Quarterly Activities Report - June 2010
Significant activity toward the initial Feasibility Study for the Salamanca
Uranium Project (SUP) took place over the last quarter. Encouraging progress in
all project areas has been achieved. Work focused mainly on tank leach
metallurgical test work and Reverse Circulation (RC) drilling aimed at upgrading
and extending the Mineral Resources announced in the first quarter.
The highlights for the quarter:
1. Uranium recoveries up to 94% from metallurgical tank leach tests for
composite samples from Sageras, Palacios and Alameda South with a relatively
coarse grind and low acid consumption
2. Recoveries of up to 87% U3O8 in Bottle Roll Leach Test work (BRT) simulating
heap leach characteristics in advance of the column leach test work
3. The Exploitation Plan for the SUP which includes the mining plan,
reclamation plan, environmental and radiological study was completed and has
been submitted to Berkeley's JV partner ENUSA
4. Commencement of the RC drilling program at Sageras, Palacios and Alameda
South to upgrade resource categories and test for possible extensions. The
8,000m programme was 45% complete by the end of the quarter. Results to date
confirm the resource models and have identified additional potential at Sageras
where two holes have discovered a new mineralised zone, and at Alameda where
initial chemical assay results are better than expected
5. Updated resources for Sageras and Alameda South and new pit optimisations
and production schedules will be finalised in the 3rd quarter
6. The environmental and radiological baseline studies are approximately 60%
complete and scheduled to be completed in the 4th quarter
7. Approximately five tonnes of "representative" core samples were selected for
dispatch to SGS in Perth for column leach test work
8. A combined RC drilling and diamond drilling programme was planned and
submitted to the Mines Department for the Retortillo and Santidad deposits
Berkeley Managing Director, Mr. Ian Stalker commented "The quarter has been an
extremely productive period as we progressed the Salamanca Uranium Project. The
very encouraging tank leach results indicating high recoveries at a coarse grind
and low acid consumption add to our knowledge and assist in project design
criteria and equipment selection. The infill resource and extension RC drilling
programme is nearly 50% complete. The initial results are providing upside to
the existing resource models and equally importantly enable upgrading of the
Inferred resources at Alameda and Sageras."

Salamanca Uranium Project Feasibility Study
Work towards the initial Feasibility Study is progressing well and is scheduled
to be completed by the end of the year. The Feasibility Study is focussing on a
tank leach scenario using the Quercus Plant to produce 2.1mlbs U3O8 per year
from the Sageras, Palacios and Alameda South deposit. The aim is to complete the
study by the end of the year. Simultaneously, work is progressing to assess the
heap leach options for these deposits and the satellite deposits at Retortillo.
1. Drilling Programmes
Diamond and RC drilling operated continuously during the quarter for a total of
5,199 metres (Table 1) at Alameda South, Sageras and Palacios. At the end of
the quarter, four RC rigs and one diamond rig were operating.

This work addressed several objectives, as detailed below.
Heap Leach Metallurgical diamond drilling - approximately 1,100 metres of large
diameter PQ diamond drilling at Sageras and Alameda was completed in May to
generate additional material for metallurgical test work. These holes were not
included in the Mineral Resource Estimates announced in the first quarter but
the e-grades correlate well with the resource models and provide further
confirmation of the historical drilling data.
RC Drilling- approximately 8,000 metres of planned RC drilling commenced in June
with the following objectives:
·To upgrade the current resource classifications from Indicated to Measured and
from Inferred to Indicated
·To test for lateral and depth extensions of current resources
·To test a number of high priority targets identified by surface mapping and
ground radiometrics, proximal to the existing resources
·To complete sterilisation drilling of the area to the north of Sageras where
the conceptual waste dump and crushing facility have been located
This programme was approximately 45% complete by the end of the quarter and is
scheduled to finish in early August. All of the RC samples are being sent to
ALS Chemex in Vancouver for chemical analysis after preparation at the ALS
Chemex laboratory in Seville. Down hole gamma readings are used to select the
anomalous intervals to assay and the calculated e-grades on the completed holes
are showing very good correlation with the resource model.
The initial chemical assay results indicate potential upside to the resource
model at Alameda South with some high grade intersections returned in holes
ASR-029 (28 - 63m, 35m @ 2,044ppm U3O8), ASR-031 (29 - 55m, 26m @ 3,923ppm U3O8)
and ASR-032 (22 - 40m, 18m @ 1,401ppm U3O8).
At Sageras, two RC holes have identified a new mineralised zone that appears to
be open to the north-west. Hole ZRC-012 intersected very high grade
mineralisation from 44m depth over a 3 metre interval grading 7,027ppm U3O8.
This intersection will be followed up by further RC drilling in the next
quarter.
A list of notable intersections for the quarter is shown in Table 2. The
diamond drill holes are presented as eU3O8 grades calculated from down hole
radiometrics whereas the RC holes are presented as U3O8 chemical assays.

A full table of intersections for the quarter is included in the Appendix. They
have been calculated using a nominal 200ppm lower cut-off and a minimum
thickness of at least 1m. All intersections correlate well with the historical
drill hole data in both thickness, location down the hole and grade.
2. Metallurgical Test Work
During the quarter further representative samples taken from diamond drill core
from the Palacios, Sageras and Alameda South deposits were sent to the SGS
Metallurgical laboratories in Perth, Australia to continue the ongoing testwork
supervised by Orway Mineral Consultants Pty Ltd of Australia.
The first phase of the testwork campaign commenced in March 2010 and has been
focused on optimising the process conditions for treating the uranium ore
lithologies at Sageras, Palacios and Alameda in a tank leach configuration.
Phase 1 is scheduled to be completed in the 3rd quarter 2010 with the following
testwork in progress:
1 Preliminary mineralogy on various ore types
2 Comminution (crushing and grinding)
3 Tank leaching
4 Heap leaching
5 Engineering Data
6 Geotechnical and geochemical testing of the final process residues and
7 Effluent neutralisation
The initial results can be found in the Berkeley announcement - "Metallurgical
testwork update" released on the 7 June 2010.
Mineralogy
QEMSCAN mineralogy on composites of the ores from Sageras, Palacios and Alameda
has revealed:
1 The Sageras uranium minerals have a finer grain structure (< 20 microns) and
are predominantly coffinite with a lesser quantity of uraninite
2 In Palacios, the uranium minerals have a coarse grain structure (20 - 50
micron) with uraninite dominating and lesser quantities of coffinite, often
intergrown
3 The Alameda uranium minerals are medium grained in between Sageras and
Palacios in grain size and have an almost equal distribution between uraninite
and coffinite
On the basis of these results, Palacios has the best leaching characteristics
probably because the uraninite is more amenable to leaching than coffinite and
coarser grains have more exposed surfaces available to leaching.
Comminution
A second batch of metallurgical test work samples consisting of 1,274kg of
diamond drill core was sent to SGS in June for detailed comminution test work.
This followed a review of the historical comminution flow sheet which showed
that a significant uranium concentration can be achieved in a crushing and wet
scrubbing process. This test work commenced during the quarter and is aimed at
determining additional comminution data associated with crushing, scrubbing and
ball milling. In conjunction with this test work, other physical concentration
and gravimetric processes will be examined. These include:
1 flotation (oxide and sulphide)
2 spirals
3 various gravity processes
Agitated Tank Leaching
Leach tests are on going on bulk composite samples:
4 Alameda and Palacios continue to yield high leach extractions of uranium of
93 - 94% in batch leaches with modest sulphuric acid consumptions of 18 - 23
kg/tonne of ore
5 The leach extractions for the Sageras composite are typically 87 - 88% at
acid consumptions below 10 kg/t
6 All the above results have been achieved at a grind size of P100 1.5 mm, at
a temperature of 20ºC with very low oxidant requirements of 1 - 2 kg/tonne of
commercial pyrolusite
7 The leach-end slurries were amenable to vacuum belt filtration with
acceptable treatment rates. This development will permit the disposal of "dry
tailings" resulting in reduced environmental issues
Bottle Roll Leach Tests (BRT)
During the quarter a parallel static heap leach test work programme commenced to
explore the amenability of ore to heap leach. This work started with a suite of
intermittent bottle roll tests as a precursor to future column tests, scheduled
to start in the 3rd quarter.
The initial bottle roll test have provided an encouraging response for all ores
with Sageras at 82%, Palacios at 85% and Alameda at 87% average extractions of
uranium.
The consulting group Kappes Cassidy are supervising the heap leach test work
after selecting over 5,000kg of diamond drill core from the Alameda South
deposit. This material will be dispatched to SGS Perth in July. The first one
metre column tests are due to start in August with initial results expected in
October.
3. Environmental Studies
One of the most important components of the Feasibility Study is to establish
the Environmental Baseline Study conditions at all of the project sites. This
work is being co-ordinated by Golder Associates with most of the studies
commencing during the 1st quarter. In general, the work is progressing very
well with regular monitoring continuing during the quarter and it is on track to
be completed by the end of the year.
10 Land-use and landscape. Berkeley retained AIA Consultants to perform the
landscape characterisation study. The study commenced in March and the final
report is due by the end of July. A soil sampling program was initiated and
samples were collected in May. The samples are being analysed at the laboratory
of the University of Cantabria for a comprehensive suite of parameters
11 Climate and Meteorology. A weather station has been installed by INGEMISA in
Alameda and it is now working as intended with data being collected and managed
by INGEMISA. Historical data will be purchased for nearby weather stations from
AEMET (Agencia Estatal de Meterologia). Several locations have also been
selected at Aldea del Obispo, Castillejo de Martín Viejo, Ciudad Rodrigo,
Fuentes de Oñoro, Gallegos de Argañán, Saelices el Chico and Villar de Argañán.
Work is progressing as planned
12 Air Quality. The air quality monitoring program has been developed based on 9
preliminary monitoring points for sedimentable particles (6 in Sageras and
Palacios and 3 in Alameda). Scheduled monitoring of dust particles will
commence once the agreements with the landowners have been cleared. Samples will
be analysed at INTERLAB for physical/chemical parameters and at EICHROM for
radiological parameters
13 Noise. The noise monitoring program has been planned based on a total of 18
monitoring points for baseline noise levels, 12 in Sageras and Palacios and 6 in
Alameda. The first monitoring campaign was completed by Berkeley and Golder in
April and the next monitoring campaign will be performed in October.
14 Surface Water Quality. The surface monitoring program has been developed
based on a total of 7 surface water monitoring points in the area of Sageras and
Palacios and 3 surface monitoring points in Alameda. Monitoring is being
undertaken by Berkeley under the supervision of Golder Associates and sample
analysis is done by AGQ laboratories in Sevilla. The first monitoring campaign
was performed in February with ongoing bi-monthly sampling programmes. The
results from the first campaign indicate no relevant affection of surface water.
In addition, samples of the ENUSA discharge has been taken and sent for analysis
15 Groundwater Quality. The groundwater monitoring programme includes publicly
available information from wells and springs in nearby villages. In addition,
Golder has established 6 groundwater monitoring points in the area of Sageras
and Palacios and 3 groundwater monitoring points in Alameda. Monitoring is being
undertaken on a quarterly basis during 2010 with the first campaign completed at
the end of March. Sampling and analysis of groundwater is continuing as planned
16 Flora and Fauna.
o The study concerning aquatic flora, fauna and sediments studies has been
appointed to IPROMA SL. The scope of works includes surveying and sampling in
Alameda, Sageras and Palacios
o The study concerning vegetation and flora studies for the areas of Alameda and
Sageras/Palacios has been appointed to the Catedratico Botanical University of
Salamanca. A literature study over the areas was performed in March/April and
the field campaign started in April (weekly site visits have been planned until
July). The final reports are expected in July
o The study concerning fauna (mammals, fish, and reptiles) has been assigned to
the University of Salamanca. The study started in May and the final report is
expected in August
o The study concerning local birds has been assigned to Estudios Zoologicos
Iberia SL. The final report will be delivered by end July. The study includes a
special focus on the Black Stork
17 Socio-Economic Baseline. The Socio-Economical Baseline study has been
assigned to the Geography Department at the University of Salamanca. The scope
of the study includes a compilation of baseline socio-economical data, spatial
planning aspects and traffic. The study also includes Phase I of a social
acceptance study (identification of relevant target groups and the design of a
suitable format of a survey). During May, Golder Associates has discussed the
ESIA process and the public consultation processes in relation to the Berkeley
Public Relations Strategy in order to co-ordinate the two efforts. A selection
process for a potential PR consultant has been initiated.
4. Radiological Studies
The radiation assessment for the Feasibility Study is being conducted by an
Australian consulting company, Paulka Radiation & Environment. All methodology
employed in the assessment has been based on international standards recommended
by the International Atomic Energy Agency (IAEA) and the International
Commission of Radiological Protection (ICRP). These bodies are recognised by
the European Union as the standard for radiation protection. In addition,
recommendations from international best practice guidance material have been
incorporated where applicable.
The first part of the assessment has been the design and implementation of a
baseline monitoring program to characterise the current radiological aspects of
the project. The monitoring programme includes parameters for radionuclides in
dust, radon, gamma dose, radionuclides in soils, ground and surface waters and
biota. The baseline monitoring programme commenced in February 2010 and is
approximately 50% complete. During the quarter the following monitoring was
conducted:
1 The second round of surface water sampling was completed and results
received for the first and second rounds
2 Water samples were collected from public fountains and results received.
3 Groundwater samples were collected as part of the hydrogeological pumping
tests and partial results were received
4 Soil samples from the various landform types were collected in
collaboration with the soil and landscape consultants, analytical results are
pending
5 Quarterly continuous dust deposition, radon and gamma radiation monitoring
commenced
6 Aquatic plants, fish and river sediments were collected by the Flora &
Fauna consultants, analytical results are pending
Analysis of these results will occur in the 3rd quarter. The remainder of the
assessment will involve the identification and quantification of any radiation
risks the project may have with regard to workers, the public and the
environment. The assessment will recommend design and institutional control
mechanisms that will assist in keeping radiation doses optimised to As Low as
Reasonably Achievable (ALARA). The results of the radiation assessment will
feed into the Feasibility Study, the Environmental Impact Assessment and
applications for authorisations to operate.
During the quarter the following radiation assessment tasks were undertaken:
1 Collation and analysis of historic radiological data provided by ENUSA.
This is now ready for reporting; and
2 Development of draft radiation design criteria for the mining and
processing engineering teams for inclusion in the Feasibility Study
The majority of the radiation risk assessment has been scheduled for completion
during July and August with the final report to be issued in the 4th quarter.
5. Water Management
The water management programme is progressing well with a significant amount of
fieldwork undertaken during the quarter. The long term groundwater monitoring
at Alameda and Sageras is continuing and the short term low rate hydraulic
testing is ongoing at Sageras, Palacios and Alameda as well as groundwater
tracer tests. Conceptual hydrogeological models have been developed for each
deposit:
1 Palacios - Permeability (K) of 10-7 m/s will result in 400kl/day groundwater
inflows to the pit which are very low and should be easily manageable by pumping
with most water being evaporated.
2 Sageras - K between 10-7 and10-6 m/s will result groundwater inflows between
400 to 2,000kl/day. Flows may be higher in Tertiary covered areas (10-5) where
extra flows of up to 300kl per day may be intercepted. However, surface water
can easily be diverted around the open pit.
3 Alameda - K from 10-6 and10-8 m/s resulting in flows from 600 to 2,500
kl/day.
These results show that ground water inflows to the open pits should not be
excessive and will be easily managed during mining activities.
This on-going work and the results derived are currently being used to complete
the water balance and dewatering planning aspects of the water management study.
6. Waste Characterisation
The waste characterisation programme is a critical part of the Feasibility Study
process as all potential waste material types must be identified, classified and
characterised as part of the exploitation application process. This programme
is being supervised by Golder Associates and is on schedule although it is
dependent on the availability of the residue samples from the metallurgical test
work being undertaken at SGS in Perth. These samples are expected to become
available in July after which characterisation of the samples can be initiated.
During the quarter, a review was conducted of the anticipated waste rock
characteristics based on information on the site geology and mine planning.
Forty five waste rock samples (Sageras, Palacios and Alameda, five weathering
stages and eight lithologies) were selected by Berkeley geologists and reviewed
by Golder Associates, before being shipped to SGSCEMI in Vancouver for
geochemical characterisation tests including:
1 mineralogical analysis by XRD
2 chemical assay
3 acid base accounting (ABA)
4 net acid generation (NAG) testing
5 radiological analysis
After completion of the initial testing and review of the analytical results,
subsets of these samples were submitted for static leach testing (SPLP) and
analysis of NAG leachates. After a review of the leach test results, a smaller
subset will be submitted for kinetic testing (HC-tests).
In addition, eight residue samples (seven leach products and one water treatment
plant residue) and seven feed samples were selected from the tank leach test
work program at SGS in Perth for geochemical characterisation. More residue
samples will become available by the end of July and these will undergo the
geochemical characterisation tests listed above. After completion of the July
testing and review of the analytical results, a subset of these samples will be
submitted for analysis of NAG leachates and kinetic testing.
7. Mining Studies
A considerable amount of work was undertaken during the quarter following the
announcement of the Mineral Estimates at the end of March. Pit optimisations
were completed for various processing and production options and operating costs
were further refined following discussions with a number of mining contractors.
A summary of the mining studies undertaken during the quarter include:
1 The first draft of the Feasibility Study geotechnical report was received
from AMC Consultants (UK) which included the configuration of bench batter
angles and berm widths. The new overall pit slope angles range from 45º to 50º
resulting in potentially lower strip ratios.
2 AMC Consultants (UK) has completed updated pit optimisations for Palacios,
Sageras and Alameda South. The optimisations used more accurate operating costs
after further contact with potential mining contractors, new geotechnical
parameters and a U3O8 price of US$60 per lb.
3 Detailed pit designs for all three deposits commenced using the new pit
slope and optimised pit shells and will be completed in July.
4 A detailed mining schedule has been developed based on the latest processing
plant requirements and using the updated pit optimisation results.
5 A review of the potential waste dump locations was undertaken during the
quarter and conceptual designs for the dumps and tailings management facility
were completed by Golder Associates.
6 Trade off studies are underway to look at the cost benefits of an "owner
operated fleet" as opposed to using a mining contractor.
7 The January 2008 Scoping Study pit optimsations for Retorillo and Santidad
were incorporated into the overall mining schedule.
8. Process Engineering
During the quarter, work began on interpreting the test work results and
constructing the basic engineering package for more detailed design by Aker
Solutions. The package components include:
1 Basis of Design - testwork interpretation into design data
2 Process Flow diagrams - reflecting the flowsheet details
3 Mass Energy Balance - for the concentrate and metallurgical plants
4 Mechanical Equipment List
5 Motor / Starter List
6 Plant Layout - plot plans
7 Operating Cost Model
The final engineering data will be delivered to Aker Solutions in the 3rd
quarter for review and incorporation into the Feasibility Study. Aker Solutions
has also commenced several trade off studies related to the process plant.
9. Permits and Licensing
An application was submitted to the Salamanca Mines Department for infill and
extension RC drilling at the Retortillo and Santidad deposits. The main
objective of the drilling campaign is to upgrade the Inferred resources into
Indicated and Measured categories. In addition, 15 diamond drill holes were
planned to provide sufficient material for metallurgical heap leach test work.
Table 3 gives a breakdown of the number of holes and metres to be drilled at
each deposit.

11. Supplementary Information
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 intersections are calculated using a 200 ppm eU3O8 lower cut-off with a
minimum one metre intersection
The Mineral Resources 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 in this report that relates to the metallurgical test work
results is based on information compiled by Mr Grenvil Dunn, who is a Chemical
Engineer and a Member of the South African Institute of Mining and Metallurgy.
