Business Combination

VANCOUVER, BC

,

/CNW/ - Cascadia Minerals Ltd. ("

Cascadia

") (TSXV: CAM)

(OTCQB: CAMNF) and Granite Creek Copper Ltd. ("

Granite Creek

") (TSXV: GCX) (OTCQB:

GCXXF) are pleased to announce the acquisition by Cascadia of all of the issued and outstanding

common shares of Granite Creek (the "

Granite Creek Shares

") pursuant to a court-approved plan

of arrangement under the Business Corporations Act (

British Columbia

) (the "

Arrangement

"). The

Arrangement, which became effective as of today's date, merges Granite Creek into Cascadia to

create a leading

Yukon

copper-gold exploration and development company.

Graham Downs

, President and CEO of Cascadia, commented: "We are very excited to complete

this merger, and we welcome Granite Creek Shareholders to Cascadia. The combined property

portfolio provides our shareholders with exposure to an advanced-stage copper-gold deposit at the

Carmacks Property and a compelling collection of discovery-stage copper-gold and epithermal gold

projects throughout

Yukon's

underexplored Stikine Terrane. Planning is well underway for a fully-

funded fall drill program at

Carmacks

that will focus on step-out drilling near high-grade portions of

the deposit. In the meantime, crews are conducting prospecting work at our Macks, Milner, Idaho

Creek and Rosy properties while we await results from our spring drilling at Catch".

Upon completion of the Arrangement, each Granite Creek shareholder received 0.25 (the

"

Exchange Ratio

") of a Cascadia common share (each whole share, a "

Cascadia Share

") in

exchange for each previously held Granite Creek Share, with Cascadia issuing a total of 53,070,848

million Cascadia Shares to former Granite Creek shareholders. Pursuant to the transaction,

previously outstanding stock options of Granite Creek have been exchanged for 3,747,500 stock

options of Cascadia, and warrants to acquire Granite Creek Shares have been adjusted to permit

their holders to acquire a total of 11,036,291 Cascadia Shares, in each case by applying the

Exchange Ratio to the number and exercise prices of such options and warrants.

Timothy Johnston

, Granite Creek's former President and CEO has joined Cascadia's board of

directors.

James Sabala

and Kurt Allen have resigned from Cascadia's board of directors. Cascadia

About Cascadia

Cascadia's flagship asset is the Carmacks Project in the high-grade

Minto

copper district in

Yukon

Territory, Canada

. The project is located south of and within 35km of the past-producing

Minto

mine,

which was recently acquired by Selkirk Copper Mines. The Carmacks Project hosts a Measured and

Indicated Resource containing 651 Mlbs of copper and 302 koz of gold (36.3 million tonnes grading

0.81 % copper, 0.26 g/t gold, and 3.23 g/t silver and 0.01% molybdenum) with a 2023 PEA

demonstrating positive economic potential (

$230.5 M

Post-Tax NPV

(5%)

and 29% Post-Tax IRR).

Cascadia also has a pipeline of discovery stage copper-gold properties throughout the Yukon Stikine

Terrane including its Catch Property, which hosts a copper-gold porphyry discovery where inaugural

drill results returned broad intervals of mineralization (

116.60 m

of 0.31% copper with 0.30 g/t gold).

Catch exhibits extensive high-grade copper and gold mineralization across a 5 km long trend, with

rock samples returning peak values of 3.88% copper, 1,065 g/t gold, and 267 g/t silver.
