NI 43-101 Independent Technical Report Rev 02 January 22 nd , 2010
Mount Pleasant North Zone Preliminary Assessment (Project 6526-03) 10-1
SECTION 10.0 EXPLORATION
10.1 General
The reader is directed to the 2006, 2008 and 2009 WGM technical reports for details regarding all
of the exploration work conducted on the Mount Pleasant Property from 1994 to 2008 (Watts,
Griffis and McOuat, 2008, 2006, and 2009).
In November, 2006, Adex filed an assessment report to the Department of Natural Resources of
New Brunswick summarizing all exploration work from October 2005 to July 2006, including the
completion of the WGM NI 43-101 report (Boyd, 2006). Adex also filed a second assessment
report in covering all of the exploration work carried out on the property between the months of
January to November of 2008 (Boyd, 2008). This report included only the Phase 1 portion of the
diamond drilling program completed on the Fire Tower Zone and North Zone and has been filed
for assessment credit. To date, all of the exploration work has been carried out under the
supervision and direction of Dr. Trevor Boyd, the company’s geological consultant.
Since June, 2006, exploration work on the Mount Pleasant Property has advanced in the
following manner largely with reference to the North Zone:
In 2008, Adex has completed a two-phase 13,300 m definition and exploration drilling
program to expand and update the existing mineral resource estimate of the Fire Tower Zone
tungsten-molybdenum deposit and provide drillhole data to expand and prepare a new
NI 43-101 compliant resource estimate of the North Zone tin-indium deposit;
Diamond drilling was also completed to recover fresh drill core from the Fire Tower Zone and
North Zone for metallurgical bench and mineralogical testing;
The 2008 drill program involved completion of a thirty-six hole (8,859 m) definition diamond
drilling program to further define the mineral resources on the North Zone - the subject of this
report (see Section 11.0 for details);
Adex selected 262 pulp samples from the North Zone drill program and dispatched them for
SGS Lakefield Research Limited ("SGS Lakefield") to Activation Laboratories ("Actlabs") for
assay verification as part of their due diligence program (see Section 14.0 on Data
Verification);
The results of the Fire Tower Zone drilling and NI 43-101 compliant mineral resource
estimate of this zone can be reviewed by the reader in the WGM Technical Report filed in
early 2009 (Watts, Griffis and McOuat, 2009);
Additional sampling and analyses of historical drill core, not previously sampled within the
North Zone, was completed as recommended in the WGM report (Watts, Griffis and McOuat,
2006);
Adex submitted 144 historical drill core samples consisting of split drill cores, fill-in samples,
31 pulps and 4 rejects covering 75 historical drill holes for its Phase I assay verification at
SGS and/or Actlabs (see Section 14.0);
A total of 407 split core samples and 253 pulps were submitted from 49 historic drill holes for
assay verification at SGS and/or Actlabs (see Section 14.0);
Adex has completed an updated 3-D wireframe model of the North Zone incorporating the
new diamond drillhole data and infill sampling of historical drill core. This model was
presented to WGM to review and prepare a tin-indium Mineral Resource estimate of the
North Zone (see Section 17.0);
