ANALYSIS AND SORTING
axis. Thus, the scanning motion along the core
axis results in an analysis of an area of 2 cm
width across the core top surface.
The most common scanning rate is 1 cm/s, but
this can be set freely. Raw data are collected
continuously and saved with a certain resolution
(eg centimetres), precisely referenced in three
dimensions to the point cloud data. By tagging
depth markers, such as core blocks or metre
marks, these references can be converted to
accurate downhole depths.
Final spectra are integrated from the raw data
on a desired running interval (eg decimetres or
metres) or according to a specified list of
intervals in table format. These spectra contain
the data used for spectral processing. Elemental
concentrations are calculated using fundamental
parameters (similar to
“mining mode” in field-
portable XRF units).
In summary the
Minalyzer offers high
resolution images; 3D
models of core and
tray; RQD; whole rock
geochemistry at any
resolution from cm up
to metres (the scanning
is continuous not spots
as other solutions); and
specific gravity. The
Minalyze dataset and software also enables
digital structural logging.
Currently Minalyze has instruments at the core
reference library in Adelaide; Glencore’s George
Fisher mine in Mount Isa; CSIRO’s research centre
in Perth (the Australian Resource Research Centre
- ARRC); and the Minalyzer core competence
centre in Perth. At PDAC 2018, Minalyze will also
release the world’s first cloud based solution for
3D core viewing in collaboration with the
Geological Survey of South Australia.

Elemental Analysis
Hitachi High-Tech Analytical Science has added
the X-MET8000 Expert Geo to its successful
range of X-MET8000 handheld XRF (X-ray
fluorescence) analysers for geochemical analysis
throughout the mining process, from the early
stages of exploration to process waste analyses.
The X-MET8000 Expert Geo offers fast material
screening, dramatically reducing the need for
laboratory analyses and their associated cost.
Easy to use and designed to withstand the
harshest environments and weather conditions,
the X-MET8000 Expert Geo offers results in
seconds with real time data sharing for fast
decision making. X-MET8000 Expert Geo can
measure up to 40 elements, with additional
elements available on request, and enables the
quantification of rare earth elements on a wide
range of samples including: rocks, cores, cuttings
and powders.
The X-MET8000’s speed allows high volumes
of analyses and the fast completion of testing
programmes, saving time and money. The
combination of the large area s
