Exploration projects need considerable investments. These projects are associated with high techno-economical risks. Therefore, Evaluation of exploration potential is necessary. It is determined in primary stages of exploration whether the deposit reserve is not economic or the grade is less than normal grade, and it may be decided to stop the project. The minimum acceptable target reserve is known as a criterion for determining the economic potential of deposit regarding to techno-economical environment of project. In this research a new model is proposed for determining minimum acceptable target reserves in gold projects. This model is verified through the economic filed data from Zarshpran gold mine. The graph of grade versus tonnage and internal rate of return versus tonnage are demon stared through Excel software. The results of this research could be used as powerful decision making tools in gold exploration projects.
