Sitka Gold Corp. (CSE: SIG) (FSE: 1RF) (OTCQB: SITKF) is pleased to announce assay results from diamond drill hole DDRCCC-23-043 the third diamond drill hole of the 2023 winter drill program on the Company’s 376 square kilometre, road accessible RC Gold Project located in Yukon’s Tombstone Gold Belt, approximately 100 kilometres east of Dawson City. A resource expansion drilling program is currently underway at RC Gold where an Initial Mineral Resource Estimate of 1,340,000 ounces of gold beginning at surface and grading 0.68 g/t was announced earlier this year (see news release dated January 19, 2023).
Assay highlights from DDRCCC-23-043 include:
“The results obtained from Hole 43 are quite remarkable and further illustrate just how consistent and well-endowed the gold mineralization is at our Blackjack deposit”, stated Cor Coe, CEO and Director of Sitka Gold. “Gold mineralization was encountered at surface and continued for the entire 422.7 metre length of this drill hole, which averaged 0.74 g/t gold and had multiple occurrences of visible gold. Hole 43 was designed to fill in an area of our deposit model that was missing drill core data and test for mineralization at depth. Although the drill hole was stopped in mineralization at the end of our winter program to avoid any complications that could arise during the spring thaw, it has since been re-entered and drilling is currently underway to extend it at depth. Additional step out drilling to expand both the Blackjack and Eiger gold deposits, both of which remain wide open, will be the primary focus of our 2023 summer field season at RC Gold along with additional exploration drilling to test for continuity across the mineralized corridor (see Figure 3).”
DDRCCC-23-043 was collared at the same location as DDRCCC-21-021 (see news release dated December 13, 2021) and drilled at an azimuth of 005 degrees and a dip of -85 degrees (see Figures 1 through 3). The purpose of the hole was to fill in a gap of data in the current resource model and to extend the higher-grade mineralization in the current resource to depth.
Hole 43 intersected dominantly MQMZ from surface to 111.25 m; metasediments intruded by metre scale MQMZ dykes to 318.45 m; dominantly MQMZ with metasediments to 382.1 m and then granite dykes with inclusions of MQMZ xenoliths to the end of the hole at 426.7 m. Quartz sulphide veins intersected all units with the highest intensity of veining occurring from 250 m to the end of the hole at 426.7 m. Visible gold was noted multiple times in quartz – bismuthinite veins. (see Figure 4).
DDRCCC-23-043 was variably mineralized throughout its entire length with the interval from 4.0 m to the end of the hole at 426.7 m returning 422.7 of 0.74 g/t Au. Significant intervals of higher-grade mineralization include 40.0 m of 1.02 g/t Au from 81.0 m; 111.7 m of 1.24 g/t Au from 315.0; 28.0 m of 1.99 g/t Au and 14.0 m of 3.28 g/t Au from 345 m. Narrower intervals of multi-gram gold mineralization include 1.0 m of 6.95 g/t Au from 27.0 m; 1.0 m of 7.09 g/t Au from 53.5 m and 2.0 m of 5.00 g/t Au from 241.0 m.
Hole 43 was terminated before target depth in known mineralization to avoid complications that could arise with the onset of spring thaw conditions. The casing was left in the hole and the drill rig was left on site in anticipation of resuming drilling efforts once the spring thaw conditions had passed. Drilling at Hole 043 has since resumed.

Quality Assurance/Quality Control
On receipt from the drill site, the NQ-sized drill core was systematically logged for geological attributes, photographed and sampled at Sitka’s 2022 field camp. Sample lengths as small as 0.3 m were used to isolate features of interest, otherwise a default 2 m downhole sample length was used. 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 mass spectroscopy (ICP-MS) finish on 50 g subsamples of the prepared pulp (ALS code: Au-ICP-22). Any sample returning over 10 g/t Au 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).
About the RC Gold Project
The RC Gold Project consists of a 376 square kilometre contiguous district-scale land package located in the newly road accessible Clear Creek, Big Creek, and Sprague Creek districts in the heart of Yukon’s Tombstone Gold Belt. The project is located approximately 100 kilometres east of Dawson City and is accessed via a secondary gravel road from the Klondike Highway an approximate 2 hour drive from Dawson. It is the largest consolidated land package strategically positioned mid-way between Victoria Gold’s Eagle Gold Mine – Yukon’s newest gold mine which reached commercial production in the summer of 2020 – and Sabre Gold Mine’s Brewery Creek Gold Mine. The RC Gold Project land package comprises five underlying properties, namely, the RC, Bee Bop, Mahtin, Clear Creek, and Barney Ridge properties*. The planned 10,000 metre drill program for 2023 is currently underway and is focused on expanding the Blackjack and Eiger gold deposits, both of which remain open in all directions.
On January 19, 2023 Sitka Gold announced an Initial Mineral Resource Estimate prepared in accordance with National Instrument 43-101 guidelines for the RC Gold Property of 1,340,000 ounces of gold(1). The road accessible, pit constrained Mineral Resource is classified as inferred and is contained in two near/on-surface zones: The Blackjack and Eiger deposits. The Mineral Resource estimate is presented in the following table at a base case cut-off grade of 0.25 g/t Au:

The Initial Mineral Resource Estimate of 1,340,000 ounces of gold at the RC Gold Project is comprised of two deposits: the Blackjack deposit containing 900,000 ounces of gold at a grade of 0.83 g/t gold and the Eiger deposit containing 440,000 ounces of gold at a grade of 0.50 g/t gold (see news release dated January 19, 2023). 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 Blackjack and Eiger deposits are in close proximity to highway and power infrastructure, are road accessible year-round, remain open in all directions and are respectively located at the western and eastern end of a large, 500 metre by 2 kilometre intrusion related gold system that was recently discovered on the Property. To date, just 41 diamond drill holes have been drilled into this system for a total of approximately 14,500 metres with results of up to 201.0 m of 1.26 g/t gold from surface, including 82.0 m of 2.04 g/t gold and 19.5 m of 4.87 g/t gold at Blackjack (drill hole DDRCCC-22-040; see news release dated January 11, 2023) and 354 m of 0.41 g/t gold including 72 m of 0.72 g/t gold at Eiger (drill hole DDRCCC-21-09; see news release date August 19, 2021).
Several high priority intrusion related gold targets exist at RC Gold with nine outcropped intrusions identified to date over the 376 sq km property, however Sitka’s main focus at the RC Gold Project has been on the underlying Clear Creek Property where a large 500 metre by 2000 metre intrusion related gold system covering the area over the Blackjack, Saddle and Eiger zones was identified. Prior to the onset of the 2023 winter drilling program, the Company had drilled 38 diamond drill holes into this system for a total of approximately 13,000 metres. This drilling culminated in the discovery of the Blackjack and Eiger deposits with an initial inferred mineral resource estimate of 1,340,000 gold ounces(1).
Sitka Gold inherited a wealth of historical and current data from these properties from work spanning the last 40 years. Recent exploration work and the compilation of historical data have defined several mineralized zones with both bulk tonnage, intrusion-related gold deposit targets and high-grade, vein- and breccia-hosted gold targets. The RC Gold Project also has a common border with Victoria Gold’s Clear Creek property at its western boundary and Florin Resources’ Florin Gold property at its northern boundary.
