How can copper recovery at a plant CODELCO "División Radomiro Tomic" (Chile) be 155-124 %?

From the series of publications 
"So they create a fairy tales for the investor" - 
"They draw up the necessary documents
and begin to search for the simpleton..."

CODELCO "División Radomiro Tomic" (Chile)

Owner:  Codelco (Chile)

Let's count together:

They process  115000 tons per day.
If the plant works 365 days a year, 24 hours a day, the plant’s productivity will be 42 million tons per year.

The copper content in the ore is 0.51 %.
The maximum amount of copper (theoretically possible) that they can extract from their ore is 214100 tons per year of copper.

CODELCO "División Radomiro Tomic" has already received 332667 tons of copper in 2018 and 266415 tons of copper in 2019.
How is this possible?
How can one extract and sell something that does not exist in principle?

Copper shortage should be 118567 tons per year of copper in 2018 and 52315  tons per year of copper in 2019.

How can copper recovery at a plant CODELCO "División Radomiro Tomic" (Chile) be 155-124 %? (The recovery cannot be more than 100%!)

It is theoretically impossible to produce such an amount of copper at the plant CODELCO "División Radomiro Tomic" (Chile). How did they produce more copper what is contained in the ore?
