1999-2007: Several prospecting and explorative campaigns have been carried out over the Oscara area since 1999, mostly by Mansfield and later by Regulus. During this period, a regional geological map was generated by Mansfield geologists in addition to detailed mapping over specific areas. A total of 1,010 rock and float samples were taken which highlighted a “horseshoe-shaped” geochemical anomaly around the Cerro Oscara hill. These anomalies are predominantly of Cu and Fe with minor Au, Ag, Mo and Bi.
2008: The Oscara property was transferred to Pachamama Resources Inc. as part of a restructuring of Mansfield.
2012: This property was transferred to Regulus when it merged with Pachamama.
2013-2018: Several field campaigns were conducted by Regulus geologists and 52 samples were collected for geochemical analysis. These samples results confirmed the anomalies previously defined by Mansfield prospectors and geologists
2018: The Oscara project, together with Rio Grande, Aguas Calientes and other early stage Argentina projects, was spun out into Aldebaran.
