BERKELEY RESOURCES LIMITED

Quarterly Activities Report - March 2010

Berkeley Resources Limited ('Berkeley' or 'Company') (ASX: BKY, AIM: BKY) is pleased to present its quarterly report for the period ended 31 March 2010. During the quarter the Company completed confirmatory drilling at the Salamanca Uranium Project and the initial estimation of Mineral Resources for the Sageras, Palacios North and Alameda South uranium deposits. As a result there has been a substantial increase in the Company's Mineral Resources. The quarter's highlights include:

 

1. The total Mineral Resources within Berkeley's projects have now increased to over 80 Mlbs of U3O8 at a 200 ppm cut-off:

 

Table 1 - Berkeley Projects Total Mineral Resources

Area	Tonnes	U3O8	U3O8
	(Mt)	(ppm)	(Mlbs)
Retortillo	19.9	512	22.5
Águila	22.5	417	20.7
Villar	5.0	446	4.9
Alameda	22.5	466	23.1
Gambuta	11.3	371	9.2
Total	81.2	450	80.4

 

2. The confirmatory drilling program at the Palacios North, Sageras and Alameda South deposits confirmed the extensive historical drill data and indicated potential for additional resources at all 3 deposits. A Reverse Circulation (RC) drilling program is planned in the June quarter to test these areas and also upgrade final resource estimates for the Definitive Feasibility Study (DFS).

3. The DFS commenced in January, is progressing well on a broad front and is on track to be completed by the December quarter.

4. Two tonnes of drill core samples for metallurgical testing were sent to Perth in January and dynamic leach metallurgical test work has commenced. Initial comminution, radiometric ore sorting and leach test results are encouraging.

5. The team in Spain was strengthened with two key senior staff appointments. Mr Henry Horne has been appointed Chief Financial Officer, and Javier Colilla, former Senior Vice President Corporate of Río Narcea Gold Mines Ltd, has been engaged to assist in the legal aspects of the permitting and licensing process.

During the quarter, Berkeley completed the conversion of it's exploration targets into Mineral Resources and subsequently made two significant resource announcements increasing the total Mineral Resources within Berkeley's projects from 26.1 Mlbs to 80.4 Mlbs of U3O8 at a 200 ppm cut-off. These announcements followed the completion of the 5,000m confirmatory drill program started in October 2009.

Berkeley's DFS is focused 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 key resource developments for the quarter are:

·; 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 Águila Area, which includes the Sageras, Palacios and Majuelos deposits, all within 3 kms of the Quercus processing plant, total 22.5 million tonnes at an average grade of 417 ppm for 20.7 Mlbs U3O8. These Mineral Resources include 24% Measured Resources and 26% Indicated Resources.

·; Mineral Resources in the Retortillo Area, which include the Zona 7, Retortillo, Santidad, Caridad, Las Carbasand Cristina deposits, total 19.9 million tonnes at an average grade of 512 ppm for 22.5 Mlbs U3O8 These Mineral Resources include 27.1% Indicated Resources.

·; 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, all in the Inferred category.

·; Mineral Resources for the Villar Deposit total 4.9 Mlbs at an average grade of 446 ppm U3O8, all in the Inferred category.

 

A summary of the five Resource Areas with a breakdown of the resource categories is shown in Table 2.

A full table of eU3O8 intersections for the quarter is included in the Appendix. The intersections 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.

The main objectives of the drilling campaign were to confirm the historical drill data, provide geological and assay data to enable the calculation of Mineral Resources and to provide representative material for tank leach metallurgical test work. All of these objectives were achieved and in addition, the results have shown excellent potential at all 3 deposits for defining additional resources.

Drilling is continuing at Alameda South and Sageras to generate sufficient material for the planned heap leach metallurgical test work program.

Berkeley is continuing to re-probe historical drill holes which remain accessible in the Águila Area deposits with over 220 holes completed by the end of the quarter. The results continue to show a good correlation when comparing the historical e-grades with the Berkeley e-grades over the same mineralised intervals. The Berkeley e-grades are 13.4% higher than the historical e-grades in the probed holes to date. At this stage, the reason for this difference is under investigation, but it may indicate that the historical grades used in the resource estimations are conservative.

The Berkeley e-grade calculations have been reviewed by an external consultant and the gamma probe has been calibrated at a recognized facility in Australia. In addition, 384 full core half metre samples taken from 8 drill holes at Sageras, Palacios and Alameda have been assayed by X-Ray Fluorescence Spectroscopy (XRF) in Vancouver at ALS-Chemex and these have been used to confirm the accuracy of the Berkeley e-grades. In general, radiometric logging is the preferred method for estimating the grade and thickness of uranium mineralisation. The gamma tool measures a volume that can be up to 50 times larger than a typical drill core and thus gives a more representative sample.

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. A total of 90 holes for 8,000 metres have been planned with the main focus on improving the confidence levels in the deposits in order to significantly upgrade the resources. A number of holes will also test for down dip and lateral extensions.

During the quarter, a review of the exploration potential by Berkeley has identified some high priority targets in the Capilla and Marialba prospects close to the Águila Area as well as a number of more distant targets in the Espeja and Barquilla prospects. Historical wide spaced drilling (1km centres) at Espeja has intersected some mineralisation beneath the Tertiary cover along the granite contact south of Alameda. A detailed review of this data and field reconnaissance work is currently underway.

 

Definitive Feasibility Study (DFS)

The Salamanca Uranium Project (SUP) Scoping Study was completed in December 2009 and it clearly demonstrated the technical and economic viability of the project. In January 2010, the Company started the DFS and this is scheduled to be completed in the December quarter.

Environmental and Radiological management forms a critical and important component of the DFS, and Berkeley intends to implement world's best practice. Therefore the following consultants in Environmental, Radiological and Social Studies have been appointed to work closely with Berkeley's experienced team in Spain, and to ensure full compliance with governing legislation:

·; Golder Associates (Spain)

·; Paulka Radiation and Environment Pty Ltd (Australia)

·; Salamanca University

Golder Associates have over 50 years' experience working worldwide in the mining industry and have been involved in the development of most of the new mines in Spain. They will complete the environmental and social baseline and impact assessment studies, rehabilitation & reclamation plans, closure plans, waste and tailings management, and provide assistance in statutory permitting and licensing requirements.

Paulka Radiation & Environment Pty Ltd is an Adelaide-based consultancy that provides specialist radiation advice and service to the uranium mining industry. It is led by Director Sharon Paulka who has over 20 years' experience in radiation protection and uranium work in Australia and Canada.

Assisting Golder Associates in the social and community studies will be experienced and qualified Professors from the Salamanca University, who have extensive local knowledge and have been involved in the project over the past four years.

Water management studies are a key component of the study and incorporate interaction with the other project disciplines. They will be managed by Aquaterra and Ingemisa SA. Aquaterra are specialists in ground water, surface water and water engineering and have worked in a number of Australian Uranium projects. Complementing Aquaterra will be Ingemeisa SA, a Spanish engineering firm established in 1978 with wide expertise in water management and environmental studies.

Metallurgical and Processing studies will be supervised by Orway Mineral Consultants (Perth), Kappes Cassiday (Perth) and Aker Solutions (UK), who collectively have extensive experience in the uranium industry, both in tank and heap leaching.

Metallurgical test works will be completed by SGS Lakefield in their Perth, Australia laboratory and these started in February.

AMC Consultants (UK) have been appointed to complete the geological, geotechnical and mining studies, and have experience in Spain having previously completed the Retortillo and Salamanca Uranium Project Scoping Studies for Berkeley.

DFS Update

Environmental Studies

 

Detailed environmental studies commenced during the quarter in order to establish the baseline conditions at all the project sites. A large number of activities were initiated including:

·; Surface water quality - sampling points were established at Áquila and Alameda in February.

·; Groundwater quality - sampling started at Áquila and Alameda in March and will continue quarterly for physical, chemical, radiological and microbiological parameters.

·; Air Quality - environmental assessment of the pre operational conditions of the air quality in the project areas and potential effects on the surrounding areas. The equipment is due to arrive in Spain in April and monitoring to start immediately.

·; Noise - environmental assessment of the pre operational noise levels in the project areas and surrounding areas of influence.

·; Land and Soil use - this work will be undertaken by Golder Associates and is scheduled to start in April. It includes the following activities:

 

Ø Edaphologic description and characterization.

Ø Processes (scour and other) and risks (degradation and pollution).

Ø Description and characterization of the current use and exploitation.

Ø Historical research.

Ø Agrologic capacity and exploitation capacity.

Ø Cartography: general and detailed.

Ø Geochemical studies are included.

Ø Radiological parameters

 

·; Vegetation studies - to be completed by Salamanca University and Golder Associates covering the current vegetation and preservation of the areas of influence. Initial studies commenced in March.

·; Land Fauna - studies started using the Salamanca University - Department of Zoology to determine land mammals, reptiles, and amphibians present at the research areas of Alameda, Sageras and Palacios and identify historic records in the area, legal situation of species and any possible conservation plan. This work is planned to start in April and should take 4 months to complete.

·; Avifauna - studies started in March and are being conducted by Estudios Zoologicos Iberia. The work includes the identification and bird research in the project and surrounding areas. Particular attention will be applied to the rare birds (Black stork, golden eagle, Montagu's harrier, booted eagle, short-toed eagle, black-bellied sand grouse and little bustard)

·; Aquatic Flora, Fauna and Sediments -being supervised by IPROMA Consultants working with Golders, Paulka Radiation and Berkeley, covering the possible accumulation of heavy metals and radiological levels and biological matrices in the soils and sediments. Work is scheduled to start in April.

·; Socioeconomics - studies to be conducted by the Salamanca University and based on:

 

Ø Detailed study of the socioeconomic environment.

Ø Influence of the mining project in the spatial planning.

Ø Social acceptance survey aimed at identifying groups of interests and setting a social participation program considered fundamental to announce the project publicly.

 

Radiological Studies

The radiological assessment baseline monitoring program commenced in March 2010 with the following objectives:

·; To characterise the current project site conditions and assess the potential radiation impacts from the project on workers at the mine site and members of the public living in the surrounding communities.

·; To advise on control mechanisms to ensure all radiation exposures from the project are optimised to "As Low As Reasonably Achievable", taking into account economic and social factors (ALARA).

 

The assessment is being supervised by Paulka Radiation Consultants and is on schedule with no delays identified.

 

Metallurgical Test Work

2,000kg of diamond drill core was sent to the SGS Metallurgical Laboratories in Perth, Australia for a comprehensive metallurgical test work campaign supervised by Aker Solutions and Orway Mineral Consultants. The material was selected on the basis of lithology, oxidation and grade from the Sageras, Palacios North and Alameda South deposits.

The extensive test work campaign commenced during March 2010 and should be completed by the end of July 2010 with the following test work in progress:

·; Comminution

·; Flotation

·; Radiometric Ore Sorting

·; Leaching - both bottle roll and tank leach

·; Filtration

·; Solvent Extraction

·; Uranium Product Recovery

·; Environmental

·; Reagent Identification

 

Initial work completed and results are summarised below:

 

·; Radiometric Ore Sorting - Early data is indicating that ore sorting could be a viable technology for the Salamanca ores. Initial scouting tests results have yielded encouraging results on a large laboratory scale ore sorter. Sorting processes of this nature can upgrade the uranium composition of the ore fed to the processing plant. Further tests are being considered on a large feed tonnage.

·; Tank Leach - Early leach results from a composite of the Palacios North, Sageras and Alameda South ore have returned leach extractions between 92% and 93%. All tests to date have used a coarse grind to the leach feed of P80 (810 microns). The benefit of a coarse grind is in the lower energy requirements in the comminution circuit. These results have not been optimized and it is expected that they will improve when the structured leach program is concluded. Variability leach tests will also be conducted in the various lithologies present in the three deposits.

·; Bottle Roll Tests - A suite of bottle roll tests are in progress as a precursor to future column tests and the results will be reported in the next quarter.

·; Mineralogy - Representative samples of the three ore types have been selected for host rock and value metal mineralogy.

·; Mass Balance Modeling - Elemental Engineering of Sydney, Australia have been engaged to develop the mass balance model for the project. The model is being founded on early mineralogy and leach test work outcomes and will be further calibrated as more test data becomes available. The data from this model will be essential for integrating the Salamanca process with existing equipment in the Quercus Plant.

·; Engineering - AkerSolutions have generated a preliminary plant design which will be progressed as the test work results become available.

·; Water Treatment - A conceptual process block diagram has been proposed for the combined central Effluent Treatment Plant (ETP) treating all existing plus future liquid effluent streams.

·; Flowsheet - A simplified version of the proposed flow sheet has been designed.

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 1 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. Mr Dunn is a Technical Consultant with Orway Mineral Consultants who are consultants of Berkeley Resources. Mr Dunn has sufficient experience which is relevant to the style of mineralisation and type of deposit under consideration and to the activity which he is undertaking to qualify as a Competent Person as defined in the 2004 Edition of the Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves (The JORC Code).
