PepinNini Minerals (ASX: PNN) has uncovered high grade copper and gold through surface sampling at its Santa Ines Project in Argentina, which lies along the same structural corridor that hosts BHP Billiton’s (ASX: BHP) 5 billion tonne Escondida copper-gold porphyry deposit.
The 82 square kilometre project is strategically located just 5 kilometres from the Salta-Antofagasta railway and is easily accessed using existing roads and tracks.
Santa Ines lays within a crustal scale northwest trending mega-lineament, which is widely recognised as being a major long-lived structural corridor fundamental in the control of the distribution of porphyry-epithermal deposits.
Known mineralisation along this lineament to the immediate southeast of Santa Ines includes the 2.2 million ounce Lindero Gold Porphyry project, which is currently in Feasibility, and advanced copper-gold exploration projects including Rio Grande, Arizario and Samenta.
The grab samples, which were collected from a historic mine working returned grades of up to 21.7% copper and 0.91 grams per tonne gold, confirming the potential for high grade copper and gold mineralisation at Santa Ines.
There is no evidence of any modern exploration work having been undertaken at Santa Ines and no historical data is available.
PepinNini plans to target a number of potential mineralisation models including porphyry-epithermal style deposits and iron-oxide copper-gold targets at depth.
