At the initial stage of the appraisal of resources and poorly explored reserves, it seems impossible to conduct detailed economic calculations. To this end, the authors suggest a simplified approach applying major deposit parameters, which can be substantiated more or less objectively, as input data. These parameters are the content of commercial components in ore, the volume of ore reserves, the overburden factor, and the way of mining. The paper provides the dependency graphs for the express estimate of the efficiency of gold deposit development by open mining in the Krasnoyarsk Territory. These dependences may be used for the immediate feasibility study of deposit development if there are scarce input data available.

Key words: gold production, express method, costs, efficiency, profitability index, net earnings.
