11.2 Q UALITY A SSURANCE/QUALITY C ONTROL P ROGRAM
The same QA/QC program was in place for Coronation Minerals, Northern Platinum
and Prophecy Platinum as described below.
Blanks, Standard Reference Material (SRM), and duplicates were inserted into the
sample stream every 20 th sample.
A duplicate sample was taken with every 20 th sampling of core. The selected sample
was sawn in half and both resulting pieces were also sawn in half. This quartered
core was then placed into two different sample bags with different sample numbers
and sealed.
The SRMs came from Natural Resources Canada and Analytical Solutions Limited.
These were inserted into the sample stream immediately after the second duplicate.
The SRMs are WMS-1a, WPR-1 and WGB-1. The certificates for the SRMs are
found in Appendix B.
Sample blanks were obtained from two sources: granodiorite from a local road metal
quarry, and garden marble from hardware stores in Whitehorse, Yukon. A blank
sample was inserted into the sample stream after the SRM.
Tetra Tech has not compiled or reviewed the results of the QA/QC programs for
either the Coronation Minerals or Northern Platinum drilling programs and cannot
comment on the validity of the result.
In addition to the field-inserted QA/QC program, the laboratories operate their own
laboratory QA/QC system. The labs insert quality control materials, blanks and
duplicates on each analytical run.
No secondary laboratory check assaying was completed on the recent drilling
programs.
Tetra Tech believes the sampling practices of Prophecy Platinum meet current
industry standards. Tetra Tech provided Prophecy Platinum with recommendations
on ways to improve the current QA/QC program to make it more effective. These
recommendations include:
• The results of the field-inserted QA/QC data should be reviewed by the
company geologist and it is also good practice for the geologist to review the
laboratory-internal QA/QC data.
• A selection of course rejects or pulps samples up to 10% of the data set
should be sent to a second laboratory as part of the QA/QC program.
• The insertion rate of one blank, one duplicate and one SRM should be
maintained for every 20 samples.
