Vancouver, British Columbia--(Newsfile Corp. - August 5, 2025) - Sitka Gold Corp. (TSXV: SIG) (FSE: 1RF) (OTCQB: SITKF) ("Sitka" or the "Company") is pleased to announce positive assay results from its fully funded 30,000 metre diamond drill program currently underway at its 100% owned, road accessible RC Gold Project located in the Yukon's prolific Tombstone Gold Belt. Results received and compiled for holes DDRCRG-25-003 (hole 003) and DDRCRG-25-005 (hole 005), which were prioritized at the lab and drilled at the Rhosgobel intrusion target, located approximately 5 kilometres south of the Blackjack gold deposit (see Figure 7), have returned strong gold values from surface and confirm the presence of a newly discovered intrusion-related gold deposit at Rhosgobel, the 3rd gold deposit discovered to date at RC Gold. Results from initial 2025 drilling have intersected up to 152.1 metres of 1.00 g/t gold from surface, including 9.0 metres of 4.23 g/t gold and 10.0 metres of 2.75 g/t gold, in DDRCRG-25-003 and 114.8 m of 1.11 g/t Au from surface, including 8.6 m of 3.50 g/t Au, in DDRCRG-25-005 (see Tables 1 and 2). Holes 003 and 005 were collared approximately 50 and 100 metres along strike respectively from discovery holes 001 and 002 which were completed last year (see Figure 3). These are the first results to be received this year for drilling that is currently underway at Rhosgobel, where two drill rigs are operating and up to 10,000 metres of drilling is planned to be completed this year. To date, 18 holes have been completed at Rhosgobel this year with assays currently pending for 14 holes. Over 21,000 metres of the 30,000 metre drill program planned at the RC Gold project have been completed so far this year with assays currently pending for 43 holes drilled at the Blackjack-Saddle-Eiger zone and the Rhosgobel and Pukelman targets. Drilling has also recently commenced at the Pukelman intrusion, located approximately 2.5 km southeast of the Blackjack deposit. Two drills are currently turning at Pukelman where historical data, including 10.7 metres of 20.46 g/t gold intersected in previous drilling (see news release dated June 24, 2024), suggests the potential of another reduced intrusion-related gold deposit. Up to 5,000 metres of diamond drilling is planned to be completed at Pukelman this year.

"The strong gold results from initial drilling at Rhosgobel this summer are highly encouraging and further confirm both the scale and strength of gold mineralization that is present across what appears to be a very well-endowed gold system within the Clear Creek Intrusive Complex," said Cor Coe, CEO and Director of Sitka Gold. "Results such as those seen in DDRCRG-25-003 suggest that the Rhosgobel intrusion target hosts gold grades comparable to those seen at the Blackjack gold deposit located 5 kilometres to the north. In addition, every hole that has been reported to date from Rhosgobel, which includes the discovery holes 001 and 002 from last year and the holes in this release, has returned intervals that exceed 100 gram-metres (grams per tonne*meters) of gold, confirming that another intrusion-related gold deposit has been discovered. With visible gold observed in the majority of the drill holes completed at Rhosgobel, gold mineralization starting at surface, and a broad gold-in-soil anomaly measuring approximately 2.0 km by 1.5 km, the potential scale of mineralization at this target is quite large."

RHOSGOBEL TARGET DRILLING
To date, 18 holes totalling approximately 4,593 m have been completed at the Rhosgobel target. All holes drilled have intersected significant reduced intrusion-related gold (RIRGS) style mineralization including centimetre-scale, sheeted, quartz veins and larger, metre-scale quartz, and quartz-tourmaline veins (and breccias) cutting the feldspar megacrystic quartz monzonite intrusion. Visible gold has been observed within all styles of veins and is often associated with bismuthinite, scheelite, and molybdenite (see Figure 4). Drilling to date has traced mineralization over a strike length of 900 metres and from surface to a depth of 450 metres within a large 2.0 km x 1.5 km surface signature represented by a gold-in-soil anomaly with values up to >500ppb (Figure 3). The mineralization at Rhosgobel remains open in all directions. The first four diamond drill holes, including the two discovery holes drilled in 2024, have all intersected >100 gram-metres (g/t*m) of gold.
Drill holes DDRCRG-25-003 and DDRCRG-25-004 (holes 003 and 004) were drilled from the same pad located approximately 100 m east-southeast of drill holes DDRCRG-24-001 (119.0 metres of 1.05 g/t gold from 30 m, see Company press release dated November 25, 2024, and 002 (28.4 m of 1.37 g/t Au from 105 m, same release). Both holes intersected megacrystic quartz monzonite (MCQM) similar to holes 001 and 002 and both intersected broad intervals of abundant 1-2 cm sheeted quartz veins, larger (10-40 cm) quartz tourmaline veins, and large zones of quartz tourmaline breccias and stockwork. Visible gold was observed in both holes within the quartz veins and breccias and was consistently associated with bismuthinite, coarse crystalline scheelite, and occasionally molybdenite.
Hole DDRCRG-25-003 intersected significant gold mineralization from surface (see Tables 1 and 2) returning 152.1 m of 1.00 g/t Au from 3.1 m, including 9.0 m of 4.23 g/t Au from 89.0 m and 10.0 m of 2.75 g/t Au from 113.0 m. Assay results for hole DDRCRG-25-004 are pending.
Drill holes DDRCRG-25-005 and DDRCRG-25-006, (holes 005 and 006) were drilled from the same pad approximately 80 m north-east of drill holes DDRCRG-24-001 (119.0 metres of 1.05 g/t gold from 30 m, see Company press release dated November 25, 2024, and 002 (28.4 m of 1.37 g/t Au from 105 m, same release). Both holes intersected megacrystic quartz monzonite (MCQM) similar to holes 001 and 002 and both intersected broad intervals of abundant 1-2 cm sheeted quartz veins, larger (10-40 cm) quartz tourmaline veins, and large zones of quartz tourmaline breccias and stockwork. Visible gold was observed in both holes within the quartz veins and breccias and was consistently associated with bismuthinite, coarse crystalline scheelite, and occasionally molybdenite.
Hole DDRCRG-25-005 intersected significant gold mineralization from surface (see Tables 1 and 2) returning 114.8 m of 1.11 g/t Au from 4.18 m, including 14.9 m of 3.28 g/t Au from 4.18 and 8.6 m of 3.50 g/t Au from 41.0 m. Assay results from hole DDRCRG-25-006 are pending.
Drill hole DDRCRG-25-011 (hole 011) was drilled on the same section as hole 005/006 approximately 100 southeast from the collar of 005/006. This hole intersected megacrystic quartz monzonite (MCQM) similar to holes 005 and 006 and also intersected broad intervals of abundant 1-2 cm sheeted quartz veins, larger (10-40 cm) quartz tourmaline veins, and large zones of quartz tourmaline breccias and stockwork similar to 005/006. Visible gold was observed within the quartz veins and breccias and was consistently associated with bismuthinite, coarse crystalline scheelite, and occasionally molybdenite. Assay results from hole DDRCRG-25-011 are pending.
PUKELMAN TARGET DRILLING
Drilling has recently commenced at the Contact-Pukelman target area where historical drilling intersection up to 10.7 metres of 20.46 g/t gold (CC10-22), 38.3 metres of 1.54 g/t gold (CC11-043) and 74.3 metres of 1.01 g/t gold (CC11-044; see Figure 7; see news release dated June 24, 2024). Structural features suggest strong reduced intrusion-related gold style mineralization is associated with a structural corridor and a quartz-feldspar porphyritic felsic dyke at the contact zone. Initial work completed by the Company in 2024 at the Pukelman target returned surface grab samples of up to 67.9 g/t gold and demonstrated that broad zones of reduced-intrusion related gold style mineralization exists within the intrusion (see news release dated October 31, 2024).
* While visible gold observations are very encouraging and confirm the presence of gold mineralization, they are not intended to imply potential gold grades. Gold assays will be published after they are received from the lab for mineralized intervals in which visible gold particles were noted.

Quality Assurance/Quality Control
On receipt from the drill site, the HTW/NTW-sized drill core was systematically logged for geological attributes, photographed and sampled at Sitka's core logging facility. Sample lengths as small as 0.3 m were used to isolate features of interest, otherwise a default 2 m downhole sample length was used. Each sample is identified by a unique sample tag number which is placed in the bag containing the core to be assayed. Core was cut in half lengthwise along a predetermined line, with one-half (same half, consistently) collected for analysis and one-half stored as a record. Standard reference materials, blanks and duplicate samples were inserted by Sitka personnel at regular intervals into the sample stream. Bagged samples were placed in secure bins to ensure integrity during transport. They were delivered by Sitka personnel or a contract expeditor to ALS Laboratories' preparatory facility in Whitehorse, Yukon, with analyses completed in North Vancouver.
ALS is accredited to ISO 17025:2005 UKAS ref. 4028 for its laboratory analysis. Samples were crushed by ALS to over 70 per cent passing below two millimetres and split using a riffle splitter. One-thousand-gram splits were pulverized to over 85 per cent passing below 75 microns. Gold determinations are by fire assay with an inductively coupled plasma mass spectroscopy (ICP-AES) finish on 50 g subsamples of the prepared pulp (ALS code: Au-ICP-22). Any sample returning over 10 g/t gold was re-analyzed by fire assay with a gravimetric finish on a 50 g subsample (ALS code: Au-GRA21). In addition, a 51-element analysis was performed on a 0.5 g subsample of the prepared pulps by an aqua regia digestion followed by an inductively coupled plasma mass spectroscopy (ICP-MS) finish (ALS code: ME-MS41).
About Sitka's Flagship RC Gold Project
Sitka's 100% owned 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+ (https://api.newsfilecorp.com/redirect/jNpwWHLVyK) 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).
As of the end of 2024, the Company has drilled 72 diamond drill holes into this system for a total of approximately 25,136 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 metres of 1.34 g/t gold including 124.8 metres of 2.01 g/t gold and 55.0 metres 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 metres of 1.55 g/t gold including 108.9 metres of 3.27 g/t gold and 45.0 metres of 4.52 g/t gold (see news release dated April 22, 2025).
A planned 30,000 metre diamond drilling program for 2025 is currently underway at RC Gold.
