New drill intercepts of up to 156.9 meters at 1.00 g/t gold from surface and visible gold along 1.1 kilometers of strike strengthen the development of the Rhosgobel target within Sitka Gold’s RC Gold Project.
Sitka Gold Reports Further Strong Drill Results from Rhosgobel
Sitka Gold Corp. (TSX-V: SIG; FSE: 1RF; OTCQB: SITKF) has released further strong drill results from the Rhosgobel discovery at its 100% owned, road-accessible RC Gold Project in the Yukon. The newly reported assays for drill holes DDRCRG-25-018 to DDRCRG-25-028 significantly extend known gold mineralization and support the picture of an extensive Reduced Intrusion-Related Gold System (RIRGS) deposit within the Clear Creek Intrusive Complex (CCIC).
Among the best results is drill hole DDRCRG-25-027, which returned 156.9 meters at 1.00 g/t gold from a depth of 93 meters. This includes 94.0 meters at 1.41 g/t gold and a further section of 38.0 meters at 2.03 g/t gold. Locally, 6.0 meters grading 7.58 g/t gold and 2.0 meters grading 19.30 g/t gold were also intersected.
Drill hole DDRCRG-25-024 also returned 146.7 meters at 1.05 g/t gold from a depth of only 21.3 meters, including 12.0 meters at 3.89 g/t gold. Additional drill holes such as DDRCRG-25-019, -020, -021, -022, -026, and -028 returned long intervals between approximately 70 and 126 meters averaging approximately 0.7 to 1.0 g/t gold, predominantly starting near surface.
Rhosgobel: Gold deposit begins at surface and remains open in all directions
With the new results, Sitka Gold has further expanded the mineralized zone of the Rhosgobel target. Gold mineralization begins directly at surface, has reached depths of over 400 meters to date, and remains open in all directions. Drilling has now traced the mineralized structure over a strike length of approximately 1.1 kilometers, underlain by a gold-in-soil anomaly measuring approximately 2.0 x 1.5 kilometers with values of up to over 500 ppb gold. The company particularly highlights that 19 of the first 28 drill holes at Rhosgobel – including the two discovery drill holes from 2024 – have returned over 100 grams of gold per meter (g * m) (i.e., grade times thickness)!
Visible gold was documented in all drill holes in the various vein types, often associated with bismuthinite, scheelite (tungsten mineral), and molybdenite. According to the company, analytical results of a further 15 drill holes from the 2025 campaign at Rhosgobel are still pending.
In addition to gold, it is noteworthy that tungsten mineralization is consistently observed in the Rhosgobel target area, mainly in the form of scheelite, which occurs partly as coarse-crystalline inclusions in quartz and quartz-tourmaline veins and partly as smaller crystals in the finer layered quartz veins. Sitka Gold considers these observations to be an indication that tungsten could be a potential by-product of possible gold production in the future!
However, the analytical method used to date (ME-MS41) only provides a partial solution for the scheelite-bearing material, meaning that further investigations are necessary to determine reliable tungsten grades. To this end, the company has submitted additional samples – including from drill hole DDRCRG-25-004 – for various analytical methods such as lithium borate fusion with XRF, sodium peroxide fusion, and four-acid digestion.
In a previous drill hole (DDRCRG-24-002), zones of high-grade tungsten mineralization were identified, including 6.98 meters grading 0.39% WO₃ and 0.61 meters grading 4.73% WO₃ within broader intervals of 75.5 meters grading 0.132% WO₃ and 46.19 meters grading 0.121% WO₃. Concurrently, this hole returned 173.3 meters at 0.60 g/t gold from 97 meters, including 28.4 meters at 1.40 g/t gold and 12.4 meters at 2.40 g/t gold. Sitka Gold intends to examine further samples after completion of the ongoing laboratory work to more accurately assess the distribution and economic significance of the tungsten grades at Rhosgobel.
May-Qu target and overall picture of the RC Gold Project
In addition to Rhosgobel, Sitka Gold drilled two holes at the May-Qu target in 2025 to follow up on a zone of previously collected high-grade rock samples to the south and southwest. Both holes intersected granodiorite with layered quartz veins and sulfide mineralization (including arsenopyrite, pyrrhotite, chalcopyrite, and bismuthinite). The best values were 2.0 meters at 0.70 g/t gold in hole MQ-25-002, along with elevated arsenic and bismuth grades. According to the geologists’ interpretation, this indicates that the system intensifies towards the southwest. Several sub-targets in the May-Qu area have not yet been drilled; follow-up work is already planned for 2026.
The RC Gold Project remains Sitka Gold’s flagship property. The contiguous land package covers approximately 431 square kilometers in the heart of the Tombstone Gold Belt in the Yukon, about 100 kilometers east of Dawson City, and is accessible via a year-round gravel road from the Klondike Highway. The project is strategically located between the producing Eagle Gold Mine and the former Brewery Creek Mine.
RC Gold already has pit-constructed resource estimates for the Blackjack and Eiger gold deposits. Blackjack has 1.291 million ounces of gold in the indicated category (39.96 million tonnes at 1.01 g/t gold) and 1.044 million ounces of gold in the inferred category (34.60 million tonnes at 0.94 g/t gold). For Eiger, an additional 440,000 ounces of gold are reported in the inferred category (27.36 million tonnes at 0.50 g/t gold). Both deposits start at surface and are classified as potentially open pit mineable; according to Sitka Gold, metallurgical tests show non-refractory mineralization with gold recovery rates predominantly in the range of 80-90%.
To date, Sitka Gold has completed a total of 165 diamond drill holes totaling 59,770 meters at the Clear Creek Intrusive Complex, as well as additional drilling in the May-Qu intrusion area. Previous highlight drill holes include 678.1 meters at 1.04 g/t gold from surface in hole DDRCCC-24-068 at Blackjack and 352.8 meters at 1.55 g/t gold, including 108.9 meters at 3.27 g/t gold and 45.0 meters at 4.52 g/t gold, in hole DDRCCC-25-075.
With the new results from Rhosgobel, Sitka Gold is strengthening the basis for a possible third major gold deposit within the RC Gold Project. Together with the existing resource estimates for Blackjack and Eiger as well as other targets such as Contact, Pukelman, Bearpaw and May-Qu, the company is working to further expand the project area in the Tombstone Gold Belt as an emerging gold camp in the Yukon.
