  thenewswire.com
    VANCOUVER, BC – TheNewswire – July 7, 2025 – Viva Gold Corp (TSXV: VAU; OTCQB: VAUCF) (the “Company” or “Viva”)  is pleased to announce the results of its updated Mineral Resource  Estimate (“MRE”) and Preliminary Economic Assessment (“PEA”) for its  100%-owned Tonopah Gold Project (“Tonopah or Project”). Tonopah is  located about 20 minutes’ drive from the town of Tonopah, Nevada. The  study was prepared by WSP Canada Inc. (“WSP”) of Calgary, Alberta and Kappes, Cassiday Associates (“KCA”)  of Reno, Nevada. All amounts shown in this news release are in United  States Dollars and metric units of measurement unless otherwise stated. 
        Tonopah Project PEA & MRE Highlights 
      -   The updated MRE reports  measured and indicated (“M”) Mineral Resource containing 504,000 ounces gold (“Au”) at 0.59 grams per tonne (“g/t” Au, 1.8 million ounces silver (“Ag”) 2.05 g/t Ag, and an inferred Mineral Resource of 83,000 ounces Au at 0.37 g/t Au, 402,000 ounces Ag, at 1.81 g/t Ag, all constrained within a pit shell above a 0.15 g/t Au cut-off (see Table 1).   
    -   Life of mine “LOM”) PEA production of 23.5 million tonnes of Mineral Resource;  consisting of 4.5 million tonnes at an average grade of 1.75 g/t Au and  3.35 g/t Ag as mill circuit feed; and 19.0 million tonnes at 0.37 g/t  Au and 1.69 g/t Ag to the heap leach; at a strip ratio of 3.9 tonnes of  waste per tonne of mineralized material.   
    -   Average mill circuit gold recoveries of 93% Au, 37% Ag, and heap leach Au recoveries of 75% Au, 14% Ag, to produce  a total of 404,000 ounces of payable Au and 354,000 ounces of Ag over a  seven-year mine life with an additional year of residual Au/Ag recovery from the heap leach.  
    -   After-tax net present value (“NPV”) at a 5% discount rate (“NPV5%”) of $111.6 million at a gold price of USD$2,400 per ounce($27.70 Ag increasing to $363.6 million at a gold price of $3,200 per ounce ($36.93 Ag).       
    -   After-tax Internal rate of return (“IRR”) of 17.6% at a  gold price of $2,400 per ounce increasing to an IRR of 43.4% at a gold  price of $3,200.  
    -   After-tax payback period of 3.6 years from commencement of production at $2,400 per ounce Au, decreasing to 1.8 years at an Au price of $3,200 ($36.93 Ag).  
    -   Average production cash costs of $1,164 per ounce of Au and All-In Sustaining Cost (“AISC”) of $1,269 per ounce Au.    
    -   Pre-production capital expenditure of $219.9 million, $22.2 million in working capital,  and additional LOM sustaining capital of $70.4 million including  purchase of mine fleet under capitalized lease/purchase terms. New  equipment pricing is assumed at this phase of work.   
          “This detailed PEA of the Tonopah Gold Project  demonstrates significant leverage to the price of gold and displays  accretive potential value when compared to Viva’s current market  capitalization”, states James Hesketh, President & CEO. “The Tonopah  gold project represents a unique opportunity to develop a gold project  in one of the best mining jurisdictions in the world with excellent  existing infrastructure and proximity to surrounding producers and  metallurgical facilities. This location reduces infrastructure capital  and can help to accelerate the permitting process. Opportunity may exist  to defer or reduce initial capital expense through toll  processing/milling, purchased of used equipment, or through contract  mining with competitive bidding versus owner mining operations. We also  believe that a unique permitting environment exists in the US and Nevada  and Viva intends to accelerate feasibility study on Tonopah which will  allow Viva to initiate the permitting process to take advantage of that  window. In addition, while Viva’s focus is on advancing its core gold  resource through feasibility and permitting, we remain convinced that  substantial exploration potential remains in and around our project  area, which we can demonstrate from existing drill results”.         
        Project Description 
        Viva’s 100% owned Tonopah gold project sits in the middle of gold mining country about a half hour drive south of the Round Mountain mine owned by Kinross Gold  and controls a major land position on the prolific Walker Lane Trend in  Western Nevada. Viva has developed a high confidence level gold Mineral Resource  and can demonstrate the potential for an economically viable open pit,  heap leach/mill gold project through rigorous PEA study. The Project  enjoys paved highway access,  and proximity to Nevada grid power, commercial water supply, and a vast  local vendor network for sourcing required mining project consumables  and equipment.  
        Tonopah is a near surface, well oxidized, epithermal  gold/silver deposit with gold mineralization occurring in higher-grade  veins and brecchias, all  within a blanket of low-grade disseminated gold mineralization. Drill  results demonstrate the potential for additional exploration potential,  while the core Mineral Resource  has been drilled to a high confidence level with approximately 87% of  total contained gold ounces in the M&I resource category. The  Project is located on 508 unpatented federal lode claims.  
        The PEA study was developed using conventional open pit hard rock mining methods at a nominal rate of approximately 45,000 tonnes per day (“TPD”) of  material mined over a seven-year period. Pit slope angles are based on  geotechnical study completed for Viva in 2020. Mined gold mineralization  is transported by truck to either a high-grade (> 1.0 g/t) or low-grade stockpile. Barren waste rock would go to a waste rock storage facility. 
        Process design was developed based on preliminary indicative metallurgical testwork. The process considers crushing 10,000 TPD of mineralized run-of-mine material including 8,000 TPD of low-grade and 2,000 TPD  of high-grade material. Mineralized material will be crushed to 100%  passing 12.5 mm using a three-stage closed crushing circuit. High-grade  and low-grade material will be campaigned through the crushing circuit  and stockpiled separately using a radial stacking conveyor. Low-grade  material will be agglomerated with cement, before being  conveyor-stacked in 10m lifts onto a permanent geomembrane-lined heap  leach pad and leached with a dilute cyanide solution. Pregnant leach  solutions will be pumped to a carbon adsorption circuit. Gold will be  collected onto activated carbon and then periodically transported  off-site to be toll-processed where the loaded carbon will be stripped  and regenerated before being returned to the Project for re-use.   
        High-grade mill feed ground to 80% passing 150 Mesh (106 micron) in a single stage ball mill circuit. Ball mill discharge will be diverted to a Carbon-in-Leach (“CIL”)  circuit where the thickened slurry will be mixed with activated carbon  with a portion of the flow being diverted to a gravity concentrator for  the recovery of coarse metal. Loaded carbon from the CIL will be  toll-processed along with carbon from the heap leach circuit. Leached  slurry will be discharged and filtered using a filter press, and  dry-stacked using trucks onto a dedicated portion of the heap leach pad.    
        The Tonopah open pit will extend below the existing water  table. As a result, a pit de-watering system is required to de-water  ahead of mining advance. A conceptual dewatering system design for the Project was developed by Piteau Associates of Reno, Nevada, Viva’s long term hydrologic consultant, dated June 20, 2025. 
        Existing project infrastructure includes paved State  highway access, nearby 15 KV grid powerline upgradable to 25 KV, newly  constructed cell and data communications tower, and nearby public  utility water supply. The project has a total of 26 existing groundwater  monitoring wells. Additional infrastructure will include fencing and  gates, weigh scale, office buildings, repair shops, assay laboratory,  fencing and gates, water supply system, power substation and overhead  distribution lines.  
       Mineral Resource 
       The 2025 MRE incorporates data from 59 new drill holes  completed since 2022, as well as a new structural model based on  drilling and Controlled Source Audio-frequency Magnetotellurics (CSAMT)  data. The updated resource model has resulted in an increase in the  indicated resource, demonstrating enhanced confidence in the geologic  interpretation.

     |         Notes: 
     -   The MRE for the potentially surface mineable resource  were constrained by conceptual pit shells for the purpose of  establishing reasonable prospects of eventual economic extraction based  on potential mining, metallurgical and processing grade parameters  identified by studies performed to date on the Project.   
    -   Key constraint inputs included reasonable assumptions for  operating costs, geotechnical slope parameters, forecast Au prices, and  a minimum Cut-off Grade of 0.15 g/t Au.  
    -   The Cut-off Grade assumes a gold price of US$2,200 and a  revenue factor of 1.2 (equivalent to US$2,640 gold price), and includes  all material that can be economically processed  
    -   Heap leach recovery of 75% was assumed.  
    -   Tonnage and contained metal estimates are rounded to the nearest 1,000.  
    -   kt = kilotonnes; g/t = grams per tonne; oz/t = troy ounces per tonne.  
    -   Mineral Resource categorization of Measured, Indicated  and Inferred Mineral Resources presented in the summary table is in  accordance with the CIM definition standards (CIMDS, 2014).   
    -   No mining recovery, dilution or other similar mining parameters have been applied.   
    -   Although the Mineral Resources presented in this press  release are believed to have a reasonable expectation of being extracted  economically, they are not Mineral Reserves. Estimation of Mineral  Reserves requires the application of modifying factors and a minimum of a  PFS.   
    -   The reported Inferred Mineral Resources are considered  too speculative geologically to have the economic considerations applied  to them that would enable them to be categorized as Mineral Reserves.   
    -   There is no certainty that all or any part of this Mineral Resource will be converted into Mineral Reserve.  
    -   Mineral Resource estimates are not precise calculations,  being dependent on the interpretation of limited information on the  location, shape and continuity of the occurrence and on the available  sampling results. All figures are rounded to reflect the relative  accuracy of the estimates.   
          The Mineral Resource categorization applied by the  Qualified Person (“QP”) has included the consideration of data  reliability, spatial distribution and abundance of data and continuity  of geology and grade parameters. The QP performed a statistical and  geostatistical analysis for evaluating the confidence of continuity of  the geological units and grade parameters. The results of this analysis  were applied to developing the Mineral Resource categorization criteria. 
        The updated MRE reports 504,000 ounces of measured and  indicated gold resources at 0.59 g/t Au, constrained within a pit shell  above a 0.15 g/t Au cut-off (see Table 1). Compared to the 2022 PEA,  this is an increase of 109,000 ounces of measured and indicated Mineral Resources, and a reduction of 123,000 ounces of inferred Mineral Resources.  Additional drilling reduced drill hole spacing and revealed new  high-grade zones as well as non-mineralized areas. The introduction of a  structural interpretation served to constrain the estimate to  additional hard-boundary domains. For the first time, 2,164,000 ounces  of silver at 2.0 g/t are reported.  
        Au and Ag  were estimated into a 3D block model using ordinary kriging  interpolation. The block size in the area of the reported resources is 6  m x 6 m x 6 m. Estimation was constrained by hard boundary domains  based on rock type and fault boundaries.  
        Primary differences between the 2022 resource block model  and the 2025 resource block model include a reduction in block size  from 20 m to 6 m, a change in the Au top-cut grade parameters (increased  from 10 g/t to 100 g/t and using a high-grade search restriction), and a  change to the resource classification methodology. 
           At present, only Mineral Resources have been estimated and there are no Mineral Reserves for the Project.  
       The Mineral Resource estimates for the potentially  surface mineable resources at Tonopah were constrained by conceptual  resource pit shells for the purpose of establishing reasonable prospects  of eventual economic extraction based on potential mining,  metallurgical recovery and processing parameters identified by mining,  metallurgical, and processing studies performed to date on the Project. 
        Key constraint inputs included reasonable assumptions for  operating costs, geotechnical slope parameters, Au forecast prices, as  summarized in Table 2, resulting in a minimum Cut-off Grade (“COG”) of 0.15 g/t Au. The COG assumes a gold price of US$2,200 and a revenue factor (“RF”) of 1.2 (equivalent to US$2,640 gold price) and includes all material that can be economically processed.

     -   The mineral and waste mining cost were based on escalated  mining cost from similar projects in Nevada and nearby states escalated  to Q2 2025 US$ value. The overburden mining cost is the cost of free  digging the overburden, without drilling and blasting.  
    -   Mining sustaining capital cost of 0.24 $/t was calculated  based on the escalated April 2020 PEA cost estimate to Q2 2025 US$  value and was included in the pit optimization to the mining cost.  
    -   The block model described included dilution or mining  recovery. Viva recommended to use 100% mining recovery and 0% dilution,  and it is the QP’s opinion that this logic is reasonable for a PEA-level  study.  
    -   Mill processing sustaining capital cost of 0.11 $/t was  obtained from the April 2020 PEA cost estimate and escalated to Q2 2025  US$ value.  
    -   Heap leach processing sustaining capital cost of 0.62 $/t  was obtained from industry benchmarking, and both were included in the  pit optimization to the processing cost for all scenarios.  
          PEA Mine Plan and Production Details 
       Tonopah will have a seven-year mine life with eight years  of gold recovery. Closure and reclamation activities are expected to  commence at the cessation of mining and last for a period of three years  utilizing exiting mine equipment and personnel. Please  note that a Preliminary Economic Assessment is preliminary in nature  and includes inferred mineral resources that are considered too  speculative geologically to have the economic consideration applied to  them that would enable them to be categorized as mineral reserves, and  that there is no certainty that the preliminary economic assessment will  be realized.

       PEA Study Economic Analysis 
        The PEA economic analysis is based on the estimated  production schedule, capital costs, and operating costs, and cash flow  model prepared by WSP. All information used in this economic evaluation  was derived from work completed by WSP and KCA, with support from Viva  Gold.  
       Project economics were evaluated using a discounted cash  flow method that measures the before-tax and after-tax NPV of future  cash flow streams. The PEA economic model was based on the following key  assumptions: 
     -   A gold price of $2,400 per ounce.  
    -   Mine production schedule developed by WSP with a nominal average mining rate of 45,000 TPD with higher levels in the first two years and a mill and heap leach process rate totaling 10,000 TPD of mineralized material.   
    -   A period of analysis of eleven years that includes one year of investment,  years of production, and three years to complete reclamation and closure commencing after cessation of mining activities.   
    -   Capital costs as summarized in Table 9 and operating costs as summarized in Table 7 and described in the following sections.   
          Project economics are based on criteria from the cash flow model that are summarized in Table 5.

     |     $4,740 
     |          Process and infrastructure capital can be divided into  two components: preproduction capital for crushing, leaching systems,  and infrastructure with a total preproduction capital cost of  approximately $119.5 million including all contingencies and EPCM; and  mill circuit costs of $52.5 million all inclusive  
        All process and infrastructure equipment and material  requirements are based on the design information as determined by KCA.  Capital cost estimates were developed based on budgetary project  specific quotes or recent quotes from  similar projects in KCA’s files for all major and most minor equipment.  Where recent quotes were not available, reasonable cost estimates or  allowances were made based on cost guide data. All  capital cost estimates were based on the purchase of equipment quoted  new from the manufacturer or to be fabricated new. Capital cost  estimates were based on the second quarter of 2025 US dollars and are  considered to have an accuracy of +/-35%.   
        Mine equipment cost is based primarily on a Financing  Proposal received from Caterpillar Financial Services Corporation data  June 18, 2025. The fleet consists of eleven-100 tonne CAT 777 haul trucks with three CAT  992 loaders, three CAT MD6250 drills and associated auxiliary  equipment. Terms include a 20% down payment and the equipment is leased  over a three-year period in equal payments of principal and interest.  Equipment is purchased with a $1.00 purchase option at the end of the  lease. Mine infrastructure, indirect and contingency costs were based on  similar projects in WSP’s files and reasonable cost estimates or  allowances were made based on cost guide data.   
        Dewatering capital was estimated to account for the drilling of interceptor wells in surface gravel’s  and basement rock, and the construction of HDPE pipeline to convey  water directly to valley floor re-infiltration basins where clean water  is discharged directly back into valley floor gravels. Royalty cost  reflects the cost required to exercise the option to acquire 1% of the  Tonopah 2% net smelter return royalty.   
         Project Closure and Environmental Closure Bonding 
        Federal and State agencies require a reclamation bond to  ensure completion of reclamation and closure of Tonopah, estimated at  $23.7 MM, if performed by the State. Actual closure costs if performed  using existing mining equipment and personnel are estimated at $12.0  million. Viva anticipates using a Surety policy to cover bond costs  which would include providing 20% cash collateral into an  interest-bearing restricted cash account and paying an annual surety  premium estimated to be $380,000, which is included in G&A costs.  
        Mine Permitting 
        Permits required for the proposed surface mining  operation will include, but not be limited to, Bureau of Land Management  Mine Plan of Operation/National Environmental Policy Act analysis,  Environmental Impact Statement, Amended Nevada Mining Reclamation  Permit, Nevada Water Pollution Control Permits, Air Quality Operating  Permit, Liquified Propane Gas license, Nevada water rights, and Nevada  Industrial Artificial Pond permit. 
        Recommended Forward Studies 
        WSP makes the following recommendations:  
     -   A diamond drill core program to capture additional data  such as specific gravity measurements, core recovery, rock quality  designation RQD),  and the location and angles of major faults to further refine tonnage  estimates for the project and existing structural interpretations.   
    -   Developing an alteration model could improve  understanding of its impact on gold mineralization and potentially  identify new drill targets.  
    -   A more detailed tradeoff study between leasing production  equipment vs. purchasing should be undertaken (perhaps even a hybrid of  the two options) to assess if up-front capital can be reduced and  evaluate the effects on operating costs.  
       -   More detailed phasing of the open pit at a PFS level  should be undertaken given the nature of the grade and strip ratio of  the deposit to help focus on bringing more high-grade material up front  to help offset the initial capital cost payback.  
          KCA has made recommendations for additional metallurgical studies including:  
     -   High-grade mill and gravity variability testing  
    -   Variability column testing at various crush sizes (9.5mm, 12.5 mm, 25 mm and 38mm) for a 120 to 180-day period.   
    -   Perform additional characterization work.   
          Samples for KCA’s metallurgical  program may be captured in the diamond core program recommended by WSP.  The cost of a 1,000 meters PQ drill program including assay, teleview/oriented  core study is approximately $500,000 not including additional cost for  specific gravity testing. Quotations for metallurgical testwork and updated geotechnical study are in process.    
        Environmental study recommended by Lewis Consulting LLC, Viva’s long term environmental consultant, includes:  
     -   Ongoing baseline study work for environmental monitoring, cultural  resources surveys, biological studies, and hydrogeologic studies.   
    -   Construction of one upgradient and two downgradient groundwater monitoring wells.   
    -   Thirty-day aquifer tests from the existing site bedrock and alluvial  production/monitoring wells, should be conducted to support the  numerical groundwater model required for Federal and State permitting.   
    -   A program to test the capacity of alluvial soils to allow infiltration of excess mine dewatering water.   
    -   A Class III cultural resources survey should be completed for those  areas within the projected Project boundary that have not been surveyed  in more than ten years.   
    -   Two years of Golden Eagle and Raptor aerial surveys should be completed  to develop plans and permits if necessary to ensure compliance with the  Bald and Golden Eagle Protection Act.   
          It is anticipated that these recommended environmental study activities will cost approximately $900,000.

          Cautionary Note to Investors ---  Investors are cautioned not to assume that any "measured mineral  resources", "indicated mineral resources", or "inferred mineral  resources" that the Company reports in this news release are or will be  economically or legally mineable. United States investors are cautioned  that while the SEC now recognizes "measured mineral resources",  "indicated mineral resources" and "inferred mineral resources",  investors should not assume that any part or all of the mineral deposits  in these categories will ever be converted into a higher category of  mineral resources or into mineral reserves.  These terms have a great  amount of uncertainty as to their economic and legal feasibility.  Under  Canadian regulations, estimates of inferred mineral resources may not  form the basis of feasibility or pre-feasibility studies, except in  limited circumstances.  Further, "inferred mineral resources" have a  great amount of uncertainty as to their existence and as to their  economic and legal feasibility.  It cannot be assumed that any part or  all of an inferred mineral resource will ever be upgraded to a higher  category. The mineral reserve and mineral resource data set out in this  news release are estimates, and no assurance can be given that the  anticipated tonnages and grades will be achieved or that the indicated  level of recovery will be realized.  
        Neither TSX Venture Exchange nor its Regulation Services  Provider (as that term is defined in the policies of the TSX Venture  Exchange) accepts responsibility for the adequacy or accuracy of this  release. 
        Definitions 
        “All-in sustaining costs” is a non-IFRS or US GAAP  financial measure calculated based on guidance published by the World  Gold Council (“WGC”). The WGC is a market development organization for  the gold industry and is an association whose membership comprises  leading gold mining companies. Although the WGC is not a mining industry  regulatory organization, it worked closely with its member companies to  develop these metrics. Adoption of the all-in sustaining cost metric is  voluntary and not necessarily standard, and therefore, this measure  presented by the Company may not be comparable to similar measures  presented by other issuers. The Company believes that the all-in  sustaining cost measure complements existing measures and ratios  reported by the Company. All-in sustaining cost includes both operating  and capital costs required to sustain gold production on an ongoing  basis. Sustaining operating costs represent expenditures expected to be  incurred at the Project that are considered necessary to maintain  production. Sustaining capital represents expected capital expenditures  comprising mine development costs, including capitalized waste, and  ongoing replacement of mine equipment and other capital facilities, and  does not include expected capital expenditures for major growth projects  or enhancement capital for significant infrastructure improvements. 
       “Cash cost per gold ounce” is a common financial  performance measure in the gold mining industry but has no standard  meaning under IFRS or US GAAP. The Company believes that, in addition to  conventional measures prepared in accordance with IFRS or US GAAP,  certain investors use this information to evaluate the Company’s  performance and ability to generate cash flow. Cash cost figures are  calculated in accordance with a standard developed by The Gold  Institute. The Gold Institute ceased operations in 2002, but the  standard is considered the accepted standard of reporting cash cost of  production in North America. Adoption of the  standard is voluntary, and the cost measures presented may not be  comparable to other similarly titled measures of other companies.  |
