It ranges between searching for a new mineral prospect (reconnaissance) and evaluation of the property for economic mining (feasibility study). It also includes augmentation of additional ore reserves and resources in the mine and total mining district. Various exploration techniques have been followed over the centuries. Exploration is conducted by one or a combination of multiple available
Evaluation of Mineral Deposits Evaluation of Mineral Deposits When is a prospect a mine? Factors that work together to make a mineral deposit "economic" (ie profit-making) : current and future selling prices are forecast to remain the same or increase
2013-06-25· The terminology used to define mineral assets is divided into 2 major groups: Resources and Reserves. Figure 1. Resources and Reserves: The relationships between the five groups of mineral asset reporting. Mineral Resources. A Resource is a concentration of a minerals that has a reasonable prospect of economic extraction. Its location, grade
Mineral resource classification is the classification of mineral resources based on an increasing level of geological knowledge and confidence. Mineral deposits can be classified as: Mineral resources that are potentially valuable, and for which reasonable prospects exist for eventual economic extraction.; Mineral reserves or Ore reserves are valuable and legally, economically, and technically
2003-11-23· In reporting, a Mineral Resource must meet the minimum requirement of “reasonable prospects for economic extraction”. This will require the concurrent collection and storage of preliminary economic, mining, metallurgical, environmental, legal and social data and other information for use in the estimation of MRMR.

2016-09-01· The CIM Definition Standards on Mineral Resources and Reserves introduced definitions and guidance for the public disclosure of mineral resources and mineral reserves and mining studies used in Canada by Canadian public reporting mining companies, whether their deposits are in Canada or elsewhere in the world. They were adopted by the Canadian
unsustainable industry, where eventually the extraction rate will exhaust the entire economic mineral reserves. This type of long-term investments is considered risky, but if analyzed from the point of view of planning, high risk is really in the stages of prospecting and exploration.
Mineral Reserves are sub-divided in order of increasing confidence into Probable Mineral Reserves and Proven Mineral Reserves. Mineral Reserves are those parts of Mineral Resources which, after the application of all mining factors, are the basis of an economically viable project after taking account of all relevant processing, metallurgical, economic, marketing, legal, environment, socio
Mineral Reserves. A Mineral Reserve is the economically mineable part of a Measured or Indicated Mineral Resource demonstrated by at least a Preliminary Feasibility Study. This Study must include adequate information on mining, processing, metallurgical, economic and other relevant factors that demonstrate, at the time of reporting, that

China Mineral Resources 2015 Chapter II Status of Mineral Resources In 2014, evident growths have been witnessed in the newly-discovered reserves & resources of major minerals such as coal, oil, natural gas, shale gas, manganese ore, bauxite, gold, tungsten, molybdenum and so on. The geological reserves of shale gas were reported for the first
Purpose of the Seminar. The seminar is intended for participants with responsibilities for mineral exploration. Project geologists, exploration managers, corporate planners, and government policy analysts will find it to be a useful opportunity to study, learn and utilize economic evaluation principles as applied to support exploration and acquisition decisions.
means ore of metal and every natural substance that can be mined and that is either loose, or found in fragmentary or broken rock that is not talus rock and occurs in loose earth, gravel and sand, and includes rock or other materials from placer mine tailings, dumps and previously mined deposits of placer minerals, but does not include a mineral substance or the substances described in
Mineral economics. South Africa has an abundance of mineral resources, accounting for a significant proportion of world production and reserves, and South African mining companies are key players in the global industry. As a global player, it is important that the industry is well positioned as an investment destination through policies that
The second part concerns sampling, documentation and computation of ore reserves and economic assessment of mineral deposits. This new edition has been very extensively revised and brought up to date. This holds true particularly for the chapters on geochemical and geophysical methods, the use of photo-geology and satellite imagery, oil and gas prospecting, exploration of underwater minerals
From the CIM Standards on Mineral Resources and Reserves (2000): A Mineral Resource is a concentration or occurrence of natural, solid, inorganic, or fossilized organic material in or on the Earth’s crust in such form and quantity and of such a grade or quality that it has reasonable prospects for economic extraction.
