CLASSICAL METHODS OF ORE RESERVE ESTIMATION - Basic .Mar 2, 2016 . As discussed in my previous post, the main objective of ore reserve estimation is to as accurately as possible define the extent (size) and value (grade) of a mineral deposit. We are confronted with two primary objective in this process and these are: Extent Determination and; Value Determination. Value and.calculation of reserves mining,Mineral Deposit Value - How to Calculate the Potential Value of a .Therefore you could see a major or mid-tier mining company that wants to replace their mined reserves just pay a small percentage of this metal value for the deposit (i.e. 5% to 10%). To find out how much of this mineral deposit value I assign to the mining company's value as a whole, I recommend you to read the second.

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.
In mines situated in rugged mountainous districts and explored through shaft openings it may sometimes be desirable, for operating purposes, to drive a long adit to replace the shaft as the main extraction opening to eliminate high pumping and hoisting charges or to provide the most.

Ore is defined as a mineral or mineral aggregate more or less mixed with a gangue, from which a metal or metals can be won at a profit or in the hopes of a profit.* From this definition it follows.

Mineral reserves and mineral resources estimates contained in this annual Report have been calculated as at 31 December 2016 in accordance with National Instrument 43-101 as required by Canadian securities regulatory authorities, unless otherwise stated. Canadian. Institute of Mining, Metallurgy and Petroleum ('CIM').
Geologists and mining engineers advocate that the grade of a mineral deposit depends on the location of subblock within the orebody and the sample value of the small block. Thus, conventional methods of resource and reserve estimation [polygonal, triangular, rectangular, cross- and longitudinal sections, level plan and.
Only Measured and Indicated Mineral Resources can be converted to Ore Reserves. The figures included in our Mineral Resources and Ore Reserves statement are estimates only and not precise calculations, therefore appropriate rounding according to JORC guidelines has been applied. The Mineral Resource and Ore.
May 10, 2017 . In recent years, the introduction of specific software for the evaluation of geological resources and mineral reserves has increased significantly thanks to the use of block models capable of working with large databases and applicable to virtually all types of deposits. It is only in layered, tabular-shaped.
Notes for Fire Creek Underground Reserves: Reserves have been estimated using a gold price of US$1,200/ounce and a silver price of US$17.00/ounce. Metallurgical recoveries for gold and silver are 93% and 88% respectively. Gold equivalent ounces were calculated based on one ounce of gold being equivalent to.
Abstract. Mineral Resources and their subsequent conversion to Ore Reserves are of key importance to mining companies. Their reliable estimation is critical to both the confidence in a feasibility study, and also to the day-to-day operation of a mine. Together with sampling, assaying, geological and other errors introduced.

to develop or update a mine plan resulting in a consistent quality coal feed. CONDITIONAL MINING SIMULATIONS. Conditional mining simulations are computerized simulations that virtually mine the coal reserve. Calculating block- by-block based on the anticipated mine plan, simulations not only determine the.
Mineral Reserves have been calculated using metal prices of US$2.75/lb copper, US$1.00/lb zinc, US$1.00/lb lead, US$8.00/lb nickel, US$1,000/oz gold and exchange rates of EUR/US$ 1.25, US$/SEK 7.00 and Chilean Peso/US$ 550. Candelaria and Ojos Open pit Mineral Resources are reported within a conceptual pit.

Planned production with currently known ore-reserves is about 7 years. The Reviewed Mineral Reserves of Silver Mine : Ore-reserve estimate follows the Australian JORC Code. The calculations are done with a "net smelter return cut-off" at 30 €/ton ore for underground-mining and 60 €/ton for ore-feed to the mill.
