Lago Dourado Minerals Ltd. (TSX VENTURE:LDM), (the "Company") is pleased to
announce the remaining assay results for the recently completed
reconnaissance-style RC drill program completed on its flagship 100%-owned
Juruena Project located in Mato Grosso, Brazil. The 6,000 metre program was
successful in identifying two new near-surface highly mineralized zones that
returned gram-metre intercepts greater than 50 (Tomate and Mauro) and also
resulted in numerous encouraging intercepts with gram-metres greater than 20 at
an additional three zones (Donna Maria, Chico and Noventa Graus). Follow up
diamond drilling at these zones, as well as the central IP anomaly, is currently
underway through an 8,000 metre diamond drill program. Initial assay results
from this program are expected to be received in early 2013 (see Figure A for a
plan map of the project with highlight intercepts).

"We have been very pleased with the RC drill campaign. RC drilling has proven to
be a very cost-effective tool in exploring the giant gold-in-soil anomaly and
near-surface expressions of geophysical targets at Juruena. It was very
successful in identifying new mineralized zones and furthering our geological
understanding of the area. We now look forward to drilling deep diamond holes to
test the central IP anomaly as well as testing known existing zones at depth as
we look to demonstrate the overall system potential at Juruena," commented
Forbes Gemmell, CEO.
Highlights from the last set of assay results from the RC drill campaign include:
-- JRNRC089 drilled at the Tomate Zone intercepted 46 metres of 0.77g/t
gold from surface and ended in mineralization. This hole was drilled 240
metres to the north of hole JRNRC032 (see September 6, 2012 press
release) which returned 59 metres of 2.22g/t gold. Drilling at Tomate
has demonstrated a potential strike length of this zone of approximately
800 metres.
-- JRNRC081 intercepted 26 metres of 1.00g/t gold from surface at the Chico
Zone. This hole was drilled to follow up an intercept of 9.7 metres of
2.43g/t gold from auger drilling and the associated Au-Cu silica breccia
zone intersected in Phase 1 diamond drilling. The Chico target lies
directly along strike of Crentes on the Juruena Fault and is associated
with a circular and prominent magnetic low feature. The Au-Cu
mineralization at Chico is potentially related to the same Au-Cu
mineralized body at the eastern end of Crentes, 700 metres along strike.
-- JRNRC077 intercepted 25 metres of 1.01g/t gold at the northern end of
the Noventa Graus soil anomaly. This intercept provides the company with
significant upside to expand the mineral resource potential at Juruena
as it successfully proves the existence of potentially economic zones of
mineralization within the volcanic rocks in the south of the property
(Noventa Graus and South Mag). The source of the mineralization and its
relation to the known mineralized zones hosted in the granites to the
north is not yet known.
Tomate Zone
Step out holes from JRNRC032 (59 metres of 2.22g/t gold) all intercepted short
to broad zones of near-surface lower-grade mineralization. Highlight intercepts
from these holes include 46 metres of 0.77g/t gold and 31 metres of 0.66g/t
gold. The strike length of the Tomate Zone is approximately 800m and intersects
Crentes to the north while possibly terminating in the south at the Gleba Fault.
The Tomate Zone remains open at depth, with five of the 14 RC drill holes ending
in mineralization. Mineralization at Tomate is associated with a porphyry
intrusive unit (disseminated sulfides) and zones of intense hydrothermal
activity (fracture fill). The Tomate Zone is located on the eastern margins of
the central IP anomaly and was only previously intersected by hole JRND050 which
intersected narrower, but higher grade, mineralization (7.5 metres of 6.30g/t
gold).
Central IP Anomaly
Seven shallow holes (average depth of 70 metres) were drilled above the central
IP anomaly. None of these holes reached the depth of the IP anomaly and none
returned economic zones of mineralization however, highly anomalous zones of
Au-Cu-Mo mineralisation were intercepted. Deep diamond drilling to test whether
this mineralization is related to a porphyry intrusive body at depth, coincident
with the IP anomaly, is currently underway.
Noventa Graus
Four short holes were drilled at Noventa Graus as part of the RC drilling
program, with three of these drilled above or adjacent to South Mag, an ovoid
magnetic high that corresponds with multi-element geochemical anomalies. Two of
the three holes intersected a fine grain mafic intrusive unit while the third
intersected the breccia zone within the felsic volcanic rocks at the southern
margin of the South Mag anomaly. The fourth hole, JRNRC077, intersected a highly
mineralized zone of 25m @ 1.01g/t gold within the felsic volcanic rocks at the
northern end of the Noventa Graus gold-in-soil anomaly. The discovery of this
mineralization within a new host environment is particularly encouraging as it
provides further evidence there is potential for additional mineral resources
within the volcanic sequence in the southern part of the property (Noventa Graus
and South Mag).
Arrastro Hills
Nine RC holes were drilled to test the gold-in-soil, multi-element
(Bi-Ag-As-Hg-Mo-Pb-Sb-Zn) and IP anomalies at Arrastro Hills within a 3.5 x
1.5km ovoid-shaped target area. Drilling encountered multiple rock types,
consistent with a volcanic edifice that had been intruded by various intrusive
bodies causing the massive alteration footprint defined by the radiometric
survey and multi-element geochemistry. Whilst no significant mineralization was
encountered, drill chips confirm that the holes were drilled high in a large
hydrothermal system capable of hosting porphyry-epithermal related
mineralization. Diamond holes will be required to fully evaluate the deeper
porphyry-related mineralization potential at Arrastro Hills (see Figure B for an
interpreted geological model of Arrastro Hills).
