Vizsla Copper Announces Staking of the Miller Copper-Gold Project, Central British Columbia

Download PDF

Vancouver, British Columbia, September 23, 2026 – Vizsla Copper Corp. (TSXV: VCU, OTCQB: VCUFF, FRANKFURT: 97E1) (“Vizsla Copper” or the “Company”) is pleased to announce the acquisition, through staking, of the highly-prospective Miller copper-gold porphyry project (or “Miller”) in central British Columbia. The road-accessible project is contiguous with Centerra Gold’s Mount Milligan mine and represents an exciting new, cost-effective exploration opportunity in a prospective region close to significant infrastructure.

HIGHLIGHTS

  • Cost-effective Acquisition: The Miller project was acquired through staking and is 100% owned and free of royalties.
  • Strategically Located: The 25,274-hectare Miller project borders Centerra Gold’s producing Mount Milligan mine and covers numerous priority copper-gold exploration targets near existing infrastructure.
  • Acquisition Rationale: The Miller project represents an internally generated copper-gold porphyry project that fits well into the company’s pipeline of exploration projects in British Columbia and Alaska.
  • Generative Work Planned: An airborne mobile magnetotelluric (“MobileMT”) survey is set to commence across the entire Miller project in the coming weeks. The goal of the survey is to investigate the scale of alteration zones of known targets as well as identify new target areas.
  • Fully Funded for 2026; Focus Remains on Core Projects: Vizsla Copper remains focused on the development and exploration of its core assets in Alaska and British Columbia, where it is fully funded to complete all planned activities through 2026 with approximately C$15 million in treasury.

“Miller builds upon our strong copper-led portfolio in Alaska and B.C. and supports our long-term objective of progressing our more advanced projects while continuing to build upon our pipeline of discovery-focused assets, providing multiple pathways for value creation,” commented Craig Parry, Chair and CEO. “We see a significant opportunity to capitalize on the growing copper demand and increasing need for responsibly produced supply from stable North American jurisdictions. With approximately C$15 million in cash, our 2026 field programs are fully funded, positioning us well to advance our portfolio while continuing to pursue new opportunities. We look forward to a steady flow of assay results from our ongoing drill programs at our Palmer VMS project in Alaska and Poplar porphyry project in B.C., where we are following up on a new discovery, as well as remaining results from our recently completed drill program at the Woodjam porphyry project in B.C.”

“We jumped at the opportunity to stake this sizeable land position near significant infrastructure that supports Centerra’s Mount Milligan mine,” commented Steve Blower, Senior Vice President, Exploration. “Regional geological and geophysical datasets suggest the geology at Miller may be similar to that at Mt. Milligan, and I’d like to thank our exploration team for generating this compelling exploration opportunity. Importantly, the mine’s main transmission line and access road traverses across the eastern block of Miller proximal to our highest priority targets. We look forward to the results of the MobileMT survey and subsequent generative exploration activities, such as prospecting and soil geochemistry, in 2027.”

Strategically Located Miller Copper-Gold Porphyry Project

The road accessible, 25,274-hectare Miller project, located approximately 145 kilometers north of Prince George in central British Columbia, consists of two blocks (West and East) that are contiguous with Centerra Gold’s Mount Milligan project (470 Mt at 0.28 g/t Au and 0.17% Cu, Proven and Probable Mineral Reserve, Figure 1)1. Mineral tenures were acquired by staking through Mineral Titles Online and issued under the new British Columbia Mineral Claims Consultation Framework.

The project is underlain by prospective mafic volcanic rocks of the Takla Group and intruded by Jurassic Age composite intrusions, locally associated with porphyry-related Cu-Au mineralization. Both blocks are predominantly covered by glacial till and therefore underlying geology is mostly inferred from regional magnetics. The geophysical data highlights a strong association of prospective intrusions/stocks, similar to what has been observed at Mt. Milligan2, with magnetic-high anomalies. Both blocks contain multiple discreet magnetic high anomalies interpreted to represent concealed and prospective monzonite intrusions.

The eastern block of the Miller project contains three defined target areas, Fred, RPF and Lake (Figure 1). The Fred target consists of locally exposed porphyry-related alteration and Cu-Au mineralization exposed along road-cuts with rock samples up to 0.41 g/t Au and 0.10% Cu3. Mineralization is reportedly locally observed across a 3.5 kilometer NW-SE trend that lacks soil geochemical coverage or IP geophysics and has never been drill tested. The RPF geophysical target comprises a discreet magnetic-high with a coincident open-ended chargeability-high anomaly defined across two lines, which were completed by Teck in 19914. This target also remains untested by drilling. The Lake target, which is located approximately 10 kilometers east of the Mount Milligan Mine, consists of a series of discrete and clustered magnetic-high anomalies. The WM targets on the western block (Figure 1) consist of numerous discreet magnetic-high anomalies, which are interpreted to represent concealed intrusions.

Next Steps

A project-wide airborne mobile magnetotelluric (MobileMT) survey across the entire Miller project area is set to commence in the coming weeks. The survey will consist of 1,667-line kilometers on 200 meter spaced, northeast-southwest oriented lines. The objective of the survey is to image subsurface resistivity and conductivity, to a depth up to 2 kilometers, while investigating the scale of locally concealed alteration zones. These target areas will be further investigated and refined in 2027 with soil and rock geochemical surveys.

WOODJAM PROJECT

Notes on Woodjam Historical Estimates

The Woodjam estimates are historical estimates within the meaning of National Instrument 43-101 – Standards of Disclosure for Mineral Projects. The historical estimates are not being treated by Vizsla Copper as current mineral resources or mineral reserves. A Qualified Person has not done sufficient work to classify the historical estimates as current mineral resources or mineral reserves. Mineral resources are not mineral reserves and do not have demonstrated economic viability.

The historical estimates relate to the Southeast, Deerhorn and Takom deposits and were prepared for Gold Fields Horsefly Exploration Corp. and Consolidated Woodjam Copper Corp. with an effective date of May 15, 2013.

The Southeast historical estimate was disclosed in the technical report titled NI 43-101 Technical Report for 2012 Activities on the Woodjam South Property, Cariboo Mining Division, British Columbia, prepared by Ross Sherlock, Ph.D., P.Geo., Gold Fields Canada Exploration BV, and Alex Trueman, P.Geo., MAusIMM CP(Geo), Gold Fields Exploration, Inc., with an effective date of May 15, 2013. The Southeast historical estimate was completed by Alex Trueman, P.Geo., MAusIMM CP(Geo), Chief Resource Geologist, Gold Fields Exploration Inc.

The Deerhorn and Takom historical estimates were disclosed in the technical report titled NI 43-101 Technical Report for 2012 Activities on the Woodjam North Property, Cariboo Mining Division, British Columbia, prepared by Ross Sherlock, Ph.D., P.Geo., Gold Fields Canada Exploration BV, Jacqueline Blackwell, Ph.D., P.Geo., Gold Fields Canada Exploration BV, and Twila Skinner, P.Geo., Gold Fields Canada Exploration BV, with an effective date of May 15, 2013. The Deerhorn and Takom historical estimates were completed by Brian Wolfe, MAIG, Principal Resource Geologist, Gold Fields Australasia Pty. Ltd.

The Southeast and Deerhorn historical estimates were prepared using localized multivariate uniform conditioning, and the Takom historical estimate was prepared using ordinary kriging. Each historical estimate used a cut-off grade of US$8.60/t. The NSR calculation used metal price assumptions of US$1,650/oz Au and US$3.90/lb Cu and recovery assumptions of 69% Au and 85% Cu. The historical estimates were reported within modelled open pit shells based on price assumptions of US$1,650/oz Au and US$3.90/lb Cu.

Vizsla Copper considers the historical estimates relevant because they provide information regarding mineralization identified at the Woodjam Project and assist in guiding exploration planning. Vizsla Copper considers the historical estimates reliable for these limited purposes because they were prepared by qualified professionals using drilling and sampling information collected using modern methods available at the time. However, Vizsla Copper has not independently verified the historical estimates and readers should not rely on them as current mineral resources or mineral reserves.

Additional work required to verify or upgrade the historical estimates as current mineral resources may include, as applicable, data compilation, confirmation drilling, resampling, data verification, verification of historical drill hole locations and survey data, review and validation of historical QA/QC data, density verification, updated geological modelling, a site visit by a Qualified Person and preparation of a current mineral resource estimate and technical report in accordance with NI 43-101.

A Qualified Person has not done sufficient work to classify the historical estimates as current mineral resources or mineral reserves, and Vizsla Copper is not treating the historical estimates as current mineral resources or mineral reserves. There can be no assurance that the historical estimates, in whole or in part, will ever be verified as current mineral resources or converted into mineral reserves.

POPLAR PROJECT

Notes on Poplar Historical Estimate

The Poplar estimate is a historical estimate within the meaning of National Instrument 43-101 – Standards of Disclosure for Mineral Projects. The historical estimate is based on the technical report titled Technical Report 2021 Update on the Poplar Deposit, Omineca Mining Division, British Columbia, prepared for Universal Copper Ltd. by James Ashton, P.E., SME-RM and Warren Robb, P.Geo., with a report date of September 2, 2021 and filed under Universal Copper Ltd.’s profile on SEDAR on September 8, 2021.

The historical estimate was reported at a 0.20% Cu cut-off within a modelled mineralized solid. The historical estimate comprises 152.3 million tonnes grading 0.32% Cu, 0.009% Mo, 0.09 g/t Au and 2.58 g/t Ag in the indicated category, and 139.3 million tonnes grading 0.29% Cu, 0.005% Mo, 0.07 g/t Au and 4.95 g/t Ag in the inferred category.

The historical estimate was prepared using a three-dimensional solid to constrain the interpolation of mineralization, using a 0.1% Cu grade limit as a guide. Large internal waste zones and certain post-mineral dykes were modelled. A total of 133 drill holes totaling 38,854 metres within the modelled area were used in the estimate. Copper, molybdenum, gold and silver assays within the mineralized solid were capped at 1.8% Cu, 0.16% Mo, 0.80 g/t Au and 70 g/t Ag, respectively. Five-metre composites were calculated and used for variography. Blocks were 5 m x 5 m x 10 m and were estimated for Cu, Mo, Au and Ag by ordinary kriging. Classification as indicated or inferred was based on each block’s proximity to data and grade continuity within the mineralized solid.

Vizsla Copper considers the historical estimate to be relevant because it provides information regarding the scale and grade of mineralization identified at the Poplar Project and assists in guiding future exploration and evaluation work. Vizsla Copper considers the historical estimate to be reliable for these limited purposes because it was prepared by qualified professionals using drilling, sampling and geological information available at the time and estimation methods considered reasonable when the estimate was prepared. However, Vizsla Copper has not independently verified the historical estimate and it should not be relied upon as a current mineral resource or mineral reserve.

The historical estimate used the categories “indicated” and “inferred”. These categories appear to be generally consistent with the corresponding mineral resource categories under NI 43-101 and the CIM Definition Standards; however, Vizsla Copper has not completed the work required to verify the historical estimate as a current mineral resource.

Additional work required to verify or upgrade the historical estimate as a current mineral resource may include, as applicable, confirmation drilling, verification of historical drill hole locations and survey data, validation of the drill hole database, review and validation of historical QA/QC data, density verification, metallurgical test work, updated geological modelling, application of current CIM Definition Standards and preparation of a current mineral resource estimate and technical report in accordance with NI 43-101.

A Qualified Person has not done sufficient work to classify the historical estimate as current mineral resources or mineral reserves, and Vizsla Copper is not treating the historical estimate as current mineral resources or mineral reserves. Mineral resources are not mineral reserves and do not have demonstrated economic viability.

PALMER PROJECT

Notes on Mineral Resource Estimate

(1) Mineral Resources, which are not Mineral Reserves, do not have demonstrated economic viability. The deposits have been classified as Indicated and Inferred based on confidence in the geological model, drill spacing. The estimate of Mineral Resources may be materially affected by environmental, permitting, legal, title, market or other relevant issues. The quantity and grade of reported Inferred Resources are uncertain in nature and there has not been sufficient work to define these Inferred Mineral Resources as Indicated or Measured Resources. There is no certainty that any part of a Mineral Resource will ever be converted into reserves.

(2) Mineral resources are reported using an assumed NSR which includes prices, recoveries and payabilities cut-off grade based on metal price assumptions*, variable metallurgical recovery assumptions**, mining costs, processing costs, general and administrative (G&A) costs and variable NSR factors. Mining (US$41.3), processing (US$23.92) and G&A costs (US$11.77) and Sustaining Capital (US$15.92) totaling US$92.9/t for Underground Mining.

(*) Metal price assumptions considered for the calculation of Metal Equivalent grades are: Gold (US$/oz 2,100.00), Silver (US$/oz 28.0), Copper (US$/lb 4.50), Lead (US$/lb 0.95) and Zinc (US$/lb 1.50)

(**) Cut-off grade calculations assume variable metallurgical recoveries as a function of grade and relative metal distribution. Average metallurgical recoveries are: SW/RW Zones: Gold (76.1%), Silver (90.2%), Copper (90.3%), Lead (82.9%) and Zinc (89.2%), AG Zone: Gold (66.0%), Silver (91.0%), Copper (54.8%), Lead (83.4%) and Zinc (94.8%) .

(3) NSR Calculations for SW/RW Domains: NSR= $77.25 x %Cu + $20.32 x %Zn + $9.64 x %Pb + $0.64 x g/t Ag + $43.07 x g/t Au

(4) NSR Calculation for AG Domain: NSR=$49.04 x %Cu + $22.25 x %Zn + $10.14 x %Pb + $0.70 x g/t Ag + $37.77 x g/t Au

(5) The resources are considered to have potential for extraction using underground methodology and constrained by mineable shapes. Resources are presented undiluted and in situ and are considered to have reasonable prospects for economic extraction.

(6) Barite as reported is shown for economic potential but has not been used in the NSR value at this stage.

(7) ZnEq defined by equation SW & RW = NSR value per block / $20.32; AG = NSR value per block / $22.25 (Note Barite has been excluded from the ZnEq and NSR calculations)

(8) CuEq defined by equation SW & RW = NSR value per block / $77.25; AG = NSR value per block / $49.04 (Note Barite has been excluded from the CuEq and NSR calculations)

(9) Mineral Resources are based on validated data, which have been subjected to QA/QC analysis, using capped, composited samples at 2m. Estimation has been completed using a combination of Ordinary Kriging and Inverse Distance estimation methodologies and classified based on confidence in the underlying data and drill spacing. Mineral resource tonnages have been rounded to reflect the precision of the estimate.

(10) The mineral resources were estimated by Benjamin Parsons, BSc , MSc Geology, MAusIMM (CP) #222568 of SRK, a Qualified Person.
