The World Leader in Hyperspectral Core Imaging

For decades geologists, mineral explorationists, and mining companies alike have relied largely on the vision and experience of trained geologists to log geological samples. The process is labor intensive and debate prone, with geologists only able to see light in the visible spectrum.

A New Approach to Logging Drill Campaigns

TerraCore’s GeoSpectral Images™ present your core in a new light. Critical minerals and alterations have unique spectral signatures in the Visible to Near Infrared (VNIR) and Short Wave Infrared (SWIR) ranges of the light spectrum. This allows geologists to see mineral alterations, mineral species, abundances and other important features quickly and reliably.

The GeoSpectral Image™ overlaid on the core box photo above shows that the limestone contains interbedded silty limestone with illitic alteration. A small fracture with phengitic illite crosscuts the silty limestone. From 55 ft to 58 ft, quartz dominates the core in conjunction with an increase in decalcification. Phengitic illite is also identified at the end of the box related to an increase in argillization. This suggests that a small structure may have altered the illitic silty limestone to phengitic illite. The siltier and silicic area within the limestone appears to be associated with anomalous gold values. The graph to the right shows the spectra used to identify the minerals.

TerraCore combines the most advanced hyperspectral imaging system with the world’s foremost experts in spectral geology to provide fast, accurate core logging, mineral identification and GeoSpectral Images that let you see more in your core or other drilling samples.
