3.9 SAMPLING PROCEDURES
In order to verify the reliability and compliance with Canadian National Instrument (NI) 43-101 standards
of the early drilling campaigns at Molejón, PML hired AAT Mining Services to ensure that PML drilling,
trenching, and survey activities were conducted to standards suitable for NI 43-101 reporting. AAT
concluded that the 1990’s drilling program was adequately validated by a drill hole twining campaign in
2006 and that 2007 drill core samples were analyzed to industry standards with minimal variance of
protocols or analytical results.
3.10 QUALITY ASSURANCE/QUALITY CONTROL (QA/QC)
A QA/QC protocol was established by PML at Molejón through the insertion of standard, blank, and
duplicate samples, with the objective of providing credibility to the database. It is the authors’ opinion
that sampling procedures and control during the PML 2006 and 2007 campaigns followed Industry
Standards and provided reliable samples and assay results for the purpose of Resource and Reserve
estimates following NI 43-101 standards.
3.11 ORE RESERVES AND MINERAL RESOURCES
Geovectra, S.A. (Geovectra) completed a geologic model and a NI 43-101 compliant resource estimate in
August 2009 for PML and issued a reserve estimate based on that model in March 2010. Based on the
revision of the Geovectra Block Model, Behre Dolbear & Company, Inc. (Behre Dolbear) concluded that
the Molejón deposit contains 33.3 million tonnes of measured plus indicated resources averaging
0.86 grams of gold per tonne using a cutoff of 0.20 grams of gold per tonne.
Metallurgical data obtained from nine crushed core column leach tests indicates that samples of various
portions of the low-grade mineralized material at Molejón are amenable to heap leaching with good to
excellent recoveries for the oxide material (80% to 98%) and modest recoveries for the fresh primary
sulfide ore (38% to 53%). These extractions were achieved with modest cyanide consumption (0.40 kg/t
to 0.93 kg/t) and modest lime (calcium oxide) consumption (0.76 kg/t to 4.81 kg/t).
