The four validation tests that constitute the NASMD QAQC
algorithm--the range, streak, deviance, and step tests--flagged 0.
Since commencement of drilling, Dacian has implemented a consistent QAQC
system utilising standards, blanks and duplicate samples.
program was designed and approved by Michael Dufresne, the Qualified Person.
He adds that site managers need to have a high level of QAQC
and coordination on megaprojects to deliver on high expectations.
Rigorous sampling, QAQC
, and logging procedures were applied to 2011 drilling which has lead to a high level of confidence in the data.
When we embark on a job, we need QAQC
, we need HSE officers, we need administration and backup facilities.
analysis between the two types of drilling has highlighted no significant issues with sampling and representivity.
Although the drill hole data density would otherwise be sufficient in parts of the deposit to support a higher level of confidence, due to the lack of QAQC
data and use of historical in situ bulk density information, Golder has not classified any of the Mineral Resource as Measured.
Results are monitored for key elements, and in cases of QAQC
issues, re-analysis is requested.
