Mineral Resource Estimation, Mineral Reserve Estimation & Geological Modelling 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 ...
The 2014 Mineral Resource model was compared with the updated Mineral Resource model (2015) within a common volume i.e. within the Business Plan (BP) 2015 $1,600 Mineral Resource shell and the $1,200 Mineral Reserve design (below the topography as no mining has taken place at FE2) to quantify if the Oxide Ore potential had increased as a result ...
Gadir Underground Mine – JORC (2012) Mineral Resources and Ore Reserves Statements at 30 June 2020. Anglo Asian, together with the mining and geological consulting group Mining Plus, prepared the Mineral Resources and Ore Reserves estimation of the Gadir deposit.
The Mineral Resource used as the basis for the Ore Reserve estimate was announced to market on 5th August 2019 (see Attachment C). Indicated Resources have been converted to Probable Ore Reserves subject to mine design physicals and an economic evaluation. No Measured material was contained in the Resource.
Upon completion of the Mineral Resource estimates, SRK commenced a work program to develop mine plans and Ore Reserve estimates to support the FEL3 Project study. The study focused on a base case scenario that entailed the extraction of Export Ore …

of mineral and energy-fuel resources for the Na tion or for specific areas. RESOURCE/RESERVE DEFINITIONS A dictionary definition of resource, "something in reserve or ready if needed," has been adapted for mineral and energy resources to comprise all materials, including those only surmised to exist, that have present or anticipated future value.
Estimation of Mineral Resources is often a team effort (for example, involving one person or team collecting the data and another person or team preparing the Mineral Resource estimate). Within this team, geologists usually occupy the pivotal role. Estimation of Ore Reserves is almost always a team effort involving a number of technical

In making ore-reserve estimates as a basis for valuing a property for sale or other purpose, most engineers, to avoid overvaluation and at the same time recognize potentialities for ore as yet undisclosed, estimate tonnages under three separate headings: "Developed ore" (sometimes termed "positive ore"), "probable ore," and ...
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.

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 ...
Workers in the field of mineral resource and ore reserve estimation (Davis, 1971) corrected this shortcoming by borrowing techniques from formal statistical theory. These include analysis of sample population, range, frequency distribution, histogram plot, mean, variance, standard deviation, correlation coefficients, analysis of variances, t ...
The information in this report that relates to AF Gap Mineral Resources and Ore Reserve estimate was first reported by the Company in a …
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
Exploration Results, Mineral Resources and Ore Reserves, 2012 Edition (JORC Code), and the ASX Listing Rules and provides a summary of pertinent information and JORC Code Table 1 attachments to support the updated Mineral Resources Estimates on a domain basis
The simple yet accurate ore reserve estimation technique used is classical methods. Classical methods employ simple geometric function and rules that are easily applied to simple uncomplicated orebodies. In the following example, we will be working through the classical methods in determining the tonnage and grade of the Minetechpg Copper Deposit.
AngloGold Ashanti strives to actively create value by growing its major assets – the Mineral Resource and Ore Reserve. This drive is based on active, well-defined brownfields and greenfields exploration programmes, innovation in both geological modelling and mine planning, and continual optimisation of the asset portfolio. Ensuring a viable Mineral Resource and Ore Reserve …
Mineral Reserves is the responsibility of the company acting through its Board of Directors. Any such report must be based on and fairly reflect a Mineral Resource and/or Mineral Reserve estimate and supporting documentation prepared by a Competent Person. A company making a Public Report shall disclose the name of the
mineral resource estimation RSC consultants take great pride in providing clients with high-quality resource estimations, which are fit for purpose. Engage us to provide thorough estimations to use in resource reporting, listings or other important documents.
Notes: Total estimates are rounded to reflect confidence and resource classification. Classification of Mineral Resources incorporates the terms and defination from the Australiasian Code for Reporting and Exploration Results, Mineral Resources and Ore Reserves (JORC Code, 2012) published by the Joint Ore Reserve Committee (JORC).
Mineral resource estimation is used to determine and define the ore tonnage and grade of a geological deposit, from the developed block model. There are different estimation methods used for different scenarios dependent upon the ore boundaries, geological deposit geometry, grade variability and the amount of time and money available.
At NM 's request, Optiro Pty Ltd (Optiro) has updated the Mineral Resource estimate for the Sokor Project and has incorporated data from 24 diamond holes drilled by CNMC during 2018, since NM's 31 December 2017 Mineral Resource and Ore Reserve Statement. Mineral Resources have been

3.2.3: Overview of Reserve Estimation Methods. The polygon method is an old and established approach based on a simple geometric algorithm, in which we construct a polygon around each hole to determine an area of influence for that hole; and then the total volume directly beneath the polygon is assigned the same values as the drill hole from which we constructed the polygon.
