The CIM Estimation of Mineral Resources and Mineral Reserves Best Practice Guidelines (MRMR Best Practice Guidelines) were prepared by the Canadian Institute of Mining, Metallurgy and Petroleum's (CIM) Mineral Resources and Mineral Reserves Committee (CIM MRMR Committee) to update an earlier version that was accepted by CIM Council on November 23, 2003 (CIM, 2003). These 2019 MRMR Best Practice Guidelines supersede and replace the November 23, 2003 version of the MRMR Guidelines <...>

This manual provides a reference for geologists and engineers attending Snowden’s Advanced Resource Estimation course. The purpose of this course is to skill geologists and mining engineers with the tools to carry out advanced resource estimation techniques.

This book is about resource modeling. It explains important issues; it describes geological and statistical tools used in resource modeling; and presents case studies for illustration. The main intent is to avoid strict theoretical presentations, and focus on practical adaptations that result in good resource estimation practice.

Russia has increasingly become one of the most important centres for the activities on raw commodity assessments in the recent years due to its enormous resources spread out over a huge territory. As Russia is rapidly closing the gap between the requirements of the internationally accepted codes and its own resource assessment standard, the practical reality is that the legacy of the Soviet Union for the assessment of resources is still active and alive today. However, this does not mean the requirements of the old Soviet system, now the Russian system, are redundant or unacceptable to the codes seen in the international scenery; but it is rather a descriptive and useful tool which guides the competent persons and practitioners in a well prescribed way when they are assessing the mineral resources in Russia. As the old Soviet standard has also been adopted into the national legislations in the other former Soviet Union countries similar to the current Russian system, the Russian code has become an important element in reconciliation of the resources in accordance with the criteria defined in the internationally recognised codes for Reporting Mineral Resources and Ore Reserves such as JORC. This article reviews the experience of IMC in resource estimation in both Russia and neighbouring CIS countries in compliance with both the national code and international codes, and the related issues and obstacles faced and dealt by the competent persons <...>

Earth sciences data are typically distributed in space and/or in time. Knowledge of an attribute value, say, a mineral grade or a pollutant concentration, is thus of little interest unless location and/or time of measurement are known and accounted for in the data analysis. Geostatistics provides a set of statistical tools for incorporating the spatial and temporal coordinates of observations in data processing.

Изложены научно-методические основы оценки прогнозных ресурсов твердых полезных ископаемых. Приведена система единиц учета количества минерального сырья в недрах, увязанная со стадийностью ГРР и объектами оценки. Рассматриваются вопросы металлогенического районирования и типизации рудоносных объектов, а также проблема создания их моделей. Дается обзор методов оценки прогнозных ресурсов, в том числе ограниченно используемых, но перспективных. Рассмотрены особенности использования и рационального комплексирования методов оценки применительно к рудоносным объектам различного иерархического уровня. Приведен порядок оценки, апробации и учета прогнозных ресурсов.
Предложена методика стоимостной оценки запасов и прогнозных ресурсов.

Gold, a chemical element with the symbol Au, is a highly sought-after precious metal, having been used as money, in jewelry, in sculpture, and for ornamentation since the beginning of recorded history. The metal occurs as nuggets or grains in rocks, in veins and in alluvial deposits. Gold mining consists of the processes and techniques employed in the removal of gold from the ground. There are several techniques by which gold may be extracted from the Earth. Since the 1880s, South Africa has been the source for a large proportion of the world’s gold supply, with about 50% of all gold ever produced having come from South Africa. Other major producers are the United States, Australia, China, Russia and Peru. The world's oceans also hold a vast amount of gold, but in very low concentrations. At current consumption rates, the supply of gold is believed to last 45 years. This book will present current research on gold mining including methodologies for discovering new deposits of gold as well as economic and environmental issues. <...>

В книге изложен новый метод количественной оценки прогнозных ресурсов полезных ископаемых по результатам литохимического опробования. Метод основан на использовании параметров подсчета запасов, принятых при разведке месторождений: минимального промышленного содержания, минимального объема руды, коэффициента рудоносности. Приведены примеры вычисления ресурсов на разных стадиях геологоразведочных работ.

Для специалистов, занимающихся поисками и разведкой месторождений,  студентов и аспирантов геологических вузов.
