Stina believes that the Bisoni McKay Property is an outstanding opportunity with several attractive advantages over other vanadium exploration programs:
Large, open pit mineralization target on the Northern Section A. NI 43-101 Resource Estimates show Indicatd resources of 10.6 M st at average grade of 0.39% at a cutoff
grade of 0.2% (subsection 700 feet X 100 feet).
Potentially over 30 M st of mineralization on Northern Section A.
Exploration, mining and recovery anticipated to be lower cost as the soft host rock makes drilling and mining easier, and the ore may be amenable to lower cost leaching.
Resulting capital and operating costs are anticipated to be lower.
Strategically located for easy access to the United States market, with readily available infrastructure support from the mining town of Eureka, Nevada.
Once the resources are verified to NI 43-101 Proven Resource standards and Prelimary Assessment is completed , the Company believes that it will take a very short time to complete
permitting, due diligence, and to set up a vanadium processing plant. Stina estimates capital costs of between $30 and $50 million will be needed to get to production. In addition
to producing vanadium pentoxide, Stina will consider onsite smelting to produce and market ferrovanadium.
Stina has planned an additional $1.5million CAD exploration program of Bisoni McKay Property including the Northern Area A and the Southern Area C to further test the Property
potential by drilling (both core and reverse circulation), sampling and assaying, conducting metallurgical testing, engineering and geological studies, additional staking and a scoping
study. Infill drilling within the Northern Area A will be conducted on 105 foot centres over 2,000 feet of strike length to a dept of 600 feet below surface. The combination of proposed
core and reverse circulation drilling on Northern Area A is designed to provide sufficient data for definition of a NI 43-101 compliant resource.
Potential Processing
Several metallurgical tests have been conducted over the years on ore recovered from the adjacent Gibillini property, including roasting, high temperature acid leaching and heap leaching.
Different leach methods used to extract vanadium include strong alkali and strong acid solutions as well as a salt roast water leach.
Preliminary metallurgical testing at Hazen Research in Colorado on samples taken from the Bisoni McKay property, indicated strong recovery results, including over 90% on certain tests
incorporating an acid pug/ leach system on oxidized material.
2007 Drilling
Stina has recently drilled a further 12 reverse circulation holes on Northern Section "A" just above the 2005 diamond drill core fence. The 12 holes, along with previous 2005 reverse
circulation drilling, have boxed a grid that Stina is currently attempting to qualify as indicated reserves under National Instrument 43-101. Results from each of these recent drill
holes showed very positive grades at very substantial intervals.
