The \u201cAll_pre_1981mines.shp\u201d contains all the data points including areas not related to sand, gravel, and aggregate resources. Therefore, the additional layers were included as subsets of this dataset and include sand, gravel, borrow, sandstone, silica sand, volcanics, clay and shale, crushed rock, decomposed granite, dolomite, limestone, and perlite.
