Sitka Drills 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, Significantly Expanding Mineralization Beyond the Current Resource Boundary at Its Eiger Deposit, RC Gold Project, YukonStep 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 directionsDrill 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 DepositRecent 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 westDrilling 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 EigerAdditional 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 100% owned, road accessible RC Gold Project ("RC Gold" or the "Project") located within the Yukon's prolific Tombstone Gold Belt. Drilling at the Eiger gold deposit has expanded the mineralized envelope beyond the current MRE boundary, with drill hole DDRCCC-25-109 intersecting 121.0 m of 0.75 g/t gold and 26.0 m of 1.28 g/t gold within 249.9 m of 0.58 g/t gold from 325.0 m outside of the current MRE. Analytical results are currently pending for 38 drill holes at RC Gold, including 26 from the new Rhosgobel discovery and the remainder from Pukelman, Contact, Bearpaw, and May-Qu.To view an enhanced version of this graphic, please visit:https://images.newsfilecorp.com/files/6144/276604_9e84119d549e4a7b_002full.jpg"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."Figure 1: A plan map of the Eiger deposit showing the location of 2025 drilling.
