Sparton Resources has received very positive results from the initial surface sampling program completed on its Rentian Vanadium Project in Jiangxi Province. The sampling identified base metal and silver values, including up to 2% vanadium oxide.
An 1100 metre drilling program using three drill rigs is under way to test the down dip extension of the surface zones sampled. About 1.2km of the 1.6km strike length is being tested in 10-15 shallow holes to intersect the vanadium and base metal rich unit at depths of 25-75 metres. Holes are about 150 metres apart and fill in drilling is planned once the geometry of the mineralized unit is better understood.
The company’s vanadium projects are held by VanSpar Mining, a new subsidiary company that holds Sparton’s various vanadium rights and assets in China, including Rentian and the nearby Guojiaping project.
As part of its ongoing due diligence of the Rentian Mining Licence and processing plant, the company has completed a comprehensive surface sampling program as well as a review of the Rentian processing plant operating systems and infrastructure.
More than 160 grab and chip samples were taken covering most of the vanadium unit rock exposures in the 1.6sqkm licence. There are no previous records of similar sampling and no previous drilling has been done to evaluate the vanadium rich stratigraphic unit which trends across the licence. The sampling covered most of the 1.6km strike length of the vanadium rich horizon. The vanadium rich unit appears to be about 30 metres thick, strikes northwest and dips gently 10-15 degrees to the northeast.
The best continuous chip sample returned an average of 1.10% vanadium oxide across a 24 metre-wide sampled zone. Within this interval a 12 metre wide zone averaged 1.31%. The highest value in this zone was 2% over a 1 metre interval. Other samples included 0.75% over 12 metres and 0.73% over 7 metres.
The average vanadium oxide content for the entire 162 sample group including mineralized and non mineralized zones was 0.43% and about 20% of samples assayed over 1%.
Of significant interest is that significant amounts of copper, zinc and silver are associated with the vanadium mineralization. These were detected in a number of multi element and individual analyses done for the quality control program. Values of 0.92% copper, 0.53% copper, 0.42% copper and 0.05% copper with 0.53% zinc were reported.
Significant silver values were also associated with the higher grade vanadium results. These include 1 metre chip samples grading 39.9 grams/tonne silver with 1.66% vanadium oxide, 23.1 grams/tonne silver with 1.21% vanadium oxide and 18.2 grams/tonne silver with 1.20% vanadium oxide.
