PHOENIX, AZ–( EMWPresswire – April 1, 2008) – Tombstone Exploration Corporation (OTCBB: TMBXF) announced today it has conducted geological mapping and sampling

that combined with historical data provided the basis for developing a new

core drilling program. A budget of $1.2 Million has been approved for the

5,200 m core drilling program. Drilling will test an area that is

approximately 900 m by 2,000 m. The program is scheduled to begin in May

2008. Permitting work for the program is currently in progress.

Alan M. Brown, President of Tombstone Exploration, said, “We have approved

the drill program due to the encouraging assay results and the success of

the previous drilling done. The $1.2 million we plan on investing into this

drill program will represent the first ever evaluation below the water

level. I along with our entire management team have the highest

expectations for the results from this drill program.”

The drill program will consist of twenty-three core holes drilled from 15

distinct drill sites that are designed to intercept extensions of the State

Maine Mine, Merrimac zone, Bonanza-Solstice mines, and the

Ace-in-the-Hole-Black Horse mine sub-parallel trends. These zones are

northeasterly trending. Core holes will be HQ size and will be drilled

using triple tube core technology to assure that the most complete core

recovery is achieved. Drill hole spacing will be about 100 m between drill

hole sites. The four mineralized zones will be tested over strike lengths

ranging from 200 m to 500 m.

Eight drill hole sites are planned to have two holes drilled at different

angles along the same direction to intercept their targets at different

depths. Seven sites will have one hole each. The length of the holes

range from 125 m to 320 m and vary in inclination from -45° to -90°. The

holes are designed to penetrate the target zones below the water level. All

available historical data indicates that no mining in the program area was

conducted below the water level.
