I think the annual mine production is around 2,500 tonnes / year. But ths figure can be slightly confusing, since it doesn't take in to account surplus gold supply from gold scrap and other sources.
that really helped, i know one thing that out of total 2400-2500 tonnes, India imports 1000 tonnes of gold every year.
Hmm... total supply must be significantly more than 2,500. I had noted down earlier that gold scrap is not included in those figures. So I think 3,500 tonnes a year will be a conservative estimate. India imported 958 tonnes of gold in 2010, so that will be about 28-30%.
Global gold mine production increased by 3 percent over the third quarter of this year to approximately 659 tonnes, as a number of new operations either came online or increased production. Increased Australianproduction contributed to the majority of the output growth, although Mexico and Argentinaalso exhibited positive production on an annualized basis. Offsetting the impact of these developments was a decline in production in Indonesia, Russia and Peru. The decline in production in Indonesia should not be a point of concern for investors as its production totals in 2009 had increased almost 66 percent last year, the largest one year production increase of any country in the world. Last year the only other top 10 gold producing country in the world to demonstrate double digit growth in annual production was Ghana, with a 13 percent increase.
