SITKA COMMENCES THE FIRST DRILL PROGRAM
EVER TO BE CONDUCTED AT ITS COPPERMINE
RIVER PROJECT IN NUNAVUT WHERE UP TO 41.54%
COPPER AND 13.45% COPPER HAVE BEEN
IDENTIFIED IN VOLCANIC-HOSTED AND
SEDIMENT-HOSTED TARGET AREAS
● Drilling to target a new sediment-hosted copper discovery at the Copper Leaf showing
where surface grab samples have returned copper and silver assays as high as 13.45%
Cu and 65.0 g/t Ag; two separate geophysical surveys completed to date show an open
gravity anomaly below the grab sample area, with a current strike length of over 400
metres
● Drilling is also planned to test volcanic-hosted high-grade copper targets at the WIN
showing, located approximately 55 kms NE of the Copperleaf showing, where surface
grab samples returned up to 41.54% Cu and 36.0 g/t Ag.
● Target areas are located ~30 km and ~60 km from the commercial airstrip in Kugluktuk
and nearby tide waters which offer alternative commercial transport options as the
Northwest Passage has recently become a viable shipping route.
● The Coppermine River Project is 100% owned by Sitka through its wholly owned
subsidiary Arctic Copper Corp.
VANCOUVER, CANADA – July 8, 2025: Sitka Gold Corp. (“Sitka” or the “Company”)
(TSX-V:SIG) (FSE:1RF) (OTCQB:SITKF) is pleased to announce that it has commenced
diamond drilling at its 100% owned Coppermine River Project (“Coppermine” or the “Project”)
located near the town of Kugluktuk, Nunavut. This is the first drilling campaign of any type ever
to be conducted at the Project. Azrock Drilling Corp., a highly experienced Canadian drilling
contractor with a reputation for delivering efficient, quality production in Canada’s remote north,
has been contracted to complete up to 1,000 metres of diamond drilling as a first phase of drill
testing at Coppermine. The focus of drilling will be to test two high priority copper targets, the
Copper Leaf and the WIN showings (see Figures 1 to 3), which were previously defined by the
Company during initial mapping, surface sampling and geophysical surveys that were
conducted between 2015 and 2019. Results of up to 13.45% copper and 65.0 g/t silver were
returned from surface grab samples at Copper Leaf during this time while up to 41.54% copper
and 36.0 g/t silver were returned in surface sampling at WIN*(1).
*Grab samples referred to in this news release are, by their nature, selected samples and the results may not be representative of
the overall occurrence.
Figure 1: Examples of surface rocks at the Copperleaf and WIN targets. Massive stratiform
chalcocite in Husky Creek Sandstone is displayed at the Copperleaf showing where a grab
sample from this material assayed 13.45% Cu and 11.0 g/t Ag. Massive chalcocite and
malachite is displayed at the WIN showing where grab sample R442005 assayed 40% Cu and
36.0 g/t Ag(1).
“We are very excited to have the first drill program ever to be conducted underway at our
Coppermine River project where our previous work, including surface sampling and gravity
geophysics, has outlined some very promising drill targets,” said Cor Coe, Director and CEO of
Sitka Gold. “Reconnaissance work previously completed by Sitka produced some impressive
results, with up to 41.54% copper and 36.0 g/t silver returned from surface samples at the
high-grade, volcanic-hosted WIN copper target and up to 13.45% copper and 65.0 g/t silver
discovered in surface grab samples at the Copper Leaf sediment-hosted copper target. The
Coppermine River area is known to be a well endowed, mineral rich jurisdiction, however it
wasn’t until just recently that shipping routes through the Northwest Passage opened up, which
now provide a viable means to get these minerals to market. While the Company’s main focus
and priority continues to be advancing its flagship RC Gold project, where four drills are
currently turning as part of a planned 30,000 metre diamond drilling program for 2025, the
potential for the discovery of a significant, high-grade copper deposit at Coppermine is very
compelling and we eagerly await the initial results of this first pass of drilling.”
Copper Leaf Target
The Copper Leaf showing is a new stratiform sediment-hosted copper discovery made by
Sitka’s field team during initial reconnaissance prospecting in the area. Located approximately
60 km southwest of Kugluktuk, the Copper Leaf showing is comprised of disseminated plus
massive chalcocite and malachite mineralization within the Husky Creek sandstones with
mineralization appearing to lie proximal to a major gabbro dyke that trends north-south for more
than 12 km (see Figure 2). Grab samples were taken from several mineralized occurrences
within the sandstone unit while prospecting the Gabbro-Sediment contact along a 2 km stretch
extending southward from the Copper Leaf showing with copper and silver assays from these
samples returning up to 13.45% copper and up to 65.0 g/t silver (see Figure 1). Gravity
surveys conducted by Sitka over the Copper Leaf showing revealed a strong gravity anomaly
approximately 90 metres wide located proximal to the Gabbro Dyke and follow-up gravity
surveys in the surrounding area suggest significant strike potential along the east flank of the
Gabbro Dyke for more than 400 metres. This bodes well for the discovery of large
sediment-hosted copper deposits in this area given that this dyke-sediment contact extends for
more than 12 km through the Company’s mining claims (see Figure 2).
Examples of stratiform sediment-hosted copper deposits with similar mineral occurrences to
Copper Leaf include the Kamoa-Kakula Copper Complex located in the Democratic Republic of
Congo with a combined indicated mineral resource of 1.4 billion tonnes grading 2.74% copper,
containing 83.7 billion pounds of copper and a combined Inferred Mineral Resource of 339.0
million tonnes grading 1.68% copper, containing 12.5 billion pounds of copper(2) and the
Fore-Sudetic Monocline in Poland with anticipated mineral resources pop of 3.542 billion tons
yielding 125.5 billion pounds of copper and 5.8 billion ounces of silver(3).

areas. Up to 1000 metres of diamond drilling is proposed to test these targets in what will be the
first drilling campaign ever conducted on the Project.

WIN Target
The WIN and HA showings are located approximately 30 km southeast of Kugluktuk and some
55 km northeast of the Copper Leaf showing. Several mineral occurrences are present in the
area, ranging from disseminated copper sulphides within the lower Rae Group sediments to
high grade fracture fill lodes within basalt flows of the underlying Copper Creek formation.
Seven samples taken by Sitka personnel of massive chalcocite mineralization with the basalt
flows from historic test pits at the WIN showing returned results ranging from 0.05% copper to
41.54% copper (see Figure 4). Three samples of similar basalt hosted chalcocite mineralization
from historic trenches at the HA showing returned values ranging from 1.45% copper to 17.55%
copper.
Examples of volcanic-hosted copper deposits with similar mineralization include the Keewena
Peninsula in the U.S.A. with 387.5 million tons grading 2% copper for a total of 15.5 billion
pounds of copper(4) and Mt. Isa Provence in Australia with 280.3 million tons grading 3.3%
copper for a total of 18.5 billion pounds of copper(5).

ABOUT THE COPPERMINE RIVER PROJECT
Sitka Gold, through its wholly owned subsidiary Arctic Copper Corp., holds 12,048 hectares
(29,758 acres) of mining claims in two separate claim blocks (Figure 1) in the Coppermine River
area in Nunavut that exhibit exceptional potential to host economic grades of copper and silver
mineralization. The project has both sediment-hosted and volcanic-hosted copper targets.
After staking the project in 2015, a first phase exploration program was completed that
consisted of prospecting, geological mapping and a single line gravity geophysical ground
survey. Prospecting during the exploration program culminated in the discovery of a new
sediment-hosted copper showing (the ‘Copper Leaf’ showing) and a coincident gravity anomaly
over the mineralized area. The Copper Leaf showing consists of disseminated plus massive
chalcocite and malachite mineralization within the Husky Creek sandstones. The mineralization
appears to lie proximal to a major gabbro dyke that trends north-south for more than 12 km.
Grab samples were taken from several mineralized occurrences within the sandstone unit while
prospecting the Gabbro-Sediment contact along a 2km stretch extending southward from the
Copper Leaf showing. Copper and silver assays from these samples returned values as high as
13.45% Cu and 65.0 g/t Ag. The single line gravity survey (see Figure 3) that was conducted
over the Copper Leaf showing in 2015 revealed a strong gravity anomaly 90 m wide located
proximal to the Gabbro Dyke and extending to the east. An expanded gravity survey conducted
in 2019 suggested significant strike potential along the east flank of the Gabbro Dyke for more
than 400 m. This bodes well for the discovery of large sediment-hosted copper deposits in this
area, given that this dyke-sediment contact extends for more than 12 km through the
Company’s mining claims. The Company is in receipt of a technical report(4) by Scott Close,
P.Geo., dated Dec. 15, 2015 on its Coppermine River Project that includes the most recent
results of the 2015 exploration program.
The mineral occurrences at Copper Leaf display similarities to other major world renowned
sediment hosted copper deposits such as the Kamoa-Kakula copper deposits in the Democratic
Republic of Congo (DRC). The similar stratiform style, similar age, and similar depositional and
tectonic environment indicate the potential for large high-grade copper deposits to occur at
Copper Leaf. The current published mineral resource at Kamoa-Kikula has a combined
Indicated Mineral Resource of 1.4 billion tonnes grading 2.74% copper, containing 83.7 billion
pounds of copper and a combined Inferred Mineral Resource of 339.0 million tonnes grading
1.68% copper, containing 12.5 billion pounds of copper(2).
*The disclosures above are strictly for deposit model comparisons and the mineralization hosted on these
properties is not necessarily indicative of mineralization hosted on the Company’s property.
