Comments on the geologic information

  • ; INGESSANA HILLS IS INTRUDED INTO THE METASEDIMENTARY BASEMENT ROCKS OF SUDAN. IT IS 25 KM IN DIAMETER AND CONSISTS OF SERPENTINIZED DUNITE, TALC-CARBONATE SCHISTS, PERDOTITE, EPIDIORITE, NORITE, AND GABBRO. CHROMITE OCCURS AS LENSES; THEY VARY IN SHAPE, STRIKE NNW, AND HAVE A STEEP DIP. THE LARGEST DEPOSIT MAY CONTAIN UP TO 2 MIL TONS OF ORE. JEBEL KURBA DEPOSIT (11-17N, 33-57E) IS 30 M LONG AND 6 M WIDE, COMPRISING MORE THAN 10 SCATTERED OUTCROPS, VARYING FROM 2-6 M WIDE AND UP TO 30 M LONG. JEBEL CHICY DEPOSIT (11-17N,33-57E) IS BEING EXPLORED BUT NOT MINED AT PRESENT; FOUR CHROMITE LENSES OCCUR HERE. JEBEL JAM DEPOSIT (11-17N,34-00E), THE OLDEST AND LARGEST MINE IN THE AREA, WAS INTRUDED BY A GRANITIC PLUTON ON THE SE SIDE AT BAU.

Comments on the reserve resource information

  • RR1 AND RR2 ARE RESERVES FOR INGESSANA HILLS DISTRICT

Comments on development

  • NON-GEOLOGIC CONSTRAINTS ON DEVELOPMENT OR EXPANSION IN 1-5 YRS. ( TRANSPORT/ACCESS; X; ORE FROM THIS DISTRICT IS EXPORTED THROUGH PORT SUDAN OVER RAILWAY LINE IN NEED OF REPAIR). DEVELOPMENT(YES); EXPLORATION(YES); ASSESSMENT(ESTIMATED LIFE OF MINING AREA AT LEAST 10 YEARS.); YOUNGER ORE HAS GREATER ECONOMIC VALUE. MAIN DEPOSITS ARE JEBEL JAM, JEBEL ABU DAM, JEBEL CHICY, AND JEBEL KURBA MINES. ORE EXPORTED CONTAINS ABOUT 56% CR2O3 (RF2, P. 49). 85% OF TOTAL PRODUCTION IN 1979 ATTRIBUTED TO JEBEL JAM. HOWEVER, MINE IS IN NEED OF MODERNIZATION (RF6, P. 515).

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.). SURFACE-UNDERGROUND IN 1977, THE MITSUBISHI CORP. AND JAPAN METALS AND CHEMICALS CO. INVESTED $50-$60 MILLION IN A FEASIBILITY STUDY OF THIS AREA. IF SUCCESSFUL, THE JOINT-VENTURE COMPANY WOULD BE OWNED AS 51% BY THE SUDANESE GOVERNMENT AND 49% BY THE TWO JAPANESE FIRMS. PRODUCTION IS PLANNED AT BETWEEN 200,000-300,000 MT ORE/YR.
