ALS Geochemistry Webinar

Hyperspectral instruments allow to capture mineralogical information from geological samples quickly and efficiently, providing great benefits to mine operators for both mining exploration and production projects. Currently, there are systems capable of performing a hyperspectral imaging along boreholes with the acquisition of high-resolution photographs, and they have been widely used in the different stages of mining projects.
