Underground mining requires less rock handling and waste. In the underground mine, Belmont mines one ton of waste to one ton of reaction-zone ore, so they average two tons of rock mined to two carats of cut emerald. Fifty percent of Belmont's production comes from open-pit mining and 50 percent from underground mining.
