Tombstone Exploration Corp. announced this morning that it has contracted Geotech Ltd. of Ontario, Canada to fly an airborne Z-Axis Tipper Electromagnetic (ZTEM) on its Tombstone, Arizona property. ZTEM is known for its ability to achieve unparalleled resolution and depth of investigation, capable of gathering data over 6,000 feet (2 kilometers) below ground surface. Geotech arrived at the Tombstone property earlier this week.

The airborne survey will be over 200 line miles, covering most of the Tombstone district. 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 a significant number of exploration programs ongoing in the region for porphyry copper deposits.

The project is situated 150 miles southeast of the Resolution deposit, which is currently being explored by Rio Tinto. The deposit 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, commented, “The ZTEM is the most advanced technology available for discovering ore bodies at depth. To understand this technology further, please view www.geotech.ca. This technology is used by many of the major mining companies in their exploration programs.”

Geotech Ltd. provides full service contract airborne geophysical surveys, data processing and data interpretation. The company currently offers VTEM (helicopter-borne time-domain electromagnetic), ZTEM and AirMt (measure natural alternating magnetic fields in the audio-frequency range), magnetic, magnetic gradient and gamma-ray spectrometer surveys.
