I might be wrong but in this announcement KW says the following......

"Dr Wills said the thickness of CID intersected by the maiden FMS drilling program
was greater than the average estimated for the Company’s entire Hamersley
exploration target as previously defined by independent expert, Dr Richard Russell.
[As previous reported, Dr Russell has outlined a targeted resource of between 333
million tones and 380 million tonnes for the 100%-owned FMS E47/882 licence area.]
Dr Wills said further exploration drilling in the current RC program continued to
intersect CID mineralization on the Area."

Now doesnt this indicate potentially higher tonnage, why is this a bad thing, please explain!
