About the RC Gold Project
Sitka’s 100% owned, flagship 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 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 now has pit-constrained mineral resources that are contained in three zones: the Blackjack, Eiger, Rhosgobel gold deposits with a total Mineral Resource Estimate of 3.8 million ounces gold inferred and 1.3 million ounces gold indicated at RC Gold including 1,291,000 ounces of gold in 39,962,000 tonnes grading 1.01 g/t gold in an indicated category and 1,044,000 ounces of gold in 34,603,000 tonnes grading 0.94 g/t in an inferred category at Blackjack and 535,000 ounces of gold in 32,143,000 tonnes grading 0.52 g/t gold in an inferred category at Eiger, and an additional 2,250,000 ounces gold in 100,677,000 tonnes grading 0.70 g/t gold in the inferred category at Rhosgobel. The Blackjack resource estimate numbers are supported by the technical report for RC Gold, prepared in accordance with NI 43-101 standards, entitled “Clear Creek Property, RC Gold Project NI 43-101 Technical Report Dawson Mining District, Yukon Territory”, prepared by Ronald G. Simpson, P. Geo., of GeoSim Services Inc. with an effective date of January 21, 2025. A National Instrument 43-101 Technical Report describing the details of the mineral resource estimates for Rhosgobel and Eiger is in preparation and will be filed on SEDAR within 45 days of this news release.
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%.
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.
