Comments on the geologic information

  • MINERALIZATION OF THE OREBODY CONSISTS OF A DISSEMINATED PORPHYRY TYPE HOSTED BY QUARTZ-DIORITE SUB-VOLCANIC INTRUSIVES. MANY OF THESE HAVE MASSIVE SKARN-TYPE ASSEMBLAGES DEVELOPED AT THE CONTACTS WITH MESOZOIC CARBONATE COUNTRY ROCKS. MAGNETITE IS THE DOMINANT ORE MINERAL IN THE SKARN ASSEMBLAGES WITH ACCESSORY HEMATITE, PYRITE, PYRRHOTITE, CHALEOPYRITE, SPHALERITE, GALENA, BORNITE, AND TETRAHEDRITE. (1989) AS REPORTED IN 1989, HEAD GRADES FOR COPPER AT THE FLORIMUNDA MINE AVERAGE APPROXIMATELY .30% COPPER. THE AVERAGE MOLYBDENUM GRADE IS ONLY .055% AND IS CONSIDERED TO BE ONLY A MINOR BY-PRODUCT. THE ORES ALSO CONTAIN APPROXIMATELY 2 GRAMS PER METRIC TON OF GOLD. THE PORPHYRY SULPHIDE PARAGNESIS IS DOMINATED BY PYRITE WITH ACCESSORY CHALCOPYRITE, MOLYBDENITE, AND TETRAHEDRITE. THE UPPER PORTION OF THE OREBODY IS PARTIALLY OXIDIZED. (1989) BASEMENT FORMATIONS ARE PENETRATED BY DYKES OF LARAMIAN PORPHYRIC GRANODIORITES WITH BIOTITE AND HORNBLENDE. THE SURROUNDING ROCKS, ARGILLACEOUS LIMESTONES, UNDERWENT THERMAL ALTERATIONS AND ALSO PYRO-METASOMATIC AND HYDRO-METASOMATIC ALTERATIONS. (1991) MINERALIZATIONS OCCUR AS IRREGULAR-SHAPED BODIES AND IMPREGNATION ZONES. EVIDENCE LEADS TO THE BELIEF THAT MANY GEOCHEMICAL AND GEOPHYSICAL ANOMALIES TOOK PLACE. (1991) MOST RUMANIAN COPPER MINES ARE GENERALLY LOW GRADE AND MINERALOGICALLY COMPLEX. (1989)

Comments on the ownership information

  • THE FLORIMUNDA MINE IS OWNED ENTIRELY BY THE GOVERNMENT OF ROMANIA WHILE THE DEVA MINING COMPLEX IS IN CHARGE OF OPERATION.

Comments on the production information

  • IN THE 1989 REVIEW BY COMMODITIES RESEARCH UNIT LIMITED, NO PRODUCTION RATES WERE GIVEN FOR THE FLORIMUNDA MINE. ALSO, NO CONCENTRATION RATES, CONCENTRATION GRADES, OR FLOTATION RECOVERY RATES WERE SUPPLIED. ACCORDING TO COMMODITIES RESEARCH UNIT LIMITED IN 1990, THE FLORIMUNDA MINE IS A NON-VIABLE OPERATION. THE RESEARCH UNIT SPECULATES THAT THE MINE WILL SOON BE FORCED TO CLOSE DUE TO INTERNATIONAL PRESSURES. THEY ALSO SUGGEST THAT THE TWO COPPER SMELTERS IN ROMANIA TO BE MEDIUM TERM CLOSURES. THIS IS BECAUSE OF THEIR REMOTENESS FROM A SEA PORT AND THE UNLIKELY UPGRADING TO CONFORM TO ENVIRONMENTAL NEEDS. MOLYBDENUM CONCENTRATES ARE TREATED AT A SMALL HYDROMETALLURGICAL TREATMENT PLANT NEAR MOLDOVA NOUA. (1989) AS OF 1989, COPPER CONCENTRATE, PYRITE CONCENTRATE, AND MOLYBDENUM CONCENTRATE ARE THE MAJOR PRODUCTS OF THE MINING OPERATIONS.

Comments on the reserve resource information

  • THE ESTIMATED RESERVES IN 1989 WERE DETERMINED TO BE APPROXIMATELY 300 TO 400 MILLION METRIC TONS, REFERRING TO TOTAL RESERVES FOR THE MOLDOVA NOUA DISTRICT.

Comments on other economic factors

  • THE MINING EQUIPMENT USED AT THE MINE SITE, AS OF 1989, IS REPORTED TO BE PRIMARILY ROMANIAN MANUFACTURED. THE CONDITION OF THE EQUIPMENT IS EXTREMELY OUTDATED, POORLY MAINTAINED, AND IN MANY CASES, OBSOLETE. AS OF 1989, THE ORE EXTRACTED, EXCLUDING MOLYBDENUM AND GOLD, IS TRANSPORTED TO THE ZLATNA COPPER REFINERY.
  • THE CAPACITY AT THE CONCENTRATOR WAS DETERMINED TO BE 107 DRY METRIC TONS OF ORE PER DAY.(1991)
