SITKA DEEPENS WINTER DRILL HOLE AND

INTERSECTS 65.0 METRES OF 2.00 G/T GOLD,

INCLUDING 6.3 METRES OF 5.53 G/T GOLD;

MOBILIZES FOURTH DRILL RIG TO THE RHOSGOBEL

TARGET AT ITS RC GOLD PROJECT, YUKON

● Extension of DDRCCC-25-076 confirms significant gold mineralization continues for over

one kilometre from surface at the Blackjack deposit and confirms the potential for an

underground mining component to the deposit

● Fourth drill rig mobilizing to the Rhosgobel target where up to 10,000 m of drilling is

planned to follow up on discovery drill holes announce last fall

● First ever visible gold observed in drill core from the Saddle zone where drilling is currently

testing a possible linkage between the Blackjack and Eiger gold deposits

● 30,000 metre drill program rapidly advancing with 17 holes totalling approximately 6,127

metres completed to date within the Blackjack-Saddle-Eiger area

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.
