My take 

Teck and cuu are arguing sutilties of the existing  reports, some of which could make a big difference in overall numbers. Some are a bit variable such as exact location of a pit wall.  I do not know if they are close but you can tell the fustration in Elmer's voice.  No doubt Teck will take a glass half empty approach to technical reports and cuu will try to protect any information they have put out.  It seems they are talking on a weekly basis. If we get Teck shares it will not matter as much if the reports are lowered. As long as they keep talking and copper stays strong.  But then I have never got this story right.
