VANCOUVER, BRITISH COLUMBIA--(Marketwire - March 1, 2011) - Sunridge Gold Corp. (TSX VENTURE:SGC) is pleased to announce encouraging copper and zinc recovery results from recent metallurgical tests conducted on mineralized material from the Emba Derho deposit. The metallurgical work is part of the prefeasibility study currently being conducted on the Asmara North deposits located in Eritrea.
Emba Derho Deposit Metallurgical Tests
The results are from locked-cycle copper and zinc metal recovery testwork conducted at SGS (Vancouver) laboratory under the supervision of Blue Coast Metallurgy Ltd on samples from the Emba Derho deposit. Using a conventional, low-cost flotation flow sheet, the test results show a recovery of 92% of the copper producing a 28% copper concentrate and 88% recovery of the zinc producing a 62% zinc concentrate. Precious metal recoveries for gold and silver returned values of 50% and 55%, respectively. Head grades used in the test work were 1.15% copper, 2.14% zinc, 0.07 g/t gold and 5.1 g/t silver.
"These results show unexpected high copper and zinc recoveries from the Emba Derho mineralized material with impressive product grades," says Michael Hopley, Sunridge's President and CEO. "Considering the large amount of copper and zinc contained in the Emba Derho deposit this will certainly have a significant positive effect on the economics of the deposit in the ongoing prefeasibility study."
Sunridge is currently conducting metallurgical testing on the Emba Derho deposit as part of the current prefeasibility study on the Asmara North deposits. The program will include further flowsheet optimization, variability studies and testing of composites made from blending Emba Derho mineralization with that from two other VMS deposits on the Asmara Project, Adi Nefas and Debarwa.
Emba Derho Drill Program
Drilling with three drills has been underway at Emba Derho for the past two weeks as part of a planned 8,500 meter drill program. The first assay results are expected in 4 to 6 weeks.
