CEO Commentary:

"This PEA marks an important milestone for AMEX and reaffirms our view that our fully owned Perron Project is a high-quality asset and has the potential of being a highly profitable stand-alone mining operation with minimal environmental impact" said Victor Cantore, President and Chief Executive Officer of AMEX Exploration. "The Project represents a strong combination of high-margin production and modest capital requirements, with the opportunity for significant resource growth in the future."

"This PEA demonstrates Perron's early potential based on a database close date of June 30th, 2024. Since the closing of the database, drilling has continued at depth and laterally and has already shown excellent high-grade intercepts beyond the currently defined mineral resource. This successful additional drilling demonstrates the continuation of mineralization and the upside potential for further resource and mine life additions in the future as we progress exploration."

1. The PEA is preliminary in nature and is based, in part, on Inferred Mineral Resources. Inferred Mineral Resources are considered too geologically speculative to have the economic considerations applied to them that would enable them to be categorized as Mineral Reserves. There is no certainty that the economic forecasts on which the PEA is based will be realized.
2. The economic analysis of the project was carried out using a discounted cash flow approach on a pre-tax and after-tax basis with a discount rate of 5%.
3. Revenue was based on a long-term gold price of $2,000/oz in USD.
4. Cost estimates were prepared in C$.
5. An exchange rate of 0.74 USD per 1.00 CAD was assumed.

• Underpinned by world class infrastructure, the Perron PEA demonstrates a top-tier high margin gold mining operation in the stable jurisdiction of Quebec, Canada. The Project is located within the prolific Abitibi region, one of the most prolific gold belts in the world.

• The PEA results confirm that Perron has the potential to be a stand-alone and highly profitable operation with an excellent internal rate of return (IRR) and after-tax net present value (NPV) at a range of gold prices.

• The PEA shows that Perron has the potential to be a mine with limited environmental impact, utilizing the mined out open pits to store tailings and therefore avoiding the construction of a tailings management facility.

Mining

The mine will be operated as a mechanized underground operation, which will be complemented by open pit production. The mine will have an overall average production rate of 1,750 tpd of mineralized material over a 10-year production period that is preceded by a 2-year pre-production period.

The selected underground mining method is longitudinal longhole stoping with cemented rockfill. Stope dimensions average 17.5 m in length, 25 m in height, and 5.7 m in width (LOM average) with a minimum mining width of 3.0 m. The different sectors of the mine will be accessed via ramps and drifts to allow the efficient circulation of mobile mining equipment and to satisfy ventilation and emergency egress requirements. Mineralized material will be extracted using a fleet of owner-operated equipment that includes 10 tonne LHDs and 42 tonne haul trucks.

Five open pits are included in the mine plan and utilize conventional truck and shovel mining that will be executed by a contractor. The pits will begin to be mined in the preproduction period, with material completely extracted by year 4 as they are sequenced such that they can be used to manage all tailings generated by the mill.

Figure 1: Mine Design

Table 4: Mine Physicals

Processing

A total of 1,750 tpd of material will be processed in a plant that consists of primary crushing, followed by a grinding circuit consisting of a semi-autogenous grinding mill of 5.5 m diameter x 1.8 m long in an opened circuit and a ball mill of 4.0 m diameter x 6.7 m long in a closed circuit with cyclones - SABC circuit. A gravity circuit followed by leaching will recover coarse gold from the cyclone underflow, while the cyclone overflow, at a P80=74 microns, is treated in a six (6) tank carbon-in-leach circuit, followed by SO2/air cyanide destruction. Gold will be recovered in an adsorption-desorption-recovery circuit and electrowinning cells, with gold room recovery and production of bullion bars.

The CIL tailings after the cyanide destruction will be pumped to a high-rate thickener to increase the slurry density to 62-64 % solid and pumped to empty pits.

The process plant gold recovery is estimated to average 95.0% over the LOM.

The process plant building will include a laboratory, mill offices, a dry and an electrical and mechanical shop.

Infrastructure

The Project is approximately 5 kilometers from the town of Normétal, Quebec and is accessible via a well-maintained forestry road. The Project will require construction of the following supporting infrastructure items: 1,750 tpd process plant complex, offices, dry, maintenance shop and warehouse; gatehouse; 5 kilometers of 120kV transmission lines; 120 kV main substation; final effluent water treatment plant; surface water management facility, including ditches, pond and pumping stations; service and haulage roads; potable water and sewage systems; underground mine portal, mine ventilation systems (intake and exhaust) and waste dump and overburden storage facilities. No camp will be required considering the nearby qualified labor pool.

Figure 5: General site arrangement

Workforce

During the 18-month construction period of the mine, the workforce will peak at approximately 250 people, this is in addition to employees who would be required for open pit and underground mining and G&A.

During steady state operations, the average number of employees (mine, process plant and G&A) is estimated at 164 people, excluding contractors (open-pit mining, contract services, etc.).

Tailings

The tailings storage plan will take advantage of open pits that will be mined in the first half of the mine life. Process plant rejects will be thickened and pumped to the mined-out pits sequentially for permanent storage. Tailings will then consolidate over time and excess water will either be used for processing requirements or discharged to the environment once quality conditions are met. This concept aims to limit the environmental impact of the Perron Project, to limit the risks related to traditional Tailings Management Facility (TMF) stability, to simplify short-term and long-term monitoring and to greatly reduce the capital and operating costs related to tailings management.

Capital Expenditure

The total initial construction capital expenditure ("CAPEX") is forecasted at $229M after accounting for $62M in gold sales revenues (pre-production credits). Capitalized mine development prior to commercial production is expected to be approximately $112M, comprised of $38M related to open pit mining and $74M related to underground mining. The majority of the capitalized open pit mining is driven by the strategic decision to complete the mining of a small open pit in the pre-production period in order to be able to start disposing tailings at the commissioning of the process plant. The construction capital accounts for the site development, water treatment and infrastructure area including a truck shop, warehouse and an administration facility. Additionally, the capital estimate includes $15.1M of EPCM and indirect costs and a contingency of $25M.

Quotations from reputable suppliers were obtained for most of the large and high-cost equipment required for the plant, mine and site infrastructure. For other equipment and supplies, cost estimates were based on comparable projects, historical data or derived through consultants' in-house databases.

Table 6: Capital Expenditure

The sustaining capex ("SUSEX") is estimated to be $238M, including $8M of closure and rehabilitation costs. Underground mining SUSEX is earmarked for mining development, additional equipment, replacement units, and major repairs. Other sustaining capex captures in-pits tailings storage, infrastructures and G&A.

Table 7: Sustaining Capital Expenditure

Operating Costs

Life of Mine (LOM) total operating cost is estimated at US$633 per ounce of gold produced, as summarized below. The LOM total AISC is estimated to be US$807 per ounce of gold produced based on average annual gold production of 101,000 ounces over the 10 years of mine life. This cost structure places the Project in the bottom quartile of the global gold cost curve, which is mostly due to the high-grade nature of the mineralized material and to the simplicity of mining.

Table 8: Operating Costs

Financial Analysis

At base case gold price of US$2,000/oz and exchange rate of 1.35, the Project generates after-tax Net Present Value ("NPV") of $525M using 5% discount rate and an after-tax Internal Rate of Return ("IRR") of 40.2% with a payback period of 1.8 years from the commencement of commercial production. The Project generates cumulative free cash flow of $767M and average annual free cash flow of $100M over the 10 years production period. Total taxes payable over LOM at the base case gold price is $566M.

Figure 7: After-Tax FCF

The PEA financial economic analysis is significantly influenced by gold prices. At spot prices of US$2,600/Au oz and exchange rate of 1.39, the Project generates an after-tax NPV of $914M and an after-tax IRR of 59.7% with a payback period of 1.2 years. A sensitivity analysis was performed on the gold price, CAPEX, overall OPEX and exchange rate.

Permitting and Environment

The opening and operation of a mine that has a production capacity equal to or less than 2,000 tonnes per day is not subjected to an environmental impact assessment ("EIA") according to chapter Q-2 of the Environmental Quality Act ("EQA") for the emission of a ministerial decree. As modelled in the PEA, the Perron Project would therefore not submit to processes of and EIA and to the Bureau d'audiences publiques sur l'environnement (''BAPE''), as per current regulation, as the estimated production of 1,750 tonnes per day is below the threshold. However, an application for a ministerial authorization will need to be submitted to the Ministère de l'Environnement, de la Lutte contre les changements climatiques, de la Faune et des Parcs (''MELCCFP''). Studies will be required as part of this application including, hydrological studies, hydrogeological and geochemical analysis, soil quality analysis, surface water, groundwater and sediment quality, characterization of the natural environment, including water bodies, wetlands, species with special status and wildlife inventories for certain species.

The acquisition of baseline environmental knowledge on the Perron property began several years ago and is still ongoing today. An environmental scoping study has been carried out, and to date, no major environmental issues have been identified in the work undertaken. Additional environmental work is planned to be carried out in 2025 such as a geochemical characterization program, various environmental inventories and social engagement with the local stakeholders.

Stakeholder Engagement

The aboriginal community concerned by Amex's activities is the Abitibiwinni First Nation which is an Algonquin First Nation residing primarily in the community of Pikogan in the Abitibi-Temiscamingue region. The Pikogan community, also called Abitibiwinni, is located three (3) kilometers from the town of Amos on the west bank of the Harricana River. The Perron project is located on a part of the ancestral territory of the Algonquin Anishinabeg Nation. A relationship of trust and respect has been built with the Abitibiwinni First Nation Council over the years by demonstrating transparency and consideration. With respect to local communities near the project, Normétal, Valcanton and Saint-Lambert are the main municipalities surrounding the Perron project.

Amex has always prioritized engaging stakeholders and implementing communication and consultation plans. Communication plans include a summary of the work completed on the property every six months as well as the company's orientations for the coming months.

Active participation in the communities through sponsorship, investment, etc. is part of AMEX's core values and aids in fostering good long-term relationships. AMEX will continue consulting, supporting and informing all stakeholders at all stages of the project development.

Exploration Update

The PEA was based upon the Mineral Resource Estimate ("MRE") for which the drill database was closed on June 30, 2024 (please see press release dated September 5, 2024). Since this date, Amex has drilled approximately a further 28,000 m on the Perron Property. This drilling has been demonstrating the growth potential that exists across several zones at Perron.

The Company has displayed in recent months that the High Grade Zone ("HGZ") is open not only at depth but also remains open in certain areas close to surface. The Denise Zone has fantastic potential for expansion in multiple directions, which is significant given its proximity to the HGZ. The latest press release (dated November 6, 2024) showed the growth potential of several zones and that exceptionally high-grade gold can be found across the entirety of the Perron Property.

Since obtaining the MRE, the Amex Exploration team has been optimizing drill planning to target expansion of the open pit and underground stope shapes identified in the resource. Numerous areas across the project have been outlined for expansion due to a lack of drilling. With the PEA now in hand, drill planning will be further refined to prioritize the growth of economic ounces and importantly identify where additional tonnage can be added to the earlier years of the mine life to further enhance the mine's optimization.

Figure 8: Example (from the HGZ) to display that drilling completed after the database cutoff of June 30, 2024 has the potential to add economic stopes to the existing resource (Assays from PE-24-797 fall outside current PEA stopes)

Mineral Resource Estimate

The Perron Project hosts mineral resources as detailed in the NI 43-101 compliant Mineral Resource Estimate with an effective date of September 5, 2024, which can be found on SEDAR+. The mineral resources that have flowed to the mine plan are contained within five different zones (High Grade, Denise, Gratien, Grey Cat and Team) over a strike length of 2,900 meters and span from surface to a depth of approximately 1,400 meters. Each zone is characterized by multiple tabular panels, which mainly trend ENE and dip vertically to sub-vertically.

Table 11: Summary of Mineral Resources

1. The mineral resource estimate is compliant with CIM 2019 standards and guidelines for reporting mineral resources and reserves.
2. Resources are presented undiluted and in situ and are considered to have reasonable prospects for economic extraction. The resources at surface are constrained by pit optimization surfaces and the underground resources are constrained by mineable shapes.
3. The database comprised a total of 1,533 drill holes for 547,361 metres of drilling (which includes historical drilling completed by previous operators) in the extent of the mineral resource, of which (312,051.20 metres) 264,462 samples were assayed as of June 30th, 2024, grid spacing are variable (The Genesis file is Amex_24 Aout 2024_MR.gnft and where the database file is BD_AMEX_08 Jul 2024_MR.accdb).
4. All NQ core assays reported by AMEX were obtained by analytical methods described below under "QA&QC".
5. Geological interpretation of the deposits was based on lithologies, mineralized zones orientation and the mineral observations. Each zone has its own characteristic of mineral occurrence and amount of free gold.
6. Interpretation was initially made from cross-sections at intervals, and then completed in GENESIS, a modelling software, where selections of mineralization intervals were combined to generate mineralization wireframes. Envelopes are generally subvertical with various plunges.
7. The mineral resource estimate encompasses a total of 189 envelopes, sub-vertical gold-bearing envelopes/domains each defined by individual wireframes with a minimum true thickness of 2.0 metres.
8. Samples were composited within the mineralization envelopes into 1.0 metre length composites. A value of zero grade was applied in cases of core not assayed.
9. High grade capping was done on composite data and established using a statistical analysis on a per-zone basis for gold. Capping varied from 5 g/t Au to 200 g/t Au and was applied on composites within each specific envelope.
10. Density values were applied on the different mineralized zones (t/m3) varied from 2.67 to 2.83 from core measurement.
11. Inverse distance squared grade estimation is used. The trial of Ordinary Kriging (OK) was rejected due to smearing and non-effective representation of high-grade areas.
12. Most of the estimates are based on a block dimension of 2m North, 2m East and 2m height and estimation parameters determined by variography. The High-Grade zone has blocks of 2.5m East x 5m Z (Elevation) x 0.5m North.
13. Estimates use metric units (metres, tonnes and g/t). Metal contents are presented in troy ounces (metric tonne x grade / 31.10348).
14. GoldMinds is not aware of any known environmental, permitting, legal, title-related, taxation, socio-political or marketing issues, or any other relevant issue not reported in the technical report, that could materially affect the mineral resource estimate.
