Target Pipeline
The Sombrero Project hosts multiple high-priority Eocene skarn/porphyry targets, categorized into key target areas and individual targets:
Targets:
- Ccascabamba target area includes the Fierrazo, Hojota, Corrales, Corrales Norte, Chumpi, Escondida and Escondida South targets.
- Nioc target area.
- Good Lucky, Uchuy, Totora, Antapampa, Tipicancha, Macha Machay, Milpoc, Ccello, and Rumi targets.
Project Geology and Mineralization
The Sombrero Project is situated in the northwestern extension of Peru’s Andahuaylas-Yauri belt, a region renowned for its Eocene-Oligocene aged copper-gold skarn and porphyry deposits, including Las Bambas, Haquira, Los Chancas, Cotabambas, Constancia, Antapaccay, and Tintaya.
Within the 10-kilometre area spanning from Ccascabamba to Totora, Coppernico has identified four mineralized intrusive centers with associated significant copper and gold values observed in surface sampling. This area is termed the Sombrero intrusive cluster and associated with this cluster are broad zones of anomalous geochemical values, roughly defining an area ~ 18 km by 6 km.
The Eocene aged intrusive complexes with copper (Cu) and gold (Au) metal enrichment cut through a thick package of sedimentary rocks. Where the intrusions intersect more reactive sedimentary rocks (limestone) they often generate skarn alteration with associated Cu-Au (and polymetallic) mineralization. On the property, high-grade skarn mineralization has been documented at Ccascabamba and Nioc target areas in the Ferrobamba limestone. At the Good Lucky target, alteration and mineralization are present in the Gramadal limestone. Intrusions and mineralization are partially exposed as erosional windows through the post-mineralization shallow volcanic cover.

Geochemical Zonation Model with Cover Stripped Back
The Company created a model that removes the volcanic cover from the cluster, revealing combined soils and rocks comparable to Las Bambas and exposing even larger clusters of potential skarn alteration.
