Granite Creek Copper Ltd. announced the preliminary results of a metallurgical study designed to increase recovery of copper from oxide material at its Carmacks Copper-Gold-Silver project ("Carmacks Project" or the "Project") Kemetco Research Inc. ("Kemetco") has been contracted to carry out an initial series of scoping tests to evaluate the potential for extraction and recovery of copper from unrecovered copper oxide minerals in Carmacks Project flotation tailings as referenced in the Company's 2023 Preliminary Economic Assessment ("2023 PEA"). Testing involves the leaching of tailings from previous flotation testing of oxidised copper material to resolve copper into solution and subsequently precipitate copper in a form that could be added to a concentrate being produced by sulphide flotation. The leaching portion of the test work has now been completed with up to 81% of the copper present in the test samples going into solution.

The remaining project task, currently underway at Kemetco, is to complete a series of bench tests to evaluate methods for selective recovery of the leaching copper from solution.
