What is Gold Ore worth? High Grade Mining Ore

For example, lets say that a mine was processing ore valued at 1 troy ounce of gold per ton. This would generally be considered a very high-grade ore, worth mining in most cases. Using this hypothetical value of 1 ozt./ton, each pound of ore would contain approximately 0.0005 ounces of gold. Now let's assume that gold is valued at $1500 per

Gold in Quartz

Crushing the ore can free the gold and allow recovery by gravity-based methods. In fact it's very common that the gold in hard rock ores will range in the 30- to 200-mesh size range with most of the gold in the lower end of that range. The tried and true method for testing these ores in the field is hand crushing and panning.
