What is gold ore worth? That would make the gold in a one pound ore sample worth approximately 75 cents, and this is assuming that the ore is extremely rich.Many mines can run profitably on much lower grade ores, which might easily reduce the average value of ore down to 25 cents or less per pound.

The remaining 2 percent of gold ore reserves are located in Chhattisgarh, Madhya Pradesh, Kerala, Maharashtra, and Tamil Nadu. Key Points: i.Geological Survey of India (GSI) is engaged in geological mapping and mineral exploration (survey) of various mineral commodities including gold to explore the mineral-rich zones.
