Sampling Techniques and Data Sample Clauses

Sampling Techniques and Data. Criteria JORC Code explanation Commentary Sub-sampling techniques and sample preparation > If core, whether cut or sawn and whether quarter, half or all core taken. > If non-core, whether riffled, tube sampled, rotary split, etc. and whether sampled wet or dry. > For all sample types, the nature, quality and appropriateness of the sample preparation technique. > Quality control procedures adopted for all sub- sampling stages to maximise representivity of samples. > Measures taken to ensure that the sampling is representative of the insitu material collected, including for instance results for field duplicate/second-half sampling. > Whether sample sizes are appropriate to the grain size of the material being sampled. This information release does not report drill sampling or results. This information release does not report drill sampling or results. The samples from the in-situ outcrops were collected as and comprised of rock-chips. The bagged samples were sent to ALS Chemex Lubumbashi (DRC) where they were crushed and pulverized to a pulp. A 250g subset was split from the pulp and sent to ALS Chemex Modderfontein (RSA) for analytical determinations No duplicate sampling has been undertaken for the rock chip or channel program. In- house laboratory duplicates have been relied upon. For first-pass reconnaissance sampling this is adequate. Sampling of pegmatites is problematic because of the variation in coarse grain size and minerals distribution. Of all the field surface sampling methods, channel sampling is considered to give the most reliable indication of the mineralization present as the resultant sample may incorporate a broader range of pegmatite material. The 2kg-3kg mass of the samples is appropriate to the sampling methodology and the material being sampled. Quality of assay data and laboratory tests > The nature, quality and appropriateness of the assaying and laboratory procedures used and whether the technique is considered partial or total. > For geophysical tools, spectrometers, handheld XRF instruments, etc., the parameters used in determining the analysis including instrument make and model, reading times, calibrations factors applied and their derivation, etc. > Nature of quality control procedures adopted (e.g. standards, blanks, duplicates, external laboratory checks) and whether acceptable levels of accuracy (i.e. lack of bias) and precision have been established. All samples from the sampling program were shipped to the ALS laboratory ...
