                  Final Confirmatory Drilling Results at the 
                            Salamanca Uranium Project 
 
Berkeley is pleased to announce the completion of the first phase confirmatory 
drilling program at the Águila and Alameda areas and to release the final 
results from the program at the Alameda South deposit. 
A total of 19 diamond holes (1,667m) were drilled at the Alameda South deposit, 
all of which intercepted their intended targets.  The thickness and grade of the 
intercepts continues to provide a high level of confidence in the historical 
drilling information upon which Berkeley has based it's exploration targets 
(Alameda exploration target is 25.5 - 29 million tonnes @ 450 - 500 ppm U3O8). 
It is anticipated that a Mineral Resource Estimate will be completed for the 
Alameda area by the end of the 1st Quarter. 
The notable results presented in Table 1 are based on down-hole gamma logging 
undertaken by Berkeley and are shown as equivalent U3O8 ppm grades or eU3O8.

NOTE - The Alameda deposits have been extensively explored by ENUSA but are not 
classed as Mineral Resources.  The quantity and grade of Berkeley's exploration 
targets for the Alameda deposits are conceptual in nature and based on a review 
of the available data on the projects to date.  As there has been insufficient 
exploration to estimate a Mineral Resource in accordance with the JORC Code, it 
is uncertain whether further exploration will result in the determination of a 
Mineral Resource. 
 
Alameda South Deposit 
The Alameda South deposit is located 12km west of the ENUSA Quercus Plant and is 
accessible via sealed highway and a sealed secondary road. 
Uranium mineralisation at Alameda South is hosted by a deformed sequence of 
regionally and thermally metamorphosed fine grained sandstones and siltstones. 
In addition, granitic sills and shallow dipping dykes were intruded after the 
main folding and metamorphism events followed by the uranium mineralisation. The 
entire sequence has been affected by a later brittle deformation event. 
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. 
All of the intersections correlated well in both grade and thickness with nearby 
vertical historical diamond drill holes. 
 
Data Verification 
120 half metre full core samples from holes ASD-001 and ASD-002 were sent to 
ALS-Chemex in Vancouver for chemical analysis (XRF) to compare with the e-grade 
calculations. The gamma and the assay results compare well.  There is not an 
exact match due to the fact that the radiometric log measures a volume that can 
be up to 50 times larger than a typical drill core and thus gives a more 
representative sample.

1.   Previously announced on 22nd January, 2010 
2.   Holes with no dip and azimuth specified are vertical 
3.   Drill intersections are calculated using a 200ppm lower cut-off with a 
minimum 1m intersection 
4.   Depth figures are rounded, so differences may occur 
Notes 
 
The uranium grades reported in this release are annotated with a sub-prefix "e" 
because they have been 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. 
Drill hole co-ordinates are in UTM 29 ED 50 Datum grid and have been surveyed 
using a DGPS. 
Drill intersections are calculated using a 200 ppm eU3O8 lower cut-off with a 
minimum 1 metre intersection. 
As a check on the down-hole gamma logging data, hand held scintillometer 
readings were taken along the mineralised sections of the core.  These showed 
good correlation with the down-hole gamma readings and were used to identify 
sections which may have been affected by radon.  The down-hole gamma results 
also confirmed visual observations of significant uranium mineralisation in all 
of the holes.
