Mine Life. 2019. PTFI began openpit mining of the Grasberg ore body in 1990. The final phase of the Grasberg open pit was mined during 2019, including the removal of the open pit ramps. In aggregate, the Grasberg open pit produced over 27 billion pounds of copper and 46 million ounces of gold in the 30year period from 1990 through 2019.

mineral reserves. Here, we focus on the declining quality of copper ore reserves, what that does to the "head grade" (that is, the quality of the ore being mined), and its impact on future copper mine supply. As you will see, both ore reserves and quality of ore being mined are in pronounced declines.

The ore bodies mined form part of a semicontinuous, anastomosing mineralized shear zone up to 100 metres or more in thickness, that parallels the strike of the regional foliation. The shear zone and associated mineralization are affected by broad open folding and display a geometry similar to that described previously for the regional foliation.
