Camino Rojo is 50 kilometres southeast of the Peñasquito mine in the State of Zacatecas in north-central Mexico. Road transportation and power are convenient, and in this historic mining region, skilled labour and smelters are readily available.

The Represa deposit is situated in a broad alluvial pediment within the eastern Mexican fold-belt, where folded Mesozoic clastic and carbonate sedimentary units have been intruded by intermediate-composition and felsic dikes. The host formation (Caracol Formation) is the same as that peripheral to the diatremes at Peñasquito, which contains world-class Au-Ag-Zn-Pb deposits.
