Greater Riqueza

Riqueza is a Zn-Ag-Pb-Au-Cu focused project located within a part of Peru’s mineral belt called the Miocene Porphyry-skarn Mineral Belt and the Chonta Mineral Belt more locally. This northwest-southeast belt hosts numerous porphyry and skarn deposits, several large mines and dozens of smaller mines.

Riqueza is highly prospective for porphyry and porphyry-related mineralisation including: Zn-Ag-Pb vein, breccia, manto replacements mineralisation; Cu skarn replacement mineralisation; and Au-Ag epithermal mineralisation. All three forms of mineralisation are already known at Riqueza.

Importantly, there are three known porphyries within 20km of Riqueza and all of these have mineralisation related to them.

Exploration conducted by Inca at Riqueza to date has identified an intrusive-related mineralised system covering a 25 square kilometre area. Geophysics has identified several large porphyry and porphyry-skarn targets within this area. Inca has delineated innumerable vein, stockwork, breccia and manto Zn-Ag-Pb carbonate replacement deposits (CRD), high-sulphidation vein and stockwork Au-Ag occurrences and a skarn Cu occurrence.

Riqueza is surrounded by mining infrastructure. A powerline supplying electricity to the Heraldos Negros Mine comes to within eight kilometres of Riqueza. Within haulage distance of Riqueza, there are three treatment plants, two of which can produce Zn and Pb-Ag concentrates. The project has all-weather access and there is an ample water supply.
