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
The Resguardo project is located in the Middle Tertiary porphyry copper belt, which hosts Codelco’s El Salvador and Potrerillos mines
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
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
