COPPER-GOLD-ZINC: Float, leach tests of Horne 5 ore positive

QUEBEC – Falco Resources of Montreal reports positive results from the preliminary metallurgical tests of material from the Horne 5 polymetallic deposit at Rouyn-Noranda. The tests were conducted by SGS Minerals at its Lakefield, ON, facility to characterize grinding parameters, gold liberation, flotation recovery base metals, and cyanidation recovery gold and silver.

A flowsheet with grinding, open circuit sequential flotation and concentrate leaching was chosen. Tests were conducted on two composite samples with average head grades of 0.32% and 0.19% Cu. One sample (M1/2) was a high copper-low zinc material, and the other was low copper-high zinc.

“We are very encouraged by the initial results. Overall these results indicate that the Horne 5 deposit is amenable to flotation and leaching resulting in strong recoveries for all four metals,” commented Luc Lessard, Falco president & CEO.

In 2014 the maiden resource estimate for the Horne 5 deposit was 25.4 million inferred tonnes grading 2.64 g/t Au, 023% Cu and 0.7% Zn or 2.2 million oz of contained gold.
