Found some Ferrous Ore and Aluminium Ore while mining in the DW20 pack. The aluminium seems to be used only for making cans or cells for holding liquids, though I assume if gregtech was installed you could use it for other things. I can't find a single use for Ferrous Ore or its products. If pulverized it has a 5% chance for "Shiny Dust" which can make "Shiny Ingots", which according to NEI, can't make anything. Why do these exist?
