Shale (a sedimentary rock) transforms naturally into slate (a metamorphic rock) after millions of years of burial deep in the crust under high temperature and pressure. It it not possible to artificially transform shale into slate.
Caves do not form naturally in slate with the possible exception of sea-caves (and then would be inherently unstable) and shallow rock-shelters. Slate mines (entirely artificial) can be very extensive but these are man-made.
