As an aside, the benefit of storage in a salt mine is the lack of moisture that's available to interact with the items stored there. The salt absorbs a lot of the moisture and serves to keep humidity fairly constant. As long as the stored items are not directly in contact with the salt, they are unlikely to suffer corrosion problems any worse than if you stored them anywhere else.
The other benefit of a salt mine is that rodents aren't fond of all that salt.
