You need to keep in mind that Ore generation(that I know of) is only possible mod side, You cannot Use a plugin or anything releated to that to make mod ores spawn, not unless you knew the mods Ore ID's. Ex: IC2:minecraft.CopperOre1 does this make sense? and correct me if I'm wrong. EDIT: I reread what you stated, and now I got you. If the plugin doesn't support mod ores, then you are pretty much out of luck unless its your plugin, sorry.
