Comments on the geologic information

  • ALL VENEZUELAN IRON DEPOSITS OCCUR IN THE IGNEOUS AND METAMORPHIC ROCKS OF THE GUYANA SHIELD AND SPECIFICALLY THE IMATACA FORMATION, WHICH CONSISTS OF GNEISSES, SCHISTS, FINE-GRAINED LAKE SUPERIOR TYPE TACONITES (IN FERRUGINOUS QUARTZITES), AND BRAZILIAN ITABIRITE IRON ORE. THE LATTER HAVE FORMED RICH IRON DEPOSITS THROUGH SECONDARY ENRICHMENT PROCESSES. EMPTY SPACES WERE FORMED THROUGH LEACHING OF THE SILICA, AND WERE THEN REFILLED WITH IRON HYDROXIDES. AFTER FORMATION OF THIS TYPE OF ORE, WEATHERING CAUSED THE SURFACE FORMATION OF A VERY STRONG, HARD LAYER, TERMED THE "CRUST", COVERING THE FINES(TACONITE) AND RANGING IN THICKNESS FROM 1 TO 50 M. THE CRUST IS RICH IN HEMATITE AND CONSTITUTES THE PRINCIPAL ORES, WHICH OCCUR IN CONJUNCTION WITH THE CANGAS (IRON BRECCIAS), WHICH ARE HIGH IN SILICA AND ALUMINA.

Subject category Comment text
Deposit DEPOSIT DIMENSIONS ARE ESTIMATED AT: LENGTH- 900M, AND THE LOS BARRANCOS DEPOSIT LIE IN THE SO-CALLED SAN ISIDRO QUADRANGLE, WHICH IS WITHIN THE LARGER BOLIVAR QUADRANGLE. THE EL TRUENO DEPOSIT HAS NOT BEEN DEVELOPED. FOR THE PURPOSE OF AVAILABILITY ANALYSIS, IT IS ESTIMATED THAT ABOUT $92 MILLION(US 1981$) IN CAPITAL COSTS WOULD BE REQUIRED TO BRING THE DEPOSIT INTO PRODUCTION AT AN ANNUAL RATE OF PIT MINE- $1.80/MT, AND MILL(CRUSH AND SCREEN)-$0.85/MT.
