How good a copper project might "Copper Duke" be?

[goodape]

Can anyone offer evidence Core Gold Inc.'s "Copper Duke" exploration project might have a future as a buildable copper project?

I know it is considered a Copper-Gold project . . . 
      Target One had Au of .2 to 1.3gpt Au as well as 0.2 to 2.6% copper
      Target Two had Au of .2 to 61.5gpt Au
      Target Three had 63m at 1.7gpt Au

Is there further evidence of copper beyond the samples at Target One?

I am not a copper investor, so I don't know what it means when % copper is stated.  My impression is projects are built to extract copper when its 1% copper orebody, is this correct?

Can you help me figure this out?  
Thank you.

As a copper project it is quite extraordinary. Here is a 2007 article on it when SBI was about to take a piece of it. The Ecuador political climate stalled that deal. But now it is likely to be the crown jewel of Core. At 2% and more of copper and the size of the area it will have a lot of copper and of course gold. https://www.kitco.com/pr/1267/article_05222007103253.pdf The current board and
