In collaboration with Portable Spectral Services, four companies have utilised μ-XRF technology to gain valuable information from Nickel sulphide samples. Preliminary data on these samples have been released as part of their ASX announcements in the last month to support findings from their respective deposits.
Half core samples were analysed with the μ-XRF without any further sample preparation, producing elemental maps of the sample surfaces (Live NiS scan video: https://www.youtube.com/watch?v=HULM15oFc6g ). These maps have provided insight into element and mineral associations, micro textures, element liberation, and mineral genesis, in an effective way for conveying the concentration of economical elements in these announcements (Fig. 1).
A single dataset collected by the μ-XRF in a non-destructive manner produces both chemical information at a micro scale in spatial context, and mapped mineralogy inferred from the XRF data. This provides detailed knowledge of a sample to develop an advanced understanding of a deposit.
