NEVADO RESOURCES CORPORATION (TSX VENTURE:VDO)(FRANKFURT:NSV) ("NEVADO" or the
"Company") is pleased to announce current Mineral Resource Estimates ("MRE") for
its Farrell-Taylor Vanadium-Titanium-Iron Deposit ("Farrell-Taylor") at the La
Blache Project, located some 140 km northwest of Baie-Comeau in the Upper North
Shore region of Quebec.
Results from the 45-hole / 16,467-metre helicopter-supported diamond drilling
campaign carried out by NEVADO in 2011 were used to model the Farrell-Taylor
massive oxide mineralization. The MRE for Farrell-Taylor were estimated by
Maxime Dupere, P. Geo., from SGS Canada Inc.-Geostat ("SGS-Geostat") of
Blainville, Quebec. Using a base case cut-off grade of 5.1% TiO2 Equivalent
("TiO2 Eq"), the MRE for Farrell-Taylor totals 101,700,000 tonnes grading 0.33%
V2O5, 18% TiO2 and 59.7% Fe2O3 (41.76% FeT) in the Inferred category. The
following table summarizes the MRE of Farrell-Taylor at other cut-off grades:

Notes:
The NEOMET process recovery is estimated to be 90% for both titanium and
vanadium, and 62% for iron. The estimates were based on an iron ore price of US
$120/tonne as Fe2O3, a titanium ore price of US $2,500/tonne as TiO2, and a
vanadium ore price of US $13,500/tonne as V2O5. Block model parameters are
appended.
(1) % TiO2 Eq denotes % TiO2 equivalent grade calculated as follows: %
TiO2 Eq = % TiO2 + ((% Fe2O3 x 62% x $120/tonne) / (90% x
$2,500/tonne) + (% V2O5 x 90% x $13,500/tonne) / 90% x $2,500/tonne).
(2) SGS-Geostat utilized a US $115/tonne mining-NEOMET-processing cost as
the base case: US $50/tonne mining + US $65/tonne processing cost,
including estimated G&A costs.
(3) US $150/tonne mining - NEOMET processing cost.
(4) US $420/tonne mining - NEOMET processing cost.
The MRE were performed in accordance with NI 43-101, Standards of Disclosure for
Mineral Projects, and the "CIM Standards on Mineral Resources and Reserves -
Definitions and Guidelines" developed by the CIM Standing Committee on Reserve
Definitions and adopted by the CIM Council on December 11, 2005. Mineral
resources, which are not mineral reserves, do not have demonstrated economic
viability. The MRE may be materially affected by environmental, permitting,
legal, title, taxation, socio-political, marketing, or other relevant issues.
The quantity and grade of the estimated Inferred resource reported herein are
uncertain, and there has been insufficient exploration to categorize them as an
Indicated or Measured resource. Further exploration may result (after validation
and resource update) in the reclassification of the Inferred mineral resource as
Indicated or Measured.
The mineralization consists mostly of magnetite (iron oxide) and ilmenite (iron
titanium oxide), with lesser amounts of iron-magnesium aluminum-silicate
minerals, all part of a series of sub-vertical, inclined and sub-horizontal
dykes, sills, veins, stockworks and disseminations emplaced along
multi-kilometric circular and elliptical configurations within the 35 km by 12
km La Blache Anorthositic Complex, such as the 45 km La Blache Ring of
Vanadium-Titanium-Iron.
The geological interpretations on section were linked together into a 3D mesh by
NEVADO. SGS-Geostat reviewed and validated the model and added some minor
modifications. The 3D mesh covers over 1,150 metres on the east-northeast
direction with an average width of 470 metres. The mineralization starts at 200
metres wide on the west-southwest and widens at depth to approximately 715
metres to the east-northeast. It dips 20 degrees towards the east-northeast, and
has a thickness of 70 metres on average, but ranging from 40 metres to as high
as 100 metres in the deeper portions. The technical parameters of the block
model are detailed below.
The database used for the resources estimation used a total of 45 diamond drill
holes totalling 16,467 metres (2010-2011 drill programs) and a total of 121,902
assays were considered in the validated database.
The assay method used was XRF for Iron and TiO2 and ICP AES with 4 acid
digestion especially for Vanadium in Val-d'Or at ALS Minerals of Vancouver.
Based on discussions among SGS-Geostat, the consultants and NEVADO, a
mining-processing cost of US $115 per tonne was used, which includes an
estimated US $50 per tonne for open pit mining and an estimated US $65 per tonne
for NEOMET (hydrometallurgical) processing (including G&A). Considering the
local resource potential and proximity to the nearby town of Baie-Comeau but
also the relatively large distance to smelters and larger mining communities,
SGS-Geostat considers the estimated mining and hydrometallurgical processing
costs to be adequate and conservative.
The overall % TiO2 Eq grade is defined as a temporary grade, which, when used
with the TiO2 recovery and TiO2 price, gives the correct net smelter return
royalty for a tonne of ore. This equivalent grade combined with TiO2 recovery
and TiO2 price can be used to calculate a marginal-processing cut-off grade for
resource modeling purposes. SGS-Geostat set the cut-off grade at 5.1% TiO2 Eq. A
sensitivity table was also prepared for several benches. All of the Inferred
mineral resource occurs between 0 and 600 metres vertical depth. A cut-off grade
of 5.1% TiO2 Eq was used for this table. No pit optimization (Whittle) was done
for the mineralization.

SGS-Geostat is expected to submit a National Instrument 43-101 technical report
for the Farrell-Taylor mineral resource within 45 days.
Michael Curtis, NEVADO's President and CEO, stated that: "NEVADO has achieved a
very significant milestone in the advancement of the La Blache Project by
identifying a 100+ million tonne massive oxide mineral resource at the
Farrell-Taylor Deposit with grade of 0.33% vanadium pentoxide, 18% titanium
oxide and 60% iron oxide, in one of the 18 major massive oxide lenses found at
La Blache since the first prospecting campaign in mid-2010. It is important to
add that several other occurrences have also returned strong results, which
further enhances the project's exploration potential. The Farrell-Taylor Mineral
Resources Estimates, now supported by the Stage 1 and Stage 2 metallurgical test
work, will enable NEVADO to begin one-tonne-per-day pilot plant testing in
Q3-2012."

Farrell-Taylor Block Model Parameters
-- Block modelling was done on the IO Solid and modified on the deeper
east-northeast portion by SGS-Geostat.
-- SGS-Geostat used composites of a regular length of 1.5 metres with a
minimum length of 0.75 metres. The 1.5-metre length was based on the
average length of the samples and the selected size of blocks.
-- The block model is entirely within NEVADO's mineral claims.
-- The geological model is open on all sides and can easily be extrapolated
to nearby western claims not owned by NEVADO.
-- The mineral claims are considered to be in good standing.
-- Coordinates used are in UTM NAD83 Zone 19.
-- The massive oxide mineralization was not cut by the topography.
-- There is no overburden contact surface; however, the block model was
designed according to overburden information from the diamond drill hole
core logs.
-- A specific gravity of 4.6 was used based on the weighted average of more
than 100 specific gravity measurements.
-- Inverse squared distance (1/d2) was used for the estimation.
-- The estimated resources were classified in accordance with National
Instrument 43-101 Standards and Policies, namely as Measured, Indicated
or Inferred resources, as applicable.
-- Classification was done according to drilling density, the continuity of
the available data and level of confidence in the data.
-- Currently, there are no Indicated or Measured resources.
-- SGS-Geostat modelled the massive oxide mineralization based on downhole
mineralized intersections within the mineralized solid.
-- Open pit mining was selected as the mining method, which influenced the
minimum mining and processing costs directly linked to the cut-off
grade.
