Euro Sun Announces Comprehensive Metallurgical Test Results Euro Sun Announces Comprehensive Metallurgical Test Results for the Rovina Valley Project in Romania 81.5% GOLD AND 88.6% COPPER AT COLNIC PIT 73.2% GOLD AND 94.7% COPPER AT ROVINA PIT TORONTO, Sept. 19, 2018 (GLOBE NEWSWIRE) -- Euro Sun Mining Inc. (TSX: ESM) (Euro Sun or the Company) is pleased to announce the results of the comprehensive metallurgical pilot plant test program conducted by Eriez Manufacturing at their test facility in the United States. Figure 1 (Colnic Pit) Figure 2 (Colnic Pit) Figure 3 (Rovina Pit) Bulk samples consisting of approximately 3,000 kg per sample; representing the main geometallurgical domains from the Colnic pit and the Rovina pit were selected under the guidance of SRK Consulting. Samples were then stage crushed, ground and subjected to column rougher/scavenger flotation. The primary grind for samples Met 42 and Met 44 (Colnic) was 80% passing 75 microns. The primary grind for sample Met 43 (Rovina) was 80% passing 53 microns. The rougher scavenger concentrate was then re-ground to 80% passing 13.8 microns and cleaned in a column cleaner circuit to produce the final concentrate. The rougher/scavenger concentrate samples for Met 42 and Met 44 were cleaned using a 3-stage closed circuit column arrangement. Rougher/scavenger concentrate from sample Met 43 was cleaned using a 2-stage open circuit column arrangement. The results delivered an average gold recovery at the Colnic pit of 81.5% and Copper recoveries of 88.6% while the average gold recovery of the Rovina Pit was 73.2% and Copper recoveries averaged 94.7%, all utilizing no cyanide anywhere in the flotation circuit. Scott Moore, Euro Suns CEO states, We are very pleased to see the results of the Eriez test work. The gold and copper recoveries as well as the final concentrate copper grades confirm the excellent results seen in smaller scale testing conducted in April 2017 and now re-produced in a feasibility level test program.
