When re-discovered in the 19th century, the prehistoric excavations in the Minong Mine area were described as extending "in almost a continuous line for more than two miles, in most instances the pits being so close together as barely to permit their convenient working." A number of ancient mining artifacts were collected from the Minong site; primarily smooth cobbles used as hammers which were, it was said "collected by the cartload." In addition, a fragment of a wooden bowl about three feet across, a wooden shovel, and a rawhide string were also discovered at the site.
