This mod lets you designate all connected minerals to be mined, even if you can't see them.
Works on any mineable tile including stone.
V1.2
increased compatabilitty, removed DesignationCategoryDef & swapped to xpath patching it (At Menhi's suggestion)
V1.1
Updated to R1 and I think I fixed the crashing bugs though veinmining stone usually does a weird pattern on large mountains.
V1.0
Initial release
Obselete as of RimWorld 1.5, as a similar feature has been added to vanilla
