Vancouver, British Columbia--(Newsfile Corp. - September 8, 2025) - Sitka Gold Corp. (TSXV: SIG) (FSE: 1RF) (OTCQB: SITKF) ("Sitka" or the "Company") is pleased to announce additional positive assay results from the Rhosgobel discovery at its 100% owned, road accessible RC Gold Project ("RC Gold" or the "Project") located in the Yukon's prolific Tombstone Gold Belt. The mineralized footprint of the Rhosgobel discovery continues to expand along strike with visible gold observed in 31 of 34 holes logged to date over a strike length of approximately 1.1 km within the 2.0 km x 1.5 km target (see Figures 2 and 3). A total of 30,478 metres of drilling have been completed this year across a 7 kilometre stretch within the Clear Creek Intrusion Complex at the Blackjack, Saddle, Eiger, Pukelman, Contact, Rhosgobel and Bear Paw areas (see Figure 7). Two drills are currently operating at RC Gold with assays pending for 50 holes, including 26 holes from Rhosgobel.

"The consistency and scale of strong assay results from Rhosgobel are very encouraging, with every drill hole reported to date delivering over 100 gram-metres of gold," said Cor Coe, Director and CEO of Sitka Gold. "While this inaugural drill program has only tested the core target area of the intrusion it has already outlined a gold system that has been traced for over a kilometre along strike, beginning at surface and extending to depths that exceed 400 metres. With mineralization open in all directions within the 2.0 by 1.5 kilometre gold-in-soil anomaly that outlines this target, Rhosgobel is demonstrating the size and grade potential to host a significant, multi-million ounce intrusion related gold deposit. These results, along with over 30,000 metres of successful drilling that has been completed this year across the Clear Creek Intrusive Complex and the strong pipeline of additional targets and grassroots opportunities across this district-scale land package, reinforce the potential of the RC Gold Project to evolve into a major new gold camp in the Yukon."

RHOSGOBEL DRILLING
To date, 38 holes totalling approximately 11,375 m have been completed at Rhosgobel. 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 approximately 1.1 kilometres within a large 2.0 km x 1.5 km surface signature represented by a gold-in-soil anomaly with values up to >500 ppb (Figure 3). Gold mineralization at Rhosgobel begins at surface, extends to a depth of over 400 metres and remains open in all directions. The first eight diamond drill holes, including the two discovery holes drilled in 2024, have all intersected >100 gram-metres gold (g/t Au*m).
* 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/4YeeNC0An2) and on the Company's website ( www.sitkagoldcorp.com).
Both of these deposits begin at surface, are potentially open pit minable and Initial bottle roll metallurgical testing confirmed the non-refractory characteristics of the gold mineralization and returned gold extraction rates averaging around 85%. Further metallurgical testwork in 2024 returned recoveries ranging from 77.6 to 93% for gravity followed by cyanidation.
For the purposes of the current resource model, it is assumed that a likely mill flowsheet would consist of a gravimetric, flotation, and cyanidation circuit.
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.
