You do know that companies always select their rock chips right?...

You do know that companies always select their rock chips right?
They can literally take a chip of any rock to get it assayed,
And pick the best ones,
Obviously one would aim for the targeted minerals !!!!

You do know that when companies are looking for gold,
They often get prospectors to use their gold detectors to find signs of gold,
Yet it is clear to all that the entire tenement is not one huge gold nugget?
No one expects hundreds of acres of solid gold....

That is how silly what you are saying is.

To further confirm this they often also pan for gold,
To check that it actually exist on their tenement before drilling.
It doesn't mean the entire tenement is gold,
Or any other mineral !!!!

Anyhow SUM seem to already be on the way to completing aerial surveys,
See that's the point,
To find and confirm the best spots to drill.

That is the smart way to do things,
To get best bang for buck,
And Drill the best possible ground !!!!
