Saracen Mineral Holdings Limited owns 100% of the Carosue Dam Operations (CDO) through its wholly owned subsidiary Saracen Gold Mines Pty Ltd.
Summary:
The deposit itself is lithologically and structurally controlled and sits within an altered volcaniclastic sandstone unit that has been offset along a series of major faults running NE-SW and NW-SE, as well as intruded by large lamprophyre units post mineralization. Mineralization is dominated by pyrite and hosted in broad hematite altered sandstone units with a central high grade siliceous core light-moderately dipping to the North.
Summary:
Current mining methods employed at Carosue Dam Operations utilize long hole open stoping.
Processing Technologies
- Gravity separation
- Leaching plant
- Carbon in leach (CIL)
- Cyanide (reagent)
Summary:
The ore reserve will be treated at the established Carosue Dam processing facility. The Carosue Dam Process Plant is a CIL cyanide leach plant incorporating a gravity circuit which is appropriate for the extraction of gold from free milling gold ores.
The Carosue Dam processing plant continued to perform above name plate capacity during FY2017, with a total of 2,469,000 tonnes of ore milled. Red October, Deep South and Karari were the predominant ore sources with supplement mill feed from lower grade stockpiles.
