JUNE 2013 QUARTERLY REPORT

Berkeley Resources Limited ('Berkeley' or the 'the Company') is pleased to present its quarterly report for the period ended 30 June 2013. The Company's primary focus during the period continued to be the advancement of the Salamanca Project located in Spain.

Highlights during the quarter include:

·; Substantial progress made on the Pre-Feasibility Study ('PFS') for the Salamanca Project

o The PFS, which is focussed on the integrated development of Retortillo and Alameda, is being led by SENET, assisted by SRK Consulting for mine design, Knight Piésold for heap design, Duro Felguera for project cost estimates and URS for environmental management.

o The metallurgical testwork program, aimed at confirming leaching efficiencies and reagent consumptions, testing ore variability and geomechanical properties of both Retortillo and Alameda, was completed at Mintek's laboratory in Johannesburg.

o Final uranium recovery data is pending however, the results received to date have shown optimal recovery performance at crush sizes of 40mm and 12mm for Retortillo and Alameda respectively, acid consumption below 20 kg/t for both deposits, and confirmed heap stacking heights of six metres are appropriate.

o Mining waste characterisation testwork, geotechnical testwork, hydrogeology studies, an infrastructure assessment, heap leach pad design work and the majority of the engineering and design activities were completed.

o The PFS remains on track for completion in the September quarter.

·; Completed resource drilling at Retortillo

o An infill drilling program, aimed at upgrading the classification of the portion of the current Inferred Resource that falls within the open pit into the Indicated category was completed.

o In total, 67 reverse circulation ('RC') holes for approximately 4,400 metres were drilled.

o Significant intersections were recorded at shallow depths (from surface to a maximum depth of 88 metres), with thicknesses up to 21 metres.

o The drilling has also confirmed that the mineralisation extends a further 200 metres to the northwest beyond the northern limit of the current resource boundary and it remains open.

o Select intercepts include 20 metres @ 657 ppm, 8 metres @ 1,207 ppm, 9 metres @ 789 ppm, 21 metres @ 334 ppm, 9 metres @ 574 ppm and 14 metres @ 359 ppm U3O8.

o The data obtained from the drilling program will form the basis for a revised MRE for Retortillo which will be completed in the September quarter and incorporated into the PFS.

·; Positive progress on the permitting of Retortillo

o The evaluation of the favourable recommendation report provided by the Environmental Technical and Executive Committees at the Salamanca provincial level following their review of the Company's Environmental Impact Assessment ('EIA') has continued at the Regional Government of Castilla y León head office in Valladolid.

o The Environmental Licence is pending formal approval at the Regional Government level and further release in the Official Gazette. The Environmental Licence, along with approval of Berkeley's Exploitation and Reclamation and Closure Plans, are prerequisites for the grant of the Exploitation Concession (Mining Licence).

·; Continued Scoping Study on the Gambuta deposit

o Geotechnical evaluation, preliminary open pit optimisation and mine design, preliminary heap leach pad design, and a site layout and infrastructure assessment are all underway.

o The scope of work also includes initial metallurgical testwork on a sample, including bond crushability and bond abrasion tests, diagnostic leach tests, mineralogy and column leach tests at various crush sizes. A 330 kilogram representative sample has been transported to Mintek's laboratory in Johannesburg and is currently being prepared for the testwork program.

·; Completed exploration drilling at Retortillo Satellite Deposit

o A drilling program comprising 18 RC holes for approximately 1,100 metres was carried out at the largest of the Retortillo Satellite Deposits, Zona 7. Final assay results are pending.

o A review of all available data for the tenements surrounding the Company's existing resources identified the potential extension of Zona 7 to the southwest as a high priority drill target.

o Zona 7 is located within 10 kilometres of the proposed location of the centralised processing plant at Retortillo and currently hosts an Inferred MRE of 3.6 million pounds of U3O8.

OPERATIONS

Berkeley Resources Limited ('Berkeley' or 'the Company') is a uranium exploration and development company with a quality resource base in Spain. Berkeley is currently focused on advancing its wholly owned flagship Salamanca Project.

Salamanca Project

Berkeley's flagship Salamanca Project comprises the Retortillo, Alameda and Gambuta deposits, plus a number of other Satellite deposits located in western Spain.

In November 2012, the Company completed an initial assessment of the integrated development of Retortillo and Alameda and reported the results of the Scoping Study, which clearly demonstrated the potential of the Salamanca Project to support a significant scale, long life uranium mining operation.

Using only the current Mineral Resource Estimates ('MRE') for Retortillo and Alameda, as a base case scenario, the Scoping Study showed the Project can support an average annual production of 3.2 million pounds of U3O8 during the 7 years of steady state operation and 2.6 million pounds of U3O8 over a minimum 11 year mine life. Operating cost estimates (C1 cash costs) average US$25.65 per pound U3O8 over the life of mine. The initial capital cost (nominally ± 30%) for the Project was estimated at US$83.6 million. This cost is inclusive of all mine, processing, infrastructure and indirect costs required to develop and commence production at Retortillo. A further US$95.0 million of capital is required to develop Alameda and achieve steady state operation. The Project's capital cost reflects the excellent existing infrastructure, use of heap leaching as the preferred processing route, and contractor mining.

Following completion of the Scoping Study, Berkeley commenced a Pre-Feasibility Study ('PFS') for the Salamanca Project focussed on the development of Retortillo and Alameda.

The Company has also advanced the evaluation of the Gambuta deposit to the Scoping Study stage. Gambuta will ultimately be integrated with Retortillo and Alameda, with a view to potentially increasing the production scale and/or mine life of the Salamanca Project.

Pre-Feasibility Study

The PFS for the Salamanca Project, which is focussed on the integrated development of Retortillo and Alameda, continued to be the Company's key focus during the quarter. The Study is progressing well and remains on schedule for completion in the September quarter

The PFS is being led by Johannesburg based SENET, assisted by SRK Consulting for mine design, Knight Piesold for heap design, Duro Felguera for in-country project cost estimates and URS for environmental management.

Metallurgical Testwork

A comprehensive metallurgical testwork program, aimed at confirming the leaching efficiency for each phase of the mine schedule and testing ore variability with respect to size distribution and geo-mechanical behaviour at both Retortillo and Alameda, has been completed at the Mintek laboratories in Johannesburg during the quarter.

Whilst not all of the analytical data and testwork results have yet been received, the key outcomes of the work program to-date include:

·; Column stacking tests performed on Retortillo fresh feed and residues indicate that all samples have a minimum porosity of 30%, giving a bulk density below 1.85 at a stacking height of 10 metres. At a 10 metre stacking height the saturated hydraulic conductivities are above the target of 100 times the target application rate (1000 L/m2/hr). This result confirms that the heap stacking heights of six metres can be used in the PFS (consistent with the Scoping Study assumption).

·; Stacking tests performed on Alameda fresh feed and residues indicate that the material is substantially more competent than the Retortillo material. Degradation and fines generation during leaching is minimal, suggesting that little change to the hydraulic properties will occur during the leach cycle. The residue samples at -12mm crush size maintained saturated hydraulic conductivities above the target (1000 L/m2/hr) at stacking heights of 10 metres.

·; Hydrodynamic column tests performed on Retortillo residues at a bulk density targeting a six metre stack height achieved heap saturation of below 50% at irrigation rates of 10 L/m2/hr. The maximum target for geotechnical stability is 85%-75% which highlights that the samples performed well at this bulk density. As noted above, the Alameda ore is more competent hence no instability issues are envisaged.

·; Although final recovery data is not yet available, the results received to date have shown optimal metallurgical recovery performance at the crush sizes of 40mm and 12mm for Retortillo and Alameda respectively. A direct relationship between recovery and crush size has been observed in all tests at Alameda, whilst recovery at Retortillo has been shown to be relatively insensitive to crush size. Based on the preliminary results, uranium recoveries are anticipated to be consistent with the results of previous testwork campaigns.

·; Acid consumption reported during the testwork was below 20 kg/t for both deposits.

Other PFS Testwork and Activities

Other PFS work carried out during the quarter included:

·; Waste characterisation testwork results have shown the properties of the three types of mining waste to be consistent with those of previous evaluations. Mining waste has been characterised and classified as follows:

Ø Oxide waste ('inert waste') - an inert waste that can be handled as a typical mining waste

Ø Acid Rock Drainage ('ARD') - potential acid generator due to a marginal sulphide content

Ø Natural Occurring Radioactive Materials ('NORM') - rock containing very low residual uranium below the mining cut-off grade

·; Geotechnical testwork was conducted on drill core from the Retortillo deposit and from the proposed sites of key infrastructure e.g. heap leach pads, waste dumps, at both Retortillo and Alameda. The results of the testwork have been reviewed by SRK and their recommendations applied in the design of the open pits (slope angles etc.) and by the civil engineers for the siting of infrastructure.

·; Hydrogeological models were updated with new information relating to dewatering of the open pits. The operational water balance was subsequently updated and highlighted a net reduction in the volume of water required to be sourced from local water courses at Retortillo. The modelling confirmed that no water is required to be sourced from local water courses at Alameda.

·; The majority of the engineering and design activities, including the project site lay-out review were completed. General layouts were optimised and completed including the general arrangements of the different areas. Based on the column stacking testwork results and the requirements of the ripios backfilling schedule, the heap leach pad designs were finalised. The heap stack height design was confirmed at two, six metre lifts for both Retortillo and Alameda.

·; Trafficability tests were carried out on the residues from heap leaching, with the results demonstrating that the ripios can be readily managed by either trucking or conveying.

Resource Drilling

The current MREs for Retortillo and Alameda have 61% and 95% of the total resource respectively classified into the Indicated Resource category (refer June 2012 Quarterly Report and Table 1). The MRE's were prepared by Berkeley in July 2012 and are reported in accordance with the JORC Code (2004).

Table 1 - Summary of Mineral Resource Estimates

An infill drilling program, aimed at upgrading the classification of a significant portion of the current Inferred Resource at Retortillo to the Indicated category, was completed during the quarter. In total, the resource infill program comprised 67 reverse circulation ('RC') drill holes for 4,382 metres.

Assay results returned from the RC drill holes were largely in line with expectations based on the current resource model, with some local variability observed. Significant intersections have been recorded at shallow depths (from surface to a maximum depth of 88 metres), with thicknesses up to 21 metres. The drilling has also confirmed that the mineralisation extends a further 200 metres to the northwest beyond the northern limit of the current resource boundary and it remains open. Select intercepts from the drilling program include:

Details of the drilling completed during the quarter and calendar year-to-date are summarised in Appendix A. The collar positions, dips, azimuths, depths and significant intersections of the Retortillo RC drilling program holes are provided in Appendix B.

The data obtained from this RC drilling program will form the basis for a revised MRE for Retortillo, which aims to upgrade the classification of the portion of the current Inferred Resource that falls within the optimised pit outline from the Scoping Study into the Indicated category. The revised MRE will be completed in the September quarter and incorporated into the PFS.

Gambuta

The Gambuta deposit, which is located approximately 145 kilometres southeast of Retortillo, has an Inferred MRE of 12.7 million tonnes at 394 ppm U3O8 for a total of 11.1 million pounds of U3O8 at a 200 ppm U3O8 cut-off grade (refer September 2012 Quarterly Report).

The geometry, average thickness and depth of the mineralisation make it amenable to shallow open pit mining with a low ore to waste strip ratio.

Following the positive results of a Desktop Study completed on Gambuta, the Company has advanced the evaluation of the deposit to the Scoping Study stage. The conceptual approach is based on open pit mining, heap leaching, and a remote ion exchange operation, with the loaded resin being trucked to the proposed centralised plant at Retortillo for final extraction and purification.

A geotechnical evaluation which includes relogging of drill core, preliminary open pit optimisation and mine design, preliminary heap leach pad design, and a site layout and infrastructure assessment have all commenced during the quarter and are ongoing.

The scope of work also includes initial metallurgical testwork on a 330kg representative sample, including bond crushability and bond abrasion tests, diagnostic leach tests, mineralogy and column leach tests at various crush sizes. The bulk sample has been transported to Mintek's laboratory in Johannesburg and is currently being prepared for the testwork program which will be run during the September quarter.

Exploration

A comprehensive review of all available data for the tenements surrounding the Company's existing resources, undertaken in early 2013, identified the potential extension of Zona 7 to the southwest as a priority drill target.

Zona 7 is the largest of the Retortillo Satellite Deposits and currently hosts an Inferred MRE of 3.9 million tonnes averaging 414 ppm U3O8 for a contained 3.6 million pounds of U3O8 at a 200 ppm U3O8 cut-off grade (refer ASX June 2012 Quarterly Report). It is located within 10 kilometres of the proposed location of the centralised processing plant at Retortillo.

During the quarter, a reverse circulation ('RC') drill program comprising 18 holes for 1,133 metres was carried out on an approximately 400 metre by 100 metre grid to test this priority target. Final assay results are pending.

Permitting

The permitting processes for Retortillo, Alameda and Gambuta continued to be advanced during the quarter.

The administrative process relating to the evaluation of the favourable recommendation report provided by the Environmental Technical and Executive Committees at the Salamanca provincial level following their review of the Company's Environmental Impact Assessment ('EIA') and associated documentation has continued at the Regional Government of Castilla y León head office in Valladolid.

The Environmental Licence (Declaration of Environmental Impact) is now pending formal approval at the Regional Government level and further release in the Official Gazette. The Environmental Licence, along with approval of Berkeley's Exploitation and Reclamation and Closure Plans, are prerequisites for the grant of the Exploitation Concession (Mining Licence).

There has been no change to the status of the Initial Authorisation for the process plant as a radioactive facility. The Nuclear Safety Council ('NSC') informed Berkeley during the prior quarter that they had all required information for the preparation of their compulsory report regarding the mining activities, and also for the Initial Authorisation of the process plant as a radioactive facility. Both have been drafted and are pending formal approval by the NSC Board.

The Exceptional Authorisation for Land Use (application for reclassification from rural to industrial use) of the affected surface land area at Retortillo has been approved by the relevant authorities at the Urbanism and Town Planning Department of Salamanca, subject to the issuance of the Environmental Licence.

The permitting process for Alameda commenced late in 2012 with the submission to the regulatory authorities of the Environmental Scoping Document and documentation associated with the Exceptional Authorisation for Land Use.

Preparation of the documents required for the next phase of permitting at Alameda, including the Exploitation Plan, Reclamation and Closure Plans, and the EIA is also well advanced. These documents will be completed and submitted to the relevant authorities during the September quarter.

The documentation associated with the Exceptional Authorisation for Land Use was lodged for Public Information in February and the 20 day Public Information Period ('PIP') completed in March. The Company is currently preparing responses to the comments raised during the PIP and will also include references to any new data that has been incorporated into the Alameda Exploitation Plan, Reclamation and Closure Plans, and EIA in its submission.

The Company has started to receive feedback from the relevant authorities following submission of the Environmental Scoping Document for Gambuta in March. A complete list of comments is expected in the coming months, and once received; Berkeley will prepare responses to the comments to be included in the EIA as required.

CORPORATE

At 30 June 2013 the Company had cash reserves of A$27.7 million. The Company continues to maintain a strong focus on cost control across all areas of the business.

In April 2013, Shareholders approved Berkeley's Performance Rights Plan. The Plan is designed to reward superior performance based on materially improved Company performance in terms of growth in the value of the Company and resulting increases in Shareholder value. The Plan is intended to replace the existing Employee Share Option Plan which was most recently approved by Shareholders in September 2011. Following approval of the Plan, 4.67 million Performance Share Rights were issued on 3 May 2013.

On 15 May 2013, 11.89 million Listed Options expired unexercised.
