1.0 SUMMARY
Pincock, Allen & Holt Ltd. was retained by Silver Standard Resources Inc. to prepare an
independent Technical Report that meets the requirements of Canadian National Investment 43-
101 on the Sulphurets-Bruceside Property in British Columbia (BC). The Sulphurets-Bruceside
Property is located in northern BC, 900 kilometers from Vancouver. Access to the property is
by helicopter from the town of Stewart, 62 kilometers south-southeast of the property. Silver
Standard Resources owns a 60 percent interest in the Sulphurets-Bruceside Property as a result
of the acquisition of Newhawk Gold Mines Ltd in September 1999. Black Hawk Mining Inc.
owns the other 40 percent. The Sulphurets-Bruceside property consists of the Bruceside claim
group, with 28 recorded claims containing 146 claim units valid until January 31, 2010. There
are no holding-cost obligations to Silver Standard.
Esso, Granduc and Newhawk, who acquired their initial interest in 1984, actively explored the
property from the 1970s to 1994. Since then Newhawk carried out a series of exploration
programs that included mapping, trenching, sampling, underground development on the West
Zone, and both surface and underground diamond drilling. A feasibility study was completed in
1990.
The property is underlain by the Jurassic age Hazelton Group that consists of argillites, cherts,
andesitic pyroclastic tuffs and breccias intruded by Mid-Jurassic stocks of diorite to granite
composition. Mineralization is associated with a zone of intense quartz-sericite-pyrite alteration
that is 100 to 450 meters wide and 4.5 kilometers long. The West zone, which contains the bulk
of the known mineral resource, is a southwest-trending vein system consisting of ten individual
veins.
Based on the previous work by other independent consultants, the Sulphurets-Bruceside
Property contains a measured and indicated mineral resource of 1,135,800 tons averaging 0.371
ounces gold per ton and 15.1 ounces silver per ton, with an additional inferred mineral resource
Pincock, Allen & Holt 2 9814.00d April 16, 2001
of 151,300 tons at a grade of 0.542 ounces gold per ton and 5.0 ounces silver per ton. Based on
a Ag:Au equivalency ratio of 55:1, this amounts to a measured + indicated resource of 40.3
million ounces of silver-equivalent and an inferred resource of 5.2 million ounces of silver-
equivalent. The total resource is summarized in Table 1-1.

It is PAH’s opinion that the estimation of the mineral resources, as stated above, has been
prepared according to accepted industry standards using accepted practices and that the work
completed has been both thorough and as accurate as possible given the available database. It is
PAH’s opinion that the classification of measured, indicated and inferred mineral resources as
estimated herein, meets the definitions of measured, indicated and inferred mineral resources as
stated by NI 43-101 and defined by the CIM Standards on Mineral Resources and Reserves
Definitions and Guidelines adopted by the CIM council on August 20, 2000.
The Sulphurets-Bruceside property is considered to have the potential for additional resources
both at depth, in the veins explored to date, and in other targets that have yet to be fully
delineated. Because of the isolated location of the property, higher gold and silver prices are
required before further exploration programs can be recommended. Silver Standard has not
proposed a work program and budget for the current year.

it materially change the overall conclusions of this Report.
PAH has, in part, relied upon portions of the reports of other persons who are believed to be
“Qualified Persons” as defined in NI 43-101. (see References).
Pincock, Allen & Holt 6 9814.00d April 16, 2001
4.0 INTRODUCTION
4.1 Location and Access
The Sulphurets-Bruceside property is located in the Coast Range Mountains of northwestern
British Columbia approximately 900 kilometers north of Vancouver and 240 kilometers north of
the town of Prince Rupert (Figure 4-1). Latitude and longitude are 56 degrees 29 minutes north
and 129 degrees 13 minutes west, respectively, and corresponding to NTS sheets 104B/8-9.
Access from the town of Stewart (62 kilometers south-southeast of the property) is currently by
helicopter. During the underground exploration period in the late 1980s, freight, supplies and
personnel were transported from Stewart overland via paved Highway 37, then by gravel road to
Bowser Lake, then by barge along Bowser Lake (25 kilometers) then by road along Bowser
River and finally by tracked vehicle up the Knipple Glacier (15 kilometers) and a further 3.0
kilometers of gravel roads to the camp site.
4.2 Climate
The climate in the area of the Sulphurets-Bruceside property is harsh. Winters are long and cold
with heavy snowfall and high winds, while summers are cool and wet. Vegetation is sparse
with only some scrub spruce and fir at lower elevations along creeks, and juniper and alpine
grasses at higher elevations. The property is rugged terrain with steep glacial carved valleys
and rocky ridges.
4.3 Local Resources and Infrastructure
The towns of Terrace and Smithers are located in the same general region as the Sulphurets-
Bruceside property. Both are directly accessible by daily air service from Vancouver. Stewart
Pincock, Allen & Holt 8 9814.00d April 16, 2001
has good road access but does not have scheduled air service. There was a permanent camp on
the property at Brucejack Lake but this has been dismantled and the site reclaimed.
4.4 Physiography
The property occupies a large ice covered ridge at elevations ranging between 550 and 1,830
meters above sea level. The terrain is rocky and rugged with permanent ice fields filling the
upper reaches of many of the valleys. The former Brucejack Lake exploration camp was at
1,375 meters elevation on a high plateau above the timberline and the lake is ice-bound most of
the year. An underground mine portal formerly used for underground access and sampling is
located near the campsite at 1,382 meters elevation.
4.5 Project Ownership
Silver Standard owns a 60 percent interest in the Sulphurets-Bruceside property. The property
occurs in the Sulphurets Project area and consists of the Bruceside claim group. (Figure 4-2).
Silver Standard acquired these claims as a result of the acquisition of all the outstanding shares
of Newhawk Gold Mines Ltd., in September 1999. Black Hawk Mining Inc. who acquired their
interest by a merger with Granduc Mines Ltd in July 1996 holds the remaining 40 percent
interest in the Sulphurets-Bruceside property. Silver Standard also owns a 100 percent interest
in the adjoining Sulphurets-Snowfield property as a result of the acquisition of Newhawk Gold
Mines Ltd.
4.6 Land Tenure
As of January 25, 2001, the Sulphurets-Bruceside property consists of 28 recorded claims
containing 146 claim units in the Bruceside claim group (Table 4-1) (Figure 4-2). PAH has not
independently verified title and ownership, and the list of claims and the information herein was
derived from a search of the B.C. Ministry of Energy and Mines database and confirms
Pincock, Allen & Holt 10 9814.00d April 16, 2001
information provided by Silver Standard. All claims lie within the Skeena Mining Division and
are recorded under Newhawk Gold Mines Ltd. (now a wholly owned subsidiary of Silver
Standard). A legal survey has not been undertaken.

4.7 Permitting
PAH has relied on statements by Silver Standard as to the status of permits and any outstanding
environmental liability. There is no current or future exploration planned for the Sulphurets-
Bruceside property, and no permits are currently required. Silver Standard has indicated that
the camp and dumps have been reclaimed with the exception of a small area of fuel
contamination that is currently being treated and that there are no current environmental
liabilities. This is the last year of required water testing.
It is believed that little remaining environmental liability exists at the property, but PAH cannot
make a definitive determination at this time.
Pincock, Allen & Holt 12 9814.00d April 16, 2001
5.0 HISTORY OF THE PROJECT
The area encompassing the Sulphurets-Bruceside property has been intermittently explored for
precious and base metals for more than 100 years. Earlier work is generally not well
documented, but activities since the 1950s are reasonably well known. The following is a
chronological description of mineral exploration in the Sulphurets Creek - Brucejack Lake area.
1930s Churn drill testing for placer gold on Sulphurets Creek. 1935 Prospectors discover copper mineralization about 6 kilometers northwest
of Brucejack Lake. 1959 Gold and silver mineralization discovered in upper Sulphurets Creek
area. 1960 Granduc Mines Limited and Alaskan prospectors staked the main
Sulphurets claim group. 1961-1968 Prospecting led to the discovery of several gold-silver and copper
occurrences, six copper-molybdenum zones tested with 40 diamond drill holes.
1970s Granduc conducted geological mapping, sampling, geophysics,
prospecting and limited drilling on known base and precious metal targets north and northwest of Brucejack Lake.
1980-1984 Esso Minerals optioned the property and carried out exploration for
porphyry targets. Esso drilled a total of 8,230 meters. 1985 Newhawk (60%)-Granduc (40%) joint venture formed. Approximately
3,600 meters of drilling was carried out on the West, Shore, and Gossan Zones.
1986-1990 Joint venture initiated underground exploration and development of the
West Zone. During the period, a total of 35,000 meters of surface drilling, 14,800 meters of underground drilling, and 5,230 meters of underground development on the West Zone were carried out. In 1990, resources were calculated by WGM. Corona completed a feasibility study.
Pincock, Allen & Holt 13 9814.00d April 16, 2001
1991-1994 Trenching, mapping, airborne surveys, and surface drilling were carried out by Joint Venture on a property-wide scale evaluating surface targets, including the Shore Zone, Gossan Hill, Galena Hill, Maddux and SG. A total of 12,974 meters were drilled in 57 holes on the Sulphurets-Bruceside Property.
1995-2000 No exploration or development work was carried out on the properties.
The camp and waste-rock dumps were reclaimed in 1999.
Pincock, Allen & Holt 14 9814.00d April 16, 2001
6.0 GEOLOGICAL SETTING
6.1 Regional Geologic Setting
The Sulphurets-Bruceside property, which lies within the Stikine Terrain, is underlain by
Hazelton Group volcanic, volcaniclastic and sedimentary rocks of upper Triassic to lower and
middle Jurassic age (Figure 6-1). The Hazelton rocks are intruded by Mesozoic felsic to
intermediate plutons and a few Tertiary mafic dikes and sills. Mapping by Britton and Alldrick
(1991) and by Kirkham (1994) subdivides the Hazelton Group into several formations:
sandstone and conglomerates, of the lower Unuk Formation; volcanics and siltstones of the
upper Unuk Formation; interbedded conglomerates, sandstones, and intermediate to mafic
volcanics of the Betty Creek Formation; felsic pyroclastic and tuffaceous rocks, of the Mount
Dillworth Formation; and siltstones and sandstones, of the Salmon River Formation. The
youngest rocks in the region are sedimentary rocks of the Bowser Lake Group. Hazelton Group
rocks are gently folded, with strong north-south steeply dipping normal and reverse faults.
Intrusive rocks include felsic plutons that are probably coeval with the Jurassic volcanics,
Cretaceous Coast Plutonic Complex Batholiths and stocks and minor Tertiary diabase dikes and
sills.
6.2 Property Geology
Two sedimentary and volcanic assemblages underlie the Sulphurets-Bruceside Project claims;
Upper Triassic Stuhini Group rocks on the west and Jurassic Hazelton Group rocks in the
central and eastern parts of the claim area (Figure 6-2).
The oldest rocks on the property are the Lower Sediments that are reported to have a thickness
of 1,500 meters and consist of argillites, siltstones and cherts. They are overlain by pyroclastic
rocks that range from tuff to breccias, and may contain blocks up to 1 meter in size. Most of
Pincock, Allen & Holt 17 9814.00d April 16, 2001
the volcanics are andesitic in composition and have been subjected to varying degrees of
alteration. These altered tuffs and breccias are the host of the mineralization. Overlying the
volcanics are the upper sediments that consist of a sequence of black shales and argillites similar
to the lower sediments.
The volcanic-sedimentary sequence is cut by two elongated northerly-trending zones of
intrusive stocks of Middle Jurassic age ranging in composition from diorite to granite.
Post-mineral deformation and faulting are common with the north-striking Brucejack Fault and
the west-trending Bruce Fault being the most prominent.
Pincock, Allen & Holt 18 9814.00d April 16, 2001
7.0 DEPOSIT TYPE
The West Zone is a structurally controlled complex vein system containing gold and silver
mineralization. The vein system may be related to the Brucejack fault lying to the immediate
west. It is considered to fit the high-grade, low-sulphidation model. Other examples in B.C.
include Blackdome and Silbak Premier.
Pincock, Allen & Holt 19 9814.00d April 16, 2001
8.0 MINERALIZATION
A north-trending zone of intense quartz-sericite-pyrite alteration 100 to 450 meters wide and 4.5
kilometers long cuts through the central part of the claim group. The alteration is pervasive and
hosts over 40 known zones of structurally controlled quartz-carbonate gold-silver bearing veins,
stockworks and breccias. The most important ore-bearing structures occur within a complex
vein system and can range from a few centimeters up to 50 meters wide and can contain up to
60 percent quartz. Individual mineralized zones range in length from several meters to several
hundred meters.
The majority of the veins trend northwest-southeast and dip steeply northeast. Less common
are northeast trending and east west striking veins that can have dips of 60 degrees north to
vertical.
8.1 West Zone
The most important mineralized zone on the property is the West Zone, where the underground
development was carried out. The West Zone is a structurally controlled southwest-trending
vein system that is possibly related to splay faulting from the north-trending Brucejack Fault.
Metallic mineralization within the West Zone alteration zone consists primarily of disseminated
pyrite and minor arsenopyrite. The vein mineralogy consists of up to 10 percent disseminated
pyrite with variable amounts and combinations of tetrahedrite, tennantite, arsenopyrite,
chalcopyrite, galena, pyrargyrite, sphalerite, polybasite, electrum and native gold.
The zone consists of ten individual veins that vary in thickness and length, that generally plunge
steeply southeast and dip steeply northeast, and are contained within an envelope of alteration
(Figures 8-1, 8-2). The most important veins in terms of contained ounces are the R-4 and R-8.
Pincock, Allen & Holt 22 9814.00d April 16, 2001
The R-4 vein extends 280 meters vertically and consists of two shoots each about 40 meters in
strike length increasing to 130 meters at depth with an average grade of 0.441 opt Au and 27.1
opt Ag. The R-8 vein has a strike length of 80 meters and an average width of 2 to 5 meters
with a vertical extent in excess of 190 meters. It has a 58-degree dip and averages 0.623 ounces
gold per ton and 12.4 ounces silver per ton with a high-grade core averaging 1.259 ounces gold
per ton and 20.5 ounces silver per ton.
8.2 Satellite Zones
Shore Zone
The Shore Zone is a 500- by 50-meter zone of mineralized stockworks, breccias and veins
enclosed in a 150-meter wide zone of phyllic-sericitic alteration. Individual veins are stacked
en echelon with lenses up to 100 meters long and 1.5 meters wide. Grades are variable, the best
intersection to date is 2.24 ounces per ton gold, 4.3 ounces per ton silver over a true width of 10
meters. Drilling has amounted to 10,945 meters in 63 holes. The zone is open at depth.
Gossan Hill
Eleven zones of individual east-west striking quartz-carbonate-sericite veins, and stockworks
containing up to 10 percent sulphides have been identified to date. Individual veins can be up to
245 meters long with widths of up to 20 meters. The Tommyknocker and PM-4A are the most
significant zones. The mineralization is erratic within the structures and drilling in 1994
indicates the zone persists to at least 200 meters below surface but with no increase in grade.
Total drilling to date is 7,380 meters in 40 holes.
Galena Hill
The Galena Hill Zone is underlain by altered volcanics containing a 200- by 400-meter area of
quartz-sericite-pyrite alteration that contains eight northeast-southwest steeply dipping sulphide-
Pincock, Allen & Holt 23 9814.00d April 16, 2001
bearing quartz veins up to 285 meters long and up to 8 meters wide. Since 1981, 28 holes
totaling 3,000 meters have tested the veins over a 250-meter strike length. The best intersection
is 1.565 opt Au over 3.0 meters. With the exception of one vein, G-8, which has been tested
with 13 holes and is 250 meters long and up to 3 meters wide, the majority of the veins,
although continuous along strike and down dip, are too narrow and low grade to be of interest.

The SG vein, one of six veins contained within quartz-sericite-pyrite alteration zones has been
evaluated by 874 meters of drilling in seven holes and 123 meters of surface trenching in 27
trenches. The zone of quartz veining, stockworks and breccia has a strike length of 280 meters
and is up to 3 meters wide, although the drilling was confined to an 80 meter strike length. The
best drill intercept is 0.374 opt Au and 1.32 opt Ag over 3.0 meters. The veins are open at depth
and along strike.
The Maddux zone, close to the SG but across the Brucejack Fault is a similar zone of quartz
stockwork within a 300- by 50-meter-wide zone of quartz-sercite-pyrite altered tuff and breccia.
In 1993 two holes and 26 trenches tested the zone. The best drill intersection was 0.690 ounce
per ton gold and 1.02 ounce per ton silver over 0.65 meters.

9.0 PROJECT EXPLORATION
Granduc conducted the initial exploration of Sulphurets-Bruceside resource areas in the 1970s
and subsequently optioned the property to Esso Minerals, both carried out limited drilling.
From 1985 to 1995, the Newhawk Mines/Granduc Mines Joint Venture conducted extensive
exploration, including surface and underground drilling and sampling. Previous exploration has
been described under Section 5.0.
Silver Standard has not carried out any exploration or development work on the property since
its acquisition in 1999.
Pincock, Allen & Holt 25 9814.00d April 16, 2001
10.0 PROJECT DRILLING
Newhawk Mines has carried out all the drilling completed on the property since 1985. Both
surface and underground drilling was conducted. The West Zone outcrops at elevations ranging
from 1,380 to 1,450 meters above sea level, with a decline portal at 1,382 meters above sea
level. The West Zone deposit has been drilled at approximately 25-meter centers or less down
to 1,250 meters above sea level. From 1,259 meters above sea level to the current maximum
depth of exploration at 1,050 meters above sea level, the drill spacing widens progressively to
50 meters. The deepest development level is 1,150 meters above sea level (Figure 10-1).

11.0 SAMPLING METHODOLOGY AND APPROACH
Sampling by the Newhawk Mines/Granduc Joint Venture from 1985 to 1995 consisted of core
drilling from surface and underground, surface trenching and underground chip sampling. The
drill cores were split, with one half of the split core comprising samples with lengths of
generally 1 to 1.5 meters, but not exceeding 3.5 meters. Underground chip sampling was done
with hammer and moil in 8-inch wide strips across faces, and from opposing walls in drifts and
raises. Surface trench sampling was considered sketchy by WGM and considered by them
“only rarely adequate for use in reserves.”
Pincock, Allen & Holt 28 9814.00d April 16, 2001
12.0 SAMPLE PREPARATION, ANALYSES, AND SECURITY
In the initial stages of the Newhawk Mines/Granduc Mines Joint Venture exploration program,
samples were prepared and assayed at Newhawk’s own assay lab located in Stewart (later at the
mine-site) with approximately 10 percent of the samples checked at independent labs. As
sample volumes increased beyond Newhawk’s capacity to process them, a greater percentage
(approximately 50 percent) of the samples were sent to external independent labs. One in 20
samples was duplicated and sent to an independent lab as a check.
Samples were prepared by crushing to minus 3mm and riffling to a 300-400 g sample. Rejects
were stored. The samples were dried at 100-degrees C, cooled, pulverized to 100 percent
passing 100 mesh and rolled on a plastic mat. A standard one assay-ton fire assay procedure
with gravimetric finish was used for all assays.
Pincock, Allen & Holt 29 9814.00d April 16, 2001
13.0 DATA VERIFICATION
PAH has not collected independent samples from the property. PAH has not independently
verified the database used in the resource calculations.
Newhawk Mines had one sample in 20 duplicated at the pulverization stage and sent to an
independent lab for assaying. It is not known if blanks were included in the assay check
procedures. However, WGM states that they were satisfied that “… the sampling and assaying
has been done competently and by methods appropriate to the deposit…”
In their review of the drilling and assay database, WGM discovered a number of problems and
discrepancies. These related to inaccurate drill collar surveys, insufficient checking of data
entries and illegible entries. WGM reports that they “discovered errors which may have an
impact on individual blocks, but should not affect the estimates of larger units.”

14.0 ADJACENT PROPERTIES
Placer Dome owns the Kerr-Sulpherets Project that adjoins the Sulpherets-Bruceside property
on the west. This property was recently optioned to Seabridge Resources Inc., who report in a
press release dated June 6, 2000, that the Sulphurets gold zone contains 54.8 million tonnes
grading 1.02 g/t Au at a 0.50 g/t Au cutoff. Placer Dome has classified 72 percent of this
resource as indicated. The Kerr deposit is reported to contain 140.8 million tonnes grading 0.75
percent copper and 0.36 g/t Au at a 0.4 percent copper cutoff. Placer Dome classified 56
percent of this total resource as drill indicated. Neither zone has any direct relationship to those
of the Sulphurets-Bruceside property as referred to in this report.
Silver Standard owns 100 percent of the adjoining Snowfields Property, which was also
acquired through the acquisition of Newhawk Mines. In the June 1991 Annual Report,
Newhawk Mines reported an “in-situ resource” of approximately 7 million tons grading 0.075
opt gold. Under the current classification, this would be considered inferred mineral resources.
Because of the limited resource present from the minimal exploration to date, this property has
not been included in this report.
PAH has not verified the accuracy of the above information and the grade and tonnage of the
mineralization indicated above is not necessarily indicative of mineralization on the Sulphurets
property.
Pincock, Allen & Holt 31 9814.00d April 16, 2001
15.0 MINERAL PROCESSING AND METALLURGICAL TESTWORK
As reported in the Corona feasibility study, metallurgical testing consisted of four main sample
composites representing the West zone and the R-8 vein. The 1990 testwork was primarily
bench-scale completed at Westcoast Mineral Testing in Vancouver with some of the initial and
confirmatory tests carried out at Lakefield Research.
In summary, the testwork indicated that gold and silver recovery by a combination of gravity
separation and a flotation concentrate was optimal. Overall metal recovery (gravity and
flotation concentrate) was estimated at 89 percent for gold and 85 percent for silver in Corona’s
study. Recovery to the gravity concentrate only was 20 percent for gold and 0.4 percent for
silver.
Pincock, Allen & Holt 32 9814.00d April 16, 2001
16.0 MINERAL RESOURCES AND MINERAL RESERVE ESTIMATES
The Sulphurets-Bruceside Property has been the subject of a 1990 feasibility study (the Corona
Feasibility Study) and numerous other technical reports within which were estimates of
“mineral reserve” and “mineral resource.” There are not, however, any up to date engineering
studies using recent costs to demonstrate that the Sulphurets-Bruceside Project is currently
economically viable. As such, PAH does not consider the property to contain mineral reserves
as defined by the CIM Standards on Minerals Resources and Reserves Definitions and
Guidelines adopted by the CIM Council on August 20, 2000.
16.1 West Zone Resource Estimates
There have been several resource estimates carried out in 1989 and 1990 on behalf of Newhawk
Gold Mines Ltd., the previous owners of the Sulphurets Property.
In March 1989, Cominco Engineering reported a “geological reserve” of 216,329 tons at 0.33
opt Au and 22.77 opt Ag for the West Zone.
In March 1990, Watts, Griffis and McOuat, Consulting Geologists and Engineers, (“WGM”)
developed an “in-situ reserve” estimate for the West Zone. The WGM calculations were done
manually using Newhawk Mine’s prepared level plans aided by vertical cross sections, both
developed at 10-meter intervals. The primary assay data used by WGM was the underground
drill and channel samples.
For its “reserve” calculations, WGM used a gold-equivalent cutoff grade of 0.20 opt Au, with a
minimum true width of 1.5 meters. Silver grades were converted to gold equivalent at an
Au:Ag equivalency ratio of 1:66. PAH notes that at current metal prices (Au = $260/oz and Ag
= $4.50/oz) the Au:Ag equivalency ratio is approximately 1:58, and as such the WGM
equivalency is slightly optimistic. Blocks of waste between mineralized veins were provided
Pincock, Allen & Holt 33 9814.00d April 16, 2001
for in the estimates if those blocks exceeded 3.5 meters in horizontal dimension before dilution.
Based on scatter diagrams, and a comparison of muck samples from a raise on the R-8 vein,
WGM determined that the cutting of high-grade values was unnecessary. WGM employed a
specific gravity (SG) of 2.75 for unweathered typical core samples that had been determined by
Newhawk using the standard method of weighing samples in air and water. WGM also
estimated additional low-grade resources in the West Zone for material ranging between cutoff
grades of 0.10 opt and 0.20 opt AuEq. WGM further estimated additional potential material for
cutoff grades greater than 0.10 opt AuEq, but which were not fully delineated mineralized areas.
From their work, WGM defined “proven reserves” as mineralized material located within 7
meters of underground openings. WGM defined “probable reserves” as mineralized material
projected a maximum of 30 meters between data points in the assumed plane of the vein and a
maximum of 10 meters on the fringes of the veins, on strike or down dip. WGM defined “other
mineralization” as additional low-grade material within 30 meters of an intersection. PAH has
reclassified these “reserves” to be measured and indicated resources, in accordance with
accepted classification as defined by the CIM Standards on Minerals Resources and Reserves
Definitions and Guidelines adopted by the CIM Council on August 20, 2000.
Additional potential “reserves” included mineralization considered by WGM to be
“inadequately delineated” and is primarily the down dip projections up to a maximum of 30
meters from an intersection. PAH has reclassified these “reserves” to be inferred mineral
resources, in accordance with currently accepted classifications.
The West Zone measured + indicated resource estimate by WGM and reclassified by PAH
consists of 932,500 tons averaging 0.348 opt Au and 16.3 opt Ag. The inferred resource
consists of 51,600 tons averaging 0.187 opt Au and 8.0 opt Ag. This resource is shown in Table
16-1.

In 1990 Corona, using the WGM database, but a higher cutoff grade of 0.30 opt AuEq, reported
a diluted mineable ore reserve of 550,900 tons grading 0.418 opt Au and 18.0 opt Ag.
In 1990, Newhawk Mines updated the WGM resources after an additional underground drilling
program of 5,800 meters. Additional resources were located below the 1220 elevation on the
West zone veins and on the R8 veins on the 1050 to 1100 levels. Using the same parameters as
WGM, Newhawk Mines estimated an additional resource of 111,000 tons at 0.569 opt Au and
13.63 opt Ag. PAH checked the cross sections compiled by Newhawk and compared the
sections with those of WGM. PAH agrees with the additional resources as estimated by
Newhawk and has reclassified them to be of an indicated confidence category.
The West Zone measured + indicated resource estimate by WGM, with the Newhawk Mines
additional resource, and reclassified by PAH consists of 1,043,500 tons averaging 0.371 opt Au
and 16.0 opt Ag. The inferred resource consists of 51,600 tons averaging 0.187 opt Au and 8.0
opt Ag. This resource is shown in Table 16-2.

In 1995 Budinski quoted an in-situ geological resource of 826,000 tons grading 0.450 opt Au
and 18.8 opt Ag. This figure was derived from the addition of the WGM 1990 proven and
probable reserves plus the Newhawk 1990 additional resources.
PAH has reviewed the database and methodology used by WGM and Newhawk Mines,
including the cross sections and level plans. It is PAH’s opinion that the geologic work and the
geological model used are a reasonable representation of the mineral resource. In PAH’s
opinion the mineral resource has been prepared according to accepted industry standards using
accepted practices and that the work completed has been as thorough and as accurate as possible
given the available database.
16.2 Resource Estimate Of Other Zones
Other zones of mineralization on the Sulphurets-Bruceside Property include the Shore Zone,
SG/Maddux, Galena Hill, and Gossan Hill, as discussed in Section 8.2 (Figure 4-2, 6-2). These
other zones have been evaluated to varying degrees by diamond drilling and trenching.
Budinski (1995) reported resources from previous estimates for the five satellite showings to be
198,500 tons grading 0.570 opt Au and 3.95 opt Ag. PAH reviewed the drilling data, plans and
cross-sections and reclassified these resources to be in accordance with accepted classification
Pincock, Allen & Holt 36 9814.00d April 16, 2001
as defined by the CIM Standards on Minerals Resources and Reserves Definitions and
Guidelines adopted by the CIM Council on August 20, 2000.
The Shore Zone mineral resource was estimated by Newhawk Mines (Vulumiri, 1989). PAH
found that the data for the Shore Zone was the most complete of the other zones. Cross
sections, level plans and longitudinal sections were available. Two shoots carry 70 percent of
the resource. A cutoff grade of 0.2 opt AuEq was used. Specific gravity used for the Shore
Zone estimation appears to be 3 gm/cm3 rather than the 2.75 gm/cm3 used for the West Zone.
PAH believes that this may overstate the resource tons and ounces by approximately 10 percent.
Furthermore, the cross sections show that some of the sample lengths were up to 4 meters
within mineralized quartz zones. PAH has reclassified the Shore Zone mineralization to be an
indicated resource, in accordance with currently accepted classifications. The Shore Zone
resource consists of 92,300 tons averaging 0.371 opt Au and 4.6 opt Ag.
The remainder of the other zones were estimated by Newhawk Mines (Visage, 1993) using a
0.20 opt AuEq cutoff grade (based on a Au:Ag equivalency ratio of 1:85) and a minimum width
of 1.5 meters. PAH notes that this ratio is 30 percent greater than the Au:Ag equivalency ratio
of 1:66 used by WGM in the West Zone and as such PAH believes that the equivalency is
somewhat optimistic. A 2.75 gm/cm3 density was applied to convert estimated volumes into the
resource tons estimate.
Gold and silver resource grades for the other zones were estimated mainly from fire assays, with
metallic screen assays used where available. Sample check assays were averaged together with
the original assay for estimation. High-grade statistical outlier grades were not cut for the
resource grade estimate. No statistics appear to have been carried out on the advisability of
cutting the high-grade gold values. Newhawk indicates that cutting the high grade gold values
to 1 ounce in the PM-4A vein in the Gossan Hill Zone reduces the gold grade from 3.390 opt to
0.420 opt Au. Similarly, in the Galena Hill Zone the grade drops from 0.784 opt to 0.381 opt
Au.
Pincock, Allen & Holt 37 9814.00d April 16, 2001
The other satellite zones measured + indicated mineral resource estimate by WGM and
Newhawk Mines and reclassified by PAH consists of 92,300 tons averaging 0.371 opt Au and
4.6 opt Ag. The inferred resource consists of 99,700 tons averaging 0.725 opt Au and 3.5 opt
Ag. This resource is shown in Table 16-3.

16.3 Total Sulphurets-Bruceside Property Resource Estimate
Based on the previous work by other independent consultants, the Sulphurets-Bruceside
Property contains a measured and indicated mineral resource of 1,135,800 tons at a grade of
0.371 opt Au and 15.1 opt Ag, and an additional inferred mineral resource of 151,300 tons at a
grade of 0.542 opt Au and 5.0 opt Ag. Using an Ag: Au ratio of 55:1, this amounts to a
measured + indicated resource of 40.3 million ounces of AgEq and an inferred resource of 5.2
million ounces of AgEq. This resource is shown in Table 16-4.

17.0 OTHER RELEVANT DATA AND INFORMATION
Although not a development property as defined by NI 43-101, the Sulphurets-Bruceside
property has been the subject of a prior engineering study that included metallurgical testwork.
In October 1990, Corona Corporation completed a study entitled “Sulphurets Project Feasibility
Study.” This study contemplated an underground mine with decline access. Material mined
from underground would be transported to a nominal 350 ton-per-day surface mill facility for
processing. The proposed mill consisted of a crusher(s), a ball mill, gravity and flotation
circuits, dewatering, and a smelting unit for producing a gold-silver doré bar. Tailings would be
deposited in Brucejack Lake. Operating costs were estimated to be $145 per ton. Based on a
capital cost of $42.7 million, which included working capital and a 15 percent contingency and
a gold price of US$400 and silver at US$5, the discounted cash flow rate of return was 6.7
percent.
Pincock, Allen & Holt 40 9814.00d April 16, 2001
18.0 INTERPRETATION AND CONCLUSIONS
Previous owners have carried out extensive exploration and development programs during the
years 1980-1995, consisting of mapping, trenching, underground development, surface and
underground diamond drilling. A feasibility study was completed in 1990.
Based on the previous work, the Sulphurets-Bruceside property contains a measured and
indicated mineral resource of 1,135,800 tons at a grade of 0.371 opt Au and 15.1 opt Ag and an
additional inferred mineral resource of 151,300 tons at a grade of 0.542 opt Au and 5.0 opt Ag.
Based on an Ag:Au equivalency ratio of 55:1, this amounts to a measured + indicated resource
of 40.3 million ounces of AgEq and an inferred resource of 5.2 million ounces of in-situ AgEq.
It is PAH’s opinion that the estimation of the mineral resources as stated above and shown in
Table 16-4 has been prepared according to accepted industry standards using accepted practices,
and that the work completed has been both thorough and as accurate as possible given the
available database. It is PAH’s opinion that the classification of measured, indicated and
inferred mineral resources as estimated herein, meet the definitions of measured, indicated and
inferred mineral resources as stated by NI 43-101 and defined by the CIM Standards on Mineral
Resources and Reserves Definitions and Guidelines adopted by the CIM council on August 20,
2000.
The property is considered to have potential for additional resources both at depth in the veins
explored to date and in other targets that have yet to be fully delineated. Because of the isolated
location of the property, higher gold and silver prices are required before further exploration
programs are recommended.
Pincock, Allen & Holt 41 9814.00d April 16, 2001
19.0 RECOMMENDATIONS
No further work is recommended on the properties at the present time. Further exploration
should await higher gold and silver prices.
