RC GOLD PROJECT
The RC Gold Project, comprised of the RC Gold Property and the Mahtin Gold Property, is a district scale contiguous land package of 1,579 claims covering approximately 32,800 hectares (328 km2 or 81,000 acres) within the fertile and highly prospective Tombstone Gold Belt region (Figures 1 & 2). This belt hosts Victoria Gold’s Eagle Deposit (3.6 million ounces Au)⁽¹⁾, Golden Predators’ Brewery Creek Deposits (1.5 million ounces gold)⁽²⁾ and AM Gold’s Red Mountain Deposit (1.95 million ounces gold)⁽³⁾ as well as numerous placer gold deposits. The Tombstone Gold Belt is within the larger Tintina Gold Belt which also hosts Kinross Golds’ Fort Knox deposit in Alaska (3 million ounces of gold)⁽⁴⁾ (Figure 1).

RC GOLD PROPERTY
The RC Gold property is comprised of 132 claims covering an area of approximately 2600 hectares (6425 acres) and lies about 100 km east of Dawson City, Yukon at the headwaters of Clear Creek and Big Creek, a major placer mining district that is serviced by a network of gravel roads and trails. A new placer mine access road traverses through the south side of the Property and provides access to the

Property. This road connects to the Clear Creek road which connects to the Klondike Highway, approximately mid-way between Stewart Crossing and Dawson (Figure 1). The claim block is strategically located within the heart of the Tombstone Gold Belt and is surrounded by junior mining companies, including a common boundary with Victoria Gold (Figure 2).
Placer Mining first began on Clear Creek in the late 1800's and the first quartz claims were staked in the early 1900's. Placer mining has continued to the present, with a dredge operating on Clear Creek from 1943 to 1954 and again between 1981 and 1987. Several active placer mines continue to operate in the Clear Creek drainage and new placer mining activity has recently begun in Big Creek.
The first modern hard rock exploration in the area took place in the 1970's, targeting silver, tin and tungsten, metals commonly associated with Intrusion Related Gold deposits. High grade gold-silver and silver-lead-zinc veins have also been prospected.
In the 1990's, exploration shifted to bulk tonnage gold after the discovery of the Fort Knox gold deposit in Alaska, in a similar geological environment. Explorers in the vicinity of The RC Gold property included Noranda, Ivanhoe Goldfields, Kennecott and Newmont. These companies carried out geological mapping, geochemical and geophysical surveys and several campaigns of drilling. More recently, in the 2000's, Thor Explorations, StrataGold and Golden Predator have explored on the west side of the RC Property, while Ryan Gold (now StrikePoint) explored to the east. AM Gold’s Red Mountain Property, an Intrusion Related gold target approximately 10 km to the northeast, has also seen exploration throughout the 2000’s and has a resource of 1.95 million of gold ounces defined.
In 2017, the Property was optioned to Pacific Ridge Exploration Ltd. who completed a program of geological mapping and property-wide soil sampling that same year. Pacific Ridge conducted additional soil sampling, mapping and a small geophysical survey in 2018. These work programs produced encouraging results with several previously unknown gold-in-soil anomalies shown to be present on the Property. In 2019, after acquiring the Property, Sitka Gold followed up on these results with a soil sampling and geophysical survey program designed to expand and fill in the previous geophysical and geochemical anomalous zones that had been identified. Together, this work has defined six high-priority gold targets where the gold values, plus the associated pathfinder metals, are typical of mineralization associated with Intrusion Related Gold deposits. Two of these mineralized zones appear to be contiguous representing an Intrusion Related Gold target that is 2 km long by 0.5 km wide (see Figure 3).

The area of the RC Gold property is underlain by phyllite, quartzite, calc-phyllite, calc-silicate, grit and marble of the Proterozoic to Early Cambrian Hyland Group. These metasedimentary rocks are imbricated by thrust faults of Jurassic and Early Cretaceous age. The Clear Creek area is in the hanging wall of the Robert Service Thrust.
At the headwaters of Clear Creek, six Tombstone-style intrusions with ages of approximately 92 my, include the Saddle, Eiger, Pukelman, Rhosgobel, Josephine and Big Creek stocks. They have surface exposures ranging from 0.2 to 3.5 km2. The Saddle, Pukelman and Rhosgobel stocks are composed of medium- to coarse-grained quartz monzonite The Josephine and Big Creek stocks are composed of fine- to medium-grained, equigranular granodiorite. The Eiger stock is composed of fine to medium-grained, equigranular diorite with rare mafic phenocrysts.
Contact metamorphism of the Hyland Group country rocks extends for as much as 0.5 km around the stocks and typically occurs as resistant, rusty weathering biotite hornfels.
The RC Gold project lies within the heart of the Tintina Gold Belt. Hart (2005) has estimated a total metal endowment on the order of 70 million ounces of gold. Key deposits include Brewery Creek and the Eagle deposit (Dublin Gulch) in Yukon and Fort Knox, True North, Pogo and Donlin Creek in Alaska. Most of these deposits are characterized by flanking placer gold creeks.
The immediate area of the RG Gold project is characterized by several styles of mineralization associated with the Tombstone-aged intrusions, but the most important of these is sheeted veins, stockworks and breccias that occur within the intrusions and adjacent hornfels. These veins typically contain minor amounts of sulphide, including arsenopyrite, pyrite and rarely pyrrhotite. Other minerals include scheelite (tungsten), molybdenite, galena, chalcopyrite and bismuthinite. Arsenic, bismuth, tellurium, antimony, tungsten and molybdenum are typical pathfinder elements when prospecting for gold in these types of systems.
MAHTIN GOLD PROPERTY
The Bos Stock intrudes into sedimentary rocks of the Hyland Group, covering an area of 3.5km by 3.0km. Work by Ryan Gold shows a significant soil anomaly covering the area. Advanced geological maps have been completed for the May-Qu block. Grab samples have returned up to 3.37g/t Au over the intrusion, and 313g/t Ag in the distal vein systems. Next step would be drilling to assess extent and mineralization of pluton below sedimentary cap.
