FORTUNE BAY ANNOUNCES UPDATED PEA FOR GOLDFIELDS, SASKATCHEWAN

Ausenco-led study delivers after-tax NPV of C$1.25 billion at spot gold price; Permitting underway

HALIFAX, NS September 23, 2025 – Fortune Bay Corp. (TSXV: FOR) (FWB: 5QN) (OTCQB: FTBYF)

(“Fortune Bay” or the “Company”) is pleased to announce results from an independent Updated Preliminary

Economic Assessment (“ Updated PEA”) for its 100% owned Goldfields Gold Project (“Goldfields” or the

“Project”) located in northern Saskatchewan.

Updated PEA Highlights:

• Expedited Path to Production: Sub-5,000 tpd open-pit scenario designed to remain within provincial

permitting, leveraging a valid EIS (2008), existing infrastructure, and past-producing status.

• Strong Economics; High-Sensitivity to Gold Price:

Gold Price/oz USD 2,600 (Base Case) USD 3,650 (Spot Price 1)

After-Tax NPV5% C$610M C$1,253M

After-Tax IRR 44% 74%

After-tax NPV5%/CAPEX 2.0 4.2

1. Gold spot price as of September 19, 2025

• Robust Financing Fundamentals: 14-year mine life with 8 96,000 oz payable production; favorable

NPV/Capex ratio; and strong Free Cash Flow (after-tax cumulative C$914M FCF base case; C$1,817M

FCF at US$3,650/oz).

• Low-Cost, Capital Efficient: Attractive operating costs (US$1,207/oz cash cost; US$1,330/oz AISC),

supported by a modest initial capital requirement of C$301M, that includes a C$51M contingency.

• Grade, Recovery, Strip Advantage: Among highest-grade open-pit developments in the Americas 2

(1.2 g/t Mill Head Grade), 95.4% gold recovery, and only 3:1 waste-to-resource ratio.

• De-Risked Pathway: 97% Indicated ounces incorporated in the Updated PEA mine plan, reconciled

with historical production; supported by established infrastructure, well-developed community relations,

and a clear permitting pathway that builds on existing EIS.

• Growth Potential: Resource expansion at Box and Athona plus multiple advanced targets (Frontier

Lake, Golden Pond, Triangle).

• Premier Jurisdiction: Saskatchewan ranks #1 in Canada and #7 globally for mining investment

attractiveness (Fraser Institute, 2024).

“The Updated PEA demonstrates the exceptional economics of Goldfields, establishing it as a significant

development asset within Canada’s gold mining sector, while underscoring the disconnect between the

project’s intrinsic value and Fortune Bay’s market valuation,” commented Dale Verran, CEO of Fortune

Bay. “With 97% of ounces in the mine plan classified as Indicated and supported by extensive historic al

datasets, established infrastructure and a valid EIS, Goldfields is comparatively de-risked for a PEA-stage

project and is uniquely positioned for near-term development. We are now focused on securing additional

permits, advancing key de -risking PFS studies, and preparing for resource -growth drilling. We are also

evaluating alternative options for an accelerated production pathway.”

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 this News Release.

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.

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.

Simplified Process Flowsheet

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 p roject 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.
