Ann: High Cu Assays and Significant Pb/Zn Intersections at T3-MOD.AX, page-6

Exploration companies estimate grade through drilling and assaying. The average grade of copper ores in the 21st century is below 0.6 percent copper, with a proportion of ore minerals being less than 2 percent of the total volume of the ore rock.

1.97%, 2.9%, and 0.76% is well above the average of 0.6%.

This is higher than average copper.
