Sept. 1, 2026
/CNW/ -- Cascadia Minerals Ltd. ("
Cascadia
") (TSX-V: CAM)
(OTCQB: CAMNF) is pleased to announce the results of five additional drill holes from its fully-
funded 2026 exploration program at the road-accessible Carmacks copper-gold project in central
Yukon. These results continue to expand mineralization at Carmacks beyond the boundaries of the
existing Mineral Resource and highlight one of the highest-grade intervals ever drilled on the project.
2000S Long Section Step-out
Carmacks Drilling Highlights
Hole CD-26-056 at Zone 2000S returned:
82.69 m of 1.12% copper with 0.64 g/t gold (1.78% CuEq),
including 49.16 m of 1.63% copper with 0.95 g/t gold (2.62% CuEq);
Hole 056 was drilled
70 m northwest of hole CD-26-050, which returned 52.84 m of 1.04%
copper with 0.37 g/t gold
;
The holes in this area exhibit
higher gold to copper ratios than is typically seen in the
deposit
;
Sulphide mineralization has been encountered 300 m beyond the Mineral Resource,
doubling the strike length of Zone 2000S
, with results pending for a further six step-out
holes;
The fully-funded 2026 drill program has been
expanded from 15,000 m to 18,000 m
, to allow
for additional drilling at this northern extension of Zone 2000S; and
Three holes were recently drilled at the Zone 14 target, and drilling is now underway at the
Zone A target, 11 km north of the Carmacks Deposit.
"
The interval drilled in hole 56 is one of the strongest intersections ever returned on the property
,"
said Graham Downs, President and CEO of Cascadia.
"The discovery of this significant extension
of Zone 2000S in an area previously thought to be barren is extremely encouraging. In addition to
high-grade copper, this area is also exhibiting more gold than is typically seen elsewhere in the
deposit. Given the success of this year's drilling, we are expanding our 2026 drill program to
approximately 18,000 m, with additional follow-up holes planned in the 2000S area. We have also
recently completed regional exploration holes at Zone 14, located 500 m east of the Carmacks
Deposit, and drilling is now underway at Zone A, 11 km northwest of the Carmacks Deposit."

2026 Carmacks Drilling Summary
A total of 26 holes comprising 13,106 m have been completed out of an expanded 18,000 m drill
program. Work to-date has been focused at the 147 and 2000S zones, with prioritization of holes
testing the extension of Zone 2000S north towards Zone 147. Drilling in this area has now
encountered sulphide mineralization 300 m north of the existing Mineral Resource at Zone 2000S,
within 300 m of the southern extent of sulphide mineralization drilled in Zone 147. Three holes were
recently completed at Zone 14, located 500 m east of Zone 1213. Drilling has also commenced at
Zone A, located 11 km northwest of the main Carmacks Deposit.
Eleven holes from the ongoing 2026 drill program have been previously released. Assays from the
remaining holes are pending and will be released once they are received and compiled.

Copper equivalent calculations use metal prices of US$4.00/lb for copper, US$2,500/oz for gold, US$30/oz for
silver and US$20/lb for molybdenum. Recovery factors of 82% for copper, 70% for gold, 69% for silver and 70%
for molybdenum were used, based on recovery projections from the 2023 PEA study.
Zone 2000S Drill Results
Drilling at Zone 2000S has continued to focus on extending the zone beyond historical drilling both at
depth and to the north, towards Zone 147. At Zone 2000S, historical drilling delineated mineralization
over a strike length of 300 m and was thought to terminate to the north. It was on this basis that the
2022 Resource Estimate was calculated. Drilling in 2026 has demonstrated that this area remains
open, with Zone 2000S continuing a further 300 m towards Zone 147,
doubling the strike length
of Zone 2000S
. This area is also exhibiting higher grade mineralization, with enriched gold and
molybdenum compared to other portions of the deposit.
Hole CD-26-054 was drilled 100 m down-dip of previously reported hole CD-26-048 and below the
2022 resource model. It intersected 76.31 m of 0.48% copper with 0.23 g/t gold (0.70% copper
equivalent), including
12.56 m of 0.73% copper with 0.48 g/t gold (1.16% copper equivalent)
.
This intersection represents the deepest point ever tested in the 2000S zone, for a total vertical
extent of 467 m from surface. The zone remains fully open at depth.
Hole CD-26-056 returned
one of the highest-grade intersections ever drilled on the property
,
with
82.69 m of 1.12% copper with 0.64 g/t gold (1.78% CuEq), including 49.16 m of 1.63%
copper with 0.95 g/t gold (2.62% CuEq)
. Hole 056 was drilled 70 m northwest of previously
reported hole CD-26-050, which returned 52.84 m of 1.04% copper with 0.37 g/t gold. In addition to
strong copper grades, this hole also encountered higher gold and molybdenum grades than typically
observed elsewhere in the deposit. This area remains largely open.
Results for six additional step-out holes are pending, and this area will receive targeted follow-up
drilling this fall.
Other Drill Results
Hole CD-26-052 was drilled in the deep central portion of Zone 147, underneath hole CD-26-047,
and returned 38.32 m of 0.42% copper with 0.10 g/t gold (0.54% CuEq). Hole CD-26-055 was
drilled at the deep northern extension of Zone 147 and did not return significant mineralization. This
hole suggests that Zone 147 may be pinching out at depth in this direction. Zone 147 remains open
in multiple other directions.
Hole CD-26-053 was drilled at the Sourtoe Target, located 1 km west of Zone 147, testing an IP
geophysical anomaly coincident with surface mineralization. Hole 053 and nearby hole 051
encountered several rafts of migmatized rock with non-copper-bearing sulphides which explain the IP
geophysical anomaly but do not explain surface copper mineralization present in trenches. Further
work is warranted in this area; however additional drilling is not planned this year.

Carmacks Property Overview
Cascadia's 180 km
2
Carmacks Project is located within the Traditional Territory of the Little Salmon
Carmacks and Selkirk First Nations and is 35 km southeast of the past producing Minto Mine, which
was recently acquired by Selkirk Copper Mines Inc. The Carmacks Project is road-accessible, via a
13 km access road which extends from the government-maintained Freegold Road northwest of the
town of Carmacks in central Yukon. The project has an existing 40-person camp, numerous roads
throughout the property, and is 10 km from grid power.
The project covers a large portion of the Minto Copper Belt, a 180 km x 60 km belt of intrusion-
related copper-gold-silver deposits. This belt is situated within the Stikine Terrane, which extends
into Yukon from British Columbia, and is characterized by Late Triassic to early Jurassic volcanic-
plutonic arc complexes that are well-endowed with copper-gold-molybdenum porphyries including the
Red Chris, Schaft Creek, Kemess, KSM and Galore Creek deposits and mines.
In addition to numerous early-stage targets, the project hosts the resource-stage Carmacks
Deposit, comprising a series of 5-100 m wide 'rafts' of variably migmatized xenolithic meta-
sedimentary and meta-volcanic rocks hosted within the coarse crystalline granitoids of the Granitoid
Mountain Batholith suite. The 'rafts' generally trend NNW-SSE over 3 km of strike length and form
three distinct zones of mineralization. Sulphide mineralization is confined to the metamorphic 'rafts'
and is found as chalcopyrite-bornite foliation parallel stringers as well as net-textured clots,
interpreted as evidence for later sulphide melts. The contacts with the intrusive phases of the granite
mountain batholith are sharp and unaltered. The geology and deposit model are thought to be similar
to the nearby Minto Deposit, with past work suggesting that the system is the result of an alkalic
porphyry deposit that was metamorphosed up to the point of partial melting at depths of up to 25km,
followed by rapid uplift to near surface.
The Carmacks Deposit has 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, 3.23 g/t silver and 0.01%
molybdenum) or 1.07% copper equivalent, and an Inferred Resource containing 38 Mlbs of copper
and 13 koz of gold (2.9 Mt grading 0.60% copper, 0.16 g/t gold, 2.34 g/t silver and 0.02%
molybdenum). A 2023 preliminary economic assessment demonstrated positive economic potential,
with a $230.4 M post-tax NPV
(5%)
and 29% post-tax IRR at US$3.75/lb copper and US$1,800/oz
gold. A second case evaluated at $4.25/lb copper and $2,000/oz gold returned a $330.1 M post-tax
NPV
(5%)
and 38% after-tax IRR.
The deposit is comprised of three zones, 147, 2000S and 1213, all of which come to surface and
remain open to expansion in multiple directions. Historical drilling at the deposit focused primarily on
oxide copper mineralization, and numerous holes were ended when sulphide mineralization was
encountered. Zone 1213 in particular hosts very shallow sulphide mineralization that has seen limited
drilling.
About Cascadia
Cascadia's flagship asset is the Carmacks Project in the high-grade Minto Copper Belt in Yukon
Territory, Canada. Cascadia is also exploring the Stikine Terrane in Yukon for new gold-copper
discoveries through its Strategic Alliance with Agnico Eagle Mines Ltd. The Stikine Terrane extends
into Yukon from British Columbia's Golden Triangle and is a highly prospective target area for gold-
copper porphyry mineralization. While the expression of the Stikine Terrane in British Columbia has
been explored in detail – resulting in numerous discoveries – its expression in Yukon is comparatively
underexplored and not well understood.
QA/QC
Analytical work was completed by ALS Canada Ltd., with sample preparation in Whitehorse, Yukon
and Langley, BC, and geochemical analyses in North Vancouver, BC. Core samples were fine
crushed before a 250-gram split was pulverized to better than 85% passing 75 microns. Gold was
determined for core samples by the Au-AA23 procedure, which involves fire assay preparation using
a 30-gram charge with an atomic absorption spectroscopy finish. Multi-element data for 48 elements
was determined by the ME-MS61 procedure, which involves a four-acid digestion followed by
inductively coupled plasma-atomic emission spectroscopy ("ICP-AES") and inductively coupled
plasma-mass spectrometry. Overlimit values for copper were determined by the Cu-OG62
procedure, which involves a four-acid digestion followed by ICP-AES.
Rigorous procedures are in place regarding sample collection, chain of custody and data entry.
Certified assay standards, duplicate samples and blanks are routinely inserted into the sample
stream of diamond drill samples to ensure integrity of the assay process. All diamond drill samples
included in this news release have passed the QA/QC procedures as described above. Core was
sampled using a diamond saw, with half of each interval sent to the lab for analysis, and the other
half retained. Estimated true widths vary but are expected to be typically 60-70% of the intersected
widths.
The Mineral Resources and economic analysis disclosed here are referenced from the 2023
Carmacks Project Preliminary Economic Assessment ("
Carmacks PEA
"). Pricing for the Carmacks
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 C$1 = US$0.75. The results of the Carmacks PEA 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. For
more information on the Carmacks PEA please see the Technical Report entitled Carmacks Project
Preliminary Economic Assessment (PEA), Yukon, Canada dated March 6, 2023, authored by SGS
Canada Inc. for Granite Creek Copper Ltd. A copy of this Technical Report is available on
www.cascadiaminerals.com
and on SEDAR+ under the Granite Creek Copper Ltd. profile.
Results referenced in this release represent highlights only. Below detection values for gold, copper,
silver and molybdenum have been encountered in drilling, soil and rock samples in these target
areas. Readers are cautioned that grab samples are selective by nature and are not necessarily
representative of the grade of mineralization on the property. Copper equivalent calculations use
metal prices of US$4.00/lb for copper, US$2,500/oz for gold, US$30/oz for silver and US$20/lb for
molybdenum. Recovery factors of 82% for copper, 70% for gold, 69% for silver and 70% for
molybdenum were used, based on recovery projections from the Carmacks PEA.
