 Toronto, Ontario--(Newsfile Corp. - October 21, 2025) - XXIX Metal Corp?. (TSXV: XXIX) (OTCQB: QCCUF) (FSE: 5LW0) ("XXIX" or the "Company") is pleased to announce the completion of a Preliminary Economic Analysis ("PEA")[1] on its Opemiska copper project ("Opemiska"),  located in Chapais, Québec. The PEA evaluates the potential economic  viability of Opemiska's mineral resources and is the first economic  study on Opemiska since Falconbridge closed its underground mining  operations in 1991.Plenty of Resource upside including Cooke gold zone with active drilling underway.
 
 "This is a significant milestone for Opemiska  and XXIX. The results clearly indicate Opemiska's potential as a  profitable operation Furthermore, the high-grade early years of the mine  has resulted in a low C1 cash cost of US$1.03/lb (net of by-product  credits) over the first six years, and US$1.40/lb (net of by-product  credits) over the 17-year life of mine, placing the project in the lower  quartile of the cost curve,"  said Guy Le Bel, CEO of XXIX.  "This  project has the potential to bring in significant benefits to all  stakeholders involved, including the town of Chapais and surrounding  communities."
 
 Project Overview
 
 The 100%-owned  Opemiska spans 21,333 hectares in Quebec's Chapais-Chibougamau region,  with significant infrastructure in place. Opemiska comprises four  past-producing mines, two of which (Springer and Perry) underpin the  current PEA. Cooke, a third past-producing mine located ~3km east of the  proposed pit is currently being evaluated for its gold resource  potential.
 
 Figure 1)  Location of the Opemiska Project
 
 The  PEA envisions an open pit mining and milling operation with a  processing capacity of 12,500 tonnes per day, over a 17-year life of  mine ("LOM"). The project has been optimized by sequencing the open pit  mining extraction schedule in four distinct phases and by segregating  mineralized material to process higher value material upfront. The  optimized processing schedule demonstrates an average annual production  of 62 million lbs of copper, 38 thousand ounces of gold and 193 thousand  ounces of silver over the first six years of production and 44 million  lbs of copper, 27 thousand ounces of gold and 130 thousand ounces of  silver over the entire LOM.
 
 Table 1 presents a summary of  operating and financial highlights from the PEA, using Base Case and  Spot Pricing assumptions. A foreign exchange of C$1.35 to US$1.00 has  been used for this economic analysis.

 Mineral Resources
 
 Opemiska's  production profile is contemplated as a 55% subset of the pit  constrained indicated and inferred mineral resource estimate ("MRE") previously announced on  June 3, 2025.  As such, the PEA is preliminary in nature and 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 PEA  will be realized. Figure 2 compares the MRE resource constraining pit to  the open pit envisioned in the PEA.
 
 Figure 2)  MRE Constraining Pit Shell vs. PEA Pit Shell
 
 Mining - A Phased Approach
 
 The  PEA contemplates a conventional open pit truck-and-shovel operation  with a 12,500 tpd (4.6 Mtpa) processing rate over 17-year LOM, with an  average strip ratio of 3.7 to 1. The mine plan has been optimized across  four phases for a rapid payback on initial capital supported by strong  annual cash flow. The four mining phases are detailed as follows:  starter pits in both Springer and Perry (Phase 1), an intermediate  pushback in Springer (Phase 2), the depletion of Perry (Phase 3), and  the depletion of Springer (Phase 4). The 17-year LOM incorporates 13  years of direct mill feed from open pit operations and 4 years of  stockpile rehandling. The open pit operation has also been optimized to  delay any impact to the neighbouring town of Chapais to the end of Phase  3 and beginning of Phase 4. Figure 3 outlines the 13-year mine  production schedule.  Figure 4 - 7 shows the pit outline for each the  four phases.

 Figure 7)  Phase 4 - Springer Depletion
 
 Processing & Metallurgy
 
 The  PEA envisions a typical flotation metallurgical flowsheet for the  recovery of a copper concentrate with gold and silver, that is amenable  to smelting. The flowsheet (Figure 8) incorporates 2 stage crushing,  SAG/ball mill grinding, rougher flotation, concentrate regrind and  cleaner flotation followed by concentrate thickening and filtration,  resulting in a final concentrate with a copper grade of 20%. The  tailings are thickened, filtered and trucked to the co-disposal facility  where encapsulation with waste rock will be promoted.
 
 The  process plant will treat 4.6 Mt/y of mineralized material, at an average  throughput of 12,500 t/d. The grinding and flotation design  availability is 8,059 hours per year or 92%. The crushing design  availability is 5,694 hours per year or 65%. The tailings and  concentrate filtration design availability is 7,183 hours per year or  84%. Average life-of-mine recoveries, based on testwork, and supported  by historical operations data[3], are estimated to be 92% for  copper, 80% for gold and silver. Figure 9 outlines mill production  schedule across the 17-year LOM.
 
 Figure 8) Process Flow Sheet
 
 Metallurgical  testing was completed on a composite sample at SGS (Quebec City) in  2023. The composite was made up of core, sourced from intervals weighted  proportionally to the deposit mineralized domains and intersecting all  lithologies. The purpose of this testwork was to evaluate the  metallurgical performance and environmental properties of mineralized  material from the Opemiska deposit through conventional flotation  processes and provide material inputs to inform the PEA design.  The  testwork results indicated copper recoveries to concentrate of  approximately 92%.

 Capital & Operating Costs
 
 Initial capital is estimated at C$617M over a 2-year construction period, and is based on the costs outlined in Table 3, below:
 
 Table 3) Breakdown of Initial Capital
 
 
 | Initial Capital Expenditure | Cost (C$M)
 |  | Infrastructure | 16.2 |  | Electricity and Communications | 27.0 |  | Tailings Management | 14.5 |  | Water Management | 6.9 |  | Mining Equipment | 45.6 |  | Process Plant | 271.0 |  | Indirects | 106.2 |  | Contingency | 121.4 |  | Capitalized Operating Costs | 8.4 |  | Initial Capital | 617.3 |  | Clean Technology Manufacturing Investment Tax Credit (CTM-ITC) | (149.6) |  | Initial Capital (net of Clean Technology Manufacturing Investment Tax Credit) | 467.7 | 
 
 The  Company may be eligible to receive the Clean Technology Manufacturing  Investment Tax Credit (CTM-ITC).  This legislation has been enacted on  June 20, 2024. XXIX expects to receive ~$149.6M in CTM-ITC as 100% of  revenue for Opemiska is generated from sale of copper concentrate,  copper being one of six qualifying materials. There is no guarantee the  Company will be able to access the CTM-ITC. If the CTM-ITC does not  become available, the total capital cost including contingency will  increase by the amounts shown in this row.
 
 Sustaining capital over the LOM is estimated at $390.9M, while closure costs are estimated at $40.0M.
 
 Operating  costs are estimated at C$34.52/tonne processed, based on the costs  outlined in Table 4, below. Costs pertaining to transportation,  placement and compaction of the tailings have been included as part of  the mining cost.
 
 Table 4) LOM Unit Operating Costs
 
 
 | Unit Cost | Unit | Cost |  | Mining | C$/t mined | 4.39 |  | Mining | C$/t processed | 20.66 |  | Processing | C$/t processed | 10.62 |  | Waste and water management | C$/t processed | 0.08 |  | G&A | C$/t processed | 3.16 |  | Total | C$/t processed | 34.52 | 
 
 C1  Cash costs over the LOM are estimated at US$1.40/lb Cu (net of  by-product credits), with C1 cash cost during Years 1 - 6 being  US$1.03/lb Cu. A breakdown of C1 cash cost is outlined in Table 5,  below:
 
 Table 5) C1 Cash Cost Breakdown (Base Case)
 
 
 | C1 Cash Cost (US$/lb) | Year 1 - 6 | LOM |  | Mining | 1.61 | 1.65 |  | Processing | 0.59 | 0.85 |  | Waste and Water Management | 0.01 | 0.01 |  | G&A | 0.18 | 0.25 |  | Transportation and Logistics | 0.30 | 0.30 |  | TCs / RCs | 0.14 | 0.14 |  | Gold by-product credit | -1.70 | -1.72 |  | Silver by-product credit | -0.09 | -0.08 |  | Total C1 Cash Cost | 1.03 | 1.40 | 
 
 Economic Analysis Results
 
 The  PEA highlights Base Case NPV8% of C$505M with a corresponding IRR of  27.2% and a 2.3-year payback period. Under Spot Pricing, NPV8% increases  to C$897M, with a corresponding IRR of 39.3% and a 1.8-year payback.   Assumptions, including commodity pricing and exchange rate used as part  of the economic analysis is outlined in Table 6, below:
 
 Table 6) Commodity Price & Exchange Rate Assumptions
 
 
 | Assumption | Base Case | Spot Pricing |  | Copper price (US$/lb) | 4.35 | 4.75 |  | Gold price (US$/oz) | 3,000 | 4,300 |  | Silver price (US$/oz) | 30 | 54 |  | CAD : USD | 1.35 | 1.38 | 
 
 Opemiska On-site Infrastructure
 
 Opemiska's  site layout comprises the processing plant, power infrastructure,  tailings management facility and administrative buildings. Figure 10  outlines Opemiska's envisioned site layout.
 
 Figure 10) Opemiska Site Layout
 
 Tailings Management
 
 XXIX  will utilize filtered tailings management, providing multiple  advantages over conventional tailings management strategies.  Filtered  tailings management does not utilize tailings ponds, mitigating  stakeholder risk exposure to catastrophic failure and flooding and/or  uncontrolled leaks or seepage.
 
 Filtered tailings management sees  tailings treated through filters prior to being deposited in layers,  stacked and compacted on specially designed platform lined with a  geomembrane.  As part of the filtration process, water is removed from  the mixture resulting in drier material-similar to soil such as a fine   sand. Using such technology and tailings management strategy assists in  streamlining progressive  reclamation activities.
 
 Opportunities
 
 Evaluate  ore sorting as a mechanism to further improve processing head grades of  lower grade stockpiled material.  Mineral sorting can also lead to  optimized costs by rejecting waste material earlier in the process,  potentially increasing overall economics.
 
 Evaluate potential  mineralized material at the bottom of the envisioned pit as well as  mineralized material outside of the envisioned pit to further boost  project economics.
 
 Future testwork programs will investigate the  potential to further improve concentrate grades, which would reduce  concentrate mass to be transported and improve payability. Mineralogical  analysis also revealed the potential to recover coarse gold via gravity  concentration; future testwork will be conducted to confirm.
 
 Testwork  to be performed on filtered tailings will investigate their compaction  potential which could allow reducing the overall height and footprint of  the co-disposal facility.
 
 Next Steps and Upcoming Catalysts
 
 Exploration of Cooke Gold Zone - Q4 2025 / Q1 2026
 
 A  6,000-metre drill program has commenced at Cooke to determine potential  for a near surface resource that could complement Opemiska's existing  resource base. Cooke was a past producing underground mine with two  parallel gold structures that have not been mined to surface.  Historically, Cooke produced 1.97 million tonnes grading 5.04 g/t gold  and 0.66% Copper[4]. Cooke has up to 200 metres of crown pillar intact, increasing potential for high-grade near surface gold mineralization.
 
 Prefeasibility Study - 2026 - onwards
 
 XXIX  will continue to progress Opemiska towards a Pre-Feasibility Study  ("PFS").  As such, the company will have to complete additional studies  including:
 
 
 Outstanding Risk FactorsEnvironmental  Baseline Studies:  XXIX will commence environmental baseline studies in  2026 to assess potential impacts of Opemiska and potential future mining  operations.  Environmental baseline studies are critical paths of the  mine permitting process, ensuring that companies are complying with the  applicable environmental regulation and current practice  recommendations.
 
Metallurgical Studies: The company will  pursue metallurgical testing to confirm/optimize the flowsheet design,  characterize the tailings for filtration and acid generation potential,  characterize waste for acid generation/neutralization potential and  evaluate ore sorting for the low grade material.
 
Geotechnical  Studies:  The purpose of these studies is to confirm assumptions on  slope angles in the pit, and the stability of the co-disposition  facility.
 
Stakeholder Engagement:  XXIX commits to  constant transparent dialogue with the communities where we operate. In  2026, we will organize a number of meetings to discuss how the proposed  project can be bonified to the benefits of the citizens.
 
3D Geological Model Upgrade: The Opemiska 3D geological model will be upgraded prior to commencing the PFS.
 
 
 The  XXIX technical team has identified several key risks that could impact  the development of the Opemiska Project. These are being carefully  evaluated and will be addressed in future engineering and economic  studies:
 
 
 a)      Open stopes in the eastern pit wallProximity to  the Town of Chapais: The conceptual pit in the current PEA partially  overlaps with the town boundary. This could raise social acceptance  issues and may require trade-off studies or additional capital for  development solutions.
 
Historical Assay Validation: Drill  core from mining operations between 1953 and 1991 no longer exists,  meaning historical mine assays cannot be directly verified. While  limited twin-hole drilling supports their general reliability, a  geostatistical validation study was done during the process of the 2025  MRE and the QP was able to validate historical assays using information  coming from valid and QAQC-proof recent holes. Additional detailed  validation programs will be needed as the project advances.
 
Geotechnical Considerations: Known geotechnical challenges include:
 
 Rock:
 
 b)      The Venture Sill, which dips toward the pit wall and may affect slope stability
 c)      The Gwillim Fault, which may pose a water inflow risk if it hosts an aquifer
 Despite these concerns, the host rock is generally strong and well-suited to open-pit mining.
 d)      The host rock competency is confirmed, in part, by the stability of the glory hole sidewalls over the past 40 years.
 
 
 a)      The feasibility of tailings filtration has not yet been demonstrated.Tailings and foundation soils:
 b)      The geotechnical properties, characteristics, and behavior of filtered tailings have not yet been established.
 c)      The geotechnical properties, characteristics, and behavior of the foundation soils have not yet been established.
 
 
 ?About XXIX Metal Corp?.Geochemical, Hydrogeological and Water Treatment and Management Consideration 
 
 The  mine waste environment has not yet been studied for environmental  characteristics to confirm its potential for acid generation and metal  leaching.
 
The hydrogeological context is unknown and requires further study to assess the potential impacts of mining activities.
 
The  effects of mining activities on water quality (both groundwater and  surface water) have not yet been evaluated, and the need for water  treatment should be assessed.
 
Comprehensive water balance yet to be completed
 
Historical  Stope Modeling: Digitized historical stopes from the Springer and Perry  mines may not perfectly align with the current 3D models. Some  mined-out areas may not fully match up with mineralized zones,  introducing potential grade uncertainty. The Company considers this  manageable for now but will re-digitize certain areas as development  progresses.
 
The sale terms for the concentrate are  indicative and based on historical terms. The LOM concentrate offtake  has not yet been negotiated.
 
 
 XXIX  is advancing its Opemiska and Thierry Copper projects, two significant  Canadian copper assets. The Opemiska Project, one of Canada's  highest-grade open pitable copper deposits, spans 21,333 hectares in  Quebec's Chapais-Chibougamau region, with strong infrastructure and  nearby access to the Horne Smelter. An October 2025 Preliminary Economic  Assessment outlined a 12,500 tpd open pit operation over a 17-year mine  life, generating an after-tax NPV8% of $505M, IRR of 27.2%, and a  2.3-year payback period ($4.35/lb copper price, $3,000/oz gold price,  $30/oz silver price).  The Thierry Project hosts the K1 (near-surface)  and the past-producing K2 (underground & surface) zones (see XXIX  news release dated October 1, 2024 for details regarding resources).  Thierry has significant infrastructure in place including an all-season  road, an airport within 5km, a provincial power grid within 8km, and  nearby rail. With these two high-potential projects, the Company has  solidified its position as a key player in the Canadian copper sector  and has established itself as one of Eastern Canada's largest copper  developer.
