Might actually be worth diving with a cross section area as big as it has.
We were pretty bummed that it was flooded, I'd imagine being that close to the mill it would be pretty extensive; especially with a concrete poured entrance. It's always amazing where you find THAT MUCH WATER in the middle of the friggin desert. They must have either been pumping while operating, or they hit something and flooded it.

I've started wondering if they hooked up with those MASSIVE Vanderbilt workings back there. It's interesting though since the date on the Gold Bar portal is a long time after the demise of Vanderbilt. I'd love to know more about that portal though....

I never made it to the Vanderbilt workings you mentioned. Are they really that "massive?"

If the interweb knows things, we have an answer!
After laying idle for about 7 years, the Gold Bar and Gold Bronze mines at Vanderbilt were leased in 1909 by A. L. White and associates of Ohio. They put the ten-stamp Gold Bronze mill into shape, and it was again running in mid-July. 178
In July, 1910, Mr. C. C. Porter had put in a big cyanide plant and began treating some 7,000 tons that were in the ore dump at the Campbell Mine. He expected to gross about $5 a ton in gold. The next year, in April, a Mr. Sharp, with five others purchased the tailings from the Campbell mill and started treating them. These operations lasted off and on for much of 1911. In the first week of January, 1912, the Pomona Mining and Milling Company began installing a three-stamp mill at Vanderbilt. This company may be the same group represented by Mr. Sharp. By April it was reported they were mining at the Vanderbilt mines, and their mill was running. 179
In March, 1924, the Vanderbilt Mining Company had built new bunk and boarding houses and a completely equipped assay office at Vanderbilt. In addition, a 75-ton ball mill sat on the ground ready to be installed, and two shifts of men were employed sinking the main shaft. 180
In 1929, the property was again leased, and this company shipped about 800 tons of ore which averaged .7 ounce of gold and 3.5 ounces of silver per ton. Another company leased the property in 1934 and 1935 and, upon installing a twenty-five ton flotation plant, began shipping concentrates to the Garfield, Utah smelter. Smaller scale operations continued until 1942. 181
In 1965, Heavy Metals Corporation began drilling the property to determine the extent of the orebodies. Satisfied at their findings, they proceeded to erect a huge mill with a capacity of 500 tons a day. In production from 1969 to 1970 and during 1974 and 1975 about 100,000 tons of ore were treated in the mill from this mine. On February 24, 1978, Transcorp Coporation leased the property and is preparing to mine it.

Part of a much longer piece here. Based on that piece, the Gold Bar Mine was worked from about 1893 to ? (1993 would be my guess with the Desert Protection Act. That explains so many mysteries about this mill.
