                          QUARTERLY ACTIVITIES REPORT
                             FOR THE QUARTER ENDED
                                 31 March 2007


Berkeley Resources Limited (AIM: BKY.L) is pleased to report on activities
during the quarter ended 31 March 2007.


  * Initial JORC compliant inferred resources of 11.9 million lbs of U3O8
    calculated for the Retortillo and Zona 7 deposits in the Salamanca I
    licence.

  * Targets defined for possible extensions of Retortillo mineralisation to
    the southeast and northwest.

  * Acquisition of eight new areas totalling 22,176 ha, covering extensions of
    favourable stratigraphy to the west and east of the Salamanca I licence,
    which increases the Company's groundholding to about 185,000 ha.

  * Drill targets defined at the Saguazal prospect at Caceres III, with
    testing to commence shortly.

  *  Substantial increase in drilling activity scheduled for June Quarter to
    test targets at Saguazal and Ojaranzo (Caceres VI) prospects, and infill and
    extensions of the Retortillo and Zona 7 deposits.

  * Mr Scott Yelland - a mining engineer with over 25 years experience
    managing mining operations around the world, including Spain, joined the
    Company as Chief Operating Officer.

  * Subsequent to the end of the quarter the Company completed a placement of
    12.5m shares at $1.85 per share, raising $23.1M (#9.65M), with
    institutional investors in North America, Europe and Australia.



1       EXPLORATION


SALAMANCA PROVINCE

Exploration in Salamanca Province focussed on preparation of resource estimates
for the Retortillo and Zona 7 uranium deposits, which were announced on the 8th
April, 2007. This work included:

  * continuation of the confirmatory drilling program at Retortillo, Zona 7
    and Mina Caridad;

  *  a critical review and assessment of historical data in the light of the
    confirmatory drill program results;

  * inclusion of all historical drill and assay data in a database;

  * conversion of historical downhole and core scintillometer radiometric logs
    to digital forms; and

  * conversion of radiometrics to equivalent radiometric grades in intervals
    with no chemical assays.

Eight new areas, totalling 22,176 ha, were acquired over favourable stratigraphy
in proximity to the Salamanca I tenements. This process also enabled the partial
conversion of the Salamanca II and III tenements to PI's.



Salamanca I

Confirmatory drilling of the Retortillo deposit continued with two diamond drill
rigs. Eighteen holes totalling 1880.65m were completed by the end of the
quarter. Single holes were also drilled into the Mina Caridad (CAR-001) and Zona
7 (Z7-001) prospects.

Drilling at Retortillo is continuing with hole RTO-022 currently in progress.

Details for these holes, including assays received from the first fourteen holes
(plus the Caridad and Zona 7 holes), are attached as Appendix I.

Results confirm the historical assays and radiometric equivalent grades from
surrounding JEN and ENUSA drilling and, in some instances, have increased both
grade and thickness. In addition, the more detailed geological information
acquired by Berkeley Resources has improved our understanding on the controls
influencing supergene and primary uranium mineralisation.

Notable assays include:

Retortillo:

RTO-001          19.4 to 40.8m - 21.4m @ 0.153% U3O8

RTO-002          26.0 to 39.5m - 13.5m @ 0.0307% U3O8

RTO-003          13.5 to 25.5m - 12.0m @ 0.0482% U3O8

RTO-004          33.7 to 42.0m - 8.3m @ 0.0706% U3O8

RTO-005          23.0 to 34.0m - 11.0m @ 0.0343% U3O8

RTO-010          33.0 to 40.2m - 7.3m @ 0.0426% U3O8


Zona 7:

Z7-001             0.0 to 8.5m - 8.5m @ 0.2841% U3O8



All holes were geologically and radiometrically logged before being sampled (1/4
core) at approximately 1m intervals (intervals varied from 0.5 to 1.5m based on
geology) for most of the section, from below surficial cover to the end of the
hole. Duplicate 1/4 core samples and blank samples were included and all samples
were assayed for total uranium by the Delayed Neutron Count (DNC) method at
Activation Laboratories Limited in Ontario, Canada. Check assays, at other
laboratories (including ENUSA), and acid soluble U assays and Th analyses are
being completed on selected samples, based on an assessment of the initial assay
data.

Measured core recoveries averaged >93% for the program, and also for each hole
with mineralisation (minor core loss occurred in some holes in the Tertiary
cover).

Historic drilling data for Retortillo has been fully evaluated in parallel with
the current drilling program. The resulting re-interpretation of the historic
JEN and ENUSA drill data has provided the basis of the 3D models of the
Retortillo and Zona 7 deposits and enabled the calculation of JORC compliant
resources.

The results of this calculation are summarised below:

Retortillo mineralisation appears to be hosted by the more carbonaceous shale
units which have been altered to kyanite/andalusite hornfels by nearby granite.
The importance of weathering is indicated by the association of mineralisation
with current and past water tables.

Structural controls are indicated by the fact that the northeastern limit of
thicker mineralisation appears fault-bounded with unmineralised,
chlorite-spotted shales to the northeast. Minor granite dykes also occur. Most
Retortillo uranium mineralisation occurs as torbernite, meta-autunite and
pitchblende, with gummites (oxidized pitchblende) in the Zona 7 area.
