BERKELEY RESOURCES LIMITED 

AIM RELEASE  |  26 NOVEMBER 2014  ED BY 43% TO 88.2 Mlbs U₃O₈ FOLLOWING SUBSTANTIAL INCREASE IN ZONA 7 RESOURCE

Highlights:

·     Zona 7 Mineral Resource Estimate ('MRE') increased to 30.1 Mlbs U₃O₈ (previously 3.6 Mlbs);

·     Average grade of the MRE increased by 42% to 589 ppm U₃O₈;

·     90% of the MRE within 50 metres of surface;

·     Zona 7 now the largest deposit within the Salamanca Project;

·     Salamanca Project total resource base increased by 43% to 88.2 Mlbs U₃O₈;

·     The successful exploration drilling at Zona 7 highlights the exploration and resource growth
 potential of the broader Salamanca Project; and

·     Scoping Study commenced to determine the optimum integration of Zona 7 with the development
 of Retortillo and Alameda, thereby potentially increasing the scale and/or mine life of the Project.

Berkeley Resources Limited ('Berkeley' or 'the Company') is pleased to announce an updated Mineral Resource Estimate ('MRE') for Zona 7, the largest of the Retortillo Satellite Deposits and part of the Company's Salamanca Project in Spain.

This Inferred MRE has been estimated at 23.2 million tonnes averaging 589 ppm U₃O₈ for a contained 30.1 million pounds of U₃O₈ at a lower cut-off grade of 200 ppm U₃O₈.

The updated MRE incorporates the drilling results from the successful 2013 and 2014 campaigns which essentially doubled the strike length of the Zona 7 mineralisation, extending it by 1,200 metres to the southwest. Significant shallow, high grade intersections were recorded and the mineralisation remains open along the north-western margin and along strike. Both areas will be targeted in subsequent drilling campaigns.

Given the significant scale, high grade and shallow depth of the Zona 7 deposit, the Company has advanced its evaluation to the Scoping Study stage. A Scoping Study has commenced with completion scheduled for the March quarter of 2015.

As Zona 7 is located within 10 kilometres of the proposed centralised processing plant at Retortillo, there is scope to integrate it with planned development of Retortillo and Alameda, and potentially increase the level of production and/or mine life of the Salamanca Project.

Prospect Location and Geology

Zona 7 is the largest of the Retortillo Satellite Deposits and part of the Berkeley's Salamanca Project (the 'Project') in central-western Spain.

The Company completed a Pre-Feasibility Study ('PFS') for the integrated development of the Retortillo and Alameda deposits in late 2013. The results of this PFS demonstrated the potential of the Salamanca Project to support a significant scale, long life uranium mining operation (refer Announcement dated 26 September 2013). Following completion of the PFS, Berkeley has commenced a Definitive Feasibility Study ('DFS') for the Project.

Significantly, the Zona 7 deposit is located within 10 kilometres of the proposed centralised processing plant at Retortillo. Given the PFS was based solely on the Mineral Resource Estimates ('MRE's') for Retortillo and Alameda, it is considered a base case scenario and Zona 7 will ultimately be integrated with Retortillo and Alameda, with a view to potentially increasing the level of production and/or mine life of the Project.

Zona 7 is a vein type uranium deposit hosted in a sequence of fine grained metasediments which are overlain by a conglomerate unit and adjacent to a granite intrusive. The mineralised envelope is interpreted to be sub-horizontal to shallowly dipping, and occurs from surface and to maximum depth of approximately 90 metres. The style of the uranium mineralisation includes veins, stockwork and disseminated mineralisation in joint/fracture filling associated with brittle deformation. The uranium mineralisation occurs both within the partially weathered zone and fresh rock. Uraninite and coffinite are the primary uranium minerals. Secondary uranium mineralisation is developed in 'supergene-like' tabular zones corresponding to the depth of weathering.

Drilling

Three phases of drilling, totalling 215 holes for 12,706 metres, have been carried out at Zona 7 (Table 1).

The initial phase relates to historical drilling conducted during the period from the 1960's to 1980's by Junta de Energía Nuclear ('JEN'), a Spanish state run company. A total of 72 diamond ('DD') holes were drilled for 4,024 metres (32% of total drilling). 

The second phase of drilling was conducted in 2007 and 2008 by Berkeley. During this period, 66 reverse circulation ('RC') holes and 9 DD holes for a combined 4,240 metres (33% of total drilling) were drilled to test the area of mineralisation defined by the historical drilling.  

A third phase of drilling has been completed during 2013 and 2014. The potential extension of Zona 7 to the southwest towards Las Carbas was identified as a priority drill target following a review of all available data for the regional tenements surrounding the existing resources in late 2012. An 18 hole, 1,128 metre RC drill program was subsequently completed in mid-2013 to test this priority target. This drilling, which was carried out on an approximately 400 metre by 100 metre grid, resulted in the mineralised zone being extended a further 1,200 metres to the southwest of the previous resource area. The recently completed 2014 drilling program, which comprised 45 RC holes for 2,923 metres and five DD holes (including one redrill) for 391 metres, was aimed at infilling the Zona 7 extension on a notional 100 metre by 100 metre grid.

Table 1: Summary of drill holes used in the resource update

Drill Type	Pre-2007		2007-2008		2013-2014		Total
	Holes	Metres	Holes	Metres	Holes	Metres	Holes	Metres	%
Reverse Circulation	-	-	66	3,579	63	4,051	129	7,630	60
Diamond Core	72	4,024	9	661	5	391	86	5,076	40
Total	72	4,024	75	4,240	68	4,442	215	12,706	100

The majority of the Berkeley drilling was undertaken on a 100 metre by 100 metre grid, with section lines orientated approximately northwest-southeast across the interpreted strike of the mineralisation. Some of the historical drilling was completed on a closer spaced 35 metre x 35 metre grid. The majority of the drill holes are vertical.

RC drill samples were collected over one metre intervals and these samples were split to achieve 0.7 -1.0 kilogram samples which were sent to external laboratories for sample preparation and uranium analysis. Sample splitting employed either a riffle splitter or a cone and quarter method. Field tests of the two methods found that both produce representative samples. Sampling of diamond core was completed using 0.25 metre to 1.85 metre sample lengths. For the historical DD, whole core samples were used whilst for the Berkeley DD, core was cut to achieve either half or quarter core samples. DD core recoveries typically exceed 90%.

Sample preparation of all drill samples involved oven drying, crushing and pulverising to achieve a grind size of 85% passing 75μm. Sample pulps from the Berkeley drilling were analysed for uranium using either of the delayed neutron counting ('DNC') or pressed powder x-ray fluorescence ('XRF') methods. Historical drilling samples were analysed for uranium using the XRF, atomic absorption spectrometry ('AAS') or fluorometric methods. Berkeley sample batches were prepared with standards, blanks and field duplicates inserted prior to dispatch to the laboratory. Approximately 15-20% of all samples relate to quality control. There is no data available regarding quality assurance and quality control ('QAQC') from the historical drilling.

All Berkeley drill holes were down-hole gamma logged and 'equivalent' U₃O₈ grades or eU₃O₈ grades calculated from down-hole gamma emissions recorded using standard gamma logging systems, with appropriate QAQC procedures in place. The gamma response was converted to an estimated uranium grade by correcting for radon, hole diameter, and air/water, and a deconvolution filter was applied to reflect the nature of mineralisation. Assay data is the primary method for grade estimation in the resource modelling process and eU₃O₈ data was only used where there was no assay data available.

Resource Model

Geological interpretation was undertaken on 100 metre spaced sections with wireframes interpreted around the mineralised intercepts taking into account geology and structure where possible. These sectional interpretations were joined to create a series of three dimensional ('3D') mineralised wireframes (domains) that showed continuity of grade along and across strike.

Topographic control is based on a digital terrain model ('DTM') with sub metric accuracy sourced from the Spanish Geographical Institute (Instituto Geográfico Nacional). The DTM was verified from drill hole collar surveys completed by a qualified surveyor using a differential global positioning system ('DGPS').

A volume block model was constructed using a parent block size of 25 metres (X) by 25 metres (Y) by 6 metres (Z) with cells being permitted to split once in any direction where bounding surfaces of the mineralised wireframes were intersected.

Basic statistics and variogram modelling was completed using one metre sample composites within each domain. As most sample populations had significant positive skewness, grade top cuts were applied nominally approximating the 97.5 population percentile. The domains were assessed independently and a top cut grade was applied to the drilling data for each domain, up to a maximum of 5,000 ppm U₃O₈. 

Grade Estimate

The uranium grade was estimated into the parent cells using Ordinary Kriging ('OK'). Variography was used to derive appropriate orientation and weighting factors employed by the Kriging algorithm. Suitable sample search distances, minimum and maximum sample numbers required to make a grade estimate and search ellipse anisotropy to honour the mineralisation trends were derived. These parameters were selected to ensure that the resource model honours both the global and local grade distribution of the uranium mineralisation.

Bulk density values were derived from over 300 solid‐fluid pycnometer measurements. In situ dry bulk densities were applied to all blocks in the resource model based on the degree of weathering as follows: 2.33 tonnes per cubic metre for completely weathered material, 2.43 tonnes per cubic metre for partially weathered material and 2.66 tonnes per cubic metre for fresh rock.

Validation of the models included visual inspection of the grade distribution compared to the drill hole data, comparison of block model and drill hole statistics and creation and assessment of swath plots. Overall the grade estimate showed a good representation of the drill hole data for the resource.

Mineral Resource Estimate

The MRE for Zona 7 has been updated, incorporating additional drilling and sampling information from the 2013 and 2014 drilling campaigns.

The MRE has been classified as Inferred based on the guidelines recommended in the JORC Code (2012). When classifying the resource estimate the following has been considered:

·     Quality and reliability of raw data (sampling, assaying, surveying);

·     Confidence in the geological interpretation;

·     Number, spacing and orientation of intercepts through mineralised zones;

·     Knowledge of grade continuities gained from observations and geostatistical analyses; and

·     The potential prospect for eventual economic extraction.

The MRE is reported at a lower cut-off grade of 200 ppm U₃O₈ (Table 2), along with estimates showing the range of U₃O₈ cut-off grades that would span the range applicable to open pit mining (Table 3).

Comparison with previous Mineral Resource Estimate

An Inferred MRE of 3.9 million tonnes averaging 414 ppm U₃O₈ for a contained 3.6 million pounds of U₃O₈ at a lower cut-off grade of 200 ppm U₃O₈ was previously reported for Zona 7 in June 2012 (refer June 2012 Quarterly Report dated 31 July 2012). Since then the following significant changes have occurred:

·     An additional 63 RC holes for 4,051 metres and five DD holes for 391 metres were drilled during 2013 and 2014. This represents an approximately 54% increase in the amount of drilling data available for incorporation in the MRE;

·     Mineralisation was extended ~1,200 metres along strike to the southwest by drilling; and

·     Thick, high grade intersections were recorded at shallow depths in the 2013 and 2014 drilling.

Table 4 presents a summary of the differences between the current and previous MRE's and highlights the significant increase in tonnes, grade and contained uranium as a consequence of the delineation of the zone of thick, high grade mineralisation extending well beyond (~1,200 metres) the previous resource boundary at Zona 7.

Summary of Resource Estimate and Reporting Criteria

This announcement has been prepared in compliance with JORC Code 2012 Edition and the ASX Listing Rules. The Company has included in Appendix A, the Table 1 Checklist of Assessment and Reporting Criteria for Zona 7 as prescribed by the JORC Code (2012) and the ASX Listing Rules.

The following is a summary of the pertinent information used in the MRE.

Geology and Geological Interpretation

Zona 7 is a vein type uranium deposit hosted in a sequence of fine grained metasediments which are overlain by a conglomerate unit and adjacent to a granite intrusive. The mineralised envelope is interpreted to be sub-horizontal to shallowly dipping, and occurs from surface and to maximum depth of approximately 90m. The style of the uranium mineralisation includes veins, stockwork and disseminated mineralisation in joint/fracture filling associated with brittle deformation. The uranium mineralisation occurs both within the partially weathered zone and fresh rock. Uraninite and coffinite are the primary uranium minerals. Secondary uranium mineralisation is developed in 'supergene-like' tabular zones corresponding to the depth of weathering.

Drilling and Sampling Techniques

The MRE is based upon data obtained from three phases of drilling (historical 1960's to 1980's, 2007-2008 and 2013-2014) totalling 215 holes for 12,706m. The drilling comprised 86 diamond holes and 129 RC holes.

The majority of the Berkeley drilling was undertaken on a 100m by 100m grid, with section lines orientated approximately northwest-southeast across the interpreted strike of the mineralisation. Some of the historical drilling was completed on a closer spaced 35m x 35m grid. The majority of the drill holes are vertical.

Berkeley drill hole collar locations were surveyed by qualified surveyors using standard DGPS equipment achieving sub decimetre accuracy in horizontal and vertical position. Berkeley down-hole surveys were undertaken using a Geovista down-hole deviation probe. Measurements were taken every 1cm down hole and averaged every 10m. All diamond and RC drill samples were geologically logged, with all relevant data being recorded. Diamond core was also geotechnically logged. Berkeley core boxes and samples and RC samples and chip trays were photographed for future reference.

Diamond core was quarter or half cut and sampled on 0.25-1.85m intervals. RC samples were collected over 1m intervals and split in the field using two riffle splitters in cascade or a cone and quarter method to provide an approximately 3-5kg sample. Samples were further split in the core shed using a riffle splitter such that 0.7-1kg samples were sent to external laboratories for preparation and analysis. Quality assurance procedures were employed, including the use of standards, blanks and duplicates.

Down-hole gamma logging was undertaken for all probe accessible holes drilled by Berkeley to provide eU₃O₈ data. The down-hole gamma response was converted eU₃O₈ by correcting for radon, hole diameter, air/water and a deconvolution filter was also applied. eU₃O₈ data was only considered in the mineral resource estimation process when chemical assay data was not available.

Bulk density values were derived from over 300 solid‐fluid pycnometer measurements. In situ dry bulk densities were applied to all blocks in the resource model based on the degree of weathering.

Sample Analysis Method

Sample preparation of all drill samples involved oven drying, crushing and pulverising to achieve a grind size of 85% passing 75μm. Sample pulps from the Berkeley drilling were analysed for uranium using either of the DNC or pressed powder XRF methods. Historical drilling samples were analysed for uranium using the XRF, AAS or fluorometric methods.

Resource Estimation Methodology

Surpac software was used for geological modelling, block modelling, grade interpolation, MRE classification and reporting. Sectional geological interpretations were joined to create a series of 3D mineralised wireframes (domains) that showed continuity above a grade of 100 ppm U₃O₈. Statistical and geostatistical variogram modelling was used to determine appropriate parameters for estimation of uranium grade using Ordinary Kriging.

Cut-off Grades

The MRE has been reported using a lower cut-off grade of 200 ppm U₃O₈, which is consistent with the grade used to report previous MRE's for this style of mineralisation.

Mining and Metallurgical methods and parameters

No mining studies or metallurgical testwork have been undertaken however, feasibility studies have been completed for deposits hosted in similar geological settings in close proximity to the Zona 7 deposit. Based on the results of these studies, it is assumed that the Zona 7 MRE could potentially be extracted using open pit mining methods, with the recovery of uranium through the application of acid heap leach methods.

Resource Classification Criteria

The MRE has been classified and is reported as Inferred based on guidelines recommended in the JORC Code (2012). The reported MRE has been classified with consideration of the quality and reliability of the raw data, the confidence of the geological interpretation, the number, spacing and orientation of intercepts through the mineralised zones, and knowledge of grade continuity gained from observations and geostatistical analysis. There is adequate mining, metallurgy and processing knowledge from feasibility studies on geologically similar deposits within the region to imply reasonable prospects for eventual economic extraction.

Glossary of Key Terms

'Competent Person' is a minerals industry professional who is a Member or Fellow of The Australasian Institute of Mining and Metallurgy, or of the Australian Institute of Geoscientists, or of a 'Recognised Professional Organisation' (RPO), as included in a list available on the JORC and ASX websites.

'Inferred Mineral Resource' is that part of a Mineral Resource for which quantity and grade (or quality) are estimated on the basis of limited geological evidence and sampling. Geological evidence is sufficient to imply but not verify geological and grade (or quality) continuity. It is based on exploration, sampling and testing information gathered through appropriate techniques from locations such as outcrops, trenches, pits, workings and drill holes.

'Indicated Mineral Resource' is that part of a Mineral Resource for which quantity, grade (or quality), densities, shape and physical characteristics are estimated with sufficient confidence to allow the application of Modifying Factors in sufficient detail to support mine planning and evaluation of the economic viability of the deposit.

'JORC'means the Joint Ore Reserves Committee of the Australasian Institute of Mining and Metallurgy, Australian Institute of Geoscientists and Mineral Council of Australia.

'JORC Code (2012)' means the 2012 edition of the Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves.

'Mineral Resource' means a concentration or occurrence of solid material of economic interest in or on the Earth's crust in such form, grade (or quality), and quantity that there are reasonable prospects for eventual economic extraction. The location, quantity, grade (or quality), continuity and other geological characteristics of a Mineral Resource are known, estimated or interpreted from specific geological evidence and knowledge, including sampling. Mineral Resources are sub-divided, in order of increasing geological confidence, into Inferred, Indicated and Measured categories.

Appendix A: JORC Code, 2012 Edition - Table 1 report

Section 1 Sampling Techniques and Data

(Criteria in this section apply to all succeeding sections.)

Criteria	JORC Code explanation	Commentary
Sampling techniques	Nature and quality of sampling (eg cut channels, random chips, or specific specialised industry standard measurement tools appropriate to the minerals under investigation, such as down hole gamma sondes, or handheld XRF instruments, etc). These examples should not be taken as limiting the broad meaning of sampling.	Berkeley DD core was sampled using 0.25-1.85m intervals in the mineralised zones, including areas of internal low grade or waste. In addition, the sampling was extended 3-5m up and down hole from the interpreted mineralised zone. Half or quarter core was used for sampling. Berkeley reverse circulation (RC) drill samples are collected over 1m intervals and split on site using two riffle splitters in cascade to provide an approximately 3-5kg sample. In rare cases, wet samples are split using a cone and quarter method. Field tests show that both methods produce representative samples. Junta de Energía Nuclear (JEN) diamond drill (DD) core was sampled using 0.25m, 0.50m and 1.00m intervals in the mineralised zones, with 0.25m intervals being the most frequent sample length.
	Include reference to measures taken to ensure sample representivity and the appropriate calibration of any measurement tools or systems used.	Berkeley sampling protocols include the insertion of standards and blanks into the sample stream to assess the accuracy, precision and methodology of the external laboratories used. In addition, field duplicate samples are inserted to assess the variability of the uranium mineralisation. Approximately 15-20% of all samples relate to quality control. In addition, the laboratories undertake their own duplicate sampling as part of their internal Quality Assurance/Quality Control (QA/QC) processes. Examination of the QA/QC sample data indicates satisfactory performance of field sampling protocols and assay laboratories providing acceptable levels of precision and accuracy. Berkeley drill hole collar locations were surveyed by qualified surveyors (Cubica Ingeniería Metrica S.L.) using standard differential global positioning system (DGPS) equipment achieving sub decimetre accuracy in horizontal and vertical position. Down-hole surveys were undertaken using a Geovista down-hole deviation probe. Measurements are taken every 1cm down hole and averaged every 10m. No strongly magnetic rocks are present within the deposit which may affect magnetic based readings. Berkeley uses two down-hole gamma probes to provide eU3O8 ("equivalent" U3O8 grade and e-grade) data. The probes were originally calibrated by the manufacturer (Geovista, UK) and are currently sent, on an annual basis, to Borehole Wireline Pty Ltd in South Australia for their recalibration in their test pits. Calibration includes the determination of k-factor, deadtime, bore hole diameter and fluid corrections, which are reported in the "Primary Probe Calibration" document. All parameters are then applied during the in-house e-grade calculation process. JEN sampled whole core using 0.25m, 0.50m and 1.00m interval lengths. QA/QC protocols used are unknown.
	Aspects of the determination of mineralisation that are Material to the Public Report. In cases where 'industry standard' work has been done this would be relatively simple (eg 'reverse circulation drilling was used to obtain 1 m samples from which 3 kg was pulverised to produce a 30 g charge for fire assay'). In other cases more explanation may be required, such as where there is coarse gold that has inherent sampling problems. Unusual commodities or mineralisation types (eg submarine nodules) may warrant disclosure of detailed information.	Berkeley RC drill samples are collected over 1m intervals and split on site using cone and quarter method (2008 and 2013 campaigns) or two riffle splitters in cascade (2014 campaign) to provide an approximate 3-5kg sample. Scintillometer measurements were taken on all Berkeley RC samples and this data was then used to select the samples to be sent to external laboratories for sample preparation and analysis. Indicative mineralised intervals were determined from this data and the sampling extended up and down hole by at least 2-5m. Samples were further split in the core shed using a riffle splitter such that 0.7-1kg samples were sent to ALS laboratories for preparation (Seville, Spain) and analysis (Loughrea, Ireland and Vancouver, Canada). Samples were dried, fine crushed down to 70% below 2mm, split to obtain 250g and pulverised with at least 85% of the sample passing 75µm. 10g of sample was used for uranium analysis by the pressed powder X-ray fluorescence (XRF) method (2013 and 2014 drilling campaigns). Samples from the 2007 and 2008 drilling campaigns were sent to Actlabs Canada for uranium analysis by the Delayed Neutron Counting (DNC) method.  JEN core samples were prepared in internal company laboratories and assayed for uranium using XRF, Atomic absorption spectroscopy (AAS) or fluorometric methods.
Drilling techniques	Drill type (eg core, reverse circulation, open-hole hammer, rotary air blast, auger, Bangka, sonic, etc) and details (eg core diameter, triple or standard tube, depth of diamond tails, face-sampling bit or other type, whether core is oriented and if so, by what method, etc).	Berkeley drilling comprised both DD (HQ) and RC drilling using a 140mm diameter face sampling hammer. For angled DD oriented core was achieved using DeviCore measurements (2014). The historical JEN drilling, which accounts for approximately 30% of the total drilling, was used DD (NQ).
Drill sample recovery	Method of recording and assessing core and chip sample recoveries and results assessed.	Berkeley and JEN DD typically recorded overall core recoveries in excess of 90%, which is considered acceptable. Berkeley RC drill samples are collected over 1m intervals through a cyclone. Plastic sample bags are strapped to the cyclone to maximise sample recovery. Individual sample bags were not weighed to assess sample recovery but a visual inspection was made by the Company geologist to ensure all samples are of approximately equivalent size.
	Measures taken to maximise sample recovery and ensure representative nature of the samples.	The DD drilling rigs used face discharge bits to ensure a low contact between the rock and drilling fluids, minimising ore washing. Core was cut using a water saw with care taken to ensure minimal ore loss. The RC drilling rigs utilised suitably sized compressors to ensure dry samples where possible. Plastic sample bags were strapped to the cyclone to maximise sample recovery. Sample logs record whether the sample was dry, moist or wet.
	Whether a relationship exists between sample recovery and grade and whether sample bias may have occurred due to preferential loss/gain of fine/coarse material.	Due to the solubility and mobility of the uranium minerals the use of water in core recovery in DD is controlled.   The core and RC sample recoveries are of an acceptable level and no bias is expected from any sample losses.
Logging	Whether core and chip samples have been geologically and geotechnically logged to a level of detail to support appropriate Mineral Resource estimation, mining studies and metallurgical studies.	Berkeley geological logging of DD core included recording descriptions of lithology, age, colour, oxidation, mineralisation, alteration, weathering, structures, textures, grain size and mineralogy. Berkeley geotechnical logging of DD core included recording descriptions of integrity (recovery and RQD), materials (lithology, rock strength and depth oxide staining), structures (type, angle, contact type, infill, weathering) Berkeley structural logging of DD core included recording descriptions of structure type, structural angles, contact type, infill, line type and slip direction. Berkeley alteration logging of DD core included recording descriptions of metamorphic textures, alteration mineralogy and mineralisation style. Berkeley geological logging of RC chip samples included recording descriptions of lithology, weathering, alteration and mineralisation. A scintillometer reading of counts per second (cps) was recorded for each 1m sample (quantitative). JEN geological logging of DD core included recording descriptions of lithology, iron oxides, sulphides, uranium mineralogy, fracturing and no recovery zones.
	Whether logging is qualitative or quantitative in nature. Core (or costean, channel, etc) photography.	Geological logging is qualitative in nature. Berkeley DD core boxes and samples and RC samples and chip trays were photographed. JEN did not take photographs of drill core.
	The total length and percentage of the relevant intersections logged.	All DD and RC drill holes were logged in full by geologists employed by the Companies.
Sub-sampling techniques and sample preparation	If core, whether cut or sawn and whether quarter, half or all core taken.	Berkeley DD core was sampled using 0.25-1.85m intervals in the mineralised zones, including areas of internal low grade or waste. In addition, the sampling was extended 3-5m up and down hole from the interpreted mineralised zone. Half or quarter core was used for sampling. JEN DD core was sampled using 0.25m, 0.50m and 1.00m intervals in the mineralised zones, with 0.25m intervals being the most frequent sample length. Whole core was used for sampling.
	If non-core, whether riffled, tube sampled, rotary split, etc. and whether sampled wet or dry.	Berkeley RC drill samples were collected at 1m intervals. RC intervals were sampled by splitting dry samples in the field to 3-5kg using cone and quarter method (2008 and 2013 campaigns) or two riffle splitters in cascade (2014 campaign) and further split in the core shed to 0.7-1kg using a riffle splitter. Where samples were wet they were dried prior to spitting. In rare cases, wet samples were split using a cone and quarter method.
	For all sample types, the nature, quality and appropriateness of the sample preparation technique.	Berkeley samples (2013 and 2014 drilling campaigns) were sent to ALS laboratories for preparation and analysis. Samples were dried, fine crushed down to 70% below 2mm, split to obtain 250g and pulverised with at least 85% of the sample passing 75µm. 10g of sample was used for uranium analysis by pressed powder XRF method. Samples from the 2007 and 2008 drilling campaigns were sent to Actlabs Canada for uranium analysis by the DNC method.  These methods are considered appropriate for this style of uranium mineralisation. JEN core samples were prepared and assayed for uranium at internal company laboratories using XRF, AAS or fluorometric methods.
	Quality control procedures adopted for all sub-sampling stages to maximise representivity of samples.	Previous Berkeley's field tests determined that the sample size and method of sampling produce representative RC samples. QA/QC procedures involved the use of standards and blanks which were inserted into sample batches at a frequency of approximately 15%. Quality control procedures used by JEN are unknown.
	Measures taken to ensure that the sampling is representative of the in situ material collected, including for instance results for field duplicate/second-half sampling.	Duplicate splits of RC samples were taken every 10m down hole within the sampled intervals by Berkeley. The results from these duplicates generally show acceptable repeatability, however indications of inhomogeneity were observed in a number of duplicates.
	Whether sample sizes are appropriate to the grain size of the material being sampled.	The uranium is typically very fine grained. Previous test work carried out by Berkeley using different sample sizes demonstrated that the selected sample size is appropriate.
Quality of assay data and laboratory tests	The nature, quality and appropriateness of the assaying and laboratory procedures used and whether the technique is considered partial or total.	Berkeley assayed samples for uranium using the DNC method during the 2007 and 2008 drilling campaigns and pressed powder XRF during the 2013 and 2014 drilling campaigns. These analytical methods report total uranium content. JEN assayed samples for uranium were completed at internal company laboratories using XRF, AAS or fluorometric methods. No QA/QC data is available for this historical data.
	For geophysical tools, spectrometers, handheld XRF instruments, etc, the parameters used in determining the analysis including instrument make and model, reading times, calibrations factors applied and their derivation, etc.	Down-hole gamma logging was undertaken for all probe accessible holes drilled by Berkeley to provide eU3O8 data. The down-hole gamma response was converted eU3O8 by correcting for radon, hole diameter, air/water and a deconvolution filter was also applied. eU3O8 data was only considered in the mineral resource estimation process when chemical assay data was not available.
	Nature of quality control procedures adopted (eg standards, blanks, duplicates, external laboratory checks) and whether acceptable levels of accuracy (ie lack of bias) and precision have been established.	Standards, blanks and duplicates were regularly inserted into the sample stream by Berkeley, with approximately 15-20% of all samples related to quality control. The external laboratories used also maintain their own process of QA/QC utilising standards, repeats and duplicates. Review of the Berkeley quality control samples, as well as the external laboratory quality QA/QC reports, has shown no sample preparation issues, acceptable levels of accuracy and precision and no bias in the analytical datasets. JEN used internal company laboratories. No QA/QC data is available for this historic data.
Verification of sampling and assaying	The verification of significant intersections by either independent or alternative company personnel.	Reported significant intersections were checked and verified by Senior Geological management.
	The use of twinned holes.	No twinned holes were drilled for the current mineral resource estimation process.
	Documentation of primary data, data entry procedures, data verification, data storage (physical and electronic) protocols.	All primary data was recorded in templates designed by Berkeley. Assay data from the external laboratory is received in spreadsheets and downloaded directly into an Access Database managed by the Company. Data is entered into controlled excel templates for validation. The validated data is then loaded into a password secured relational database by a designated Company geologist. Daily backups of all digital data are undertaken. These procedures are documented in the Berkeley Technical Procedures and Protocols manual. JEN primary paper data was digitalized and recoded following the Berkeley protocols. The validated data was then loaded into a password secured relational database by a designated Company geologist.
	Discuss any adjustment to assay data.	Uranium (ppm) assays received from the external laboratory were converted to U3O8 (ppm) using the stoichiometric factor of 1.179.
Location of data points	Accuracy and quality of surveys used to locate drill holes (collar and down-hole surveys), trenches, mine workings and other locations used in Mineral Resource estimation.	Berkeley drill hole collar locations were surveyed by qualified surveyors (Cubica Ingeniería Metrica S.L) using standard DGPS equipment achieving sub decimetre accuracy in horizontal and vertical position. Berkeley down-hole surveys were undertaken using a Geovista down-hole deviation probe. Measurements were taken every 1cm down hole and averaged every 10m. No strongly magnetic rocks are present within the deposit which may affect magnetic based readings. JEN holes were drilled on grid coordinates and were not surveyed after drilling.
	Specification of the grid system used.	The grid system is UTM ED1950 Zone 29N.
	Quality and adequacy of topographic control.	Topographic control was based on a digital terrain model with sub metric accuracy sourced from the Spanish Geographical Institute (Instituto Geográfico Nacional) and was verified through detailed drill hole collar surveys by a qualified surveyor using a DGPS.
Data spacing and distribution	Data spacing for reporting of Exploration Results.	The majority of the Berkeley drilling was undertaken on a notional 100m by 100m grid, with section lines orientated approximately perpendicular to the interpreted strike of the mineralisation. The historical JEN drilling was completed on a closer spaced 35m by 35m grid within the previous resource area.
	Whether the data spacing and distribution is sufficient to establish the degree of geological and grade continuity appropriate for the Mineral Resource and Ore Reserve estimation procedure(s) and classifications applied.	The data spacing (notionally 100m by 100m) is considered sufficient to imply but not verify geological and grade continuity, and allow the estimation of Inferred Mineral Resources.
	Whether sample compositing has been applied.	No compositing of RC samples in the field has been undertaken.
Orientation of data in relation to geological structure	Whether the orientation of sampling achieves unbiased sampling of possible structures and the extent to which this is known, considering the deposit type.	The mineralised zone is a 2-3km scale fold structure with the dominant strike direction being NNE-SSW. Despite the general dip of the host geological units and structures ranging from 50-80°, the mineralised zone is interpreted to be sub-horizontal (due to post mineralisation supergene processes) to shallowly dipping.
	If the relationship between the drilling orientation and the orientation of key mineralised structures is considered to have introduced a sampling bias, this should be assessed and reported if material.	The majority of DD and RC drill holes are vertical. Due to the interpreted flat lying nature of the mineralisation, no sampling bias is considered to have been introduced by the orientation of the drilling.
Sample security	The measures taken to ensure sample security.	Chain of custody is managed by Berkeley. Samples were transported from the drill site by Company vehicle to a sample preparation shed where samples were prepared for dispatch. Samples were sent directly from the sample preparation shed to the laboratory using a certified courier or a Berkeley owned vehicle authorised for radioactive materials transport. No other freight was transported with the samples which were taken directly from the Berkeley facility to the external laboratory. Sample submission forms were sent in paper form with the samples as well as electronically to the laboratory. Reconciliation of samples occurred prior to commencement of sample preparation for assaying. The historical drilling samples were prepared and analysis using internal company laboratories. The chain of custody is unknown.
Audits or reviews	The results of any audits or reviews of sampling techniques and data.	Sampling techniques and procedures, as well as QA/QC data, are reviewed internally an ongoing basis. Malcolm Titley (CP, Geology Consultant, Maja Mining Limited) has independently reviewed the sampling techniques, procedures and data. He has undertaken a number of site visits to review and inspect the application of procedures. These reviews have concluded that the sampling and analytical results have resulted in data suitable for incorporation into Mineral Resource estimation.

Section 2 Reporting of Exploration Results

(Criteria listed in the preceding section also apply to this section.)

Criteria	JORC Code explanation		Commentary
Mineral tenement and land tenure status		Type, reference name/number, location and ownership including agreements or material issues with third parties such as joint ventures, partnerships, overriding royalties, native title interests, historical sites, wilderness or national park and environmental settings.	The Zona 7 Prospect lies on the Alisos Investigation Permit PI 6605-20 which is 100% owned by Berkeley Minera España S.L, a wholly owned subsidiary of Berkeley Resources Limited. The Alisos Investigation Permit is currently in the first year of its second three year term and will expire on 4 January 2017. No historical sites or national parks are located within the Permit. The Zona 7 Prospect is located adjacent to the village of Villavieja de Yeltes.
		The security of the tenure held at the time of reporting along with any known impediments to obtaining a licence to operate in the area.	Tenure in the form of an Investigation Permit has been granted and is considered secure. There are no known impediments to obtaining a licence to operate in this area.
Exploration done by other parties		Acknowledgment and appraisal of exploration by other parties.	Previous exploration at Zona 7 was completed initially by Junta de Energía Nuclear (JEN) and then Empresa Nacional de Uranio S.A. (ENUSA), both Spanish state run companies, from the late 1950's through to the mid 1980's. Work completed by JEN and ENUSA included mapping, radiometric surveys, trenching and diamond and open-hole drilling. A detailed data assessment and verification of the historical data supplied by JEN and ENUSA has been undertaken by Berkeley. No significant issues with the data were detected.
Geology		Deposit type, geological setting and style of mineralisation.	The uranium mineralisation is hosted within Ordovician metasediments adjacent to granite. The mineralisation typically occurs as a sub-horizontal to shallowly dipping layer occurring between surface and 100m depth. The style of the uranium mineralisation includes veins, stockwork and disseminated mineralisation in joint/fracture filling associated with brittle deformation. Uraninite and coffinite are the primary uranium minerals. Secondary uranium mineralisation is developed in "supergene-like" tabular zones corresponding to the depth of weathering. Most of the mineralisation is hosted within partially weathered and unweathered metasediment. This deposit falls into the category defined by the International Atomic Energy Association (IAEA) as Vein Type, Sub Type Iberian Type.
Drill hole Information		A summary of all information material to the understanding of the exploration results including a tabulation of the following information for all Material drill holes: o easting and northing of the drill hole collar o elevation or RL (Reduced Level - elevation above sea level in metres) of the drill hole collar o dip and azimuth of the hole o down hole length and interception depth o hole length.	No new exploration results are included in this release.
		If the exclusion of this information is justified on the basis that the information is not Material and this exclusion does not detract from the understanding of the report, the Competent Person should clearly explain why this is the case.	All Berkeley drill holes within the resource area have previously been reported in releases to the ASX providing collar easting, northing, elevation, dip, azimuth and length of hole and mineralised intercepts as encountered.
Data aggregation methods		In reporting Exploration Results, weighting averaging techniques, maximum and/or minimum grade truncations (eg cutting of high grades) and cut-off grades are usually Material and should be stated.	No new exploration results are included in this release. All Berkeley drill holes within the resource area have previously been reported.
		Where aggregate intercepts incorporate short lengths of high grade results and longer lengths of low grade results, the procedure used for such aggregation should be stated and some typical examples of such aggregations should be shown in detail.	No new exploration results are included in this release. All Berkeley drill holes within the resource area have previously been reported.
		The assumptions used for any reporting of metal equivalent values should be clearly stated.	No metal equivalent values were used.
Relationship between mineralisation widths and intercept lengths		These relationships are particularly important in the reporting of Exploration Results. If the geometry of the mineralisation with respect to the drill hole angle is known, its nature should be reported.	All drilling was planned in such a way as to intersect expected mineralisation in a perpendicular manner. The uranium mineralisation is interpreted to be flat lying to shallowly dipping so all of the RC holes were drilled vertically. The previously reported (no new exploration results are included in this release) down-hole intervals were therefore interpreted to approximate true widths however, given the early stage nature of the work, confidence in the orientation of the mineralisation is low.
		If it is not known and only the down hole lengths are reported, there should be a clear statement to this effect (eg 'down hole length, true width not known').	The previously reported (no new exploration results are included in this release) down-hole intervals were interpreted to approximate true widths however, given the early stage nature of the work, confidence in the orientation of the mineralisation is low.
Diagrams		Appropriate maps and sections (with scales) and tabulations of intercepts should be included for any significant discovery being reported These should include, but not be limited to a plan view of drill hole collar locations and appropriate sectional views.	Appropriate diagrams, including a drill plan and cross sections, are included in the main body of the ASX version of this release.
Balanced reporting		Where comprehensive reporting of all Exploration Results is not practicable, representative reporting of both low and high grades and/or widths should be practiced to avoid misleading reporting of Exploration Results.	No new exploration results are included in this release. All Berkeley drill holes within the resource area have previously been reported.
Other substantive exploration data		Other exploration data, if meaningful and material, should be reported including (but not limited to): geological observations; geophysical survey results; geochemical survey results; bulk samples - size and method of treatment; metallurgical test results; bulk density, groundwater, geotechnical and rock characteristics; potential deleterious or contaminating substances.	Down-hole gamma logging of all Berkeley holes was undertaken to provide eU3O8 data. Prior comparisons of eU3O8 data with chemical assay data have shown that on average eU3O8 tends to underestimate at higher grades (>500ppm) and overestimate at lower grades (<200ppm). Accordingly, the eU3O8 data is not considered of sufficient quality to replace chemical assay data for the purposes of resource estimation. The Mineral Resources reported in this release are estimated using chemical assay data as the primary method for grade estimation in the resource modelling process and eU3O8 data is only used where there were no assay data available.
Further work		The nature and scale of planned further work (eg tests for lateral extensions or depth extensions or large-scale step-out drilling).	Further work planned for the Zona 7 Prospect includes infill drilling that would be focused on improving geological confidence and resource classification. The mineralisation remains open along the north-western margin and along strike, with both areas to be targeted in subsequent drilling campaigns Geological studies will include detailed interpretation of lithology, structure and weathering and an assessment of potential relationships between these factors and uranium grade distribution. Further work is also planned on a number of other exploration targets within the Retortillo Region.
		Diagrams clearly highlighting the areas of possible extensions, including the main geological interpretations and future drilling areas, provided this information is not commercially sensitive.	These are shown in the main body of the ASX version of this release.

Section 3 Estimation and Reporting of Mineral Resources

(Criteria listed in the preceding section also apply to this section.)

Criteria	JORC Code explanation	Commentary
Database integrity	Measures taken to ensure that data has not been corrupted by, for example, transcription or keying errors, between its initial collection and its use for Mineral Resource estimation purposes.	Drill hole data is stored in a password protected relational database (Access). Drill data recorded in a spreadsheet is transferred to the database by the project geologist who is responsible for reviewing and validating the data. Assay data is received from the external laboratories in digital format and is loaded directly into the database. Geological logging is restricted to appropriate codes relevant to the local geology, mineralisation, weathering and alteration setting. A copy of the master database is linked to Surpac mining software for Mineral Resource Estimation (MRE).
	Data validation procedures used.	Database validation checks including collar survey position, down hole survey control, assay limits, e-grade profiles, sample intervals and logging codes are completed prior to the data being transferred to the master database.
Site visits	Comment on any site visits undertaken by the Competent Person and the outcome of those visits.	Sampling techniques and procedures, as well as QA/QC data, are reviewed internally an ongoing basis. Malcolm Titley, (CP, Geology Consultant, Maja Mining Limited) has reviewed the sampling techniques, procedures, data and resource estimation methodology. He has undertaken a number of site visits, the latest being in September 2014, to review and inspect the application of these procedures. He concludes that the sampling and analytical results available are appropriate for estimation of the Mineral Resource.
	If no site visits have been undertaken indicate why this is the case.	Site visits have been undertaken.
Geological interpretation	Confidence in (or conversely, the uncertainty of) the geological interpretation of the mineral deposit.	The confidence of the geological interpretation is appropriate for the current level of resource estimation. The resource is defined within mineralised envelopes which encompass all zones of significant mineralisation.
	Nature of the data used and of any assumptions made.	Geology and mineralisation interpretation is based on geological logging and sample assays derived from RC and DD drilling, along with cross sectional interpretations which include surface mapping information and geophysical studies.
	The effect, if any, of alternative interpretations on Mineral Resource estimation.	Structural studies show dips of structures vary between 50° and 80° however; the uranium mineralisation has undergone supergene remobilisation and is interpreted to be flat lying to shallowly dipping and generally within 100m from surface.
	The use of geology in guiding and controlling Mineral Resource estimation.	On the deposit scale the uranium grade is controlled by both lithology and structure, while on a local scale the grade is interpreted to be influenced by supergene processes.
	The factors affecting continuity both of grade and geology.	Geological logging and uranium assay of samples from drill holes has demonstrated the continuity of the grade and lithology between mineralised sections. Breaks in continuity are likely due to structural offsets, some of which have been observed or interpreted from surface mapping.
Dimensions	The extent and variability of the Mineral Resource expressed as length (along strike or otherwise), plan width, and depth below surface to the upper and lower limits of the Mineral Resource.	The Zona 7 uranium mineralisation covers an area of approximately 3.0km by 0.4km and generally occurs within 100m of surface.
Estimation and modelling techniques	The nature and appropriateness of the estimation technique(s) applied and key assumptions, including treatment of extreme grade values, domaining, interpolation parameters and maximum distance of extrapolation from data points. If a computer assisted estimation method was chosen include a description of computer software and parameters used.	A mineralised envelope at Zona 7 is created encompassing all zones of significant mineralisation. A number of different domains have been interpreted. Geostatistical variogram modelling was used to determine appropriate parameters for estimation of uranium grade using Ordinary Kriging (OK). Surpac software was used for mineralisation volume interpretation and uranium grade estimation. Three sources of drillhole uranium grade data was used: ·     Chemical U3O8 (ppm): 62% ·     Radiometric Equivalent (ppm): 6% ·     Background based on XRF and Gamma probe results (10 ppm U3O8): 32% The drill hole spacing is nominally 100m by 100m, with some closer spacing at 50m by 50m or 35m by 35m. Five mineralisation domains were identified (D2, D3, D4, D5 and D6). 1m samples were used to estimate grade into 25m by 25m by 6m parent blocks. In order to reduce local bias due to extreme high grades, top cuts were applied: ·      D2: 1,800ppmU3O8 ·      D3: none ·      D4: 3,400ppmU3O8 ·      D5: 1,300ppmU3O8 ·      D6: 5,000ppmU3O8 Number of 1m samples required to make an estimate:  ·      Minimum samples = 6 ·      Maximum samples = 30 Search ellipse radii variable per domain in meters, along strike/ down-dip/across-strike: ·      D2: 40/60/120 ·      D3: 55/80/160 ·      D4: 55/80/160 ·      D5: 95/140/280 ·      D6: 95/140/280 Search orientation variable per domain (dip, plunge, dip dir): ·      D2: (130, 0, 0) ·      D3: (165, 0, 0) ·      D4: (50, 0, 0) ·      D5: (40, 0, 0) ·      D6: (25, 0, 0) Search radii used for OK were increased by a factor of 2-2-1 and 4-3-2 (major-semi-major-minor) to estimate a grade for blocks not estimated in the 1st or 2nd pass respectively. In-situ dry bulk densities were assigned based on zones of weathering intensity and used to estimate tonnage.
	The availability of check estimates, previous estimates and/or mine production records and whether the Mineral Resource estimate takes appropriate account of such data.	The current resource estimate was compared with the previous resource estimate (February 2010) which was based on earlier drill campaigns (historical, 2007 and 2008) and to a polygonal estimation. Both of which support the current results. No mining production has taken place at Zona 7.
	The assumptions made regarding recovery of by-products.	The resource model only estimates uranium.
	Estimation of deleterious elements or other non-grade variables of economic significance (eg sulphur for acid mine drainage characterisation).	At this stage, there are no deleterious elements or other non-grade variables identified as being of economic significance at Zona7.
	In the case of block model interpolation, the block size in relation to the average sample spacing and the search employed.	The uranium grade is estimated into the 25m (X) by 25m (Y) by 6m (Z) blocks. This compares to the average drill spacing of 50-100m in X and Y and an assumed mining bench height of 6m. This block size was chosen to match the potential open cut mining methodology.
	Any assumptions behind modelling of selective mining units.	Selective mining unit dimensions have not been considered in the current model.
	Any assumptions about correlation between variables.	Uranium is the only economic metals estimated in the current resource model.
	Description of how the geological interpretation was used to control the resource estimates.	Geological interpretation controlled the volume of the resource estimate by restricting the interpretation of the mineralisation volume and associated samples to material with continuity above a 100 ppm U3O8 grade. The domains are based on geology, structure and uranium grade with defined zones of mineralisation that show continuity along and across strike. A further division of the model into completely weathered, partially weathered and fresh rock is applied by triangulated surfaces interpreted from the logging of the drill samples. This division is only applied for density purposes.
	Discussion of basis for using or not using grade cutting or capping.	Uranium grade distribution exhibits a strong positive skewness, so a top cut was applied to reduce local bias by extreme grades outliers - nominally approximating the 97.5 population percentile. The domains were assessed independently and a top cut grade was determined for each domain.
	The process of validation, the checking process used, the comparison of model data to drill hole data, and use of reconciliation data if available.	Validation of the MRE included visual inspection of the grade distribution compared to the drill data, comparison of block model statistics to the sample statistics and generation of swath plots. These confirmed that the MRE appropriately represents the grade and tonnage distribution of the uranium mineralisation at the confidence levels reported.
Moisture	Whether the tonnages are estimated on a dry basis or with natural moisture, and the method of determination of the moisture content.	The resource tonnage is reported on a dry bulk density basis. In-situ dry bulk density measurements were completed on dry core and sample grades are reported using dry weight. No moisture content of drill core has been determined.
Cut-off parameters	The basis of the adopted cut-off grade(s) or quality parameters applied.	The MRE has been reported using a 200ppm U3O8 cut-off grade. Recent feasibility studies on adjacent properties have demonstrated that a 100ppm U3O8 cut-off is economic. Based on the current uranium market, reporting of the MRE at a 200 ppm cut-off grade is both justifiable and consistent with previous published MRE's for this style of mineralisation.
Mining factors or assumptions	Assumptions made regarding possible mining methods, minimum mining dimensions and internal (or, if applicable, external) mining dilution. It is always necessary as part of the process of determining reasonable prospects for eventual economic extraction to consider potential mining methods, but the assumptions made regarding mining methods and parameters when estimating Mineral Resources may not always be rigorous. Where this is the case, this should be reported with an explanation of the basis of the mining assumptions made.	The resource can potentially be extracted using open pit mining methods, with the recovery of uranium through the application of acid heap leach methods. Indicative parameters used for pit optimisation purposes in recent feasibility studies on adjacent properties are: Uranium selling price: US$65/lb U3O8, Total Mining Cost: US$7.5/lb U3O8 Mining recovery: 97.5% Mining dilution: 2.5% Plant Process Cost: US$7.4/lb U3O8 Recovery U3O8: 85% Royalties: 1.2%
Metallurgical factors or assumptions	The basis for assumptions or predictions regarding metallurgical amenability. It is always necessary as part of the process of determining reasonable prospects for eventual economic extraction to consider potential metallurgical methods, but the assumptions regarding metallurgical treatment processes and parameters made when reporting Mineral Resources may not always be rigorous. Where this is the case, this should be reported with an explanation of the basis of the metallurgical assumptions made.	No metallurgical testwork has been undertaken for Zona 7 however, numerous metallurgical testwork programs have been completed for deposits hosted in similar geological settings in close proximity to the Zona 7 deposit. The results of this testwork showed the mineralisation to be amenable to convention acid heap leach, with uranium recoveries in the order of 85%.
Environmental factors or assumptions	Assumptions made regarding possible waste and process residue disposal options. It is always necessary as part of the process of determining reasonable prospects for eventual economic extraction to consider the potential environmental impacts of the mining and processing operation. While at this stage the determination of potential environmental impacts, particularly for a greenfields project, may not always be well advanced, the status of early consideration of these potential environmental impacts should be reported. Where these aspects have not been considered this should be reported with an explanation of the environmental assumptions made.	It is planned that all spent heap leach (ripios) material will be returned to the open pit which will be lined so as to encapsulate the ripios. Any Naturally Occurring Radioactive Material (NORM) or Acid Rock Drainage (ARD) waste will also be stored within the lined pit. An Environmental Scoping Study will serve to define the scope and content of the Environmental and Social Impact Assessment.
Bulk density	Whether assumed or determined. If assumed, the basis for the assumptions. If determined, the method used, whether wet or dry, the frequency of the measurements, the nature, size and representativeness of the samples.	Bulk density values were derived from 304 solid‐fluid pycnometer measurements. These values have been validated with diamond core bulk density results obtained using the water immersion method. The in-situ dry bulk density values are: Completely weathered: 2.33 g/cm3 Partially weathered: 2.43 g/cm3 Fresh rock: 2.66 g/cm3
	The bulk density for bulk material must have been measured by methods that adequately account for void spaces (vugs, porosity, etc), moisture and differences between rock and alteration zones within the deposit.	Fresh and slightly weathered rock is competent enough to ensure the method used takes into account any rock porosity. A factor derived from comparison with DD core was used to adjust the weathered material.
	Discuss assumptions for bulk density estimates used in the evaluation process of the different materials.	The density measurements have been classified by weathering intensity, defined by the geological logging. Three dominant zones have been identified - completely weathered, partially weathered and fresh rock. The average of the density data from each zone was applied in the resource model.
Classification	The basis for the classification of the Mineral Resources into varying confidence categories.	The reported MRE has been classified as Inferred after consideration of the following: ·      Adequate geological evidence and drill hole sampling is available to imply geological and grade continuity. ·      Adequate in-situ dry bulk density data is available to estimate appropriate tonnage factors. ·      Adequate mining, metallurgy and processing knowledge to imply potential prospect for eventual economic extraction.
	Whether appropriate account has been taken of all relevant factors (ie relative confidence in tonnage/grade estimations, reliability of input data, confidence in continuity of geology and metal values, quality, quantity and distribution of the data).	The reported MRE has been classified with consideration of the quality and reliability of the raw data, the confidence of the geological interpretation, the number, spacing and orientations of intercepts through the mineralised zones and knowledge of grade continuity gained from observations and geostatistical analysis.
	Whether the result appropriately reflects the Competent Person's view of the deposit.	The reported MRE and its classification are consistent with the Competent Person's (CP) view of the deposit. The CP was responsible for determining the resource classification.
Audits or reviews	The results of any audits or reviews of Mineral Resource estimates.	Berkeley has undertaken a review of the previous MRE and concluded that the estimate was developed using industry standard methods and that the estimate was considered to reflect the understanding of the geology and grade continuity. Malcolm Titley (CP, Geology Consultant, Maja Mining Limited) reviewed the reported MRE and concluded that the estimate appropriately represents the grade and tonnage distribution of uranium mineralisation at confidence levels commensurate with the Inferred resource classification.
Discussion of relative accuracy/ confidence	Where appropriate a statement of the relative accuracy and confidence level in the Mineral Resource estimate using an approach or procedure deemed appropriate by the Competent Person. For example, the application of statistical or geostatistical procedures to quantify the relative accuracy of the resource within stated confidence limits, or, if such an approach is not deemed appropriate, a qualitative discussion of the factors that could affect the relative accuracy and confidence of the estimate.	The confidence level is reflected in the resource classification category chosen for the reported MRE. The definition of Inferred Mineral Resources is appropriate for the level of study and the geological confidence imparted by the drilling grid. The reported MRE is considered appropriate and representative of the grade and tonnage at the 200ppm U3O8 cut-off grade. The application of geostatistical methods has helped to increase the confidence of the model and quantify the relative accuracy of the resource on a global scale. It relies on historical data being of similar standard as recent infill drilling. The relevant tonnages and grade are variable on a local scale. The nature of the mineralisation and the relatively high nugget effect may result in local grade estimates being lower confidence, with significant smoothing of the grade tonnage distribution at cut-off grades above 200ppm U3O8. A review of the grade estimation methodology is recommended before analysing the any potential resource at cut-off grades above 200ppm U3O8. The CP considers that the current drilling grid is insufficient for classification of the Mineral Resource as Indicated or Measured.
	The statement should specify whether it relates to global or local estimates, and, if local, state the relevant tonnages, which should be relevant to technical and economic evaluation. Documentation should include assumptions made and the procedures used.	The Zona 7 deposit is likely to have local variability. The global assessment is an indication of the average tonnages and grade estimate for each geological domain.
	These statements of relative accuracy and confidence of the estimate should be compared with production data, where available.	No production has been carried out at Zona 7.
