Shining a new light on mining: developing spectral metrics for decision support in mining exploration and operation

For mining exploration firms and mine operators limited near real-time knowledge of the characteristics of geologic materials manipulated in and around mines impedes the development of efficiencies during exploration and mine exploitation. This applies to the characteristics of drill core, the quality of ore and froth, and the state of tailings. A long-term goal of my program is to meet these needs by conducting fundamental research in the analysis of hyperspectral imagery and later work the findings into an enabling technology. Thus I will conduct studies focusing on three themes: (i) the characterization of drill core mineralogy, (ii) the detection of mine wall alteration and characterization of the ore,  and (iii) the characterization of tailings mineralogy and evaporative state. Integration of these themes along with recent progress from imaging of flotation processes has the potential to provide completely new near real-time decision pathways in mines (from drill core, mine walls to tailings) and in many instances new views of deposits.
