Sitka finds visible gold at RC project

Mr. Cor Coe reports SITKA INTERSECTS MULTIPLE OCCURRENCES OF VISIBLE GOLD FROM NEAR SURFACE IN INITIAL SIX DIAMOND DRILL HOLES COMPLETED AT THE CONTACT ZONE, RC GOLD PROJECT, YUKON Multiple occurrences of visible gold have been observed, beginning near surface, in the first six drill holes to be completed by Sitka Gold Corp. at the Contact zone. Visible gold has been observed in the drill core from every target that has been drilled within the Clear Creek intrusive complex so far this year, including Blackjack, Saddle, Eiger and Rhosgobel. Up to 5,000 metres of drilling is currently under way at the Contact-Pukelman zone as part of the fully financed 30,000-metre diamond drill program currently under way at Sitka's 100-per-cent-owned, road-accessible RC gold project located in the Yukon's prolific Tombstone gold belt. Over 25,000 metres of drilling has been completed at RC gold this year, where drilling has focused on expanding the Blackjack and Eiger deposits, expanding the mineralized footprint of the Saddle zone, and testing the potential of the Rhosgobel, Contact-Pukelman and Bear Paw targets to host additional intrusion-related gold deposits. Four drill rigs are currently operating on the project with two rigs at Pukelman, one rig at Rhosgobel and one rig at Bear Paw with assay results currently pending for 52 holes. "The Contact zone is now the fifth target drilled by Sitka Gold in 2025 to yield multiple occurrences of visible gold within the core of the Clear Creek intrusive complex," said Cor Coe, chief executive officer and director of Sitka Gold. "The widespread and robust gold mineralization being intersected in our drilling across this area continues to demonstrate that the RC gold project is a unique gold camp with multiple intrusions that display the potential to host several multimillion-ounce gold deposits within this relatively small three-by-five-kilometre core area. With an existing multimillion-ounce gold resource open for expansion and numerous other high-quality targets within the 431-square-kilometre land package, RC gold is quickly emerging as the foundation of a potential new mining district in the Yukon." Contact-Pukelman target Six holes totalling 2,172 metres have been completed as part of the continuing 5,000 metres of drilling planned at the Contact-Pukelman target. Drilling intersected broad intervals of strongly altered metasediments cut by several quartz monzonite, and biotite-feldspar porphyritic dikes, along with abundant, centimetre-scale, sheeted quartz veins. Visible gold was observed in the sheeted quartz veins and was often associated with arsenopyrite, bismuthinite and minor scheelite. Sitka's 2025 drill program is planned to expand the mineralized footprint of the Contact zone, test the zone with oriented diamond drill core to better understand controls on the mineralization, and test the linkage between the metasedimentary and intrusion-hosted mineralization of the Contact and Pukelman zones. The Contact zone was previously drilled in 2010 and 2011 with 1,660 metres in 12 holes of reverse circulation drilling and 254 metres in two holes of diamond drilling (see Table 1) and encountered significant mineralization in quartz veining within metasedimentary rocks up to 450 metres south of the Pukelman intrusion. Current drilling to date has traced gold mineralization across a lateral extent of approximately 900 metres by 650 metres and from surface to a depth of approximately 430 metres (see Table 1). While this is an encouraging indicator of the potential size of this target, the company cautions that additional drilling and assay results are required to confirm the extent and continuity of gold mineralization within this area. About the flagship RC gold project Sitka's 100-per-cent-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 through a secondary gravel road from the Klondike Highway, which is usable year-round and is an approximate two-hour drive from Dawson City. It is the largest consolidated land package strategically positioned midway between the Eagle gold mine and the past-producing Brewery Creek gold mine. The RC gold project 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 grams per tonne 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 National Instrument 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, PGeo, of GeoSim Services Inc., with an effective date of Jan. 21, 2025. This report is available on SEDAR+ and on the company's website. Both of these deposits begin at surface, and 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 per cent with minimal NaCN consumption (see news release dated 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 Sept. 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 Oct. 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 under way at RC gold. RC gold deposit model Exploration on the property has mainly focused on identifying an intrusion-related gold system. The property is within the Tombstone gold belt, which is the prominent host to IRGS deposits within the Tintina gold province in Yukon and Alaska. Notable deposits from the belt include: the Fort Knox mine in Alaska with current proven and probable reserves of 230 million tonnes at 0.3 g/t Au (2,471,000 ounces; Sims, 2018); Eagle gold mine with current measured and indicated resources of 233 million tonnes at a grade of 0.57 g/t Au at the Eagle Main zone (4,303,000 ounces; Harvey et al., 2022); the Brewery Creek deposit with current indicated mineral resource of 22.2 million tonnes at a gold grade of 1.11 g/t (789,000 ounces; Hulse et al., 2020); the AurMac project with an inferred mineral resource of 347.49 million tonnes grading 0.63 gram per tonne gold (7.00 million ounces); the Valley deposit, with a current measured and indicated mineral resource of 7.94 million ounces gold at 1.21 g/t and an additional inferred mineral resource of 890,000 oz at 0.62 g/t gold; and the Raven deposit with an inferred mineral resource of 1.1 million oz (19.96 million tonnes at 1.67 g/t gold).
