[@Mihndar] Someone else just discovered Copper. But I will edit it.

More than one race can discover copper. Most of us will end up discovering all the same technologies along the way, unless people think of something creative or different from the non-traditional path. You can concentrate on certain things though, to be for example ahead of most people in weapons technology.

Smelting iron requires significantly higher temperatures, which requires a bellows and a smeltery and all the relevant equipment, which won't really be possible until we get to the classical era.
