it will also help Ainz with more resources for Nazarick if he invades the dwarfs. For one Nazarick will have more gold, but also give Nazarick greater trade power, so other nations may act with more caution in regards to Nazarick: If Nazarick have lots of minerals like gold and iron other nations need, they may not act against Nazarick for the sake of trade.

To add onto my theory about dwarven blacksmith's and high class metals, there could also be the possibilty of dragons. I was just reminded that there maybe frost dragons in the mountains (just watched episode 8), maybe the dwarves get attacked.
