A former surface Au-Ag-Hg placer deposit area located in the sec. 25, T.20S.,R.9E., secs. 30, 31 & 32, T.20S., R.10E., & sec. 5, T.21S., R.10E., Las Guijas Mountains vicinity, immediately NW of Arivaca, and about 50 miles SSW of Tucson. Started in the 1860's. Owned by the New Venture Placer Mining Co.
Mineralization is generally very fine gold with a few nuggets in gravels on pediment slopes, old terraces or 'mesas', and in verious gulches and washes along Las Guijas Wash at or near true of false bedrock. Often admixed with clay.
Workings include dry and wet placer operations from prior to 1900. Reworked intermittently in the 1930's and early 1940's. Total production is estimated at about 1,000 oz. Au with some Ag.
