Navarre Minerals Limited announced that it has received notification from the Queensland Government of the final approval for an amendment to Mt Carlton's Environmental Authority which allows for the commencement of mining operations at the Mt Carlton United (MCU) gold-silver-copper deposit. The MCU deposit is located approximately four kilometres from the Mt Carlton mill. This approval clears the last key regulatory requirement for advancement of MCU, with first ore from the project expected to be delivered to the Mt Carlton processing facility in December 2022.

The MCU project is one of five potential satellite open pit deposits identified within the tenement package included in Navarre's acquisition of the Mt Carlton operation. Since acquiring Mt Carlton, Navarre's commitment to investment in resource definition and exploration drilling has resulted in significant growth of the Mt Carlton mineral inventory, particularly for MCU.
