No documentation is available regarding the sampling of RC drillholes. It is assumed that procedures adopted were to industry standard at the time of drilling. The sampling techniques are considered to be appropriate such that the samples could be used to support the Mineral Resource estimate. Field duplicates were not utilised for the RC drilling. Sample sizes are considered appropriate to the grain size of the material being sampled. The Competent Person considers the sampling preparation techniques and sample sizes are considered appropriate to the grain size of the material being sampled. Quality of assay data and laboratory tests Diamond drill core and RC chip samples were submitted to Genalysis Laboratory Services in Perth, Western Australia. Each sample was analysed for gold, silver, copper, lead, zinc, barium, arsenic, bismuth, antimony, nickel, cobalt, iron and magnesium. Ore grade samples were subjected to a modified four-acid (HF, HNO3, HClO3, HCl) digest followed by optical emission spectroscopy (OES) analysis for all elements excluding gold. Gold was analysed by Fire Assay with atomic absorption spectroscopy finish (AAS) using a 50 g charge. This technique is considered total. Samples without visible mineralisation were treated by a normal four-acid (HF, HNO3, HClO3, HCl) digest followed by OES analysis for all elements excluding gold. These samples were analysed for gold by aqua regia digest of a 50 g charge followed by solvent extraction and flame AAS (Code B5/SAAS). Quality control (QC) procedures utilised included certified reference materials (CRMs, or “standards”) and blanks. Field duplicates were not taken during the sampling programs. The standards have performed well over time, providing a good indication of laboratory precision and accuracy during the analyses of the Sandiego samples. The Competent Person considers the analytical techniques used and the QC protocols and results to be appropriate for the style of mineralisation and support the reporting of the Mineral Resource. Verification of sampling and assaying Significant intercepts were verified by independent geologists from CSA Global during the 2006 drilling and relogging program, and by senior Anglo Australian Resources NL (AAR) geological personnel. Twin drilling was not used. CSA Global managed the drillhole database during the 2006 drilling and relogging program and imported all assays into a secure relational database. CSA Global procedures were followed regarding data entry and storage. No adjustments were made to assay data. The Competent Person considers the data verification work carried out was sufficient to support the reporting of the Mineral Resource. Location of data points Drillhole collars were surveyed by licensed surveyors using a differential global positioning system (GPS). Historical holes were surveyed in Australian Map Grid (AMG) and these collars were later translated to GDA. All holes were translated to a local mine grid using a two-point transformation. A topographic digital terrain model (DTM) was constructed using contour data derived from aerial photography flown in November 2007, with a horizontal spatial accuracy of 4 cm and vertical accuracy of 3 cm. The DTM is considered of adequate quality to support the Mineral Resource estimate. The Competent Person considers the data survey work carried out was sufficient to support the reporting of the Mineral Resource. Data spacing and distribution Drillholes are mostly orientated along an east-west line, with holes spaced between 25 m and 50 m along strike (north-south) and spaced 25 m along the drill line. Drillhole spacing is considered sufficient to establish the degree of geological and grade continuity appropriate for the Mineral Resource estimation procedures and classifications applied. Drillholes were not composited prior to geological modelling or Mineral Resource estimation. 6. Independent Technical Report continued 130
