Lago Dourado Discovers New Gold Zone; Intercepts 20 Metres of 1.28 g/t Gold and 4 Metres of 6.67 g/t Gold at Jacare's Field, Juruena Project, Brazil


TORONTO, ONTARIO--(Marketwire - Nov. 1, 2011) - Tuesday, November 1, 2011 – Lago Dourado Minerals Ltd. (TSX VENTURE:LDM), (the "Company") is pleased to announce that it has discovered a new gold zone, the Jacare's Field Zone, at its Juruena Project in Mato Grosso, Brazil. Results for the first eight holes drilled from two lines 400m apart at the previously untested Jacare's Field Zone are summarized in Table 1 below. Highlights include:

  • Hole JRND026 intercepted 48 metres of 0.70 g/t gold including 4 metres of 6.67 g/t gold (and 33.69 g/t silver);
  • Hole JRND034 intercepted 1 metre of 21.90 g/t gold (4.83 g/t silver) and 20 metres of 1.28 g/t gold including 1 metre of 12.60 g/t gold (39.54 g/t silver).

The Jacare's Field Zone is a 1km by 1.4km gold-in-soil anomaly (average 180 ppb gold) located 2km to the south of the previously drilled Crentes Zone and 2km south-west of the previously drilled Querosene Zone. All three zones cover an area of approximately 1.5km by 1.5km and are all located within the massive sub-circular gold-in-soil anomaly at Juruena that spans more than 10 sq km (see Figure A). Drilling to date at Jacare's Field has been concentrated across two separate drill lines, 400m apart with 100m between each drill hole (see Figure B), with the deepest mineralization encountered over 200m vertically below surface. The mineralized zone remains open in all directions and at depth.

Mineralization is contained within new host units (microgranite and porphyritic granite) not previously intersected at Crentes or Querosene. The mineralization style consists of broad zones of disseminated sulfides and fracture filling, zones of massive sulfides with high gold and silver grades and narrow zones of intense quartz – sericite – pyrite alteration containing good gold grades. Abundant magnetite was also intersected in numerous holes, indicating that rocks formed from an oxidised magmatic system; such systems are known to host large porphyry bodies elsewhere in the world.

The Company is approximately two-thirds of the way through its planned 15,000m Phase I campaign, with an estimated 20 holes still to be drilled. Both rigs continue to test the Jacare's Field Zone. Once this is complete, the drilling will be concentrated on the Uiliam Pit and the Tomate Zone. The Uiliam Pit was recently dewatered exposing a gossanous outcrop and broad zone (15-20m) of massive sulfide veins. The Tomate Zone is an extensive artisanal pit (250 metres long and up to 50 metres wide at its widest point) in the central part of the mineralized footprint. Two grab samples from Tomate, taken as part of the Company's October 2010 Technical Report, returned assays of >100 g/t Au and 30.4 g/t Au.

"Jacare's Field is an important discovery for the Company. Intercepting another different style of mineralization, this time within a different host environment, indicates that multiple mineralizing pulses have occurred at Juruena producing multiple gold zones over several hundred metres to kilometres in strike. This confirms our understanding of the potential for a major mineralized system to exist at Juruena," commented Forbes Gemmell, CEO.
