Cascadia Commences First Drill Test of 1,065 g/t Gold Outcrop at Amp Zone Catch Copper- Gold Property, Yukon

Drill Results

Cascadia Commences First Drill Test of 1,065

g/t Gold Outcrop at Amp Zone Catch Copper-

Gold Property, Yukon

VANCOUVER, BC

,

May 20, 2025

/CNW/ - Cascadia Minerals Ltd. ("

Cascadia

") (TSXV: CAM)

(OTCQB: CAMNF) is pleased to announce the commencement of its fully-funded exploration

program for the 2025 field season. Crews have recently mobilized to the Catch copper-gold

porphyry and gold-silver epithermal project, where work is underway to follow up on a

new 1,065

g/t gold outcrop discovery made in 2024

and other copper-gold target areas.

Amp Zone 2025 (CNW Group/Cascadia Minerals Ltd.)

Highlights

Amp Zone Epithermal Gold-Silver±Copper Target

Prospecting and mapping underway to follow up on 2024 discovery of a

new undrilled

outcrop returning

1,065 g/t gold with 267 g/t silver

(Figure 1);

Hand trenching and sampling will focus on a

20 m

long area where the

average grade of

20 outcrop samples was 73.45 g/t gold with 19.5 g/t silve

r (Figure 1);

Sampling will also follow-up on an area

70 m

to the north which

returned 2.13% copper in

outcrop

(Figure 1);

Diamond drilling to commence in late May

, totaling

400 m

in two or three holes targeting

the high-grade trend (Figure 1); and

Grid soil sampling underway to refine a trend of anomalous results

including 1,128 ppb

and 471 ppb gold in soil

and

531 ppm copper in soil

(Figures 2-3).

Volt Zone Porphyry Copper-Gold Target

Prospecting and surficial mapping underway to identify the bedrock source of a 500 x

500

m

area of copper-gold mineralization in float, with rock samples returning

3.03% copper

with 4.46 g/t gold, 2.83% copper with 6.07 g/t gold, and 14.60 g/t gold with 0.42%

copper

(Figures 2-3); and

Diamond drilling planned totaling up to

600 m

testing the bedrock source of mineralization

(Figure 4).

Prospecting will also occur at numerous underexplored areas throughout the property with

compelling copper-gold±molybdenum soil anomalies.

"

We're very excited to have our 2025 exploration at Catch underway,

" stated Cascadia's President

and CEO,

Graham Downs

, "

The discovery in 2024 of extremely high-grade gold-silver

mineralization at the Amp Zone is a game changer for Cascadia. Crews are conducting detailed

prospecting and mapping of outcrops at Amp to refine drill targeting and drill pad placement. With

diamond drilling scheduled to begin before the end of the month, we will soon see what these high-

grade rocks look like at depth. The next priority for crews will be systematic exploration of the Volt

Zone, which has extensive float mineralization across a broad geochemical anomaly. Our team is

confident we can localize the bedrock source of this mineralization for drilling after the Amp holes

are completed.

Catch Property Exploration

The 119 km

2

Catch Property is located in central

Yukon

, 50 km southeast of the town of

Carmacks

,

within the Traditional Territory of the Little Salmon Carmacks First Nation, in an underexplored part

of the Stikine Terrane – a key geological terrane which extends from the Golden Triangle in

British

Columbia

into

Yukon

. The property is only 10 km from an all-season highway and powerline and has

no documented historical exploration before 2020.

Work in 2025 is planned to focus on the Amp and Volt zones. At the Amp Zone, two to three shallow

drill holes, totaling approximately

400 m

, will test high-grade epithermal gold-silver mineralization

discovered in outcrop in 2024. One sample returned

1,065 g/t gold with 267 g/t silver

, with nearby

follow-up samples returning

187.0 g/t gold with 33.9 g/t silver

, and

141.0 g/t gold with 45.2 g/t

silver

. These samples are located within a highly silicified basalt associated with elevated arsenic

and antimony geochemistry. Significant copper mineralization has also been encountered in rock

samples at Amp, with 2023 sampling returning

2.13% copper

in outcrop. Crews will also conduct

prospecting and mapping at this target to better understand the distribution of mineralization, and the

relationship between the high-grade gold and copper zones.

At the Volt Zone, located 1 km north of Amp, drilling will target the as-yet unidentified source of

significant copper-gold mineralization in float across a 500 x

500 m

area, where 258 rocks returned

an average grade of

0.32% copper with 0.70 g/t gold

. This mineralization is located within a

landslide which has shifted it from source by up to

250 m

. Crews will begin by completing a

comprehensive mapping and surficial geology study to refine drill targeting, with up to

600 m

of

diamond drilling planned.

The Spark Zone, the focus of Cascadia's 2024 drilling, remains open in multiple directions. A

comprehensive core review was conducted this spring, which has identified a distinct north-east

trend of mineralization. This corresponds well with a geophysical interpretation which identified key

structural controls in the area and a string of potential intrusive centers extending to the northeast

from the drilled target. Hand pitting will be completed to sample bedrock in these areas, with

additional geophysics and diamond drilling to be considered later in the season, if results warrant.

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.

In addition to Catch, Cascadia is conducting exploration work at its Macks and Milner properties –

recently staked Catch analogues within

Yukon's

Stikine Terrane which have additional copper

porphyry targets. Cascadia has approximately 70 million shares outstanding and its largest

shareholders are Hecla Mining Company,

Michael Gentile

and

Barrick Gold

.

Results referenced in this release represent highlight results only. Below detection values for gold,

copper, silver and molybdenum have been encountered in soil and rock samples in these target

areas.
