Lago Dourado Intercepts 59 Metres of 2.22g/t Gold Including 1 Metre of 62.60g/t Gold from Surface at Juruena Project; Hole Ends in Mineralization

TORONTO, ONTARIO--(Marketwire - Sept. 6, 2012) - Lago Dourado Minerals Ltd. (TSX VENTURE:LDM), (the "Company") has intercepted a new near-surface intrusive body from its ongoing reconnaissance-style RC drill campaign at its flagship, 100%-owned Juruena Project located in Mato Grosso, Brazil. Hole JRNRC032, drilled 300m north of the Tomate pit, intercepted 59 metres of 2.22g/t gold from surface and ended in mineralization. Key points of note are outlined as follows:

  • Mineralization mostly consists of disseminated sulfides and is not vein controlled. Gold grade continuity throughout the hole was excellent (see Figure A for a Strip Log).

  • The mineralized zone is located on the southeastern edge of the central IP anomaly and along strike of the Tomate Zone (JRND050 intercepted 7.5 metres of 6.30g/t gold). The zone remains unconstrained to the east and 300 metres to the north and west (bounded by Crentes and Uiliam).

  • A narrow high-grade zone associated with a geological contact zone was intercepted at a depth of 43 metres (1 metre of 62.60g/t gold with visible gold - true width is unknown).

  • From 44 metres to 54 metres, the drill hole encountered a highly-altered intermediate porphyry dyke that averaged 2.91g/t over the 10 metres. The nature of mineralization is a positive indicator that this new zone could be continuous in strike, dip and grade.

Recent exploration results provide further support that Juruena belongs to a class of gold-rich porphyry systems. The geochemical and geophysical data suggest the main intrusive body associated with this system is located within the Crentes-Tomate-Mauro-Chico boundary as evidenced by the following (see Figure B for a visual summary):

  • Large (>1km x 1.5km), ovoid chargeability anomaly;

  • Associated 'porphyry' and 'epithermal' multi-element soil anomalies; and

  • Existence of multiple high-grade zones or 'offshoots' adjacent to the main IP anomaly (Crentes, Tomate and Mauro)

Follow up RC drilling is being conducted to the north and west of JRNRC032 to determine the size extent of this new mineralized intrusive body and its possible association to an interpreted larger mineralized porphyry body at depth beneath the central IP anomaly. The diamond rig is scheduled to recommence drilling in late September and will initially target the depth continuity of this zone.
