Buddy,
You wrote, "and all the ncu that we have,4%-5% grades of copper for years to come while mining], but in reality it doesn't show anywhere"

Now, if you read back through the company anns, it does, 'in reality" state that on the trial plant machinery that those grades were achieved.
It is probably better for the readers on the forum, to do due diligence before posting your emphatic assumptions.
Have a good day
