The Tintic Mining Company started a mine in 1919 on the East side of Genola, Utah. They did not want to send their ore to another smelter to be processed so they built their own just South of town using the natural slope of the side of a hill to use gravity to help with the process. They connected the 2 locations with a rail road which can still be seen today, although it is no longer close to usable. The mill was used to smelt silver, copper, lead, and even gold. The water from the nearby springs were used to aid in the process, but the waters were badly contaminated but the heavy metals that were being processed and the water is now dangerous to even swim in.
It was abandoned in 1925, only 5 years after it was built. Unfortunately, the reduction process they were using for smelting was already out of date when they started building the mill, they could only process about half the ore that was being pulled from the nearby mine per day. After only a few years, the realization that the mill could not keep up with their production was accepted and they started using a 3rd party smelter and shut this location down.
Is it publicly accessible?
It was closed to the public a few years ago after people were getting arsenic poisoning from swimming in the hot springs at the bottom. It is now accessible, but not by motorized vehicles. You can park about a 5-10 minute hike from the mill.
The GPS coordinance for the mill is 39°57'26"N 111°51'10"W or 39.957222, -111.852778. There is no actual address any more, it is on a road that used to cross Hwy 6 but has been blocked off. The easiest way to get there is to take I-15 to Santaquin and head West about 10 or 15 minutes. It used to be part of State Street in Genola, Utah, but is now nothing more than an access road for a couple of houses which are located at approximately 1430 S State Street, Genola, UT 84655. Goshen is a few minutes West and the best way to view the mill is driving East from Goshen on Hwy 6 where you will see the mill against the hill like a castle.
You can watch a short video about this mill and the mine it was built to assist on YouTube. It was produced by the Mojave Underground, a mine exploration team out of Utah:
