RPX Gold Inc. Delivers Robust Preliminary Economic Assessment and Updated Mineral Resource Estimate for Wawa Gold Project

RPX Gold Inc. (“RPX Gold” or the “Company”) (TSXV: RPX) is pleased to announce the results of a Preliminary Economic Assessment (“PEA”) for its 100%-owned Wawa Gold Project (the “Project”) located in northwestern Ontario, Canada. The PEA was prepared by DRA Americas Inc. (“DRA”), in accordance with National Instrument 43-101 Standards of Disclosure for Mineral Projects (“NI 43-101”). All amounts are in Canadian dollars, unless otherwise stated.

The PEA outlines a phased development plan beginning with open pit mining of near surface mineralization followed by underground mining. The Project has been evaluated at a life of mine (“LoM”) average of 2,000 tonnes per day (“t/d”) of Run of Mine (“ROM”) and demonstrates strong economics using a long-term gold price of US$3,500/oz (the “Base Case”), and enhanced economics using a long-term gold price of US$4,500/oz (the “Upside Case”). Readers are cautioned that at this time no production decision in respect of the Project has been made. Any such decision will be dependent on further exploration and the preparation of a feasibility study which has not been completed, as well as other factors.

The PEA is supported by an updated mineral resource estimate (“2026 MRE”), which resulted in a 48% increase in indicated ounces of gold (compared to the 2024 MRE announced on September 4, 2024), showing improved confidence in the estimation upon which the PEA is based. The 2026 MRE is inclusive of an open pit- and underground mineral resource, prepared by WSP Canada Inc. (“WSP”).

Michael Michaud, President and CEO of RPX Gold commented: “The PEA marks a significant milestone for RPX Gold, outlining an expedited, phased development plan, transitioning from open pit to underground mining, with a low-capital path to the first stage of gold production. This mining scenario leverages existing infrastructure and nearby milling capacity that potentially eliminates the need for a mill or tailings facility, streamlining both permitting and construction. The PEA validates the Wawa Gold Project as a highly attractive development opportunity with substantial exploration upside. In the event a production decision is made, the low risk, staged development approach provides an opportunity to generate cash flow from the initial open pits to be used to further explore and develop the larger mineral resource.”

Project Economics

The financial highlights of the Wawa Gold Project are presented in Table 01.

Production Highlights

The production highlights of the Wawa Gold Project are presented in Table 02.

Table-02: Production Highlights

Cautionary statement: Readers are cautioned that a PEA is preliminary in nature, it includes inferred mineral resources that are considered too speculative geologically to have economic considerations applied to them that would be enable them to be categorized as mineral reserves, and there is no certainty that the PEA will be realized. In addition, the assumption that toll milling will be utilized for processing the material requires agreement with a third-party, which has not been obtained.

The Base Case free cash flow (after-tax) and cumulative cash flow (after-tax) profile is shown in Figure 01, which illustrates the impact of capital expenditures on these parameters.

Economic Sensitivities

A sensitivity analysis was carried out, using the Base Case as a starting point, to assess the impact of changes in the price of gold, total capital expenditures (“Capex”) and operating expenditures (“Opex”) on the Project’s net present value (“NPV”) at a 5% discount rate and internal rate of return (“IRR”). The impact of each variable is examined individually with an interval of ±30% and increments of 15% applied. The after-tax results of the sensitivity analysis are shown in Figure 02 and Figure 03. The Project is sensitive to the gold price, with lower sensitivities observed to changes in Capex and Opex.

The sensitivities of the key after-tax economic metrics of the Project were also evaluated at specific gold prices. The results of this analysis are shown in Table 03 with the Base Case highlighted.

Table-03: After-Tax Sensitivity of Economic Parameters to Gold Price

Development Strategy and Capital Discipline

The PEA was deliberately designed around a capital efficient, high-margin development strategy intended to generate early free cash flow, reduce execution risk, and position the Project to become self-sustaining at an early stage of development.

The mine plan prioritizes easily accessible near-surface mineralization in the early years using an elevated cut-off grade strategy, followed by underground production, while leveraging existing regional infrastructure and toll milling potential. This approach significantly reduces upfront capital requirements by avoiding the construction of a standalone processing facility, resulting in an initial Capex of approximately $51 million, which is materially lower than comparable projects.

With a strong projected cash flow profile with C$303 million cumulative after-tax cash flow net of capital expenditures in the first 5 years of production, rapid payback, and high internal rates of return, the Project is expected to fund ongoing underground development, exploration, and future optimization to reduce reliance on repeated equity financings and thus, shareholder dilution. The Project retains flexibility to scale operations as market conditions permit. Additionally, the Company has available up to C$69 million in tax pool balances that are not reflected in the financial model for the Project.

Importantly, once the Project has achieved steady-state cash flow, the PEA mine plan maximizes the value of the existing mineral resource while preserving substantial upside for future expansion with its demonstrated nearby exploration potential. This phased strategy provides RPX Gold with a clear pathway from development to production while maintaining financial discipline and long-term optionality.

Mineral Resource Estimate

The PEA is supported by the 2026 MRE as presented in Table 04. The 2026 MRE shows a quantity of Indicated mineral resources of 1,244,000 ounces, representing an increase of more than 400,000 ounces (from 842,000 ounces to 1,244,000 ounces), or 48% from the 2024 MRE, while the overall size of the mineral resource remains comparable to the 2024 MRE. This demonstrates a marked improvement in confidence in the mineral resource model supporting the PEA.

The 2026 MRE continues to refer to a small portion of the Company’s land holdings. Numerous historic zones and high priority targets are included in the Wawa Gold Project property and have potential to expand the mineral resource. In both the Jubilee and the Minto deposits, the mineral resource remains open along strike and down-dip.

The 2024 MRE and the 2026 MRE were derived using a 3D block modelling approach, based on Inverse Distance Cubed (ID3) grade interpolation and reported from grade cut-offs and constraining volumes for open-pit (OP) and underground (UG) mining.

Mineral resources are not mineral reserves, and do not demonstrate economic viability. There is no certainty that all, or any parts, of this mineral resource that are the subject of this press release will be converted into mineral reserves. Inferred mineral resources are considered too speculative geologically to have economic considerations applied to them that would enable them to be categorized as mineral reserves.

(Effective Date December 8, 2025)

Mining

The mining methods used for the PEA are conventional open pit mining using truck and shovel followed by underground mining using long hole stoping. The mining schedule assumes one year of pre-production development for the open pits, followed by open pit mining during Years 1 to 3 from a north pit and a south pit, with underground development beginning in Year 2 and underground mining commencing in Year 3 (Figures 04 and 05). The stripping ratio for the open pits is approximately 10:1 given the elevated cut-off grade (0.83 g/t Au) for transporting and processing material at a toll mill. Additionally, wider ramps were designed to allow for larger haul trucks to ensure the 2,000 tonne per day production rate. The lower grade material below the cut-off grade (based on mining and on-site processing costs) will be stockpiled for potential processing in a possible on-site mill in the future, as economics allow.

The main part of the underground mine will be accessed from three portals; two located within the south pit and one within the north pit. Contract mining is assumed to be utilized for both the open pit and underground operations. Therefore, no mining equipment capital costs have been included, as contractor-supplied equipment is incorporated into operating costs over the life of mine. The Capex includes initial capital provisions for mining services, buildings, maintenance facilities, and supporting infrastructure.

Approximately 63% of the ounces in the open pits and 86% of the ounces in the underground mine plan considered in the PEA are in the indicated category, outlining a clear path forward for a drill program required to complete the conversion of inferred ounces (currently included in the mine plan) to indicated in preparation for a pre-feasibility study (“PFS”).

Processing

The gold production profile by year is shown in Figure 06.

The ROM material stockpile will be primary crushed and sampled on site using mobile equipment and placed in a secondary stockpile area for further downstream processing. All crushed material will be transported by highway truck to the selected off-site toll milling facility for processing to produce gold doré bars. Potential toll milling facilities within 150 km are shown in Figure 07). It is assumed that the selected toll milling facility will process material from the Project in the same year as it is mined. There are no current agreements in place with potential toll milling facilities for the Project.

Metallurgical test work completed in 2019 at McClelland Labs Inc. in Reno, NV and at SGS-Lakefield (SGS) in 2025 supports the applicability of conventional cyanidation recovery on Wawa Gold Project mineralogy at a grind size of 80% passing 75 µm. This processing would be deemed conventional and readily processed at various regional mill sites.

For assumed average head grade of 3.2 g/t Au, the modeled gold extraction over a range in arsenic and sulphide contents is estimated at 88% based on test work completed.

Infrastructure

The infrastructure scope includes the primary on-site facilities and supporting infrastructure required to sustain both open pit and underground mining operations (Figure 08). This includes essential site access roads, operational buildings, water management systems, power and utilities, and waste handling infrastructure. Allowance for site access roads is also incorporated, reflecting the development and improvement of road infrastructure required to provide reliable access to the mine site and support the consistent transport of personnel, supplies, and mined material.

The infrastructure scope in the PEA provides for key operational and support facilities required on site, including maintenance, administrative, and service-related infrastructure necessary for day-to-day operations, as well as power transmission and distribution facilities. The PEA also includes allowances for waste management infrastructure to support the safe handling, storage, and management of mine waste materials throughout the life of mine. Allowance for a water treatment facility has been included to manage site water discharge and ensure compliance with applicable environmental regulations and water quality standards. Figure 08 shows the general site plan.

Initial and Sustaining Capital Cost Estimates

The total LOM Capex for the PEA over the 9-year mine life is broken down into Initial Capital and Sustaining Capital Costs (Table 05).

The initial capital cost covers all upfront infrastructure required for mining (excluding mining fleet), crushing, power line, utilities and infrastructure.

The sustaining capital cost schedule (Figure 09) is primarily driven by underground mine development and sustaining underground infrastructure. Sustaining capital costs for underground mine development in Year 2 enable the Project’s transition from open pit mining to underground production. This represents the capital required to initiate underground access and infrastructure in preparation for underground production anticipated in Year 3. The sustaining capital costs across Years 3 through 9 represent ongoing underground development required to support continued underground production. Sustaining capital costs ensure ongoing mine development required to access production stopes, maintain underground infrastructure, and support long-term operations.

The Capex conforms to Class 5 guidelines established by the Association for the Advancement of Cost Engineering International (AACE International).
