Grasberg is where the mine is located and the company is PT Freeport Indonesia and this is what they say about the future of their mining venture. This mine is considered the second most productive cooper mine in the world.
PT Freeport
Indonesia commenced mining operations in 1972 and in 1988 discovered
the Grasberg mine. Today, after significant production, the Grasberg
mining district contains one of the world’s largest recoverable copper
reserve and the largest gold reserve.
We have several projects in progress in the
Grasberg minerals district, primarily related to the development of the
large-scale, high-grade underground ore bodies located beneath and
nearby the Grasberg open pit. In aggregate, these underground ore
bodies are expected to ramp up over several years to approximately
240,000 metric tons of ore per day following the anticipated transition
from the Grasberg open pit in 2017. Development of the Deep Mill Level
Zone (DMLZ) is advancing. The DMLZ is expected to commence production
in 2015 and the Grasberg Block Cave mine is scheduled to commence
production in 2017....
