Kerr Mines Inc. said Oct. 17 that it is acquiring exploration permits covering new exploration targets at its Copperstone gold project in Arizona, potentially adding 541 hectares to the company's permitted 4,775-hectare project.

The new targets were based on geophysical anomalies at Copperstone identified through magnetic imaging, which indicated a low change in the magnetic field potential in four main areas outside of the Copperstone deposit, the Southwest Target and Blue Pearl Targets 1, 2 and 3.

According to Kerr Mines, the new targets are thought to represent detachment faults that could be mineralized like the Copperstone deposit, and the Blue Pearl Targets are similar in magnetic signature to Copperstone and the Southwest Target, which has had successful drill results in the past.
