Pulacayo Project Feasibility Study - Apogee Silver

Pulacayo 1 000 t/d Phase I Feasibility Study - NI 43-101 Technical Report
090644-3-0000-20-IFI-100
July 2011 to January 2012 Programs
The oxide zone diamond drilling program was carried out between September 2011 and
December 2011 and some oxide zone resampling of earlier holes was carried out in January
of 2012. Certified reference material insertion protocols for this period were the same as
those described above for the earlier Apogee program. The CDN SE-1 and PB138 reference
materials were used during this period and results for both typically fall within the mean ±2
standard deviations control limits for the project. Slight low bias within the control limits is
notable for Pb in CDN-SE-1 and Pb -138 results show similar slight low bias within control
limits for all three metals. Results for the two reference materials are interpreted as indicating
an acceptable degree of accuracy in the associated data set. Figures 12.14 to Figure 12.19
present certified reference material Ag, Pb and Zn results for this program.
