Strandline Resources Limited (ASX: STA) continues to receive successful results from testwork at its 100% owned Mt Gunson Copper Project located 130km north of Port Augusta in South Australia (Figure 1).
Figure 1. Location of Mt Gunson Copper Project
As part of a Pre-Feasibility Study being funded by Torrens Mining Limited, a series of bench top metallurgical tests to examine the viability of sodium cyanide leaching of the copper have been completed. The results demonstrate that about 70% to 75% of the copper in the Windabout deposit and 85% to 90% of the copper in the MG14 deposit was readily leached by cyanide into solution.
In addition, a preliminary program of float testwork on the residues from the leach has shown that a significant proportion of the remaining copper can be floated into a concentrate.
In summary, overall copper recoveries of more than 90% may be achievable by the combined leach-float process.
The copper recoveries represent a dramatic improvement from previous testwork that applied a conventional sulphide flotation test and achieved recoveries of 54% to 68%.
Torrens Mining is expecting to complete its Pre-Feasibility Study over the coming months with a transition into a Bankable Feasibility Study by mid-year.
