Mr. David Coolbaugh Vice President Asarco Mexicana, S.A. Apartado Postal 38, BIS Mexico 1, D. F.
At the suggestion of Galen Vandell, I am writing to inquire if you can put rae ""on to"" a reference on the la Caridad Copper Deposit.
It has occured to me that something may have been published by the United Nations or a survey organization. Knowing that you personally were connected with the development of la Caridad, you doubtlessly know what, if anything, is in the literature.
From time to time, I give talks at Stanford University on mineral developments and exploration. I'm only trying to ""bone up"" a bit on the la Caridad exploration history, drilling activities, geology, mineralogy, plans and development and any other Mexican data.
One of these days I hope to get to Mexico City and shall of course call you. However, I do plan taking in the S.E.G. Meeting in Washington, D.C. next week. Should you happen to be there, please call rae at the Shoreham Hotel.
With Best Regards,
Weston Bourret Vice President
