Copper concentrate deficit at the plant BHP "SPENCE GROWTH OPTION" (Chile) may reach more than 165000-123000 tons per year?

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..."

 
PLANT "SPENCE GROWTH OPTION" (SGO) Chile

Owners: BHP (Australia)

Let's count together:
They promise to have a productivity of 95000-105000 tons per day.

If the plant works 365 days a year, 24 hours a day, the plant’s productivity will be 34.7-38.3 million tons per year.

The copper content in the ore is 0.47 %.
The maximum amount of copper (theoretically possible) that they can extract from their ore is 163,000-180,000 tons per year of copper in concentrate.

They promise to get 185,000 tons of payable copper in concentrate per year.

How is this possible?
How can one extract and sell something that does not exist in principle?
How can copper recovery at a plant "PLANT "SPENCE GROWTH OPTION" (SGO, BHP) Chile be 114-103 %? (The recovery cannot be more than 100%!)

It is theoretically impossible to produce such an amount of copper at the plant and they will have a deficit of 22,000-4,900 tons of payable copper in concentrate per year.

How can 52000 tons of copper be extracted from 50000 tons of copper in concentrate?

IMHO: This is not copper which you can sell on the exchange!
This is a copper concentrate that requires additional processing! Unknown copper concentration in concentrate.
In reality, the shortage of payable copper in concentrate will be more than 40,000-55,000 tons per year.
Copper concentrate deficit may reach more than 165,000-123,000 tons per year.
