How can the classification of a mineral as an ore change?

Answer 1

A mineral deposit can become an ore when it becomes profitably extractable. Nevertheless, factors affecting prices include supply versus demand, production costs, stocks on hand, government (price controls), possibility of supply disruption, technology (substitution, recycling), geopolitics, and exchange rate.

Answer 2

To be an ore, the mineral deposit must be considered to be economically feasible to support extraction. If the price of a commodity that is produced from an ore increases in value sufficiently, a material that was once not economically feasible to extract could become so, and therefore considered an ore.
