Figure Lengend Snippet: ProSpecTIR-VS scanner in custom configuration on rotating turntable in the vehicle for mine-wall (outcrop) scanning. The short-wave infrared (SWIR) instrument is on the left side of the box (round lens). The visible and near-infrared (VNIR) instrument is behind the rectangular port on the right.

Figure Lengend Snippet: Comparison of the ProSpecTIR short-wave infrared (SWIR) mineral map for the bottom of the Trinity Mine pit (extracted from ) to 3D plot of mined silver ore grade. Colours on mineral map (a) match . Red and magenta colours on ore grade plot (b) indicate higher silver grades. Note apparent partial correspondence at approximate location ‘?’ between bottom of mined high-grade ore in (b) and the centre part of the jarosite zone shown in (a). North–south index lines on (a) run from upper right to lower left and (b) shown in approximately the same orientation.
