 — China - Minerals, Resources, Mining: China's most important mineral resources are hydrocarbons, of which coal is the most abundant. Although deposits are widely scattered (some coal is found in every province), most of the total is located in the northern part of the country. The province of Shanxi is thought to contain about half of the total; …

 — EIA estimates U.S. recoverable coal reserves at about 250 billion short tons, of which about 58% is underground mineable coal. Recoverable reserves at producing mines are the amount of recoverable reserves that coal mining companies report to EIA for their U.S. coal mines that produced more than 25,000 short tons of coal in a year. EIA ...

 — 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.
