General Setting

• Located 35 km to the NE of Palpa and

approximately 350 km SE of Lima

• 1,800 ha in three mining concessions

• Elevations range from 1,500 m to

2,500 m

• Western Peruvian Cretaceous and

Lower Tertiary Cu-Mo porphyry belt

• The belt host world class copper

deposits as Toquepala, Cuajone,

Quellaveco and Cerro Verde

Mineralization

• Leach cap (30 m to 80 m)

• Oxide blanket with malachite,

crisocolla, azurite and black copper

oxides (tenorite and neotocite)

(5 m to 20 m)

• Supergene enriched blanket with

chalcocite and minor covelite

(10 m to 40 m)

• Primary mineralization with

chalcopyrite, pyrite and minor

bornite

• High pyrite-chalcopyrite ratio
