Tombstone Exploration Corporation Confirms Additional Porphyry Targets With Gold-Silver Halos

PHOENIX, AZ--(Marketwire - November 23, 2010) - Tombstone Exploration Corp. (OTCBB: TMBXF) announced today that it has received the completed 2D ZTEM Report for the Tombstone Project from their geophysical contractor, Geotech Ltd. TMBXF is continuing to work with the geophysical data on its Tombstone Project. The ZTEM data indicates there are at least four to five porphyry targets on the Company's property, and there is still a very large land position to review.

Of the targets that have been identified so far, two have precious metal (Gold and Silver) occurrences as "halos" around the properties, which are significant characteristics of porphyry systems. One identified structure has been compared by Geotech Ltd., the world leader in airborne geophysical surveying techniques, to the Mount Milligan deposits that were recently sold and have total measured and indicated resources of 417.1 million tons grading 0.21% copper, 0.41 g/t gold for 1,934 million pounds copper and 5.5 million ounces gold.

Three of the identified targets have coincident magnetic and resistivity high which are very promising geophysical signatures. One target is adjacent to a porphyry system that is currently being drilled by a major international mining company. Mining companies continue to stake available land in the Tombstone Mining District.

Alan Brown, CEO of TMBXF, commented, "This ZTEM report is a significant milestone for the Company as it clearly outlines several large structures. We are impressed with the number and size of the structures and the possibility to host very large gold, silver and copper deposits."

TMBXF continues aggressively to seek joint venture partner(s) to drill these geophysically defined porphyry anomalies. TMBXF is also discussing with industry professionals the strategic direction of the Company.

Tombstone Exploration Corporation (TMBXF) is focused primarily on exploration and development of mineral resources. TMBXF has the mineral rights to historical mining land in the areas around Tombstone, Arizona, and is the largest landholder in the Tombstone Mining District. TMBXF also has the mineral rights to 1000 acres in Mineral County, Nevada, known as the Eagleville property. For more information on the Company, please visit
