Dorato Receives Positive Results from Initial Metallurgical Testing
VANCOUVER, BRITISH COLUMBIA -- (Marketwire) -- 08/30/10 -- Dorato Resources Inc. (TSX VENTURE: DRI)(OTCQX: DRIFF)(FRANKFURT: DO5) ('Dorato' or the 'Company') is pleased to announce that it has received positive initial metallurgical results from Minera Afrodita for the Taricori Gold Zone within the Cordillera del Condor project in northwest Peru. Initial results suggest that greater than 90% of gold can be recovered via standard flotation techniques. The gold at Taricori appears to be sulphide free-milling, non-refractory mineralization. Dorato has a right to acquire 100% of Minera Afrodita.
Composite channel samples collected from underground adits were submitted for bench scale laboratory batch flotation analysis, and leach testing at SGS Laboratories in Santiago, Chile. The composite sample assayed as 11.86 g/t gold, 185 g/t silver, 8.01% zinc, 0.54% lead and 0.22% copper. Preliminary flotation test work was performed using three separate reagent formulas typical of conventional base metal flotation separation and was designed to separate copper-lead mineralization from the zinc mineralization.
Test work indicates that the mineralization separates relatively easily into a bulk rougher concentrate containing the copper and lead, and the majority of the gold and silver. The silver and gold recoveries to the rougher copper-lead concentrate range between 60% and 80% respectively in the preferred reagent (average gold recovery from 5 reagent tests is 83.5%). The zinc flotation recovered from the remaining mineralisation yielding recoveries of approximately 10% and 20% for gold and silver respectively; to the zinc concentrate (average gold recovery from 5 reagents was 14.0%). Together, in excess of 90% of the gold can be recovered via flotation from two concentrates. Critically, the gold at Taricori appears to be sulphide free-milling, non-refractory mineralization.
These early-stage results are extremely encouraging and indicate that gold mineralization is responsive to conventional metallurgical recovery techniques - results were sufficiently high that planned cyanide leaching tests of the tailing were cancelled (as less than 10% of the gold reported to the tails). At an appropriate stage, additional metallurgical testing will be ongoing in order to optimise the recovery process, and maximise the potential Net Smelter Return of any prospective future operations.
Cordillera del Condor Background
The Cordillera del Condor District has been one of the most important gold-bearing areas in Ecuador and Peru since pre-Incan times. On the Ecuador side of the border historical small-scale but high-grade gold production is reported to have exceeded 100,000 ozs. per year.
Modern exploration on the Ecuadorian side of the border has recently resulted in the discovery of multiple world-class gold and base metal-bearing deposits, such as Kinross Gold Corp's Fruta del Norte Gold deposit (inferred resources of 13.6 million contained ounces gold at 7.23 g/t gold), Corriente Resources Inc.'s Mirador Copper-Gold porphyry deposit (measured & indicated resources of 438 million tonnes at 0.61% copper, 0.19 g/t gold, and inferred resources of 235 million tonnes at 0.52% copper, 0.17 g/t gold) and the Mirador Norte Copper-Gold porphyry deposit (171 million indicated tonnes at 0.51% copper, 0.09 g/t gold plus 46 million inferred tonnes at 0.51% copper, 0.07 g/t gold), and Dynasty Metals & Mining Inc's Jerusalem Gold deposit in the Chinapintza district (measured & indicated resources of 0.58 million ounces gold at 12.4 g/t gold plus an inferred resource of 0.71 million ounces at 11.5 g/t gold). The technical information with respect to the above deposits was obtained through the respective company's public disclosure documents available on SEDAR.
