It seems there are new episodes on again July 2015

They introduced some new people this last episode and the show is getting better IMO. The backstories of the place really add to it, like the curse of that chief on the mine after the workers desecrated some native graves and the subsequent avalanche that killed workers.

I don't know about these so-called "new episodes". I don't know if this is the same everywhere, but I keep seeing obvious 're-runs", but if you read the episodes text, it is being advertised as a "NEW" episode. Maybe it's my own local cable carrier that manufactures that text? I've seen this tactic used in other similar shows as well. It seems to be common now to mislabel episodes as "NEW" in order to deceive viewers.
