Problems associated with effective diamond exploration


, : Problems associated with effective diamond exploration. Mineral'nyye Resursy Rossii(Ekonomika i Upravleniye 2006(3): 32-38

The analysis of data on production history, additions to and withdrawal of reserves, the structure of hypothetical diamond resources in the Russian Federation (RF) over the last decade shows an obvious development and intensification of number of negative tendencies. They are caused by a considerable decline in open pit reserves and increase in shaft mining, as well as an acute shortage of hypothetical resources under P (sub 2) category with reserves under P (sub 3) category estimated as rather large. The existing situation arises from a very low prospecting effectiveness. Despite considerable appropriations, prospecting has not been producing positive economic results for over 10 years. The main reasons of the failure to discover new prospects are on the one hand conditions of prospecting for new targets that have substantially complicated in recent years and the morally obsolete prospecting technology, the cost-is-no object approach to financing of prospecting, and monopolization of practically all prospecting work in the country by one large company, ALROSA JSC, on the other. The main tasks that should be solved to forward the federal interests are as follows: (1) the advance predictive mineragenetic investigation of new territories (the Murmansk Oblast, Republic of Karelia, central regions of the RF European part, Irkutsk Oblast, and the Evenk Autonomous Okrug) aimed at detecting diamond areas and fields to create alternative resource bases in the future; (2) the localization of detected hypothetical resources to prepare them for the conversion into reserves by 2010; (3) the development of new effective in-depth prospecting technologies.
