Ziggurat Gold Property

The Ziggurat gold property is located approximately 20 kilometers north of Round Mountain, Nevada and comprises one contiguous block containing 57 unpatented lode mining claims, covering approximately 1,140 acres. All of the claims are within the Round Mountain-Northumberland Mining District in Nye County. The property has a National Instrument (NI) 43-101 technical report prepared by a Competent Person. According to the NI 43-101 technical report, the exploration focus at Ziggurat will be on Carlin-type mineralization, which typically occurs as finely dispersed sub-micron gold and some silver. The properties are in the vicinity of the large Round Mountain (Kinross-Barrick), Gold Hill (Kinross-Barrick), and Northumberland (Fronteer Gold) gold mines. The previous geophysical and geological interpretations indicate that the Ziggurat property has favorable characteristics for potentially open pittable Carlin-style gold mineralization.

Additional drilling, geophysical and geological work is planned under a two-phase exploration program. Since the property is situated adjacent to other current gold mining properties such as Northumberland, Gold Hill, and Round Mountain, and the geologic structure and surface-mineralized host rocks appear very favorable, the Ziggurat property justifies additional exploration expenditure.

The exploration goal at the Ziggurat prospect is to identify a plus 1,000,000 ounce open-pittable gold mining resource. Major mining projects are currently operated by Barrick Gold Corporation (trading on the NYSE and the TSX) and Fronteer Gold (trading on the ASE) which exist both south and north of the Ziggurat prospect, respectively.

Malcolm Stevens, Executive Chairman and President of Sphere commented, "The Ziggurat agreement is a quantum leap for the Company in Nevada and underscores the strategy set by the Board to become a major explorer for gold in the two richest gold camps in North America. The success in implementing the Company's strategy has been the identification of appropriate partners who have the desire to locate major gold resources in Nevada. Having two projects in the same gold province allows economies of scale while enhancing the opportunity for gold discovery."

Bill Whitmore, the President of Spartan Gold Ltd. said, "Spartan Gold, is pleased to add another stellar project to the list of completed acquisitions in Nevada. We have great partners in this prospect with Sphere Resources and Mexivada". He continued, "We all recognize the potential of working a region with some of the largest gold mining companies operating productive projects right in the neighborhood. We all look forward to working in a collective manner to locate sufficient gold targets to bring this property to an operational drill ready status as quickly as possible".

Mr. Richard Redfern, CEO and President of Mexivada stated: "We are extremely pleased to be pursuing the historic and prolific Round Mountain-Northumberland gold trend with an extremely talented technical team working on the Property. We feel very confident in Spartan Gold's ability to explore and prepare the Ziggurat property to drill ready status and to have Sphere Resources guiding the completion of required formal studies to validate the prospect".
