Subject category Comment text
Deposit ROMERAL ORE DEPOSIT IS LOCATED IN THE COAST AS ARE THE MAJORITY OF THE OTHER IMPORTANT IRON ORE DEPOSITS IN CHILE. THE DEPOSIT MIGHT ALSO BE CONSIDERED TO BE IN THE LOWER FOOTHILLS OF THE ANDES RANGE SINCE IT IS DIFFICULT IN THIS SECTION OF CHILE TO RECOGNIZE THE COAST RANGE AS A SEPARATE RANGE FROM THE ANDES. THE COAST RANGE, OR THESE LOWER FOOTHILLS CONSISTS OF A CORE OF OLD BASALT ROCKS, SYENITES, DIORITES, GNEISSES AND SCHISTS. THE ROMERAL DEPOSITS FORM THREE LOW LYING HILLS WHICH EXTEND IN A NORTH AND SOUTH DIRECTION. THE SOUTHERN HILL HAS AN ELEVATION ABOVE SEA LEVEL OF 392 METRES, THE MAIN OR CENTRAL HILL AND THE NORTHERN HILL BEING 446 AND 494 METRES HIGH RESPECTIVELY. THE ORE IS EXPOSED INTERMITTENTLY FOR A DISTANCE OF TWO KILOMETRES OVER THESE HILLS. THE CENTRAL HILL IS THE MOST IMPORTANT OF THE THREE, ORE BEING EXPOSED CONTINUOUSLY FOR OVER 500 METRES IN A NORTH AND SOUTH DIRECTION. THE ORE WHICH IS FOUND IN THIS PRINCIPAL OREBODY IS LARGELY UNALTERED MAGNETITE. IT DOES NOT OCCUR IN A SOLID MASS, BUT IS FOUND AS A SERIES OF MORE OR LESS PARALLEL LENSES SEPARATED BY ANDESITE. SMALL VEINS OF CALCITE OR QUARTZ ALSO CUT THE ORE IN PLACES. DRILLING HAS INDICATED THAT PORTIONS OF THE OREBODY EXTEND TO A DEPTH OF OVER 400 METRES. STRIPPING IS MAINLY IN THE LOWER GRADE (+/- 37 PCT FE) ROCK, WHICH IS BEING STOCK PILED FOR FUTURE USE. THE CONCENTRATES ARE HAULED ABOUT 29 KM TO THE PORT OF GUAYACAN ON A NARROW GUAGE RAILWAY. IN ADDITION TO THE OPERATING COSTS IT IS ESTIMATED THAT ABOUT $6 MILLION (1981 $) PER YEAR IS REQUIRED TO MAINTAIN THE CAPITAL EQUIPMENT AND FACILITIES.
