 Vancouver, British Columbia--(Newsfile Corp. - August 19, 2025) - Sitka Gold Corp. (TSXV: SIG) (FSE: 1RF) (OTCQB: SITKF) ("Sitka" or the "Company") is   pleased to announce that multiple occurrences of visible gold have  been  observed, beginning near surface, in the first six drill holes to  be  completed by the Company at the Contact zone. Visible gold has now  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 underway at the Contact-Pukelman zone (see Figures 3, 4 and   6) as part of the fully funded 30,000 metre diamond drill program   currently underway at Sitka's 100% 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 growing 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 (see Figure 6) with assay results   currently pending for 52 holes.Visible gold observed in first six diamond drill holes drilled at the Contact zone
 
Drilling to date has traced mineralization along a strike of approximately 900 m and to a depth of approximately 430 m from surface at the Contact zone
 
Visible gold has now been observed in drill core from all five targets drilled within the Clear Creek Intrusive Complex this year
 
First drilling completed since 2010/2011 that produced historical intersections in Contact zone of 38.3 m of 1.54 g/t gold, 74.3 m of 1.01 g/t gold and 43.4 m of 1.20 g/t gold in Holes CC11-043, 044, 045 respectively and 10.7 m of 20.46 g/t gold in CC10-22 
 
Six holes totalling 2,172 m completed as part of the ongoing 5,000 m of drilling planned at Contact-Pukelman target
 
Drilling has also recently commenced at the Bear Paw target
 
Results   are currently pending for all holes drilled at Contact-Pukelman along   with holes completed across Blackjack, Saddle, Eiger, Rhosgobel and  Bear  Paw
 
Over 25,000 metres of the ongoing 30,000 m planned drill program completed with assays 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, CEO 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 multi-million ounce gold deposits within  this  relatively small 3 by 5 kilometre core area. With an existing   multi-million 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  ongoing  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 dykes,  along with abundant, cm scale, sheeted quartz veins.  Visible gold was  observed in the sheeted quartz veins and was often  associated with  arsenopyrite, bismuthinite, and minor scheelite (see  Figures 1 and 2).
 
 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 2 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 x 650 metres and from surface to a  depth of approximately 430  metres (see Figure 3 and 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.
 
 *  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.

 About the Flagship RC Gold Project
 
 Sitka's   100% 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 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 the largest consolidated land package strategically positioned   mid-way between the Eagle Gold Mine and the past producing Brewery Creek   Gold Mine.
 
 The RC Gold Project now 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 g/t 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 NI   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, P. Geo., of GeoSim Services Inc. with an   effective date of January 21, 2025. This report is available on SEDAR+ (https://api.newsfilecorp.com/redirect/jNNDPSLZn2) and on the Company's website ( www.sitkagoldcorp.com).
 
 Both   of these deposits begin at surface, 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% with minimal NaCN consumption (see News Release 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 September 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 October 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 underway at RC Gold.
