All results reported are from Reverse Circulation (RC) drill samples collected over one metre (1m) intervals. Multiple methods were used to determine uranium mineralisation intervals including down hole gamma analysis, hand held scintillometer measurements and portable XRF analysis. Intervals containing uranium mineralisation were selected and submitted for laboratory assay analysis.

Standards and blanks are inserted 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 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.

Drill hole collar locations are surveyed by qualified surveyors (Cubica Ingeniería Metrica S.L) using standard differential GPS (DGPS) equipment achieving sub decimetre accuracy in horizontal and vertical position. Down-hole surveys are 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.

RC drill samples are collected over 1m intervals, manually homogenised before being split on site using a three tier riffle splitter to provide an approximate 3-5kg sample. In rare cases, wet samples are split using a cone and quarter method.

Scintillometer measurements are taken on all samples and this data is used to select the samples to be sent to external laboratories for sample preparation and analysis. Indicative mineralised intervals are determined from this data and the sampling extended up and down hole by at least 2-5m.

Samples are further split in the core shed using a scoop such that 0.7-1kg samples are sent to the preparation laboratories of ALS and AGQ (Seville, Spain) and analytical laboratory of ALS (Loughrea, Ireland). Samples are 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 is used for uranium analysis by pressed powder X-ray fluorescence (XRF) method.

Drilling was by the RC method drilling using a 140mm diameter face sampling hammer.

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 are not weighed to assess sample recovery but a visual inspection is made by the Company geologist to ensure all samples are of approximately equivalent size.

The RC drilling rigs utilised suitably sized compressors to ensure dry samples where possible. Plastic sample bags are strapped to the cyclone to maximise sample recovery. Sample logs record whether the sample is dry, moist or wet.

There is no known relationship between sample recovery and grade. The RC sample recoveries are of an acceptable level and no bias is expected from any sample losses.

Geological logging of RC chip samples includes recording descriptions of lithology, weathering, alteration and mineralisation. A scintillometer reading of counts per second (cps) is recorded for each 1m sample (quantitative).

Geological logging is qualitative in nature. RC samples and chip trays are photographed.

All RC drill holes are logged in full by Company geologists.

Not Applicable - RC drilling only.

RC drill samples are collected at 1m intervals. RC intervals are sampled by splitting dry samples in the field to 3-5kg using a three tier riffle splitter and further split in the core shed to 0.7-1kg using a scoop. Where samples are wet they are dried prior to spitting. In rare cases, wet samples are split using a cone and quarter method.

Samples are sent to ALS and AGQ laboratories for preparation. Samples are dried, fine crushed down to 70% below 2mm and pulverised with at least 85% of the sample passing 75µm. 10g of sample is used for uranium analysis by pressed powder XRF method. This is considered appropriate for this style of uranium mineralisation.

Previous field tests have determined that the sample size and method of sampling produce representative RC samples. QA/QC procedures involve the use of standards, duplicates and blanks which are inserted into sample batches at a frequency of approximately 15-20%.

Duplicate splits of RC samples are taken every 10m down hole within the sampled intervals. The results from these duplicates generally show acceptable repeatability.

The uranium is typically very fine grained. Previous test work carried out by Berkeley using different sample sizes has demonstrated that the selected sample size is appropriate.

Uranium analysis by pressed powder XRF method. This analytical method reports total uranium content.

Down-hole gamma logging is undertaken for all probe accessible drill holes to provide eU₃O₈ ("equivalent" U₃O₈ grade) data however, it is not currently considered of sufficient quality to replace chemical assay data for the purposes of reporting drilling results at Zona 7. The drill intersections reported in this release are calculated using only chemical assay data.

Standards, blanks and duplicates are regularly inserted into the sample stream 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, pulp repeats, sample duplicates and blanks.

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.

Reported significant intersections have been checked and verified by Senior Geological management.

No twinned holes were drilled in the current RC drilling program.

All primary data is 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.

Uranium (ppm) assays received from the external laboratory are converted to U₃O₈ (ppm) using the stoichiometric factor of 1.179.

Down-hole surveys are 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.

The grid system is ETRS 1989 UTM Zone 29N.

Topographic control is based on a digital terrain model with sub metric accuracy sourced from the Spanish Geographical Institute (Instituto Geográfico Nacional) and is verified through detailed drill hole collar surveys by a qualified surveyor using a DGPS.

This RC drilling program has been designed to cross significant mineralisation in deep depths.

The data spacing is not considered sufficient to assume geological and grade continuity, and will not allow the estimation of Mineral Resources on deep.

No compositing of RC samples in the field has been undertaken.

Shallow parts of the deposit show that the mineralised zone strikes northeast-southwest and is interpreted to be sub-horizontal (due to post mineralisation supergene processes) to shallowly dipping.

All of the RC drill holes reported in this release 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.

Chain of custody is managed by Berkeley. Samples are transported from the drill site by Company vehicle to a sample preparation shed where samples are prepared for dispatch. Samples are 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 is transported with the samples which are taken directly from the Berkeley facility to the external laboratory. Sample submission forms are sent in paper form with the samples as well as electronically to the laboratory. Reconciliation of samples occurs prior to commencement of sample preparation for assaying.

Sampling techniques and procedures, as well as QA/QC data, are reviewed internally an ongoing basis. Mr Malcolm Titley (Geology Consultant, Maja Mining Limited) has independently reviewed the sampling techniques, procedures and data. He has undertaken a site visit 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.
