SRI Sparton Resources Inc

Sparton Resources Inc. (TSX VENTURE:SRI) (the "Company"), announced today that
its subsidiary company Vanspar Mining Inc. has successfully completed an
advanced metallurgical test program on representative samples from its Xiushui
County carbonaceous shale hosted vanadium prospects in Jiangxi Province, China.
The work involved comprehensive agitated acid leaching tests of fresh sample
material grading approximately 0.9% V2O5, and has resulted in average recoveries
of approximately 78% for the various tests completed. The tests produced
vanadium pentoxide products containing 98.5 to 99.3% V2O5 and these qualities
are at or above industry standards. 


More importantly the leaching process developed by VanSpar is clean, with no air
or water pollution generated by the process methodology. Due to recycling of
leaching solutions there is little or no liquid waste and all solid waste
produced meets acceptable standards as feedstock for cement manufacturing in the
Xiushui area.  


This clean technology contrasts with classic processing methods used for most
shale hosted vanadium deposits in China which use(d) a salt roast process which
produces abundant chlorine and sulphur dioxide gas emissions and effluents and
solid waste that create storage and pollution mitigation problems. 


VanSpar has applied for and received patent approval in China for one flow sheet
for its new technology and acceptance of applications for three other flow
sheets using similar leaching systems with modifications made to suit differing
mineralogy in the host vanadium formations.  


TEST PROGRAM 

The program involved over 100 individual tests on fresh material grading 0.70
-1.0 % V2O5. Samples were prepared in three size fractions and leached with
various sulphuric acid and oxidizer chemical concentrations in a water solution
at temperatures varying from 80-95deg. C. Solid liquid ratios were varied and
from 1:1 to 1:4 and agitiated leaching times varied from 2-6 hours. All tests
and analyses of primary mineralization and tailings from the tests, and the
vanadium pentoxide products were completed at in Sparton's testing laboratory in
Yunnan. Quality control and assurance quality assurance methods utilized China
national standards samples as check references. As a further QC check over 80
samples from the test batches were analyzed at the ALS Chemex international
standards certified laboratory in Guangzhou, China. The variability of analyses
for V2O5 between the two laboratories for both the reference standard samples
and the test samples were within acceptable limits (+- 3-6%).


RESULTS 

Optimization of the leaching processes tested were done within projected
commercial parameters and involved using a two stage counter current leaching
system that resulted in extraction rates averaging 78% for V2O5. Extraction
rates of over 90% were achieved using additional leaching stages but it is
believed the dual leach system will be the most economical for full scale
production. 


PATENT APPLICATIONS 

Several variations of the flowsheet were developed. 

Company President, Lee Barker stated that: "Sparton is very pleased Sparton's
international exploration, development, production and evaluation programs are
being carried out under the direct supervision of A. Lee Barker, P. Eng., P
Geol., the Company's President and CEO, who is a Qualified Person under National
Instrument 43-101.
