These are some old mines that were worked and re-worked over the years. “Tin Camp” dates to 1867 and was worked for lead-silver and later for tungsten. The camp is neat for its remaining building that people have taken care of.
The nearby “Brass” mine was worked for gold. Both are fairly remote spots. Sorry for the poor quality of the photos. They were scanned from film taken a while back. I need to revisit the site soon and post an update.
