Gold

Mineral Insights detects gold and minerals from a single measurement on unpolished drill core.

The above image shows the Mineral Insights detection at micron dimensions of gold (magenta) and the following sulphide minerals: chalcopyrite (green), pyrite (pink), molybdenite (orange) and sphalerite (blue). This measurement was done on unpolished drill core cut by a diamond saw and required only 90 seconds.

The information provided by this Mineral Insights measurement can be used to accelerate gold and mineral exploration, and to increase gold and mineral recovery and profitability for operations at a mine.


Mineral Insights versus Assay Grade

A comparison of Mineral Insights gold concentrations to assay gold grades from 0.5 ppm to 50 ppm which correlate well. The Mineral Insights grades are an average of 30 Mineral Insight measurement areas.

Gold in Quartz

Mineral Insights detects the surface features of a gold particle in quartz measuring 74 microns x 81 microns with micron resolution of detail (gold shown as magenta). Each pixel is 1.6 microns x 1.6 microns.

The mineral sample below was cut by a diamond saw and is unpolished.
