Deposit Type

  • Porphyry
  • Vein / narrow vein
  • Skarn
  • Epithermal


Summary:

The Yauli unit region shows mineralization related to polymetallic epithermal systems, replacement bodies and polymetallic vein systems, as well as porphyry mineralization and skarns, thus indicating the great potential of the area.

The newly found Ticlio Cu-Au porphyry prospect is a single granodiorite intrusion showing a pronounced zonation pattern with respect to mineralization and alteration. Its central part is characterized by the occurrence of high density quartz-magnetite±K-feldspar stockwork. The zone rimming the core shows strong K feldspar alteration with low-density magnetite and quartzmagnetite veining. This zone hosts small amounts of chalcopyrite and bornite as disseminations and in veinlets. Native Au is observed as small inclusions in chalcopyrite. The peripheral parts of the system show weak biotite, K-feldspar and actinolite alteration, as well as weak chalcopyrite and pyrite mineralization. The most distal part of the porphyry system is characterized by weak propylitic alteration.

In the central part of the Ticlio porphyry the alteration is represented by strong silicification with moderate to strong magnetite veining. This core zone is rimed by strong K-feldspar alteration grading towards an outer zone of secondary biotite and Kfeldspar.


Mining Methods

  • Sub-level stoping


Summary:

(Translated from Spanish by Google Translate)
Ticlio is an underground mine, a part of Yauli unit.

There was an increase in the Ag head grade by 17% due to higher production of the Ramal Techo vein in the east zone and a decrease in Zn grades by 9% and Pb in 19% due to lower production in the western zone.

Ore production was 34% higher than 2020 production; likewise, the results of production of fine zinc, lead, copper and silver they increased by 23%, 5%, 35% and 60%, respectively. The largest volume of production is due to the contribution of the Ramal Techo vein and the replacement of mineralization in the Roof and Floor boxes.

Production came from using the sublevel stopping method.

The drilling campaign focused on recategorizing indicated resources to measured resources in the Ramal Techo vein. In addition, it made it possible to define disseminated ore in the western area; and in the east, the extension of secondary structures, but with important values of copper and silver.


Crushing and Grinding

Andaychagua's processing plant include grinding circuit consist of primary ball mills #1, 2 (10.5 'x 14', 8 'x 10') and secondary grinding ball mill (7’ x 12’).
