security of drill core. A core check sampling program consisting of 9 quarter core samples, 2
duplicate split samples, 2 quality control samples, and 4 reject material samples was also
carried out. A drill collar coordinate check program was also completed during the visit, with
collar coordinates for 7 Apogee drill holes collected using a hand-held GPS device for
comparison against database records. Apogee President, Mr. Chris Collins, P. Geo, and
Exploration Manager Mr. Hernan Uribe provided technical assistance and professional insight
during the site visit.
During the core inspection and review process, several previously sampled core intervals
representative of the Ag, Pb and Zn grade ranges of the Pulacayo deposit were selected
from drill holes PUD111, PUD134, PUD140, PUD144, PUD175, PUD188, and PUD203 for
use in the Mercator check sampling program. After mark-up and photographing of sampled
core intervals by Mercator, Apogee staff carried out quarter core sampling of the designated
core samples under Mercator supervision. Resulting bagged, labeled and sealed core
samples were securely stored at the Apogee facility until being transported by commercial
courier to SGS del Peru S.A.C for analysis.
Observations regarding the character of the landscape, vegetation, site elevations, surface
drainage, road/drill pad features, drill sites, mine accesses, exploration conditions, and core
logging and handling facilities were noted during the site visit. Based on observations made
during the site visit and discussions with Apogee staff and consultants, Mercator determined
that, to the extent reviewed during the visit, evidence of work programs carried out to date on
the property is consistent with descriptions reported by the company and that procedures
employed by Apogee staff are consistent with current industry standards and of good quality.
12.2.2 26 April to 28 April, 2012
Author Cullen visited the Pulacayo site during the period 26 April to 28 April 2012 the
purpose being to carry out additional review of on-going drilling and resource estimation
program work pertaining to oxide zone mineralization not included in the previous resource
estimate. Reviews of site drill program components, including discussion of protocols for
lithologic logging plus storage, handling, sampling and security of drill core were carried out
at that time, with specific focus on the 45 drill holes completed late in 2011 that targeted
oxide zone mineralization of the TVS.
Trenched areas, TVS surface exposures and drilling locations associated with assessment of
the oxide zone were visited and a general overview of the site and facilities was obtained
(Figure 12.1 and Figure 12.2). A core check sampling program consisting of 24 quarter core
samples, 1 quality control reference material sample, and 1 blank sample was also carried
out, along with field location checking of drill collar coordinates for 14 oxide zone drill holes.
Collar locations were checked using a hand-held GPS device for comparison against
database records and acceptable results were returned from both programs. Details of these
are presented below in report section 12.3.5.
An active test mining area developed by Apogee on a subsidiary hanging-wall vein (ramale)
interval of the TVS near the San Leon tunnel was also visited during the April 2012 trip.
Stoping of the vein was being carried out at that time over a horizontal width of approximately
1.5 m to 2.0 m and stoped material was being stockpiled on surface for use in future
metallurgical testing programs (Figure 12.3).
