Lago Dourado Provides Exploration Update On Its Juruena Project, Brazil

Lago Dourado Minerals Ltd. (TSX VENTURE:LDM), (the "Company") is pleased to
provide an exploration update on its flagship 100%-owned Juruena Project located
in Mato Grosso, Brazil. Three drill holes have now been completed at the
previously untested Arrastro Hills porphyry-epithermal target. Assay results
have been received for the first drill hole while alteration analyses (SWIR
spectral analysis was conducted by the MDRU) from the first two drill holes and
also grab samples across the Arrastro Hills target area have also been received
and integrated with the soil sample data. 


Forbes Gemmell, President & CEO, said, "The results from the initial drilling at
Arrastro Hills and the SWIR study not only confirm the porphyry-epithermal
geological model for Arrastro Hills but also provides us with a much better
understanding of the zonation of the system. This zonation suggests that the
Arrastro Hills South East target is the higher temperature part of the system
which, in many porphyry systems, is located proximal to the porphyry centre. We
look forward to drill testing this new target in the coming weeks." 


The key takeaway points from the initial drill holes and the SWIR sample data
are outlined below and a schematic with the key geochemical and geophysical
data, alteration data and drill hole locations is provided in Figure A.




--  Geological logging, SWIR alteration analysis and assay results (where
    received) have confirmed that the Arrastro Hills alteration system
    represents a large porphyry intrusive complex as evidenced by the
    multiple intrusive types and zones of brecciation, the diversity and
    type of alteration minerals and the presence of disseminated sulfides.
    Most importantly, it has been confirmed that the underlying porphyry
    system is mineralized as evidenced by drill hole JRND065, the first hole
    drilled at Arrastro Hills, which intercepted 118m @ 3.0g/t Ag as well as
    anomalous levels of Pb and Zn. The presence of these co-incident mobile
    elements suggests the central part of Arrastro Hills, the focus of the
    first three drill holes, is an outflow area, either above or peripheral
    to the causative porphyry intrusive. 
    
--  An extensive alteration mineral study consisting of more than 230
    samples was recently completed by the MDRU. The study suggested that the
    Arrastro Hills South East porphyry target area is the most prospective
    target based on the presence of phengite, which is characteristic of a
    higher temperature part of the system that may represent an exposed part
    of a porphyry system. The study also found a strong association between
    phengite and gold mineralization at known mineralized zones elsewhere at
    Juruena, including the Crentes, Tomate and Uiliam zones. The types of
    alteration minerals (predominantly K-rich muscovite) in the central part
    of the Arrastro Hills are typical of an outflow region above or
    peripheral to a mineralised porphyry intrusion. This conclusion is also
    consistent with the anomalous Ag-Pb-Zn intercepted in JRND065 from this
    same area. 
    
--  The initial three diamond drill holes from the central part of Arrastro
    Hills all intercepted a thick homogeneous pile of volcanic units
    (minimum thickness of at least 250 metres). The top part of the volcanic
    sequence is represented by a silica cap whilst at depth the volcanic
    rocks were strongly brecciated, fractured, intensely altered and
    contained a variable amount of sulfides, the product of circulating
    sulfide-rich fluids from the underlying intrusive units. The thickness
    of the volcanic pile is encouraging as it provides an ideal host rock
    environment to trap mineral rich fluids above a gold-rich mineralized
    intrusive. Drilling also intercepted multiple intrusive bodies of
    varying composition from felsic to mafic, confirming the underlying
    magmatic activity was long lasting and dynamic in nature, the type of
    geological setting that is required to form a porphyry type deposit. 



Drilling Update

Three drill holes (JRND065, JRND066 & JRND067) from the central part of Arrastro
Hills have now been completed with assay results still pending for two of the
holes. Drill hole JRND068, the first diamond drill hole to test the new Arrastro
Hills South East target, commenced last week. As outlined above, the SWIR
analysis indicates Arrastro Hills South East may represent an exposed part of a
porphyry system. In addition, this target is also characterized by an intense
potassium radiometric anomaly, a major crosscutting fault structure, a deep
seated IP anomaly, an interpreted intrusive heat source from the airborne
magnetic survey and a centralised molybdenum soil anomaly that is wrapped on its
eastern fringe by a Cu-Au soil anomaly (see Figure A:
http://media3.marketwire.com/docs/ARRASTRO-HILLS-FigureA.jpg). 


Drilling year to date has been slower than expected due to access difficulties
associated with rain related damage to the main access road to the central part
of Arrastro Hills. Drilling productivity is expected to improve going forward
given the wet season typically ends in March and considering the Arrastro Hills
South East target is much more easily accessed from the Company's exploration
camp.
