Deposit THIS RECORD WAS COMPILED FOR THE INTERNATIONAL STRATEGIC MINERALS INVENTORY. THE DATA WERE USED IN PREPARATION OF THE USGS CIRCULAR 930 SERIES OF REPORTS. MINERAL RESOURCE CATEGORIES AND CODES HEREIN ARE FROM THE INTERNATIONAL CLASSIFICATION SYSTEM RECOMMENDED BY THE UNITED NATIONS GROUP OF EXPERTS ON DEFINITIONS AND TERMINOLOGY FOR MINERAL RESOURCES. (SEE NATIONAL RESOURCES FORUM, V. 4, NO. 3, P. 307-313.). UNDERGROUND WORLD MINING, SEPT. 1977, P.156, REPORTS ABOUT SHIGUELA RESERVES. BESIDES RESERVES OF 46 MILLION TONS, WHICH HAVE ENTERED IN R1E1, ADDITIONAL "PROBABLE RESERVES OF 400 MILLION TONS" ARE MENTIONED FOR THIS SITE. THESE QUANTITIES SHOULD BE ENTERED AS R2S BECAUSE OF GENERALLY LOW CONTENTS
