A former magnesite occurrence/prospect/mine located in the SE¼NE¼SE¼ sec. 7, and in secs. 8, 17, 18, 20, T19N, R20W, G&SRM, on the West side of the Black Mountains. Discovered in 1943. Owned by Bob Martin, Arizona (1958) and by Harry F. Heather, California (1958). The USGS MRDS database stated accuracy for this locality is 100 meters.
Mineralization is a magnesium deposit hosted in Pliocene rhyolite, trachyte, latite and andesite. Local rocks include Middle Miocene to Oligocene granitic rocks.
The brucite deposits are layers as much as 30 feet thick resting on the Alcyone trachyte, the oldest unit of the mid-upper Tertiary volcanic rock sequence. The deposits are generally overlain by Oatman andesite, but at several places, the brucite layers appear to be within the andesite. Some layers as much as 4 to 5 feet thick, but mostly thinly laminated material of alternating bands of contrasting shades of green, gray, yellow and white. Fresh brucite ranges from serpentine green to light gray to almost white. The brucite is cryptocrystalline and dense with sub-conchoidal fracture.
Regional geologic features include the Black Mountains which are in a tilted fault block in which the volcanic rocks strike northward and dip eastward. At Oatman, the volcanic rocks dip about 12E but to the W they dip more steeply.
Workings include unspecified underground openings. The property was diamond drilled in the 1940's. It was determined that the deposits are too small and too low-grade to be mined profitably.
