How can copper recovery at a plant TECK "QUEBRADA BLANCA" (Chile) be 242-160 %?

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..."

TECK "QUEBRADA BLANCA" (Chile)

Owners: 
60% Teck Resources Chile Ltda. (Canada)
25% Sumitomo Metal Mining Co., Ltd. (Japan)
10% Empresa Nacional de Minería (ENAMI, Chile)
5% Sumitomo Corp. (Japan)

Let's count together:

They process  143000 tons per day.
If the plant works 365 days a year, 24 hours a day, the plant’s productivity will be 52.2 million tons per year.

The copper content in the ore is 0.38 (0.25) %.
The maximum amount of copper (theoretically possible) that they can extract from their ore is 198360 (130500) tons per year of copper.

They promise to get 316000 tons per year of copper.
How is this possible?
How can one extract and sell something that does not exist in principle?

Copper shortage should be 117640 (185500) tons per year of copper.

How can copper recovery at a plant TECK "QUEBRADA BLANCA"  (Chile) be 160 (242) %? (The recovery cannot be more than 100%!)

IMHO: It is theoretically impossible to produce such an amount of copper at the plant TECK "QUEBRADA BLANCA"  (Chile) and they will have a deficit of 117640 (185500) tons per year of copper. How did they produce more copper what is contained in the ore?
