The key deposits and exploration targets within the Property are: Bonanza Ledge (an
advanced property that completed phase one test mining under small mines permit provision
with the Province of British Columbia; Cow Mountain; an exploration property for which a
Mineral Resource update is disclosed in this Report as a result of the completion of the reassay work program outlined in the previous technical report (Geoex, Apex, Snowden 2012);
and exploration targets at contiguous Island Mountain, Cow Mountain, and Barkerville
Mountain.
It is the intention of BGM to continue advancing the Cow Mountain project. The next
objective for BGM is to complete a Preliminary Economic Assessment (“PEA”) on the Cow
Mountain property.
This updated Report has been prepared by Mr. Walter Dzick, P.Geo., MAusIMM, APEGBC,
(QP).
For the Cow Mountain resource estimate update, an estimation approach similar to the one
applied in the previous estimate was used but with estimation parameters reviewed and
modified to reflect changes resulting from the incorporation of new data. This estimate is to
report resources for potential open pit extraction.
At Cow Mountain the current geologic interpretation of the mineralization is that it lies within
the Rainbow Unit and extends from the hangingwall to the footwall of the Rainbow Unit. The
2014 drill program tested the mineralization within the footwall of the Rainbow Unit. The
mineralization within the Rainbow Unit at Cow Mountain occurs in a complex framework of
widespread small scale quartz veins and veinlets that trend in a generally northerly direction,
as well as semi-massive to massive pyrite replacement zones which occur along the contact
of the Baker Rainbow units (hangingwall) and the Lowhee Unit (footwall). Snowden therefore
elected to apply a mineralization indicator modelling approach in order to identify mineralized
zones in a 3D block model.
All data was composited to equal sample lengths of 5 ft prior to statistical analysis and grade
estimation. This length was chosen as the majority of sample intervals (75%) were 5 ft length
or less. Declustering of the composite data was tested and the results indicated that the issue
of clustering did not have any significant impact, except for the mineralization indicator. All
statistics were therefore reported based on the composite file without declustering.

The gold grades within the mineralized domain were estimated with a modified Multiple
Indicator Kriging (MIK) approach. Snowden used an indicator approach to define the
proportion of mineralized material within the blocks. The grade in the mineralized proportion
was then estimated using MIK and the total mean grade within the block was estimated using
the average gold grade weighted by proportions. The density was assigned at 2.7 t/m3.
Grade estimates and models were validated by: undertaking global grade comparisons with
the input drillhole composites; visual validation of the block model in cross sections; and by
grade trend plots. To identify over-smoothing the Indicated Resources were compared with
the grade tonnage curves obtained with global change of support. The estimate validated
fairly well.
The resource classification definitions (Indicated and Inferred) used for this estimate are
those published by the Canadian Institute of Mining, Metallurgy and Petroleum in their
document “CIM Definition Standards”.
Classification was applied based on geological confidence, data quality and grade variability.
Other considerations for the classification were the historical underground mining within the
mineralized domain, with presence of large stopes; and the completion of a large re-assay
campaign for Cow Mountain drillholes from 1972 to 2011.
Areas classified as Indicated Resources are informed by the first search pass in the
estimation. The remainder estimated with the first or second pass was classified as Inferred
Resources. Areas where there is no informing data or only containing isolated drillholes are
not classified as a part of the Mineral Resource.
Mineral Resource estimates are currently reported for Cow Mountain in Table 1.3.

Property description and ownership
BGM, formerly known as International Wayside Gold Mines Ltd. (“WGM”), has been active in
the Cariboo Mining District of British Columbia since 1994 and has gradually put together a
large package of land that covers a majority of the historic gold mining properties that occur
along the Barkerville Gold Belt, near Wells in central BC. From Wells, the Property extends
22 miles to the SE, and 16 miles to the NW along the Belt (Figure 4.1). The QR claims and
mining lease identified in Figure 4.1 are located separately to the Property and hence data
and information for these are not disclosed in this Report.
.Final

Barkerville Gold Mines Ltd.: Cow Mountain NI43-101 Technical Report
Cariboo Gold Project
The Property is comprised of staked mineral tenures and Crown-granted mineral claims
covering an area of 454.5 square miles along a strike length of 38 miles and with an
approximate width of 12 miles. Since the last filed technical report (Geoex, Apex, Snowden
2012), BGM has staked 3 (three) mineral claim groups within the Property area, bringing the
total land package to its present size of 454.5 square miles or 117,714.97 hectares. Within
the Property there are still several legacy claims belonging to other persons or companies
which have first right to the mineral contained within those boundaries. Should those legacy
claims lapse, then the mineral rights will immediately belong to BGM as per the Mineral
Tenure Act. None of these legacy claims encumber the immediate project area of Island,
Cow or Barkerville mountains, subject of this Report. There are also a number of active
Crown-granted mineral claims and F-Grants which encumber the Property. These claims
have first rights to certain minerals along with other possible rights as outlined in the original
titles which were granted under the Land Act up to 140 years ago. While some groups of
these Crown-granted mineral claims are found on or immediately adjacent to Island, Cow and
Barkerville mountains, none of these Crown-granted mineral claims encumber or have any
impact on the Mineral Resources that are subject of this Report.
The Company has assured Snowden that all of the underlying agreements relating to the
mineral tenures and Crown-granted claims are valid and that all their mineral tenures are up
to date in terms of annual expenditure requirements.
The Company has assured Snowden that there are no royalties or other payments required
to be paid on the Island Mountain-Cow Mountain-Barkerville Mountain areas of the Property
that underlie the Mineral Resources and exploration targets that are the subject of this Report
other than the Myrtle Property which was acquired in the summer of 2011 and has a 3% Net
Smelter Return (“NSR”). The Myrtle Property is located on the summit and southwest flank of
Barkerville Mountain above the Barkerville Historic Town. There are, however, several claim
groups which are subject to net smelter royalties but in areas beyond the Island MountainCow Mountain-Barkerville Mountain areas of the Property as outlined in Section 4.3.
Annual expenditures to retain all of the mineral tenements in good standing are
approximately $2,350,000. The Company has sufficient expenditure accrued to maintain the
mineral tenements in good standing until 2020. As the claims are contiguous, except for one
small claim at present, the allowable assessment expenditure may be anywhere on the
Property and spread to cover the annual requirements of the whole Cariboo Gold Property.
1.3
Geology and mineralization
The Property is underlain by the Barkerville Terrane which is a late Proterozoic and/or early
Paleozoic sequence of metamorphosed rocks that were deposited as continental shelf to
slope marine clastic rocks along with lesser amounts of marine carbonate rocks and volcanic
rocks adjacent to the craton of ancestral North America.
During the Cretaceous the rocks of the Barkerville Terrane were deep below the surface and
subjected to an early period of ductile deformation that resulted in asymmetrical, overturned,
isoclinally (both limbs and the axial planes dipping to the east) folded structures with the fold
axes plunging shallow to the northwest. Major regional thrust faults, initiated in the post
metamorphic period occur in the area, striking in a north-westerly direction and dipping to the
northeast with over-thrusting from east to west.
.Final
Effective Date
14 of 237
Barkerville Gold Mines Ltd.: Cow Mountain NI43-101 Technical Report
Cariboo Gold Project
Post-metamorphic upright, open folds with axial planes approximately east-west deformed
the earlier period of folding such that the early fold axes now plunge to both the northwest
and the southeast along the length of the Barkerville Terrane.
During the late Cretaceous to early Tertiary a major period of northwest trending dextral
strike-slip faulting occurred with conjugate faults trending northwest and north, both with a
significant normal component of movement. The north trending fault structures appear to be
an important control for vein mineralization in the Wells area (Hall 1999) and that most of the
gold mineralization was deposited at that time although it is possible that there was already
earlier stage gold mineralization formed before and during the onset of metamorphism that
was remobilized during the post metamorphic period.
A protracted history of quartz veining that spans major deformation events is evident within
the rocks in the area, and studies have resulted in the recognition of five types of quartz
veining.
The majority of the historic underground production has been developed from quartz vein
and pyrite replacement types of mineralization. Both types of mineralization required narrow
vein mining methods in the historic operations to minimize dilution. Many vein structures and
pyrite zones within the deposits could not be mined at that time as they were too narrow.
However with modern bulk-mining methods, Snowden believes that the environs of the
historic operations are targets for further exploration.
The discovery by BGM in 2000 of the Bonanza Ledge style of mineralization (a pyrite
replacement style on the footwall of the Rainbow Unit) significantly widens the stratigraphic
package that has potential for gold mineralization and two types of pyrite replacement
deposits are recognised on both the footwall and hangingwall of the Rainbow Unit.
There are two other styles of mineralization recognized in recent years by BGM that are
neither quartz vein or pyrite replacement related and are basically altered host rock.

Quartzite hosted mineralization consisting of massive, dark to medium grey, massive
quartzite with 1% to 3% disseminated cubic pyrite.
 Faulted and fragmented zones in altered argillite, quartzite and phyllite containing
disseminated pyrite.

Current status exploration, development and operations
1.4.1
Exploration
The favourable geology and associated historical exploration and development over the
38 mile mine trend provide the Company with many exploration possibilities that will take
years to completely evaluate. Since June 2009, the Company’s exploration and development
activities have focused on the Cow Mountain and Barkerville Mountain areas with limited
grass roots prospecting activities and general application of self-potential geophysical
surveys outside the periphery of the Island Mountain – Cow Mountain – Barkerville Mountain
area. The Company is currently permitted for 600 drillholes on Island Mountain, and 840
drillholes on Barkerville Mountain as well as 12 drillholes on Mount Proserpine and 80
drillholes on Antler Mountain which is sufficient for near-term exploration to expand the
understanding of the exploration targets of these areas. As of the date of this report an
application to amend the permit for the drill program at Cow Mountain is in progress.

Barkerville Gold Mines Ltd.: Cow Mountain NI43-101 Technical Report
Cariboo Gold Project
Exploration over Cow Mountain includes geological mapping, soil sampling, some geophysics
and drilling. Overall Snowden is of the opinion that the exploration has been completed to a
sufficient standard to support the estimation of a Mineral Resource at Cow Mountain.
Snowden concluded that:

The information from drilling is good, with good core recovery and the sampling was
appropriate.

Prior to 2009, there was no QAQC and all work using data from pre-2009 drilling was
therefore deemed only suitable for the preparation of low confidence results, and results
to at best an Inferred Resource level of confidence.

QAQC of the 2009 and later sampling and assaying indicated reasonable quality of the
results, however, new work indicated that the original fire assay results did not account
for all of the gold in the samples, and metallic screen fire assays gave higher grade
results (in the order of 15% to 20% higher). These assays have been retested using the
metallic screen fire technique and the results of these retests form the basis for the
updated Technical Report.

Validation of the earlier results included some drilling of drillholes to twin existing
drillholes across the deposit. As a part of the twin drillholes campaign, intervals in the
original drill core that had previously not been sampled because of the lack of visible
mineralization were sampled and assayed. It was found that out of 84 samples, 28 had
an assay exceeding 0.1 ppm Au and 10 had an assay exceeding 0.012 oz/t (0.4 ppm)
Au. It appears that the selective sampling of apparent mineralization in the exploration
work has resulted in the lack of recognition of all of the mineralization. Otherwise, it was
concluded that the mineralization recognized in the new drillholes was consistent in
thickness and grade with the original drillholes (keeping in mind that the drillholes were
vertical and the mineralization is sub-vertical).
The Bonanza Ledge style of mineralization increases the overall exploration potential of the
mine-trend area as the areas underlain by extensions of the host geological unit have not
been explored to any extent.
1.4.2
Development and operations – Bonanza Ledge
As of the effective date of this Report the Company has completed test mining operations
under the Small Mines Permit for Bonanza Ledge deposit on Barkerville Mountain. A
Preliminary Feasibility Study was completed in 2009 (Fier et al. 2009) and recommended the
development of an estimated 200 tonne per day open pit mine (220 tons per day or
73,200 tons per year). The mine plan called for ore to be mined at an average grade of 0.26
oz/t (9 ppm/tonne) and hauled to the crushing and carbon-in-pulp (“CIP”) processing circuit
located at the QR Mill about 110 km or 68 miles away.
Initial analysis of the results from the test mining indicates further study is required before
economic extraction can be demonstrated for the Bonanza Ledge deposit. Production
statistics are listed in Table 1.1.

Metallurgical test work on samples from Cow Mountain drill core began in late 2010 and is
ongoing. An interim memorandum report prepared by F. Wright Consulting Inc. dated
November 1, 2014 provided the following interim conclusion, that Cow Mountain mineral
samples tested to date have shown a positive response to conventional metallurgical
procedures including gravity, froth flotation, and cyanidation techniques. Further work is
required, with preliminary data indicating an average gold recovery of 90% or greater can be
expected for Cow Mountain.

Bonanza Ledge
Mineral Resource and Mineral Reserve estimates were undertaken by Mintec Inc. (“Mintec”)
in 2009 on behalf of BGM’s precursor WGM, and are re-stated in metric terms in Table 1.2.
The classification categories for the Mineral Resource and the Mineral Reserve are
consistent with those defined in the CIM Standard definitions (CIM, 2010). There are no

Cow Mountain
Mineral Resource estimates were undertaken by Snowden on drillhole data provided by BGM
for the period ending Q3 2014. The Mineral Resources are reported above a cut-off grade of
0.5 g/t (ppm) (0.016 oz/ton) gold. This cut-off has been established based on the results of a
Whittle economic analysis.
The classification categories of the Mineral Resource are those defined in the CIM Standard
definitions (CIM, 2010). There are no Mineral Reserves for Cow Mountain in the current
study.

Notes:
(1) Mineral Resources which are not Mineral Reserves do not have demonstrated economic viability. The
estimate of Mineral Resources may be materially affected by environmental, permitting, legal, marketing,
or other relevant issues. The Mineral Resources were estimated using the Canadian Institute of Mining,
Metallurgy and Petroleum (CIM), CIM Standards on Mineral Resources and Reserves, Definitions and
Guidelines prepared by the CIM Standing Committee on Reserve Definitions and adopted by CIM
Council.
(2) The quantity and grade of reported Inferred Resources in this estimation are uncertain in nature and there
has been insufficient exploration to define these Inferred Resources as an Indicated or Measured Mineral
Resource and it is uncertain if further exploration will result in upgrading them to an Indicated or
Measured Mineral Resource category.
(3) Contained metal may differ due to rounding.
(4) The Mineral Resource estimate stated in Table 1.3 is defined using 25 ft by 25 ft by 25 ft blocks.
The Mineral Resource estimated is based upon an open pit scenario for the mining of gold
mineralization to a depth of 1,000 ft beneath the surface of Cow Mountain in an area
immediately surrounding the underground workings of the Cariboo Gold Quartz Mine. The
resource estimate involved the application of Multiple Indicator Kriging (“MIK”) for gold grade
estimation of a block model using Datamine® mining software.

Interpretation and conclusions
1.6.1
Bonanza Ledge
The conceptual mine plan operations, haulage and milling operations as described in the PreFeasibility Study (Fier et al. 2009) are no longer considered valid. Sections of the PreFeasibility Study prepared by EBA Consultants (Fier et al, 2009) are considered to be outdated due to:
.Final
Effective Date

Cariboo Gold Project
 Changes to capital and operating costs over time
 Changes to metal prices
 Purchase of the QR Mill such that toll milling is no longer applicable
 Purchase of property interests such that royalty payments are no longer applicable.
Consequently, Snowden completed a review to the economic analysis for Bonanza Ledge in
order to assess the relevance of the Mineral Reserve under the revised modifying factors.
Based on that analysis Snowden concludes there are no current Mineral Reserves at
Bonanza Ledge.
1.6.2
Cow Mountain
The Author, based upon his knowledge of the geology of the Cow Mountain area derived
from reports by the Company and various consultants to the Company and by on-site
examination of core and rock exposures in the area, has concluded that the open pit concept
for the Cow Mountain area, as first considered by Skerl (1948), initially evaluated by Wharf
Resources in the 1980s (Dykes 1997), and further evaluated by the Company based upon
data available to 1999/2001 (Giroux, 2002/2006), is valid.
The underlying premise in the exploration model is that there are widespread, small scale
veins and pyrite replacement zones that, if encountered during historic underground mining
would have been too small to be economically recovered during the historic underground
operations. Personal examination by the Author of outcrop and trenches in the Rainbow Unit
on Cow Mountain confirms this scenario and supports the underlying premise. Small quartz
veinlets are also routinely seen in drill core within the Rainbow Unit. In addition, observation
of prospecting trenches that were established during the summer of 2012 through to 2014 on
Cow Mountain, Island Mountain and Barkerville Mountain has further confirmed the
underlying premise.
The previous Mineral Resource (Geoex, Apex, Snowden 2012) was derived from the original
data with default values added to un-sampled intervals. Subsequently BGM embarked on a
re-assay program to obtain true values for these un-sampled intervals and to further obtain
metallic screen fire assays for the remainder of the assayed values used in the previous
estimate. The updated Mineral Resource was estimated using identical methodology as the
previous estimate to ensure consistency and allow comparison between the two estimates.
As before, the resultant resource estimates were prepared using Multiple Indicator Kriging
(“MIK”) in 25 ft by 25 ft by 25 ft blocks, and the prospect of economic extraction tested using
open pit optimization. As with the previous estimate, this demonstrated that the Project is
worthy of a more rigorous engineering study to evaluate the economic potential of the Mineral
Resource identified at Cow Mountain.
1.7
Potential targets for further exploration
The basis for this assessment of the exploration targets in the Island Mountain-Cow
Mountain-Barkerville Mountain region is as follows:
.Final
Effective Date
19 of 237
Barkerville Gold Mines Ltd.: Cow Mountain NI43-101 Technical Report
Cariboo Gold Project
 The assessment of the potential for future exploration targets is based only upon the
Island Mountain, Cow Mountain and Barkerville Mountain areas which are contiguous
mountains separated by valleys.
 The volume of the zone of potential mineralisation was defined as the strike length of the
“known” mineralization (from trenching and surface mineralization), multiplied by the
thickness of the known mineralization (from drilling and trenching), multiplied by the
known depth (from the old workings).
 A proportion of the available volume that can be considered as an upper limit for the
potential volume of mineralization of interest was defined as 20% of the total volume. A
proportion of the volume that can be considered as a lower limit was defined as 5% of
the volume of interest.
 A default density of 168.56 lbs/cu.ft (2.70 t/m3) was then applied to the volumes, each
multiplied by the proportion of the mineralization to determine the target tonnages.
 Grade ranges were defined according to the available information.
 The total number of ounces for each exploration target was given a lower value based on
the lower tonnage range value multiplied by the lower grade range value. For the upper
value, it was the authors’ opinion that the target was unlikely to have the higher grade
range value associated with the upper tonnage range value. Therefore the upper value
was based on the upper tonnage range value multiplied by the lower grade range value.
Note, the following assessments of potential quantity and grade are conceptual in
nature and there has been insufficient exploration to define a Mineral Resource and it
is uncertain if further exploration will result in any of the exploration targets being
delineated as a Mineral Resource.
1.7.1
Geological setting of Island Mountain-Cow Mountain-Barkerville
Mountain
 Continuity of Geological Setting and Mineralization – The geological setting and the
nature of known mineralization at Cow Mountain is the same as the geological setting
and the nature of known mineralization at Island Mountain and Barkerville Mountain.
 The Baker – Rainbow – BC and Lowhee units extend across all three mountains.
 All three mountains have surface exposures showing the widespread occurrence of
quartz vein stockworks.
 All three mountains have pyrite replacement mineralization.
 All three mountains have significant and laterally extensive gold in rock and soil
geochemical anomalies.
 All three mountains have numerous gold surface showings.
 Two of the mountains (Cow Mountain and Island Mountain) are underlain by
extensive underground workings with significant historic gold production and
extensive surface and underground drilling that demonstrates the presence of gold
mineralisation.
 Nature of Mineralization – The mineralization in all of the mines is similar, with
production from both quartz vein-type and semi-massive to massive pyrite-type settings.
.Final
Effective Date
20 of 237
Barkerville Gold Mines Ltd.: Cow Mountain NI43-101 Technical Report
Cariboo Gold Project
 The mine workings on Island Mountain were focussed on (but not exclusively on)
pyrite replacement zones which occur in the Baker Unit immediately above the
Rainbow Unit. The Island Mountain Mine workings extend from surface to a depth of
approximately 2,000 ft below surface and follow the northeast dipping RainbowBaker contact zone. 45% of historic production at Island Mountain came from quartz
vein and stockwork mineralization (most of which was in the Rainbow Unit) and 55%
from Pyrite replacement in the Baker Unit just above the Rainbow Unit.
 The Cariboo Gold Quartz Mine at Cow Mountain was collared in the lower part of the
Rainbow Unit and focussed on mining of discreet quartz veins and quartz vein
stockworks within the Rainbow Unit until the later years of production when a
number of pyrite replacement zones along the Rainbow-Baker contact were
discovered and mined.
 The Cariboo Gold Quartz Mine underground workings on Cow Mountain extend
10,000 ft from the 1500 Level portal (4000 ft elevation) to the BC Shaft beneath
Barkerville Mountain to the vicinity of the BC Vein and the Bonanza Ledge pyrite
replacement deposit.
 The Bonanza Ledge pyrite replacement deposit is located in the Lowhee Unit in the
footwall of the Rainbow Unit on the south-western flank of Barkerville Mountain.
 The total strike length of underground mine workings from Island Mountain to
Barkerville Mountain is approximately 17,000 ft.
 Surface rock and soil sampling along with surface and underground drilling show that
there is gold mineralization throughout the whole stratigraphic package from the
Baker-Rainbow contact area through the entire Rainbow Unit to the Lowhee Unit.
The Author’s interpretation based on the information available is that the
mineralization is likely to be laterally continuous from Barkerville Mountain through
Cow Mountain to Island Mountain.
 The Company has been acquiring land and carrying out exploration on the Property
since 1995. Prior to 1995, ownership of the mine trend was through a patch-work of
tenements and as a result, was inconsistently and mostly poorly explored. Of particular
importance is the lack of prior recognition in many parts of the high grade mineralization
in, and subsequent lack of exploration of, the pyrite replacement deposits (such as
Bonanza Ledge).
 Depth Potential – Historic underground mine workings and drilling along the Island
Mountain – Cow Mountain – Barkerville Mountain trend provide evidence that the gold
mineralization extends from surface to over 2,000 ft below surface and is open at depth.
 Soil Geochemistry – A number of soil geochemical grids were established over the
years covering much of the mine grid trend from Barkerville Mountain to northwest of
Island Mountain. For the area from Barkerville Mountain to Island Mountain there have
been more than 8,000 soil samples collected and analysed for gold over the years. The
soil samples have been collected over a 4.7 mile strike length from southeast to
northwest and form a gold geochemical anomaly. The anomaly extends for 4.7 miles
and ranges in width from 1,000 ft up to 3,300 ft, and is centred over the Rainbow Unit but
with significant anomalous soils over the lower Baker and upper Lowhee units in certain
areas.
 Exploration Drilling – Exploration drilling on Cow Mountain has been used to define a
Mineral Resource focussed within the Rainbow Unit. A total of 1,474 drillholes have been
completed in the Cow Mountain area.

1.7.2
Island Mountain exploration potential
The geological setting for Island Mountain is an extension of that of Cow Mountain. The
mineralized trend at Cow Mountain, based upon soils, drilling and trenching, extends to the
northwest into the Island Mountain sector.
Based upon the drillhole and soil geochemical data in conjunction with the geology the Island
Mountain trend as an exploration target is comparable to Cow Mountain with twice the strike
length at about 1.5 miles in length.
The past producing Island Mountain/Aurum and Mosquito mines (all in Island Mountain) have
underground workings extending to depths greater than 2,000 ft below the surface. In
addition to this, the mine workings from the Cariboo Gold Quartz Mine at Cow Mountain
extend to the northwest beneath Jack of Club Lake to Island Mountain. The historic workings
in conjunction with the drillhole data indicate that the Island Mountain exploration target
extends to a depth of at least 2,000 ft below surface.
Given a strike length of 1.5 miles (7,920 ft), width of 1,300 ft, depth of 2,000 ft, density of 168
lb/ft3, gives a tonnage range of 100 million tons to 350 million tons. The grade, according to
summary statistics of the available drill data at Island Mountain appears, however, to be
higher than that at Cow Mountain. Based on these grades, the Author has chosen to use a
grade range for the target of between 0.06 oz/t and 0.18 oz/t (2 to 6 ppm) and the target a
range of between 6 and 21 million ounces gold. The grades were based on the lower grade
from the contiguous Cow Mountain resource and the higher grade based on the average
grade of the historic drill data from the Rainbow Unit (Table 10.1). The higher tonnage was
used with the lower grade value to define the upper value of contained ounces as the authors
considered it less likely the higher tonnage would be associated with the higher grade values.
These results in combination with historic underground mining and the existing gold in soil
geochemical anomaly make the Island Mountain area a high priority target for further
evaluation.
Note, the following assessments of potential quantity and grade are conceptual in
nature and there has been insufficient exploration to define a Mineral Resource and it
is uncertain if further exploration will result in any of the exploration targets being
delineated as a Mineral Resource.
1.7.3
Barkerville Mountain target potential
The geological setting beneath Barkerville Mountain is an extension of that of Cow Mountain.
The mineralized trend at Cow Mountain, based upon soils, drilling and trenching, extends to
the southeast across the narrow Lowhee Creek valley into the Barkerville Mountain sector.
The Barkerville Mountain area, based upon the extent of the soil geochemical anomaly and
gold mineralization identified in trench sampling and limited drilling appears to have a
potential strike of 1.1 miles.

Given a strike length of 1.1 miles (5,800 ft), width of 1,300 ft, depth of 1,000 ft, the author
suggests a target with a tonnage range of between 50 million tons and 100 million tons. The
author has chosen to use the grade range as per the Island Mountain target and consistent
with the neighbouring Cow Mountain resource, giving the project a grade range for the target
of between 0.06 oz/t and 0.15 oz/t (2 to 5 ppm) and the target a range of between 3 and 6
million ounces gold. The grades were based on the lower grade from the contiguous Cow
Mountain resource and the higher grade based on the average grade of the historic drill data
(above 0.012 oz/t) from the Rainbow Unit. The higher tonnage was used with the lower
grade value to define the upper value of contained ounces as the authors considered it less
likely the higher tonnage would be associated with the higher grade values.
Note, the following assessments of potential quantity and grade are conceptual in

is uncertain if further exploration will result in any of the exploration targets being
delineated as a Mineral Resource.
1.7.4
Cow Mountain target potential
The mineralized trend at Cow Mountain, based upon soils, drilling and trenching, extends to
the southeast across the narrow Lowhee Creek valley into the Barkerville Mountain sector.
The current mineral resource model limits are defined in Table 14.4 and represent the extent
of the inferred and indicated categories. Beyond this limit the current drilling is too widely
spaced to meet the inferred category, however based on:
 the current understanding of the potential of Cow Mountain
 the grades intersected in the 2014 drilling
 the results of the BGM surface channel sampling and geologic mapping
Given the approximate strike length of 1640 ft width of 1312 ft and dip length of 984 ft
Snowden suggests a target of between 20 and 25 million tons at a grade range of 0.06 oz/t
and 0.15 oz/t (2 to 5 ppm) and a target range of between one million and three million
ounces. The grades were based on the lower grade from the contiguous Cow Mountain
resource and the higher grade based on the average grade of the historic drill data (above
0.012 oz/t) from the Rainbow Unit.
Note, the following assessments of potential quantity and grade are conceptual in
nature and there has been insufficient exploration to define a Mineral Resource and it
is uncertain if further exploration will result in any of the exploration targets being
delineated as a Mineral Resource.
1.7.5
Total exploration potential of Island Mountain Cow Mountain and
Barkerville Mountain
The total exploration target potential of the 4.5 mile long mineralized trend including the
Barkerville Mountain target and the Island Mountain target is 170 to 475 million tons (rounded
to the nearest fifty) between 0.06 oz/t and 0.15 oz/t (2 to 5 ppm) Au and the target a range of
between 10 and 30 million ounces gold.
In addition, there are a number of other targets including mineralization associated with the
Bonanza Ledge stratigraphic setting and the Rainbow-Baker replacement style for which
there is strong evidence for but not enough work to properly define.

1.8
Recommendations
1.8.1
Bonanza Ledge
Snowden recommends that the Bonanza Ledge project be re-assessed through incorporation
into the much larger Island Mountain / Cow Mountain / Barkerville Mountain resource
evaluation. Snowden recommends an open pit life of mine plan be developed including a
comprehensive economic analysis be completed at the Bonanza Ledge deposit. Snowden
recommends BGM continue to build an exploration and development plan based on primary
mineralization controls from first principals.
1.8.2
Cow Mountain and exploration
In order to expand upon the Mineral Resource and potential of the Property, Snowden
recommends the following:
 Drill test the mineralization across the entire Rainbow formation from hangingwall to
footwall to expand the resource and also test the mineralization to the southeast of the
current resource limit to expand the Cow Mountain resource along strike.
 Assess the need for additional drilling to improve the local confidence.
 Create and maintain a robust database including management of QAQC.
 Establish and maintain an industry standard secure database for all drill log information.
 Construct a comprehensive 3D computer geologic model to develop regional targets for
exploration drilling.
 Island Mountain drill data validation and evaluation.
 Evaluate the potential of the exploration targets at Island Mountain and Barkerville
Mountain through further trenching and drilling.
 As previously recommended where appropriate, complete all current assay tests using
metallic screen fire assays (a technique that employs a larger sample size for analysis of
drillcore).
 Snowden recommends continual monitoring of QAQC results.
 Snowden recommends a library of standard operating procedures for all drill core
processing to be established by the Company.
The following phased programme is recommended (Table1.4). Drilling related costs are
based upon actual costs of the 2014 drill programme. The all-inclusive drilling costs include,
footage costs, wages and benefits, road and pad construction, driller bonus, mob-demob,
and miscellaneous. Assay costs have been increased to reflect the higher cost of screened
metallic analysis. Other costs are order of magnitude estimates.

Introduction
Snowden Mining Industry Consultants (“Snowden”) was requested by Barkerville Gold Mines
Ltd (“BGM”) listed on the Toronto Venture Exchange (BGM.TSX-V) to prepare this updated
independent National Instrument (“NI 43-101”) Technical Report (“the Report”) of the Cariboo
Gold Property (“the Property”).
The Company, previously known as International Wayside Gold Mines Ltd. (“WGM”), has
been active in the Cariboo area of British Columbia since 1994 and has gradually put
together a large package of mining tenures that covers all of the historic underground gold
mining properties in the area as well as the majority of claims that cover the bulk of the 38
mile long mine-trend. It extends from 16 miles (25.7 km) to the north of Wells, to Cariboo
River 22 miles (35.4 km) south of Wells.
The last NI 43-101 Technical Report for the Cariboo Gold Property area was dated
December 31, 2012 (Geoex, Apex, Snowden 2012). Since the last filed report, BGM has
purchased three mineral claim groups within the project area. The total land package is
currently a size of 454.5 square miles. Snowden is unaware of any other acquisitions or
additions to the Company property portfolio.
This Report has been prepared by Mr. Walter Dzick P.Geo., BSc., MBA, MAusIMM,
APEGBC, AIPG of Snowden.
2.1
Terms of reference
The purpose of the Report is to provide the Company with an independent opinion with
regard to the Mineral Resources in the Cow Mountain area, the potential of the contiguous
6.2 mile (10 km) long trend from Island Mountain-Cow Mountain-Barkerville Mountain area
and the general, overall potential of the Property. The status of Bonanza Ledge development
is briefly discussed.
The Report has been prepared to support the Company’s disclosure of Mineral Resource
estimates and conform to the format and content required under the National Instrument 43101 (“NI 43-101”) regulations of the Canadian Securities Administrators, including Form 43101F1, and other related guidelines.
The Report was prepared by Mr. Walter Dzick, P.Geo. BSc, MBA, MAusIMM, APEGBC,

Property description and location
4.1
Property area and location
The Company’s mineral tenures are found on NTS sheets 093H/03, 04 and 05 as well as
093A/13 and 14 and can be queried using the BC Mineral Titles website
(www.mtonline.gov.bc.ca). An outline of the current land holdings is shown on Figure 4.1. A
complete listing of the land holdings within the Property area is presented in Appendix A. The
Company has assured Snowden that there has been no material change to the land holdings
and title opinion as of the date of this Report.
The Property is comprised of staked mineral tenures and Crown-granted mineral claims
covering an area of 454.50 square miles along a strike length of 38 miles and approximate
width of 12 miles. Since the last filed report, BGM has purchased three mineral claim groups
within the project area. The total land package is currently at a size of 454.5 square miles or
117,714.97 hectares. Snowden is unaware of any other acquisitions or additions to the
Company property portfolio.
Within the Property there are still several legacy claims belonging to other persons or
companies which have first right to the mineral contained within those boundaries. Should
those legacy claims lapse, then the mineral rights will immediately belong to BGM as per the
Mineral Tenure Act. None of these legacy claims encumber the immediate project area of
Island, Cow or Barkerville mountains, the subject of this Report. There are also a number of
active Crown-granted mineral claims and F-Grants which encumber the Property. These
claims have first rights to certain minerals along with other possible rights as outlined in the
original titles which were granted under the Land Act up to 140 years ago. While some
groups of these Crown-granted mineral claims are found on or immediately adjacent to
Island, Cow and Barkerville mountains, none of these Crown-granted mineral claims
encumber or have any impact on the Mineral Resources that are subject of this Report.

Property underlying agreements and obligations
The Company has assured Snowden that all of the underlying agreements relating to the
mineral tenures and Crown-granted claims are valid and that all their mineral tenures are up
to date in terms of annual expenditure requirements.
.Final
Effective Date
31 of 237
Barkerville Gold Mines Ltd.: Cow Mountain NI43-101 Technical Report
Cariboo Gold Project
The Company has assured Snowden that there are no royalties or other payments required
to be paid on the Island Mountain-Cow Mountain-Barkerville Mountain areas of the Property
that underlie the Mineral Resources and exploration targets that are the subject of this Report
other than the Myrtle Property which was acquired in the summer of 2011 and has a 3% Net
Smelter Return (“NSR”). The Myrtle Property is located on the summit and southeast flank of
Barkerville Mountain above the Barkerville Historic Town. There are, however, several claim
groups which are subject to net smelter royalties but in areas beyond the Island MountainCow Mountain-Barkerville mountain areas of the Property (Appendix A).
Annual expenditures to retain all of the mineral tenements in good standing are
approximately $2,350,000. The Company has sufficient expenditure accrued to maintain the
mineral tenements in good standing until 2020. In July 2012, the Mineral Tenure Act was
revised and, as a result, the current cost to maintain the Property beyond 2020 is $20/hectare
per year ($8/acre). As the claims are contiguous, except for one small claim at present, the
allowable assessment expenditure may be anywhere on the Property and spread to cover the
annual requirements of the whole Property. In addition to the mineral tenure expenditures
required to maintain the mineral property rights granted under the Mineral Tenure Act, there
are also Mineral taxes and BC Assessment land taxes associated with each of the Crowngranted mineral claims owned by the Company. These taxes are payable each year in
association with the under surface and surface rights of certain lots as listed in Appendix A.
4.3
Property, other obligations
In order to continue exploration and development activities on the Property, the Company
must obtain and maintain their permits and comply with certain Acts including but not limited
to the Mineral Tenure Act and the Mines Act. In regard to permitting exploration and
development, the Company has to consider other land issues where applicable:
archaeological assessment, terrain stability assessment, fish habitat, water quality, wildlife
habitat, heritage properties, staking reserves, timber rights, road use, surface rights and other
land users, as well as other items as directed by the Mines Inspector. Snowden is not aware
of any encumbrances which would significantly affect or impede exploration and development
in the Island Mountain-Cow Mountain-Barkerville Mountain project area.
Environmental reclamation securities or bonds are posted for each of the areas where mining
or exploration has been approved. The Company also maintains regular water/environmental
and wildlife monitoring activities as part of their permitting requirements within the Island
Mountain-Cow Mountain-Barkerville Mountain project area.

Accessibility, climate, local resources, infrastructure
and physiography
5.1
Accessibility
The Property is approximately 50 road-miles east of the City of Quesnel and is accessible via
Highway 26 that branches off Highway 97 adjacent to the Quesnel Airport. There are daily
scheduled flights from Vancouver to Quesnel and flying time is 1.5 hours.
The Company’s project offices and related facilities are located in the town of Wells which is
centrally located within the Property area. Gravel roads established during historic placer
and lode gold mining activities provide access throughout the Property area.
There is a 2,700 ft paved airstrip 3 miles east of Wells near the site of Barkerville Historic
Town. The airstrip is owned and maintained by the British Columbia Government. The
airstrip is unattended and has no services for fuel but is suitable for medevac and scheduled
or non-scheduled flights with appropriate aircraft.
5.2
Climate and physiography
The area is known as the “Interior Wet Belt” in British Columbia and in the Ecoregions of
Canada, is known as the Columbia Mountains and Highlands ecoregion. The ecoregion is a
complex of elevationally stratified montane to alpine ecosystems. The mean annual average
temperature in the region is 5oC with a summer mean of 14oC and a winter mean of -5oC.
Average annual precipitation is up to 48 inches and in the Wells area; cumulated snow
depths of up to 6 ft are common.
Topography in the Property area is moderately mountainous with relief in the immediate
vicinity of Wells of approximately 2,100 ft; (3,900 ft above sea level in the valley area near
Wells to 6,000 ft elevation on Mount Proserpine, 6.8 miles south of Wells). Roundtop
Mountain, 15.5 miles south of Wells, is the highest point on the Property at 6,755 ft above
sea level.
Summits are generally rounded, having been intermittently glaciated by mountain and
continental ice sheets over the past 1.8 million years. Glacial till is the most widespread
surficial deposit in the area. In spite of the relief in the area, bedrock exposure is poor except
along creeks, ridgelines and logging roads.
The Property is densely forested with second-growth spruce, pine and fir, along with alders
and other deciduous varieties.
5.3
Local resources and infrastructure
Quesnel, approximately 50 miles west of the Property, is the major supply and service centre
for resource industries in the area and there is access to a workforce in the region. The
closest regional hospital is in Quesnel.
There is sufficient power and water available in the Property area to support a mining
operation. Canadian National Railway from Quesnel provides rail access to the Port of
Vancouver.

The Company has sufficient surface rights in the Property area for mineral exploration and
development, including the use of timber and water, as generally conveyed in some of the
rights given with the Company’s Crown-granted mineral claims or with certain permitted
rights, including tailings and waste disposal areas. The resources required, which are
currently provided locally, include single-phase 7.2 kV power, potable water from the District
of Wells public water works well which provides about 985,000 L of water per day to the town,
local sewage treatment and waste disposal sites, high-speed internet service and
telecommunication services as well as Company maintained communication towers for use
by Company personnel and site contractors. The Company also holds two water licences at
present: one for Willow River and one for a well installed at the geological compound and
field offices at Lowhee Creek. The climate would not impede full time mining operations in
the area.

History
6.1
Prior Ownership
Predecessor companies of the Company initiated land acquisition in the Barkerville area in
1994. In 2009, WGM completed the consolidation of the land package by acquiring the
contiguous projects of Island Mountain Gold Mines Ltd., “IGM”) and Golden Cariboo
Resources Ltd. (“GCC”); all related parties and listed on the TSX Venture Exchange. WGM
first optioned a 50% interest in the Island Mountain/Aurum Gold Mine and Mosquito Creek
Gold Mine properties to IGM on May 12, 1999. That option was then renegotiated in
October, 2004. During January 2006 WGM agreed to buy back the 50% interest in the
optioned lands and purchase all of IGM’s land holdings northwest of the town of Wells, British
Columbia. This was approved by the TSX Venture Exchange on May 2, 2006. To finalize the
consolidation of the major land holdings in the Barkerville Gold Belt, WGM acquired all of the
lands controlled by GCC which lay along strike in the known mineralized trend for some
15 miles from Barkerville Historic Town southeast to the Cariboo Hudson Mine. The
acquisition of GCC’s tenure holdings was approved by the TSX Venture Exchange on
April 9, 2009, resulting in WGM’s land tenure extending 38 miles and encompassing the
majority of the known strike length of the Barkerville Gold Belt.
On January 20, 2010, WGM changed its name to Barkerville Gold Mines Ltd (“BGM” or “the
Company”).
6.2
Summary of historic exploration and development work
Parts of the Property have a very long history of exploration and development dating back to
the late 1800s. It is beyond the scope and technical requirements of the Report to review all
of the historical information, however, an overview of significant hardrock gold showings and
past producing gold mines is included (Section 6.3). Yin (2010, 760p.) provides a complete
set of references for all available records relating to historic work on the Property, 0 contains
a list of all assessment reports for the Property for the period 1949 to 2010.
A review of the data in 0 clearly indicates that the majority of the historical work is all very
early stage exploration work.
The only historic work pertinent to the resource estimate for the Cow Mountain area is the
1980-81 drilling by Wharf Resources and subsequently drilling and related work completed by
the Company.
The only other historic work pertinent to the potential of the Property is the current report, the
regional geological setting and the regional distribution of hardrock and placer gold
operations and showings which has been reviewed in this Report.

Historical production and landholdings
6.3.1
Placer gold production
The first placer gold discovery in the Cariboo was made in 1859 at Horsefly River
approximately 60 miles south-southeast of Barkerville Historic Town followed by more strikes
at Keithley Creek (25 miles south-southeast of Barkerville Historic Town) in 1860. As news
spread, the gold rush fully commenced in 1861 and in 1862 the Williams Creek placer was
discovered near what is now the town of Barkerville Historic Town. It has been estimated that
in excess of 2 million ounces (Moz) of placer gold was produced to the end of the 1800’s.
The total amount is uncertain as government recordings of gold recovery did not start until
the 1880s.
A review of placer production and its location relation to bedrock geology is provided in
Section 6.3.
6.3.2
Lode gold production
In the 1860s when all of the placer claims in the area, with potential or otherwise, had been
staked, the search for the lode gold source of the placer mineralization began. The Black
Jack, Home Stake, Cornish, and Wintrip were early significant lode gold discoveries in the
1860s. Exploration for lode gold continued into the 1900s and ultimately resulted in four
significant producers in the Barkerville area, the Aurum, Island Mountain and Mosquito Creek
mines (all on Island Mountain and all mining similar mineralization in the same geological
setting along the Rainbow Unit Baker Unit contact), and the Cariboo Gold Quartz Mine,
immediately to the southwest on Cow Mountain which also has similar mineralization in the
same geological setting in the Rainbow Unit. Mining at the Cariboo Gold Quartz Mine
(“CGQM”) was primarily in the Rainbow unit.
The Aurum/Island Mountain/Mosquito Creek mines were mined to a depth of 2,100 ft (2550 ft.
elev.) below surface and are open at depth and along strike to the northwest. The last
production from the Aurum/Island Mountain Mine was in 1967. The only production from
Mosquito Creek was in the period 1980 to 1983, and 1984 to 1987.
Prospecting supervised by Fred Wells resulted in the discovery of gold-bearing quartz veins
on Cow Mountain in the late 1920s which led to development of the Cariboo Gold Quartz
Mine. Production was from 5 zones known as the Tailings, No.1, Rainbow, Sanders and
Pinkerton along a strike length of 5,000 ft to a maximum depth of 1,500 ft below surface.
Production ceased in 1959. The Cariboo Gold Quartz Mine was mined to a depth of 1,500 ft
(3343 ft elev.) below surface and is open at depth and along strike to the southeast beneath
Barkerville Mountain. Here underground workings explored the BC Vein on the 1500 Level
(4000 ft. Elev.) along a strike length of 10,000 ft to the vicinity of BC Shaft and the Bonanza
Ledge deposit. The Company is currently developing the Bonanza Ledge deposit as an open
pit operation, on the southwest flank of Barkerville Mountain at the headwaters of Lowhee
Creek and Stouts Gulch.
Historic production from these mines is presented in Table 6.1 (from Hall 1991, p.9).
