Step out drilling at Eiger continues to return broad intervals of significant gold mineralization beyond the current Mineral Resource Estimate ("MRE") boundary at the Eiger deposit, which remains open in all directions
Drill hole DDRCCC-25-109 intersected 121.0 m of 0.75 g/t Au and 26.0 m of 1.28 g/t Au within 249.9 m of 0.58 g/t Au, further expanding the Eiger Deposit
Recent results suggest a higher-grade component to the Eiger deposit is emerging at depth which is a characteristic of the more advanced Blackjack deposit located approximately 1.5 km to the west
Drilling continues to define a robust gold system within the Blackjack - Saddle - Eiger extensional corridor where recently released assay results returned 44.4 m of 1.33 g/t Au at the Saddle target, approximately 1,000 m to the west of Eiger
Additional results pending for 38 drill holes, including 26 holes from the new Rhosgobel discovery and the remainder from Pukelman, Contact, Bearpaw, and May-Qu.
Vancouver, British Columbia--(Newsfile Corp. - December 2, 2025) - Sitka Gold Corp. (TSXV: SIG) (FSE: 1RF) (OTCQB: SITKF) ("Sitka" or the "Company") is pleased to announce additional analytical results from drilling completed at its

"Drilling continues to outline a large, robust gold system at Eiger, which remains open in all directions, while expanding the mineralized footprint beyond the current deposit model," stated Cor Coe, CEO and Director of Sitka Gold. "This year marked the first follow up drilling completed at Eiger since the initial MRE, based on just 13 drill holes, was published in 2021. Strong gold intercepts such as the 121.0 metres of 0.75 g/t gold and 26.0 metres of 1.28 g/t gold within 249.9 metres of 0.58 g/t gold in hole 109, which included, which was intercepted 325 metres beyond the current MRE boundary, underscore the potential to add significant ounces to the Eiger deposit where a higher-grade component appears to be developing. As additional drilling is completed, our understanding of the controls of mineralization at Eiger continue to evolve in a similar way as it did at the neighbouring Blackjack deposit where much more drilling has delineated a substantial, higher-grade resource. There is still plenty of untapped potential at Eiger and we anticipate ramping up drilling efforts there as part of next year's expanded exploration program with up to 60,000 metres of drilling planned."
"Eiger is just one of multiple intrusion-related gold deposit targets within the broader Clear Creek Intrusive Complex where the robust scale and continuity of gold mineralization across this district-scale land package is becoming increasingly evident. As assays continue to be received, we look forward to releasing additional pending results from the many other target areas that were drilled at RC Gold this year, including Pukelman, Contact, Rhosgobel, Bearpaw and May-Qu."

Eiger Deposit
Drilling at the Eiger in 2025, which included 10 holes for 4,401 meters, was successful in extending the known mineralization at the Eiger deposit. Drilling intersected reduced intrusion-related gold style mineralization including centimetre scale quartz veins with visible gold often associated with bismuthinite, arsenopyrite, and occasionally scheelite and extended mineralization to the east, west, and down dip. The current mineral resource estimation at Eiger is 440,000 ounces of gold in 27,362,000 tonnes grading 0.50 g/t gold in an inferred category. Recently completed drilling at Eiger, including the 121.0 m of 0.75 g/t Au from 248.0 m and 26.0 m of 1.28 g/t Au from 325.0 m intercepted in DDRCCC-25-109, suggest a higher-grade component to the deposit could be emerging at depth, which is a characteristic of the more advanced Blackjack deposit located 1.5 km to the west. The Eiger deposit remains open in all directions.
Previous mapping by US Geological Survey and the Yukon Geological Survey (Marsh et al, 1998, Marsh et al, 1999) has demonstrated that the gold mineralization identified at the Blackjack Deposit, the Saddle Zone and the Blackjack deposit occurs within a 1 km by > 4 km extensional corridor (Figure 4). Such corridors can create structural conditions favourable for the emplacement of intrusive rocks and associated gold mineralization.
* 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
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 Initial bottle roll metallurgical testing confirmed the non-refractory characteristics of the gold mineralization and returned gold extraction rates averaging around
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.
The company has now completed 165 diamond drill holes for a total of 59,770 metres across the Clear Creek Intrusive Complex (CCIC), and an additional 3 holes for 858 metres in the May-Qu Intrusion. Drilling continues to outline higher grade mineralization at all zones including hole DDRCCC-24-068 at Blackjack which intersected 678.1 metres of 1.04 g/t gold starting from surface (see news release dated October 21, 2024), and hole DDRCCC-25-075 which intersected 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). Drilling in 2024/2025 has resulted in the discovery of a new higher grade zone at Rhosggobel including hole DDRCRG-25-010 at Rhosgobel which intersected 235.9 metres of 1.11 g/t gold, including 40.0 m of 2.01 g/t gold and 10.0 m of 5.29 g/t gold, from surface (see news release dated September 18, 2025).
