Steve, the lower the grade, the more rock you have to dig up, crush, transport and process to get the same amount of gold.
If the grade is 0.5 g/t, you need to mine 10 tonnes of ore to get 5 grams of gold. If the grade is 5 g/t, you only need 1 tonne of ore to get the same 5 grams.
The cost of processing each tonne of ore doesn’t really change, but if you need 10 times more ore for the same gold, the costs are 10 times higher.
Grade is absolutely key in mining.
