  • Mining Valuation Lesson: Cut-Off Grade Theory

    Simply put, if it were to cost more than $96 to mine, treat, and extract the gold from that tonne of ore, it would be uneconomic to mine. Conversely,if the cost were less than $96, it could be economic to mine. But it’s not that simple. If all the tonnes of ore in a deposit contained the exact same grade of gold, it would be easy to calculate.
