Tombstone Exploration Corporation (OTCBB: TMBXF) announced that its staff has identified three exploration strategic priorities for advancing near-term value and long term economic potential on its Tombstone, Arizona properties. Geologic mapping and sampling during the last week of March 2009, located mineralization supporting the underlying concepts behind these strategies. Chlorargerite (a high-grade silver ore mineral), fine grained silicification and low manganese content was found in outcrops and mine dumps, an alteration pattern consistent with the highest grade ores in the Western Tombstone Mining District, and three samples have been submitted to Copper State Analytical Laboratories in Prescott, Arizona, for silver, gold, copper, lead, zinc, and manganese assays.

Alan Brown, President & CEO of Tombstone, stated, "Previous mining and exploration efforts in the Western Tombstone District have focused on ore bearing structures that were exposed on the surface, and mining activities throughout the area stopped at or near the shallow water table due to insufficient pumping technologies at the time. Historical operations were also hampered by lack of economical processing methods for lower grade ore, such as the effective heap leach technologies used and developed in Tombstone in the 1980s. One part of our exploration strategy is ore deposits buried beneath alluvial cover or otherwise not exposed, that were overlooked by historical prospecting efforts. A near surface ore body will allow for rapid initiation of mining and metal production, and will be amenable to low-cost heap leach processing that requires minimal infrastructure and environmental impact."

The longer term focus of exploration work will be to locate two specific geologic targets repeated throughout the area. These two targets have been developed through detailed analysis of the geologic conditions in historically producing mines in the Tombstone area.
