GEOSTATISTICAL ORE RESERVE ESTIMATION ~ GeologyHub

Feb 25, 2015  The development of geostatistics as an ore reserve estimation methodology emerged in France in early 1960 from the work of Matheron (1962) and was based on original studies by D.G. Krige functioning the optimal assigning of weights to the neighbouring sample values used in estimating the grade of blocks in South African gold mines.

Methodologies in the valuation of mineral rights

important parameters in the consideration of any gold-hosting deposit. They are the chief elements dictating costs and revenue in gold mines and provide the basis for the assessment of fair value for mineral property transactions. These parameters may be modified from time to time, although the tendency is to rather adjust the comparative The ...

The prime objective of mineral exploration is to find and acquire a maximum number of such economic mineral deposits at a minimum cost and within minimum time.Mineral exploration acceleration is due to (1) increasing demand for metals that were not sought earlier, (2) growth of industrial output, (3) new ore types, and (4) greatly improved ...

Evaluation of Mineral Deposits

The estimated grade and quantity of ore in the ground is usually referred to as the geological reserve. But, since the total amount of ore present can be quite different from that which is extractable at a profit, a mining reserve is calculated which allows for economic conditions, limitations of the mining method and dilution of the mineral by ...
