The information contained in this circular was gathered by a unit of the WPA Mineral Resource Survey of Texas, a project sponsored by The University of Texas at Austin, Bureau of Economic Geology. The purpose of this survey is to assemble information concerning mineral products and to gather other geological data and make them available to the public. With this information in the hands of the public, it is reasonable to suppose that industries of value to the State may be developed. The following report is based on work done in Travis County by Work Project No.

This report gives the results of a study of barite deposits on the adjoining Freeman and Hillsmeier properties in northern Llano County, where a small tonnage of residual barite has been mined or "gophered" during recent years. The principal objectives were to locate the source of the residual material and to determine the possibilities for commercial development of barite in the area.

With tin near the top of the list of strategic metals, the main purpose of this project was to determine:

The geographic distribution of tin in Mason County.
The source of the tin.
The amount of placer and/or lode tin present per unit volume of sand or vein.
Secondary purposes were to determine what minerals, if any, occurred with the tin, what minerals occurred in the metamorphics rimming the granite, and to search for deposits of magnesite.

Bogs from which peat is being produced commercially in Lee County, Texas, have stimulated, in recent months, the search for more such bogs in various parts of the State. These new peat bogs have served to show the possibilities of the industry; also, they have revealed in part the geological conditions most necessary for the deposition and accumulation of peat.
