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, YUKON

● Step 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 directions

● Drill 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 Deposit

● Recent 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 west

● Drilling 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 Eiger

● Additional 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, CANADA – December 02, 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”) 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.

*Intervals are drilled core length, as insufficient drilling has been completed at this time to determine true widths.

“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 untapp ed 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.”

completed in 2025 has significantly expanded known gold mineralization beyond the current MRE

boundary.

Figure 2: A cross section of the Eiger Deposit showing the location of DDRCCC -25-109 which

returned 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, intercepted 325 metres beyond the current MRE boundary. These results

underscore the potential to add significant ounces to the Eiger deposit and suggest a higher-

grade component appears to be developing at depth.

Figure 3: A 3D cross section of the Eiger Deposit showing the location of new drilling with respect

to the current mineral resource estimation block model. The Eiger deposit remains open in all

directions and results from this news release have significantly expanded mineralization beyond

the current MRE boundary. Results such as the 121.0 m of 0.75 g/t Au from 248.0 m and 26.0

m of 1.28 g/t Au from 325.0 m intercepted in DDRCCC -25-109 also suggest a higher -grade

component to the deposit could be emerging a t depth, which is a characteristic of the more

advanced Blackjack deposit located 1.5 km to the west.
