Tombstone Exploration Corporation's Core From Drill Hole #1 and First 120' of Drill Hole #2 Being Assayed

PHOENIX, AZ--(Marketwire - August 5, 2008) - Tombstone Exploration Corporation (OTCBB: TMBXF) today reported that drill hole TEMC 101 was completed at 980'. Recovery remained exceptionally high due to the triple technology, and the RQD rate in most instances was over 75%. Core has been photographed, diamond split and sent for assay to ALS Chemex.

Drill hole TEMC 102 is under way and is currently at 300'. TEMC 102 is designed to intercept the Santa Ana structure. Ore intercepts are hosted by sedimentary rock units as limestones, siltstones and quartzites of the Bisbee Group with minor occurrences of granitic associated with the Uncle Sam porphyry and feldspar porphyry dikes. Most of mineralization occurs in thin manganese oxide veins of 2-5' (apparent thickness) taking place at a rate of 10-15' apart with wide alteration haloes of argillic alteration and minor silicification along the veins. In most instances, abundant manganese oxide stringers are placed along the alteration haloes. This zone extends in excess of 150'. It is inferred that the manganese oxides carry significant amounts of silver mineralization, which is the case of the historical mineralization observed at the Tombstone silver mining district.

The upper 120' of core has been logged, photographed, diamond split and sent for assay to ALS Chemex. Recovery is considered acceptable, despite the fact that it is strongly affected by faulting. Actually veins are placed along fault and fracture zone in most cases. RQD rate at the ore zones is normally lower than 25%.

Alan Brown, President and CEO of Tombstone Exploration, stated, "The assay results of TEMC 101 and TEMC 102 will be reported as soon as available. We are encouraged with what has been found to date in both drill holes, particularly the prospect for silver."
