Tin Mineralisation in Nigeria: A Review | IIETA
Nigeria is endowed with vast but largely untapped solid mineral resources including tin ores (cassiterite and stannite). Tin, which is one of the oldest metals known to man, is invaluable in a wide variety of uses due to its intrinsic properties such as great malleability and ductility, low melting point, softness, corrosion resistance, non-toxicity, …

Mineral deposit | Definition, Examples, & Facts | Britannica
A mineral deposit that is sufficiently rich to be worked at a profit is called an ore deposit, and in an ore deposit the assemblage of ore minerals plus gangue is called the ore. All ore deposits are mineral deposits, but the reverse is not true. Ore deposit is an economic term, while mineral deposit is a geologic term.
