In this historically high gold price environment, we need to rapidly advance the project. The current plan has a shorter payback than the previous plan and allows us to consider expansion options after payback has been achieved.

I would like to thank everyone who contributed to the completion of this study, as well as our employees, stakeholders, and shareholders for their continuous support. I believe Wallbridge has a bright future, and we look forward to taking the necessary steps to increase value for our shareholders.”

Table 1: PEA Summary of Key Metrics and Project Economics

1. Total cash costs per ounce are operating costs, composed of mining (UG and OP), processing, water treatment and tailings, minesite G&A and royalty costs, divided by payable gold ounces.

2. AISC/oz includes operating costs, sustaining capital expenditures to support the on-going operations, and closure costs, divided by payable gold ounces.

3. Non-IFRS financial measures with no standardized definition under IFRS. Refer to note at end of this news release.

Financial Analysis

The PEA assumes a base case gold price of US$2,200/oz. Using that base case assumption, the Project generates an after-tax NPV of $706 million using a 5% discount rate and an after-tax IRR of 21%.

The Project generates cumulative free cash flow of $1,367 million and averages annual free cash flow of $120 million over a mine life of 16 years (Figure 1). Total taxes payable over LOM at the base case gold price is $776 million.

Figure1.AnnualAfter-Tax Free Cash Flow (millions)

Sensitivities

The PEA financial economic analysis is significantly influenced by gold prices. At a gold price of US$3,000/oz and FX of CAD$:US$ of 1.35:1.00, the Project generates an after-tax NPV of $1,381 million and an after-tax IRR of 34% with a payback period of 2.4 years from the start of commencement of production (Table 2).

Mineral Resource Estimate

The updated mineral resource estimates (“MRE”) for the Fenelon and Martiniere deposits presented in this news release were prepared by Mauro Bassotti, P.Geo., an independent mineral resource consultant using all available information. The effective date of the 2025 MRE is March 20, 2025. The databases supporting the 2025 MREs are complete, valid and up to date, with close-out dates of October 22, 2024 and January 8, 2025 for Fenelon and Martiniere respectively. The 2025 Mineral Resource Statement for the Detour-Fenelon Gold Trend Property is presented below in Table 6. The statement provides the consolidated estimates for the Fenelon and Martiniere deposits. Details are provided in Item 14 of the PEA technical report.

Table 6: Detour-Fenelon Gold Trend Property 2025 Mineral Resource Statement by Deposit

Notes to accompany the Detour-Fenelon Gold Trend Property 2025 Mineral Resource Statement:

1. The effective date of the 2025 MREs is March 20, 2025.

2. The 2025 MREs follow CIM Definition Standards (2014) and CIM MRMR Guidelines (2019).

3. The qualified person (“QP”) for the 2025 MREs is Mr. Mauro Bassotti (P.Geo.) who is an independent mineral resource consultant.

4. The criterion of reasonable prospects for economic extraction has been met by having constraining volumes applied to estimated blocks using GEOVIA Whittle pit optimizer (“Whittle”) software for open pit mineral resources and using Deswik Stope Optimizer (“DSO”) software for underground mineral resources, and by the application of cut-off grades appropriate to the potential mining extraction scenario (i.e., open pit, underground long-hole, underground cut-and-fill). Constraining 3D Whittle open pit and DSO underground stope volumes have been generated based on a gold price assumption of US$2,150 per troy ounce. A minimum mining width of 2.0 m was used for underground stope optimization.

5. The potentially economic open pit shells and underground DSO shapes used for reporting the 2025 MREs have been generated by Mr. Simon Boudreau (P.Eng.), Senior Mining Engineer for InnovExplo Inc., a member of Norda Stelo Inc.

6. For the Fenelon deposit, sixteen (16) mineralized domains and four (4) surrounding alteration envelopes were modelled in 3D to the true thickness of the mineralization. Supported by measurements, a density value of 2.80 g/cm³ was applied to blocks inside mineralized domains and 2.81 g/cm³ to blocks inside alteration envelopes. High-grade capping was applied to raw assay data and established on a per-zone basis, ranging between 7 g/t Au and 100 g/t Au for the mineralized domains, and a fixed capping value of 10 g/t Au for the alteration envelopes. One-metre (1.0 m) sample assay composites were calculated within the mineralized domains and alteration envelopes using the grade of the adjacent material when assayed or a value of 0.001 when not assayed.

7. For the Martiniere deposit, sixteen (16) mineralized domains and ten (10) surrounding alteration envelopes were modelled in 3D to the true thickness of the mineralization. Supported by measurements, the mean density value of the domain was applied to the blocks inside mineralized domains and alteration envelopes, with density values ranging from 2.80 to 3.09 g/cm³. High-grade capping was applied to raw assay data and established on a per-zone basis, ranging between 15 g/t Au and 100 g/t Au for the mineralized domains, and a fixed capping value of 5 g/t Au for the alteration envelopes. 1.0 m composites were calculated within the mineralized domains and alteration envelopes using the grade of the adjacent material when assayed or a value of 0.001 when not assayed.

8. The cut-off grades for the Fenelon deposit were calculated using a gold price of US$2,250/oz; a USD/CAD exchange rate of 1.35; a refining cost of $5.00/t; a processing cost of $30.00/t; a mining cost of $5.75/t (bedrock) or $5.95/t (overburden) for the surface portion; a mining cost of $90.00/t for the underground portion; and a G&A cost of $10.00/t. A metallurgical recovery of 95.0% and royalty of 4.0% were applied to the cut-off grade calculations.

9. The cut-off grades for the Martiniere deposit were calculated using a gold price of US$2,250/oz; a USD/CAD exchange rate of 1.00:1.35; a refining cost of $5.00/t; a processing cost of $30.00/t; a mining cost of $5.75/t (bedrock) or $5.95/t (overburden) for the surface portion; a mining cost of $125.00/t for the underground portion using the long-hole mining method (“LH”), a mining cost of $135.00/t for the underground portion using the cut-and-fill mining method (“CF”); and a G&A cost of $10.00/t. A metallurgical recovery of 85.0% and royalty of 2.0% were applied to the cut-off grade calculations. The metallurgical recovery is based upon a metallurgical characterization study completed in December 2024 (SGS, 2024; Wallbridge news release dated December 19, 2024).

10. Tonnage estimates are reported to the nearest 1000 tonnes (000’s). Contained gold estimates are reported to the nearest 1000 troy ounces (000’s).

11. These mineral resources are not mineral reserves as they do not have demonstrated economic viability.

12. The QP is not aware of any known environmental, permitting, legal, title-related, taxation, sociopolitical or marketing issues, or any other relevant issue, that could materially affect the potential development of mineral resources other than those discussed in the 2025 MREs.

13. Results are presented in situ. Ounce (troy) = metric tons x grade/31.10348. Any discrepancies in the totals are due to rounding effects; rounding followed the recommendations as per NI 43-101.

The reader should note that the 2025 PEA does not include the Martiniere deposit mineral resource estimate.

Mining

The mine will have a production rate of 3,000 tonnes per day (“tpd”) over a 16-year LOM.

A total of 16.6 Mt of mineralized material at an average grade of 3.34 g/t will be extracted from three different mining zones:

1. Contact-Tabasco-Cayenne (“C-T-C”), with 54.6% of the ounces to be mined;

2. Area 51, with 44.9% of the ounces to be mined; and

3. Gabbro open pit, with 0.5% of the ounces to be mined.
   

The mining method will be long hole with longitudinal stopes measuring 5 to 8 m wide, corresponding to 44% of the stope tonnage. Transverse stopes are designed for stopes 8 to 15+ m wide, which account for 56% of the remaining stope tonnage.

Stope dimensions are 30 m (Area 51 zone) to 40 m (C-T-C zones) high, 5 to 15 m wide, and 20 m long. The average stope size in all zones is approximately 15,000 t. An average of 70 stopes will be mined annually. Mining recovery is estimated at 95%. Stope backfilling will be done mostly with paste backfill (66%) or cemented rock fill (2%) or rock fill (32%), depending on the stope dimensions and sequence.

A mining contractor will carry out development during pre-production. Starting in pre- production Year -1, the development will be done with the owner’s equipment and personnel. The priority is to develop the main C-T-C ramp and access production horizon.

The mining fleet, comprised of a maximum of 66 pieces of mobile equipment, will be purchased via a financing agreement. Supporting underground infrastructure includes two ventilation intake raises and heating systems, and one exhaust raise.

Figure 3. Overview of the Fenelon Project on a Longitudinal View Looking North 

Metallurgy

The main metallurgical testwork program was conducted in two phases, in 2020 and 2021, on material from the Area 51 and C-T-C zones by SGS Canada Inc.

Grindability testing, including semi-autogenous grinding (“SAG”) mill comminution testing, was completed in 2021. The samples were characterized as hard in terms of resistance to impact breakage during the SMC test, with A×b drop weight test values ranging from 23 to 31. The Bond rod mill work index results ranged from 15.6 to 16.9 kWh/tonne, classifying the material as moderately hard to hard. The Bond ball mill work index ranged from 13.4 to 16.2 kWh/tonne, indicating a medium hardness range.

Gravity gold recovery testing was performed in 2021 on a representative composite sample from the C-T-C and Area 51 zones. The testwork results for E-GRG (Extended Gravity Recoverable Gold) showed gold recoveries of up to 82% for the Contact zone and 90% for the Area 51 zone, aligning with the results from prior testing conducted in 2020. These findings confirm the necessity of incorporating a gravity circuit in the process flowsheet.

Cyanidation testing was conducted in 2020 on representative samples following gravity recovery. Overall gold recoveries ranged from 94.6% to 96.9% for the C-T-C zones and from 95.3% to 97.1% for the Area 51 Zone.

Based on the metallurgical testwork conducted in 2020 and 2021, and considering the planned process flowsheet, the estimated average payable gold recovery for the process plant is expected to be 96.0% over the LOM.

Processing

The process plant is designed to treat a total of 3,000 tpd of material. It will incorporate a SAG mill operating in closed circuit with a pebble crusher, and a ball mill in closed circuit with cyclones, forming a Semi-Autogenous Ball Mill Crusher circuit.

Gold recovery will be achieved through a leaching circuit. The cyclone overflow will be processed through a pre-leach tank, followed by a seven-tank carbon-in-leach (“CIL”) circuit and an SO₂/Air cyanide destruction system. Gold will be recovered via an adsorption-desorption-recovery circuit using the Zadra process, followed by electrowinning cells. The final gold product will be refined in the gold room, where gold bars will be produced and subsequently shipped to facilities for purification.

The SO₂/Air cyanide detoxification circuit will be followed by a tailings flotation circuit, where the sulphide concentrate will be utilized for paste backfill to be sent underground and/or non sulphide to produce dried tailings for tailings storage.

The process plant facility will also include, a mill maintenance workshop, administrative offices, and a dry room.

Project Infrastructure

The Project is approximately 75 km from the town of Matagami. It can be accessed from highway 810 via a 24-km forestry road. The existing Fenelon camp includes a welcome center, a 155-room dormitory, a dry, a kitchen, a dining room, a game room, a workshop and a First Nations cultural centre.

The existing camp and mine site include a core shack, modular offices, a garage, a water treatment plant, an air ventilation-heating system to serve the underground openings, an open pit and a portal connecting to an underground ramp. The camp and mine site are served by diesel generators for electricity production. All these facilities will be used at the start of the Project and will be upgraded, expanded or replaced during construction and operations.

The mining and processing infrastructure will be located on the Fenelon site. The Project envisions the upgrade of existing surface infrastructure: site access road, potable water and sewage systems, underground mine portal, mine ventilation systems (intake and exhaust), main and remote gatehouses, surface maintenance shop, waste rock stockpile, overburden stockpile, and mineralized material stockpile. The Project will require construction of the following infrastructure items: 3,000 tpd process plant complex, paste plant, offices, dry, truck shop and warehouse; 4 km of new 120kV overhead transmission line from the connection point to HydroQuebec up to a new 120-69 kV substation; from this point, a new 69kV overhead line will run for 22 km up to the new site substation (69kV-25kV); final effluent water treatment plant; surface water management facility, including ditches, pond and pumping stations; service and haulage roads; and tailings management facility.

The camp will be expanded to 250 rooms with associated kitchen, dining room and game- exercise room. A local office is planned in a nearby town to support administration, communication, human resources and technical personnel.

Underground Infrastructure

The main ventilation intake is a 4 m diameter raise bored from L-270 to the surface in two sections, serving as the primary fresh air intake with high-efficiency surface fans. Exhaust air will exit mainly through the main ramp.

Underground infrastructure includes a service bay on L-520, which will accommodate a welding bay, garage, tire storage, washing bay, small warehouse, greasing bay, fuel bay, and parking. The garage will allow for simultaneous maintenance of two large equipment units and one smaller unit, ensuring efficient underground operations.

Underground refuge stations are strategically located within 1,000 m to ensure accessibility.

Mine dewatering will be managed through separate systems for contact and non-contact water. Contact water, collected from groundwater inflow and mine operations, will be directed to three main pumping. Non-contact water will be channeled down to a dedicated pumping station. Each Pumping station will be equipped with three centrifugal pumps (two in operation, one on standby).

Pump stations and powder magazines are not explicitly included in the design but have been accounted for in the equivalent meter contingency, with associated costs incorporated into the financial model.

Tailings and Waste Rock Management

Tailings from mill operations will be managed in two streams: used as underground paste backfill or disposed on the surface as filtered tailings in a dry stack facility (85% solids). Tailings will be pumped either to the paste backfill plant (via the filter plant for pre- processing) or to a filter plant before being trucked to the tailings storage facility (“TSF”).

The selection of the site for surface tailings disposal was advanced in previous studies. The proposed site is located 1.0 km northwest of the mill. In this area, the topography is relatively flat, and the site is surrounded by a natural stream, a conceptual high-water mark was outlined. The perimeter of the facility’s footprint was placed at 30 m from the conceptual line.

Given the low potential for acid mine drainage and metal leaching of the surface tailings facility, the current design, as proposed, is not lined. It is noted, however, the geochemical testing is ongoing and should the addition of the membrane be required this can increase costs significantly and should be included, in such a case, in future designs. It is further noted that Wallbridge has elected to include a desulphurization plant, with the residual sulphur content being below the threshold limits of the new Directive 019. All things considered this study has not included a membrane to encapsulate the tailings.

The paste mixer is a horizontal twin shaft mixer with a capacity of 3 m³. In the mixer, the filtered desulphurized tailings are mixed with binder (90/10 slag cement binder was selected from the preliminary uniaxial compressive strength results) and thickened sulphide tailings from the holding tank to form paste backfill. The mixer will be fitted with an adjustable slump water stream to control the density of the paste. After mixing, the paste backfill is pumped to the borehole feeding the underground paste distribution system using one positive displacement piston pump.

As conceptualized, all development waste rock will be used to fill underground voids at some point in the mine life. A portion of the material will have to be temporarily stored on surface, while stopes are being mined out. The limited geochemistry available has indicated that the development waste is both PAG and metal leaching. As such this has been considered in the design of the waste pile which will store 0.84 Mm³ of material at its peak.

Water Treatment

All contact water, including groundwater, surface runoff and tailings and waste rock storage facilities drainage shall be collected and treated at the water treatment plant before being discharged to the environment.

The water treatment plant (“WTP”) will be located near the TSF water basin. A settling pond will decant solids from the underground dewatering. An MBBR reactor (moving bed biofilm reactor) will remove ammonia and/or other nitrogen-based contaminants present in water from both underground dewatering and TSF. Finally, MBBR-treated water and other contact water containing suspended solids and metals will be removed in a high-rate clarifier by following treatment steps such as metal precipitation, coagulation, flocculation, and clarification. The final effluent from the WTP will be discharged into the environment by gravity, and its quality will be monitored in an effluent quality monitoring station.

Environment and Permitting

In Northern Quebec (James Bay region located south of the 55th parallel), all mining development projects must follow the environmental assessment (“EA”) and review procedures under the Regulation Respecting the Environmental and Social Impact Assessment and Review Procedure applicable to the territory of James Bay and Northern Quebec. With a planned production capacity of 3,000 per day, the mining project does not exceed the 5,000 per day threshold for the federal environmental assessment procedure set out in the Physical Activities Regulations (SOR/2019-285). Therefore, no environmental assessment in compliance with the requirements of the federal Impact Assessment Act (S.C. 2019, c. 28, s. 1) will be required.

The acquisition of baseline environmental knowledge on the Project began several years ago and is still ongoing today. To date, preliminary environmental characterizations of the physical environment and biological environment have been carried out and/or are ongoing. Confirmation of the regulatory context made it possible to identify the scope of the environmental studies required to obtain environmental authorizations. Inventory work is underway to fill these gaps.

To date, no major environmental issues have been identified in the work undertaken. The situation of the woodland caribou, designated as vulnerable in Quebec and threatened at the federal level, remains uncertain to date in the Project area with regard to future legal protection of its habitat.

A preliminary geochemical characterization program has been in progress since 2020 to identify the geo-environmental characteristics of mineralized material and mine wastes and classify their environmental risk (e.g., for acid rock drainage and metal leaching) based on Quebec provincial guidance documents. Findings from the geochemical study have been incorporated into the Project design.

Closure Plan

A closure and rehabilitation plan for the land affected by the Project will be prepared and submitted for authorization. The preliminary concept for site closure is estimated at $11.5 million. The current financial deposit for site closure is estimated at $2.9 million for a net closure cost of $8.6 million.

Non-IFRS Financial Measures

Wallbridge has included certain non-IFRS financial measures commonly used in the mining industry in this news release, such as initial capital expenditures, sustaining capital expenditures, total cash costs and all-in sustaining costs, which are not measures recognized under IFRS and do not have a standardized meaning prescribed by IFRS. As a result, these measures may not be comparable to similar measures reported by other companies. Each of these measures used are intended to provide additional information to the user and should not be considered in isolation or as a substitute for measures prepared in accordance with IFRS. Non-IFRS financial measures used in this news release and common to the gold mining industry are defined below.

Total Cash Costs and Total Cash Costs per Ounce

Total cash costs are reflective of the cost of production. Total cash costs reported in the PEA include mining (UG and OP), processing, water treatment and tailings, minesite G&A and royalty costs. Total cash costs per ounce is calculated as total cash costs divided by payable gold ounces.

All-In Sustaining Costs and All-In Sustaining Costs per Ounce

All-in sustaining costs and all-in sustaining costs per ounce are reflective of all of the expenditures that are required to produce an ounce of gold from operations. All-in sustaining costs reported in the PEA include total cash costs, sustaining capital expenditures, closure costs, but exclude corporate general and administrative costs. All-in sustaining costs per ounce is calculated as all-in sustaining costs divided by payable gold ounces.

A description of the significant cost components that make up the forward looking non-IFRS financial measures of total cash costs and all-in sustaining costs per ounce of payable gold produced is shown in the table below.

Free Cash Flow

Free cash flow was estimated as the amount of cash generated by Fenelon after all operating and capital expenditures have been paid.

Initial Capital Expenditures and Sustaining Capital Expenditures

Initial and sustaining capital expenditures in the PEA were estimated based on current costs received from vendors as well as developed from first principles, while some were estimated based on factored references and experience from similar operating projects. Initial capital expenditures represent the construction and development costs to achieve commercial production and sustaining capital expenditures represent the construction and development costs subsequent to commercial production.
