Rock Soil SamplingThe Key To Most Exploration
The sample is sieved on-site using a 80 mesh sieve 178 micrometres using a stack of sieves with progressively finer mesh sizes. This ensures that the finer clay and silt size particles are concentrated as this is the particle size range which contains the highest concentration of common indicator elements such as copper lead zinc and arsenic.

Mineral Deposit ValueHow to Calculate the Potential
As you can see in the example above the deposit does not have to be enormous in size (only 500 meters long by 100 meters wide) to contain a valuable deposit (approximately 6 billion worth of minerals). However in order to be as realistic as possible about this valuation you can not assume that the complete ore body contains the same grade (i.e. 2 copper and 1.5 gram per tonne gold).

Introduction to Mineral Deposit ModelsUSGS
An "ore deposit" is a mineral deposit that has been tested and is known to be of sufficient size grade and accessibility to be producible to yield a profit. (In these days of controlled economies and integrated industries the "profit" decision may be based on considerations that extend far beyond the mine itself in some instances relating

Introduction to Spectroscopy Analysis of Copper Ore
Earth s surface. Prospecting for copper then was relatively simple. Recently increased demand for copper resulted in numerous mines and the search for copper ore is now very competitive. When a copper deposit is discovered drilling is undertaken to determine the size and grade (concentration) of copper at the potential mining site.

Techniques for Collectors Cleaning native copper
A lot of the ore has basalt directly on it also quartz and prehnite are fairly common associations. The acid will not affect any of those. At times a thin layer of calcite will be directly in contact with the copper and if this is etched out you can sometimes break off any other outer coating.
