Kodiak Drills High-Grade Mineralization from

Surface at the Adit Zone Including 79m of

0.69% CuEq Ending in 27m of 1.62% CuEq

Vancouver, British Columbia--(Newsfile Corp. - September 2, 2025) - Kodiak Copper Corp. (TSXV:

KDK) (OTCQB: KDKCF) (FSE: 5DD1) (the "

Company

" or "

Kodiak

") announces additional drill results

from the 2025 drill program at its 100% owned MPD copper-gold porphyry project in southern British

Columbia. The program focused on short, 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

nine RC holes totaling 850 metres completed at the Adit Zone are presented herein.

Highlights:

Results confirm

shallow, high-grade mineralization at the Adit Zone

.

Highlight drill intersections include:

RC-AXE-25-026 intersected

0.63% Cu, 0.05 g/t Au and 4.13 g/t Ag (0.69% CuEq) over

78.6

metres from 0 metres to 78.6 metres, including a higher-grade interval of

1.59% Cu,

0.01 g/t Au and 4.29 g/t Ag (1.62% CuEq) over 26.8

metres from 51.8 metres to the end

of hole at 78.6 metres.

RC-AXE-25-028 intersected

0.42% Cu, 0.03 g/t Au and 3.44 g/t Ag (0.46% CuEq) over

93 metres

from 7.6 metres to 100.6 metres, ending in mineralization.

Drilling at the Adit Zone has intersected mineralization over a

strike length of approximately

550 metres and the zone remains open in multiple directions

The Adit Zone is open at depth

and past drilling

encountered mineralization to a depth of

350 metres

(

see November 19, 2024 news release

). The current drill program was designed to

test near-surface mineralization for resource modelling, with most holes ending in mineralization.

Final results

from the 2025 drill program are expected

in late Q3

.

The drill hole data will support a

Resource Estimate for the Adit Zone

as part of the initial MRE

for the MPD Project planned for Q4 2025.

Claudia Tornquist, President and CEO of Kodiak said, "The Adit Zone continues to deliver excellent

grades close to surface as we advance and grow the MPD project. With our drilling to date, we were

able to significantly extend the historic mineralized envelope at the Adit Zone and it is still open in

multiple directions with the potential for further growth. This year's program was designed to infill and

confirm shallow mineralization with short holes, an objective we successfully accomplished."

Adit is a diorite porphyry system characterized by supergene enrichment and copper oxide

mineralization in the upper 100 metres transitioning to sulphide mineralization at depth. Local faulting

and fracturing near surface contributed to challenging ground conditions and five of the drill holes

reported herein did not reach their planned depth. The Adit Zone is interpreted to be part of a larger

system that includes the historical South and Mid Zones. The system correlates well with a 2.3-kilometer-

long copper-in-soil anomaly and related induced polarization chargeability responses.

*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.

†

RC-AXE-25-030 from 88.4 metres to 126.5 metres (EOH) was removed from the weighted interval calculation due to poor sample quality.

Sampling, Laboratory Analyses and QA/QC Procedures

All RC chip 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

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.
