INDEPENDENT FEASIBILITY STUDY AND EXPANSION CASE FOR ATLAS SALT'S GREAT ATLANTIC PROJECT

Atlas Salt Inc. has released the results of a feasibility study (FS) and updated mineral resource estimate prepared by SLR Consulting (Canada) Ltd. on its 100-per-cent-owned Great Atlantic salt project located in western Newfoundland, Canada. The FS represents a significant economic improvement over the preliminary economic assessment (PEA), also completed by SLR, released by Atlas on Jan. 30, 2023 (all figures in Canadian dollars).

In addition, SLR has also provided an expansion case to four million tonnes per year (Mtpa) of road deicing salt over a 47.5-year mine life presented at a PEA-level (preliminary economic assessment) analysis. This demonstrates a robust upside production scenario with a pretax net present value (NPV) at 8 per cent of $2,015-million and a pretax internal rate of return of 28 per cent. The expansion case is based on probable mineral reserves, with the remainder being inferred mineral resources. Inferred mineral resources are considered too geologically speculative to have economic considerations applied to them that would enable them to be categorized as mineral reserves. There is no certainty that the production forecasts on which the expansion case is based will be realized.

FS highlights

Robust economics based on 2.5-million-tonne-per-year production over a 34-year mine life

Pretax economics:

• Internal rate of return (IRR) of 23 per cent;
• Net present value (NPV) at 8 per cent of $1,017-million;
• Payback in 4.2 years after commencement of operations;
• Low-cost production -- utilizing a Q3 2023 cost basis of $22.70 per tonne FOB (free on board) originating port.

Expansion of indicated mineral resources and first-time declaration of mineral reserves

Updated mineral resource estimate:

• Indicated mineral resources totalling 383 Mt at 96 per cent NaCl (sodium chloride);
• Inferred mineral resources totalling 868 Mt at 95.2 per cent NaCl;
• Probable mineral reserves totalling 88.1 Mt at 96 per cent NaCl.

Note: The conversion of inferred to indicated mineral resources (and subsequent conversion to probable mineral reserves) has been limited by the target of an initial 34-year mine life. It is anticipated that further upgrading of mineral resources to mineral reserves will be carried out from underground during the production phase.

• Key elements of the project are designed to accommodate mine and processing expansion of up to four Mtpa and to extend the mine life beyond 34 years.
• Great Atlantic would stand out as a low-cost producer and the first major underground salt mine in North America designed to be accessible by declines as opposed to shafts.
• Designed to minimize environmental impact by utilizing electrified equipment.

Rick LaBelle, Atlas chief executive officer, commented: "I am thrilled to be joining the company at this pivotal point in its history. The independent feasibility study is a major milestone on the path to the development of the massive high-grade Great Atlantic deposit which will stand out as the salt mine of the 21st century in North America, strategically located in the heart of a robust salt market serving Eastern Canada and the U.S. East Coast."

Mr. LaBelle added: "I'm excited to be working with president Rowland Howe, who played such an important role in the development of the world's largest underground salt mine at Goderich, and we're in the midst of assembling a top-notch team to get the job done at Great Atlantic. The expansion scenario underscores how there is substantial additional room to optimize an already strong feasibility study. We have derisked this project and we will maximize the value of this unique, transformative asset for shareholders in an investor-friendly way."

Mr. LaBelle concluded, "I look forward to a very busy Q4 as we build momentum and, accordingly, I expect Atlas Salt will have much more to announce."

FS technical summary

Overview

The FS considers developing Great Atlantic into an underground operating mine capable of producing 2.5 Mtpa of rock salt with key mine access and plant infrastructure designed for four Mtpa. Construction of the mine would occur over three years, with access to the deposit via twin declines. Extraction of rock salt would occur using the room and pillar method, with continuous mining equipment. Salt would be processed to a specific size and grade using a crushing and screening plant located within the underground mine, and then brought to surface via conveyor belts. An overland conveyor would transport the rock salt from the mine area to the existing Turf Point port for loading onto ships destined for Canadian and American markets. The FS builds upon the Jan. 30, 2023, PEA and will form the basis for environmental licensing and permitting and the next phase of engineering design.

Mineral resources

Canadian Institute of Mining, Metallurgy and Petroleum (CIM) definition standards for mineral resources and mineral reserves were used for mineral resource classification. The updated mineral resource currently includes 383 Mt of indicated mineral resources plus 868 Mt of inferred resources. The attached table provides a summary of the Great Atlantic mineral resource estimate prepared by SLR, with an effective date of May 11, 2023. The results from the Jan. 30 PEA are shown for comparison.

The qualified person is not aware of any environmental, permitting, legal, title, taxation, socio-economic, marketing, political or other relevant factors that could materially affect the mineral reserve estimate.

Mining and mineral reserves

Mining designs, development plans and schedules have been prepared for a fully electric, mechanized room and pillar mining operation. It is envisaged that salt will be mined using continuous miners and hauled by truck to a lump breaker and conveyor system to move material to a crushing and screening plant located underground. The FS is based upon the initial production of 2.5 Mtpa of rock salt product with key mine infrastructure capacity to expand to four Mtpa. A summary of mineral reserves, effective July 31, 2023, is shown herein.

The QP is not aware of any environmental, permitting, legal, title, taxation, socio-economic, marketing, political or other relevant factors that could materially affect the mineral reserve estimate.

The mine will be accessed through two declines driven to the 240 Level (nominally 240 metres below surface) where the process plant and related infrastructure will be located. One decline will provide fresh air into the mine and be used for vehicle access, while the other will exhaust air and contain an overhead conveyor to transport finished rock salt product to surface. Twin declines will be extended from the 240 Level to the first production level at the 320 Level, continuing deeper into the mine as each new production level gets established. The primary mine-related infrastructure including maintenance shops, vehicle charging bays and gear storage will be located on the 320 Level.

Internal declines will be developed as necessary to sustain the initial production rate of 2.5 Mtpa over an initial 34-year mine life. A total of seven production levels supported with internal declines and level-specific infrastructure will be constructed to support mining activities on each level. Room and pillar production mining will be executed in four cuts of five metres height, resulting in a maximum room height of 20 m. Rooms will be 16 m wide, separated by 25 m square pillars.

All major equipment used in the mine will be battery electric or plugged electric, with minimal diesel-powered equipment in the mine.

Processing

Processing of the salt will take place at a crushing and screening plant located within the underground mine. The rock salt produced will be suitable for use as a deicing product, conforming to specification ASTM-D632, with a minimum NaCl grade of 95 per cent and certain grading sizes. Excess fines produced during the crushing and screening process will be used within the mine for haulage way surfacing. There are no chemical processes or reagents involved in the production of rock salt, other than an anti-caking agent that is added to the product immediately before shipping. After rock salt has been processed, it will be transported to the surface via conveyor belts. On surface, a series of conveyor belts will transport the rock salt from the mine site to the port.

Infrastructure

The Great Atlantic operation will include both on-site and off-site infrastructure. On-site infrastructure has been configured to minimize the mine site surface footprint. Components of the on-site infrastructure include:

• Site terrace;
• Lined and covered temporary salt storage area used during initial excavations;
• Boxcut and decline access area;
• Surface buildings such as administration, warehouse, fuel bay, dry facility, maintenance shop;
• Salt storage building and associated material handling system;
• Electrical substation and distribution;
• Surface water management system;
• Gatehouse and fencing.

Notably, a tailings management facility is not required for the project, as all material that is processed will be sold as rock salt or remain in the mine as fines.

Off-site infrastructure has been designed to take advantage of some of the existing facilities available in the immediate area, including the port, historical haul road and an NL Power electrical substation. From PEA to FS, the design of elements for the off-site infrastructure has been improved based on discussions with stakeholders.

Planned off-site infrastructure includes the following:

• Improved site access road alignment overland conveyor connecting the mine to the port;
• Retrofitting of the existing port facilities to handle rock salt;
• Addition of a new building and material handling system at the port to expand the capacity of covered material storage;
• High-voltage transmission line connection to NL Power's substation located in the town;
• Sewer and water connection to town utilities.

Environment and community engagement

Environmental base line studies of the project area have been completed by GEMTEC Consulting Engineers and Scientists Ltd. throughout 2022 in preparation for the registration of the project under the environmental review process. Consultations with local community and affected groups are continuing. Atlas has retained the services of an experienced communications consultant to assist and facilitate informed community input into the project development. With the FS now concluded, Atlas intends to launch into the formal environmental assessment process.

Marketing and logistics

As part of the FS, Atlas and SLR have commissioned multiple independent assessments of marketing and logistics. These independent assessments have formed the basis of the assumptions used in the FS.

Rock salt produced from Great Atlantic will initially target the regional deicing markets in Eastern Canada and the United States East Coast. It is estimated that this market requires between 11 Mtpa and 16 Mtpa of rock salt in any given year, sourced from domestic and international suppliers, with the demand highly correlated to weather conditions. The primary customers of rock salt are government entities which use a tender system for the annual supply of deicing salt. Secondary customers include commercial deicing operators.

Government entities include municipalities, departments of transportation (DoT), counties, and other provincial or state entities, while commercial operators may vary from distribution companies for retail purchase, or contractors which purchase rock salt for deicing commercial and private properties.

Cash flow model basis

SLR has prepared a cash flow model that is based on a 34-year mine plan with a production rate of 2.5 Mtpa. It is noted that the mineral resource base will allow for a much longer mine life. The mine schedule includes a three-year ramp-up period, with year one production of 1.5 Mtpa, year two production of two Mtpa and year three reaching steady-state production of 2.5 Mtpa.

The cash flow model comprises estimates of capital costs, operating costs, an assessment of revenue and estimate of project economic metrics, such as net present value, internal rate of return and payback period. Economic metrics were assessed both on a pretax and posttax basis.

SLR has assumed that if preconstruction activities commence in 2024, construction of the mine would commence in 2025, with salt production commencing in 2028. To bring salt prices to a 2028 base date, SLR has applied a 4-per-cent annual increase to the price of salt, which is consistent with other publicly available technical reports on existing salt operations in North America. Beyond 2028, SLR has applied a 2-per-cent annual increase to the price of salt. In terms of costs, SLR has applied 2-per-cent annual inflation to capital and operating costs. SLR has also applied a 2-per-cent premium to prices every fifth year, to account for volatility in the rock salt markets due to weather events.

Capital costs

Capital costs for the project have been estimated based on first principles buildups, factored estimates, and quotes for major equipment and supplies. The capital cost estimate conforms to an AACE Class 3 estimate, as of the third quarter (Q3) of 2023. Capital costs are divided between preproduction capital (representing years leading up to salt production) and sustaining capital. Costs are divided into areas including mining, processing, infrastructure, off-site infrastructure, indirect costs, owner's costs and contingency. The capital cost estimate is presented herein.

Operating costs

Operating costs for the project have been estimated based on first principles buildups, estimations of labour quantities and remuneration, productivity, and consumption assumptions. The operating cost estimate is as of Q3 2023. Operating costs are divided into disciplines including mining, processing, general and administration, and port operations. SLR has assumed that the port would be owned and operated by a third party and accessible based on commercial terms. The operating cost estimate is presented herein.

Pricing and revenue assumptions

SLR has assumed a weighted average price of rock salt based on a market analysis review completed by a third party, as well as taking into consideration the shipping and logistics costs of getting the salt to destination ports. SLR's revenue analysis is based on pricing FOB Turf Point and is based on Q3 2023. The project is subject to a royalty payable to Vulcan Minerals Inc., in the amount of 3 per cent of net production revenue. A summary of revenue assumptions is presented herein.

Economic outcomes

The resulting economics of the project including net present value (NPV) and internal rate of return (IRR) are presented herein. Results from the Jan. 30 PEA are shown for comparison purposes.

It is noted that all calculations of NPV and IRR assume an initial capital spending period of four years. The payback period calculations have a base date of the commencement of operations.

Expansion case to four-million-tonne-per-year production

In addition to the FS case of 2.5 Mtpa, SLR has prepared a preliminary economic assessment for a scenario comprising expanded production at a rate of four Mtpa. The mine plan for the PEA is based upon extraction of 193 million tonnes, consisting of the mineral reserves defined in the FS plus indicated and inferred mineral resources from the 320 Level to the 530 Level. The mine life is 47.5 years, with significant unmined inferred resources remaining.

The mining designs contained in the PEA are based, in part, on inferred mineral resources. Approximately 46 per cent of the mine plan is based on probable mineral reserves, with the remainder being inferred mineral resources. Inferred mineral resources are considered too geologically speculative to have economic considerations applied to them that would enable them to be categorized as mineral reserves. There is no certainty that the production forecasts on which the PEA is based will be realized.

The major difference from the FS case is the addition of three more continuous miners (total of five plus a roadheader) and up to seven additional haul trucks. In the preproduction and early years of production, development is accelerated in order to access more workplaces.

The results of the PEA economic analysis are shown herein.

Next steps

Upon completion of the FS, Atlas intends to release a supporting National Instrument 43-101 technical report filed on SEDAR+ within 45 days of this news release. Other continuing work toward advancing the project includes the following:

• Ramp-up of owner's team to advance the next phases of engineering;
• Initiation of formal environmental approvals process;
• Review of recommended field programs that could further derisk the project;
• Continued engagement with stakeholders and first nations groups;
• Continuing discussions with potential vendors and suppliers.
