At first, a ten-pound stamp mill was erected on the property to crush the rock they extracted from the mine. Then in 1906, the National mine was owned and operated by a group of people consisting of eastern capital who named themselves after the gulch which the National mine was located in. They employed Redding resident H.P. Walker as their general manager of operations.
In March of that year, the Rich Gulch Mining Company completed the installation of their brand-new 25-ton cyanide plant, which allowed them to treat the tailing's of the National mine and the nearby Lyons Consolidated mine which they also owned and operated. The company also constructed a 1,500 feet tramway from the Lyons Consolidated mine to the National mine with a gravity system of 460 feet to ship the ore from the Lyons Consolidated mine to the National mine's stamp mill.
The National mine operated until 1910, and then it laid idled until it was reopened in 1932, and it stayed an active producer of gold until 1934. It has been idled since that time period. The National mine produced a total output of $200,000 in gold.
The National mine is located off Shasta Dam Boulevard. I have been informed that there is another caved-in adit on the property which is located at N 40° 41.568 W 122° 25.360 on a very steep and difficult terrain level which is covered in brush, manzanita and tons of poison oak. It would be to difficult for me to get to, which is why I only filmed this portion of the National mine as shown below in the YouTube video:
