Answer to Question 1

The price of gold went up, and new technology made it possible to extract gold more economically

Answer to Question 2

Ore is a metallic reserve. This means that it must be economically exploitable. The factors controlling
the economics of mining a given substance are not constant. Something that is economically
exploitable at one time may not be at a later time and vice versa.
