Lago Dourado Discovers New Gold Zone: Intercepts 13 Metres of 4.00g/t Gold and 57 Metres of 1.52g/t Gold From Surface at Mauro, Juruena Project, Brazil

TORONTO, ONTARIO--(Marketwire - Aug. 28, 2012) - Lago Dourado Minerals Ltd. (TSX VENTURE:LDM) (the "Company") has discovered a new mineralized zone from its ongoing reconnaissance-style RC drill campaign at its flagship, 100%-owned Juruena Project located in Mato Grosso, Brazil. The discovery of the Mauro Zone is particularly encouraging due to the presence near-surface of higher grade mineralization within a lower grade halo. The Mauro Zone is located adjacent to the new major porphyry target identified in the recently completed IP survey and is proximal to the Uiliam zone, where Hole JRND046 intercepted 216 metres of 0.55g/t gold (see Figure A). Assay highlights from this zone include:

  • Hole JRNRC014 intercepted 57 metres of 1.52 g/t gold from surface including 1 metre of 60.70 g/t gold;

  • Hole JRNRC010 intercepted 13 metres of 4.00 g/t gold including 2 metres of 20.90 g/t gold;

  • Hole JRNRC011 intercepted 22 metres of 1.11g/t gold from surface including 1 metre of 16.30g/t gold.

"The existence of higher grade mineralization close to surface has positive implications for the resource potential of the Mauro Zone and also adds another zone to the potential resource base being systematically compiled by our exploration team. We look forward to receiving additional RC results of the main porphyry targets as well as to the deeper testing of these targets with the recommencement of diamond drilling in September," commented Forbes Gemmell, CEO.

High-grade near-surface mineralization at Mauro is predominantly associated with supergene enrichment but also includes primary mineralization within the host rock. The mineralized zone at Mauro has been identified over an area of 300 metres by 150 metres with ten of the 11 holes drilled at this zone intersecting gold mineralization and with three holes ending in mineralization (see Figure B). The zone remains largely untested and there is excellent exploration potential given the gold-in-soil anomaly that led to the identification of the Mauro Zone continues approximately 500 metres to the north and 500 metres to the south.

Arrastro Target

Drill hole JRNRC007 at Arrastro Sul, a new and previously untested zone adjacent to the south of the Arrastro Hills Porphyry complex, intercepted 65 metres of 0.21g/t gold near-surface and 22 metres of 0.46g/t gold at the bottom of the hole. The hole was mineralized throughout. Its close proximity to the Arrastro Hills porphyry system indicates that this large system (5km by 2.5km) is highly likely to contain multiple mineralized bodies. Arrastro Sul consists of a large Au-Mo-Cu soil anomaly that corresponds with an ovoid magnetic feature (+600m) which is intersected by the main Juruena Fault. Mineralization consists of finely disseminated sulfides within a moderately altered, fine grained mafic intrusive rock with an intensely altered, fine grained felsic intrusive unit encountered towards the bottom of the hole where higher gold grades were reported.

Five RC holes were drilled at the Arrastro SE porphyry target with only JRNRC004 intercepting gold mineralization (3 metres of 0.75g/t gold and 1 metre of 3.61g/t gold). All holes were drilled prior to the completion of the IP survey and were drilled outside the zone that demonstrated the strongest chargeability anomaly. Hole JRNRC004 was the closest hole to the IP anomaly (100m away) and gold mineralization in the hole was associated with sulfide veinlets, a positive indicator that the IP anomaly lies on mineralization. Follow up RC holes have been designed to test the four main IP anomalies at Arrastro Hills and will be completed in the coming weeks.
