Mods are not necessary, just adding worker's barracks and leveling up your industry area will do that, as well as adding maintenance buildings increase internal storage of your extractors and processors.

A for instance is, a level 1 large ore mine can produce 11.2k worth of ore per week. A level 5 large ore mine, with 20 worker's barracks will produce 25,984 units worth of ore per week. Just one of those requires at least 5 raw ore storage buildings (looks like a woman's breast) to store said ore. Of course, that is as long as they are on a strong ore deposit (you should be using unlimited ore and oil for those industries as well).
