“…Since 1983, much has changed. Prospector II, the successor to Prospector, has been developed at the U.S. Geological Survey (McCammon, 1989). Two major devel-6 opments have included (1) the format used to represent deposit models, and (2) the algorithm used to classify mineral occurrences, prospects, and deposits.…”
