With the instability and uncertainty still inherent in Angola, this would seem the most prudent course of actions.
Have to remember that if LOM manage to do as it hopes, DeBeers is going to be majorly peeved as it will secure supply concerns in the short term, thus reducing the premium they are currently attracting due to supply fears.
So, I would say it's very important for LOM to secure it's claim on the area further with the Alluvial mining license before releasing too much promising/positive information about the Kimberlites.

IF (and these speckys are always an IF) this is the case, then it is definitely in the shareholders interest to time the information release carefully.
