Количественная оценка минеральных ресурсов платины, палладия, золота, никеля и меди в неоткрытых месторождениях PGE в основных и ультраосновных расслоенных  интрузиях в Финляндии

Most of the known platinum group element (PGE) resources in Finland are in contact- and reef-type deposits in 2.45 Ga mafic-ultramafic layered intrusions. These intrusions also have the potential to contain the majority of possibly existing, yet undiscovered, PGE resources in Finland. The undiscovered Pt, Pd, Au, Ni, and Cu resources in contact- and reef-type deposits were estimated down to one kilometre depth using the three-part quantitative assessment method.

В соответствии с решение)! коллегии Министерстве геологии CCJP от 23 ноября 1972 года (приказ Министра геологии СССР от 8 декабря 1972 года № 579) министерства и управления геологии союзных республик и организации союзного подчинения осуществляют, начиная с 1973 года, попутные поиски месторождений камнесамоцветного сырья.

This Code for the Valuation of Mineral Properties (the “CIMVAL Code”) is the result of a review more than a decade after the release in 2003 of the “Standards and Guidelines for Valuation of Mineral Properties” (the "2003 Standards"). The purpose of the review is to update the 2003 Standards to reflect domestic valuation, international valuation, and regulatory developments. The CIMVAL Code was adopted by the Canadian Institute of Mining, Metallurgy & Petroleum (the "CIM") Council on November 29, 2019. The CIMVAL Code supersedes the 2003 Standards. <...>

Коллегия Министерства геологии СССР решением от 23 ноября 1972 г. (приказ Министра геологии СССР от 8 декабря 1972 г., № 579) в целях расширения минерально-сырьевой базы ювелирной и камнерезной промышленности обязала министерства и управления геологии союзных республик осуществлять, начиная о 1973 года, попутные поиски месторождений ювелирных (драгоценных и полудрагоценных), поделочных и декоративно-облицовочных камней при проведении геологической съемки и геологоразведочных работ на другие полезные ископаемые.

Through the years, geologists, mining engineers, and others operating in the minerals field have used various terms to describe and classify mineral resources, which as defined herein include energy materials. Some of these terms have gained wide use and acceptance, although they are not always used with precisely the same meaning.

The U.S. Geological Survey (USGS) collects information about the quantity and quality of all mineral resources. In 1976, the USGS and the U.S. Bureau of Mines developed a common classification and nomenclature, which was published as USGS Bulletin 1450-A—“Principles of the Mineral Resource Classification System of the U.S. Bureau of Mines and U.S. Geological Survey.” Experience with this resource classification system showed that some changes were necessary in order to make it more workable in practice and more useful in long-term planning. Therefore, representatives of the USGS and the U.S. Bureau of Mines collaborated to revise Bulletin 1450-A. Their work was published in 1980 as USGS Circular 831— “Principles of a Resource/Reserve Classification for Minerals. <...>

In contrast to the recognized man/machine system of industry, the production process of mineral resources brings about a man/machine/nature system. The dynamic evolution of this system is characterized by a steady increase in the level of human labour. This also means that labour becomes increasingly complex and complicated due to the interaction with increased automation and mechanization.

The International Template for Reporting of Exploration Results, Mineral Resources and Mineral Reserves integrates the minimum standards being adopted in national reporting codes worldwide with recommendations and interpretive guidelines for the Public Reporting of Exploration Results, Mineral Resources and Mineral Reserves. The definitions in this edition of the International Reporting Template are either identical to, or not materially different from those definitions used in the countries represented on the CRIRSCO committee <...>
