high grade zn at manbarrum

From the half yearly posted today: "It was also verified that geological/mineralogical settings within the central zone have the potential for a loss of zn sulphide during the drilling procedures. Results record highly significant values of 15 - 35% from sumps located next to several RC holes. Losses of high grade material from drill core are also evident due to soft fine grained sphalerite-dolomite drill techniques will be utilsed in 2008 to improve recoveries of high grade material".....get it, all you losers who are selling !!!!!!
