Mineral commodity files -- Archdale Office

Introduction

The North Carolina Geological Survey (NCGS) has many older mineral resource commodity files. These literally cover commodities from "A" to "Z".  While these files are by no means comprehensive, they contain a wealth of information. Oftentimes, there is specific information about even individual mines. 

Using your browser, you can "seach" or "find" very specific information from the files listed on this page. For example, you can search for mine or county names, minerals, etc. The Minerals file index table is a good place to start browsing this file; hyperlinks to some ore deposit associations are imbedded in the Minerals file index table and the file listing to make navigation easier. The files themselves are paper. The phosphate files are extensive and cover a large number of topics; these have a subindex linked through the phosphate file list.

These files are in the NCGS' main offices located in the Archdale Building, 5th Floor at 512 North Salisbury Street, Raleigh, NC 27604-1148. The telephone number is (919) 707-9210.

Files are open for public access during regular business hours. Page size copies can be made on site at a nominal page charge of $0.10.  Appointments are highly recommended (see Further Information for details). Refer also to reports of special investigations on mineral processing by the Minerals Research Laboratory.
