Kodiak Drills 0.46% CuEq Over 111 m from Surface at the South Zone; Confirms Continuity over 950 m of Strike Length

August 21, 2025 – Vancouver, British Columbia – Kodiak Copper Corp. (the “Company” or “Kodiak”) (TSX-V: KDK, OTCQB: KDKCF, Frankfurt: 5DD1) reports the first drill results from the 2025 drill program at its 100% owned MPD copper-gold porphyry project in southern British Columbia. The program focused on near-surface infill and confirmation drill holes at the West, Adit, and South Zones using a combination of diamond and reverse circulation drilling (“RC”). Results from 22 RC holes at the South Zone totalling 2,746 metres are presented herein.

Highlights:

• Kodiak’s 2025 drilling at the South Zone confirmed near-surface copper-gold mineralization over 950 metre strike length at this extensive zone (Figures 1 & 2).
• The South Zone remains open in multiple directions and at depth, with all 2025 drill holes ending in mineralization and most drilling completed to date within 250 metres of the surface.
• South Zone drill result highlights include (Figures 1 & 2):
  • RC-AXE-25-010 intersected 0.39% Cu, 0.10 g/t Au and 1.63 g/t Ag (0.46% CuEq) over 111.3 metres from 1.5 metres to 112.8 metres, including a higher grade interval of 0.51% Cu, 0.13 g/t Au and 2.24 g/t Ag (0.62% CuEq) over 59.4 metres from 1.5 metres to 60.9 metres.
  • RC-AXE-25-016 which intersected 0.27 % Cu, 0.05g/t Au and 2.54 g/t Ag (0.33% CuEq) over 96 metres from 4.6 metres to 100.6 metres.
  • RC-AXE-25-006 which intersected 0.26 % Cu, 0.06g/t Au and 0.99 g/t Ag (0.30% CuEq) over 147.8 metres from 4.6 metres to 152.4 metres, including 0.37% Cu, 0.09 g/t Au and 1.34 g/t Ag (0.44% CuEq) over 51.8 metres from 61 metres to 112.8 metres.
• Further drill results, including from the West and Adit Zones, are expected in Q3. At both these zones substantial near-surface, high-grade mineralization was intersected in past drilling.
• The 2025 drill results will be used to develop a Mineral Resource Estimate (“MRE”) for the South, West and Adit Zones, expected in Q4. Together with the MRE for the Gate, Ketchan, Man and Dillard Zones released in Q2 (news release June 25, 2025) this will complete the initial MRE for the MPD Project.
• The 2025 drill program at MPD totalled 5,003 metres in 31 RC drill holes (3,598 metres) and 13 diamond drill holes (1,405 metres) and was successfully completed on time and on budget. Field work for the remainder of the season is focused on detailed geological mapping, prospecting and geological investigation around known zones and priority targets, including VRIFY Areas of Interest.
  

“We are very encouraged by the consistency of mineralized intercepts over a substantial strike length at the South Zone,” said Claudia Tornquist, President and CEO of Kodiak. “These results not only confirm historic drilling but also significantly strengthen our confidence as we move toward adding the South Zone to our Mineral Resource estimate for the MPD Project. We are expecting more results in Q3 from the West and Adit Zones, which had some of the highest-grade near-surface intercepts on the project in previous drilling, and are looking forward to seeing how these zones will contribute to the full Mineral Resource.”

Drilling at the South Zone confirmed historic drilling results and improved the geological confidence in areas of lower drill density. The South Zone consists of altered and mineralized volcanic rocks and altered, coarse-grained monzonite porphyry stocks. Mineralization is predominantly copper with lesser gold and minor molybdenum. The South Zone, in combination with the historical Adit and Mid Zones, correlates well with a 2.3 kilometer long copper-in-soil anomaly and related Induced Polarization chargeability responses and these zones are interpreted to form a single, large system. The Mid Zone is now considered to be an extension of the South Zone.

A track mounted Super Hornet reverse circulation drill rig supplied by Northspan Ltd based in Kelowna BC was used to drill at the South Zone. Representative samples of drill cuttings were collected at ten foot intervals and the material was homogenized and split in the field to produce representative samples of approximately 5 kg of material. Samples were then submitted to Actlabs in Kamloops for analysis.

* Copper equivalent grades (%CuEq) are for comparative purposes only to express the combined abundance of copper, gold, and silver. Metallurgical recovery is assumed as 82% for copper, 60% for gold and 54% for silver as determined by Kodiak metallurgical testing as stated in the Mineral Resource Estimate (see News Release June 25, 2025). Metal prices used in calculations are: US$4.20/lb copper, US$2,600/oz gold, and US$30/oz silver, using the formula: CuEq = Cu(%) + Au(g/t) x 0.6606 + Ag(g/t) x 0.0069

**Intervals are downhole drilled core intervals. Drilling data to date is insufficient to determine true width of mineralization.

Sampling, Laboratory Analyses and QA/QC Procedures

The RC drill chips are sampled and assayed every 10 feet (3.04 metres). Laboratory samples are approximately 5kg and a 5kg archive sample is also retained as reference. All samples are delivered to accredited laboratory Activation Laboratories Ltd. (Actlabs) Kamloops, BC, for preparation and Fire Assay prior to being shipped to their Ancaster, Ontario Laboratory for Multi-element analysis. The samples are analyzed for gold by fire assay fusion with an AA finish. If samples return gold values over 10ppm, samples are reanalysed by fire assay with gravimetric finish. Samples then undergo four acid digestion and ICP-OES and ICP-MS analysis for 48 elements. Samples that return copper values above 10,000 ppm are further analysed using a “near-total” digestion, ICP-OES package. Actlabs meets all requirements of International Standards ISO/IEC 17025:2015 and ISO 9001:2015 for analytical procedures. In addition to Actlabs quality assurance-quality control (QA/QC) protocols, Kodiak implements an internal QA/QC program that includes the insertion of sample blanks, duplicates, and certified reference materials, at a rate of one per ten samples. 

Dave Skelton, P.Geo., Vice President Exploration and the Qualified Person as defined by National Instrument 43-101, has approved and verified the technical information used in this news release.

Change to the Board of Directors

Kodiak also announces the resignation of Kevin Tomlinson as a director of the Company effective August 25^th, 2025 due to a requirement to reduce the number of boards he serves on.  Mr. Tomlinson will remain an advisor of the Company.

About Kodiak Copper

Kodiak is focused on its 100% owned copper porphyry projects in Canada and the USA that have been historically drilled and present known mineral discoveries with the potential to hold large-scale deposits. Kodiak Copper’s most advanced asset is the 100% owned MPD copper-gold porphyry project in the prolific Quesnel Terrane in south-central British Columbia, Canada, a mining district with producing mines and excellent infrastructure. MPD exhibits all the hallmarks of a major, multi-centered porphyry district with the potential to become a top-tier mine. To date, drilling has outlined seven substantial mineralized zones across the property, and Kodiak is delivering an Initial Resource estimate for MPD in 2025. The estimate for the first four mineralized zones has already highlighted the project’s scale and potential. Drill results on the remaining three zones from Kodiak’s 2025 exploration program will be incorporated into the full Initial Resource estimate, expected by year end. With known mineralized zones open to expansion and multiple untested targets, Kodiak continues to systematically explore the district-scale potential of MPD to build critical mass and make the next discovery.

Kodiak’s founder and Chairman is Chris Taylor who is well-known for his gold discovery success with Great Bear Resources. Kodiak is also part of Discovery Group led by John Robins, one of the most successful mining entrepreneurs in Canada.
