Tombstone Exploration Closes Private Placement and Summarizes Property Holdings

Tombstone Exploration Corporation (OTCBB: TMBXF) is pleased to announce the closing today of its non-brokered private placement of 2.5 million common shares at a price of $0.20 per share, for gross proceeds of $500,000. Each purchaser also received a three (3) year, half share warrant to purchase additional shares at $0.40. Finders' fees of $35,000, converted into 175,000 shares of common stock, were paid in connection with the private placement.

The proceeds of this offering will be used to continue the Company's drilling and exploration program, geologic mapping, surface trenching, sampling and for general working capital requirements at its properties in the Tombstone District in Arizona. The Tombstone project property consists of 319 unpatented mining claims on BLM administered lands that were acquired December 1, 2006. Seven exploration permits, encompassing 3,071.59 acres, from the Arizona State Land Department were obtained on April 17, 2007 that are renewable up to five years and may be converted to mineral leases if mineral is of sufficient grade to be mineable is demonstrated.

Tombstone Exploration Corporation also acquired the mineral rights February 17, 2007 to over 145 acres. Included in the acquisition were the mineral rights to the State of Maine mine. It is the most important past producing mine in the Western Area of the Tombstone Mining District. A historical report, "Report on The Mellgren Mines Tombstone Mining District Cochise County Arizona," that is non-compliant with NI 43-101 and was prepared in June 1928 by C. J. Sarle, PhD., stated the following:

"The early work done on the State of Maine, San Pedro and Chance Mines was with no better equipment than a steam hoist and hand steel. In this way silver-gold ore, as earlier stated to the gross value of $3,500,000.00, was taken from the State of Maine."

Sarle also indicated that the workings in the western area did not extend below the water level and the ores were oxides.

According to B.S. Butler, et.al. reporting in University of Arizona Bulletin Vol. IX, No. 1 -- Geology and Ore Deposits of the Tombstone District, Arizona (Jan. 1938) the State of Maine was mined for 480 feet along an inclined vein and for 900 feet along strike. The vertical depth of the State of Maine reached was 325 feet from the shaft collar.
