Sitka Increases Gold Mineral Resource Estimate to 1.3 Million Ounces Indicated and 1.5 Million Ounces Inferred at Its RC Gold Project in Yukon

• Updated Mineral Resource Estimate (“MRE”) at the Company’s 100% owned Blackjack gold deposit located at the RC Gold Project, Yukon using a 0.3 g/t gold cut-off grade:

○ Indicated Mineral Resource: 1,291,000 ounces of gold at a grade of 1.01 g/t

○ Inferred Mineral Resource: 1,044,000 ounces of gold at a grade of 0.94 g/t

• The updated MRE represents a significant increase in both average grade and contained ounces at the Blackjack deposit where an initial inferred MRE of 900,000 ounces of gold at a grade of 0.83 g/t with a cut-off of 0.25 g/t gold was announced in 2023 (see Company News Release dated January 19, 2023).
• The updated MRE at Blackjack has a well defined and consistent core of 1 g/t or greater material that extends from surface to a depth of 660 m and remains open in all directions.
• Initial metallurgical testing indicates that the gold in the Blackjack deposit is not refractory and has high recoveries of up to 94% with minimal NaCN consumption (see News Release dated July 13, 2022).
• 30,000 m of drilling planned at RC Gold this year to continue upgrading and expanding the Blackjack resource and further develop other significant centres of gold mineralization within the Clear Creek Intrusive Complex (“CCIC”), including the Eiger Deposit, which contains an initial inferred MRE of 440,000 ounces of gold (see Table 3 and Figure 5), and the Saddle, Rhosgobel, Contact, Pukelman, Bear Paw and Josephine targets (see Figures 4 and 5).

Sitka Gold Corp. (TSXV: SIG) (FSE: 1RF) (OTCQB: SITKF) (“Sitka” or the “Company”) is pleased to announce an updated Mineral Resource Estimate (“MRE”) in accordance with the Canadian Institute of Mining, Metallurgy and Petroleum (“CIM”) Definition Standards incorporated by reference in National Instrument 43-101 (“NI 43-101”) for the Blackjack gold deposit located on the Company’s road accessible, contiguous 431 square kilometre RC Gold Project (“RC Gold” or the “Project”) located in the Yukon’s prolific Tombstone Gold Belt (“TGB”). The MRE was prepared on behalf of the company by GeoSim Services Inc. and is based on additional drilling completed by the Company in 2023 and 2024.

“We are thrilled with the remarkable growth of the Blackjack gold deposit that has been achieved in just two years at our flagship RC Gold Project in Yukon,” stated Cor Coe, Director and CEO of Sitka. “With just 11,725 metres of additional diamond drilling since the initial mineral resource estimate was published in 2023, we have substantially increased the number of ounces contained at the Blackjack gold deposit by over 2.5 times while also increasing the overall grade. This updated resource estimation reflects the quality of this discovery, highlighted by the robust, non-refractory gold mineralization that has a significant core of higher-grade material of 1 gram per tonne or greater that begins at surface and extends to a currently defined depth of 660 metres (see Figure 2). These results also illustrate the exceptional scalability that can be achieved with relatively modest drilling at RC Gold and emphasize the potential of this extensive gold system to host world-class, multi-million ounce gold deposits. The Blackjack deposit provides a benchmark for what can be achieved at the several other intrusions within the Clear Creek Intrusive Complex, which have all been shown to host similar gold mineralization. With 30,000 metres of diamond drilling planned for this year – which exceeds all the drilling we have completed to date at RC Gold – we are on track to rapidly advance what is quickly becoming a multi-million ounce gold camp.”

Updated Mineral Resource Estimate
The updated Mineral Resource Estimate (MRE) for the Blackjack Zone includes 11,725 m of drilling in 25 holes in addition to the 7,074 m of drilling in 21 holes which comprised the initial resource estimate. At a 0.30 g/t gold cut off grade, the updated MRE at Blackjack includes an Indicated resource of 39,962,000 tonnes at 1.01 g/t gold containing 1,291,000 ounces and an Inferred resource of 34,603,000 tonnes at 0.94 g/t gold containing 1,044,000 ounces (Figure 1 and Table 1). A 0.30 g/t cut of grade is achievable because of the nature of the deposit, the good gold recoveries obtained from initial metallurgical testing and the favourable logistics of the RC Project, including year-round road access and proximity to infrastructure.

The modelling for the updated MRE identified a consistent higher grade core of the deposit that contains greater the 1 g/t Au material that trends from surface to a currently identified depth of 660 m (Figures 2 and 3). The morphology and grade of this mineralization allows for the possible development of a higher-grade starter pit and a faster capital cost payback of potential future mine development. The MRE is also relatively insensitive to changing cut-off grades, further confirming the quality of the resource (see Table 2).

A National Instrument 43-101 Technical Report describing the details of the mineral resource estimate is in preparation and will be filed on SEDAR within 45 days of this news release.

Notes:
1. Mineral resource estimate prepared by Ronald G. Simpson of GeoSim Services Inc. with an effective date of January 21, 2025.
2. Mineral Resources are estimated consistent with CIM Definition Standards and reported in accordance with NI 43-101.
3. Mineral resources are not mineral reserves and do not have demonstrated economic viability.
4. 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.
5. 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.
6. Totals may not sum due to rounding.

A 30,000 metre diamond drilling program planned for 2025 will focus on further expansion of the 2 km long Blackjack-Eiger area with 15,000 metres of drilling. An additional 10,000 metres of drilling is planned at Rhosgobel to follow up on the initial diamond drilling conducted by Sitka in late 2024 that discovered intervals of significant gold mineralization, including 119.0 metres of 1.05 g/t gold (see news releases dated November 25) and 5,000 metres of drilling is planned at Pukelman where initial drilling in late 2024 returned over a 100 gram-metre gold interval within the intrusion and on the periphery of a large geochemical anomaly target (see news release dated January 7, 2025).

About the flagship RC Gold Project
The 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 prepared in accordance with National Instrument 43-101 (“NI 43-101”) guidelines that are contained in two zones: the Blackjack and Eiger deposits with 1,291,000 ounces of gold grading 1.01 g/t gold in an indicated category and 1,044,000 grading 0.94 g/t in an inferred category at Blackjack and 440,000 ounces grading 0.50 g/t gold in an inferred category at Eiger. Both of these deposits are at/near 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). The Mineral Resource Estimate is presented in the following table:

Table 3: Current pit-constrained gold resources at the RC Gold Project

Notes:
1. The Eiger deposit resource is from the mineral resource estimate prepared in 2023 which was not updated as no additional drilling has been completed.

To date, 72 diamond drill holes have been drilled into this system by the Company 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 m of 1.34 g/t gold Including 124.8 m of 2.01 g/t gold and 55.0 m 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).
