Tombstone Files BLM Mining Claims For Eagletail

 

PHOENIX, AZ - Tombstone Exploration Corporation reported that the Company has completed the filing of all of its Bureau of Land Management (BLM) mining claims for the Eagletail Mining District, which is located in the State of Arizona for the year 2016 - 2017. 

During the first and second quarters of 2016, the Company's geological team has identified surface high grade gold results from a detailed mapping and sampling of a mineralized trend in the 100% owned claim block in Yuma County, Arizona in the Eagletail Mining District. Highlights include a sample returning 7.04 g/t gold with multiple other samples above 1 g/t gold of the 70 samples sent for assay.

The encouraging results from the rock sampling program over the Stardust project indicate the presence of a high angle detachment related precious metals vein system. The mineralization present at the Stardust project appears to be located within detachment related veins & locally intensively chloritic and hematite host rocks. The vein system has been sampled over a strike of approximately 3200 feet. These veins appear to be a feeder system of an extensive partially eroded low angle fault system over the Stardust.

The results of the latest tranche of rock samples combined with field observations and existing data appear to fit the USGS detachment fault model of USGS Bulletin 2004 by Long, K.R.: Preliminary Descriptive Deposit Model for Detachment-Fault-Related Mineralization. Other productive detachment fault related precious and base metal systems occur through the Basin and Range areas of Southern California, Western Arizona, and Southern Nevada. An example in Arizona includes the Copperstone Mine, previously mined by Cypress which produced one-half million ounces of gold by open pit methods from 1987-1993. Copperstone is currently being evaluated for additional resources.

Quartz veins present in outcrop, subcrop, float, & in historical mining dumps showcase multi ppm gold values up to 7.04 ppm and silver values up to 22.6 ppm. Eight out of seventy rock samples returned assays above 1 ppm. In addition to these strong precious metal values found in samples, additional observations at Stardust include:

The presence of chalcedonic quartz veins and crushed veins & and multi-phase cemented -- banded silica veins, & silicification

Abundant druse textures (boiling level and vapor phase)

Footwall host rocks are a metasediment matrix with strong hematite & intensive chloritic alteration + copper oxides 

Tombstone Exploration also owns the mineral rights to eight patented lode claims totaling 145 acres in Section 16 along with a State Lease that encompasses the balance of Section 16 in the Tombstone Mining District. Section 16 is located two miles southwest of the town of Tombstone, Cochise County, Arizona. The section comprises many of the historical silver mines 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 of these structures is estimated to be in excess of 7,000 meters.
