Approximately 17,600 m of diamond drilling have been completed to date this year in 30 drill holes across the Blackjack and Rhosgobel deposits as part of the ongoing 60,000 m drill program planned for 2026
Vancouver, British Columbia--(Newsfile Corp. - June 23, 2026) - Sitka Gold Corp. (TSXV: SIG) (FSE: 1RF) (OTCQX: SITKF) ("Sitka" or the "Company") is pleased to announce assay results from six drill holes completed during its 2026 exploration campaign and to provide an update on the 60,000 metre diamond drilling program currently underway at its 100% owned, road accessible RC Gold Project ("RC Gold" or the "Project") in Canada's Yukon Territory. Analytical results for drill holes DDRCCC-26-122 through DDRCCC-26-127 have been received and compiled and are reported herein. These results continue to expand and infill the mineralized zone at Blackjack (see Figures 1 to 3). Highlights of the reported drill holes include DDRCCC-26-123 which returned 214.5 m of 0.97 g/t Au, including 106.9 m of 1.36 g/t Au and 2.0 m of 15.45 g/t Au, DDRCCC-26-125 which returned 94.5 m of 1.62 g/t Au including 2.0 m of 11.85 g/t Au, and a separate interval of 197.0 m of 1.06 g/t Au including 2.0 m of 9.95 g/t Au, and DDRCCC-26-126 which returned 153.1 m of 1.33 g/t Au, including 110.0 m of 1.63 g/t Au and 2.0 m of 12.35 g/t Au.
Currently, six drills are turning across the project with the goal of expanding on known gold mineralization and defining new mineralization. So far this year a total of approximately 17,600 metres have been completed in 30 drill holes at the Blackjack and Rhosgobel deposits as part of the fully-funded 60,000 metres drill program planned for 2026. Assays are pending for all remaining holes.

"These results continue to demonstrate the impressive scale, continuity and high-grade nature of the Blackjack gold deposit and further strengthen our confidence in the overall growth potential of the RC Gold Project," said Cor Coe, Director and CEO of Sitka Gold Corp. "The first holes completed this year at Blackjack have returned several broad, high-grade gold intercepts that highlight the robust nature of the mineralization and continue to expand the known limits of this wide-open deposit. Furthermore, we have now completed more than 18,000 metres of additional drilling at Blackjack since the most recent resource estimate was published in early 2025. For perspective, the current resource estimate of 1.29 million ounces of indicated gold grading 1.01 g/t gold and 1.04 million ounces of inferred gold grading 0.94 g/t gold* was based on 18,800 metres of drilling, meaning we have now effectively doubled the amount of drilling completed since that estimate was calculated. With six drills currently operating and only a portion of our fully funded 60,000 metre drill program completed, we expect a steady flow of results from Blackjack, Rhosgobel and several additional targets as we continue advancing one of Yukon's largest and fastest-growing gold systems."

The 2026 drill program continues to successfully intersect broad zones of Reduced Intrusion-Related Gold mineralization at the Blackjack and Rhosgobel deposits and continues to expand and define the known gold mineralization at each area. Visible gold* has been observed associated with the RIRGS mineralization in all but one drill hole at both targets. The program will continue to define and expand these broad zones of mineralization as well as target new zones of previously defined mineralization such as the Pukelman/Contact zones, Saddle zone and Bear Paw Breccia zone.
* 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.

About the RC Gold Project
Sitka's 100% owned, flagship RC Gold Project consists of a 447 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 one of the largest consolidated land packages strategically positioned mid-way between the Eagle Gold Mine and the past producing Brewery Creek Gold Mine.
The RC Project hosts an indicated MRE of 1,291,000 ounces of gold and an inferred MRE of 3,829,000 ounces of gold (see Table A below) hosted within three at surface, road-accessible pit constrained deposits. In addition to gold resources, the Rhosgobel deposit also hosts 2,926,000 ounces of silver and 51,345 tonnes of tungsten trioxide (see Table B below). The 60,000 metre drill program planned for 2026 is focused on expanding all three known deposits in addition to testing other high potential targets in close proximity to the current resources.

* Notes for Blackjack Resources:
Mineral resource estimate prepared by Ronald G. Simpson of GeoSim Services Inc. with an effective date of January 21, 2025.
Mineral Resources are estimated consistent with CIM Definition Standards and reported in accordance with NI 43-101.
Mineral resources are not mineral reserves and do not have demonstrated economic viability.
Mineral resources are constrained by an optimized pit shell using the following assumptions: US$2000/oz Au price; a 45° pit slope; assumed metallurgical recovery of 85%; mining costs of US$2.00 per tonne; processing costs of US$10.00 per tonne; G&A of US$4.00/t.
The base case cut-off of 0.3 g/t Au is believed to provide a reasonable margin over operating and sustaining costs for open-pit mining and processing.
Totals may not sum due to rounding.
** Notes for Rhosgobel and Eiger Resources:
Mineral resource estimate prepared by Ronald G. Simpson of GeoSim Services Inc. with an effective date of February 25, 2026
Mineral Resources are estimated consistent with CIM Definition Standards and reported in accordance with NI 43-101.
Mineral resources are not mineral reserves and do not have demonstrated economic viability.
Mineral resources are constrained by an optimized pit shell using the following assumptions: US$3000/oz Au price; a 45° pit slope; assumed metallurgical recovery of 85%; mining costs of US$2.50 per tonne; processing costs of US$14.00 per tonne; G&A of US$4.00/t.
The base case cut-off of 0.3 g/t Au is based on a gold price of US$2500/oz and believed to provide a reasonable margin over operating and sustaining costs for open-pit mining and processing
Totals may not sum due to rounding.
All of these deposits begin at surface and are potentially open pit minable. Initial bottle roll metallurgical testing confirmed the non-refractory characteristics of the gold mineralization and returned gold extraction rates averaging around 85% for the Blackjack and Eiger deposits. Further metallurgical testwork in 2024 for Blackjack and Eiger returned recoveries ranging from 77.6 to 93% for gravity followed by cyanidation. Initial bottle roll testing for Rhosgobel has confirmed non-refractory characteristics of the gold mineralization with two composite samples returning gold recoveries of 89% and 96%. Additional metallurgical testing at Rhosgobel has returned an average gold recovery of 94.3% using conventional whole ore cyanidation leaching and an initial recovery of 84.7% tungsten in rougher concentrate using conventional floatation. Metallurgical testing for potential silver recovery has not yet been completed.

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 atomic emission 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). Select intervals at the Rhosgobel Deposit were selected for additional XRF analysis on a lithium borate fusion (ALS code: XRF-15b) for WO3.
