no need for a mod, if you just handwave in the ore you want with a console command.
or handwave in the black metal pick, and its pretty much 1-2 hit per bust until mistlands. Note that skillup with it will slow down a new character, but once you get ~50 skill its more or less as you want. New character with antler pick is a double whammy, skill and tool both low, and it sucks for a while.
