Granite Creek Copper Ltd. reported positive metallurgical results in support of the upcoming Preliminary Economic Assessment for the Carmacks copper-gold-silver project located in the Minto copper district, within the traditional territories of the Little Salmon Carmacks First Nation and the Selkirk First Nation, Yukon Canada. Metallurgical testing completed by SGS Vancouver Metallurgy ("SGS") supports a simplified process consisting of froth flotation for the recovery of copper, gold and silver from both sulphide and oxide ores at Carmacks. These tests demonstrate outstanding recovery levels and concentrate grades in both the sulphide only and blended sulphide/oxide samples, which would be utilized by the mine.

Testing was done on samples consisting of material in which copper was present primarily in oxide minerals, where the copper was present as primarily sulphide minerals, and samples that were a blend of oxide and sulphide minerals. Test work produced a very clean, premium, high-grade concentrate that forms the metallurgical basis for the process flow sheet of the PEA, which the company expects to publish by the end of the current quarter. Flotation optimization and an economic evaluation of the target copper grade versus recovery has been recommended by SGS and will be considered in future test work.
