VANCOUVER, CANADA – November 25, 2025: Sitka Gold Corp. (“Sitka” or the “Company”) (TSX-V:SIG) (FSE:1RF) (OTCQB:SITKF) is pleased to announce additional analytical results from drilling completed at its 100% owned, road accessible RC Gold Project (“RC Gold” or the “Project”) within the Yukon’s prolific Tombstone Gold Belt. Drilling at the Blackjack area has expanded the known mineralized envelope at the Blackjack Gold Deposit, expanded the Saddle Zone gold mineralization, identified a deeper zone of strong gold mineralization at Saddle, and discovered a new area of gold mineralization at Blackjack South located approximately 300 metres south of the current Blackjack deposit and within the current proposed pit limits.

At the Blackjack Deposit, drill hole DDRCCC-25-099 intersected 310.0 m of 0.61 g/t gold, including 172.4 m of 0.90 g/t gold and 26.8 m of 1.04 g/t gold, and 33.4 m of 2.40 g/t gold at the edge of the current MRE extending the known mineralization further to the southwest (see Figure 1). DDRCCC-25-102 returned 191.8 metres of 0.65 g/t gold including 24.3 m of 2.33 g/t gold, highlighting the presence of strong gold mineralization outside the southwest margin of the current MRE (see Figure 1).

At the Saddle Zone DDRCCC-25-104 intersected 44.4 metres of 1.33 g/t gold from 4.6 metres extending the near surface mineralization at the Saddle Zone further to the west (see Figure 1). The Saddle Zone is within the pit limits of the Blackjack Deposit but is not included in the current MRE and drilling has extended the strike of mineralization at Saddle to approximately 300 metres. Drilling at Blackjack South (holes DDRCCC-25-105, -108, -110) has intersected a new quartz monzonite dyke within the proposed pit limits at Blackjack, adding a new mineralized target approximately 300 metres south of the current MRE boundary where drillhole DDRCCC-25-110 intersected 44.5 m of 0.70 g/t gold including 8.8 metres of 1.18 g/t gold. Mineralization at Blackjack south consists of sheeted quartz veins cutting the feldspar megacrystic quartz monzonite and adjacent metasediments.

“Drilling at the Blackjack and Saddle zones continues to reinforce the potential for significant ounces to be added within the conceptual pit shell of our Blackjack gold deposit,” stated Cor Coe, CEO and Director of Sitka Gold. “While the long, robust drill intercepts returned this season continue to expand the mineralized envelope at Blackjack, which remains open in all directions, we are quite excited with what we are seeing at Saddle, where results such as 44.4 metres of 1.33 g/t gold beginning at surface in hole 104 highlight the potential to add near surface higher-grade gold mineralization within the proposed pit limits. Furthermore, results such as the 4.0 metres of 3.90 g/t gold beginning at 142.0 metres in hole 098 suggest that a deeper zone of higher-grade mineralization is also beginning to emerge at Saddle. In addition, a new zone of gold mineralization has been discovered about 300 metres south of the Blackjack resource envelope where step out drilling has intercepted strong gold values such as 44.5 metres of 0.70 g/t gold in hole 110, which included 8.8 metres of 1.18 g/t gold and a separate interval of 2.0 metres of 4.07 g/t gold. We look forward to following up on these latest drill results as we continue to unlock the potential at the Blackjack deposit, which is just one of our many exciting targets within what is quickly becoming a district-scale, multi- deposit gold camp at RC Gold.”

These results continue to demonstrate the presence of significant gold mineralization in the metasedimentary rock within and adjacent to the megacrystic quartz monzonite.

This intersection also demonstrates the presence of gold mineralization in the metasediments adjacent to the intrusive megacrystic quartz monzonite.

Blackjack Drilling

Drilling at Blackjack in 2025 which included 26 holes for approximately 10,494 m was successful in extending the known mineralization at the Blackjack deposit as well as extending the strike length of known mineralization at the Saddle zone, identifying new deeper mineralization at Saddle, and identifying new mineralization at Blackjack South. The three holes drilled at Blackjack South were successful at identifying a new zone of mineralization within the proposed Blackjack pit outline.

At the Saddle Zone, 11 holes for a total 2,918 meters have been completed in 2025. Received results continue to define the presence of dykes and sills with strong gold mineralization hosted both within the dykes and sills and the host metasedimentary rock. The near surface gold mineralization defined to date at the Saddle Zone is within the current proposed pit outline for the Blackjack Deposit resource, but is approximately 300 metres east of the current Mineral Resource Estimate (MRE) outline. This mineralization therefore has the potential to expand and add ounces to the current MRE. In addition, drill holes at Saddle have intersected a deeper zone of mineralization such as drillhole DDRCCC-25-086 which intersected a second deeper zone of 4.1 m of 1.45 g/t gold and DDRCCC-25-089 which intersected a second deeper zone of 4.0 m of 4.52 g/t gold from 236.0 m within mineralized dykes and sills (see news release dated September 4, 2025).

• 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.

The map highlights the numerous drill targets that Sitka has outlined within the CCIC which all are connected by the road network on the project and occur in an area measuring five (5) km north-south and twelve (12) km east-west. Additional areas highlighted by strong gold in soil anomalies are being advanced to the drill ready stage with additional geological work in 2025.
