v8975 we're starting to update to the new blacksmithing, metal desposits for mining will start changing as you will find the new metals that will be available, we're also going to adjust where metal spawns a little so that certain areas aren't the 'best' to go mining for everything but rather you get more reward for exploring everywhere. Some metals will appear in more specific kinds of areas, ie: some metals may appear in more volcanic areas more likely.

These changes are intended to make it more useful and fun to explore when you're looking for resources; the goal is not to make it extremely hard to find anything (outside the fact that copper is more likely and easy to find than platinum). So if something feels way off (too easy to find, or too hard to find) please give feedback so we can adjust and tweak things.
