It is not defined under IFRS and may not be comparable to similar measures presented by other companies. Management believes that this measure provides useful supplemental information to investors in evaluating the Project's operating performance and its ability to generate cash flows. EBITDA is closely approximated in this model by Operating Cashflow, defined as Net Revenues less cash operating costs.

Nolan Peterson, CEO and Director of Atlas Salt, stated : "The Updated Feasibility Study marks another significant milestone in Atlas Salt's journey, highlighting Great Atlantic's potential as the leading undeveloped salt project in North America. This study reinforces our vision to deliver a long-life, low-cost operation at scale. It is supported by technical and logistical enhancements from the 2023 Feasibility Study that further reduce risks and position us for future success.

The improvement in projected free cash flow is especially significant as it validates the strengthened economics of Great Atlantic and enhances lender confidence in financing this world-class development. With the previously announced regulatory approval of our Early Works Development Plan, Atlas Salt is strategically positioned to advance Great Atlantic and create substantial value for all stakeholders.

We extend our gratitude to our employees, partners, the town of St. George's and the broader Western Newfoundland community, and our dedicated shareholders for their ongoing support and commitment as we complete the UFS and move forward with our plans. Their belief in Atlas Salt drives our progress. With the foundation we have built, and the momentum of this updated feasibility study, we look forward with confidence to realizing Great Atlantic's potential to help shape the future of salt supply in North America."

Summary of Updated Feasibility Study

The UFS was prepared by SLR Consulting (Canada) Ltd. ("SLR"), with contributions from specialized engineering and technical partners including Shaft and Tunnel Consulting Services Ltd., Terrane Geoscience Inc., Sandvik Mining and Rock Solutions ("Sandvik"), and Tamarack Resources.

The Updated Feasibility Study builds on the 2023 Feasibility Study ("2023 FS"), incorporating optimizations in mine design, throughput, port logistics, and capital efficiency. The results confirm Great Atlantic as a large scale, high-purity, low-cost underground salt project strategically positioned to serve the North American market.

General Description of Operations and Process Plan

The capital and operating cost estimates in the Updated Feasibility Study have been prepared in accordance with the guidelines of the Association for the Advancement of Cost Engineering (AACE) for a Class 3 estimate. This level of estimate is typically based on feasibility-level engineering, vendor quotations, and discipline-level design sufficient to support a financing decision. The accuracy range for initial capital costs is considered to be within approximately -10% to +30%, while the accuracy for operating costs is estimated to be within approximately -10% to +20%. Costs are based on Q3 2025 data.

The estimates incorporate contingency allowances to reflect the current design, anticipated execution risks, and prevailing market conditions for labour, materials, and equipment. They are also benchmarked against comparable projects and historical data for underground salt operations.

The changes are principally related to different pillar and room dimensions, and minor variances in level spacing.

Mining Method and Design

  • Method : Room-and-pillar underground mining using continuous miners.

  • PillarConfiguration : Designed for long-term stability, with pillar dimensions and sequencing optimized for maximum extraction while ensuring ground control.

  • Development : Access via surface portal and conveyor decline system; mine layout configured for scalable expansion.

  • ProductionRate : 4.0 Mtpa steady-state by Year 4, with ramp-up commencing in Year 1.

  • Daily Production Rate: Approximately 11,500 tonnes per day at steady-state capacity.

Processing and Product Handling

Salt is crushed and screened underground to market specifications, conveyed to surface, and transported to the port via covered conveyor. No chemical processing or water usage in processing is required, other than the application of an anti-caking agent immediately prior to shipment offsite.

Infrastructure and Logistics

  • Port : Dedicated port storage and shiploading system designed for 4.0 Mtpa throughput at full operations.

  • Shiploading : Continuous conveyor-fed shiploader with optimized cycle times to minimize vessel demurrage.

  • Storage : Surface stockpile capacity of approximately 72 kt, equivalent to 6.5 days of average production.

  • Utilities : Connection to provincial power grid with dedicated substation;

  • Power: The Project is expected to require approximately 10 megawatts (MW) of connected load at steady-state operations, sourced from the provincial grid via a dedicated substation.

  • Accommodation: No camp facilities are included in the design, with the Project benefiting from proximity to established communities and existing regional infrastructure.

Operating Costs

The operating cost estimates were developed from first principles using a combination of vendor quotations, budgetary pricing from equipment suppliers, labour and power cost assumptions specific to Newfoundland, and benchmarking against comparable underground salt operations. Mining, processing, and port handling costs reflect the planned use of continuous miners, conveyor haulage, and high-capacity shiploading infrastructure. General and administrative (G&A) costs are based on staffing requirements and site services, while closure and bonding provisions reflect anticipated regulatory obligations. Costs are expressed on a LOM average basis and are considered accurate to within -10% to +20%, consistent with a feasibility-level estimate.

North America consumes over 25 million tonnes of road salt annually, a significant portion of which is imported, with Eastern Canada and the U.S. Northeast representing the highest concentration of demand. Regional supply challenges, combined with increasing winter severity and aging supply bases, create a strategic opportunity for Great Atlantic to deliver reliable, high-purity supply into these critical markets.

Permitting and Regulatory Approvals

The Great Atlantic Salt Project is advancing within a well-defined permitting framework under the Government of Newfoundland and Labrador.

  • Environmental Assessment (EA): Conditionally released from the provincial EA process in 2024, establishing government approval to advance the Project.

  • Early Works Development Plan: Approved in 2025, enabling shovel-ready commencement of site preparation, civil works, and other enabling infrastructure.

  • Capital Development Plan: To be submitted following completion of detailed engineering, covering underground mine development, processing, and port facilities.

  • Commercial Production Approval: The final stage permit, aligned with commissioning of mine and port facilities.

The permitting pathway for Great Atlantic is clear, with major approvals in place and a structured process established for capital development and eventual production.

Next Steps

Atlas Salt will advance the Project through:

  • NI 43-101 Technical Report Filing: Submission of the Updated Feasibility Study Technical Report within 45 days.

  • Financing Discussions: Continued engagement with project lenders, strategic offtake partners, and equity participants to advance funding solutions.
