The company is continuing to work with the geophysical data on the project, and the ZTEM data indicates there are at least four to five porphyry targets on the company’s property and there is still a very large land position to review.
Of the targets that have been identified so far, two have precious metal (gold and silver) occurrences as ‘halos’ around the properties, which are significant characteristics of porphyry systems.
One identified structure has been compared by Geotech to the Mount Milligan deposits that were recently sold and have total measured and indicated resources of 417.1 million tons grading 0.21% copper, 0.41 g/t gold for 1,934 million pounds copper and 5.5 million ounces gold.
Three of the identified targets have coincident magnetic and resistivity high which are very promising geophysical signatures, the company said.
Tombstone CEO Alan Brown said that this ZTEM report is a significant milestone for the company as it clearly outlines several large structures.
"We are impressed with the number and size of the structures and the possibility to host very large gold, silver and copper deposits," Brown said.
Tombstone is focused primarily on exploration and development of mineral resources.
