Songun copper ore is the most famous copper ore in Iran that exploration operation has started since 1368 and 156 bore holes has drilled until now.This mine has located in 30 km from Tabriz. At first for determining final pit limit by cross sectional (wire frame) model and blocking with dimensions 25ײ5ױ2.5 has used Minex software. For preparing economic blocking model and determining final pit has used from Pitwin32 optimization software. For analyzing final results of mine designing for pure copper has considered different price such as 1600,1800,2000 $/ton. For three price has considered one by one 0.25,0.29,0.33 percent cut-off grade. final pit determined by using Floating cone&Lerchs-Grossmann three dimention methods for above prices. Studies shows that first by incresing price of copper number of blocks in ore of mine gets more and the result of it increse value of open pit. Second the value of open pit that gets from LG method is the most of the value of open pit gets from FC method in three state.
