Hi Juanly.Good to hear from you.I have talked to people in Box Elder county.They know of no gold there.Years ago there was a little placer gold in a stream there.I panned gold in Clear Creek in Colorado.They find gold from that stream 500 miles away out in the desert.So no telling where the small bit of gold in Box Elder streams came from.A table from the county of the people job sources, doen't list 1 persom mining there.A few orther countys have gold in Utah.Most of the gold from is by products of other type mining.
