Cerro Rayas Zinc-Lead-Silver Project

The Cerro Rayas Project is made up of 9 concessions held by AU Investments S.A.C. (a subsidiary of Circuit) and is located 196 km SE of Lima, hosts multiple historic Pb-Zn-Ag workings in Mississippi Valley Type (MVT) carbonate replacement deposits. Mineralisation occurs primarily in irregular to lenticular manto-type structures within the carbonate-rich Condorsinga Formation.  The project is in a region rich in polymetallic deposits such as Pukaqaqa, Huajoto, and Tucumachay.

Geologically, the area belongs to the Mesozoic sedimentary belt, dominated by Pucará Group carbonates, intruded by granodioritic and andesitic stocks.
