VANCOUVER, CANADA – June 11, 2025: Sitka Gold Corp. (“Sitka” or the “Company”)
(TSX-V:SIG) (FSE:1RF) (OTCQB:SITKF) is pleased to announce initial assay results from its
2025 summer drill program currently underway at its 100% owned RC Gold Project located in
Yukon’s prolific Tombstone Gold Belt (see Figure 6). Results received from the extension of
DDRCCC-25-076, which was initially completed to a depth of 810.8 metres during winter drilling
earlier this year (see news release dated May 8, 2025) and subsequen tly extended to 944.9
metres, returned 65.0 m of 2.00 g/t gold from 806.0 metres, which includes two higher grade
intervals of 8.0 m of 4.80 g/t gold and 6.26 m of 5.53 g/t gold (see Table 1). The Company is
also pleased to announce that a fourth drill rig is being mobilized to the Rhosgobel intrusion target
where up to 10,000 metres of drilling is proposed to build upon the discovery hole from last year
that returned 164.8 metres of 0.82 g/t gold starting 9 metres from surface, including 119.0
metres of 1.05 g/t gold, 37.9 metres of 2.05 g/t gold and 11.5 metres of 4. 32 g/t gold (see
news release dated November 25, 2025). In addition, the Company is pleased to announce that
visible gold has been observed for the first time ever in drill core from the Saddle zone. Three drill
rigs are currently turning at the Blackjack, Saddle and Eiger zones (see Figure 6) as part of a fully
funded, 30,000 metre drill campaign planned for 2025, with a total of over 6,127 metres within 17
drill holes co mpleted so far this year. Assays are currently pen ding for DDRCCC -25-077 to
DDRCCC-25-091.
“Our decision to re -enter and deepen Hole 76 has yielded some impressive results,” said Cor
Coe, Director and CEO of Sitka. “As the deepest hole drilled to date, Hole 76 adds to the growing
evidence of a potential underground component to the Blackjack gold deposit and demonstrates
that intervals of significant gold values persist almost a kilometre deep from where this deposi t
begins at surface. The higher-grade gold seen at depth in this and other deep drill holes, supports
the notion that we could be vectoring towards the potential source of this gold system.
“We are also very excited to be mobilizing our fourth drill rig to the Rhosgobel intrusion where the
first two diamond drill holes ever drilled, completed by Sitka last year, resulted in two new
discovery holes that returned significant gold intervals starting 9 metres from surface. This target
sits within a large 1.5 x 2.0 kilometre gold -in-soil anomaly with historical shallow drill results
showcasing significant gold values. Sitka’s discovery holes demonstrate that gold mineralization
continues to at least 300 metres, suggesting the possibility of a large gold deposit being present
in the area.
“Lastly, we are happy to announce the first ever observations of visible gold at the Saddle zone,
where drilling is currently ongoing as we investigate the potential of the Saddle zone to link the
Blackjack and Eiger gold deposits. We have now confirmed th at visible gold is present at the
Blackjack, Saddle, Eiger, Josephine, Pukleman and Rhosgobel targets which are all located
within the 5 x 12 kms Clear Creek Intrusive Complex area. With up to 10,000 metres of drilling
about to begin at Rhosgobel, 5,000 metres of drilling allocated for Pukelman and 15,000 metres
of drilling currently underway at the Blackjack-Saddle-Eiger corridor, we are looking forward to a
steady flow of results as we further ramp up our fully funded 30,000 metre drill program at RC
Gold.”

the hole at 944.9 metres with 4.9 metres of 0.95 g/t gold reported in metasediments located
in the footwall of the lamprophyre dyke.

BLACKJACK DRILLING
Drill hole DDRCCC-25-076 was drilled to a depth of 810.8 metres during winter drilling to test the
deep underground potential of the Blackjack deposit. Winter results from Hole 76 returned 94.0
m of 1.15 g/t gold including 12.2 m of 4.55 g/t gold, and a separate interval of 25.0 m of 5.04
g/t gold, including 1.8 metres of 54.70 g/t gold within 86.4 m of 1.65 g/t gold (see news release
dated May 8, 2025). Hole 076 was subsequently extended from 810.8 metres to a depth of 944.9
metres at the start of the summer drilling campaign, to follow up on gold mineralization identified
at the bottom of the hole during the winter program. The extended drilling intercepted several
examples of visible gold hosted within sheeted quartz veins cutting altered biotite schists and
feldspar megacrystic quartz monzonite and returned 65.0 m of 2.00 g/t gold from 806.0 metres,
which includes two higher grade intervals of 8.0 m of 4.80 g/t gold and 6.26 m of 5.53 g/t gold
(see Table 2). The higher grade gold intersections were hosted within metasediments and
intrusive rocks respectively. Gold mineralization was intersected at the end of the hole with 4.9
metres of 0.95 g/t gold from 940.0 metres to 944.9 metres in the footw all metasediments after
cutting the lamprophyre dyke, demonstrating the mineralized conduit feeding this gold system
continues to depth.
RHOSGOBEL DRILLING
Sitka is pleased to initiate the first large scale diamond drilling of the Rhosgobel intrusion with
10,000 metres of drilling planned on the target. D iscovery hole DDRCRG -24-001, the first
diamond drill hole ever completed on the Rhosgobel intrusion, returned 164.8 metres of 0.82 g/t
gold starting 9 metres from surface, including 119.0 metres of 1.05 g/t gold, 37.9 metres of
2.05 g/t gold and 11.5 metres of 4.32 g/t gold (see Figure 4).
The Rhosgobel intrusion is the largest and southernmost exposed intrusion that forms a part of
the Clear Creek Intrusive Complex (the “CCIC”; see Figure 6). The Rhosgobel intrusion is a
megacrystic quartz monzonite (MCQM) similar to the Saddle Intrusion th at hosts the Blackjack
Deposit 5 km to the north.
Previous shallow reverse circulation drilling completed in 1995 identified widespread gold
mineralization within a 1.5 by 2.0 kilometre gold -in-soil anomaly within the Rhosgobel intrusion
demonstrating the potential of the intrusion to host a near surface gold deposit. No further work
was completed on the Rhosgobel intrusion until 2024 when the Sitka completed the first two
diamond drill holes ever drilled on the target.
SADDLE ZONE DRILLING
Current drilling has identified the first instance of visible gold at the Saddle Zone in Hole DDRCCC-
25-086 (“Hole 86”). The Saddle zone is located midway between the Blackjack and Eiger deposits
and is partially within the conceptual pit limit of the Blac kjack resource. Drilling at Saddle will
expand on previous drill intercepts including 84.0 m of 1.21 g/t gold in DDRCCC-25-054. Hole
86 was drilled at an azimuth of 210 o and dip of -50o to a final length of 126.5 metres to test the
shallow potential of gold mineralization in this area (see Figure 2). The drill hole intercepted broad
areas of hornfels metasediments interlaced with quartz veining, quartz monzonite dykes/sills as
well as some minor faults and breccia zones. Several instances of visible gold we re noted
throughout the hole, in quartz veins in metasedimentary rock (see Figure 5).
Figure 3: Shallow historical reverse-circulation drilling in the Rhosgobel intrusion in 1995
demonstrated significant gold mineralization occurred within a 1.5 by 2.0 km gold in soil
anomaly The first ever diamond drill holes completed at Rhosgobel in 2024 (DDRCRG-24-
001 and 002) further highlight the potential for this gold system to continue to a depth of
at least 300 metres.
