splits and rejects selected from various holes for this purpose. In total, results from 442 data
pairs were reviewed for this period and are presented in Figure 12.32: Pulp Splits and Reject
Duplicate Samples - Ag G/T (N=442), Figure 12.33: Pulp Splits and Reject Duplicate
Samples - Pb % (N=442) and Figure 12.34: Pulp Splits and Reject Duplicate Samples – Zn
%(N=442) for Ag, Pb and Zn respectively. A high degree of correlation exists between
sample pairs for all three metals and all show 0.999 correlation coefficients. Analytical results
included in the check sample program were determined at the ALS facility in La Serena,
Chile and original project results were from the ALS facility in Lima, Peru. Since January
2010 and starting at PUD 140 all second laboratory cross check analysis are done at SGS in
Lima Peru.
