History of Copper Coper was one of the first metals ever extracted and used by humans, and it has made vital contributions to sustaining and improving society since the dawn of civilization. Copper was first used in coins and ornaments starting about 8000 B.C., and at about 5500 B.C., copper tools helped civilization emerge from the Stone Age. The discovery that copper alloyed with tin produces bronze marked the beginning of the Bronze Age at about 3000 B.C.

Some metals, like iron and aluminium, are available in such large quantities that there's no squeeze on their availability. For others, the problem is potentially more acute - copper is among the three most-used metals in the world, essential for smartphones, desktop computers, industrial machinery, green energy initiatives and much more.

Cuture Unfortunately, copper isn't being discovered fast enough to keep up with demand. The lead time for a new copper mine stands at around 20 years due to the difficulty of exploring new sites, fluctuations in the price (and therefore commercial viability) of mining the metal, various regulatory restrictions from local governments, and several other factors. The quality of copper extracted from some of the major mines in the world is falling off rapidly, and it may be some time before the price rises high enough for other mines to be commercially viable - for the last year the copper price has been fairly flat as it bubbles under the $3 per pound mark, but experts estimate it needs to get up to $3.50 before there's enough financial incentive to create new mines (and it's difficult to predict when this will be).
