Overview

• New South Wales has a copper endowment (past production and identified resources) exceeding 20.3 million tonnes.

• Copper is either the principal commodity or a significant credit in a diverse range of deposits.

• The state remains under-explored, with a range of opportunities for new discoveries.

Deposit types

New South Wales (NSW) has a diverse range of copper-rich deposits where copper is produced as either the principal commodity (e.g. Northparkes, CSA, Tritton) or as a concentrate with significant copper credits. These copper-enriched systems include:

• Porphyry Cu–Au deposits and related skarn deposits, including the world class Cadia Au–Cu system (Cadia East and Ridgeway mines) and the Northparkes, Copper Hill and Temora Cu–Au districts

• Copper-rich volcanic associated massive sulfide (VAMS) deposits hosted by deep marine basins, including the world class Woodlawn Kuroko-style deposit and the deposits in the Tritton–Girilambone Besshi-style district (Tritton operations)

• Orogenic base-metal deposits including the ‘Cobar’-type Cu-dominant (CSA) and Au–Cu (The Peak) mines, with a distinctive feature of many such deposits being the vertical extent and continuity of individual ore lenses

• High and intermediate sulfidation epithermal Au–Cu systems such as Peak Hill and Mineral Hill — some of which are associated with copper-rich porphyry systems

• Significant copper in some Broken Hill-type base metal deposits (Pinnacles — Curnamona Craton) and in a number of intrusion-related polymetallic systems (Conrad).

Lachlan Orogen

The mainly Ordovician to Carboniferous Lachlan Orogen is, in general, poorly explored for copper. Recent exploration has focussed on the large to very large porphyry Cu–Au systems associated with the Macquarie Arc — several belts of volcanic-dominated rocks of Ordovician to Early Silurian age which host the world class Cadia deposits. In addition, the Lachlan Orogen contains many small to large copper-rich deposits associated with Ordovician and Silurian back-arc basins (VAMS-type deposits) and the late Silurian to Early Devonian Cobar Basin (‘Cobar-type’ orogenic sulfide-rich Cu ± Au deposits — e.g. CSA). Other targets include:

• Cu-rich skarns, high and intermediate sulfidation epithermal deposits

• orogenic sulfide-rich deposits associated with major structures — some of which have been major producers in the past and

• Devonian-age intrusion-related copper-rich systems associated with units of the Boggy Plain Supersuite (e.g. the Yeoval porphyry Cu deposit).

New England Orogen

The Devonian to Triassic New England Orogen is under-explored by Australian standards. The orogen is host to copper-rich volcanic associated massive sulfide deposits and polymetallic intrusion-related deposits, some of which also contain significant copper. There are also a number of poorly explored porphyry Cu–Au–Mo systems of Permo–Triassic age.

Other areas

There is further significant potential for copper-rich deposits in the following areas:

• The northern extension of the Lachlan Orogen — where it is covered by younger sequences (potential for porphyry Cu–Au and ‘Cobar-type’ orogenic sulfide-rich deposits)

• The Neoproterozoic to early Palaeozoic Koonenberry Belt (now interpreted to be a Cambrian Arc built on the rifted margin of Gondwana), which hosts VAMS-type mineralisation including the Grasmere deposit

• Along the edge of the Palaeoproterozoic Broken Hill Block, where there is untested potential for porphyry Cu–Au mineralisation.
