Ahhhh i found the missing link.. It shows here down to .3%.......... It is all very clear now..

The updated resource is based on 67 holes (3,998 metres) lying within the mineralized envelope. Drill hole spacing is approximately 30 metres for the Indicated Resource and 70 metres in the areas of Inferred Resource. The limits of the resource envelope were determined by the natural break in the mineralization at 0.3% Ni, and extends approximately 125 metres along strike, 1200 metres down-dip, and 35 metres in thickness. A block model was constructed and grades estimated using Ordinary Kriging methods with composite samples 1.5 metres in length. A strong correlation between Ni and Specific Gravity (95%) was observed, and density-weighting was used in the estimates. Grade variography on the individual elements reported were used to determine optimum search parameters used in the interpolations.
