About Cascadia

Cascadia is a Canadian junior mining company focused on making new copper and gold discoveries

the

Yukon

and

British Columbia

. Cascadia's flagship Catch Property in the

Yukon

hosts a brand-new

copper-gold porphyry discovery where inaugural drill results returned broad intervals of

mineralization, including

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.

Granite Creek'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

(5%)

and 29% Post-

The Mineral Resources disclosed here are referenced from the 2023 Technical Report on the

Carmacks Project Preliminary Economic Assessment, authored by SGS Canada Inc. for Granite

Creek Copper, and have not been independently reviewed by Cascadia. Pricing for the Carmacks

Project PEA base case economic analysis was US

$3.75

/lb copper, US

$1,800

/oz gold, and US

$22

/oz silver at an exchange rate of

$1

:

US$0.75

. For more details on the economic analysis, refer

to the 2023 Technical Report on the Carmacks Project Preliminary Economic Assessment, authored

by SGS Canada Inc. for Granite Creek Copper. The results of the

Carmacks

preliminary economic

assessment are preliminary in nature, it includes inferred mineral resources that are considered too

speculative geologically to have the economic considerations applied to them that would enable them

to be categorized as mineral reserves, and there is no certainty that the preliminary economic

assessment will be realized.
