The article is devoted to the analysis of the possibilities of increasing the efficiency of a mining company by managing specific assets using a complementary approach. The relevance of the work is caused by the fact that the mining industry differs from other sectors of the economy because of the specificity of the mineral raw materials and production processes. The mineral resources assets that form the company’s mineral resources potential are unique in nature. Their main feature is the depletion and dependence of the value of mineral raw materials on the influence of a combination of factors, whose action can cause both its decrease and increase. In addition, the specifics of the mining processes determine the organization of activities, complicating the management of a mining enterprise, which, along with constantly changing external factors, forces the management of a mining company to look for new ways to improve production efficiency. The purpose of the study is to establish the role of digital assets in the activities of mining enterprises and determine the necessary requirements for their successful operation. In the course of the study, an analysis of Russian and foreign scientific literature was carried out, the experience of mining enterprises was studied, and methods such as comparative analysis, systematization and generalization of the results were used. The article discusses the growing importance of digitalization for mining enterprises. The problems of introducing digital assets in the mining industry have been identified. The authors substantiated the need for complex integration of digital assets with other assets, and identified the relationships between them. The concept of complementarity in the analysis of intangible assets is disclosed and the characteristics of complementary assets are clarified. It was revealed that it is the complementary assets that contribute to improving the efficiency of mining companies through the development of open innovations, provided that the necessary environment is created. The significance of this study is that it will allow the management of mining companies to make adjustments to the organization of production and management processes in order to increase their economic efficiency. The directions of further research are the presentation of a model for the integration of complementary assets and the development of a methodology for assessing the complex economic effects of the use of complementary assets in mining companies.
