The Maroochydore Copper Project is located in the Paterson region of Western Australia and approximately ~85km from Nifty. Maroochydore represents one of the largest existing greenfield copper exploration projects in Australia.
History
Maroochydore was initially discovered by Esso Australia Ltd in 1984. Since discovery, Maroochydore has had numerous owners and JV partners that have collectively drilled out the Resource and performed various metallurgical testwork regimes and studies on production scenarios. The primary copper sulphide mineralisation remains open along-strike and down-dip.
Cyprium acquired 100% of the Maroochydore Copper Project in March 2021, as part of a larger transaction with Metals X (CYM ASX Announcement – Transformational Acquisition of Highly Attractive Copper Portfolio, 10 February 2021).
Status
Cyprium intends to perform further drilling (testing along-strike and down-dip extensions) and detailed metallurgical testwork to unlock the potential of this significant copper deposit. Cyprium’s testwork program will be used to optimise the processing flowsheet.
Infrastructure
Maroochydore has an exploration camp with diesel powered generators and road access to the Nifty Copper Complex.

0.25% Cu cutoff. Metal grades take into account top and bottom cut. Numbers are rounded to reflect a suitable level of precision and may not sum due to rounding. The reported contained metal is not the same as a “recoverable” or “marketable” amount, as recovery rates and other factors can influence how much metal can be extracted.
