Brucejack Project – Technical SessionFebruary 2014
CAUTIONARY STATEMENT
Forward Looking Information
This Presentation contains “forward-looking information” and “forward looking statements” within the meaning of applicable Canadian and United States securities legislation. Forward-looking information may include, but is not limited to, the preliminary mill results from processing the 426585E cross-cut, the preliminary mill results from the bulk sample program, the estimated gold to be produced from the bulk sample program, the estimated contained gold in the 426585E cross-cut from the sample tower, the anticipated production and developments in our operations in future periods, information with respect to our planned exploration and development activities, the adequacy of our financial resources, the estimation of mineral reserves and resources including the 2013 Valley of the Kings Mineral Resource estimate, realization of mineral reserve and resource estimates and timing of development of our Brucejack Project, costs and timing of future exploration, results of future exploration and drilling, production and processing estimates, capital and operating cost estimates, timelines and similar statements relating to the economic viability of the Brucejack Project, timing and receipt of approvals, consents and permits under applicable legislation, our executive compensation approach and practice, the composition of our board of directors and committees and adequacy of financial resources. Wherever possible, words such as “plans”, “expects”, “projects”, “assumes”, “budget”, “strategy”, “scheduled”, “estimates”, “forecasts”, “anticipates”, “believes”, “intends”, “targets” and similar expressions or statements that certain actions, events or results “may”, “could”, “would”, “might” or “will” be taken, occur or be achieved, or the negative forms of any of these terms and similar expressions, have been used to identify forward-looking statements and information. Statements concerning mineral reserve and resource estimates may also be deemed to constitute forward-looking information to the extent that they involve estimates of the mineralization that will be encountered if the property is developed. Any statements that express or involve discussions with respect to predictions, expectations, beliefs, plans, projections, objectives, assumptions or future events or performance are not statements of historical fact and may be forward-looking information. Forward-looking information is subject to a variety of known and unknown risks, uncertainties and other factors that could cause actual events or results to differ from those expressed or implied by the forward-looking information, including, without limitation, those risks identified in our Annual Information Form dated March 18, 2013 filed on SEDAR at www.sedar.com and in the United States on Form 40-F through EDGAR at the SEC’s website at www.sec.gov. Forward-looking information is based on the expectations and opinions of our management on the date the statements are made. The assumptions used in the preparation of such statements, although considered reasonable at the time of preparation, may prove to be imprecise. We do not assume any obligation to update forward-looking information, whether as a result of new information, future events or otherwise, other than as required by applicable law. For the reasons set forth above, prospective investors should not place undue reliance on forward-looking information.
National Instrument 43-101
Technical and scientific information contained herein relating to the Projects is derived from National Instrument 43-101 (“NI 43-101”) compliant technical reports (“Reports”) “Mineral Resources Update Technical Report” dated December 19, 2013 and “Feasibility Study and Technical Report on the Brucejack Project, Stewart, BC” dated June 21, 2013. We have filed the Reports under our profile at www.sedar.com. Technical and scientific information not contained within the Reports for the Projects have been prepared under the supervision of Mr. Kenneth C. McNaughton, P.Eng. and Ian Chang, P.Eng., each of whom is an independent “qualified person” under NI 43-101.
This presentation uses the terms “measured resources”, “indicated resources” (together “M&I”) and “inferred resources”. Although these terms are recognized and required by Canadian regulations (under NI 43-101), the United States Securities and Exchange Commission does not recognize them. 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, title, taxation, socio-political, marketing, or other relevant issues. There is no guarantee that all or any part of the mineral resource will be converted into mineral reserves.
In addition, “inferred resources” have a great amount of uncertainty as to their existence, and economic and legal feasibility. It cannot be assumed that all or any part of an inferred mineral resource will ever be upgraded to a higher category. Under Canadian rules, estimates of inferred mineral resources may not form the basis of feasibility or pre feasibility studies, or economic studies, except for a Preliminary Assessment as defined under NI 43-101. Investors are cautioned not to assume that part or all of an inferred resource exists, or is economically or legally mineable.

Indicator Kriging
Indicator Kriging is a common technique
— Originated out of Stanford University (Journel, 1983)
— Non-parametric
— Not a linear technique
— Suitable for skewed and mixed statistical datasets
As in all resource estimation methods, it can be applied
poorly – care is required
The definition of geological domains is still important

(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 reported 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 and tonnes figures in totals may differ due to rounding.
(4) The Mineral Resource estimate stated in Table 14.25 and Table 14.26 is defined using 5 m by 5 by 5 m blocks in the well drilled portion of West Zone
(5 m by 10 m drilling or better) and 10 m by 10 m by 10 m blocks in the remainder of West Zone and in VOK.

Key Points – December 2013
Mineral Resource estimate
48
Confirms global robustness of November 2012 estimate – little changed
― M&I contained metal effectively the same
― More selective estimate (slightly higher grade for slightly less tonnes)
Conservative
― Drilling orientation under-sampling N-S structures
― Revised estimation parameters calibrated to production
Increased Confidence
― Reconciliation to production data
― Definition of Measured Mineral Resource
― Increased understanding of mineralization
― Confirmation of geological model
WHY LONGHOLE STOPING AT BRUCEJACK?
Longhole Open Stoping (LHOS) selected at Brucejack because:
Vein stockwork conducive to bulk mining
Steeply dipping orebody
Extensive orebody
Probable reserves over:
― >550 m of vertical extent in VOK
― >450 m of strike length
― Inferred resource beyond those limits

OTHER REASONS LHOS IS SUITABLE
Stable rock in ore, hangingwall, and footwall
Adaptable to a variety of stope widths
Allows for scheduling flexibility due to multiple stopes on multiple horizons being available
Conventional mining method and equipment
High production rate provides lower operating costs
Backfill placement helps to maximize recovery of the reserve and reduce surface impacts

Primary stopes bounded by rock on both sides
Secondary stopes bounded by backfill on one or both sides
30 m level spacing
Maximum of 45 m stope lengths
15 m widths
TOP CUT CENTER DRIVE
56
The mucking level was previously established during the excavation of the previous stope
A drift is driven across the center of the drift using a jumbo drill
Two Boom Jumbo
CENTER DRIVE CABLE BOLTING
57
The center of the stope is supported using cable bolts in ordered to provide a stable span after the stope is fully excavated
Cable Bolter
SLASHING COMPLETE
58
Full width slashing allows for parallel drilling rather than ring drilling
Parallel drilling provides cleaner walls which helps to control dilution and improve recovery
SLOT RAISE DRILLING
59
Because the stope is confined by rock on all sides, an opening must be excavated to allow rock movement and volume swell during the blasts
Accomplished by excavating a slot raise, then a full width slot
Several methods of accomplishing this
Now viewing from the hanging wall
SLOT DRILLING
60
Once the slot raise is complete, the slot is drilled off
The drilling is completed using a long hole drill
Long Hole Drills
PRODUCTION BLASTING
61
Once completed, the more efficient production blasting can begin
The production blasts are shot into the void created by the slot
Again, the ore is mucked from the lower level using remote control LHD’s
FILL BARRICADE CONSTRUCTED
62
Once the stope is fully mucked out, a fill barricaded is constructed
The barricade prevents backfill from running into the level before it has cured
Viewing from the footwall
BACKFILL PLACEMENT
63
High strength mucking sill pour provides a harder surface for mucking the next stope up
Reduces ore losses from LHD’s driving over ore
Reduces dilution from the LHD bucket digging up backfill

APPENDIX: CLEOPATRA STRUCTURE
76
The Cleopatra structure is considered as being part of the broader stockwork mineralization system:
― No obvious cross-cutting relationships
― Dominant E-W and subordinate N-S structures appear to merge
― No differences in style of mineralization, gangue mineralogy, and associated alteration between the E-W and N-S components of the stockwork system
― Similar abundance of dendritic electrum in both E-W and N-S structures
― Both E-W and N-S structures appear to have formed coevally – imprinted on rocks of Lower Jurassic age, cut by post-mineral dykes of Lower Jurassic age
― Both E-W and N-S structures display similar styles and degrees of deformation
The presence of N-S structures in the stockwork is not unexpected:― Both the dominant E-W and subordinate N-S structures are present throughout
the bulk sample area, as well as in surface outcrop
The Cleopatra structure is interpreted as one of probably a whole series of variably oriented higher fluid flow conduits in the overall stockwork system
