All our projects need more studies, drilling 

As long any deposit is still a project, not a mine, one can always do more drilling and more studies to advance it further. But one does not have to advance the project to the mine stage in order to sell it. A fair offer, based on the stage the project is at, can happen at any time.

We are relying on the increase price of copper not value creation.

Have you been reading the NRs for the past year of so? There was lots of value created and every work program on each property is doing just that, creating additional value.
