DR. D. F. COOLBAUGH
DIRECTOR GENERAL DE EXPLORACIONES
Mr. Weston Bourret,
Utah International Inc.,
550 California Street,
San Francisco, California 94104,
The only things published on La Caridad are my paper (copy enclosed) and a very general reference in the U.N. Publication ""Survey of Metallic Mineral Deposits in Mexico"" United Nations 1969 (DP/SF/UN/19 - Mxico).
We have made a rather complete petrographic study and more detailed geologic information will be published in the future. We have an excellent deposit that geologically fits the ""average"" porphyry picture.
Sincerely, D.F. Coolbaugh

I particularly appreciate your sending me the paper on La Caridad. Little did I realize or appreciate that this deposit represents rediscovery of a known, mineralized area. When time permits, I shall certainly look up the paper by Wandke that appeared in Economic Geology way back in 1925.
Nowadays, we are hearing more and more about metallogenic provinces and the logic of investigating major structural lineaments into unknown areas. Unfortunately though, this kind of exploration takes alot of money and a dedicated, team-effort approach.
Wishing you success bringing the La Caridad Property into production at an early date.
Weston Bourret Vice President
