Cobalt cannot currently be obtained by miners, you must find it by disassembling parts. This will be the case for any resource which is "top tier" -- when a new tier is added, it will be possible to "slowly" mine the tier below the top. (Also mythril production will get a boost when the next tier is added as well)
