Open-file Report - 560
Geology and mineral resources of the Ortiz Mine Grant, Santa Fe County, New Mexico

Stephen R. Maynard


This report on the geology of the Ortiz Mine Grant represents a compilation of work carried out by the exploration and development staff of LAC Minerals and Pegasus, along with studies done by the author, Gold Fields Mining Corporation, Conoco, Inc., and C.T. Griswold and G.R. Griswold, and others. The present describes the relationships of the mineral deposits with the stratigraphy and structural geology of the Grant, constrains timing and magnitude of movement on faults in the area, and places these relationships into the broader context of the geology of north-central New Mexico.

This report does not address matters of surface/mineral ownership, or legal descriptions of properties within or bordering the Ortiz Mine Grant.
