Indian Creek Limonite
Deposits of limonite with some hematite occur along Indian Creek in the
northwestern part of T. 48 N., R. 6 E., New Mexico principal meridian, about
8 miles east of Sargents up the Marshall Pass and Indian Creek roads (loca-
tion 89, fig. 1). Limonite occurs in small, replacement-type deposits in
Paleozoic Devonian(?) limestone and in small bog-iron deposits along Indian
Creek. The largest deposit was observed in sections 17 and 18, on the Erie
group of uranium claims located by Vulcan Silver-Lead Co., of Gunnison. A
deposit of impure limonite having a maximum thickness of 10 feet is exposed
along a road cut for about 200 feet. A character sample of the better grade
limonite taken by the Bureau of Mines in 1957 assayed 42.6 percent iron, 0.07
percent phosphorus, 0.43 percent sulfur, 20.8 percent silica, and 0.1 percent
manganese, and lost 14.3 percent on ignition.
A spectrographic analysis shows 0.001-0.01 percent gallium, lead, zir-
conium, and chromium, and 0.01-0.1 percent copper, titanium, manganese and
nickel.

Kerber Creek Limonite
Limonite occurs along Kerber Creek and the Bonanza road in approximate
sec. 22, T. 46 N., R. 8 E., New Mexico principal meridian. The deposits are
exposed along the road (location 90, fig. 1) 7.2 miles northwest of Villa
Grove. There has been no production.
Yellow and reddish-to-brown limonite cements sand and cobbles and forms
a breccia with angular to subangular fragments of limestone (fig. 15). In
places the limonite is little more than a coating. A sample of the better
limonitic material taken by the Bureau of Mines October 8, 1957, ran 24.2
percent iron, 0.11 percent phosphorus, 0.34 percent sulfur, 48.6 percent
silica, 0.4 percent manganese, and 6.8 percent loss on ignition.
A spectrographic analysis shows 0.001-0.01 percent copper, gallium,
zirconium, chromium, and molybdenum; 0.01-0.1 percent lead, cobalt, and
nickel; and 0.1-1.0 percent titanium and manganese.
A nearly horizontal deposit of limonitic material is exposed in a road
cut for a length of about 350 feet, a width of about 50 feet, and in thick-
nesses up to 7 feet and perhaps more. It is too low grade to be of commer-
cial value.

Major Creek Limonite Mine
The Major Creek mine (fig. 16), also known as the Moffat and Bennett
mine, is on Major Creek in sec. 8, T. 45 N., R. 11 E., New Mexico principal
meridian (location 91, fig. i). It is about 3 miles southeast of the Orient
mine in the Blake mining district and Rio Grande National Forest. The mine
