Comments on the production information

  • NONE NONE
  • CUMULATIVE PRODUCTION BETWEEN 800,000 + 900,000 TONS. GRADE RANGES FROM 0.15 TO 13.0 %. THE ABOVE FIGURES REFER TO THE SOUTHWESTERN GRAPHITE CO. MINE, THE ONLY SIGNIFICANT PRODUCER

Comments on development

  • NON-GEOLOGIC CONSTRAINTS ON DEVELOPMENT OR EXPANSION IN 1-5 YRS. (). DEVELOPMENT(NO); EXPLORATION(YES); ASSESSMENT(THE RELATIVELY LOW GRADE (1.5-4.0 % GRAPHITIC CARBON) MAKES THIS DEPOSIT ECONOMICALLY UNATTRACTIVE); IN 1982, CORONATION RESOURCES STAKED 12 CLAIMS AND DID SOME SURFACE MAPPING AND DRILLING. CORONATION SUBSEQUENTLY DROPPED ITS OPTION. IN 1983, OTHER OPERATORS DRILLED 12 DIAMOND DRILL HOLES TOTALLING 3200 FEET. IN 1982, OTHER OPERATORS, LOOKING FOR GRAPHITE IN THE SAME AREA, CARRIED OUT VERY-LOW-FREQUENCY ELECTROMAGNETIC GEOPHYSICAL SURVEY WORK AND SURFACE MAPPING
  • NON-GEOLOGIC CONSTRAINTS ON DEVELOPMENT OR EXPANSION IN 1-5 YRS. (). DEVELOPMENT(NO); EXPLORATION(NO); ASSESSMENT(NO PROSPECTING OR OTHER ACTIVITY AS OF 1982); MAIN PRODUCER SOUTHWESTERN GRAPHITE CO. MINE, BURNET COUNTY

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.). CORE ANALYSIS SUGGESTS A RELATIVELY LOW GRADE DEPOSIT (1.5-4.0 % GRAPHITIC CARBON)
