Drillholes prefixed with RUD were drilled by Greenwater during2000-2001. Drillholes prefixed with MXD were drilled by the MetalsEx sinceNovember 2005. 2. Collar Coordinates are the coordinates of the collar of thedrillholes. The drillholes are inclined -60degrees from horizontal, exceptingMXD3 (-70degrees), and orientated towards a grid azimuth of 100degrees(easterly). In general the drillholes are spaced 100 metres apart. 3. Au_eq 'gold equivalent grade' represents an arithmetic calculation ofthe value in US$ of the contained metal per tonne using the current metal prices(as at 27 March 2006) of US$560/oz gold and US$23.5/lb molybdenum. Metal pricessourced from the following websites: www.kitco.com and www.adanacmoly.com. 4. Given the limited nature of exploration activities to date, noassurance or implication is being given, or should be assumed to be being given,by the inclusion of these values in this report that the Runruno Project hasbeen, or will in the future be, deemed to be economic. 5. Reporting of the above composited intercepts was determined byapplying an upper and lower boundary defined by a low grade cut-off of 0.7g/tAu. Some composited intercepts include single metre, internal intercept gradesof less than 0.7g/t Au. Isolated single metre intercepts are not reported unlessconsidered to be significant. No high grade cut-off has been applied to theindividual gold or molybdenum assays. The results appear to show a variation in the gold:molybdenum ratio within thearea being drilled. The molybdenum grades appear to be increasing with depth. So far the results have been obtained from drilling on a 100m x 100-200m gridspacing over a surface area of approximately 1000 metres x 700 metres. Themineralised zones still appears to be approximately 100 metres thick with highergrade zones at the hangingwall and footwall positions within the zone. This areaencompasses the southern-most portion of the area previously drilled by Fil-Amduring the 1970s, upon which their resource calculation was based. The Company is currently about to extend the drilling area uphill to the eastand to the north RUNRUNO - SAMPLING & ANALYSIS Sample Preparation The drill core is taken from the drill site to a secure compound at theCompany's field camp and is logged by the geologist. The drill core is thensplit into two equal halves along its long axis, with one half being sampled atpredetermined intervals, bagged and sent for analysis. The remaining half-coreis retained in core boxes and stored on site for future reference. The bagged half-core samples are being submitted to an independent 'ISO17025accredited' laboratory for sample preparation and analyses for gold andmolybdenum. All of the half-core samples are crushed by the laboratory and a900-1000 gram split is taken, pulverized and presented for analysis. The remaining crushed sample is retained in bags and stored at the laboratoryfor a period of three months before being returned to the Company for storage.These remaining crushed samples will be used in the future for additionalanalyses for gold, molybdenum, silver, sulphur and other elements as deemednecessary, for example, for resource estimation work. Analytical Techniques Gold: Gold analysis is by classical 'Screen Fire Assay'technique that involves sieving a 900-1000 gram sample to 200 mesh (75microns).The entire oversize and duplicate undersize fractions are fire assayed and theweighted average gold grade calculated. This is one of the most appropriatemethods for determining gold content if there is a 'coarse gold' component tothe mineralisation. Molybdenum: The sample is dissolved in Aqua Regia (3:1 HCl:HNO3) andMolybdenum analysis is carried out by Inductively Coupled Plasma - OpticalEmission Spectrometry (ICP-OES) method.
