MapMark4 Shiny: A self-contained implementation of the MapMark4 R package MapMark4 Shiny: A self-contained implementation of the MapMark4 R package

MapMark4 Shiny is a self-contained R Shiny app designed for quantitative mineral resource assessments. The target audience consists of practitioners of the three-part mineral resource assessment methodology (Singer and Menzie, 2010). The app performs calculations needed to combine information from grade-tonnage models with estimates of undiscovered deposits within permissive tracts. The...
