· Table 6.5 shows the average grade of gold ores at Barrick operations. In 2016, the average grade of gold at major mines owned by Barrick was lower than 4 g/ton. There are many gold miners, including Barrick, that are processing gold ores having less than 1 g/ton of gold. One troy ounce of gold is equal to 31.10 g.
