Sitka Files Technical Report

Vancouver, British Columbia–(Newsfile Corp. – July 10, 2026) – Sitka Gold Corp. (TSXV: SIG) (FSE: 1RF) (OTCQX: SITKF) (“Sitka” or the “Company”) announces that it has filed a technical report on its 100% owned RC Gold Project in the Yukon Territory. The technical report, titled “RC Gold Project, NI 43-101 Technical Report, Dawson Mining District, Yukon Territory” is dated July 10, 2026 and has an effective date of February 25, 2026. The technical report is available on SEDAR+ (www.sedarplus.ca) and on the Company’s website at www.sitkagoldcorp.com.

Mineral Resource Statement

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. 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:
1. Mineral resource estimate prepared by Ronald G. Simpson of GeoSim Services Inc. with an effective date of January 21, 2025.
2. Mineral Resources are estimated consistent with CIM Definition Standards and reported in accordance with NI 43-101.
3. Mineral resources are not mineral reserves and do not have demonstrated economic viability.
4. 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.
5. 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
6. Totals may not sum due to rounding.

** Notes for Rhosgobel and Eiger Resources:
1. Mineral resource estimate prepared by Ronald G. Simpson of GeoSim Services Inc. with an effective date of February 25, 2026
2. Mineral Resources are estimated consistent with CIM Definition Standards and reported in accordance with NI 43-101.
3. Mineral resources are not mineral reserves and do not have demonstrated economic viability.
4. 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.
5. 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
6. Totals may not sum due to rounding.

Technical Report

The Company’s May 14, 2026 news release disclosed tungsten trioxide and silver mineral resources. During the final stages of preparation of the technical report, the Company determined not to include tungsten trioxide and silver in the mineral resource estimate for the Rhosgobel deposit. The inclusion of tungsten trioxide and silver in the mineral resource would have required the mineral resource estimate to be determined using a gold-equivalent cut-off grade under NI 43-101 requirements. The Company’s preference at this time is to instead continue the metallurgical and other work on the tungsten trioxide and silver with a view to including silver and tungsten trioxide in a future mineral resource estimate. Except for the presentation of the Rhosgobel deposit mineral resource estimate on a gold-only basis as described above, there are no material differences between the mineral resource estimates presented in the technical report and the disclosure contained in the Company’s May 14, 2026 news release.

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.

Each of the deposits at the RC Gold Project 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.

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.
