Seems to me that this deal must be with us, at least in part (note 'Vendors' not 'Vendor') - and only entails a portion of our overall holdings. Am I missing something here?  

'Tarku’s Tombstone Project 

More recent publications and data compilation concluded that the volcanic geology and structure in the Tombstone area is related to a district-scale Laramide caldera. Mineralization in the district is also related to the caldera and attendant hydrothermal fluid migration. These districts are typically zoned from silver-rich peripheries to higher base-metal and gold contents near to the intrusions. Copper-gold mineralization occurs in intrusion-hosted stockworks or skams.

In the early 70’s, the American Smelting & Refining Company (ASARCO) obtained a lease on the Horne claims around the Robbers’ Roost breccia pipe. They drilled three holes to a maximum depth of 1700m (5,000 ft) on a porphyry copper alteration zone in the vicinity of the breccia pipes. These holes intersected extensive but low-grade mineralization, grading vertically downward from a lead-zinc phase of mineralization into porphyry copper type mineralization, including disseminated pyrite, chalcopyrite, and molybdenite, as well as secondary K-feldspar and purple anhydrite. Poor copper prices at the time and since have discouraged further exploration for copper at this depth.

These mining claims are part of the agreement and such data strongly encourage Tarku’s management to believe the Tombstone Area has the potential to host a significant porphyry copper system with associated gold and silver.'

'Liberty Star Minerals (LBSR) Acquires Permits Over Robbers Roost Near the Hay Mountain Project

Liberty Star Minerals (“Liberty Star” or the “Company”) (OTCPK: LBSR) is pleased to announce the Company has received 2 Mineral Exploration Permits (MEPs) issued by the Arizona State Land Department (ASLD) covering the 240 acre Robbers Roost  exploration area approximately 4.5 miles southwest of Tombstone, Arizona with access via paved road (Charleston Road). The new MEPs are 5.89 miles west of Liberty Star’s Hay Mountain Project for porphyry copper, gold, and molybdenum.

While the Robbers Roost MEP area is new to the Company, it has been explored previously by several exploration companies, in the 1970’s and 1990’s, and recently has received significant interest by others operating in the area.  Drilling by ASARCO indicates “the presence of a granodioritic porphyry intrusive at depth below the alteration zone. The intrusive is characterized by porphyry copper style alteration and mineralization.” [JB Nelson, “Robbers’ Roost Summary Report,” 1995, p. 2  http://docs.azgs.az.gov/SpecColl/2008-01/2008-01-0103.pdf)'
