13.3 Analysis
The accepted assay procedure for all Kupol samples is fire assay with a gravimetric
finish.
Exploration charges are 50 g with stated detection limits of 0.1 g/t Au and 0.5 g/t Ag;
prior to 2005, detection limits were 0.2 g/t Au and 1 g/t Ag.
Production and definition sample charges are 25 g with stated detection limits of 0.5 g/t
Au and 5 g/t Ag.
13.4 Quality Assurance and Quality Control
The on-site quality control program comprised of:
1. Insertion of standard reference material (standards) to monitor accuracy;
2. Coarse blank material (blanks) to monitor contamination and sample mix-ups;
and
3. Field duplicates (duplicates) and prep duplicate split re-runs to monitor
precision.
There is no information on quality assurance and quality control (QA/QC) programs
conducted prior to 2003.
Essentially the same QA/QC protocols have been used for trench, channel and core
programs from 2003 to the present, and include the insertion of certified reference
materials (CRMs) to monitor accuracy, coarse blank material (blanks) to monitor
contamination and sample mix-ups, and field duplicates (duplicates) to monitor
precision. The performance of quality control samples was monitored on a daily basis
as the results were received. The results were accepted or rejected based on criteria
established at the beginning of the program. If data were rejected, the data were
deemed a failure and withheld from the project database until the cause for the failure
was determined or the samples had been re-analyzed and the results accepted.
Requests for re-analyses were made immediately and the new results were returned
within two days. Results were charted monthly.
