This publication attempts to apply much of the geologic, geochemical, geophysical, and mineral occurrence information to a single objective focused on producing a mineral resource assessment for the Commonwealth of Puerto Rico. However, the value of this publication lies not within the results of the mineral resource assessment nor within the interactive PDF files which can be viewed on the screen, but within the geologic, geochemical, geophysical, and mineral occurrence digital map coverages and databases which can be used for their own unique applications. Purpose: The mineral resource assessment of Puerto Rico represents compilation of several decades of mineral investigations and studies. These investigations have been the joint efforts of the U.S. Geological Survey, the Puerto Rico Department of Natural Resources, and the University of Puerto Rico. This report contains not only the mineral-resource assessment, but also much of the scientific evidence upon which the assessment was based. The user may view, navigate, and print on demand any page of the Adobe Portable Document File (PDF) which is included on the CD-ROM. A search tool provided with this file also allows the user to find information anywhere in the database easily. Supplemental_Information: TITLES AND AUTHORS Introduction by Sherman P.

The initial planning by Gregory E. McKelvey (Phelps Dodge Mining Inc.), Norman J Page (USGS), and Ramon Alonzo (DNR) resulted in the mineral-resource assessment of Puerto Rico becoming a project in the U.S. Geological Survey North American Mineral Resource Assessment Program (NAMRAP). The following are some of the many individuals who have made this mineral-resource assessment of Puerto Rico possible. M. Babas, K. Bond, R. P. Briggs, M. W. Doughten, V.A. Langenheim, D. LaRue, J.
