Coast Copper Highlights its Northern

Vancouver Island Projects and Congratulates

Northisle

VANCOUVER, BC

,

Feb. 26, 2026

/CNW/ -

Coast Copper Corp. ("Coast Copper" or the

"Company") (TSX-V: COCO

) is pleased to highlight its mineral claim holdings on northern

Vancouver Island and wishes to congratulate its neighbor Northisle Copper and Gold Inc.

("

Northisle

") on the significant announcement made by the B.C. provincial government on February

23, 2026 noting that its North Island project

2

will receive B.C. Critical Minerals Office support as an

advanced project

Group/Coast Copper Corp.)

The Ministry of Mining and Critical Minerals of the Province of B.C. has selected Northisle's North

Island project to work with the Critical Minerals Office to support early co-ordination as the project

prepares for environmental assessment and future permitting processes. The Critical Minerals Office

works with selected advanced project proponents to accelerate their permitting processes by

helping co-ordinate First Nations and community engagement, identify regulatory requirements early,

align permitting pathways and support readiness for future environmental assessment and regulatory

processes.

Adam Travis, CEO, comments

: "I grew up on Vancouver Island and have explored it since the

early 1990s when BHP's Island Copper mine was still in production and was Canada's second

largest copper mine at the time. I have been watching Northisle advance its project in the same belt.

This announcement highlights the importance of these projects for critical minerals and commitments

to modern exploration, community engagement and collaboration with all levels of government and

First Nations, which we also share. Coast Copper's 2026 exploration programs are expected to

commence this spring, starting with an Induced Polarization geophysical survey at our Copper Kettle

project which sits between Northisle's North Island project and BHP's former producing Island

Copper mine. Coast Copper is well-funded to undertake this work because of its business model

which generates cash from the optimization and sale of non-core projects for cash and shares.

Planning is also underway for more extensive exploration in 2026."

NORTHERN VANCOUVER ISLAND PORPHYRY Copper ("Cu") – Molybdenum ("Mo") +/- Gold

("Au") and Massive Sulphide Cu - Au - Magnetite

On northern Vancouver Island, a 50-kilometer ("

km

") east-west trending corridor hosts a series of

Early Jurassic mineralized Cu - Au - Mo porphyry systems, mostly held by Northisle

2

. However, at

its western end, Coast Copper owns the Knob Hill NW property which abuts Northisle's Hushamu

and Red Dog and NW Expo deposits and at the eastern end, Coast Copper owns the Copper Kettle

property, which sits adjacent to BHP's Island Copper mine lease

2

. Coast Copper's Empire Mine

project is the most advanced brownfield high-grade Cu-Au-magnetite massive sulphide deposit

project on northern Vancouver Island and is located approximately 30 km south-southeast of the

Island Copper Mine (see Figure 1).

Copper Kettle Project Porphyry Cu - Mo +/- Au Target

The 5,225-hectare ("

ha

") Copper Kettle property (see Figure 1) hosts the NW Zone, one of the six

genetically related Jurassic calc-alkaline porphyry systems that form the "Island Copper Cluster"

which occupies a 10 km long structural-magnetic anomaly with the NW Zone being the only member

located outside BHP's Island Copper mining lease

4

. From 1983 to 1989 BHP drilled 31 diamond

holes (9,072 meters ("

m

")) and 10 percussion holes (789.5 m), outlining a buried system 1.8 km long

and 800 m wide. Seventeen drillholes returned significant copper and molybdenum values; nine of

which ended in mineralization, confirming this system remains open to depth (see news release

dated September 8, 2025). Highlights from BHP's previous drilling include 277.4 m assaying 0.20%

Cu and 0.018% Mo in hole E-64, 91.5 m assaying 0.57% Cu and 0.017% Mo in hole E-69 and 88.4

m assaying 0.38% Cu and 0.029% Mo in hole W-6.

Recent work by the Company included surface rock and soil sampling and an Audio Magnetotellurics

("

AMT

") survey which highlighted that previous BHP drilling has potentially only tested a small area

of a much larger porphyry system (see news release dated February 18, 2026).

Empire Mine Project High-Grade Massive Cu-Au-Magnetite Deposits

The Empire Mine project now totals approximately 17,186 ha over a 25 km prospective trend

covering 30 Minfile occurrences of which 3 of them are past producing open pit mines and 2 of them

are past producing underground mines for copper, gold, magnetite and silver (see Figure 1).

In May 2023, Coast Copper published a high-grade, starter mineral resource estimate for the Merry

Widow pit which Coast Copper believes can be expanded with further drilling. The Merry Widow

inferred resource hosts 594,019 tonnes grading 0.51% Cu, and 3.52 grams per tonne ("

g/t

") Au

(see press release dated May 23, 2023). Historical records and maps from Cominco Ltd. in 1972,

indicate the Benson Lake mine (1 km east of the Merry Widow pit) hosts 454,500 tonnes at 0.59 g/t

Au and 1.3% Cu classified as "measured and indicated" and a further 2,700,000 tonnes at 1.7% Cu

5

(no gold grade estimated) to the 2100 level as of December 31, 1972 classified as "inferred". While

Coast Copper notes that Cominco's historical results are not NI 43-101 compliant and have not been

verified by the Company's QP, these combined historical Benson Lake resources total approximately

3.154 million tonnes and will help guide Coast Copper's exploration programs.

In 2025 the Company conducted modest surface exploration programs and continued to consolidate

holdings in the area with the addition of 3 claims (61.8 ha) covering the Clancy and Pilgrim minfile

occurrences.

Knob Hill NW Project Porphyry Cu - Au +/- Mo Target

The Company has continued to maintain and advance its Knob Hill NW property located at the

western end of Northisle's property and within 4 km of Northisle's NW Expo Deposit (see Figure 1).

Coast Copper completed modest stream sediment, soil and rock sampling programs in 2025. This

work along with previous work by the Company has highlighted elevated copper in soils and rock

samples in the southwest area of the property around magnetic highs and strongly anomalous gold-

in-stream sediment sampling such as KH2024MM-006 which returned 1,400 ppb Au draining the

eastern side of the property (see press release dated September 23, 2024).

NEXT STEPS

Copper Kettle Project -

The Company is planning to conduct a 25 km detailed Induced Polarization

survey, followed by a conditional 10-site diamond drill program based on the exciting results of its

surface and AMT survey work indicating that BHP's earlier drill programs only tested a small portion

of the overall much larger porphyry system.

Empire Mine Project -

The Company anticipates conducting further Controlled Source Audio-

frequency Magnetotellurics ("

C.S.M.A.T.

") ground geophysical surveys (see news release dated

January 23, 2024) to refine drill targets on its Benson and Old Sport mine high-grade Cu - Au -

magnetite horizons.

Knob Hill NW Project -

The Company is planning on conducting further surface programs to test the

elevated copper-in-soil anomalies associated with magnetic highs in the southwestern portion of the

property as well as continuing to refine and explain the significant gold-in-stream sediment anomalies

along the eastern side of the property.

About Coast Copper Corp.

Coast Copper's flagship projects are the Copper Kettle post-discovery Cu-Au-Mo project located in

the Island Copper Cluster on northern Vancouver Island, the former producing Cu-Au Empire mine

also located on northern Vancouver Island and the former producing Emerald and Virginia Silver

mines located near the Huckleberry mine and Smithers in northern B.C. Coast has an additional 18

projects in B.C. that are available for acquisition, partnering or option that are strategically located in

seven advanced mining camps that include the Toodoggone, Golden Triangle Anyox, Goliath

Resources (Golddigger), Babine, Bralorne and Sullivan camps providing exposure and leverage to

millions of dollars being spent on neighboring properties. Coast Copper's strategy is to optimize the

value of each mineral property within our portfolio through a combination of prospect generation and

discovery focused, high-impact exploration while minimizing share dilution through active deal-

making.
