Orestone to start exploring copper-gold project in Chile

Orestone Mining (TSXV: ORS) announced it has started exploration work on its Resguardo copper-gold porphyry project in northern Chile.

In a press release, Orestone said that a geophysical contractor has been mobilized to conduct a 10 line kilometre induced polarization/resistivity geophysical survey or IP at the property. 

According to the company, the program will consist of 5 lines of 2 kilometres each designed to better define the presently identified IP chargeability anomaly and to test for a potential extension to the southwest. 

“The present IP chargeability anomaly has been defined by two lines over a 1000 metre strike length and a width of 300-600 metres starting at a depth of 200 metres with values of 15-30 mv/V,” the miner’s release states. 

The Resguardo project is located 90 kilometres northeast of the city of Copiapó and covers 29 square kilometres of mining concessions. 

Orestone reports that copper-gold mineralization at the property occurs as disseminations and fracture coatings within a 50-100 metre wide vertical fracture zone along a strike length of 1500 metres, open to the southwest.

Historically, copper and gold grading 1-2% and up to 0.60 g/t respectively were mined in a shallow open pit measuring 150 x 60 metres and several tunnels 50 metres below surface.
