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.

• Sampling method include half-core sampling of NQ2 core Diamond drilling

(DD).

• RC samples are collected by a cone splitter for single metre samples or a sampling spear for first pass composite samples using a face sampling hammer with a nominal 140mm hole.

Sampling

• Sampling is guided by Sandfire protocols as per industry standard.

Sampling

• 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.

• DD Sample size reduction is through a Jaques jaw crusher to -10mm with a second stage reduction via Boyd crusher to -4mm. Representative subsamples are split and pulverised through LM5.

• RC sample are crushed to -4mm through a Boyd crusher and representative subsamples pulverised via LM5.

• Pulverising is to nominal 90% passing -75µm and checked using wet sieving technique.

• Samples are assayed using Mixed 4 Acid Digest (MAD) 0.3g charge and

MAD Hotbox 0.15g charge methods with ICPOES or ICPMS.

The MAD Hotbox method is an extended digest method that approaches a total digest for many elements however some refractory minerals are not completely attacked. The elements S, Cu, Zn, Co, Fe, Ca, Mg, Mn, Ni, Cr, Ti, K, Na, V are determined by ICPOES, and Ag, Pb, As, Sb, Bi, Cd, Se, Te, Mo, Re, Zr, Ba, Sn, W are determined by ICPMS. Samples are analysed for Au, Pd and Pt by firing a 40g of sample with ICP AES/MS finish. Lower sample weights are employed where samples have very high S contents. This is a classical FA process and results in total separation of Au, Pt and Pd in the samples.

• The analytical methods are considered appropriate for this mineralisation styles.

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.

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.

• Refer to Appendix 1 of this accompanying document.

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.

• Significant intersections are based on greater than 0.5% Cu and may include up to a maximum of 3.0m of internal dilution, with a minimum composite grade of 1.0% Cu.

• Cu grades used for calculating significant intersections are uncut.

Data

aggregation methods

• 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.

• Minimum and maximum DD sample intervals used for intersection calculation are 0.3m and 1.2m respectively subject to location of geological boundaries.

• RC reported intersections are based on a regular 1m sample intervals.

Data

aggregation methods

• The assumptions used for any reporting of metal equivalent values should be clearly stated.

• No metal equivalents are used in the intersection calculation.

• Where core loss occurs; the average length-weighted grade of the two adjacent samples are attributed to the interval for the purpose of calculating the intersection. The maximum interval of missing core which can be incorporated with the reported intersection is 1m.

Relationship

between mineralisation

widths and intercept lengths

• These relationships are particularly important in the reporting of Exploration Results.

• Downhole intercepts of mineralisation reported in this release are from a drillhole orientated perpendicular to a modelled EM plate. The drillhole may not necessarily be perpendicular to the mineralised zone. All widths reported are downhole intervals.

Relationship

between mineralisation

widths and intercept lengths

• If the geometry of the mineralisation with respect to the drill- hole angle is known, its nature should be reported.

• The geometry of the mineralisation, relative to the drillhole, is unknown at this stage.

• 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').

• All intersections reported in this release are downhole intervals. True widths are not known.

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 maps are included within the body of the accompanying document.

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.

• The accompanying document is considered to represent a balanced report.
