Pilot Gold Releases Metallurgical Results from Valley Porphyry

Pilot Gold Inc. (TSX:PLG) released metallurgical results from the Valley porphyry at its TV Tower project. The program was aimed at testing the mineralization’s amenability to producing gold and copper concentrates.
As quoted in the press release:

The test work used the same flowsheet developed for the Halilaga deposit with minor adjustments for reagents, flotation times, regrind size and number of stages of cleaning.  These results are from open-cycle laboratory batch tests.  Process parameter optimization and locked-cycle testing have the potential to improve copper and gold recoveries at a modest reduction in concentrate grades.
Overall, these results indicate that the Valley porphyry is amenable to flotation producing a concentrate with strong recoveries and grades in both copper and gold. The metallurgical flow sheet used suggests that mineralized material from the Valley Porphyry can be processed through a mill designed to process ore from Halilaga.  Mineralogical examinations of the two composites showed that pyrite is the major sulphide mineral with lesser or subordinate amounts of chalcopyrite, bornite, chalcocite and traces of covellite.

Matt Lennox-King, president and CEO of Pilot, commented:

Metallurgical testing is a key factor in demonstrating a path forward at the Valley zone. These initial results demonstrate that the Valley porphyry could potentially be a satellite to our 40% owned Halilaga copper-gold project, 15 kilometres to the east.
