Meridian has completed its initial round of crushing, grinding, gravity-separation and flotation testing with the results highlighting the simple flowsheet needed to mill Cabaçal's copper-gold mineralization. These preliminary results are from representative samples[1] drilled across the deposit (\"Figure 1\") and indicate significantly higher recoveries of copper and gold than those used in the historical resource calculation[2] but are in-line with those recorded from the Cabaçal Mine's four-year production history. The metallurgical program is ongoing and more results are pending.Highlights Reported TodayMeridian achieves high-grade 29% copper concentrate from Cabaçal met program;Meridian reports preliminary high recoveries of 94% for copper and 87% for gold at Cabaçal;Significantly higher metallurgical recoveries achieved to those used in the 2009 historical resource;Excellent metallurgy combined with robust grades of shallow copper-gold mineralization highlights open-pit potential at CabaçalCabaçal's copper-gold mineralization is liberated via a coarse grind of ~200 microns;Eco-friendly and simple flotation of Chalcopyrite via a frother and collection by Xanthate;Cleaner concentrates from partial regrind with lime addition to remove the gangue and depress pyrite;Representative concentrate samples to be made available for smelter performance analysis; andA Bond Work Index of 11.2 indicates medium soft rock as does the Abrasion Index of 0.28.Dr Adrian McArthur, CEO and President comments: \"These initial metallurgical results from Cabaçal's layers of copper-gold VMS mineralization are very consistent with the mine's historic ore production records and confirm that Cabaçal's mineralization responds very well to simple processing methods yielding clean concentrates with high grades of copper and gold via strong recoveries.
