The Gold Jackpot agreement enables the Company to explore and potentially mine a concession situated near both lucrative producing mines and industry leaders. The existing data on the Gold Jackpot prospect is extremely encouraging because of the high-grade nature of the gold-silver-tellurium mineralization present.

As Chairman of Spartan, I look forward to develop Spartan's Nevada properties for the benefit of Sphere and all shareholders".

Gold Jackpot Gold Property

The Gold Jackpot property is located 70 kilometers north of the Long Canyon, Nevada gold property of Fronteer Gold/Newmont, along the northern extension of the Pequop Gold Trend in the northeastern part of Elko County. The Gold Jackpot property comprises non-contiguous blocks containing 124 unpatented lode mining claims, covering approximately 2,480 acres, along a 6 Km long system length. The exploration focus at Gold Jackpot will be on high-grade epithermal Emperor Mine (Vatakuolo) style gold-silver-tellurium mineralization exposed at the surface, as well as indications of Carlin-style gold mineralization and possible hidden porphyry copper-gold mineralization at depth. Gold Jackpot is in the vicinity of the large Long Canyon/West Pequop (Fronteer Gold/Newmont/AgnicoEagle) gold properties and east of the Jerritt Canyon gold mine (Yukon-Nevada Gold Corp.). The previous geophysical, structural, and geological interpretations of Gold Jackpot indicate that the property has favourable characteristics for the above styles of gold mineralization. Tenneco Minerals drilled at least 3 exploration holes on the Gold Jackpot property 1989-1990. Mexivada began a program of geologic mapping the property in 2010, which will be completed in 2011, along with a program of geophysics to aid in delineation of the gold targets present. Additional drilling work is planned at Gold Jackpot by the Company under a two-phase exploration program. The exploration goal at the Gold Jackpot prospect is to identify an open-pittable and underground-mineable gold-silver-tellurium resource. Tellurium is used in the production of thin-film solar panel chips by such companies as First Solar Corporation.
