Metallurgy and Petroleum (CIM) led Estimation Best Practices Committee. They are intended to assist the Qualified Person(s) (QP) in the planning, supervision, preparation and reporting of Mineral Resource and Mineral Reserve (MRMR) estimates. All MRMR estimation work from which public reporting will ensue must be designed and carried out
The main steps of a typical mining project are: data collection with drilling, logging, sampling, and assaying; geological interpretation and domaining; estimation of a long-range mineral resource model; consideration of "modifying factors" such as mining, metallurgical, and economic factors to transform the resource model to a long-range reserve model; short-range …
Typically, mineral resources estimation follows a mineral exploration, while ore reserves estimation follows rigorous technical and economic evaluations on mining factors, alongside other pertinent operational considerations . The methodology employed remains consistent for both estimations. This chapter delineates the journey from initial ...
In geospatial data interpolation, as in mapping, mineral resource estimation, modeling and numerical modeling in geosciences, kriging has been a central technique since the advent of geostatistics.
The inherent risk associated with the estimation of mineral resources and ore reserves and subsequent classification can be reduced by a strong understanding of geological and grade continuity.The ...
Our review of mineral resource estimates published since 2017 suggests that more than half of all estimation-constraining wireframes are built using grade cut-offs and are not informed by any ...
The most common approach used in the mining industry for mineral resources modeling is to estimate the grades using ordinary kriging and report the recoverable resources based on this deterministic estimated model. Mineral resources calculated with kriging are a smooth representation of the actual distribution of grades and do not provide an assessment …
Every mining project requires defining the mineral resources prior to mine design and planning. This definition is based on geological knowledge of the orebody and on sample information from an exploration drilling grid, usually with infill drilling in the areas to be extracted during the first years of the project. The first step in resources estimation is an exploratory …
Exploration of seabed polymetallic nodules identifies the Clarion Clipperton Zone and the Indian Ocean Nodule Field to be of economic interest. Mineral resource estimation is important to the owner of the resource (all of mankind; and managed by the International Seabed Authority; ISA) and to developers (commercial and government groups holding contracts with …
presents a comprehensive applied approach to the estimation of mineral resources/reserves with particular emphasis on the geological basis of such estimations, the … Introduction 1 - Springer The estimation of mineral resources is an important task for geoscientists and mining en-gineers. The approaches to this challenge have evolved over the ...
Mineral Resource Estimation The General Guidelines of the Estimation of Mineral Resources and Mineral Reserves document apply to uranium deposits. In addition, the following guidelines apply. The value of a commodity is obviously fundamental to a resource estimate. However, the price of uranium at any given time may not be known with accuracy ...
exploration results, mineral resources and mineral reserves, July 2006" (CRIRSCO) with purpose to harmonize with international praxis. The aim of this study was to quantify the Nesodden hydrothermal quartz deposit due to the results from the drilling campaign that took place autumn 2015 and the mapping carried out summer 2015.
Mineral resources are estimated to establish potential orebody with acceptable quality (grade) and quantity (tonnage) to validate investment. Estimating mineral resources is associated with uncertainty from sampling, geological heterogeneity, shortage of knowledge and application of mathematical models at sampled and unsampled locations. The uncertainty …
From the above domain categories, mineral resources and ore reserves estimation in the presence of hard boundaries is straightforward because only samples within a domain are used, and there is no ...
The Indicated Mineral resource has a higher level of confidence than Inferred Mineral Resource and thus can be used for further analysis of mine planning and assessment of economic viability of the mine project." "Inferred Mineral Resource is a subpart of the Mineral Resource in which the estimation of grade and quantity is based on the ...
We study the full life cycle of mineral commodities to inform decisions about where and how to develop mineral resources. We estimate regional, national and global mineral resources. This …

Figure 1. A cartoon showing the relationship between mineral resources and mineral reserves. The process of resource estimation is used to define a mineral resource in three dimensions, with the ultimate aim of determining both the size (typically reported in …
In mining projects, in both open-pit and underground mines, 3D modelling of the mineral deposit plays a key role that may result in both positive or negative consequences on downstream activities such as production schedules; mine design and optimization; resource estimation; grade-control classification; and ultimately, management of cash flows depending …

On any deposit delimitation program, sampling is an essential step to establish the limits, volume, mass, and grade of the mineral deposit. Thus, the main goal of sampling is to generate values about the mineralization (e.g., assays of metal grades) that are the fundamental information to be utilized in carrying out resource and/or reserve estimations.
Further, the book addresses the evaluation of mineral resources, from sampling techniques to the economic evaluation of mining projects (i.e. types and density of sampling, mean grade definition and calculation, Sichel's estimator, evaluation methods – classical and geostatistical, economic evaluation – NPV,IRR, and PP, estimation of risk ...
