Innovative and efficient
near surface analysis of
ultra fine regolith

LabWest has developed the UltraFine+™ analysis process in conjunction with CSIRO since 2017.

Analysis of the reactive 2-micron clay fraction, with microwave digestion and using the latest low detection level ICPMS technology, has proven to be useful for geologists and geochemists to help see through shallow to moderate cover.

UltraFine+™ is now an established approach to surface exploration analysis using proven geochemical methods to identify sensitive signals at surface.

A range of clients across Australia and the world are now using this innovative and efficient surface analysis, taking advantage of sensitive detection for gold, base metals, rare-earth and lithium exploration.

Find out more in this introductory video or see below for analysis options available in our UltraFine+™ packages, plus research reports and case studies.

An introduction to UltraFine+™

Effective and efficient exploration analysis

Increased Signal
to Background Ratio
Smaller Sample

A CSIRO/MRIWA project sponsored by LabWest

The significant potential of the UltraFine+™ approach to gold and base metals exploration in Australia was successfully demonstrated in a combined CSIRO/MRIWA project.

CSIRO/MRIWA Project M462 “Multi-scaled near surface exploration using ultrafine soils”, led by Dr. Ryan Noble, was completed in September 2018, with LabWest as a project participant and its commercial partner.

The technique delivers multielement analysis, mineralogy and several related parameters derived from the ultrafine (< 2 μm) fraction of soil samples. Concentration of gold and related metals in the ultrafine fraction gives stronger signals, generally well above instrumental detection limits, and increased signal-to-background ratios. Excellent reproducibility means smaller samples can be collected, leading to reduced sampling and transport costs, and lending itself to extracting significant additional value from historical sample libraries.

LabWest is now pleased to offer UltraFine+™ and related techniques to the wider minerals exploration community. A selection of UltraFine+™ packages is available in addition to our suite of Regolith Geochemical Analysis services.
