"What has Cascadero actually done to add value to the project. Nothing. No
drilling.  On their web site, Taca Taca was not even mentioned as their major
project.  This whole situation must be so annoying for Lumina. They like to own
a property outright, drill it out, and sell it to a major. The fact that they
deviate from this principle, and do a 50/50 JV must show that really believe
most of the high grade copper could be outside their own property.

 
 
Reason is Cascadero , only wanted to give up 50% , did u ever think that maybe Lumina wanted all of it ...
Nothing comes with a price amigo $$$$$$$$$
 
IMO....
 
Sit back and enjoy,,,,
