Press Release

Phoenix, AZ--May 27, 2015

Tombstone Exploration Corporation (OTCQB:TMBXF)  (Berlin:UDNA) announced today that the  Company has staked its initial land position in Yuma County, AZ in the Eagletail Mining District.  The four initial BLM Lode Claims encompass eighty acres and cover the center of a land position, which includes the Stardust Mine (a detailed report was prepared for the property in past years including a sampling program).

The Stardust Property, which is located approximately seventy-five miles west of Phoenix, has a zone of chloritic schist, granite and andesite dikes that have values up to 3.05 ppm gold (0.089 ounces per ton) according to a historic report on the property.  Silicification, limonite, hematite, copper oxide and chloritic alteration are associated with the gold mineralization.

The report states that one of several zones of altered andesite that outcrops from the surrounding sedimentary cover is at least 400 feet wide and 100 feet long.  The overall zone of alteration and fracturing is at least a 1/2 mile in length and 300 to 500 feet wide, but is partially overlain by sediment.  Sixty-three samples assayed over 0.01 ounces per ton.

The report goes on to state that based on available data, there is a good probability that an ore body of +/-3 million tons of 0.06 ounces per ton is present on the property.

Alan Brown, President of Tombstone Exploration stated, “We are pleased to have obtained such a valuable property with extremely valuable gold targets identified in the Eagletail Mining District, Arizona.”
