Comments on development

  • ECON.COM: THE DRILLING DATA CURRENTLY (1984) AVAILABLE ARE INSUFFIECIENT FOR ACCURATE EVALUATION OF THIS DEPOSIT. FURTHER INVESTIGATIONS RECOMMENDED BY BRGM IN 1968 HAVE NOT (1984) BEEN IMPLEMENTED. HOWEVER, GIVEN THE LOW GRADE OF THE MAGNESITE HERE COMPARED WITH THAT AT ZARGHAT, THERE APPEARS TO BE LITTLE JUSTIFICATION FOR FURTHER WORK.
