Comments on the geologic information

  • PUQUIO PORPHYRY INTRUDES TIBAYA SUPERUNIT AND YURA GROUP AND IS OVERLAIN BY NAZA FORMATION. QUARTZ DIORITE IS THE MAJOR HOST FOR MINERALIZATION.

Economic information about the deposit and operations

Development status Occurrence
Commodity type Metallic
Deposit size Small
Significant No
Discovery year 1982
Discoverer Centromin Geologist

Comments on the reserve resource information

  • GRADE BASED ON COMPOSITE SAMPLES FROM EXTENSIVE TRENCHING WITH MAXIMUM OF 0.5% CU WITHIN THE ZONE OF POTASSIC ALTERATION TO A DEPTH OF 100 M. ROCK GEOCHEMISTRY SUGGESTS AN AVERAGE GRADE OF 0.15% CU, 0.016% MO, AND 0.09 OZ/T SILVER. ONE SAMPLE CONTAINED 0.02 OZ/T AU, ALL OTHERS TRACES.

Comments on development

  • HELICOPTER RECONNAISSANCE AND RECOGNITION OF ALTERED AREA. GEOLOGICAL, GEOPHYSICAL, GEOCHEMICAL EXPLORATION BY CENTROMIN AND USGS (1982-1985).

Subject category Comment text
Deposit STRONGLY ANOMALOUS COPPER CONCENTRATIONS IN ROCKS OCCUR IN AREA 1 X 2.5 KM MORE OR LESS COINCIDENT WITH POTASSIC ALTERATION ZONE; MOLYBDENUM CONCENTRATIONS OCCUR IN SOUTH AND NORTHWEST AREA OF THE COPPER ANOMALY. SILVER MORE OR LESS COINCIDES WITH COPPER. LEAD AND ZINC ANOMALOUS AREAS LIE OUTSIDE THE COPPER AREA. THE PYRITE HALO (FE ANOMALY) OVERLAPS THE COPPER-RICH AREA AND PART OF THE LEAD-ZINC AREA. BORON OVERLAPS IRON-RICH AREAS AND REFLECTS TOURMALINE CONTENT.
