owned Goldfields Project (“Goldfields” or the “Project”) is located approximately 13 kilometres south of Uranium City, Saskatchewan. Goldfields hosts the Box and Athona gold deposits, as well as additional gold showings within the prospective Goldfields Syncline. The Box deposit was historically mined underground between 1939 and 1942, producing 64,000 ounces of gold.

The Project is located within a historical mining area and benefits from established infrastructure, including a road and hydro-powerline to the Box deposit. Nearby facilities and services in Uranium City include bulk fuel, civils contractors, and a commercial airport.

Base Case Economic Results

The Updated PEA is preliminary in nature, given that it includes inferred mineral resources that are considered too speculative geologically to have the economic considerations applied to them that would enable them to be categorized as mineral reserves, and there is no certainty that the preliminary economic assessment will be realized.
The Updated PEA for Goldfields is based upon a subset of mineral resources comprising 97% indicated mineral resources and 3% inferred mineral resources.

Capital and Operating Costs

• Initial CAPEX: C$301 million, including contingency of C$51 million.
• Sustaining Capital: C$142 million over LOM.
• Operating Costs: C$41.0/t milled, including mining (38%), processing (37%), and G&A (25%).
• Closure Costs: C$15 million at end of mine life.

Mineral Resources

An updated Mineral Resource Estimate (“MRE”), effective date September 11, 2025, was completed as part of the Updated PEA to reflect a slightly lower cut-off grade due to increases in the gold price. Mineral resources are constrained within a conceptual open-pit shell. The updated MRE was prepared by SRK Consulting (Canada) Inc. (“SRK”) in accordance with CIM Guidelines and NI 43-101. This updated MRE replaces the previous MRE with an effective date of September 1, 2022, also completed by SRK, who used the same resource estimation procedures. SRK is also responsible for the development of the supporting mineralization models which were based upon structural and petrographic studies conducted by SRK.

The MRE reconciles to within 1% of historical mine production at Box when the historically reported process plant recovery of 96% is applied, providing additional confidence in the estimate.

Infrastructure

The Project benefits from historical investment and proximity to existing infrastructure:

• Road access to Uranium City (25 km), with municipal infrastructure, commercial airport (year-round commercial flights) and civils contractors.
• Power to be supplied via refurbishment of existing (currently inactive) 115 kV line from hydro-power stations, with peak demand of 12 MW. Line assessment currently underway by SaskPower.
• Freshwater supply from nearby Lake Athabasca.
• Tailings storage facility (“TSF”) designed for 21.9 Mt capacity, to be constructed in two phases.
• Waste rock storage facilities (“WRSF”) and low-grade stockpiles integrated into mine plan.

Site Layout 

Environmental, Social, and Permitting

• EIS approval granted in 2008 for an open-pit mine at Box and a 5,000 tpd processing facility remains valid.
• Additional approvals required for Updated PEA mine plan to address the time-lapse since original assessment work and changes in project footprint, including the addition of open-pit mining at the Athona deposit and the management of relatively larger volumes of waste rock and tailings.
• Environmental baseline studies have been initiated, to build upon and validate 10+ years of environmental data, with terrestrial and aquatic studies ongoing. The studies have been designed to establish a foundation for Provincial regulatory engagement and advancement in 2026.
• Well-developed community relationships, including Exploration Agreement (Nov 2022) providing consent up to and including bankable feasibility study.
• Engagement on project development has been initiated with Indigenous Nations and local Municipalities, with initial meetings to commence Q4 2025.
• At this time, no material environmental or social risks have been identified that cannot be reasonably mitigated.

Key Opportunities 

Accelerated Production Alternative: Onsite Concentrate Production

• Fast-Tracked Development: Unique to Goldfields, the Project benefits from its past-producing status and a valid 2008 EIS, enabling investigation of a fast-tracked, lower-capex route to production.
• High-Grade Concentrates: Prior SGS Canada - Lakefield testwork (2019) demonstrated exceptional potential—gravity coarse gold concentrates >1,000 g/t and subsequent sulphide flotation concentrates >200 g/t. New metallurgical studies (SGS - Sept, 2025) are underway to optimize recovery and assess marketability of high-grade gold concentrates.
• Capital & Timeline Benefits: A staged approach—initial gravity + sulphide concentrate production—could substantially reduce upfront capital requirements, shorten the development timeline, and advance Goldfields into production under the existing EIS framework.

Mineral Resource Growth: Exploration Drilling

• Resource Growth: Potential to expand the current mineral resources through exploration drilling, unlocking additional upside at Goldfields.
• Exploration Targets: Box (down-dip extensions; underground development potential), Athona (near-surface west), Frontier Lake (high-grade near-surface continuity), Golden Pond & Triangle (surface extensions).

Exploration Targets & Resource Growth Opportunities

Next Steps

1. Pre-Feasibility Study
   As recommended by Ausenco, the Updated PEA supports advancing Goldfields through Pre-Feasibility Study (“PFS”). Proposed programs include metallurgical testing and process optimization; geotechnical and hydrogeological studies; mine, infrastructure, and tailings engineering; environmental baseline updates and permitting; resource expansion and exploration drilling. Work has commenced on a post-PEA waste rock characterization study and additional planning is underway to commence key further de-risking studies toward PFS.
2. Accelerated Production Alternative: Onsite Concentrate Production
   Evaluation of the technical and commercial pathway for this staged development is ongoing utilising the existing permit framework and the encouraging gravity and concentrate testwork obtained to date. Following completion of the SGS testwork currently in progress, the evaluation is expected to be expanded to cover blended samples as well as variability testing across the two deposits.
3. Mineral Resource Growth: Exploration Drilling
   A 2,000–3,000 metre (15–20 holes) drilling program is planned to test growth potential beyond the Updated PEA mine plan.
4. Permitting
   • Advance environmental and permitting work to align the Updated PEA mine plan with regulatory requirements. This includes completing ongoing baseline studies to support regulatory engagement in 2026.
   • Continuing proactive community engagement under the current Exploration Agreement, with initial project development meetings beginning in Q4 2025.
