Sitka Intercepts Multiple Occurrences of Visible Gold in First Drill Holes of the Summer Season at Its RC Gold Project, Yukon

(TSXV: SIG) (FSE: 1RF) (OTCQB: SITKF) ("Sitka" or the "Company") is pleased to announce that multiple instances of visible gold have been observed in the first drill holes of the summer field season its flagship RC Gold Project located in the Tombstone Gold Belt, Yukon. Three drills are currently operating and a fourth drill rig is on site as part of a fully-funded 30,000 metre drill program planned for 2025 at RC Gold. The primary focus of this year's diamond drilling campaign will be to rapidly expand the Blackjack and Eiger gold deposits while advancing several other high-priority gold targets within the Clear Creek Intrusive Complex (see Figures 4 and 5).

• Three diamond drills currently operating and a fourth diamond drill rig on site as part of the fully funded 30,000 metre drilling campaign planned at RC Gold this year, more than doubling the amount of drilling completed by Sitka Gold since work was initiated in 2020
• Additional visible gold observed in Hole 76 after it was re-entered and extended from 810.8 m to 944.9 m, the deepest hole ever drilled at Blackjack
• Visible gold observed in all drill holes completed so far this year
• Drilling is currently focused on expanding the Blackjack and Eiger deposits and exploring the Saddle zone where a linkage between the two deposits is suggested by geological observations and the largest and strongest gold-in-soil anomaly at the RC Gold Project (see Figures 3 and 4)

Several instances of visible gold have been observed in the drill core from DDRCCC-25-076 to 080, which are the first holes to be completed this summer season, with DDRCCC-25-078 and 079 producing the first visible gold ever observed at Eiger (see Figures 1). Assays are currently pending for all drill holes in this release.

"The summer field season at RC Gold is off to a strong start, with three drill rigs already turning and a fourth rig recently mobilized to site," said Cor Coe, Director and CEO of Sitka. "The presence of visible gold in the first holes of the season, including the first-ever observations of visible gold at the Eiger deposit expansion drilling, continue to demonstrate the exceptional gold endowment within the Clear Creek Intrusive Complex. This is the first follow up drilling we have conducted at the Eiger deposit since 2021 and the observations of visible gold in these initial step out holes to the west, towards the Saddle zone and Blackjack deposit, are very encouraging.

"The fully funded, 30,000 metre drill campaign planned for this year will more than double the total drilling completed since we initiated drilling in 2020, marking a major step forward in advancing RC Gold. To date, we've successfully discovered two gold deposits and outlined multiple high-priority targets ready for drill advancement. With this year's planned drilling equivalent to the past five years combined, there will be lots to look forward to as our team pushes to build on that success with additional new discoveries and meaningful expansion of our known deposits, both of which remain open in all directions."

Blackjack Drilling

Drilling at Blackjack continues to be directed at expanding the deposit, testing both the deeper underground and the near surface potential where the deposit remains open in all directions. Drill hole DDRCCC-25-076 (azimuth of 037° and dip of -75°) was extended to a depth of 944.9 m, the longest hole completed on the property to date. Visible gold was observed at 859.2 m down the hole within quartz veining in altered metasedimentary rocks. DDRCCC-25-080 (azimuth of 040o and dip of -55o) tested shallower extensions of mineralization and encountered visible gold in several locations from approximately 107 to 220 m depth.

Eiger Drilling

Drill holes DDRCCC-25-078 (azimuth of 345o and dip of -50o) and 079 (azimuth of 345o and dip of -55o) are the first holes completed on the Eiger deposit expansion program. The Eiger deposit has not been drilled since its discovery in 2021. These first two holes were drilled to expand the deposit to the west. Hole 78 encountered strongly altered metasediments with quartz veining and visible gold before being terminated in a fault zone prior to intersecting the Eiger intrusion. Hole 79 was drilled from the same set-up at a steeper angle and successfully penetrated the fault zone which was the faulted contact with the Eiger intrusion. Visible gold was encountered in Hole 79 within sheeted quartz veining within the metasediments and the Eiger intrusion.

Saddle Drilling

Drill hole DDRCCC-25-081 (azimuth of 025o and dip of -50o) is the first drill hole collared in the Saddle zone since the most recent drilling completed in 2023 which intersected 84.0 m of 1.21 g/t gold in Hole 54 and 29.0 m of 0.68 g/t gold in Hole 53. The Saddle zone is midway between the Blackjack and Eiger deposits and is defined by the largest and highest grade gold-in-soil anomaly on the property within an extensional zone containing lamprophyre and quartz monzonite intrusives dikes and sills. Drilling in 2025 is targeted to follow-up on previous drilling and define an initial resource in this area which is within the conceptual pit limits of the Blackjack deposit and explore the linkage between the two deposits. This drill hole collared in metasediments and is planned to a depth of 350.0 m.

About the flagship RC Gold Project

The RC Gold Project consists of a 431 square kilometre contiguous district-scale land package located in the heart of Yukon's Tombstone Gold Belt. The project is located approximately 100 kilometres east of Dawson City, which has a 5,000 foot paved runway, and is accessed via a secondary gravel road from the Klondike Highway which is usable year-round and is an approximate 2 hour drive from Dawson City. It is the largest consolidated land package strategically positioned mid-way between the Eagle Gold Mine and the past producing Brewery Creek Gold Mine.

The RC Gold Project now has pit-constrained mineral resources that are contained in two zones: the Blackjack and Eiger gold deposits with 1,291,000 ounces of gold in 39,962,000 tonnes grading 1.01 g/t gold in an indicated category and 1,044,000 ounces of gold in 34,603,000 tonnes grading 0.94 g/t in an inferred category at Blackjack and 440,000 ounces of gold in 27,362,000 tonnes grading 0.50 g/t gold in an inferred category at Eiger. These resource estimate numbers are supported by the recently updated technical report for RC Gold, prepared in accordance with NI 43-101 standards, entitled "Clear Creek Property, RC Gold Project NI 43-101 Technical Report Dawson Mining District, Yukon Territory", prepared by Ronald G. Simpson, P. Geo., of GeoSim Services Inc. with an effective date of January 21, 2025. This report is available on SEDAR+ (http://www.sedarplus.ca) and on the Company's website (www.sitkagoldcorp.com).

Both of these deposits begin at surface, are potentially open pit minable and amenable to heap leaching, with initial bottle roll tests indicating that the gold is not refractory and has high gold recoveries of up to 94% with minimal NaCN consumption (see News Release July 13, 2022).

To date, 73 diamond drill holes have been drilled into this system by the Company for a total of approximately 25,851 metres. Other targets drilled to date include the Saddle, Josephine, Rhosgobel and Pukelman zones. The resource expansion drilling in 2023 at Blackjack produced results of up to 219.0 m of 1.34 g/t gold including 124.8 m of 2.01 g/t gold and 55.0 m of 3.11 g/t gold in drill hole DDRCCC-23-047 (see news release dated September 26, 2023) and in 2024 results of up to 678.1 metres of 1.04 g/t gold starting from surface in DDRCCC-24-068, Including 409.5 metres of 1.36 g/t gold, 93.0 metres of 2.57 g/t gold and 5.5 metres of 17.59 g/t gold (see news release dated October 21, 2024). Results from DDRCCC-25-075, completed during winter drilling in 2025, produced the best high-grade intercepts drilled to date at Blackjack, returning 352.8 m of 1.55 g/t gold including 108.9 m of 3.27 g/t gold and 45.0 m of 4.52 g/t gold.

A planned 30,000 metre diamond drilling program for 2025 is currently underway at RC Gold.
