Mining

The most mineral rich nations in terms of raw deposits are Svitgard, Osterbija, parts of the Kaselreich and Dace. Lagoria used to have some of the most colossal gold mines in the world, but these ran dry centuries ago.
Dace's chief mineral resources are iron, copper, and silver. They have no problem arming themselves--the chief problem they face is convincing people to buy iron, which is what they have the most of. For years they have been trying to develop an industry in steel goods, but the expertise simply wasn't there until very recently. Cheap, simple axes and shovels produced in Dace can be found just about anywhere on the continent, though. And just recently, Taphonomy Bay has finished the construction of an enormous cannon foundry, determined to prove that Steel is TOO a viable metal for cannons, and cheaper than bronze. Very mediocre standardized handgonnes have also been produced in Dace for several years by the Racoco Factory.
Most gold these days is procured by Jenoesa, who suspect that there are great mines deeper into the Tujanci lands, but cannot get at them just yet.
Tin is produced mostly in the Slivers and in Osterbija.
In the parts of Iber which were once provinces of the Ruvian Empire, there was an interesting practice which took place--rich gold reserves located in mountains were mined using enormous gangs of slaves, who were worked--mostly to death--pounding away deep into the mountains and hills to extract as much ore in bulk as possible, even sifting through the dust produced to extract every trace of the precious metal possible.
This resulted in titanic networks of tunnels bored through many of the hills in the country, some going deep underground using water pressure to smash open chambers and later extracting it using simple pumps, also powered by slaves. It is said that when slaves were worked to death in the great processing facilities, their bodies were unceremoniously dumped into the emptied tunnels. Indeed, going down deep into these systems, one can still find chambers filled with nothing but bones, clay, and long-decayed mining tools.
These hills are called Las Colinas Malditas, or "The Cursed Hills," and a great variety of dark legends surround them, including stories of necromancers venturing inside for raw materials, and of bandits, monsters or worse using them as hideouts.
