The approaches to assessing the availability of non-renewable mineral resources are analyzed. The result of assessing the long-term availability of gold reserves in the Krasnoyarsk Territory using the model of peak curves and cumulative availability curves is presented: firsts simulate the dynamics of annual production volumes, with access to the forecast of moments of the beginning in the production decline, seconds reflect the distribution of ranked reserves of the raw material base deposits according to the indicator of economic accessibility. It is established that it is possible to achieve a peak gold production in the Krasnoyarsk Territory in the next 10 years. By this time, the half of the explored reserves currently recorded on the State Balance Sheet will be worked out, and annual production volumes will begin to decrease. The maximum volume of gold production is projected by 2028 with an expected production level of about 124 tons of gold per year. The volume of economically available gold reserves of the Krasnoyarsk Territory, including the reserves of existing enterprises, according to the authors, is approximately 960 tons, at that there will still be enough deposits on reserve, the development of which is possible with a slight increase in a price. When the volume of reserves involved in the development reaches a progressive total of 1,150 tons, the available reserves will be exhausted.

Keywords: mineral resources, availability of deposits, depletion of reserves, peak models, cumulative curve of production, gold.
