Centenera owns an extensive northwest Argentina exploration dataset, including results of a proprietary Bulk Leach Extractable Gold ("BLEG") survey conducted in 2007 and 2008 by Cardero Resource Corp. in partnership with Newmont Mining Corporation ("Newmont"). The BLEG data covers prospective areas of Jujuy and Salta Provinces, covering an area of 300 km by 90km and comprising nearly 1,200 sample locations.
Newmont's proprietary BLEG technology is a cornerstone of regional exploration programs, and a continuous program of laboratory comparisons has consistently demonstrated that no commercial alternative can provide its precision and accuracy. BLEG techniques provide a competitive advantage in reconnaissance gold exploration leading to property acquisitions. Newmont credits BLEG with the discovery of its large Batu Hijau porphyry copper-gold deposit in Indonesia and many projects in its exploration pipeline are the direct result of BLEG anomalies.
