How It Works


Gold Sniffer With Case.png

The Gold Sniffer

The Gold Sniffer is a visible optics device that detects metals and minerals with a single measurement on samples such as drill core, crushed rock, pulps, sands, RAB or RC chips among other sample types.

Gold, Copper, Molybdenum & Minerals

The Gold Sniffer reveals valuable information about metal and minerals relationships with their host minerals that can accelerate exploration and increase recovery. The Gold Sniffer can detect gold, copper, molybdenum and other minerals. A Gold Sniffer measurement takes just 90 seconds and can be completed on many types of samples.

Easily Portable for On-site Results

The Gold Sniffer is portable and battery operated. The entire Gold Sniffer unit fits in its own waterproof case, which is carry-on luggage on commercial flights.


Gold & Sulphide Minerals

The Gold Sniffer detects gold and minerals from a single measurement on unpolished drill core.

The above image shows the Gold Sniffer’s 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 Gold Sniffer measurement can be used to accelerate gold and mineral exploration, and to increase gold and mineral recovery and profitability for operations at a mine.


Gold Sniffer versus Assay Grade

A comparison of Gold Sniffer gold grades to assay gold grades from 0.5 ppm to 50 ppm which correlate well. The Gold Sniffer grades are an average of 30 Gold Sniffer measurement areas.

Gold in Quartz

The Gold Sniffer 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.
