TUCSON, Arizona�May 15�Liberty Star Uranium & Metals Corp. (�Liberty Star� or the �Company�) (LBSR: OTCBB) is pleased to provide an update of exploration activity on its Hay Mountain claims.   608 soil samples collected over approximately 22 square miles (NR 114) were sent to the ALS Minerals (ALS-Chemex) certified geochemical analysis lab in Vancouver, British Columbia where they were tested for the presence of 64 different elements. 

 

ALS has returned all of the geochemical soil samples results for all elements requested, to Liberty Star�s Tucson office.  The assays have been entered into an ARC GIS (Geographic Information System) database from which contour maps are being produced.  Additionally, enhanced satellite imagery (digital space photos) is being analyzed for geology and alteration and the various geochemical contours are superimposed on this imagery. This work has produced a variety of interesting and surprising (unexpected) results that require further in depth analysis.  Chief Geologist and Company CEO James A Briscoe and his team have made the following preliminary observations:

 

1.      The common elements of porphyry copper systems are present and provide useful guides, but are subtle.   We are continuing work to analyze these patterns in relation to other technical studies such as aeromagnetics and an IP survey done more than 20 years ago covering a large area. A ZTEM airborne survey is planned later this spring or summer.

 

2.      A surprising presence of rare earth elements (REEs) has been defined over a large area.  This was completely unexpected and justifies further study.  The REEs  we assayed for are among the 17 REEs now known, are strongly anomalous and are scandium, yttrium, lanthanum, and cerium.  The other 13 known REEs were not included in our assay process.  In due course we will re-assay the samples for these additional REEs.  Rare earth elements are critical to various civilian and military hardware and are commercially important. (Wikipedia: �Rare Earth Elements)

 

3.      The REEs are clearly related to a satellite image anomaly as well as geochemical anomalies of iron, uranium, thorium, copper, silver, gold, lead, zinc, nickel, gallium, mercury, potassium, manganese, and molybdenum .  These elements are commonly associated with REE occurrences.    This anomaly covers almost 9 square miles.

 

4.      We are not sure of the meaning of the presence these REEs but the association of the elements named in 3 above justifies further studies.

 

5.      We do not believe the REEs are part of the porphyry system because they are separated in a different area for the most part.

 

The vegetation sample assays are coming in and these results will be plotted just like the soil and rock chip samples have been.  Our interpretation of them will be compared to the other two sample types.  Updates will be reported as progress is made.
