AIM RELEASE  |  31 JANUARY 2013  |  ASX/AIM:BKY

DECEMBER 2012 QUARTERLY REPORT

Berkeley Resources Limited ('Berkeley' or the 'the Company') is pleased to present its quarterly report for the period ended 31 December 2012.

Highlights:

·     A positive Scoping Study was completed in November and confirmed the technical and economic viability of the Salamanca Project, including:

Ø Initial mine life of 11 years, including 7 years steady state operation, with strong potential to increase;

Ø Steady state annual production of 3.2 million pounds U3O8, with average annual production of 2.6 million pounds U3O8 over the life of mine;

Ø Life of mine average operating costs of US$25.65 per pound of U3O8;

Ø Upfront capital cost of US$83.6 million to deliver initial production. A further US$95.0 million, incurred in the second year of production and largely funded from operating cashflow, to achieve steady state operation.

·     Pre-Feasibility Study commenced, targeting completion in mid 2013. The study was awarded to Johannesburg based SENET, who will be assisted by SRK Consulting for mine design, Knight Piesold for heap design and Duro Felguera for the in-country project cost estimates.

·     The permitting process for Retortillo continued to advance with the Company's responses to the submissions received during the 30 day Public Information Period being delivered to the relevant authorities for their review and evaluation. The Nuclear Safety Council has also confirmed that all required information for the preparation of their compulsory report regarding the mining activities, and for the Initial Authorization of the process plant as a radioactive facility has been submitted.

·     The permitting process for Alameda was initiated with the submission to the relevant authorities of the Environmental Scoping Document and documentation associated with the application for reclassification (from rural to industrial use) of the affected surface land area.

The Directors are encouraged by the positive results of the Scoping Study, which clearly demonstrate the potential of the Salamanca Project to support a significant scale, long life uranium mining operation. Accordingly, the Company continues to focus on pursuing the ongoing exploration, appraisal and development of the Project in order to fulfil its strategic objective of becoming the next European uranium producer.

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

The Salamanca Project ('the Project') comprises the Retortillo, Alameda and Gambuta deposits plus a number of other Satellite deposits located in western Spain.

The results of a Preliminary Feasibility Study completed in early 2012 confirmed the technical and economic viability of a stand-alone project exploiting Retortillo, whilst Alameda formed part of a separate Feasibility Study completed in 2011.

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 ('the Study'). 

The Study was managed by Berkeley with input from a number of industry-recognised specialist consultants covering the key disciplines. The Study incorporated all of the information generated from the previous studies conducted on Retortillo and Alameda, as well as new, more recently completed drilling and metallurgical testwork data.

Scoping Study Results

Using only the current Mineral Resource Estimates for Retortillo and Alameda, which total 33.9 million pounds U3O8 (35.9 million tonnes at 429 ppm; 200 ppm U3O8 cut-off grade), as a base case scenario, the Project can support an average annual production of 3.2 million pounds of U3O8 during the seven years of steady state operation and 2.6 million pounds of U3O8 over a minimum eleven year mine life.  There is strong potential to increase the production profile and mine life through the exploitation of additional resources held by the Company (totalling 27.1 million pounds U3O8) and with ongoing exploration work.

The Study was based on open pit mining, heap leaching, a centralised process plant at Retortillo, and a remote ion exchange operation at Alameda, with loaded resin trucked to the centralised plant for final extraction and purification. The Company currently favours a contractor mining scenario. The average annual ore processing rate during steady state operation is 5.5 million tonnes. Operating cost estimates average US$25.65 per pound U3O8 over the life of mine.

The initial capital cost (nominally ± 30% accuracy) for the Project is 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, incurred in the second year of production and largely funded from operating cashflow, 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 the favoured mining contractor scenario (no mining fleet capital expenditure).

The Directors are encouraged by the positive results of the Scoping Study which clearly demonstrate the potential of the integrated Salamanca Project to support a significant scale, long life uranium mining operation. Further details on the Study are available in the Company's ASX Announcement dated 29 November 2012.

Pre-Feasibility Study

Following completion of the Scoping Study, Berkeley has commenced a Pre-Feasibility Study ('PFS') for the Salamanca Project. The PFS was awarded to the Johannesburg based company SENET, which will develop the study assisted by SRK Consulting for the mine design, Knight Piesold for the heaps design and Duro Felguera for the in-country project cost estimates.

The Company will undertake a more detailed mine scheduling and materials movement optimisation study, metallurgical testwork program and infrastructure assessment during the PFS phase, with the aim of identifying opportunities to further enhance the Project economics through capital and operating cost reductions. Resource infill and exploration drilling programs aimed at upgrading the resource classification and increasing the overall resource base are also underway.

The PFS will be carried out with a confidence level of ±20% for both the capital and operating cost estimates and will include the design details required to be submitted to the Spanish Nuclear Safety Council as part of the Authorization for Construction process for the processing plant.

Further metallurgical testwork will be carried out at the Mintek laboratories in Johannesburg and the Australian Nuclear Science and Technology Organisation ('ANSTO') facilities in Sydney.

The testwork program at Mintek aims to confirm the leaching efficiency for each phase of the mine schedule and test ore variability with respect to size distribution and geo-mechanical behaviour. The ANSTO testwork program is designed to facilitate the selection of the optimal backend of the process, with the performance of direct Solvent Extraction ('SX') and ammonium diuranate ('ADU') precipitation being compared to ion exchange ('IX') and UO4 precipitation.

Drilling and Mineral Resource Estimation

Drilling activity during the quarter included diamond drilling ('DD') at Retortillo and Alameda for resource definition, to provide drill core for metallurgical testwork and to provide drill core for geotechnical testwork. Details of the 1,836 metres of DD completed are summarised in Table 1.

Retortillo and Alameda

Diamond drilling continued during the December quarter at Retortillo and Alameda. This resource infill drilling is planned to facilitate further resource definition and to provide drill core for the next phases of metallurgical testwork being conducted as part of the feasibility studies. In addition, short diamond drill holes were drilled in areas of potential infrastructure sites to test the geotechnical characteristics of these areas.

The infill drilling at Retortillo was focussed on the first three phases of the current planned open pit mining schedule. The drilling results indicate that the mineralisation intersected was largely in line with the resource model predictions however, some drilling in the phase one mining area showed the mineralisation to be more erratic than predicted.

The results are based on down-hole gamma logging data and are presented as "equivalent" U3O8 grades or eU3O8. Some of the better results reported include 26 metres at 576 ppm eU3O8 from 37 metres depth in RTD341, 23 metres at 490 ppm eU3O8 from 32 metres depth in RTD343 and 16 metres at 1,079 ppm eU3O8 from 1 metre depth in RTD355 (Table 2).

At Alameda drilling was focused on the first two phases of the current planned open pit mining schedule. The drilling results indicate that the mineralisation intersected was in line with the resource model predictions. The drilling was also successful in demonstrating potential extensions to the current resource. Some of the better results reported include 14 metres at 924 ppm eU3O8 from 3 metres in ASD139, 11 metres at 2,469 ppm eU3O8 from 70 metres in ASD141 and 27 metres at 1,184 ppm eU3O8 from 85 metres in ASD143 (Table 3).

Regional Tenements

A program of regional water sampling has commenced in the region surrounding Retortillo. Preliminary results have highlighted the potential for this sampling methodology to detect areas of anomalous uranium associated with mineralisation. Further sampling and evaluation is underway to determine the effectiveness of this exploration method.

Gambuta

A Desktop Study undertaken on the Gambuta deposit, following the recent Mineral Resource Estimate ('MRE') update, has highlighted the significant potential of the deposit. Gambuta, 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). Following the positive results of the Desktop Study, initial metallurgical testwork will be undertaken during the March quarter to determine the leaching characteristics of the mineralisation.

Permitting

The permitting process at Retortillo continues to advance. During the quarter, the Company's responses to the submissions received during the 30 day Public Information Period (completed in mid September) were delivered to the relevant authorities for their review and evaluation. Follow-up discussions regarding appropriate mitigation measures have been held with the authorities. It is anticipated that the Project will be raised for mining and environmental approval within the first half of 2013.

The Initial Authorisation for the process plant as a radioactive facility is well advanced. The Nuclear Safety Council has informed Berkeley that they have all required information for the preparation of their compulsory report regarding the mining activities, and also for the Initial Authorization of the process plant as a radioactive facility. Both are anticipated during the June quarter of 2013.

Ancillary permits, such as those associated with water and roads, are also currently being advanced. Discussions have been held with the relevant authorities (including the Water Authority and Roads Department) and the required documentation submitted.  

At Alameda, the Environmental Scoping Document and the documentation associated with the change of the zoning of rural land into that suitable for industrial purposes were submitted in November and December, respectively. The Exploitation Plan, Rehabilitation and Closure Plans and documents related to Radiological Protection will be prepared based on the design developed as part of the PFS, targeting submission of these documents by mid 2013.

CORPORATE

At 31 December 2012 the Company had cash reserves of A$32.5 million.

In November 2012, Señor Jose Ramon Esteruelas retired as a Non-Executive Director. Señor Esteruelas had been a Director of Berkeley since November 2006 and played a key role as the Company moved from explorer to developer in Spain.
