Bunda Creek

The tenement application is located about 470km SW of Katherine and covers an area of 619km². The area is crossed by the unsealed Buntine Highway and the Mistake Creek–Inverway Road.

The Company’s intention is to identify sedimentary-hosted copper and other base metal deposits within the applied area of the Birrindudu Basin. The targeted deposits are analogues to sedimentary copper deposits in the Central African Copperbelt, the Kupferscheifer district in Germany and Poland, and White Pine in Michigan.

Recently completed and ongoing work conducted by the NTGS and CSIRO on drill core from within the Birrindudu Basin, has highlighted its potential to host stratiform sedimentary copper deposits^1,2. This work has provided evidence that a copper source is present, that oxidised basinal fluids have leached copper from the basement geology, and that a suitable reductant is present in the lower part of the succession (Amos Knob Formation). This ongoing work is novel and highlights the Birrindudu Basin as a potential new frontier district for copper mineralisation.

Area selection was heavily influenced by 1:250,000 scale mapping conducted by the NTGS and insights provided by the ongoing CSIRO/NTGS project. EL34118 contains much of the Limbunya Group of the Birrindudu Basin. The Limbunya Group is the lower group of the stratigraphy and is known to contain a pyritic shale unit (Amos Knob formation). It is probable that this is the first reductant unit that would be encountered by circulating fertile fluids. The presence of evaporites within the succession also provides a ready source of salt for basinal brines to transport base metals³.
