How a plant Antofagasta Minerals "CENTINELA" (Chile) can have a 125 % recovery of copper?

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..."

Antofagasta Minerals "CENTINELA" (Chile)

Owners: 
Antofagasta Minerals 70% (Chile)
Marubeni Corporation 30% (Japan)


Let's count together (fase I):


They process  90000 tons of ore per day.
If the plant works 365 days a year, 24 hours a day, the plant’s productivity will be 32.85 million tons per year.

The copper content in the ore is 0.44 %.
The maximum amount of copper (theoretically possible) that they can extract from their ore is 144540 tons per year of copper.

They promise to get 180000 tons per year of copper.
How is this possible?
How can one extract and sell something that does not exist in principle?

How a plant Antofagasta Minerals "CENTINELA" (Chile) can have a 125 %  recovery of copper? (The recovery cannot be more than 100%!)

It is theoretically impossible to produce such an amount of copper at the plant. They will have a deficit of 35460 tons of copper per year.
In reality, the shortage of copper concentrate will be more than 102200 tons per year.

IMHO: This is not copper, gold and molybdenum which you can sell on the exchange!
Copper concentrate  from the plant Antofagasta Minerals "CENTINELA" (Chile) is an intermediate product that is cheap and requires further processing and significant financial costs.

They wrote: "...gold reserves are approximately 0.15 grams per ton of copper....".
IMHO: This is a small phishing word trap. I explain. This means that the ore contains 0.00066 grams of gold per ton of ore
A copper smelter will profit from this gold, but not "Centinela". The buyer will pay only for copper concentrate, but not for the gold and molybdenum that it contains.
