I did a couple of google searches on silver mines reopening. I found this link of one re-opening in Texas some place. The article also states that it will produce half of the silver of the Green Creeks mine in Alaska which is the largest silver mine in Alaska. Maybe this is the mine you are refering too.
Article mentions they want to hurry to take advantage of the price of silver. Also interesting in that it said the last time it was considered for re-opening was in the days of the Hunt's, but the price collapsed.
