In the last 6,000 years a little over 125,000 tonnes of gold has been mined. But this history is clearly divided into two eras: before and after the California gold rush of 1848. Some calculations suggest that up until then scarcely 10,000 tonnes of gold had been excavated since the beginning of time. Thus more than 90% of the world's gold has been produced since 1848.

There's an outside chance that you might have been misled. When I look at the chart you provided, I see that the Y-axis is labelled in Millions of Ounces and not millions of tonnes. I don't think that the chart supports the idea that over 2,000 tonnes of gold were mined in any year.
Along these lines, I found a website you might be interested in: Gold history
