Pretty competitive pay for interns once you factor in overtime (manager dependent) and paid housing. They treat their interns well and its a great introduction to mining.
Cons
There were really no downsides. If you don't like mining you might not like the internship, but that's not Hecla's fault.
Lots of hours (can also be a pro), Middle management intermittently does not do a good job of dealing with conflict resolution. Work Life balance in the Valley is not great.
