Temperature of region? In modern Scandinavia (cold hills essentially) there is metals such as iron, copper, nickel, zinc, silver and gold. More malleable metals of those are copper, zinc, silver and gold (all able to be melted in a basic bonfire). However in real life, the Turks who conquered Byzantine would use iron cannons that they would melt and re-cast every time they moved. So possible for Dwarves to do the same (which means nomadic wouldn't really be an issue)
In more temperate regions their is similar metals. Iron, copper, zinc, gold but also tin (which means bronze is available). Non metals include fluorite, marble, pyrite, limestone, phosphate rock, coal, Ball clay, lignite and, barite.
In hotter regions copper, gold, diamonds, cobalt, uranium (fun), coltan, tanzanite, ruby, garnet, limestone, soda ash, gypsum, salt, phosphate, dimension stones and graphite can all be found.
Also things like bones and leather and fur could all be used by these dwarves.
This doesn't include materials that only exist in fantasy (such as mithral and adamantine) but that is obviously up to you.
