A model for assessing the efficiency of material and manpower resources involved in gold mining operations is proposed. The productivity growth is calculated using the authors’ method of aggregate assessment of operating expenses in the context of limited availability of information on the parameters (specific complexities) of a deposit. Specifically, the proposed model allows for disaggregating and estimating the input of the natural resource quality degradation over time (i.e. depletion-driven natural variation in the metal content and chemical composition of the ore input) to the multifactor productivity (MFP). The approach was tested in the course of open-pit mining at gold mines in the Krasnoyarsk Krai. It is established that a 20% decline in total factor (multifactor) productivity over the past six years of mining operations has been caused by a fall in gold content (grade) of ore. Introducing technological advancements will help to mitigate the negative impact of the depletion of developed gold reserves as long as it ensures time-variable reduction of at least 1.14% per year in operational costs.

Keywords: mineral resources, multifactor productivity, resource depletion, expenses, gold, Krasnoyarsk Krai.
