Production

Historically the production of gold may be divided into two eras; before and after the California gold rush of 1848. Prior to the California discoveries, gold was a rather rare metal. Exactly how much was mined from ancient times is not known precisely but rough annual estimates are shown in the table below. They have been raised somewhat from previous calculations because these tended to focus only on the Mediterranean world and Africa, whereas gold was recovered in China, probably in Indonesia and certainly in South America from ancient times.

After the 1848 California gold rush, swiftly followed by that in Australia, production was lifted into another dimension. Output by 1852 was 280 tonnes (9 million oz) and an estimated 10,000 tonnes (321 m oz) was mined in the second half of the nineteenth century. By the end of that century the annual average was 400 tonnes (12.9 m oz). In the twentieth century production rose with price increases; first between 1935 and 1940, following gold’s rise to $35 an ounce and then again following the 1980 peak. By then new technology and better mining finance also had a significant influence, pushing output to over 2,500 tonnes (80.4 m oz) by the late 1990s. Total production throughout history will top 147,000 tonnes (4,700 m oz) by the end of 2002.
