Nifty Copper Mine

Project Quick Links


The Nifty Copper Mine is located on the western edge of the Great Sandy Desert in the north-eastern Pilbara region of Western Australia, approximately 350 km southeast of Port Hedland.


Nifty was initially discovered by WMC in 1981 and commenced operation in 1993 as an open pit oxide copper mine with processing via heap leaching and solvent extraction-electrowinning (“SX/EW”) recovery to produce copper cathodes. From 2006, it transitioned to an underground sulphide mine with processing via standard flotation to produce a copper concentrate at rates of over 50,000 tonnes of contained copper per year. Between commencement of the oxide operation and 26 November 2019, when the mine was placed onto care and maintenance (“C&M”), Nifty has produced more than 700,000 tonnes of copper metal.
Cyprium acquired 100% of the Nifty Copper Mine 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).


Over the past two years, Cyprium has invested significant time and resources to refurbish the Nifty SX-EW (solvent extraction and electrowinning) plant and build a comprehensive understanding of the open pit potential of Nifty’s sulphide orebody. Cyprium intends to re-start operations utilising a heap leach SX-EW to retreat the current heap leach pads, open pit oxide and transitional material. Concurrently, comprehensive metallurgical test work is expected to determine the optimal pathway to unlock value from the open pit sulphide material.


The Nifty Copper Mine has substantial existing infrastructure, including:

  • 2.8 Mtpa sulphide concentrator (in care and maintenance since November 2019)
  • 25ktpa copper cathode heap leach SX/EW facility (in care and maintenance since January 2009)
  • 21 MW gas turbine power station
  • Full heavy vehicle workshops and accommodation village
  • Fully sealed all-weather airstrip
