The company said it has renewed all of its state exploration permits in the Tombstone Mining District.
The applications for renewal encompass five sections, totaling about 2,600 acres in the mining district.
According to the company, the rocks in these parcels are principally the Bisbee Group sediments and metasediments that have been highly productive in both the Tombstone Mining District and in the Warren (Bisbee) Mining District, Arizona.
Tombstone is focused primarily on exploration and development of mineral resources.
