Expected Learning outcomes

By the end of this course the participants are expected to:

  1. Appreciate the value of remote sensing in mining organizations
  2. Be able to apply Remote Sensing to Delimit the total area endowed with minerals of interest
  3. Understand the image resolutions appropriate for Geological remote sensing
  4. Understand the fundamentals of spectroscopy and their applications in mineral identification and exploration
  5. Be able to extract geometric properties of an image and use them to support decision on whether to commence mining or determination of expansion areas for existing mines (based on the estimated return on investments (ROI))
  6. Be able to determine the quality of the ore grade likely to be found through indicator minerals identified
  7. Determine hydrothermally altered zones and the minerals controlling the identified alteration patterns
  8. Extract the structural (lineaments) setting of an area and determine their orientations and influence to regional mineralization and present the results using rose diagrams
