   Geology
   Several major regional shear zones which can be traced for hundreds of kilometres appear to be the major control on gold mineralization in the Akbakai area. Gold mineralization occurs both along the major regional structures and along subsidiary secondary features in complex areas around granite intrusions. These structural features can be traced into the Steppe Gold licence. There are numerous known gold deposits in the licence; however, gold exploration in the belt has focused on the Akbakai region to the north. Steppe Gold has already identified several mineralized target areas within the licence which have a similar structural and geological setting to Akbakai.

    Mining
   As is commonin many gold processing operations, cyanide is used to leach gold from the ore at Akbakai mine facilities. Prior to implementation of this EcoLinks funded project, about 20-30% more cyanide was being used at Akbakai mine facilities as compared to similarprocessing facilities world-wide. Furthermore, gold extraction resulting from cyanide leaching at Akbakai was about 15% lower than at other facilities.
   Capitalcosts for construction of a cyanide recovery plant at Akbakai are estimated at $200,000. Cash flow costs for this plant show a positive income of approximately $60,000 annually (avoided cyanide purchase costs). Thus, the simple pay back period of a cyanide recovery plant is about 3.3 years.
