Lago Dourado Intercepts 1m of 30.7g/t and 1m of 22.6g/t Gold in Step-Out Hole, Increases Strike at Querosene Zone, Juruena Project, Brazil

TORONTO, ONTARIO--(Marketwire - Sept. 13, 2011) - Lago Dourado Minerals Ltd. (TSX VENTURE:LDM) (the "Company") announced that it has extended the known mineralisation at the recently discovered Querosene Zone at its Juruena Project, in Mato Grosso, Brazil. Hole JRND027 intercepted 1 metre of 30.7 g/t gold at a depth of 57 metres and 1 metre of 22.6 g/t gold at a depth of 66 metres in a step-out hole drilled 200 metres west of hole JRND022 which intercepted 2 metres of 47.1 g/t (see news release July 21, 2011). The strike length of the discrete, narrow, high-grade veins at the Querosene Zone now covers approximately 500 metres (see Figure A). Geophysical and gold soil geochemical anomalies continue 1.5 km to the west of hole JRND027 to the Crentes Zone and 2 km to the south of hole JRND018 to the Capixaba Zone that was drilled historically and returned similar narrow, high-grade intercepts including 3.7 m of 131.3 g/t gold.

Drill results received to date, which have been from zones on the edges of the giant geochemical footprint (the subcircular gold-in-soil anomaly at Juruena covers more than 10 sq km), have improved the geological understanding of the deposit. The metal association from multi-element analyses of drill core is Ag-Au to Au-Ag-Cu-Mo, with variable Bi, Te, Sb, Pb, Zn, suggesting a magmatic-hydrothermal system such as a porphyry to high-sulfidation mineral system or, potentially but less likely, an intrusion-related gold system. Variation in mineralization style from discrete high-grade Au-Ag quartz veins to zones of vein stockworks, disseminations, sheeted veins and breccias are consistent with this concept.

Drilling has now shifted away from the edges of the system and is focused more in the centre of the gold footprint with two rigs currently testing the Jacare's Field target (see Figure B). This target represents the largest and most consistent gold-in-soil anomaly (1 km x 1.4 km area averaging 180 ppb Au) outlined on the project to date. Further, this anomaly borders a major lithological contact zone, is coincident with a magnetic low, and is bounded by two magnetic highs.

"The positive drill results reported across multiple zones within the giant gold footprint at Juruena are very promising, particularly this early in the exploration program. We are optimistic that a better understanding of the geological model through the continuing Phase I drill program will lead us to the more mineralized zones in the system. We look forward to reporting further results as they are received," commented Forbes Gemmell, CEO.

Results for the remaining three of nine holes at Querosene are summarized below (results from the first six holes at Querosene are summarized in a press release issued July 21, 2011).

About the Company:

Lago Dourado Minerals Ltd. is a Canadian mineral exploration company focused on advancing its 100%-owned Juruena gold project in the state of Mato Grosso, Brazil. Extensive gold mineralization has been identified, and at least 0.5 million oz of gold has been mined from surface workings, over 10 square kilometres of the property. The Company has conducted systematic exploration programs over portions of the property and priority target areas are now being drill tested with a phase 1 drill campaign expected to continue through the fall of 2011. Large portions of the 70 sq. km property remain largely untested. The Company currently has 71.3 million shares outstanding.
