Something going down with all this activity....12 Jan 2020 12:54
Did anyone pick this up from the original NI 43 -101 report ?....page 9. Now I do know that during recent times the block model was changed to focus on high core resources... Does anyone else think that our resource model ito Silver could have got a bit bigger perhaps based on the below... I am thinking along these lines....
"The frequency distributions of lead, zinc, copper and silver sample populations were examined to identify the
presence of extreme high-grade outlier populations. Outlier values may result from sampling errors and can
exert an undue influence during block grade interpolation. They can result in over-estimation of block grades
and lead to poor reconciliation of expected and actual metal production. The methodology employed for
establishing the outlier limit was to examine the distribution of the sample population.
The selection of outlier values was based on the deviation of the grade distribution from a straight line in the
probability plot. There were no outliers identified by Micon for lead, zinc and copper. Based on the plot and the
above analyses, Micon identified silver samples above 200 g/t Ag, as outliers. There are four silver assays
greater than the specified outlier values. Those grades were reduced to the respective top-cutting value in the
assay database."
