Trail Closures at Empire Mine: Temporary or Permanent?

According to this press release from CA State Parks, managers of Empire Mine will close some trails in the park on a temporary basis. But according to one of the workers at the park who was erecting a fence across the entrance to Conlon Trail (see map), this particular trail closure is permanent.

So what is the deal? The trails affected at Empire essentially includes all the singletrack in the park. Was this worker misinformed? Before I sound the alarm, I will try to get the story straight from Ron Munson (superintendent of Empire Mine) and post the real story here. Of course, trail enthusiasts will want to watch this closely.
