Pulacayo Project Feasibility Study - Apogee Silver

Pulacayo 1 000 t/d Phase I Feasibility Study - NI 43-101 Technical Report

Figure 11.1: Apogee Core Logging Facility
The secured 6 mm plastic sample bags are grouped in batches of 6 to 10 samples and
secured in a larger plastic mesh bag in preparation for shipment to the ALS Chemex (ALS)
preparation laboratory located in Oruro, Bolivia. All bagged samples remain in a locked
storage facility until shipment to the laboratory. Samples are transported from the core
storage area to the ALS facility by either Apogee personnel or a reputable commercial
carrier. Sample shipment forms are used to list all samples in each shipment and laboratory
personnel crosscheck samples received against this list and reported any irregularities by fax
or email to Apogee. Apogee advised Mercator that it has not encountered any substantial
issues to date with respect to sample processing, delivery or security for Pulacayo programs.
11.2 Sample Preparation from 2002 to 2003 ASC Programs
Site procedures pertinent to ASC were not documented in support information reviewed by
Mercator. However, Apogee staff familiar with the earlier program indicated that procedures
were generally similar to those employed by Apogee with respect to core logging, sampling,
transport of samples and security. All ASC drill core samples were processed at the Oruro,
Bolivia laboratory of ALS Chemex, with those from the first phase of drilling being analyzed at
ALS Chemex (formally Bondar-Clegg) facilities in Vancouver, BC, Canada. In both instances,
standard core preparation methods were used prior to elemental analysis.
11.3 Drill Core Analysis from 2006 to 2012 Apogee Programs
Apogee staff log and sample drill core and carry out immersion method specific gravity
determinations but do not carry out any form of direct sample preparation or analytical work
