Boxy and I recently re-visited this interesting little tungsten mine out in central Nevada. I first visited this mine in 2002.
It was originally discovered in 1945 by W. L. Sovy, Jack Southerland, and Albert Brown. In 1949, it was purchased by J. S. Dougan and associates, who formed the Gabbs Exploration Company. They built a mill in 1952 and it produced over 100,000 tons of tungsten ore until it went idle in 1963. It was quite an operation at the time.
Besides the large open pits, the mine has a 300 foot decline shaft and about a mile of underground workings. Much is still accessible. It made for a fun place to explore.
