Plat of the Mooney Mine in El Dorado County, California, about 2 miles northeast of the town of Newton.
In the Mines of El Dorado County by Doug Noble (2002), it is reported that this mine was only worked from 1894 to 1895. There are several other references to the Mooney Mine in Tuolumne County, which was an early Gold Mining claim. The following quote was obtained on line from the Mother Lode Mining Belt
Harvard Mine (Whiskey Hill Mine) is one mile southwest of Jamestown, covering the southeast slope of Whiskey Hill, which owes its prominence to one of the series of massive quartz and ankerite outcrops characteristic of the lode in this county. The group of claims covered nearly a mile along the strike during the period of operation, including the McCann, Mooney, Trio and Sobrante claims and Mooney mill-site.
It was discovered in 1850 and was worked at intervals until October, 1916, since when most of the surface plant has been removed. The Trio and Mooney claims, when worked in early days, produced ore containing about $4.75 a ton in gold and most of the ore has been medium- or low-grade, although one narrow vein at the serpentine contact in the south workings produced a small tonnage of very rich ore.
