Dorato Resources Inc.: Polymetallic Mineralization Discovered at Lucero Target, Condor Gold-Copper Belt, NW Peru

(Source: MARKETWIRE)trackingDorato Resources Inc. ("Dorato" or the "Company") (TSX VENTURE: DRI)(FRANKFURT: DO5) is pleased to announce receipt of positive gold-silver and base metal geochemical results received from Minera Afrodita relating to the high priority Lucero geophysical target on the Condor Gold-Copper Belt project in northern Peru (previous News Release NR09-03).

Recent prospecting and sampling of the geophysical anomaly has returned highly anomalous results from 166 rock samples, ranging from below detection to 3.27 g/t gold, 171 g/t silver, 0.38% copper, 0.82% zinc and 1.24% lead. Interpretation of the results indicates that mineralization appears to be extremely pervasive through the country rocks representing a high priority target.

The Lucero target is located less than 5 kilometres to the south-east of the high-grade Taricori workings (previous News Release NR09-05), where grades from 168 vein channel samples averaged 10.95 g/t gold, 134.41 g/t silver, 0.21% copper, 3.99% zinc and 1.35% lead. The structural corridor, which intersects the Jerusalem Deposit (Dynasty Metals & Mining Inc.), Taricori Zone, and the Lucero Zone, appears to be a fundamental regional control on mineralization, extending for 11.5 kilometres through the Taricori Block (Figure 1).

Minera Afrodita's 2009 regional prospecting is in progress. Minera Afrodita has applied for a drill permit for the Taricori Zone, which is currently under review by the Peruvian authorities.

Lucero High-Priority Target Area

The Lucero Zone (Figure 1) is marked by coincident, pronounced magnetic and electromagnetic (conductive) anomalies developed on the eastern margin of a Jurassic tonalitic intrusion where sediments (red-beds and limestones) are structurally juxtaposed by faulting. The main geophysical anomaly (Figure 2) covers an area of approximately one square kilometre, but anomalous geochemistry is much more widespread.

Rock and stream sediment samples are routinely collected by Minera Afrodita during regional prospecting south-east of the Taricori target with a total of 166 rock samples taken in the area outlined (Figure 2). Coincident with the magnetic anomalies there are two distinct sample clusters, totalling 13 highly anomalous samples (red circles, Figure 2) - in this sub-set, gold ranges from 0.27 g/t gold to 3.27 g/t gold and averages 1.29 g/t gold, while copper ranges from less than 0.01% to 0.38%, averaging 0.12%. The average iron content in these 13 samples is 30.23%, reflecting the high concentrations of magnetite and pyrite in the mineralization.

Lucero Mineralization

Initial work suggests that mineralization is primarily developed in a sedimentary sequence where magnetite and pyrite appear to form replacement lenses and vein fill. The presence of magnetite accounts for the magnetic anomaly. Rock sampling indicates that gold and copper are the principal metals of importance in the system along with strongly anomalous bismuth and secondary zinc and lead.

In addition to the main mineralization in the sediments, a number of gold mineralized rock and soil samples have also been discovered in a tonalite body.

This mineralization has a similar geochemical signature to that found in the sedimentary rocks, but with no magnetite reported.

Lucero is interpreted to belong to the intrusion-related gold-copper deposits family. Globally, such a deposit setting is highly prospective for large bulk tonnage mineralization.
