Two days later, much of the Indian media was abuzz with the news that the Sonbhadra mines had gold deposits estimated to be around 3,350 tonnes and worth Rs 12 lakh crore, which is almost five times India’s current gold reserve.The reports quoted a District Mining Officer and estimated that with this find, India’s current gold reserves of 626 tonnes would jump to second place in the world behind the US, which holds 8,133.5 tonnes of gold.Even though the reports mentioned “gold deposits”, they equated it to actual gold mined and added the entire 3,350 tonnes to India’s current gold reserve.
