This list contains possible values for the resource tag. Editors should keep in mind the complexity, vagaries and contradictions of the resources industry. For example, Heavy Mineral Sands mines provide the ore for a number of metals including Titanium which comes from the mineral Rutile. Rutile from the same mine may also be used as an industrial mineral (white pigment). So do you call it a Heavy Mineral Sands, Titanium or Rutile mine. In this case I suggest listing Rutile and the other mineral ores produced (commonly Ilmenite and Zircon).

|resource=clay||Clay from clay pits are used to make pottery and bricks. Old clay pits are often filled with water for recreational purposes||wikipedia:clay|
|resource=coal||includes black coal, brown coal (lignite), anthracite, coking, steaming. Peat is separated. It was discussed in the forum that coal should not be further distinguished||wikipedia:coal|

More comprehensive list
There are a number of metals left off because they are only produced as a by product. There is a large number of industrial minerals, the major ones are listed, more can be added. This list doesn't contain the already mentioned resources (quick reference list).

Chromium –> list as chromite which is the only ore of chromium
Heavy mineral sand – list as individual minerals e.g. Ilmenite; Rutile; Zircon
Iron –> see Iron Ore
Molybdenum –> see Molybdenite
REE – Rare earth elements list individual minerals/metals where possible
Titanium –> use Rutile
