Cascadia Provides Drilling Update for its

Catch Copper-Gold Porphyry Project, Yukon

VANCOUVER, BC

,

May 30, 2024

/CNW/ - Cascadia Minerals Ltd. ("

Cascadia

") (TSXV: CAM)

(OTCQB: CAMNF) is pleased to provide an update on the ongoing diamond drill program at its

Catch Property. The Catch Property hosts one of

North America's

newest copper-gold porphyry

discoveries, with extensive mineralization at surface. The property is located in central

Yukon

, only

10 km from a paved all-season highway and powerline, within an extension of the Stikine terrane – a

key geological setting which extends from the Golden Triangle in

British Columbia

to

Yukon

. The

Catch Property has never been historically explored, with Cascadia conducting the first-ever

diamond drill program in fall 2023, which resulted in the discovery of the Spark Zone.

Hole CA-24-006 Section (CNW Group/Cascadia Minerals Ltd.)

Spark Zone Diamond Drilling Highlights:

The first 2024 diamond drill hole (CA-24-006)

stepped out

315 m

from 2023 discovery hole

CA-23-002 and

intersected

140 m

of pyrite-chalcopyrite mineralization

(Figure 1);

Mineralization in CA-24-006

contains greater sulphide abundance (pyrite-chalcopyrite)

than observed in hole CA-23-002

, which returned

116.60 m

of 0.31% copper with 0.30 g/t

gold;

CA-24-006 intersected zones of

potassic alteration

associated with

disseminated

(Figure 2)

and vein hosted chalcopyrite-pyrite

(Figure 3);

Hole CA-24-006 targeted a coincident Induced Polarization ("IP") chargeability and resistivity

high within a larger and

open-ended 1.4 km long IP chargeability anomaly

(Figure 4);

The second 2024 drill hole (CA-24-007) is now underway, testing a

similar IP chargeability

and resistivity high

150 m

north of CA-23-002

(Figure 5); and,

Planning is underway to

extend the 2024 drill program to step out on CA-24-006

.

"We are very excited to have hit additional mineralization on such a large step-out from last year's

discovery at the Spark Zone. The amount of observed sulphide minerals, coupled with the

favourable alteration we are now seeing, clearly demonstrates that this is a large mineral system

with significant copper-gold potential. Mineralization at Catch is suggestive of an Alkalic Porphyry,

similar in nature to the Red Chris mine in Northern BC and the Cadia-Ridgeway system in

Western

Australia

,"

said

Graham Downs

, Cascadia's President and CEO.

"Our crews are working to quickly

process this core and get assays underway as soon as possible, with several batches of core

already at the lab. In the meantime, drilling continues at the Spark Zone, where extensive

geophysical anomalies remain open in all directions. It is critical to remember that this is only the

third drill hole ever completed at this kilometer-scale target, with both holes last year returning

significant mineralization. We see great potential at Catch and are evaluating options to extend the

drilling program to complete additional step-out holes."

Cascadia cautions that visual estimates of mineral abundance should never be considered a proxy or

substitute for laboratory analyses where concentrations or grades are the factor of principal

economic interest. Laboratory assays are required to determine the presence and grade of any

contained mineralization within the reported visual intersections of copper sulphides. The company

will update the market as soon as laboratory analytical results become available.

2024

Diamond Drilling

Diamond drilling is underway at the Spark Zone where 2023 diamond drill hole CA-23-002

intersected

116.60 m

of 0.31% copper with 0.30 g/t gold. The first 2024 diamond drill hole, CA-24-

006, ended at

570 m

and the second drill hole (CA-24-007) is underway. The Spark Zone is defined

by a 700 x

700 m

magnetic low coincident with a 1,400 x

600 m

IP chargeability high and rock

samples returning up to 3.88% copper with 30.0 g/t gold at surface within a large copper in soil

anomaly.

CA-24-006 was collared

315 m

southeast of hole CA-23-002 (figure 1), targeting a stronger and

broader portion of the IP chargeability anomaly (figure 4), coincident with a zone of high resistivity.

The hole encountered a variety of host rock types including quartz-feldspar porphyry, diorite, diorite

porphyry, basalt and gabbro. The top

290 m

of the hole displayed broad propylitic alteration

(chlorite-epidote-pyrite ± hematite) of dominantly basalt and diorite with a clear increase in intensity

with depth. A

140 m

zone of sericitic (quartz-sericite-pyrite) to potassic alteration (biotite) with

disseminated to vein hosted pyrite-chalcopyrite mineralization was encountered from 290 to

430 m

in

all host rock types. Strong propylitic alteration was observed again from 430 to

550 m

dominantly

within gabbro before encountering a large fault towards end of hole.

There is a pervasive late-stage chlorite overprint on the mineralization making identification of

primary alteration difficult. In addition, structural deformation deforms the mineralization; likely from

the nearby 1,000+ km long Teslin-Thibert fault. Further petrographic studies will be undertaken in the

coming months to validate initial geology and alteration logs.

Hole CA-24-007 is collared off the same drill pad as CA-23-002 and will fan eastward and step out

150 m

on the known copper-gold mineralization at depth. This hole will test the projected extension

of mineralization from hole CA-23-002 towards an area of high IP chargeability and stronger

resistivity (figure 5), which may represent potassic alteration.

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 and 30.00 g/t gold.

In addition to Catch, Cascadia is conducting exploration work at its Mack's Copper and Milner

properties – recently staked Catch analogues within

Yukon's

Stikine Terrane – as well as the Sands

of Time property in the

Yukon

and the PIL Property in

British Columbia

, all of which have additional

copper porphyry targets. Cascadia has approximately 45 million shares outstanding and its largest

shareholders are Hecla Mining Company and

Barrick Gold

.

QA/QC

Analytical work for 2023 samples was completed by ALS Canada Ltd, with sample preparation in

Whitehorse

,

Yukon

and geochemical analyses in

North Vancouver, BC

. Rock and core samples

were fine crushed before a 250-gram split was pulverized to better than 85% passing 75 microns.

Gold was determined for rock samples by the PGM-ICP24 procedure which involves fire assay

preparation using a 50-gram charge with an inductively coupled plasma-atomic emission

spectroscopy finish ("ICP-AES"). Soil samples were dry-screened at 180 micron, with analysis

conducted on the fine fraction. Gold was determined for soil and silt samples by the Au-ICP21

method, which involves fire assay preparation with a 30-gram charge followed by an ICP-AES finish.

Multi-element data for 48 elements was determined for all samples by the ME-MS61 procedure,

which involves a four-acid digestion followed by ICP-AES and inductively coupled plasma-mass

spectrometry. Overlimit values for copper were determined by the ME-OG62 procedure, which

involves a four-acid digestion followed by ICP-AES analysis.

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

and gold have been encountered in core, silt, rock and soil samples in these target areas.
