Better than expected continuity in some high grade zonesGood news on page 86. The actual bulk sample gold content of 5923 oz compared fairly well to the Nov 2012 model estimate of 5248 oz. (13% difference on the conservative side) I think that is very good correlation for a geology based model. Also note that they were very conservative in the pre-bulk sample news releases and would only commit to seeing more than 4000 oz.
However, what jumped out at me is the following quote:
"The final metal and tonnes from the mill accounting were initially compared to the November
2012 Mineral Resource estimate in order to assess the appropriateness of the modelling
the knowledge gained from mapping and sampling in the bulk sample have shown that in some
of the extreme grade drilling intersections, the continuity of mineralization is far greater than
originally interpreted. Usually, an extreme grade would generally have continuity of at best a
metre or two, whereas extreme grades in both the east-west (e.g., 615L and associated
raises) and north-south (e.g., 426615 E crosscut and associated raises) components of the
stockwork system at Brucejack are continuous up to the tens of metres scale. The outcome
of this at Brucejack is that whilst the November 2012 estimate honours the input data, the
high grade mineralization was under-estimated due to the lack of samples in the high grade,
and the low grade was over-estimated – a function of the interpretation as to how to deal with
the extreme grades.
