VANCOUVER, BRITISH COLUMBIA--(Marketwire - Sept. 23, 2011) - Dorato Resources Inc. ("Dorato" or the "Company") (TSX VENTURE:DRI)(OTCQX:DRIFF)(FRANKFURT:DO5) announces receipt, from Minera Afrodita, of final drill results from the first phase of drilling at the northern-most anomaly at Cobrecon. Results indicate the presence of a large and pervasive mineralized porphyry system, drill-tested over an area of 2km x 1km (Figure 1). Grades can be considered sub-economic at 0.1% to 0.2% copper, but the presence of such a large and pervasive mineralized system is encouraging for the two remaining drill targets (Cobrecon Sur and Cobrecon Este), which are defined by larger, more intense surface geochemical anomalies. Drilling on the remainder of the targets is subject to Minera Afrodita's permitting process.

Weak manufacturing data from China and a US economy deemed to have "significant downside risk," saw benchmark North American crude futures drop more than $5 to just above $80 a barrel, bringing the discount to international oil prices to more than $25. The biggest oil sands player, Suncor Energy (TSE.SU), tumbled 6.8% to C$26.21 on the Toronto Stock Exchange, bringing its year to date losses to more than 30%. Canadian heavy oil – all of which goes to the US – sells for $15 less than US crude, meaning oil sands developers have to deal with an effective oil price of $60-$70 a barrel that puts at risk many of the $100 billion of projects on the go in Alberta.
