A remnant of the stamp foundation from the Rogers Mill is associated with the original mill tests that Daniel C. Jackling conducted in 1898-1899 on ore from this deposit. On the results of these tests, the Utah Copper enterprise was conceived and by January 1, 1949 had produced 9,563,841,413 pounds of copper, with 537,618,374 tons of ore mined and milled and 1,175,639,355 tons of ore and waste removed. This foundation remnant was moved from its original location, probably somewhere in Copperton.
