Uranium Star Corp. announce it has identified a 21 kilometre trend that hosts significant amounts of vanadium on its Three Horses Property in Madagascar. This north-south trend almost stretches the entire length of the Property. The Company has since verified the existence of a third vanadium trend located 1 kilometre to the west of the initial discovery in the northern area of the Property.
21 Kilometre Vanadium Trend Confirmed
Soil sample results from the southern mineralized zone confirm at least a 1900 metre strike length with indications that the mineralized structure continues to the north. Values of up to 2710 parts per million (ppm) vanadium have been returned in soils. A land satellite imagery study indicates that the anomalous vanadium trend can be traced over the entire 21 kilometre length of the Property. This is represented by colour-depicted alteration trends using various spectral bands.
The airborne electromagnetic (AEM) survey flown late in 2007 displays an obvious zone of low resistivity that can also be extrapolated along the entire length of the property. Within this zone, the AEM survey has defined dozens of high quality electromagnetic anomalies that are interpreted to be caused by graphite. The AEM was able to clearly penetrate through a thin laterite cap that is located over a 2.5 kilometre extent of the vanadium trend. This is located in the west central part of the Property.
Horizontal loop EM surveys on the Property have confirmed the AEM anomalies, clearly defining that the southern mineralized trend and the most eastern vanadium trend are one extensive trend that can be interpreted over a length of at least 21 kilometres.
Third Vanadium Trend Discovered
Drilling and subsequent XRF analysis of selected core samples have defined a third zone of potential mineralization located parallel to and approximately 1 kilometre west of the initial northern vanadium trend discovery announced in the Company’s news release of November 18th, 2008. The initial grab sample results from both areas, confirmed by ALS Chemex, have identified vanadium values over the detection limit of 10000 ppm, or 1.7% V(2)O(5) equivalent.
Recently acquired airborne radiometric data obtained from the Madagascar Government (using 500 metre line spacing) clearly indicates that the three vanadium trends have a coincident uranium (eU) signature. Uranium Star’s ground radiometric surveys have confirmed this anomalous radioactivity.
As with the northern area, field analysis utilizing the Innov-X Systems X-50 mobile XRF unit was conducted on core samples obtained from this target area, and has indicated the presence of significant values of vanadium. Based on the vanadium mineralization identified on the southern area through XRF analysis, there appears to be a vanadium-rich trend with a strike length greater than 1900 meters. The field results from the southern area target have also yet to be verified with assay results. Core samples have been sent for analysis to ALS Chemex’s ISO 9001:2000 and ISO 17025:2005 accredited laboratories in Vancouver, B.C, Canada.
Regional Stream Sediment Sampling Identifies Additional Vanadium Trends
Geochemical analysis by ALS Chemex has been recently received for a regional stream sediment sampling program completed earlier in the year. The analysis identifies 5 additional vanadium-rich trends over strike lengths of 5.2 km, 4.6 km, 3.5 km, 2.2 km and 2.0 km respectively. These newly identified trends have received no additional work, and indicate that vanadium mineralization is everywhere on the Three Horses Property.
The vanadium mineralization is hosted by graphitic quartzofeldspathic gneiss, some of which contains appreciable amounts of sulphides, in relatively close association with marble units. Some of the better surface exposures are gossanous. Known vanadium deposits world wide do not feature any immediate analogies. It may be that Uranium Star has discovered a new variety of vanadium deposit that has yet to be documented.
The Company is awaiting assays from its recently completed drill program, which concluded largely due to the beginning of the rainy season in Madagascar. The drill has been stored on the Property in anticipation of a more extensive exploration program, which will commence in the early Spring of 2009, commensurate with the conclusion of the rainy season. Work currently being conducted includes mineralogy to specifically identify the style of vanadium mineralization. It is anticipated that this will be followed by preliminary metallurgical work to determine what recoveries can be obtained from this unique style of vanadium deposit.
Vanadium currently trades between $10.00-$11.00 per pound (where 1% of vanadium oxide (V(2)O(5)) equals 22 pounds). It is a rare, strategic metal used for production of high-strength low-alloy (HSLA) steels and titanium alloys.
China and the USA are the largest individual consumers of vanadium, each accounting for close to 20% of the world market. World production only totals about 100,000 tons a year. Current primary producers in South Africa are all operating at full capacity.
Commercial use stems from HSLA steels offering the ability to reduce the weight and tonnage of steel required compared to ordinary low-carbon steels because of higher yield and tensile strengths.
Ferrovanadium (FeV) is an iron alloy with a high proportion of vanadium (containing anywhere from 35% to 80% percent vanadium).
Close to 90% of ferrovanadium is used in high performance steels for:
– Construction (building frames, bridges, etc.)
– Automobile and Rail tools, parts
