Drilling Report

Berkeley Resources Limited 22 June 2007 22 June 2007 BERKELEY RESOURCES LIMITED INITIAL DRILLING RESULTS CONFIRM SAGUAZAL POTENTIAL The Directors of Berkeley Resources Limited (AIM: BKY.L) are pleased to announce the initial results of the current drilling programme at the Saguazal project in Caceres Province, Spain. This project is the second mineralised area to be tested with confirmatory drilling by Berkeley in its Spanish uranium exploration programme. Five of the six diamond core holes drilled to date intersected significant shallow mineralisation with the best results including: Hole SAG-005 22.0 metres @ 0.3072% U3O8 from 5.0m (radiometric equivalent) Hole SAG-002 3.5 metres @ 0.4461% U3O8 from 15.0m (chemical assays) Hole SAG-004 6.45 metres @ 0.2416% U3O8 from 13.3m (radiometric equivalent) The initial Saguazal drilling programme consists of eight vertical and angled diamond core holes designed to confirm the results of the historical drilling and to clarify the geology and structure of the mineralisation. Six holes have been completed, with chemical assays received for the initial two holes. These initial assays have been correlated with the downhole radiometric logs to provide predictions of the radiometric equivalent assays for the next four holes, for which chemical assays are awaited. These predictions have been made by Berkeley Resources' Senior Exploration Consultant, Roger Murphy - former Chief Geologist at the Rossing Uranium Mine. TABLE 1.

Appendix These results provide encouraging validation of previous drilling (mainly reverse circulation, with minor diamond core drilling) and confirm the presence of high grade areas within the Saguazal mineralisation. Drilling to date consistently reveals a variably fractured, medium to coarse-grained granite of the Cabeza de Araya Hercynian granitic intrusion. Higher grade uranium mineralisation (+0.1%U3O8) appears related to a structural zone in proximity to lithological boundaries within the host granite and/or fluctuations in a shallowly north dipping series of structures. Patchy episyenitic alteration has been observed. Much of the visible near surface mineralisation appears to be secondary autunite +/- torbanite while the deeper fracture-controlled mineralisation is primary coffinite and pitchblende associated with pyrite/marcasite in open fractures and zones of brecciation. The main Saguazal mineralisation occurs in a 1km zone near the ESE end of a 4 km long, radiometrically anomalous, shallowly dipping shear zone or thrust that strikes WNW-ESE and dips at about 300 to the NE. Within this zone the mineralised areas appear to be controlled by the intersections of steeply dipping fractures and/or undulations in the shear zone. As shown in Appendix 1, only about 1km of the anomalous shear zone has been drill tested to date. The apparently discontinuous nature of the mineralisation along strike, and complexity of the structural controls, will require thorough re-interpretation of the historical data in the light of results from the current programme before a more substantial drilling programme can commence. This work will be aimed at providing better definition of mineralised shoots and their trends, the role of supergene enrichment, and new target areas along the untested strike of the shear zone. The potential of other geophysical methods for drill targeting will also be assessed. The current drilling programme covers an area where CISA (a joint venture between ENUSA, the Spanish State uranium company, and COGEMA, the French company now called AREVA) concentrated most of their exploration drilling in the 1990's. CISA drilled few holes on the flanks of this main zone of mineralisation, where topographic and radiometric lows are associated with alluvium covered drainages (areas of 'Limited historical drilling' on the appended plan). CISA also tested other anomalous areas along strike, with some encouraging results as shown in Appendix 1. Best intersections from the previous CISA drilling are included as Table 2 below. TABLE 2.

The Berkeley drill holes were geologically and radiometrically logged before being sampled (1/4 core) at approximately 1m intervals (intervals varying from 0.5 to 2.0m based on geology) for most of the hole length. Duplicate 1/4 core samples and blank samples were included. Samples were assayed for total uranium by the Delayed Neutron Count (DNC) method at Activation Laboratories Limited in Ontario, Canada. Measured recoveries were good and averaged +97%. Minor core loss occurred in the surficial soil zone and in clay shear zones (mylonites), neither of which appear to be associated with uranium mineralisation. The technical content of this report has been reviewed and approved by Mr Peter Ellis, a Member of The Australian Institute Geoscientists and an employee of Berkeley Resources Limited. Mr Ellis 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'. Mr Ellis consents to the inclusion in the report of the matters based on his information in the form and context in which it appears.
