Today, Tombstone Exploration Corp. announced that it has completed the Helicopter-borne time domain electromagnetic GeoPhysical ZTEM program. Selected for its ability to achieve unparalleled resolution and depth of investigation, ZTEM is well suited to image buried porphyry deposits and is capable of gathering data over 6,000 feet (1.25 miles) below ground surface.

The airborne ZTEM survey covered over 200 line miles and most of the Tombstone Mining District. The company expects receipt of the data within the next few weeks. The data will be interpreted to provide targets for a giant, high-grade porphyry copper – gold deposit that can be mined by open pit or block caving mining methods. Tombstone is situated 25 miles north of the historic Bisbee porphyry copper mine. There are numerous ongoing exploration programs in the region for porphyry copper deposits.

The project is also located 150 miles southeast of the Resolution deposit, which is currently being explored by Rio Tinto, and is reported to contain an Inferred Resource of 1.34 billion tonnes containing 1.51% copper and 0.04% molybdenum. The Tombstone project has two major intrusions (granodiorite and porphyry) underlain by sediments that could host a Resolution style deposit.

Alan Brown, CEO of Tombstone, stated, “We are pleased to have completed the GeoPhysical ZTEM program. Once the data has been completely analyzed, we will be able to set our targets for further development of our Tombstone acreage.”
