Difference between mineral resource and reserve is

  • A.Reserve implies high degree of economic viability
  • B.Resource implies high degree of geological knowledge
  • C.Reserve implies high degree of economic viability and high degree of geological knowledge
  • D.Resource implies high degree of economic viability and high degree of geological knowledge

Answer: C

Reserve implies high degree of economic viability and high degree of geological knowledge

A reserve is the part of a resource that is economically viable to extract and is known with a high degree of geological confidence, so both are needed, which is option C. A resource may be less well known or less viable, so the first two options give only one condition and the last reverses the sense.

The other options, Reserve implies high degree of economic viability; Resource implies high degree of geological knowledge; Resource implies high degree of economic viability and high degree of geological knowledge, are not the answer to this question. This agrees with the official final answer key for the paper, which gives option C.
