The Alaska Resource Data File, ARDF, is a database containing information about mines, prospects, and mineral occurrences in Alaska. It is used to here to analyze for the six deposit models. The ARDF records were used to create point feature class ardfcomp_pnt. To score each ARDF location, a list of keywords with weighting factors was created for each deposit model. The results of the keyword searches are contained in the deposit specific point feature classes, such as placer_keywords_ardf. The keyword search scores are used in the analysis for favorable setting for each mineral deposit type in each hydrologic subwatershed. The analyses for the PGE and sandstone uranium deposit models also used lists of specific ARDF sites to score for favorable setting.
