                  RESOURCES INCREASED TO OVER 80 Mlbs of U3O8 
                              at a 200 ppm cut-off 
 
Berkeley Resources Limited is pleased to advise the completion of the initial 
Mineral Resource Estimates, reported in accordance with the JORC Code (2004), 
for the Salamanca Uranium Project in Spain.  New estimates for the Alameda and 
Villar Area deposits have increased total Mineral Resources within Berkeley's 
projects by 53% to over 80 Mlbs of U3O8 at a 200 ppm cut-off and over 100 Mlbs 
at a 100 ppm cut-off (see Table 1). 
·    Mineral Resources within Berkeley's projects now total 81.2 million tonnes 
at 450 ppm for 80.4 Mlbs U3O8, with 32% in the Measured and Indicated 
categories. 
·    Mineral Resources for the Alameda South Deposit total 18.5 Mlbs at an 
average grade of 458 ppm U3O8 including 49% Indicated Resources. 
·    Mineral Resources for the Alameda North Deposits total 4.5 Mlbs at an 
average grade of 503 ppm U3O8. These Mineral Resources are all in the Inferred 
category. 
·    Mineral Resources for the Villar Deposit (previously Esperanza) total 4.9 
Mlbs at an average grade of 446 ppm U3O8. These Mineral Resources are all in the 
Inferred category. 
·    Reverse circulation (RC) drilling to upgrade and extend the Mineral 
Resources at Palacios North, Sageras and Alameda South is due to commence in the 
June Quarter with updated Mineral Resource Estimates for these deposits 
completed thereafter.

Ian Stalker, Berkeley Resources MD commented "These latest figures confirm the 
quality of the Salamanca resources allowing us to push forward on our 
Feasibility Study to bring the Project back into production and to develop a 
production profile commensurate with such a quality resource base.  The 
substantial resources available encourage us to investigate increasing 
production beyond the present plant capacity of 2.1 Mlbs U3O8 per annum. 
The 200 ppm cut-off applied to the Mineral Resource Estimates (Table 2) is a 
conservative approach and along with increasing mining production and 
throughput, offers the potential to improve operating costs from previous 
estimates."

1.  MINERAL RESOURCE INVENTORY 
 
Berkeley's Mineral Resources are located in 5 areas:  Águila, Alameda, Villar, 
Retortillo and Gambuta. 
Berkeley has previously advised Mineral Resource Estimates for the Retortillo, 
Águila and Gambuta Areas. Following the completion of the confirmatory drilling 
program at the Alameda Area (announced on the 18th March, 2010), Mineral 
Resource Estimates for the Alameda South, Alameda North and Villar deposits have 
now been completed. A detailed breakdown of each deposit is presented in Table 
2. 
Berkeley's Feasibility Study is focussed initially on the Águila and Alameda 
areas, with possible extension to the Retortillo and Villar areas. These four 
areas form the Salamanca Uranium Project (the "Project").

2.  SALAMANCA URANIUM PROJECT 
 
Berkeley's Feasibility Study process for the Salamanca Uranium Project commenced 
in May 2009, following Cabinet approval of the Co-Operation Agreement between 
Berkeley and ENUSA.  The Study objective is to assess the viability of 
restarting mining within the Salamanca State Reserves, based on a number of 
known uranium deposits. 
Following successful completion of the Scoping Study, announced in December 
2009, the Company has focused on the estimation of Mineral Resources based on 
historical exploration targets, as well as acquiring representative samples for 
a comprehensive program of metallurgical testing. This process has now been 
completed for the Águila Area, proximal to the Quercus processing plant and the 
Alameda Area, 12km to the west. Final Mineral Resource Estimates for the 
Feasibility Study, which are intended to upgrade resource categories, will be 
available later in 2010 after infill RC drilling and probing of additional ENUSA 
holes. 
2.1  Geology 
The largest accumulations of uranium within the Project area are hosted in an 
Upper Proterozoic to Lower Cambrian package of rocks called the Schist Greywacke 
Complex (SGC). The SGC and associated Hercynian granitic plutons form the 
basement which is unconformably overlain by continental sediments deposited 
during the Tertiary Alpine Orogeny. The cover sediments are unmineralised, but 
uranium mineralisation does occur within intragranitic veins. 
The SGC is affected by the 3 main phases of the Hercynian Orogeny and pre 
Hercynian deformation has also been recognised. Later Alpine movements 
rejuvenated earlier Hercynian structures as well as developing new fracture and 
breccia zones. 
The complex was metamorphosed to lower green schist facies during the Hercynian, 
and well developed contact aureoles and small granitic dykes and sills are 
common around granite margins. 
The deposits are associated with quartz sericite metapelites which are often 
carbonaceous. Structural preparation and rock competencies appear to have 
influenced deposit formation.  The official International Atomic Energy 
Association classification for the metasedimentary hosted deposits is Vein Type 
- Sub Type Iberian, originally formed by low temperature near surface 
hydrothermal processes. Variable local weathering effects influence the 
distribution of mineralisation, the degree of which varies between deposits. 
Disequilibrium has not been identified as a significant issue. 
2.2  Alameda Area 
The Alameda South and North deposits are located approximately 14km to the west 
of the Quercus Plant and have a combined total Mineral Resource Estimate of 22.5 
Mt at 466 ppm for 23.1 Mlbs U3O8. 
Alameda South 
The Alameda South deposit was discovered in the 1960's and subsequently drilled 
out on a 50m x 50m pattern using diamond drilling with chemical assays. The 
deposit extends from the surface down to 120m and covers and an area of 2km by 
1.2km with relatively flat surface topography. Total Mineral Resources have been 
estimated at 18.4 Mt at 458 ppm for 18.5 Mlbs U3O8, including 49% in the 
Indicated category. 
The historical drill hole database for the Alameda South deposit contains 400 
diamond drill holes for a total of 40,000m.  The drill spacing is 50m x 50m over 
the majority of the deposit although this has been reduced to 35m x 35m over the 
main central zone of mineralisation.  All of the historical assay data consists 
of chemical assays which have been checked against the historical drill logs. 
Berkeley has completed a confirmatory diamond drilling program consisting of 19 
holes in a series of traverses across the deposit.  The detailed results were 
recently announced (18th March, 2010) with all of the Berkeley holes 
intersecting mineralisation consistent with the historical data.  The e-grades 
from the Berkeley drill holes were combined with the historical chemical assay 
data for use in the estimate. 
Uranium mineralisation at Alameda South is hosted by a deformed sequence of 
regionally and thermally metamorphosed quartz sericite pelites. In addition, 
granitic sills and shallow dipping dykes were intruded after the main folding 
and metamorphism events followed by the uranium mineralisation. 
Uranium mineralisation occurs in a complex network of moderately to steeply 
dipping brittle structures (veins, faults, fractures and along bedding contacts) 
as a result of a low temperature hydrothermal event.  The mineralised zones 
commonly have sharp boundaries, separating mineralised structures from poorly 
mineralised host rock, recent fracturing is partly responsible for this. 
Mineralised domains are 50-200m wide in plan trend North and North-West and dip 
moderately-to-steeply West and South-West respectively.  The North-trending 
domain has a strike extent of approximately 800m and the North-West-trending 
domains have a cumulative strike of approximately 1,500m.  Within each of the 
domains, multiple mineralised zones have widths of up to 50m.  The depth to the 
base of mineralisation varies depending on how well developed the structures are 
that host the mineralisation.  In the North-trending part of the deposit which 
has a fault zone in the footwall, the mineralisation extends up to 120m below 
surface.  Elsewhere on the North-West-trending mineralised structures the 
mineralisation extends 60-70m below surface. 
Berkeley's geological model is based on a broad outer envelope of mineralisation 
that captures the majority of the +100 ppm U3O8 grades.  It includes internal 
sub grade material in order to maintain geological continuity across drill 
sections. 
Average bulk density values, derived from Berkeley drill core, were assigned to 
oxidised, transition and fresh blocks in the model. 
The Mineral Resource Estimate was undertaken by AMC Consultants (UK) using a 
block model configuration of 10m x 10m x 6m parent cells, with cells being 
permitted to split once in any direction where bounding surfaces are 
encountered. 
Sample uranium grade statistics were calculated and population characteristics 
analysed for each of the mineralised zones. High grade top cuts were determined 
for each zone and applied to the sample composites to reduce the affect of 
extreme outlier values. Variographic analysis was successfully completed for two 
mineralised zones and parameters were derived using multi-structure spherical 
models. Uranium grades were estimated from 2m sample composites, using Ordinary 
Kriging for the two mineralised zones and inverse distance squared weighting for 
the remaining zones. Grade interpolation into parent cells was conducted under 
hard-bounded zonal control, using mostly 40m x 40m x 5m search ellipsoids 
aligned in the average plane orientation of each zone. 
The Mineral Resource classification was based on confidence levels for criteria 
such as data density and interpreted grade continuity. Indicated Resources were 
restricted to estimated blocks within the central part of the deposit where the 
drilling density is 35m x 35m (or less) and the grade continuity is very good. 
An Inferred category was assigned to those blocks where the drilling density was 
50m x 50m or greater. 
The Mineral Resource Estimates in Table 2 are all reported using a 200 ppm U3O8 
cut-off grade.  However, the Scoping Study pit optimisation study indicated that 
a cut-off grade closer to 150 ppm should be considered.  The impact of assuming 
various cut-off grades at Alameda South is illustrated in Table 3 below.

A 30 hole RC drilling program to commence in the June Quarter is planned to test 
the lateral and depth potential identified in the recent diamond drill program 
and to increase confidence in areas previously drilled at lower density.  It is 
anticipated that the majority of the Inferred Resource will be upgraded 
following this program and an updated resource statement will be announced at 
the end of the June quarter. 
 
Alameda North 
The Alameda North deposits consist of 3 separate zones extending north from 
Alameda South over a distance of 3.5 km along the granite contact.   All of the 
Mineral Resources have been classified as Inferred and total 4.1 Mt at 503 ppm 
for 4.5 Mlbs U3O8.  A breakdown of the individual deposits showing the number of 
holes drilled is included in Table 4.

The historical drill hole database for the Alameda North deposits contains 274 
diamond drill holes for a total of 16,000m (see Table 4).  The drill spacing at 
all 3 deposits is approximately 35m x 35m and all of the historical assay data 
consists of chemical assays. The mineralisation has been interpreted within an 
envelope of +100 ppm U3O8 although sub grade material has been included in order 
to maintain geological continuity across drill sections.  A block model with a 
cell size of 10m x 10m x 5m (vertical) was constructed with original chemical 
assay data composited to 2m after applying a top cut of 5,000 ppm U3O8 to reduce 
the effect of extreme outlier values. Blocks were estimated using Ordinary 
Kriging with a minimum of 5 samples required to interpolate a grade into a 
block.  An average bulk density of 2.7 was used based on the Berkeley density 
measurements taken at Alameda South. 
The Mineral Resource Estimate was classified as Inferred as Berkeley has not 
done any confirmatory drilling in this area.  However, all of the historical 
drilling was undertaken at the same time as the Alameda South historical 
drilling where Berkeley has completed the confirmatory diamond drill program. 
 
2.3  Villar Area 
The Villar Area is located 10km north of Alameda and 14km north-west of the 
Quercus Plant.  The Area has been extensively explored since the 1960's but 
still contains a number of untested radiometric anomalies.  A small historical 
underground mine was developed at the Villar Deposit but only limited mining 
activity was undertaken. 
Berkeley airborne radiometrics have confirmed the potential of the area and show 
that the Villar Deposit is located on a strong radiometric anomaly that extends 
to the south-west and links up with the Barquilla prospect where Berkeley 
drilled 7 diamond holes in 2008.   An Inferred Mineral Resource of 5.0 Mt at 446 
ppm for 4.9 Mlbs U3O8 has been estimated. 
Lithologies are similar to the Águila Area with host rocks consisting of fine 
grained metasediments that have undergone contact metamorphism associated with 
the Villar del Ciervo-Bañobarez batholith which limits the mineralisation to the 
north.  Mineralisation is associated with a north east-south west oriented 
fracture systems and occurs over an area of 1.5km by 1.3km. 
The Villar historical drill hole database contains 163 (10,000m) diamond drill 
holes with associated chemical assays and 336 roto percussion drill holes 
(23,000m) with down hole e-grades. A proportion of the drill holes do not have 
any assay data or have unsampled intervals so these were all assigned a zero 
grade. The drill spacing is typically 40m x 40m roto-percussion holes which have 
been infilled with diamond drilling to 20m x 20m in the main mineralised areas. 
The mineralisation has been interpreted within an envelope of +100 ppm U3O8 
intersections and a number of flat lying zones were identified extending from 
the surface down to 40 metres.  A block model with a cell size of 10m x 10m x 2m 
(vertical) was constructed with original chemical and e-grade assay data 
composited to 1m after applying a top cut of 5,000 ppm U3O8 to reduce the effect 
of extreme outlier values. Blocks were estimated using Ordinary Kriging with a 
minimum of 5 samples required to interpolate a grade into a block.  An average 
bulk density of 2.7 was applied, based on the Berkeley density measurements 
taken in other areas. 
The Mineral Resource Estimate was classified as Inferred as Berkeley has not 
done any confirmatory drilling on this deposit although a number of Berkeley 
diamond holes drilled at the Barquila Prospect confirmed the nearby historical 
data. 
3.  SUPPLEMENTARY RESOURCE INFORMATION 
 
The uranium grades reported in this release that are annotated with a sub-prefix 
"e" are reported as uranium equivalent grades derived from down-hole gamma ray 
logging results and so they should be regarded as approximations only. 
The Berkeley drill holes were logged with a GeoVista total count gamma tool. The 
gamma tool was calibrated in Adelaide at the Department of Water, Land and 
Biodiversity Conservation in calibration pits constructed under the supervision 
of CSIRO. The various calibration factors were calculated by David Wilson BSc 
MSc MAusIMM from 3D Exploration Ltd based in Perth, Western Australia. 
These Mineral Resources Estimates are presented in accordance with the 2004 
Edition of the "Australasian Code for Reporting of Exploration Results, Mineral 
Resource and Ore Reserves" (JORC Code). 
The information relating to the Mineral Resource Estimates have been compiled by 
Berkeley Resources team of geologists and consulting geoscientists. 
All Mineral Resource Estimate totals have been reported at a 200 ppm U3O8 
cut-off unless otherwise stated. 
Mr Chris Arnold (MAUSIMM) conducted the estimates for the Alameda South deposit. 
 Mr Arnold is the Principal Resource Consultant with AMC Consultants (UK), a 
member of the AusIMM, and a geologist whose career includes more than 20 years 
relevant experience in resource estimation. 
Mr Ross Corben (MAUSIMM) conducted the estimates of the Alameda North and Villar 
deposits.  Mr Corben is currently a Senior Project Geologist with Berkeley 
Resources and is a geologist with more than 15 years relevant experience in 
resource estimation.
