They crush it and get 3 ounces of gold out of it. (By any standards this would be VERY high-grade gold ore). At $19 per ounce, those 3 ounces of gold are worth $57. Except the gold isn't 24k. So it's actually only worth about $50. The mine with the stamp mill charges the miner $25 for stamping his ore. Now he's down to just $25.
