Tucson, Arizona – May 6, 2010 - Liberty Star Uranium & Metals Corp. (the “Company,” LBSR: OTCBB) is pleased to announce that it has received the completed 2D inversion for every other line for the 1256 line kilometers of the ZTEM survey database. The 2D inversion data is modeled in 3D and will provide the Company’s geological and geophysical team with data to precisely define promising anomalies. In these areas all lines will be processed for 2D inversions and 3D models will be prepared. Final interpretation will be performed to pick the best targets for subsequent drill testing at the South Block on the Company’s Big Chunk Super Project (BCSP) in southwestern Alaska.

 

In June 2009 the Company contracted Geotech Ltd. (Aurora, Ontario, Canada) to conduct helicopter-borne ZTEM surveys over the South Block of the BCSP claims area. This electromagnetic (EM) method can gather data as much as 2 kilometers (about 6 thousand feet) below the Earth’s surface to identify geophysical features associated with mineral systems. By April 2010 Geotech had delivered a database for the 1D ZTEM geophysical data for all 1256 line kilometers (780.4 miles) in north-south lines spaced 250 meters apart, covering 315.2 sq kilometers (121.7 sq miles). At that time, the one line that had a 2D inversion performed on it showed that it crosses a circular EM feature consistent with a typical porphyry copper system defined in original testing of the ZTEM system in southeastern Arizona. That 2D model shows a typical low responsive area, which could correspond to an ore mineral core zone with a surrounding responsive cylinder representing a pyrite halo typical of porphyry systems as defined in the Lowell - Guilbert porphyry copper model. 

 

Comments James A. Briscoe (P. Geo), the Company’s CEO, “Over the last six years we have carefully gathered across the entire Big Chunk caldera some 11 thousand geochem samples and assayed them for 64 elements each, completed low level high resolution aeromagnetics and compiled base geology. Additionally, we have completed over 100 miles of ground based IP geophysics. All of this data is in digital format and can be compared and interpreted together at the same scale. The new ZTEM data for the BCSP-South Block will be another step in our meticulous exploration process. Along with all the preceding studies, it will be used to refine and pinpoint what these mutually reinforcing data appear to show – anomalies that are characteristic of large porphyry copper mineral bodies, which may contain significant mineralization. Accurately placed drill holes to test these mutually reinforcing data will be the final step in testing for the presence of significant mineralization.”

Statements in this news release that are not historical are forward looking statements. Forward looking statements in this news release include: that in certain areas all lines will be processed for 2D inversions and 3D models will be prepared; that final interpretation will be performed to pick the best targets for subsequent drill testing; that the Big Chunk caldera of Alaska bears similar features to an ore mineral core zone with a surrounding responsive cylinder representing a pyrite halo typical of porphyry systems; anomalies that are characteristic of large porphyry copper mineral bodies, which may contain significant mineralization; and that drill holes to test these mutually reinforcing data will be the final step in testing for the presence of significant mineralization. Factors which may delay or prevent these forward-looking statements from being realized include misinterpretation of data; we may not locate or agree to terms with potential partners for their incurring of exploration costs (which is essential to us), we may not be able to get equipment or labor as we need it; we may not be able to raise sufficient funds to complete our intended exploration or carry on operations; that because we are behind in payments, our creditors could seize our assets including our mineral properties; that weather, logistical problems or hazards may prevent us from exploration; that equipment may not work as well as expected; that analysis of data may not be possible accurately and at depth; and that despite encouraging data there may be no commercially exploitable mineralization on our properties. Readers should refer to the risk disclosures outlined in the Company’s recent 10-KSB and the Company’s other periodic reports filed from time to time with the Securities and Exchange Commission.
