This part of Arizona is famous for gold mining over the centuries but the Castle Dome mine is unique. Millions of tons of lead and silver have been pushed up by volcanic action into fissures from 3 feet to 20 feet wide which are between 10 and 350 feet below the surface. It is estimated that less than half the ore has been removed.
To see the mine sites we go on a walking tour. At one time a town of thousands of people sat right here. This is one of only a few privately owned mines in Arizona. Modern mining started in 1864 and stopped in 1979. Most of the lead used by the US during the second world war came from this mine.
This shaft is almost 300' deep. Buckets of ore were pulled up this frame by mules. The ore was so rich there were no tailing piles(rock removed to get at the ore). The small amount of rock moved was left in the tunnels. The ore was so heavy that a piece the size of a watermelon weighed over 300 pounds

This is an active mine. Sure doesn't look like what we think a mine should look like. Although this is the richest lead silver mine in North America its not being mined in volume because the closest smelter is in Canada and silver isn't worth enough to justify mining it. The owner is sitting on millions of tons of almost pure lead and silver but its not worth mining. Hard to believe.
Behind Carmen is one of the 30 shafts used over the years to extract ore. Last year a 300 pound chunk of lead silver was found in this shaft. These shafts are about 10 feet wide and go straight down up to 300 feet with no barriers. We stayed on the trail as instructed.
After our hike around the mine we stopped for our usual picnic and a rest. Nothing like a good hike and fresh air to build an appetite.
The owner of the mine has moved most of the buildings from the town site and created a museum using the original buildings and artifacts found around and in the mines. So thats our objective after lunch.
This is one of the miners cabins that they lived in while working the mine. All the items were found in cabins at the site. When they stopped mining they just walked away and left their stuff. I guess most was so worn out that it wasn't worth taking. The dry desert air preserves things; they found a pair of Levi pants in a mine shaft that is the oldest pair ever found dating to 1885.
Carmen found a chair to relax in out of the blazing sun. We're 45 minutes from Yuma; the stage used to take 20 hours. I'm sure she won't be taking the stage.
Here's our group in downtown Castle Dome city. Another great day of exploring.
