   Feasibility study of Cheshmeh Zard-e Arghash gold deposit

   Abstract
   The Cheshmeh Zard gold deposit is one of several gold anomalies in the Arghash Gold Project that is located 45 Km away from southwest of Neyshabour. For prefeasibility study, after exploration in the area, preparation of topography and geology maps, and sample analysis, the modeling of deposit was led to first estimation of ore reserve. The estimated reserve of deposit is about 138000 tons ore with 376 ppm gold grade. Through geomechanical assessment and determining the geometrical parameters of the deposit, the open-pit mining was identified as the appropriate extraction method for the oxide zone of deposit. By selecting the loading and transportation machines, the final ration of waste to ore is 8 to 1.
   For estimation of costs of processing plant including crushing and smelting machines, designation of leaching pools, and primary exploitation of gold, the total cost of project was estimated. Considering the high proportion of processing costs, several suggestions were made for complementary studies.
   It should be noted that estimations made in this report are based on the drilling data achieved from northeastern portion of the deposit, so for final estimation of costs, the data of southwestern portion of the deposit should be added to previous data. It seems that the greater reserve in the oxide zone than the sulfide zone can cause the lesser processing costs. This study was conducted for a type of gold deposit, of which there are several other cases in Iran.
