Hay Mountain/Tombstone Super Project
The Tombstone Super Project (TSP ) hosts Liberty Star’s premiere multi target property: Hay Mountain. The TSP initially consisted of 33 unpatented federal lode mining claims over a projected covered porphyry copper mineral center in Cochise County, Arizona. In 2011 and 2012 more USBLM claims and Arizona Mining Exploration Permits were added after Chief Geologist James Briscoe discovered a large multimodal anomaly over a large covered porphyry copper mineral center within the larger TSP area. Currently, the TSP entails 14.67 square miles of claimed or permitted lands with Hay Mountain covering 13.45 square miles of the area.
Mining throughout the region began in the late 19th Century and led to the rise of legendary boom town Tombstone, Arizona. Many of these mining sites, including what is now Liberty Star’s land, reside within or adjacent to a large volcanic and intrusive geologic feature known as a caldera. These caldera structures are present throughout southern Arizona, making the region one of the richest porphyry copper areas on the planet. By 1938 exploration and development of the Tombstone Mining District in this area was stalled by altered sedimentary rock (hornfels) that was too hard for the drill technology of the day(churn drills).
With copper prices on a continued upward trajectory, and modern mining technology in place, the terrain along this large caldera is again of great interest throughout the mining industry. Through geochemical sampling and computer modeling, Liberty Star founder and Chief Geologist & CEO James Briscoe, discovered a compelling drill target for a very large limestone hosted porphyry copper-replacement deposit. If exploration is successful, mining projected for this target would be underground and could produce copper, moly, gold, silver, lead, zinc and potentially other by product metals. While there are no drilled mineral resources on this property, it is adjacent to the old historic Tombstone Consolidated mines and the target is defined by technical work to allow an immediate start to drill testing. The Tombstone mining district has a well developed infrastructure and enjoys sunny skies over 300 days a year, ideal for year round exploration and mining activities.
In mid March, 2011 Liberty Star contracted SRK Consulting to prepare technical reports over three areas within the Tombstone Super Project : Hay Mountain, Tombstone South and Walnut Creek. Members of SRK’s engineering/scientific staff supervised by Qualified Person and SRK’s Tucson Office Principle Geologist Corolla Hoag, and geologist Dr. Jan Rasmussen have visited the Tombstone property. Their information combined with the previously gathered geochemical, geophysical and computer modeling data underwent a thorough technical analysis. The resulting technical reports concluded that all three claim blocks were worthy of further exploration work.
In 2011 extensive geochemical sampling at Hay Mountain rendered approximately 1,800 soil/rock/vegetation samples which were analyzed for 64 elements at a certified facility in Vancouver, British Columbia. Expected markers for porphyry copper, gold, moly, silver and zinc were present. The geochemical data also yielded the unexpected presence of four of seventeen Rare Earth Elements (REEs). Further analysis of the REE data will be undertaken at a later date.
Liberty Star contracted Geotech Ltd. to run a ZTEM airborne electromagnetic survey over the Hay Mountain area in June/July, 2013. Preliminary findings stated in News Release 165 (October 11, 2013). Other current activities include updating the 2011 SRK technical report for Hay Mountain and the permitting process for five targets.
