Tombstone Exploration Continues to Develop and Expand Mining Area

Management to Attend Prospectors & Developers Association of Canada Convention

PHOENIX, AZ--(Marketwire - February 27, 2008) - Tombstone Exploration Corporation (OTCBB: TMBXF) announced today that its Tombstone Project is progressing rapidly through continued work to collect samples from mineralized fracture zones and veins, completion of geological mapping, and property acquisition. Ten mineralized structures known to have been previously worked and several others have been documented.

Samples were collected from the past producing mines and others were from undeveloped structures. 36 samples were collected and they were sent to ALS Chemex for analysis. Standards and blanks have been inserted into the sample stream as a QA/QC procedure. Along with the new samples, 15 pulps were selected from previously analyzed samples and sent to ALS Chemex (as part of routine QA/QC processes) to confirm the original results of the 15 subject samples. The pulps were selected to provide assay result confirmation across a wide range of Ag values both with variable Au and base metal (Cu, Pb, Zn) credits.

TMBXF's applications for acquisition of seven mineral exploration permits covering 1,105 hectares (2,730 acres) have been conditionally approved. These permits will allow TMBXF to explore State lands to the south of the eastern Tombstone mining district.

Surface geological mapping of T20S R22E Sections 10, 15, and 16 is proceeding. This work combined with historical information resulted in documenting potential exploration targets. Historically named mineralized structures that have been mapped by TMBXF are State of Maine, Santa Ana (on Bonanza split), Merrimac, Solstice, and Bonanza. Structures mapped that have not been identified with historical names are Black Horse, Soldier, Ace-in-the-Hole, Rat Trap, and Greenwich.

All of the historical structures are past producing mines and each of the other structures were worked in the past to varying degrees as evidenced by existing shafts and tunnels that were developed on the structures. Exploration along strike and down dip is anticipated. Other mineralized structures were also identified and mapped and will be further evaluated as to their potential as drilling targets.

The management of Tombstone Exploration will be attending the Prospectors & Developers Association of Canada (PDAC 2008) convention being held March 2-5, 2008 at the Metro Toronto Convention Centre.

Tombstone Exploration Corporation (TMBXF) is structured and positioned to capitalize on today's increasing demand and prices for precious metals and base metals such as copper, lead and zinc. Tombstone Exploration Corporation has the mineral rights to approximately 13,500 acres of historical mining land in the areas around Tombstone, Arizona and is now the largest land holder in the Tombstone mining district, which is one of the recent largest mining property acquisitions in Arizona. Through expansion, the Company will acquire new properties, as well as integrate the extraction of precious and base metals. The goal is to produce metals and minerals below standard industry costs.
