Operation type Underground
Development status Producer
Commodity type Metallic
Significant Yes
Discovery year 1950
Mining method Filled Stopes - Horiz Cut and Fill W/Waste Rock
Year of first production 1951
Milling method Gravity

Comments on exploration

  • REGION WAS FIRST EXPLORED IN EARLY 1950. SMALL SCALE CHROMITE MINING HAS BEEN INTERMITTENT SINCE EXPLORATION. UNION CARBIDE OF THE US HAS SHOWN SOME INTEREST IN THIS PROPERTY.

Mining district

District name Kopdag/Erzincan

Ownership information

  • Type Owner-Operator
    Owner Various Ownership In This Region
    Year 1981

Comments on the ownership information

  • THERE ARE SEVERAL ONE-MAN MINING OPERATIONS IN THIS REGION OWNERSHIP-OPERATOR RELATIONSHIP IS UNCLEAR.

Production statistics

  • Year 1980
    Description Ore Input And Output Are 29.24% 10000 Mt Ore/Yr
    Importance Item Commodity Group Amount recovered Grade Recovery percentage
    Major Ore Chromium Chromium 10000mt 29wt-pct

Comments on the production information

  • PRODUCTION WILL INCREASE TO 30000 MT/YEAR IN 1986.

Comments on the reserve resource information

  • IT HAS NOT BEEN POSSIBLE TO OBTAIN A RELIABLE ESTIMATE OF RESERVES FOR EACH OF THE NUMEROUS OREBODIES IN THE AREA. THE TEX REPORT OF 1978 REPORTS RESERVES FOR THE ERZINCAN KOPDAG DISTRICT AS 1.53 MILLION TONNES OF 43% CHROMITE.
  • M1C2 = M9C4. THIS STUDY ESTIMATES 90,000 MT OF CHROMITE AT 43% IN SITU OP PIT MINING AND 910,000 MT OF CHROMITE AT 43% IN SITU FOR UNDERGROUND MINING. TOTAL IS 1,000,000 MT.
