Although not truly the national industry, with agriculture & fishing filling that bill, the Republic has always recognized mining to be a vital asset to it's survival. Post Cataclysm mining on the island did not start with the Republic however. The original settlers who had come here from Water Point Preserve had a tech level approximately equivalent to the 19th century in sophistication. These mines were vitally important for their survival for attaining building materials, some household supplies, and various impliments that would not be possible without. Some of these original mines are still in action these many years later, but are no where near the scale of many of the new ones.
As of February of 118PA there are ten major mining operations conducted withing the Republic by a half dozen different mining companies. Half are located on the island while the other half are located on the mainland near Taylorville. In addition to these there are at least thirty private operations with fewer than ten employees each in operations on the island. Showing each of the small operations would be a lesson in futility, but the major operations are displayed here;
By all indications the mining of Wa-Daisho will remain a big business issue in the future. Mining expeditions are dispatched about every six months to seek out new mineral deposits and frequently come up with new sites where mining would be profitable. In all reality, however, the large mining corps are bound to get larger. Independant mining will probably continue but will have trouble competing with the large yield mining operations since they will be driving the value of common mineral types down. Those that find a stash of something obscure yet necessary for some element of industry though are still liable to be able to make a bundle even with the threat of the large companies looming overhead.
