The mineral resources and ore reserves of a mineral deposit are estimated basically by one straightforward formula with small variations as and when they arise.
The document discusses methods for estimating mineral reserves, specifically focusing on the triangular method. It defines mineral reserves and describes proven and probable reserves.
However, the conversion of Mineral Resources to Ore Reserves remains a difficult and subjective process and a consistent approach to convert Mineral Resources to Ore Reserves as part of the cave flow modelling process is not published in the literature.
The AusIMM is to be congratulated on the excellent result of some five years of collating a series of 79 papers covering, in 9 chapters, the whole spectrum of ore resource and …

Review(s) of: Mineral resource and ore reserve estimation - the AusIMM guide to good practice, second edition, (Monograph 30)
3.2.3: Overview of Reserve Estimation Methods. ... Geostatistical methods employed for ore reserve estimation utilize three-dimensional spatial statistics to improve the quality of the estimate. Classical statistics requires use of a particular distribution model, e.g., the data are normally distributed, and that the samples be independent of ...
The estimation of Mineral Resources and Ore Reserves is a team effort in which the geologist is arguably the essen-tial component, responsible for the resource model, which underlies the entire process. Finance providers worldwide require transparent and regulated reporting policies to understand the resource/reserve base, and to minimize
Mineral resource estimation has changed considerably in the past 25 years: geostatistical techniques have become commonplace and continue to evolve; computational horsepower has revolutionized all facets of numerical modeling; mining and processing operations are often larger; and uncertainty quantification is becoming standard practice.
In mining, ore resource and reserve estimation is used to determine both the quantity and quality of an ore deposit, also called tonnage and estimated economic value. It can be performed initially to assess mineral resources, but also along the mining process to calculate the remaining ore reserves. Different parts of a deposit may contain ...
Errors and Uncertainty in Mineral Resource and Ore Reserve Estimation: The Importance of Getting it Right SIMON C. DOMINY; SIMON C. DOMINY Economic Geology Research Unit, School of Earth Sciences, James Cook University, Townsville, Queensland, Australia.
It is the general term for mineral resources and ore reserves. ... Therefore, when estimating the mineral resources and reserves in the stage of mining rights assessment, the estimated resources should be utilized according to the reliability coefficient of 0.5–0.8. In the feasibility or pre-feasibility study and mine design, the …
1 Guidelines for Resource and Reserve Estimation for Brines Mineral-enriched brines contain valuable elements in solution that may be economically recovered.
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 tonnes) and grade (generally expressed as the metal or mineralcontent in wt. % or g/t ...
