Ø Metallurgical testing demonstrates that Stage I (Antas North) is extremely amenable to conventional Froth Flotation for the beneficiation of the Copper sulphides.
Ø 97% Copper recovery was recorded in Rougher-Scavenger (R-S) stages.
Ø R-S Flotation performed very well at course grind sizes (up to 212µm) indicating that processing will not require intensive grinding.
Ø A common reagent suit was applied with typical consumption rates.
Ø A final concentrate of ~32.4% Copper was generated from Cleaner stage flotation which confirms ease and ability to produce saleable concentrates from Stage I.
Ø Interpretation of results provides confidence in predicting Overall Copper recoveries in excess of 90% for Antas North.
Ø These tests form part of a comprehensive metallurgical programme. Current results will be integrated into the Stage I Scoping Study.
Ø The high-grade Antas North Deposit is Avanco’s most advanced development target – Antas North SULPHIDE JORC Reported Mineral Resource stands at:
9.27M tonnes at 1.83% Copper and 0.44g/t Au for
169,000 tonnes of copper and 131,000Ozs of Gold
Ø Stage II (Pedra Branca) metallurgy is expected to be similar to Stage I. Historical test work has reported Stage II R-S recoveries between 92% and 95% Copper.
Ø The Company expects further resource growth at Pedra Branca,metallurgical testing of Stage II will commence and run concurrently with drilling during the 4th quarter.
Ø Stage I and II combined, JORC Reported Mineral Resource currently stands at:
661,000 tonnes of Copper and 572,000Oz of Gold
....and 142metres not included in JORC yet :)
