Great Southern Copper PLC announced the completion of the first ground magnetic survey on its San Lorenzo copper-gold project located in the coastal cordillera belt, Chile. The results of the survey are expected to assist GSC with its project-scale geological interpretation and, ultimately, to define and model various drill targets. The surveyed area comprises the Cerro Blanco - Cerro Chinchillon region in the northern area of the San Lorenzo project and incorporates the Cerro Blanco, Las Hermanas, Chinchillon, San Miguel and Perseverencia prospect zones which collectively comprise GSC's primary alkalic porphyry Cu-Au target area.

The survey was conducted by ENFI Chile and the data generated will be processed by Exploregeo (Perth, Australia). The ground-based survey covers an area of 63.36 km2 comprising forty-five E-W profiles each 7.2 km long and spaced 200m apart plus two N-S control tie lines of 8.8 km length. The survey utilized two latest generation Gem Systems magnetometers running Overhauser System which records every second in WalkMag mode collecting simultaneous magnetic field and topography data using differential GPS.
