to Mineral Reserves as development progresses on the new 3,390 level with drifting planned on the Lucho, Leyton and Michelle vein structures. My conclusion is that the 2005 Pimenton Mineral Reserve and Resource estimate uses appropriate methods and data for projecting tonnes and grades from sampling of the mining stopes, sublevels, and raises. SEAL
Ore Reserve. An updated Ore Reserve for the Project of of ore containing 2,294,000kg dysprosium and 26,375,000kg Total Rare Earth Oxide (TREO) was achieved in March 2015. The Ore Reserve is classified as 100% Probable and is reported in accordance with the JORC Code 2012.
refined and unrefined mineral resources and use two variables to calculate the royalty liability: the value of the minerals (the tax base) and a royalty percentage rate (calculated in a prescribed manner) which is applied to the base. Royalties are capped and cannot exceed 5% for refined mineral resources and 7% for unrefined mineral resources.
AUSTRALIAN GUIDELINES FOR THE ESTIMATION AND CLASSIFICATION OF COAL RESOURCES 3 Term Definition and usage Confidence Confidence in Resource classification refers to the assessment of the critical data for a coal deposit and likely variation in the .
MINERAL ORE RESERVE Case 1. (3) Multiply area found by (2) by the average thickness (found by solution of the formula) of ore in the hole, which thus transforms this smaller prism into volume. (4) Multiply this volume by specific weight of ore, which gives total tonnage of ore in minor prism.

Valuing a Mining Company using Net Present Value Here is a simple, down to earth way of describing Net Present Value (NPV) : If you could take a gold mining project, with all its gold, all its costs, and all its incomes, and process the entire thing in 30 seconds – how much would you be left with?
Selection of mining method is often vacillating and a proper coal reserve estimation could be a solution to this, where the 'University of British Columbia (UBC) Method' and 'Present Situation of ...
Mineral Deposit Value – How to Calculate the Potential Value of a Mining Project When the preliminary feasibility study of a mineral project has not been completed yet, but you do want to estimate the mineral deposit value, you can calculate the potential value of a mining project by the backoftheenvelope calculation described in this article.
The key concepts relating to the calculation of recoverable reserves for selective mining in open pit gold operations are discussed. While the general concepts are relevant to a wide range of gold ore bodies, their application is specific to particular ore bodies. The important factors contributing to the recoverable reserves are geology, mining method, dilution,...
Metal Equivalent Calculation – How to Calculate the Mineral Equivalents in Polymetallic Deposits When reading a company's press release in which they announce their mineral resources and or reserves of a polymetallic deposit, you will often see them reporting in the metal equivalents of the primary metal .
Proven and Probable mineral reserves and Measured and Indicated mineral resources are commonly misused terms. The exact definitions can be hard to find but here they are all in one place, referenced from NI 43101 and the JORC code.
The primary purpose of a NAV calculation in a preliminary feasibility study or feasibility study is to demonstrate the (positive) economics of the property's reserves. The reserves represent that portion of the measured and indicated resources that is economically mineable as demonstrated by at least a preliminary feasibility study. Companies may
