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.

During 2019, production was mainly from the Ramal Techo Vein, especially the deepening pits, 61% production was from the exploitation by Sub Level Stoping, carried out in structures such as the East and West Ramal Techo Vein, Julissa, Kelly and Replacement.

The production of tons of mineral from Ticlio decreased by 29.17% compared to 2018, while in terms of fines the production of Zn, Pb and Ag decreased by 41.97%, 57.35% and 12.52% respectively.

This was impacted because there was no mine prepared for 2019, mainly in the West area of Ramal Techo (high Zn grade), and in the process there were pumping system failures, which restricted the advance of the ramp of Deepening, an important factor was also the low availability of the fleet of mine equipment, likewise the change of Contractor had a long period in the adaptation and learning curve in the operation.

The resource estimate in 2019 was higher than that reported in the 2018 period, and DDH drilling in the 2019 period increased compared to 2018, which has allowed the definition of the Replacement structure, as well as the reinterpretation of existing veins as Veta Ramal Ceiling at depth.

It was also possible to conclude the interior communication project Mine integrated with surface (Radios Tetra), with which the mine is 100% integrated in radio communication.
