Quality of assay data
and laboratory tests
•
Whether logging is qualitative or quantitative in nature. Core (or
costean, channel, etc) photography.
The total length and percentage of the relevant intersections logged.
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 in
situ 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.
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 (eg standards, blanks,
duplicates, external laboratory checks) and whether acceptable levels
of accuracy (ie lack of bias) and precision have been established.
