Coast Copper Signs MOU with five other

Companies to Study Viability of Hub and

Spoke Mill Complex at a Permitted Site at

Kitsault, BC

TSX. V: COCO

VANCOUVER, BC

,

March 21, 2023

/CNW/ -

Coast Copper Corp. ("Coast Copper"

or the

"Company")

(TSXV: COCO) is pleased to announce that it has signed a Memorandum of

Understanding ("

MOU

") with BWCG Holdings Ltd., Blackwolf Copper & Gold Ltd. (TSXV: BWCG),

Dolly Varden Silver Corp. (TSXV: DV) (OTC: DOLLF), New Moly LLC. and Goliath Resources Ltd.

(TSXV: GOT) (OTCQB: GOTRF) (Frankfurt: B41F) (collectively, the "

Companies

"), to jointly study

the viability of using New Moly LLC's Kitsault project ("

Kitsault

" or the "

Project

") as the potential

site for a centralized polymetallic processing facility that could accept mineralized material from the

Companies' respective deposits ("

Kitsault Polymetallic Mill

"), working as a hub and spoke mill.

MOU

The proposed site at Kitsault previously hosted a molybdenum mine. Within the past decade, Kitsault

received Canadian Federal and Provincial Permits and given the buoyant molybdenum market, New

Moly LLC is now considering funding requirements to restart a larger scale project. The Project is in

northern

British Columbia

, approximately 140 kilometers north of

Prince Rupert

. The Project is

located on the BC Hydro grid, has road access to the Nass Valley as well as tidewater access. The

Kitsault Polymetallic Mill concept may assist to enhance and de-risk the potential restart of Kitsault.

The Companies have engaged Fuse Advisors Inc. ("

Fuse Advisors

") to complete an initial

assessment of the technical viability of the Kitsault Polymetallic Mill concept. By reviewing the

respective metallurgical test work completed at the various deposits, Fuse Advisors will assess the

potential for blending or batching mineralized material, potential process flowsheets, potential

throughputs from the various deposits and associated mill sizing and timelines.

Adam Travis

, Coast Copper's CEO comments

:

"We are very pleased to have been included in the

study of the Kitsault Polymetallic Mill. This could greatly increase synergies between the

Companies, reduce respective capital costs as well as reduce permitting timelines and risks by

using a permitted site location. Coast Copper is looking at this assessment as a viable option if

and when our optioned Empire Mine property ever gets to the point of production."

"

Nisga'a Lisims Government has had initial discussions with Blackwolf on the concept of a hub and

spoke mill at the site of the Kitsault Project. We look forward to further consultation on this and

other natural resource opportunities within the Nass Area which is subject to the Nisga'a Final

Agreement where we have constitutionally protected title and rights

" said

Charles Morven

,

Secretary-Treasurer for Nisga'a Lisims Government.

The Companies will jointly share the costs of this assessment. Fuse Advisors is a

Vancouver

based

consultancy group that provides project management and technical advisory services to development

stage companies in the resource sector.

Empire Mine Property

The Empire Mine Property (the "

Property

") was optioned by Coast Copper in

September 2020

.

Coast Copper can purchase a 100% interest in the Property by making staged cash and share

payments. The Property covers 23 mineral occurrences, including 3 past producing open pit and two

underground past producing mines for magnetite, copper, gold and silver.

The Merry Widow deposit has a National Instrument 43-101 Historical measured and indicated

resource of

960,000 tonnes at 2.03 g/t gold, 5.64 g/t silver, 0.34% copper, 0.023% cobalt and

16.1% iron (0.50 g/t gold cut off)

which was completed

November 2008

Gary Giroux

Historical records and maps from Cominco Ltd. In 1972, indicate the Benson Lake Mine

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

(no Au grade estimated) to the 2100 level as of

December

31, 1972

classified as "inferred"

On

January 18, 2023

Coast Copper announced it had updated its geological model based on

historical work, Coast Copper's drilling and surface work as well as work completed by Dr.

Jim

Oliver

. The new model highlights the potential for significant copper-gold-iron mineralization to

continue adjacent to and up to

500 m

in elevation below the Merry Widow Pit mineralization, as well

as continuing along the trend of these regional features and down dip towards the Benson Lake

Mine. The stacked thrust model is consistent with both local and regional observations and

correlates well with copper-gold-iron mineralization recorded in drill core and historical observations

from underground. Surface geological observations and mapping, ore mineral occurrences,

underground workings and drillhole data also indicate that these thrust horizons and associated

mineralization occur along strike over a 5 km northerly trend.

The model indicates potential for multiple, near-surface targets between the Merry Widow open pit

and the Benson Lake underground. Our understanding of these controls and their relationship with

intersecting structures will prove invaluable in guiding future drill programs.

producing underground mines that yielded iron, copper, gold and silver. Coast Copper's other

properties include its 100% owned Knob Hill NW Property located on northern Vancouver Island, its

Home Brew and Shovelnose South Properties in central B.C., and its Scottie West Property located

in the "Golden Triangle" of northern B.C. Coast Copper's management team continues to review

NI 43-101 Technical Report: Giroux, G.H., & Raven, W. (

November 30, 2008

). Technical Report

on the Copper Gold Resources for the Merry Widow Property. Filed on SEDAR

January 22,

2009

. The 2008 Grand Portage resource estimate was completed by

Gary H. Giroux

, P.Eng,

MASc, of Giroux Consulting Ltd. in

Vancouver, B.C.

The estimate was based on a 3D

geological model integrating 4,448 metres of diamond drilling of 43 drill holes, 2,290 assays,

with 104 down-hole surveys collected between June and

December 2006

. The resource was

reported utilizing gold cut-off grades ranging from 0.10 g/t to 3.00 g/t gold, as more particularly

set out in the report. A complete copy of the report is available on Grand Portage's public filings

on SEDAR (

www.sedar.com

). A gold cut-off grade of 0.50 g/t gold was selected as

representing one possible mining scenario. For the purposes of the calculations, lognormal

cumulative frequency plots were used to assess grade distribution to see if capping of high

values was required and if so at what levels. For all elements, capping levels were established

based on the individual grade distributions as follows: Gold -- a total of 18 gold assays were

capped at 32.0 g/t gold, Silver --a total of 9 silver assays were capped at 165 g/t silver, Copper

-- a total of 7 assays were capped at 11.7% copper, Cobalt -- a total of 5 assays were capped

at 0.48% cobalt, Iron -- all iron assays were capped at 50% iron (the analytical detection limit).
