According to the Mountain Gazette #85 Silverton did not succeed in BLM approval for full lease operation.
This year they are operating under a temporary permit for guided skiing only. For $99 each per day a maximum of 20 skiers can use the chairlift with a guide.
You could still get an Epic guided ski day given the right conditions. The place sure does sound interesting.
