EMED Mining - Biely VrchNovember 2010Diamond Drilling MethodologyMost drill holes were HQ diameter although some holes in difficult ground conditions were drilled atPQ diameter. Due to the differences in core diameters, quarter-core was sampled for the PQ diameterholes, which represented a similar volume to the half core from the smaller diameter NQ and HQholes.The drilling tested an area about 700 m north-south and 900 m east-west, closing off the mineralresource in both directions. Drill holes were spaced 50 m to 100 m apart along east-west orientatedgrid lines. All the drill holes were inclined either to the east or west in order to best define the extentof the mineralisation (figure 11).Drill-hole SurveysDrill-hole collar positions were surveyed to the nearest centimetre using total station methods. Thedrilling contractor performed down-hole surveys every 50 m and these survey readings were validatedby EMED and any discrepancies in consecutive readings were checked and corrected if necessary.The frequency of down-hole surveys was suitable given the minimal drill-hole deviation for thisdeposit.Core RecoveryDrill-hole core recoveries ranged from 0% to 100% of the individual drill-core intervals. The averagecore recovery was 90%. These results are acceptable, considering the soft and highly weatherednature of the rocks.The drilling pattern needs to be closed up to at least 50 m x 50 m x 50 m spacing in order to raise thecurrent Inferred mineral resource category to the Indicated and/or Measured mineral resourcecategory.13.0 SAMPLING METHOD AND APPROACHDrill core recovery intervals were recorded on the drillers log sheets and the drill core intervals,measured to an accuracy of 0.1m, were clearly marked by drill-run “depth” tags placed in the corebox. The core was securely boxed and labelled at the drill site and then transported to the projectoffice for geological logging by EMED’s geologists.The core was measured, and core recoveries logged by the EMED geologist. Samples were markedup at regular 1 m intervals without regard to lithology or mineralisation.Behre Dolbear considers that EMED’s sampling procedures are suitable for a bulk disseminated golddeposit such as Biely Vrch and conform to modern mining industry standards.14.0 SAMPLE PREPARATION, ANALYSES AND SECURITYThe NQ and HQ diameter core was sawn in half longitudinally and the PQ diameter core intoquarters, and for each 1m sample interval the half (or quarter) core was bagged and labelled ready tobe sent for assay.All the drill-hole survey data, drill-hole logging data and sample assay data was subsequently enteredinto a computerised database.<strong>NI</strong> <strong>43</strong>–<strong>101</strong> <strong>Technical</strong> <strong>Report</strong> 23 BEHRE DOLBEARLegal*5650400.1
EMED Mining - Biely VrchNovember 2010Samples were sent for analysis by fire-assay to the ALS Chemex laboratory at Rosia Montana,Romania. ALS Chemex laboratories are registered or are pending registration to ISO 9001:2000, andtheir analytical facilities have received ISO 17025 accreditations for specific laboratory procedures.One in twenty of the samples submitted to ALS for analysis were “standards” obtained fromGEOSTAT as pulps. In total, 20 different “standards” were used ranging from 0.003 g/t Au up to7.36 g/t Au. Local dolomite rock was also used as the reference material for “blanks”. The assayvalue for the “blank” was < 0.01 g/t Au. All bar one of the blank samples returned the expected assayvalue and it is concluded that no contamination of samples occurred during the sample preparationprocess.In total, 795 blanks and standards were sent to ALS for assaying during submission of routine drillsamples. Most returned assay results within 5% of the certified values. The results are summarised inFigure 12 below.Behre Dolbear concludes that a high level of confidence can be placed on the ALS-Chemex assayresults for the drilling at Biely Vrch.Figure 12Assays of 795 Blanks and Standards Compared to the Certified Values(at ALS Laboratory)Behre Dolbear considers that EMED’s sample preparation and sample analysis procedures aresuitable for a bulk disseminated gold deposit such as Biely Vrch and conform to modern miningindustry standards.<strong>NI</strong> <strong>43</strong>–<strong>101</strong> <strong>Technical</strong> <strong>Report</strong> 24 BEHRE DOLBEARLegal*5650400.1
