Combining Classic Mineral Exploration with State of the Art Technology

Liberty Star Uranium & Metals Profile


CUSIP: 53123T206

Why Liberty Star?

1. Potential for discovery of a high grade and large sediment and porphyry hosted copper, gold, and moly ore body of the same type as the nearby Bisbee deposit and other commercially important ore bodies throughout southeast Arizona.

2. Multiple targets over copper-gold anomalies have been plotted using sophisticated ground studies including rock-chip, soil and vegetation geochemical samples assayed for 64 elements by a Certified Assay Laboratory, airborne ZTEM geophysical surveys producing magnetic and electromagnetic data and technical reports from an independent Qualified Geophysicist Geologist.                    

3. Recent discovery of surface copper-mineralized outcrops suggests near surface targets, significantly lowering development time and costs.

4. XRF geochem analysis reinforces sampled data indicating the presence of several EV [electric vehicle] metals in addition to copper: nickel, cobalt, manganese, and scandium. 

About Us

Liberty Star Uranium & Metals Corp. (LBSR: OTCPK) is an Arizona-based mineral exploration company engaged in the acquisition, exploration, and development of mineral properties in Arizona and the SW USA. Currently the company controls properties which are located over what management considers some of North America’s richest mineralized regions for copper, gold, silver, molybdenum (moly), and uranium.


About Tombstone Super Project/Hay Mountain

Tombstone Super Project (TSP) hosts Liberty Star’s premiere multi target property: The Hay Mountain Project. 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, including the Hay Mountain Project, entails a 42-square mile area of interest. The company holds both federal lode mining claims (99) and Arizona Mineral Exploration Permits (5) within this larger area of interest.

Mining throughout the region began in the late 19th Century and led to the rise of legendary silver gold 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). 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, Hay Mountain. If exploration is successful, mining projected for this target would be underground, open-pit, and/or open pit for heap-leach, or in place leach (in-situ) and could produce copper, moly, gold, silver, lead, zinc and potentially other by product metals including uranium & rare earth 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.


Geologic Studies

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 analytical 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 later.

In 2013 Liberty Star contracted Geotech Ltd. To run a ZTEM airborne electromagnetic survey over the Hay Mountain area. Geotech’s final draft report concluded:

1.      There are as many as 10 meaningful targets within the Hay Mountain Project area.

2.      Hay Mountain contains a major anomaly centered on the geochem anomaly reported by Liberty Star (NR 127).
