Controls for ore emplacement

  • Ore Deposits Are An Intricate System Of Veins Along Faults And Shear Zones. Ore Minerals Are Zoned Vertically, With Galena-Quartz Ore Abundant At Higher Levels And Sphalerite-Arsenopyrite-Carbonate More Common At Depth.

Comments on the geologic information

  • COUNTRY ROCK IS SLIGHTLY FOLDED RHYOLITE-TRACHYTE VOLCANIC ROCKS, OVERLYING FOLDED RHYOLITE-RHYODACITE VOLCANICS AND INTRUDED BY BODY OF PORPHYRITIC RHYOLITE AND BY IRREGULAR MASSES OF BRECCIA.

Economic information about the deposit and operations

Development status Producer
Commodity type Metallic
Significant No
Discovery year 1677

Mining district

District name Ticampampa Area

Ownership information

  • Type Owner-Operator
    Owner Anglo-French Silver Mining Co.; Compania Minera Jeccanca
    First year 1904

Comments on the production information

  • REPORTED AMOUNTS ACCURATE AS POSSIBLE. HOWEVER, SIMONS IS DOUBTFUL AS TO RELIABILITY OF DATA PRIOR TO 1949
  • THE PRODUCTION REPORTED IS FROM BOTH COLLARACRA AND HUANCAPETI MINES

Comments on the reserve resource information

  • INSUFFICIENT DATA 3/74 TO MAKE ESTIMATE. METALLOGENIC MAPS OF PERU INDICATE TARICA AS A DEPOSIT CONTAINING BETWEEN 100,000 AND ONE MILLION TONS OF ORE, BUT THE DISTRICT MAY CONTAIN MORE ORE
  • CARPA AND ALSACIA VEINS HAD NO ORE LEFT IN THE ACCESIBLE PARTS OF THE WORKINGS (1947). ORE MINED OUT ABOVE LEVEL 4 IN HUANCAPETI WORKINGS (1947).

Comments on the workings information

  • SURFACE CUTS, ADITS AT 4545, 4600, 4638, 4658, AND 4680 M ON HUANCAPETI VEIN (1947); ADITS AT 4545 AND 4555 M ON ALSACIA VEIN (1947) AND MAIN ADIT AT 4670 M WITH WORKINGS BETWEEN 4640 AND 4710.
