SUMMARY
The Iron Range property is located in southeastern British Columbia within the Goat River area 15km
northeast of the town of Creston. This 56,385.68 hectare land package within the Nelson/Fort Steele
Mining Districts is currently owned 100% by Eagle Plains Resources Ltd. In 2010 Providence
Resources Corporation entered into a joint venture with Eagle Plains Resources Ltd. to earn a 60%
interest in the Iron Range property through expenditures to total $3,000,000.
The claims are situated along a high pressure gas pipeline and a high voltage hydro-electric line which
follow the CPR mainline and Highway 3 South.
The Iron Range is a Middle Proterozoic regional scale linear fault structure known to host significant
iron oxide mineralization. The Iron Range deposits were originally staked in 1897 and were covered by
Crown Grants held by Cominco Ltd. and the Canadian Pacific Railway. When the grants were reverted
in 1999, Eagle Plains Resources Ltd. staked the ground as the FeO and IR claims. Past work on the Iron
Range deposits by Cominco Ltd. in 1957 was directed toward the considerable iron oxide resource and
consisted of trenching and very shallow (20m depth) diamond drilling in the area along the Iron Range
fault zone. Ongoing work by Eagle Plains Resources Ltd. from 2000-2005 focused on exploring the
potential of the Iron Range fault zone and surrounding area as a conduit and host for both Iron oxideCu-Au (IOCG) mineralization and sedimentary exhalative (SEDEX) Ag-Pb-Zn mineralization.
In 2008 Eagle Plains Resources Ltd carried out a diamond drilling program focusing on the Union
Jack, O-Ray, Keepsake, Rhodesia and Unnamed mineral occurrences located within the northern
portion of the Iron Mountain Fault Zone. The two primary objectives of the drill program were to test
for IOCG mineralization and define a near surface iron resource. Near surface high-grade Au
mineralization was intersected at the O-Ray Minfile occurrence.
The 2009 exploration program was completed in two phases. Phase I accommodated ongoing academic
studies, and explored in detail through mapping, trench and soil sampling the O-Ray showing area.
Phase II consisted of diamond drilling to exploit and expand the near surface high grade gold drill
results from the 2008 program.
Through a joint collaboration of industry and university known as the MITACS Accelerate Program,
Masters student Michael Galicki continued field work for his thesis titled: 'Geochronology and
Petrology of Iron Oxide Mineralization, Creston, B.C'. and 'Paleomagnetism of the Iron Range Iron
Oxide Deposits'. Eagle Plains Resources Ltd. funded 50% of the work.
TerraLogic Exploration Inc. conducted a systematic trench and soil sampling program over a series of
three east-west oriented trenches on the Iron Range iron oxide structure within the historic O-Ray
showing area. This showing yielded near surface high-grade drill results in 2008 which prompted
geological mapping and continuous one metre channel and chip sampling to determine if the gold
mineralization continued to surface. Excavation of these historic Cominco trenches encompassed an
area approximately eighty metres north-south by 25 m east-west. In addition, close spaced soil samples
were taken from nine soil lines over the area of trenching.
Results of the program indicated structural controls on the gold mineralization at depth.
A joint venture agreement with Swift Resources Ltd. in the latter part of 2009 resulted in a seven hole
diamond drill program. A total of 579.17 metres of NQ2 size core were drilled in proximity to the O-
Ray showing, with the vast majority of drill holes vectored at intersecting the gold mineralization from
the 2008 program.
The total expenditures for the combined 2009 exploration programs amounted to $ 403,389.04
The 2010 and 2011 diamond drilling exploration program was initially based on drill testing a large
1.6km x 1.2km ovoid EM anomaly within the southeast portion of the tenure area. The anomaly was
delineated by a 2004 GeoTech Ltd. high resolution VTEM airborne survey. Data processing and
interpretation by Condor Geophysics Ltd. deemed the anomaly to be near surface and conformable to
bedding. The anomaly was interpreted to lie at or near the Lower-Middle Aldridge Formation contact
(LMC) which is the stratigraphic horizon hosting the world class Sullivan SEDEX deposit
approximately 55km to the northeast.
The intersection of tourmaline bearing metasediments with occasional stratiform laminae of pyrrhotite,
pyrite, and lesser chalcopyrite in IR10-001 near the LMC was interpreted as being an environment
proximal to a hydrothermal 'vent'. This prompted additional drilling and the expansion of the original
$200,000 budget. Drill holes IR10-002, IR10-003, and IR10-004 continued to drill test within the
perimeter of the EM anomaly, intersecting additional tourmaline development and minor albite-silicasericite alteration. Expansion of the budget by Providence Resources Ltd. to $650,000 led to additional
drilling east of the EM anomaly footprint. In an effort to locate massive sulphides interpreted to
possibly lie in proximity to the vent source, IR10-005 intersected narrow (2-4cm) sub-vertical massive
sulphide veining in the form of galena and sphalerite. The budget expanded and the drill program
continued through to April 2011 generating twenty-nine drill holes at an expenditure cost of
$1,867,790.77. Assessment report costs amount to $11,806.50 bringing the total expenditures for the
Phase I and II portions of the Iron Range program to $1,879,597.27.
Phase III of the 2011 program (the subject of this report) consisted of soil sampling, geological
mapping, induced polarization ground and downhole geophysics and airborne geophysics.
4245 soil samples were taken in 2011 over six areas: Arrow East, Row, Canyon, Canyon East, Gap
and 6 Mile. A number of base and precious metal anomalies were identified/refined. Two of the
strongest anomalies occur on the Row (Pb-Zn-Cu-+/-As) and the Canyon (Pb-Zn-Cu-Au-As) grids.
Results of a VTEM survey over the Row grid only produced a small number of weak conductors.
Results of a ZTEM survey obtained, a number of interesting conductive structures across the property.
This data is currently under review/reinterpretation by Condor Geophysical Ltd.
Total expenditures for Phase III amounted to $944,013.75.

INTRODUCTION
LOCATION AND ACCESS
The central portion of the Iron Range property is located 15km northeast of Creston, B.C. between the
Goat River and Arrow Creek drainages (Figure 1). The claims are centered at approximately Latitude
49°7’N, Longitude 116°23’W (NTS 5442000N / 544000E) on NTS Map sheets 82F008, 82F009,
82F018, 82F019.
Access to the south central portion of the property is via a network of forestry service roads (FSR's)
which include the Arrow Creek and Crackerjack Creek FSR's. The northern and central portions can be
accessed from the junction of Highway 3 and the hamlet of Kitchener. The northern and eastern part of
the property is accessed via the Iron Mountain and Hall Lake FSR's. The latter leads to the Iron
Mountain FSR and is accessed west off of the main Goat River FSR just north of the 11.5km marker.
The property is bisected lengthwise by an historic Cominco exploration trail which runs roughly
parallel to the main Iron Range Fault structure and is easily accessed using an ATV from the south and
4WD vehicle from the north. Access to the southeast portion is from the Thompson Mtn. FSR in
Canyon, a hamlet of Creston. The southernmost portion is gained south off of Hwy 3 east of Creston
through the Russell Ck. and Carrol Ck. FSR.
The Six Mile and Crackerjack Creek areas have been extensively logged, and the south central part of
the property is partially within the Arrow Creek Community Forest License.
A well developed transportation and power corridor lie at the southern end of the Iron Range claims,
where a new high pressure gas pipeline and a high voltage hydro-electric line follow the Canadian
Pacific Railroad (CPR) mainline and Highway 3 south. The rail line provides efficient access to the
Cominco Ltd. smelter in Trail, B.C.
The claims cover alpine to sub-alpine terrain within the Iron Range of the southern Purcell Mountains.
Elevations range from 800 to 1900m, with moderate to very steep topography.
Vegetation at the lower elevations consists of lodge pole pine, balsam fir, with lesser birch, aspen,
cedar, and hemlock flanking drainage and riparian zones. The mid to upper elevations contain sparse
populations of white pine, local cedar, and a progressive increase in hemlock and balsam fir, the latter
dominating at the height of land.
Outcrop exposure is good on ridges to moderate at lower elevations. The central part of the property is
a broad N-S oriented ridge which is bisected by the main Iron Range Fault structure.
Tenure
The Iron Range property consists of 56,385.68 hectares. The claims are owned 100% by Eagle Plains
Resources Ltd. The discovery of base and precious metal mineralization in 2010 prompted the staking
of an additional 36,593.68 hectares from a previous 19,792.00 hectares.

Table 1 – Claims Status
History and Previous Work
The Iron Range prospect was discovered and staked in 1897 along an extensive belt of iron oxide
showings. Initial work included several small shafts, adits, and trenches, and later with limited
diamond drilling to a maximum depth of 20m. Many of the original claims on the Iron Range were
established as Crown Grants. In 1939, The Consolidated Mining and Smelting Company of Canada
Ltd., along with its parent company CPR, acquired the main claim block on the northern part of Iron
Range Mountain. The claims were evaluated by CM&S (pre-Cominco Ltd., now Teck Ltd.), to assess
the potential for a large iron resource. As part of this evaluation, Cominco Ltd. completed an extensive
trenching program in 1957, exposing the Iron Range structure and mineralization over more than 4km
strike length. In the 1980’s Cominco Ltd. completed regional-scale work through the area as part of its
Sullivan SEDEX search program. This included reconnaissance-scale mapping, contour soil
geochemistry, and UTEM surveys. Most of the Iron Range Crown Grants were held by Cominco –
CPR until 1999 when they were reverted. Eagle Plains Resources Limited re-staked the original Crown
Grants as the FeO and IR claims on the day the historic grants lapsed. These claims cover the main
part of the Iron Range structure worked by Cominco including the historic Union Jack crown grant in
the north and the Rhodesia crown grant in the south. Eagle Plains subsequently staked the TCK claims
in the area of Thompson Creek to cover the historic Great War crown grants.
The May Bee MinFile showing has seen historical (pre-1950s) exploration with two levels developed
on the south end of the current holdings. This mineralization is proximal to the Iron Range fault
system, and consists of chalcopyrite and associated gold and silver values in a 0.3m to 1.5m wide
quartz vein hosted by a gabbro sill. The Virginia MinFile occurrence also saw some historic small
scale development with two levels developed approximately 40m apart on a galena bearing quartz vein.
The showing area was also tested by diamond drilling and electromagnetic surveying in the early
1950’s.
2001 fieldwork by Eagle Plains consisted of grid and contour soil geochemical sampling along the
trace of the Iron Range fault system. Results from the work program indicate that the Iron Range
structure has a geochemical signature consistent with other Fe Oxide Cu-Au-U-REE deposits. The
total cost of the 2001 geological exploration work on the Iron Range Project was $62,356.62.
In 2002 Eagle Plains Resources retained Dr. Lucas Marshall to undertake a compilation study on the
Iron Range area and to oversee the 2002 fieldwork. Mr. Marshall has a Ph.D. from James Cook
University in Queensland Australia with a doctoral thesis on Olympic Dam type deposits. 2002
fieldwork included geological mapping with an emphasis on structural and alteration mapping at a
scale of 1:20,000. Grid and contour soil geochemical sampling aimed at constraining soil anomalies
established in 2001 were also conducted. A limited rock geochemical sampling program was
undertaken in order to assess the geochemical character of the Iron Range metasomatic ironstones and
associated alteration.
Results and conclusions from the 2002 work included:
• Iron Range metasomatic ironstones are marked by significant enrichment in Fe2O3, Au, V, Co, Cr, Ni,
SiO2 and Sc;
• Geochemical targets along and adjacent to the Iron Range fault zone exhibit enrichment in multiple
IOCG indicator elements including Cu, Co, Ba, La and P;
• Identification of SEDEX style geochemical anomalies within a narrow stratigraphic interval near the
contact between the Middle Aldridge and Ramparts facies. This stratigraphic interval is likely the timeequivalent to the Lower-Middle Aldridge contact (LMC) where the Sullivan Ag-Pb-Zn deposit is
located;
Mr. Marshall recommended more work on the project, including assessing both SEDEX and IOCG
targets. The total cost of the 2002 geological exploration work on the Iron Range Project was
$67,506.36.
In 2003, Eagle Plains carried out soil geochemical surveying in areas of interest identified by previous
work programs. A total of 624 samples were collected. Total expenditures were $15,000.00.
In spring 2004, GeoTech Ltd. flew a high resolution VTEM geophysical survey over the Iron Range
property, centered roughly on the Iron Range Fault structure, with more detailed lines flown over the
inferred LMC. A total of 695 line km's was flown, covering 58.2 km2. The data was reprocessed and
interpreted by Condor Geophysics who identified a number of AdTau conductivity and magnetic
anomalies. During the summer of 2004, Eagle Plains collected 1062 soil geochemical samples and 8
silt samples targeting the area of the inferred LMC. Doug Anderson, P.Eng. was retained by Eagle
Plains to provide geological mapping in the area of the Lower Middle Aldridge (Sullivan Horizon).
Late in 2004, a diamond drill program was carried out to test the northern part of the main Iron Range
structure in the area of the historic Cominco trenches. Three holes on two sites were completed for a
total of 570.4 meters. The drill contractor was FB Drilling of Cranbrook, BC using a Longyear LF70
drill cutting NQ sized core. The drill was moved to the first site using an A Star helicopter provided by
Bighorn Helicopters of Cranbrook, BC. The drill was mounted on an enclosed skid shack and moved
using a D6 cat. Crews commuted to work from Creston via the Hall Lake FSR and the Iron Range
exploration trail established by Cominco in the 1950s. The total cost of the 2004 work was
$242,617.53.
Work at the Iron Range continued in 2005. Geochemical coverage was expanded to cover the
southwestern part of the property in an area of both geophysical AdTau enhancement and anomalous
soil geochemistry. A total of 1870 soils, 15 silts, and 3 rock samples were collected by Bootleg
Exploration field crews. Doug Anderson completed further geological mapping in the southwest area.
In late spring, Eagle Plains completed a four hole 1377 meter test of geological, geochemical and
geophysical targets in the area of the Lower Middle Aldridge contact. Three different sites were tested
using the FB Drilling Longyear LF 70 drill cutting NQ sized core. Drill moves and core haul were
helicopter supported using Bighorn Helicopters. The lower drill site was road accessible, and the two
upper sites were accessed via the CrackerJack Creek FSR and then by foot to the drill. The total cost of
the 2005 work was $282,532.99.
The 2008 diamond drilling exploration program focused the Union Jack, O-Ray, Keepsake, Rhodesia
and unnamed mineral occurrences located within the Iron Range Fault zone (IRF). The two primary
objectives of the drill program were as follows; 1) To test the IRF for prospective IOCG mineralization
and, 2) to define a near surface iron resource.
High-grade Au mineralization was intersected adjacent to the IRF at the O-Ray Minfile occurrence.
Assay results of the high-grade zone are as follows: 51.52 g/t Au, 2.39 g/t Ag over 7.00m; including
89.98 g/t Au, 4.17 g/t Ag over 4m; also including 118.45 g/t Au, 5.56 g/t Ag over 3.0m (IR08006). The
high-grade gold mineralization is hosted within a Chl-Alb-Mt-Hem-Lim metasomatic alteration halo
flanking the western margin of the IFR. Qtz-Hem-Chl-Fl-Ms+/-Py+/-Au+/-Ag crackle veinlets occur
as stockwork within the metasomatic alteration. Hydrothermal metasomatism and surficial weathering
have altered the high-grade interval to friable albite-limonite gouge.
The 2008 diamond drilling activities and related exploration on the Iron Range property resulted in a
total of $634,182.26 in expenditures.
The high grade gold intersection from 2008 formed the basis for a mapping, systematic channel, and
soil sampling program over a series of three east-west oriented trenches on the Iron Range iron oxide
structure within the historic O-Ray showing area in the summer of 2009. The program accommodated
ongoing academic studies through a joint collaboration of industry and university known as the
MITACS Accelerate Program. Masters student Michael Galicki continued field work for his thesis
titled: 'Geochronology and Petrology of Iron Oxide Mineralization, Creston, B.C'. and 'Paleomagnetism
of the Iron Range Iron Oxide Deposits'. Eagle Plains Resources Ltd. funded 50% of the work..
A joint venture agreement with Swift Resources Ltd. in the latter part of 2009 resulted in a seven hole
diamond drill program. A total of 579.17m of NQ2 size core were drilled at the O-Ray showing, with
the vast majority of drill holes vectored at intersecting the gold mineralization from the 2008 program.
Results of the program indicated structural controls on the gold mineralization at depth.
The total expenditures for the combined 2009 exploration programs amounted to $ 403,389.04
GEOLOGY
REGIONAL GEOLOGY
Overview
The Iron Range property is located on the west flank of the Purcell Anticlinorium, a broad generally
north-plunging structure in southeastern B.C. that is cored by Middle Proterozoic Purcell Supergroup
rocks and flanked by Upper Proterozoic Windermere Group or Paleozoic sedimentary rocks. The Iron
Range area is well to the west and in the hangingwall of the Moyie Fault, a major, regional right-lateral
reverse fault which to the east becomes part of the Rocky Mountain fold and thrust belt event. The
property does however straddle the Iron Range Fault (IRF) complex which consists of a number of
north-striking faults which occur across an east-west extent of about 3km. The core fault zone is
thought to link with the St. Mary-Hall Lake Fault systems about 30km to the north. The IFR cuts the
core of the Goat River anticline which is a major secondary fold on the west limb of the anticlinorium.
The IFR continues south into the United States and along its entire length as a mappable structure it is
marked by a linear magnetic anomaly on airborne surveys.
The rocks of the Goat River anticline are those of the Aldridge Formation which is the lowest part of
the Purcell Supergroup. The Purcell Supergroup comprises an early synrift succession, the Aldridge
Formation, and an overlying generally shallow water post-rift or rift fill sequence which includes the
Creston and Kitchener Formations and younger Purcell rocks.
The Aldridge is the oldest formation of the Proterozoic Belt-Purcell Supergroup. The Supergroup is a
thick sequence of terrigenous clastic, carbonate, and minor volcanic rocks of Middle Proterozoic age.
The basal Aldridge Formation, as exposed in Canada, consists of siliciclastic turbidites about 4000m
thick. It is informally divided into the Lower, Middle, and Upper members. To the north and east in
the basin, the Lower Aldridge (LA), the base of which is not exposed, is about 1500m of rusty
weathering (due to pyrrhotite), thin to medium bedded argillite, wacke and quartzitic wacke generally
interpreted as distal turbidites. The Sullivan ore body occurs at the top of this division. To the south
and west in the basin in Canada, the upper part of the Lower Aldridge is dominated by grey weathering,
medium to thick bedded quartz wackes considered to be proximal turbidites. The Lower Aldridge is
commonly host to a proliferation of Moyie intrusions, principally as sills. The Middle Aldridge (MA)
is about 2500m of grey to rusty weathering, dominantly medium bedded quartzitic wacke turbidites
with periodic inter-turbidite intervals of thin bedded, rusty weathering argillites some of which form
finely laminated marker beds (time stratigraphic units correlated over great distances within the
Aldridge/Prichard basin). There are several Moyie intrusions as sills within the Middle Aldridge
including two of the most consistent, laterally extensive sills. The Upper Aldridge is about 300m of
thin bedded to laminated, rusty weathering, dark argillite and grey siltite often in couplet-style beds.
Intrusive Rocks
Gabbros and diorites of the Moyie Intrusions are present as sills in the Ramparts facies and the Middle
Aldridge with individual widths up to approximately 100m. These sills can be divided into a lower
series in the Ramparts facies and lowermost Middle Aldridge, and an upper series in the uppermost
Middle Aldridge. Individual sills vary substantially in grain size, color and magnetic character
rendering correlation based on these characteristics problematic. Most of the sills are non-to weaklymagnetic, and rarely attract a hand magnet. Adjacent to some sill contacts, Aldridge Formation
sedimentary rocks record soft-sediment deformation features consistent with the interpretation that the
sills were emplaced into wet sediments. Gabbro is also found as pods within the Iron Range fault zone,
suggesting that gabbro was emplaced as a dyke along at least part of this structure (see below).
While granitoid intrusions are not found within the Iron Range map area, the exposed margin to the
Cretaceous Bayonnne batholith crops out approximately 10km to the northwest.
A polymictic lamprophyre breccia dyke with biotite phenocrysts up to 2cm is noted at one locale to be
emplaced along the IRF. The matrix to the lamprophyre breccia is non-foliated suggesting it was
emplaced late in the fault history.
Current studies by Mike Galicki, M.Sc., student of Simon Fraser University, are investigating the
presence of apatite-phlogopite-magnetite alkaline carbonatite intrusives found within and adjacent to
the IRF. Additionally, a number of samples of iron oxide were collected to infer an age date (s) for the
Iron Range structure based on paleomagnetism.
Structure
The IRF is exposed on the west limb of the Goat River anticline, a regional scale gently northnorthwest plunging fold. The trace of the fault trends approximately north, such that at the northern
end of the map area, the fault lies approximately 5km from the axial trace of the Goat River anticline,
while at the southern end of the property, the two are approximately coincident. As a consequence,
bedding in the northern half of the map area most commonly dips moderately to the west-northwest,
with subordinate beds on the eastern limbs of parasitic anticlines dipping to the east-southeast. The
southern half of the map area is approximately coincident with the axial trace of the Goat River
anticline, and bedding is nearly flat lying.
Although east-dipping fold limbs are poorly represented in the map area, an approximately 90° spread
in the orientation of east and west dipping fold limbs indicates that the Goat River anticline and
associated parasitic folds are open folds. The calculated orientation of the axial plane to regional folds
is 195/83 (west-northwest-dipping).
Fold axes to mesoscale folds exhibit shallow to moderate plunges to the north-northwest, that are
consistent with the calculated β axis orientation of 007/015. The approximately 30° spread in both the
plunge of measured and calculated fold axes and the spread in bedding measurements reflect a noncylindrical component to the regional fold hinges.
A regional foliation is best developed in fine grained siltstones and silty shales, most common in the
northern half of the map area. The mean orientation to this regional foliation is 196/61 (west-
northwest-dipping). Except where measured along the axial plane of mesoscale parasitic folds, this
foliation has a more shallow dip than the calculated axial plane to the Goat River anticline (195/83).
This difference can be explained by the common observation that the moderately dipping regional
foliation in fine grained lithologies refracts across coarser grained lithologies to form a sub-vertical
fracture cleavage. Thus, while the regional foliation is not typically axial planar to regional folds it is a
product of the folding event.
Property Geology
Overview
The Iron Range deposits are located along the IRF system, a regional structural feature which has a
strike length of at least 90km. The fault zone forms a continuous deformation corridor stretching from
the southern to northern ends of the property. Stinson and Brown (1995) note that a southern
continuation of the fault is exposed 1.5km southeast of Mt Thompson, where it forms an anastomosing
set of faults. To the north of the map area the IRF is cut by the Arrow Creek thrust system (Reesor,
1981).
Within the claim block the IRF is defined by several north-striking faults which cut all three
stratigraphic divisions of the Aldridge Formation. The trace of the fault trends approximately north,
such that at the northern end of the map area, the fault lies approximately 5km from the axial trace of
the Goat River anticline, while at the southern end of the property, the two are approximately
coincident. The northern part of the property was mapped by Marshall in 2001. Here, the IRF zone
ranges in width from <50m to approximately 150m. Net displacement is difficult to constrain due to
the lack of distinct stratigraphic horizons, but appears to be minor, based on the apparent offset of a sill
in the central portion of the 2001 map area. The fault zone is characterized by a combination of brittle
and ductile features, including a central mylonite zone with localized cataclastic breccias. This grades
outwards in both the footwall and hangingwall into zones of crackle brecciation, veining and localized
shearing. The structural features preserved in the fault indicate at least one period of deformation after
the sediments were lithified, and after crystallization of the Moyie Intrusions. Further, crackle breccias
in the fault zone are not overprinted by the regional foliation, suggesting that at least some deformation
along the Iron range fault zone occurred late to post folding and regional foliation development. The
range of preserved deformation styles suggests deformation occurred near the elastico-frictional to
quasi-plastic transition described by Sibson (1977), which typically occurs at a depth between 10 and
15km.
The shear fabric developed within the fault zone has a mean orientation of 178°/77° (west-dipping) and
variation in strike of individual measurements between approximately 160° and 200° reflects
anastomosing of the shear fabric within the fault zone. Given the correlation between the mean
orientation of the measured shear fabric, and the mapped orientation of the fault, the mean shear fabric
is taken as a good approximation of the fault orientation. In the northern half of the map area, the shear
fabric has a mean orientation of 181°/76° (west dipping) while in the southern half the mean orientation
is 168°/85° (west dipping).
Drag folding of both sediments and gabbroic sills is noted in both the footwall and hangingwall to the
fault. Bedding measurements on both sides of the fault exhibit a consistent shift towards more steeply
west dipping orientations as the fault is approached. This suggests predominantly normal displacement
on the fault during at least one ductile (or brittle-ductile) slip event. The occurrence of rare pull-apart
structures within banded hematite-quartz mylonite also suggests normal displacement.
Mapping during 2004 - 2005 focused on a 40km2 area on the southern end of the Iron Range property
north of Highway 3/95 between the Goat River on the east and Arrow Creek on the west. Mapping was
done at a scale of 1:10,000 with a generally low percentage of outcrops encountered. The 2004 - 2005
mapping area covers the core of the Goat River anticline reaching significant portions of the limbs on
the east and west. Mapping defined the most significant features as the north-trending, numerous faults
and the features associated with them. The core of the anticline corresponds to the core of the IRF
complex as well. Here, at least three parallel faults occur across 1250m east-west. The faults exhibit
moderate displacement of the Sullivan Horizon. The structural zone has also influenced the
emplacement of Moyie intrusions as dykes and sills, focused hematite and magnetite mineralization
and associated albite and chlorite alteration within tectonic brecciation, the development of localized
sedimentary fragmental formation, and the development of the Sullivan Horizon and bounding
sedimentation.
These growth faults, active during the early Proterozoic are also re-activated structures (probably at
several different times) at least to the middle of Middle Aldridge time. There are several other northstriking faults on the map-sheet. One fault on the east side of the property also appears to control
features such as sill and dyke emplacement, albite/chlorite alteration and sedimentary fragmental
formation. It appears to cut close to the axis of an anticlinal fold on the east limb of the Goat River
structure. On the west side, a NNE trending fault influenced the same type of developments as for
other faults. The west side of this structure is not well defined because of a lack of outcrop.
This complex of structures has impacted the Aldridge Formation host rocks and the included Moyie
intrusions. The oldest sedimentary rocks are Lower Aldridge encountered at the very base of outcrop
along the north flank of the Goat River. The thickness of rusty weathering, thin bedded, argillaceous,
distal turbidites is limited, quickly becoming dominated by thick bedded quartzites of the Ramparts
Facies up section. Ramparts Facies is a Lower Aldridge equivalent section of about 650m thickness
which defines upper Lower Aldridge in the southwest part of the Canadian portion of the Purcell basin.
Ramparts Facies is represented by grey weathering, thick to very thick bedded, fine to medium grained
quartz wacke to quartzitic wacke. There are interbedded argillaceous units which approximate 5 to
15% of the section. These are current impacted, often dark colored, biotitic wacke to argillite.
Ramparts Facies are proximal turbidites, rapidly deposited in a high energy environment. Intruding the
Lower Aldridge and Ramparts Facies are numerous Moyie intrusions as sills and dykes of variably
crystalline gabbro to quartz diorite. On the east side, granofels was noted in the lower sill intruding
Rampart Facies rocks.
Above the Ramparts Facies-Lower Aldridge transition are Middle Aldridge sediments exemplified by
moderately rusty weathering, interbedded AE or ACE Bouma facies turbidites which are dominantly
medium bedded quartzwacke with intervals of thin bedded to laminated argillaceous wackes.
Stratigraphic marker horizons exist within this portion of the Middle Aldridge and one such marker was
located on the northeast portion of the map sheet. The marker provides some measure of stratigraphic
control on the entire section of Middle Aldridge through Ramparts Facies to Lower Aldridge. Moyie
intrusions are present as dykes and sills as relatively minor units. Major, regionally extensive sills
occur higher in the Middle Aldridge, north of the map area and in the soutwest portion of the claim
block. The latter form a volumetrically large assemblage intercalated within the Ramparts Facies
primarily west of the main IRF. The assemblage lies within an area of approximately 40km2, extending
into the equivalent Belt rocks in the United States.
The Lower/Middle Aldridge Contact or Sullivan Time is present on the property and occurs at the
interface between Ramparts Facies and the Middle Aldridge. Moderate to poor outcrop exposure limits
views of the Sullivan Horizon across the property.
In 2005, emphasis was given to field examination of the west side along the NNE trending fault zone as
further modeling of the airborne geophysics data indicates an EM conductor occurs at a shallow depth.
The west-facing slope into Arrow Creek has little exposure but outcrops in the area suggest some
variations from the normal Middle Aldridge rock sequence. Black argillites and quartzites in the area
of the anomaly suggest an anoxic sub-basin may be present. As well, tourmaline is ubiquitous as minor
disseminations in the sediments. Some float over the north-central part of the anomaly is black, quartzrich rock matrix to charcoal grey carbonaceous clasts as fragmental. The NNE fault appears to project
through and impact the shape of the EM response.
Mineralization in the map area prior to drilling is represented primarily by the hematite-magnetite
zones within the core fault complex of the Iron Range. They are cross-cutting, often breccia zones
within the gabbro dominated section. The main focus of the 2005 mapping was to evaluate the
possibility of base-metal sulphide mineralization occurring at Sullivan Time. Presently known sulphide
showings occur as cross-cutting copper, lead, and zinc veins localized within Moyie intrusions. There
is also the upper sill on the east side which contains abundant pyrrhotite locally, some of which is
nickeliferous. No additional (new) sulphide occurrences were located as a consequence of the
mapping.
Early fault history
In the northern half of the map area, the IRF lies predominantly on the west-dipping limb of the Goat
River anticline, which has a mean orientation of approximately 210°/30°. By unfolding this limb to
horizontal about the regional fold axis, the original orientation of the IRF in the northern half of the
map area is shown to have been approximately 170°/50° (west-dipping). In the southern half of the
map area the fault cuts near flat-lying stratigraphy, and as such the current orientation of the fault of
approximately 170°/85° (west-dipping) is close to the original orientation.
Other fault zones
A broad zone of weak crackle brecciation and albitization striking approximately 035° with a near
vertical dip marks the Black Bear fault. The fault zone is poorly exposed, and timing, sense and
magnitude of displacement remain unconstrained. The projected intersection between the Black Bear
fault and the Iron Range was the target for DDH IR04-003.
An inferred fault marks the apparent 1100m stratigraphic offset of a sill to the east of the Iron Range
fault in the northern half of the map area, and is here named the Alder fault. The Alder fault is not
exposed, and it remains uncertain as to whether the apparent offset is a result of the intrusion cutting
upsection during emplacement along a growth fault, tectonic displacement, or a combination of the
two. The projected intersection of the Alder fault and the IRF was the target for DDH IR04-001 and
002.
The Crackerjack fault is described by Stinson and Brown (1995) as a narrow fault zone trending
approximately parallel to and east of the IRF. The Crackerjack fault is marked by a zone
approximately 10m wide of crackle to mosaic brecciation within Middle Aldridge quartzite. It remains
uncertain if and where the Crackerjack and IRF intersect.
The Talon zone fault is a N-NE trending zone approximately 30m wide. It occurs 450m west of the
Iron Range fault and courses the Lower-Middle Aldridge contact. The Talon fault is a silica-sericiteminor albite alteration zone which hosts precious and base metal mineralization, as discovered in the
2010 drill campaign. The fault is discussed in detail within the 2010-2011 Exploration Program
section.
Moyie Sills
The nature of the gabbroic Moyie sills within and adjacent to the IRF remains enigmatic. Pods of
gabbro occur along the IFR zone at stratigraphic positions where sills are absent in regions of the BeltPurcell Supergroup of similar age. In addition, sills placed in structural juxtaposition across the fault
zone are not stratigraphically coincident. Furthermore, gabbros are anomalously thick and abundant in
the vicinity of the Iron Range fault. The Moyie intrusives are widely accepted as having been
emplaced into unconsolidated sediments deposited during syn-rifting tectonism.
Alteration
The following descriptions serve to place order to the complex mosaic of hydrothermal and regional
metamorphic alteration within and adjacent to the IFRZ. Alteration terms adopted from L. Corriveau, P.
Williams, H. Mumin, 2008.
Chlorite1
Occurs as regional metamorphic alteration within the Middle Aldridge, observed distal
to the IRF.
Chlorite2
Occurs with albite and magnetite as psuedo-igneous intrusions enveloping the IRF
((Ca(Na)Fe) or Chlorite + Albite Zone). The Chlorite + Albite zone is found at the
margins of the IRF in the “Crackle Breccia Zone”
Chlorite3
Occurs as clots and wisps with in IRF breccias.

mineralization. White to rose in color.
Albite3
Occurs with chlorite and magnetite as psuedo-igneous intrusions enveloping the IRF
((Ca(Na)Fe) or Chlorite + Albite Zone). The Chlorite + Albite zone is found at the
margins of the IRF in the “Crackle Breccia Zone”.
Hematite1
Specular hematite as fine grained disseminations and fracture fill crackle veins within
the Na(Ca) and Ca(Na)Fe zones. Dusty gray to black in color.
Hematite2
Semi-massive growth of hematite within the IRF breccias. Occurs as breccia matrix.
Often inter grown with pyrite. Blood red to black in color.
Hematite3
Fracture fill veinlets associated with sericite alteration. Red to purple in color.
Magnetite1
Semi-massive to massive growth as primary cement within IRF breccias. Often
overprinted by pyrite mineralization. Near surface mineralization is vuggy, primarily
black in color.
Magnetite2
Euhedral crystals ranging in size from 2 – 10mm, within carbonatite intrusions.

Carbonate2
Carbonate matrix – carbonatite intrusions.
Argillic-Clay Intense alteration of the Middle Aldridge within and flanking the IRF. Orange-yellow in
color, hardness < 2.
IFRZ Breccia Styles
The IRF is characterized by a combination of brittle and ductile features, including a central mylonite
zone with localized cataclastic breccias. This grades outwards in both the footwall and hangingwall
into zones of crackle brecciation, veining and localized shearing. The following breccia descriptions
highlight the textural variations.
Crackle Breccia – Albite-chlorite-sericite-hematite mottled, sub-angular to angular framework clasts
suspended in a matrix of quartz +/- hematite +/- magnetite +/- pyrite crackle veins. Crackle breccias
are found peripheral to the IRF core complex. Framework clasts are strongly altered and may be whiteorange-greenish-yellow in color. Hematite is disseminated through the framework clasts.
Jigsaw Breccia – Albite framework clasts containing disseminated pyrite within a matrix of Fe-Oxide
(specular hematite > magnetite) and quartz. Classified as a tectonic crackle breccia, often displaying
cataclastic fabrics. Located in the core of the IRF complex. The name “jigsaw breccia” is derived
from the angular nature of the framework clasts. Framework clasts are white-pink in color.
Tectonic Breccia – Hematite +/- Magnetite +/- Pyrite +/- Albite +/- Quartz +/- Chlorite +/- Carbonate
breccia. Fe-Oxide and quartz are the primary cement, with chlorite and carbonate as secondary phases.
Tectonic breccias were classified upon the presence of heterolithic framework clasts in conjunction
with a pronounced cataclastic-mylonitic fabric.
Late-stage Breccia – Cross-cutting tectonic features characterized by sub-angular to rounded Fe-oxidepyrite-chlorite-albite framework clasts in a silica matrix. These features are prominent at the Rhodesia
Minfile occurrence.
Mineralization
Mineralization is represented in part by hematite-magnetite-pyrite-quartz-albite breccias within the core
fault complex of the IRF. The following text will provide insight into the nature of the breccias
observed during 2008 within the IRF, and 2010-2011 drill programs related to the Talon zone.
IRF Oxide Zone Breccia – Generated from meteoric groundwater interaction or hydrothermal
processes. Fe-oxides occur as jet black, semi-massive to massive, vuggy magnetite mottled with
reddish-brown specular hematite. Pyrite mineralization is leached from the interval. The leaching
process has produced sub-angular to sub-rounded vugs ranging in size from 2 – 30mm. In some
instances the weathered vugs are enveloped by a chlorite-magnetite matrix. Wall rock in contact with
the leached Fe-Oxides displays strong limonitic alteration, and is some instances is reduced to an
argillic clay gouge.
Talon Zone Oxide Breccia - Road exposure through logging development revealed a vuggy, limonitic
oxide breccia zone in the south-centrally located Talon zone. This zone lacks the iron oxide form of
magnetite and specular hematite of the IRF, showing remnant boxwork textures from pyrite and
secondary iron oxide leaching. Pyrolusite and limonite characterizes the exposure with liesgangue
textures displayed in the core to depths up to 100m. The zone displays an internal cataclastic fabric
flanked by lesser spaced N-NE trending cleavage, with a steep westerly dip. The orientation and
attitude controls the Au-Ag-Pb-Zn mineralization encountered in the 2010-2011 drill program.
IRF Hematite +/- Magnetite +/- Pyrite +/- Quartz +/- Albite +/- Chlorite +/- Carbonate +/Chalcopyrite Breccia – Characterized by semi-massive to massive hematite (specularite to blood red
amphorous variety) +/- pyrite replacing magnetite. Quartz occurs as the primary cement, with ankerite,
sericite, chlorite, and muscovite as secondary accessory phases. Framework clasts consist of albitized
meta-sediments, silica, chlorite, and ankerite nodules. Albite framework clasts are commonly found at
the margins of the tectonic breccias and/or within siliceous bands of breccia matrix. Pyrite
mineralization is common along the IRF, and occurs disseminated through albite framework clasts and
Fe-oxide-silica matrix.
Talon Zone Sericite +/- Silica +/- Carbonate +/- Pyrite +/- Chlorite +/- Albite Breccia – The Talon
zone forms an elongate sericitic alteration halo approaching 50m in width along a NNE trend.
Internally alteration is progressively intense with a silicic overprint which is texture destructive.
Silicification is uppermost in cataclastite fabric and variably associated with hydrothermal carbonate
(dolomitic) veinlets commonly in association with sulphide development, which is dominated by
pyrite. Chlorite and sericite persist subordinately to the pervasive silicic phase, with albite less
common. Brecciation is seen as localized zones or extensively over 10's of metres.
Mineralization of Economic Importance:
Copper and/or gold, and/or silver and/or lead and/or zinc mineralization have been discovered in at
least eight locations adjacent to, and within the IFR over a distance of 11.6km. From south to north
seven of these showings/zones are as follows: May-Bee (Au-Ag-Cu), Talon (Au-Ag-Pb-Zn), Rhodesia
(Ag), Keepsake (Ag), O-Ray (Au-Ag), Union Jack (Cu) and M-Kennedy (Cu-Au-Ag) (Figure X).
The principle copper mineral within the IRF probably associated with Moyie intrusions is chalcopyrite.
Chalcopyrite occurs as macroscopic grains and nodules within quartz and ankerite veins. The
relationship between the Cu +/- Au +/- Ag quartz veins and the Fe-oxide breccias of the IRF is still
unclear. Of significance is the 2008 discovery of chalcopyrite as fine disseminations within Fe-oxide
breccia style mineralization 200m below the Union Jack showing. Chalcopyrite mineralization in DDH
IR08018 occurs within a hematite-magnetite-pyrite-quartz-albite-chlorite-carbonate breccia.
Chalcopyrite mineralization is disseminated throughout the Fe-oxide mineralization at the foot wall
contact and within ankerite crackle veins cross-cutting the interval. Copper mineralization within the
Talon zone is realized within minor occurrences of the suphosalts bournonite and tetrahedrite and rare
to minor occurrences of disseminated chalcopyrite.
Native gold within DDH IR08-006 at the O-Ray showing occurs in quartz as coarse flakes > 140
microns, with a lesser fraction of fine gold < 140 microns. Gold particle size was determined by a
250g screen metallic assay method, performed by Eco Tech. The principle mineral containing silver
mineralization is undetermined at the present time. The high grade Au-Ag intercept occurs in a
strongly altered shear zone found adjacent to the IRF Fe-oxide breccias. The shear zone is sub-vertical
and occurs as a series of quartz stockwork veins within friable albite, chlorite, and limonite altered
meta-sediments. Fluorite, pyrite, hematite, magnetite, and chlorite were observed within quartz
recovered from the high grade gold zone. The high grade Ag intercept found in the hanging wall of the
Keepsake zone is of similar width, orientation, and displays alteration characteristic of the O-Ray AuAg zone. Although no Au results were obtained from the Keepsake zone, the anomalous Ag values
indicate the presence of mineralized fluids within the system. The relationship between Au-Ag
mineralization is still unclear, however it is apparent that both of the metals can occur together as
observed at the May-Bee, O-Ray and M-Kennedy showings as well as in DDH IR05003. Anomalous
Ag mineralization found at the Rhodesia zone occurs within quart-magnetite-hematite-pyrite crackle
veins hosted by chlorite-albite-carbonate-hematite metasomatic alteration.
Cu-Au-Ag-Pb-Zn
mineralization observed in the M-Kennedy and May-Bee zones occurs as polymetallic quartz veins
within diorite-gabbro sills or dykes. These veins range in size from 0.3-2.0m in width. Of interest is
the reported observation of a lamprophyre dyke adjacent to the mineralized veins of the May-Bee zone.
Field reconnaissance is necessary to confirm the observation.
Significant gold values within drill core from the Talon zone is shown to be intimately associated with
arsenopyrite as micron sized gold grains. The arsenopyrite typically occurs as very fine disseminations
which render siliceous breccias and veinlets a drusy gray, or as very fine subhedral to euhedral
crystals. Silver is related to sulphosalts which have been identified macroscopically as jamesonite,
polybasite and minor pyrargyrite. Lead is developed within semi-massive to massive veins and
veinlets of galena, and to a minor degree within the sulphosalts jamesonite and bournonite. Zinc is in
association with sphalerite which is commonly manifested in veins and veinlets typically associated
with galena as pale red to locally red-brown clots. It is variably noted as very fine to fine subhedraleuhedral disseminations in sections of pervasive silicic alteration and brecciation.
2011 PHASE III EXPLORATION PROGRAM
This report deals with the soil sampling, geophysical surveys and mapping initiatives conducted on the
Iron Range property during 2011. The program has been separated into four phases with Phase I and II
specific to drilling and discussed in a separate report. Phase III consists of soil sampling, mapping,
induced polarization ground and downhole geophysics, airborne geophysics and geological mapping.
Phase IV is the next stage of drilling planned for the Iron Range property.
Surface and Borehole IP (Volume II, Appendix I)
Surface and borehole Induced polarization (IP) and surface total field magnetometer surveys were performed at the Iron Range Project, Creston area, B.C. within the period May14-25, 2011. In addition,
non-differential GPS readings were taken at each surface current and potential electrode location, subject to satellite reception. The survey was performed by Scott Geophysics Ltd. on behalf of TerraLogic
Exploration Services.
Surface survey
The pole-dipole array was used. Readings were taken with an “a” spacing of 50m and at “n” separations of 1 to 12. The on line current electrode was located to the east of the potential electrodes.
Total field magnetometer readings were taken at 12.5m intervals and corrected for diurnal variation
against a fixed base station cycling at 10 second intervals.
GPS readings were taken at each station subject to satellite reception. Elevation measurements are barometric altimeter readings, calibrated to GPS altitude at the beginning of each line.
A total of 3.8km of surface IP and magnetometer survey were performed.
Borehole survey
The survey was performed with directional and detail arrays. For the directional array, current electrodes were located near the collar, and 300m to the north, east, south, and west of the collar. Reading
were taken between each set of electrodes and a common remote electrode. In addition, readings were
taken between adjacent pairs of directional electrodes. For each electrode configuration, borehole axial
gradient measurements were taken at 5m intervals with an “a” spacing of 10m. The detail array used
the pole-pole array with “a” spacing's of 2.5m and 5.0m
The surface chargeability and resistivity results are presented on the accompanying pseudosections and
triangular-filtered plan maps. The borehole chargeability and resistivity results are presented on the
accompanying profiles. The magnetometer survey results are presented on the accompanying profiles
and plan maps. This data can be found in Volume II, Appendix I.
Soil Sampling Program (Volume II, Appendices III-IV)
4245 soil samples were taken in 2011 over six areas: Arrow East (grid and contour), Row (grid),
Canyon (grid), Canyon East (grid and contour), Gap (grid) and 6 Mile (grid). Details regarding
sample collection, location, description and processing can be found in Volume II Appendix II.
Approximately 35% of the soil samples were sent to Stewart Group in Kamloops, B.C. In the late
summer of 2011 Stewart Group was acquired by ALS Group, and so the rest of the samples from the
program were sent to ALS Chemex in Vancouver for processing. The sampling and processing
methods for both labs are described in detail in Volume II Appendix II.
What follows below is a brief description of the results from the 2011 soil sampling program separated
by area (see Figures 5-10).
Arrow East (Fig. 6a/b)
The Arrow East area is located NE of the Row showing covering several showings located along the
IFR. A number of linear N-S trending Pb-Zn anomalies occur in the area associated with the main IFR
structure as well as parallel structures. Several spotty isolated Cu anomalies are also present and
appear to correspond spatially with gabbro bodies.
Canyon (Fig. 7a/b)
The Canyon grid covers the area between the Talon and Niagara showings. A number of interesting
anomalies occur on this grid including discrete linear Au anomalies that appear to trend NE-SW, E-W
and NW, particularly observable approximately 750m north of the Talon showing. These Au trends
correspond reasonably well with As anomalies, although strong As anomalies may not have a strong Au
expression. Some of the Au values also correspond to elevated Zn +/- Pb +/- Cu values. The primary
trend of the Talon showing (NE) is best observed by looking at the Zn values.
6 Mile (Fig. 8a/b)
The 6 Mile area is located between the Niagara and Pacific showings. Anomalous Zn values occur in
the northern part of the grid SE of the Pacific showing.
Canyon East (Fig. 9a/b)
The Canyon East grid is located between the Canyon and Gap grids. A few spotty Cu-Zn anomalies are
present in the southern and central part of the grid. Two prominent Zn-Pb +/- As anomalies occur in
the northern part of the grid area at the NE strike extension of the main Canyon anomaly; however;
they both have a clear NW trend.
Gap (Fig. 9a/b)
The Gap grid is located east of the Canyon East grid. The area shows a weak Zn-As anomaly in the
northern part of the grid. The trend is not clear, but may be oriented roughly NE. A small Cu anomaly
is also present in the SE part of the grid.
Row (Fig. 10a/b)
A strong NNE trending Pb-Zu-Cu +/- As anomaly occurs in the eastern part of Row, originally
discovered in 1986. The following discussion is based on the results from the 1986 survey as well as
the 2011 soil sampling. The anomaly has been traced for approximately 3.5km and ranges from 300-
500m in width. It occurs approximately 500m west of where the Arrow Fault has been mapped, which
trends in the same direction as the anomaly. Thus, there is a reasonable chance the two are related.
A second smaller anomaly occurs to the west of the main one, also trending NNE and corresponding
well with a mapped fault.
In addition to the two main anomalies, there appears to be a couple of weakly defined Pb-Zn-Cu
anomalies trending E-W to WNW-ESE. There is also a rather significant blob-shaped Cu anomaly in
the extreme SW of the grid area.
VTEM-ZTEM & AGG Airborne Surveys
Reports detailing the results from these three airborne surveys can be found in Volume III Appendixes
II-III. Below is a summary of each of the programs.
VTEM Airborne Survey (Volume III, Appendix II)
On October 16th – 17th, 2011 Geotech Ltd. carried out a helicopter-borne geophysical survey over the
Row Block situated approximately 56km southeast of Crawford Bay, British Columbia and 4km east of
Wynndel, British Columbia.
Principal geophysical sensors included a versatile time domain electromagnetic (VTEM plus) system,
and a caesium magnetometer. Ancillary equipment included a GPS navigation system and a radar altimeter.
In-field data quality assurance and preliminary processing were carried out on a daily basis during the
acquisition phase. Preliminary and final data processing, including generation of final digital data and
map products were undertaken from the office of Geotech Ltd. in Aurora, Ontario.
The total area coverage is 50 km2. Total survey line coverage is 287.5 line kilometres. The principal
sensors included a Time Domain EM system and a magnetometer.
Based on the geophysical results obtained, the area has 4 conductive zones (Figure 8; in report entitled
'Report on a helicopter-borne versatile time domain electromagnetic (VTEM plus) and aeromagnetic geophysical survey'; Volume III, Appendix II) of low to very low conductance. The zone marked as #1 in Figure 8
is powerlines.
Conductive zone #2 in Figure 8 is low conductor and it is oriented SW-NE. The zone is associated with
magnetic contact on the area.
A small zone #3 is a very low conductor and it is associated with the magnetic contact of the area.
Near surface zone #4 is a very low conductor that is associated with the magnetic contact of the area.
This is possibly conductive overburden or a layer of conductive surface rock.
ZTEM Airborne Survey (Volume III, Appendix II)
During September 13th to 14th 2011 Geotech Ltd. carried out a helicopter-borne geophysical survey for
TerraLogic Exploration Services over Talon Zone Orientation block situated 10km northeast of
Creston, British Columbia.
Principal geophysical sensors included a Z-Axis Tipper electromagnetic (ZTEM) system, and a caesium magnetometer. Ancillary equipment included a GPS navigation system and a radar altimeter. A
total of 160 line kilometres of geophysical data were acquired during the survey.
The survey operations were based out of Creston, British Columbia. In-field data quality assurance and
preliminary processing were carried out on a daily basis during the acquisition phase. Preliminary and
final data processing, including generation of final digital data and map products were undertaken from
the office of Geotech Ltd. in Aurora, Ontario.
Geotech Ltd. concluded the following:
Based on the geophysical results obtained, a number of interesting conductive structures were
identified across the property. The magnetic results also contain worthwhile information in support of
exploration targets of interest. We therefore recommend a more detailed interpretation of the available
geophysical data, including additional 2D or 3D inversion in conjunction with the geology, prior to
ground follow up and drill testing.
As a result, TerraLogic secured the services of Condor Consulting Inc. to conduct a more detailed
interpretation of the data. The results of this interpretation were not available to the current author at
the time this report was written.
AGG Airborne Survey (Volume III, Appendix III)
Details of the AGG survey are outlined in Appendix A. As with the VTEM and ZTEM data, additional
data processing is required before any major conclusions can be drawn.
Mapping Program
Mapping during the 2011 program focussed on the area underlying and proximal to the Canyon grid
(Figure 11). Among other things, the program accomplished the following:
1) Refined the location of the Lower-Middle Aldridge contact on the property.
2) Shifted the location and expanded the size of a large gabbro sill in the mapping area.
3) Located a stratigraphic marker horizon (the 'Kid') which was not known to exist on the property
prior to the mapping program.
Additional details regarding the mapping program can be found in Volume 2, Appendix 5.
CONCLUSIONS
Exploration on the Iron Range property to date has revealed a number of precious and base metal
showings. Most of these showings are spatially related to the IRF or to nearby parallel and subsidiary
splay structures. Two of the more prospective areas include: 1) the Canyon area which includes the
Talon showing and Au-Pb-Zn-As anomalies to the north. A number of variably striking structures
appear to be present which likely control the distribution of Au mineralization. 2010-2011 drilling has
shown there are wide intervals of low-moderate grade gold mineralization punctuated by smaller zones
of higher grade mineralization. While the linear nature of the soil anomalies suggests a primary
structural control, vein angles to core axis in the drillcore seem to point toward either a breccia system
flanking a structure with veins at random angles, or a vein array system; 2) the Row area, where a wide
N-S striking base metal anomaly occurs over a km-scale strike length. Importantly, the area has not
been drill tested to date.
In the authors opinion, the various geochemical, drilling and geophysics programs on the
property have helped to significantly advance the properties status by upgrading information from
known showings and locating new prospective areas worthy of further exploration. While the current
author has no serious concerns regarding exploration on the property, coarse gold at at least one
location on the property (the O-Ray showing) will require special consideration should it be
encountered elsewhere on the property.
RECOMMENDATIONS
The following program is recommended for the Iron Range property. The program should include
3000m of diamond drilling to test the Row anomaly in the western part of the Property. The estimated
costs for this program are shown below in Table 2.
