An Fe occurrence/prospect located in secs. 8, 9 & 15-17, T9N, R15E, about 2 miles NNE of Gentry Mountain and about 1 mile W of the Fort Apache Indian Reservation boundary, approximately 9 air miles E of Young, on National Forest land. Claims extend into secs. 8, 9, 15 & 17. The deposit was known before 1930; during 1960 it was located as the Iron Spike, Iron Prince, and extension groups.

Mineralization is a replacement deposit with an irregular ore body hosted in Mescal Limestone. The ore zone is 2574.8 meters long and 21.34 meters thick. An associated rock unit is diabase.

This deposit is one of many similar hematite occurrences in this part of Gila and Navajo Counties and is considered part of the broad contact-metamorphic replacement of the Mescal Limestone that has been dilated and shattered into a complex of fault blocks by widespread intrusions of diabase.

Assay data: A character sample contained 35.4% Fe, 0.4% Mn, 0.4% TiO2, 0.20% P, 0.08% S, and 37.6% SiO2. A spectrographic analysis indicated the presence of 0.01 to 0.1% Co, Cu, and Ni, and 0.001 to 0.01% V. Other samples contained as much as 57% Fe.

No record of production exists.
