You're wrong Bluefox a Reserve is the part of a Resouce (Indicated and or Measured) that has had modifying factors applied to it such as the cost of transport, cost of ponds, processing costs, recovery, capex, evaporation rates etc etc and is considered to be the part of the resource that is ecomomically extractable after the factors have been applied.

Here is a quote from google...

"An ore reserve is an economical minable part of a mineral resource where appropriate assessments and studies have been carried out to show that the deposit can be mined at a profit after consideration of all factors impacting a mining operation".
