New assay results confirm and expand significant mineralized zones within the proposed Blackjack gold deposit pit
Drilling to date at the Saddle Zone, located within the Blackjack resource pit, has expanded gold mineralization across a strike length of approximately 550 m (see Figure 1); the Blackjack deposit remains open in all directions
Hole DDRCCC-26-133 at Blackjack intersected 141.5 m of 1.93 g/t gold, including 80.6 m of 3.20 g/t gold and 6.0 m of 9.46 g/t gold, one of the best intercepts drilled there to date
Drilling at Saddle returned high-grade near-surface intervals, including 17.5 m of 2.68 g/t gold beginning at 4.6 m in DDRCCC-26-135, along with high-grade intercepts from further down, including 40.0 m of 1.51 g/t gold beginning at 211.0 m in DDRCCC-26-137
Step-out drilling at Eiger returned strong gold values such as 30.5 m of 1.46 g/t gold, including 1.5 m of 25.50 g/t gold, in DDRCCC-26-139, expanding known gold mineralization west towards the Blackjack deposit; the Eiger deposit remains open in all directions
Seven drill rigs are currently turning on the Project at Blackjack, Saddle, Rhosgobel, Pukelman-Contact Zone
Approximately 50,000 m of diamond drilling has been completed to date this year in 116 drill holes across the Blackjack, Eiger, and Rhosgobel deposits and the Saddle, Contact, and Bear Paw Breccia Zones as part of the ongoing 60,000 m drill program planned for 2026
Vancouver, British Columbia--(Newsfile Corp. - September 21, 2026) - Sitka Gold Corp. (TSXV: SIG) (FSE: 1RF) (OTCQX: SITKF) ("Sitka" or the "Company") is pleased to announce assay results from 16 diamond drill holes completed at the Blackjack deposit, the Saddle Zone and the Eiger deposit, and to provide an update on the 60,000 metre diamond drilling program currently underway at its 100% owned, road accessible RC Gold Project ("RC Gold" or the "Project") in Canada's Yukon Territory.
These results show growth at the Blackjack-Eiger area on three fronts:
Saddle Zone: Thirteen holes have now traced near-surface gold mineralization across approximately 550 metres of strike east of the current Blackjack resource. All of it lies within the Blackjack resource pit shell. Some of the higher-grade intervals begin within five metres of surface, including 14.2 m of 2.74 g/t gold in hole 136 and 17.5 m of 2.68 g/t gold in hole 135. All of this mineralization sits outside the current mineral resource estimate, so it could add ounces inside the planned pit.
Blackjack: Hole 133 intersected 141.5 m of 1.93 g/t gold, including 80.6 m of 3.20 g/t gold and 6.0 m of 9.46 g/t gold, (below the current resource shell). This is one of the strongest intervals drilled at the Project to date. It continues the high-grade zone previously intersected in holes 121 and 132, and further supports the underground potential beneath the Blackjack resource pit.
Eiger: Step-out drilling returned 30.5 m of 1.46 g/t gold, including 6.5 m of 6.15 g/t gold (hole 139). These results extend mineralization west of the current Eiger resource, toward the Saddle Zone.
With Saddle extending mineralization east from Blackjack and Eiger growing to the west, the two deposits are now growing toward each other along the 2 km long Blackjack-Eiger area. This supports the Company's view that they may form part of one larger, continuous gold system.

"We have now traced near-surface gold mineralization for roughly 550 metres east of the Blackjack resource, all inside the resource pit shell," stated Cor Coe, CEO and Director of Sitka Gold. "This is mineralization that isn't in our current resource and has the potential to add significant near-surface ounces. At the same time, the high-grade core at Blackjack continues to deliver at depth. The intercept of 80.6 metres of 3.20 g/t gold from hole 133 is among the best intervals we have drilled at RC Gold and further supports an underground opportunity beneath the pit at Blackjack. At Eiger, we continue to push gold mineralization west toward Saddle. Viewed together, these results show that the Blackjack and Eiger deposits are growing toward each other, and we see real potential for them to ultimately form one larger, continuous deposit. With more than 30,000 metres drilled at Blackjack and Saddle since the January 2025 resource estimate, we look forward to capturing this growth in an updated mineral resource estimate once we have completed the planned 60,000 metre drill program."

A coherent core of greater than 1.0 g/t gold material is also illustrated (in purple) at Blackjack. Drill results from this release confirm gold mineralization extends up to 550 metres east of the Blackjack resource and within the pit limits. Drilling at Eiger confirms the mineralization continues west of the current Eiger resource. The resource pit-limits for these deposits are currently 200 m apart. Recent results show that mineralization at these deposits continues to grow towards each other and may ultimately form one larger, continuous gold system.

The 2026 drill program continues to successfully intersect broad zones of Reduced Intrusion-Related Gold System (RIRGS) mineralization at the Blackjack, Eiger, and Rhosgobel deposits and continues to expand and define the known gold mineralization at each area. The program will continue to define these broad zones of mineralization as well as target new zones of previously defined mineralization such as the Pukelman/Contact zones, Saddle zone and Bear Paw Breccia zone.
Drilling at the Saddle Zone has now traced gold mineralization across a strike length of approximately 550 metres east of the current Blackjack resource. All of it lies within the Blackjack resource pit shell and outside the current mineral resource estimate. Results from this release show two zones of mineralization. The first is a near-surface zone that begins within five metres of surface in several holes, including 17.5 m of 2.68 g/t gold in hole 135 and 14.2 m of 2.74 g/t gold in hole 136. The second is the deeper zone first identified in 2025, which returned 71.2 m of 1.15 g/t gold, including 14.8 m of 3.63 g/t gold in hole 140 and 40.0 m of 1.51 g/t gold, including 10.0 m of 3.54 g/t gold in hole 137. Visible gold was observed in several holes at the Saddle Zone within narrow sheeted quartz veins cutting across gently north-dipping megacrystic quartz monzonite sills and steeply dipping dykes, as well as the adjacent hornfelsed sedimentary rocks, consistent with previous drilling at Saddle (see news release July 17, 2025). Near-surface, higher-grade gold within the pit shell has the potential to add significant ounces to the Blackjack deposit. Continued expansion of the Saddle Zone to the east also narrows the gap between the Blackjack and Eiger deposits and supports the Company's view that the two may be connected as one larger gold system.
* 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 RC Gold Project
Sitka's 100% owned, flagship RC Gold Project consists of a 447 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 one of the largest consolidated land packages strategically positioned mid-way between the Eagle Gold Mine and the past producing Brewery Creek Gold Mine.
The RC Gold Project hosts an indicated MRE of 1,291,000 ounces of gold and an inferred MRE of 3,829,000 ounces of gold (see Table A below) hosted within three at surface, road-accessible pit constrained deposits. The 60,000 metre drill program planned for 2026 is focused on expanding all three known deposits in addition to testing other high potential targets in close proximity to the current resources.

* Notes for Blackjack Resources:
- Mineral resource estimate prepared by Ronald G. Simpson of GeoSim Services Inc. with an effective date of January 21, 2025.
- Mineral Resources are estimated consistent with CIM Definition Standards and reported in accordance with NI 43-101.
- Mineral resources are not mineral reserves and do not have demonstrated economic viability.
- Mineral resources are constrained by an optimized pit shell using the following assumptions: US$2000/oz Au price; a 45° pit slope; assumed metallurgical recovery of 85%; mining costs of US$2.00 per tonne; processing costs of US$10.00 per tonne; G&A of US$4.00/t.
- The base case cut-off of 0.3 g/t Au is believed to provide a reasonable margin over operating and sustaining costs for open-pit mining and processing
- Totals may not sum due to rounding.
** Notes for Rhosgobel and Eiger Resources:
- Mineral resource estimate prepared by Ronald G. Simpson of GeoSim Services Inc. with an effective date of February 25, 2026
- Mineral Resources are estimated consistent with CIM Definition Standards and reported in accordance with NI 43-101.
- Mineral resources are not mineral reserves and do not have demonstrated economic viability.
- Mineral resources are constrained by an optimized pit shell using the following assumptions: US$3000/oz Au price; a 45° pit slope; assumed metallurgical recovery of 85%; mining costs of US$2.50 per tonne; processing costs of US$14.00 per tonne; G&A of US$4.00/t.
- The base case cut-off of 0.3 g/t Au is based on a gold price of US$2500/oz and believed to provide a reasonable margin over operating and sustaining costs for open-pit mining and processing
- Totals may not sum due to rounding.
All of these deposits begin at surface and are potentially open pit minable. Initial bottle roll metallurgical testing confirmed the non-refractory characteristics of the gold mineralization and returned gold extraction rates averaging around 85% for the Blackjack and Eiger deposits. Further metallurgical testwork in 2024 for Blackjack and Eiger returned recoveries ranging from 77.6 to 93% for gravity followed by cyanidation. Initial bottle roll testing for Rhosgobel has confirmed non-refractory characteristics of the gold mineralization with two composite samples returning gold recoveries of 89% and 96%. Additional metallurgical testing at Rhosgobel has returned an average gold recovery of 94.3% using conventional whole ore cyanidation leaching and an initial recovery of 84.7% tungsten in rougher concentrate using conventional flotation. Metallurgical testing for potential silver recovery has not yet been completed.
For the purposes of the current resource model, it is assumed that a likely mill flowsheet would consist of a gravimetric, flotation, and cyanidation circuit.

Quality Assurance/Quality Control
On receipt from the drill site, the HTW/NTW-sized drill core was systematically logged for geological attributes, photographed and sampled at Sitka's core logging facility. Sample lengths as small as 0.3 m were used to isolate features of interest, otherwise a default 2.0 m downhole sample length was used. Each sample is identified by a unique sample tag number which is placed in the bag containing the core to be assayed. Core was cut in half lengthwise along a predetermined line, with one-half (same half, consistently) collected for analysis and one-half stored as a record. Standard reference materials, blanks and duplicate samples were inserted by Sitka personnel at regular intervals into the sample stream. Bagged samples were placed in secure bins to ensure integrity during transport. They were delivered by Sitka personnel or a contract expeditor to ALS Laboratories' preparatory facility in Whitehorse, Yukon, with analyses completed in North Vancouver.
ALS is accredited to ISO 17025:2005 UKAS ref. 4028 for its laboratory analysis. Samples were crushed by ALS to over 70 per cent passing below two millimetres and split using a riffle splitter. One-thousand-gram splits were pulverized to over 85 per cent passing below 75 microns. Gold determinations are by fire assay with an inductively coupled plasma atomic emission spectroscopy (ICP-AES) finish on 50 g subsamples of the prepared pulp (ALS code: Au-ICP-22). Any sample returning over 10 g/t gold was re-analyzed by fire assay with a gravimetric finish on a 50 g subsample (ALS code: Au-GRA21). In addition, a 51-element analysis was performed on a 0.5 g subsample of the prepared pulps by an aqua regia digestion followed by an inductively coupled plasma mass spectroscopy (ICP-MS) finish (ALS code: ME-MS41). All drill core at the Rhosgobel deposit was selected for additional XRF analysis on a lithium borate fusion (ALS code: XRF-15b) for WO3.
