Was the nature and appropriateness of the<br />
estimation technique(s) applied <strong>report</strong>ed?<br />
(Includes any assumptions regarding the<br />
treatment of extreme grade values, domains,<br />
interpolation parameters, and the maximum<br />
distance of extrapolation from data points.)<br />
Were check estimates, previous estimates<br />
and/or mine production records available and<br />
does the Mineral Resource estimate take<br />
account of such data?<br />
Were there assumptions made regarding<br />
recovery of by-products?<br />
Have any deleterious elements or other nongrade<br />
variables of economic significance<br />
been estimated (e.g. sulphur for acid mine<br />
drainage characterization)?<br />
In the case of block model interpolation, have<br />
the block size in relation to the average<br />
sample spacing and the search been<br />
denoted?<br />
Were any assumptions made regarding<br />
modeling of selective mining units?<br />
Were any assumptions made about<br />
correlation between variables?<br />
Have the processes used for validation,<br />
checking, and comparison of the model data<br />
to drill-hole data been <strong>report</strong>ed? Did the<br />
validation process include any use of<br />
reconciliation data?<br />
Were the tonnages estimated on a dry basis<br />
or with natural moisture, and has the method<br />
of determination of the moisture content been<br />
denoted?<br />
Has the basis of the adopted cut-off grade(s)<br />
and/or the quality parameters applied been<br />
detailed?<br />
