Quarterly Activities Report
For the Quarter Ended
31st December 2008
Key Developments
Corporate
The Company agreed the terms under which it may acquire up to 90% of the uranium mining assets of the Spanish State uranium company, ENUSA, including an existing uranium processing plant and substantial historical foreign resources. After approval by Berkeley shareholders and the Spanish Council of Ministers, Berkeley will conduct a Feasibility Study on the possibility of recommencing mining uranium based on Berkeley and ENUSA's assets in Salamanca Province.Exploration

Corporate
In December 2008, Berkeley agreed the terms of a Co-operation Agreement with ENUSA Industrias Avanzadas S.A. (ENUSA), pursuant to which Berkeley will undertake a Feasibility Study with a view to re-commencing uranium mining based on ENUSA and Berkeley's assets in Salamanca Province, Spain.
The transaction was approved by Berkeley shareholders on 19 January, 2009.
Pursuant to the Agreement, Berkeley will have the right to acquire up to 90% of ENUSA's uranium mining and exploration assets, which include State Reserve permits containing substantial historical resources and also access to ENUSA's Quercus uranium processing plant (in its present condition), which was previously permitted to produce up to 950tpa of U3O8.
Berkeley's objective is to generate a total resource base for the project of over 65m lbs of U3O8 and to complete a Feasibility Study within 18 months of approval by the Spanish Government.
The ENUSA assets include:
The main terms of the Co-operation Agreement are:
Further details of the transaction and the assets are set out in the announcement dated 9 December 2008.
Costs Review
The unprecedented downturn in global economies and markets in late 2008 is likely to adversely affect the availability and cost of capital for junior resource companies for the foreseeable future. The Directors of the Company therefore took the view that it was prudent to undertake an immediate review of operational activities, staffing levels and costs, to ensure cash resources are maintained for the impending ENUSA Feasibility Study.
As a result a number of actions were taken in late 2008, including severe curtailment of exploration programs. Unfortunately, these actions resulted in a number of retrenchments and the Company is now maintaining staffing at a level appropriate to undertake the Feasibility Study, and enable limited exploration of the ENUSA ground.
Additional cost saving measures are also under consideration.
EXPLORATION
Caceres VI Project - Gambuta
Following completion of the initial 36 hole RC and diamond drilling program in July 2008, and calculation of the maiden Gambuta inferred resource of 9.23 million pounds of U308, drilling activities were halted during the high risk part of the local fire season.
Interpretation of the initial results indicated that the deposit was still open to the NW, where the final drill traverse intersected significant thicknesses of mineralization. RC drilling recommenced in October to complete the most north-westerly drill traverse and to test for extensions to the NW. Whilst continuity of mineralization was established across the last drill traverse, the first extension traverse, 200m to the NW, revealed >90m of Tertiary sediments. This abrupt thickening of the Tertiary cover, from 10m in the previous traverse, indicates normal faulting with the NW block down.
The Gambuta deposit has potential as a stand alone heap leach operation, with uranium recovery from an operation at the Quercus plant. Therefore further drilling and metallurgical testwork will follow progress of the ENUSA project.
Regional Exploration
The strong reduction in drilling activity during the quarter provided an opportunity to undertake an in-depth technical review of the Company's exploration projects. This included a revision of the current exploration process in parallel with an examination of the target portfolio and tenement holdings.
In addition water sampling was successfully trialled for its potential to identify blind uranium mineralisation, where surface radiometric responses are absent because prospective basement stratigraphy is overlain by Tertiary sediments.
Assessment of Berkeley's exploration portfolio was divided into two categories: firstly to review known targets which resulted from both historical work and Berkeley exploration; and secondly to review the potential of ground holdings based on conceptual targeting. In both cases, these reviews benefited from the Company's increasing confidence in identifying the key ingredients required for forming an Iberian-type uranium deposit. A total of 23 granted licences and applications in the Salamanca, Caceres and Toledo provinces, covering an area of approximately 200,000ha, were covered.
At the Salamanca 1 project, review of the recent drilling programs on known prospects enabled approximate estimation of additional resource potential within the project and prioritisation of greenfield exploration targets when work resumes.
In Caceres Province, the prospect reviews also included field work to assess additional potential along strike from known prospects, with results feeding into decisions re future exploration priorities and opportunities for ground relinquishment.
The conceptually targeted areas were subject to regional reconnaissance scale ground radiometric surveys and geological mapping, with some very encouraging results. Some of these areas have never previously been assessed for uranium. Others have apparently been subject to some ground radiometric surveys by JEN and ENUSA, which allowed Berkeley geologists to focus on field inspection of anomalous areas identified from historical information. Some essential follow up field work is required in the current quarter before results can be reported.
Water Sampling
Berkeley recognises strong potential for uranium mineralisation where prospective Late Proterozoic and Lower Palaeozoic basement is overlain by younger Tertiary rocks. In such areas any anomalous radiometric response from mineralization will be masked by relatively thin cover and therefore blind deposits will be difficult to detect by the usual uranium exploration technologies. Therefore it has conducted geochemical orientation surveys using water from existing bore holes around known mineralisation in the Caceres and Salamanca provinces with encouraging results. This method will be used, in combination with geological mapping, to assess the potential of significant areas of untested Tertiary cover over prospective stratigraphy, particularly within the ENUSA project.
Metallurgical Testwork: Retortillo
A total of 800kg of representative sample material from the Retortillo deposit were sent to SGS Mineral Services in Perth, Australia in December, 2008, with the aim of assessing the potential for establishing a heap leach operation.
The initial program of testwork on these samples has the following objectives:
Samples were also sent to Ultrasort Pty Ltd in Sydney for initial testwork on their amenability for radiometric sorting.
Initial results are expected in the March 2009 quarter.
