  • Gold recoveries demonstrate strong and rapid leach kinetics
  • Gold extraction was mostly complete within 4 to 8 hours with minor increases to 24 hours
  • Ultimate extraction gold recoveries averaged 85 per cent and were as high as 94 per cent
  • The results of the bottle roll tests indicate that the gold is not refractory
  • Sitka Gold Corp’s (SIG) share price remains unchanged, trading at C$0.14 per share as of 12:18 pm EDT

Sitka Gold (SIG) has provided a summary of initial metallurgical bottle roll tests on six samples from the Blackjack and Eiger zones at its RC Gold Project.

The RC Gold Project is located in the Yukon.

This test work was carried out by ALS Canada Ltd. Metallurgy Services in Kamloops, B.C.

Two representative samples were selected to test gold recoveries from the Eiger Zone, and four samples were selected from the Blackjack Zone. Each of the six samples consisted of 500 grams of drill core primary crush material initially processed at ALS Global in Whitehorse, Yukon.

The samples were dominantly from non-oxidized rock taken at downhole depths ranging from 80 to 286 metres. The samples were also chosen to test gold recoveries for a range of gold grades varying from 0.92 g/t gold to as high as 35.60 g/t gold.

The samples from the Eiger Zone were of fine-grained diorite with sheeted quartz veins containing pyrite and arsenopyrite. Two of the samples from the Blackjack zone were of the megacrystic granite unit containing sheeted quartz veins with pyrite and arsenopyrite, while two were of mixed metasedimentary rock containing quartz veinlets with a minor amount of arsenopyrite.

Cor Coe, P.Geo., CEO and Director of Sitka Gold commented on the results.

“We are very pleased with these excellent metallurgical test results that demonstrate that the gold mineralization from these two zones is not refractory and has high gold recoveries with minimal NaCN consumption. This is significant as it endorses the potential for an open-pit, heap leach operation with high gold recoveries and this is typically the most economically efficient method of extracting gold from a deposit. We are rapidly expanding the known mineralization at the Blackjack zone as we continue to aggressively step out from our initial discovery hole.”

Sitka Gold Corp’s (SIG) share price remains unchanged, trading at C$0.14 per share as of 12:18 pm EDT.
