Phoenix, AZ—September 23, 2015

Tombstone Exploration Corporation (OTCPK: TMBXF), a fully reporting company (Berlin:UDNA), announced today that the Company has staked an additional land position in Yuma County, AZ in the Eagletail Mining District. Sixteen additional BLM Lode Claims encompass 360 acres and surrounds the area, which includes the Stardust Mine that was initially staked in May 2015.

TMBXF has appointed Mr. Rob McEwen as V.P. of Exploration.   Mr. McEwen earned his B.Sc. from the University of Arizona and his M.Sc. from The Colorado School of Mines, where his focus was on economic geology with an emphasis on applied geochemistry.  He has done consulting for major and junior mining companies on a variety of ore types in SW US (porphyry Cu), Mexico (porphyry Cu/Au, epithermal Au/Ag), and the upper Midwest (Cu/Ni).  Mr. McEwen is a member of the Society of Economic Geologists (SEG) and is a Registered Professional Geologist with the American Institute of Professional Geologists (AIPG).

After reviewing reports of previous work done on the property, Mr. McEwen has recommended that further exploration be carried out to not only follow up this previous work, but to expand on it with recently developed exploration methods and mineralization models.  Earlier work focused on precious metals exposed at the surface with a ‘detachment’ style of mineralization, and it is probable that a larger, deeper resource exists on the property.  Early exploration work was done on a broad scale and at shallow depths.

This early work incorporated soil geochemistry, mapping, and shallow drilling.  The geochemistry was done solely for gold/silver/copper results.  No multi-element analysis was done and some of the surface anomalies were never followed up.  Shallow drilling delineated a surface target of approximately 1000’-1500’ by 150’-250’ and depths of up to 100’.  This area is open to the east and west, as well as depth.  Early records show a resource of approximately 2-3M tons with average gold values of 0.06-0.2opt.  Because of the limited work completed, it is recommended that a more extensive, tighter scaled program be undertaken.  Additional claims are being staked, additional research into previous work is being done, and an exploration program is currently being executed.

“We are pleased to have obtained such a committed Geologist with an incredible background in exploration and an extensive knowledge of Porphyry Cu/Au and Epithermal Au/AG projects in the SW USA and Mexico,” commented Alan Brown, President of Tombstone Exploration Corporation. “We are continuing to add key executives to our organization with long-term backgrounds in the resource industry and strong connections within the financial industry. I am confident that this will allow us to continue to implement our exploration initiatives and broaden our resource base in the commodity areas.”
