Lago Dourado Provides Exploration Update On Its Juruena Project, Brazil

Lago Dourado Minerals Ltd. (TSX VENTURE:LDM), (the "Company") has received assay
results for an additional three diamond drill holes at the Arrastro Hills
porphyry target at its flagship 100%-owned Juruena Project located in Mato
Grosso, Brazil. Holes JRND066 and JRND067, drilled in the central part of
Arrastro Hills, and hole JRND068 (results have been received for the top 200m of
this hole), the first hole drilled at the Arrastro Hills South East target, did
not intercept any significant gold mineralization. Assay results for the
remaining two holes drilled at Arrastro Hills South East (JRND069 and JRND070)
are still pending. However, based on these initial drill results and the visual
core inspection of these remaining holes, it would suggest that the alteration
minerals and assemblages at Arrastro Hills and Arrastro Hills South East are a
result of an intrusive heat source that is distal to or non-related to an
underlying mineralized porphyry body. 


The Arrastro Hills Complex was identified as a potential mineralized porphyry
target based on the extensive clay-silica alteration, multi-element zonation,
alteration signature, variable intrusive rock types and magnetic and radiometric
characteristics. In total six reconnaissance-style diamond drill holes were
completed within the Arrastro Hills complex (see Figure A). The first three
holes (JRND065, JRND066 and JRND067) targeted soil values anomalous with
elements associated with the possible epithermal leakage in the central part of
the hills. The second three holes (JRND068, JRND069 and JRND070) were drilled in
the southeastern part of the hills to test an Au-Cu soil anomaly, strongly
brecciated and silicified volcanic rocks, interpreted magnetic heat source, and
a strong high temperature muscovite alteration signature identified from SWIR
analysis. The six drill holes intersected acid altered silicic volcanic rocks
including multiple zones containing dykes and breccia intervals, finely
disseminated sulfides and sulfide-filled fractures and vein. However, the lack
of gold mineralization and associated porphyry-related elements in the assays
received to date downgrade the probability of intersecting a mineralized
porphyry at a shallow to intermediate depth at the Arrastro Hills Complex. Based
on these results, the Company will shift its focus back to the multiple
high-grade gold zones previously discovered in the central part of Juruena.


Future Plans

Drilling at the project has been halted and exploration work will now focus on
advancing the known mineralized zones in the central part of Juruena in a cost
effective manner. Previous drilling from the central area of the project has
identified seven distinct mineralized zones with more than 20 intercepts with
greater than 50 gram-metres gold (see Figure B). The two high priority zones the
Company will initially focus on are the high-grade mineralized zones of
Querosene and Donna Maria. 


Querosene is a high-grade structure with more than 400 metres strike length that
has returned intervals of 4m @ 32.5 g/t Au and 2m @ 47.1 g/t Au. Only eight
shallow (less than 200m) diamond holes have been drilled at this zone. Donna
Maria is a high-grade structure adjacent to the Crentes Zone. Historic drilling
at Donna Maria returned 5.8m @ 52.4 g/t Au and 10.5m @ 14.6 g/t. The Company has
drilled only one diamond drill hole at Donna Maria which returned two intervals
of 1.0m @ 101.1 g/t Au and 16.0m @ 2.1g/t Au. Given the structural control of
both these zones, ground magnetics will likely be a useful and cost-effective
exploration tool to gain a clearer understanding of the underlying structures
that host the gold mineralization.


The Company also plans to advance the Novo Astro target to a drill ready status.
Novo Astro is host to an extensive set of active artisanal workings located
approximately 25km east-south-east along trend from Juruena. Detailed geological
mapping and extensive soil sampling of the area suggests that Novo Astro, whilst
related to intrusive activity, exhibits more classical lode-style controls to
mineralization. It is a gold-rich structurally-controlled system containing
distinct high-grade gold zones that have good strike continuity. The main
gold-in-soil anomaly is approximately 1 km wide and more than 2 km in strike
length. Rock chip samples have returned very high gold numbers, including 92.9
g/t Au, 34.5 g/t Au and 18.2g/t Au. In-fill soil sampling has been completed
over the higher priority areas identified during the recently completed
geological mapping work (assay results are pending). Once all the assays have
been received and have been integrated into the current dataset, any further
follow up work will be determined before specific drill ready targets can be
identified for future testing.

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 over 15 square
kilometres of the property, and at least 450,000 oz of gold has been mined from
surface workings. The Company has conducted systematic exploration programs over
portions of the property and priority target areas will be drill tested with a
Phase 2 drill campaign that is expected to be ongoing through 2013.
