Answer 1

We do not know. It is not uncommon to extract salt from the ocean and this is fairly easy to do. But we do not know when people figured this out or when people started mining rock salt. The record of human civilization does not go further back. And we even see animals lick rocks or eat dirt to get salt in their diet. So the practice might be older then humans.
