Hi Westcott,
Referring to 2 April release?
What they've done is highlight a zone of higher Fe content in some holes.
So for hole 199:
Between 39.8 and 67.8 metres (width 28 metres) there's an average of 56.4% Fe.
But within that range - between 43.9 metres and 60.17 metres (15.7 metres width) - there's an average 58.1% Fe.
Hope this answers the query!
