Pathfinder Exploration Pty Ltd can conduct
a variety of geochemical sampling and orientation surveys
MAGLAG sampling using Pathfinder Exploration's
MAGSAM 2000® rare earth magnetic sampler. MAGLAG samples
represent a proven method for trace element concentration
in the regolith, and can be analysed for a multi-element suite
using various partial digestion techniques. A recently developed
proprietary micro-cyanide leach (MCL) can be used to analyse
for gold and PGE at parts per trillion (ppt) levels.
- -5 mm soil, LAG & MMI coarse
soil & LAG samples.
- -75µm very fine fraction Ao soil
Stream Sediment Geochemistry
- -2mm BCL 2 kg (BLEG) & mini-BLEG(50
- Fine fraction (-75µm) overbank
stream sediment samples.
- MAGSTREAM stream sediment samples using
Pathfinder Exploration's MAGSAM 2000® rare earth magnetic
- Auger calcrete & ferricrete sampling
using the Predator auger drill and acid testing for pedogenic
- Salt lake sampling using the multi-purpose
Predator light weight auger drill towed behind a 4WD quad
bike. The method can be used to sample the reduced mud horizon
and be used for hydrogeochemistry of saline waters in the
salt lake. The reduced mud horizon (below the salt cap)
can be analysed using the innovative Enzyme Leach® digest
to reveal distinctive electrochemical "Rabbit Ears"
anomalies associated with reduced bodies that can include
mineralisation at depth.
Data Analysis & Statistical Techniques
- Simple frequency statistics, box and
whisker plots and correlation co-efficients can be used
to compare geochemical data.
- Multivariate statistics including factor
analysis and cluster analysis can reveal multi-element trends
associated with mineralisation or alteration.
- Pathfinder can undertake image processing
of raw data and statistical indices and provide full interpretation,
quality control, plotting and GIS services.
Case histories using the various geochemical
techniques are described in the attached Geochemical
Case Histories PDF file.
Details on the Predator auger drilling
rig are outlined in the Pathfinder
Exploration Manual PDF file.
