Tombstone Exploration Corp. Renews State Exploration Permit for Section 16 of the Tombstone Mining District

PHOENIX, AZ -- (Marketwired - Aug 6, 2013) - Tombstone Exploration Corporation (OTCQB: TMBXF) (BERLIN: UDNA) announced today that the Company has renewed its state exploration permit for Section 16 in the Tombstone District which encompasses 450 acres. TMBXF also owns patented mining claims totaling 145 acres in this section. All the sections surrounding Section 16 are BLM Claims and owned 100% by the Company.

Section 16, is located two miles southwest of the town of Tombstone, Cochise County, Arizona. The section comprises many of the historical silver producers in the district including: San Pedro group (Fox claims), State of Maine, Merrimac, Free Coinage, Chance, Bonanza, Santa Ana, Solstice, Annex 40 and 41 (Ace-in-the-Hole), Black Horse, the Joseph group, Mamie, Sailor, Randolph, and Groundhog. The total strike length extension of these structures is estimated to be in excess of 7,000 meters.

Mineralized structures are deep seated fracture/fault zones and are considered to be the mineralizing conduits in the District. They trend north-northeast and dip steeply to the west. Other than the fracture filling ore type, manto-type (lensoid, strata-bound) mineralization has been also recognized in the District. The main host rocks are quartzites, and limestones of the Bisbee Group intruded by the Uncle Sam porphyry complex, also a host rock. In general, the fracture filling mineralized structures are mostly associated with the quartzites and Uncle Sam rock units, while the manto-type mineralized structures are predominantly associated with limestones and limey siltstones.

These ore deposits are of polymetallic character, and are predominantly silver-rich, with significant mineralization of gold, lead, zinc and copper. Manganese oxides which are ore carriers and mineral hosts are observed at the upper sectors of the structures.

Alan Brown, President of TMBXF, stated, "We are pleased to be able to renew the key Section of our Land Position in Tombstone. For our new shareholder awareness, we refer below to our news release of January 16, 2008 which discusses our 2007/2008 exploration program."


Phoenix, AZ - January 16, 2008 - Tombstone Exploration Corporation (OTCBB: TMBXF), announced today assay results were received for 115 samples taken from its Tombstone Project property within T20S R22E Sections 16 and 17. The results include rock samples collected from outcrops, mine dumps, trenches, and underground workings. The two highest samples returned assayed values of 609.50 ounces per ton (opt) of Ag (silver), 0.396 opt Au (gold), and 4.28 % Pb; and 81.70 opt Ag, 0.180 opt Au, and 0.20 % Pb respectively. The highest of these samples, sample 49373, was a selected sample collected from the Santa Ana mine (Joseph Vein) workings at the 18 meter level across a 10 cm wide fault. (An earlier - May 2007 - selected high grade sample collected from the 10 meter level of the Santa Ana mine (Joseph Vein), sample SA 35-0, assayed 971.40 opt Ag, 0.335 opt Au and 17% Pb across a 5 cm width. Two additional runs were made as a check on sample SA 35-0 of the Au and Ag values and yielded 0.250 opt Au and 898.70 opt Ag and 0.340 opt Au and 921.10 opt Ag, respectively.) The other high value sample, sample 49376, was collected 48 meters SW of the shaft on the 18 meter level and the sample width is 0.7 meters. The sample pulps from these samples will be re-analyzed by a second laboratory. Six other mineralized grab samples from the 18 meter level of the Santa Ana mine (Joseph Vein) included silver values ranging from 0.05 opt Ag to 3.95 opt Ag. More detailed sampling will be required to further assess the Santa Ana Mine workings. The Joseph Vein is a steeply dipping mineralized shear zone in the Bisbee Group rocks where it is exposed in the Santa Ana mine. A single grab sample from a prospect pit dump collected in the central part Section 17 from the "Bill B" area assayed 4.65 opt Ag, and negligible base metals and Au.

The Tombstone Exploration Project is an exploration and development project within the historic Tombstone Mining District, Cochise County, southeastern Arizona. Detailed studies of the minerals of the Tombstone Mining District have shown a large number and wide assortment of mineralization including silver, gold, copper, lead, and zinc minerals, which have been described along with manganese, tellurium, molybdenum, and vanadium. Although Tombstone is famous for bonanza silver deposits and is essentially a precious-metal district, the porphyry copper model of Lowell and Guilbert (1970) suggests the presence of a buried porphyry copper deposit at depth. TMBXF has the minerals rights to 11,863 acres of historical mining land and is the largest land holder in the Tombstone Mining District.
