Much of far-West Texas is 'mineral classified'. This important feature of land ownership is a major reason why West Texas ranches are such great investments. Enacted in 1919, the Relinquishment Act, as interpreted by the Courts, reserves all minerals to the State in those lands sold with a mineral classification between September 1, 1895 ...

The ore quality, and density of a rock or metal ore, as well as its occurrence type, can directly affect the ore mining costs. It is therefore necessary to weigh the extraction cost against the metal value contained in the rock to determine which ore can be processed and which ore is too low a grade to be worth mining.

Minerals that are of economic value can be classified as metallic or nonmetallic. Metallic minerals are those from which valuable metals (e.g. iron, copper) can be extracted for commercial use. Metals that are considered geochemically abundant occur at crustal abundances of 0.1 percent or more (e.g. iron, aluminum, manganese, magnesium, titanium).

Ore deposits are usually classified by ore formation processes and geological setting. For example, SEDEX deposits, literally meaning "sedimentary exhalative" are a class of ore deposit formed on the sea floor (sedimentary) by exhalation of brines into seawater (exhalative), causing chemical precipitation of ore minerals when the brine ...

It has been argued that the reference to unextracted mineral products includes material such as ore in stockpiles that has not yet been processed. That is, the minerals have not been "extracted" from the ore, so Rule 121 declares those minerals must be classified as land. In our view, material that has been severed from the land must be classified
