Mount Pleasant North Zone Preliminary Assessment (Project 6526-03) 11-1
SECTION 11.0 DRILLING
11.1 General
Since early March, 2008, Adex has completed 49 drill holes in total for its Phases 1 and 2
programs for a total of 13,300 m, testing both the tin-indium-zinc-copper and tungstenmolybdenum-bismuth
zones throughout the Mount Pleasant Mine Property (see Figure 7-3).
These drill programs, operated under the supervision of Adex geological staff, were carried out in
order to verify the extent of known mineralization, to delineate the possible extensions of zones
and to expand on the existing mineral resource estimates at the Fire Tower Zone and North Zone
in compliance with NI 43-101. Drilling was also completed to recover fresh drill core material for
metallurgical bench and mineralogical testing.
The reader is directed to Watts, Griffis and McOuat (2008) for details regarding the results of the
Fire Tower Zone drilling program and directed to Watts, Griffis and McOuat (2009) for details
regarding the results of the North Zone drilling program. All of the 2008 drill hole collar locations
are shown on Figure 7-3. The North Zone drill results are briefly summarized below.
Adex completed a two-phase 36 hole diamond drilling program on the North Zone for a total of
8,859.1 m. Phase I, consisting of holes AM-08-01 to 07 and AM-08-10, was conducted from
February 27, 2008 to June 18, 2008. The remaining Phase II holes were completed from May 17
to September 11, 2008. The NI 43-101 compliant mineral resource estimate presented in the
Watts, Griffis and McOuat (2009) report for the North Zone utilizing the new and historic diamond
drill hole data.
The drill contract was awarded to Lantech Drilling Services Inc. ("LanTech") of Dieppe, New
Brunswick. Core size is "NQ". Down hole surveys were completed using a Reflex single shoot
instrument every 100 m. Upon the completion of each hole, the casing was left in for all holes, the
holes were capped and numbered and the collar location recorded using a global positioning
instrument ("GPS").
Adex logged the core, Rock Quality Designation ("RQD") and core recovery data was collected
and the core was photographed and split. Drill geologists use a binocular microscope to assist in
identifying the individual mineral phases within the drill core as mineralization is often very fine
grained and not visible to the naked eye.
A total of 2,667 spit core samples were collected from the North Zone drill holes, the majority of
the samples measuring 3.0 m in length. All analytical results were added to the company’s
GEMCOM digital database. At the end of the diamond drilling program, Adex dispatched 262 pulp
samples to SGS for assay verification as part of their due diligence procedures.
11.2 Drill Hole Surveying
In May and October, 2008, the drill collar locations for the 2008 drill holes and as many of the
historical drill collars possible were surveyed by Murphy Surveys (1990) Ltd. ("MSL"), located in
Old Ridge, New Brunswick. Surveying was done using a real time Trimbel G8 (base and rover)
receiver with a Trimble TSC2 data collector/controller. All points were acquired within an accuracy
of ±0.1 m or less. Coordinates are reported in NAD83. These data were added to the GEMCOM
Thibault & Associates Inc.
