What is Gold Ore worth? High Grade Mining Ore

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.
