"According to the World Gold Council, larger and better-quality underground mines contain around 8 to 10g/t gold, while marginal underground mines average around 4 to 6 g/t gold. Open-pit mines usually range from 1 g/t gold to 4 g/t gold, but can still be highly valuable.”Feb 21, 2020"
Each tonne of gold ore yields about 10 grams of gold at best.
