Overview

Halls Creek copper project is situated 25km southwest of Halls Creek in Western Australia’s Kimberley region and covers part of the Halls Creek Mobile Zone which is highly prospective for a range of commodities including copper, gold, and nickel.

The project includes the Mount Angelo North copper-zinc deposit, an extensive zone of near surface oxidised Cu-Zn mineralisation overlying massive Cu-Zn sulphide mineralisation.

Mineral Resources are reported in accordance with the JORC Code 2012, the Mount Angelo North mineral resource estimate is reported as 1.72Mt @ 1.4% Cu, 1.4% Zn, 12.3ppm Ag (using 0.4% Cu lower cut) for 23,000 tonnes copper, 25,000 tonnes zinc, 680,000 ounces of silver.

The Bommie Porphyry Copper mineral resource estimate is reported as 95.6Mt @ 0.27% Cu for 262,000 tonnes copper metal (using 0.2% Cu lower cut) and includes 16Mt @ 0.3% Cu of indicated material for 48,000 tonnes copper metal.

AuKing Scoping Study

In December 2022, a Memorandum of Understanding (MoU)¹ was signed between Cazaly and AuKing Mining (ASX: AKN) to include the Company’s Halls Creek Copper deposits, Mt Angelo North and Bommie deposits, in a mine scoping study to be conducted by AuKing.

The study determined the potential viability of open pit and underground operations centred around AuKing’s Sandiego Cu-Zn-Ag deposit which lies 10km north of Mt Angelo North.

In June 2023, AuKing released its positive findings from the scoping study² which confirmed the potential for a financially robust, globally competitive open pit and underground operations centred around the Sandiego deposit.

Based on the study outcomes,  the combined Halls Creek and Koongie Park Copper deposits will now move towards potential development.

In addition, AuKing Board has approved the commencement of further studies for the project with forward work plan for next stage studies currently being finalised.
