In-Pit Mineral Resource Estimate
The Eagle Mineral Resource update within an updated resource pit constraint resulted in a 21.1% increase in Measured and Indicated (“M+I”) gold ounces as well as a 0.6% increase in gold grade. This Resource update includes all Eagle and Eagle proximal drilling completed post the 2016 Feasibility Study (“FS”), 58 new core holes.
This first principles re-estimation of the Eagle gold domain and grade further validates the Eagle model and results in increased gold grade, tonnage and total gold ounces. The Mineral Resource increased 766,000 oz Au in the M+I categories.

Updated Eagle Resource Model Discussion
The Eagle Resource was updated with the additional drilling performed post the 2016 Eagle Feasibility Study, see Company News release of December 5, 2018 for full details of updated resource.
The drillhole database of the Eagle Gold Mine used for this Resource update has a cut-off date of October 8, 2017. It is comprised of 1,078 holes with 178,490m of drilling and 112,949 assays for gold.
The geology model of the Eagle Zone was built as a mineralized envelope with a cut-off grade of 0.15 g/t Au. This model was built from first principles without influence of previous modelling, and utilized the drillhole database of gold grades. Interpretations of gold mineralization limits were performed on north-south sections spaced at 25m intervals. From the interpretation and the modelling of the mineralized zone, it was observed that the orebody has a consistent geometry that is continuous from one section to the next.
The estimation of gold grades was performed with the ordinary kriging technique on capped composites. The block model structure consists of an orthogonal model (no rotation) with block dimensions of 10m (X) x 10m (Y) x 5m (Z) with specific gravity (SG) values based on lithology, and reduced oxidation state. A minimum of 2 and maximum of 12 samples were required to calculate a block estimate. The search ellipsoid was dimensioned and oriented according to the variogram models. The grade estimation process consisted of a 3-pass approach with the parameters of the first pass (long axis 80°/0° at 56.0m; short axis 170°/0° at 25.0m; vertical axis 80°/-90° at 75.0m). The estimation parameters of the second and third passes are the same with the exception of an enlarged search ellipsoid by 1.5 times and 3 times the dimensions from the first pass, respectively. Only blocks within the modeled mineralized zone were estimated.
The mineral resource was classified as Measured, Indicated, and Inferred based on the variogram ranges of the second structures. The average distance of samples from the block center was utilized as the classification criterion. Measured, Indicated, and Inferred Resources were assigned to the estimates of the Eagle Zone. The distances to categorize the resources into the different classes were Measured (≤ 17.0m), Indicated (> 17.0m and ≤ 52.0m) and Inferred (>52.0m).
Mineral Reserves
The Proven and Probable Mineral Reserve Estimate is the economically minable portions of the Measured and Indicated in-pit Mineral Resource as demonstrated by the updated Technical Report.
The Mineral Reserves were developed by examining each deposit to determine the optimal and practical mining method. Cut-off grades were then determined based on appropriate mine design criteria and the adopted mining method. A shovel and truck open pit mining method was selected for the two deposits.
The mineral reserve estimations take into consideration on-site operating costs (mining, processing, site services, freight, general and administration), geotechnical analysis for open pit wall angles, metallurgical recoveries, and selling costs. In addition, the Mineral Reserves incorporate allowances for mining recovery and dilution and overall economic viability.
The estimated Proven and Probable Mineral Reserves is shown in Table 4.

Mining
Eagle and Olive are open pit mines and operate as drill, blast, shovel and haul operations with a mine life of 11 years. Crushed ore is hauled to the primary crusher located toward the north east side of the Eagle pit. Run of mine (“ROM”) ore will be hauled directly to the primary heap leach pad.
Eagle waste rock is hauled to one of two waste rock storage areas immediately to the south and north of the open pit which results in short haul distances. Olive waste rock will be hauled to a waste rock storage area immediately south-west of the open pit. Waste rock storage will be managed to allow for future pit expansion. The ratio of waste to ore is 0.96 to 1 and total waste material is 149 million tonnes.
Processing
Material above crushed ore cut-off grades is hauled from the open-pits to the primary crusher. Ore is primary crushed at a nominal rate of 29,500 tpd. Following primary crushing, ore is conveyed through a secondary and tertiary crushing circuit to a final crush size of P80 6.5 mm. Crushed ore is conveyed to one of the two in-valley heap leach pads.
Ore is stacked in 10m high lifts using a mobile conveying and stacking system then primary leached for 45 days. The pregnant solution, laden with gold once leaching is complete, is pumped to an Adsorption Desorption Recovery (“ADR”) plant where gold is stripped from the solution and poured into doré bars. Life of mine recovery is estimated at 76%.
Ore will be mined and primary crushed 365 days per year. Ore is stacked on the heap leach pads 275 days per year. A primary crushed ore stockpile will be used during the coldest 90 days of the year and the stockpile will be reclaimed to the secondary crushing circuit and loaded onto the pads during the 275 day stacking period.
A total of 155 million tonnes of ore will be mined, including 121 million tonnes of crushed ore and 35 million tonnes of ROM ore.
Infrastructure
The project is well supported by local infrastructure. Eagle is accessed via an existing year-round road connecting to the Silver Trail Highway. The Eagle Gold Mine is connected to grid power with a long-term power purchase agreement with Yukon Energy Corp. A 1,400m airstrip is located in Mayo, approximately 85km by road from the project site, with daily scheduled commercial flights. An existing camp and all supporting infrastructure is in place and supporting mine and processing operations.
Initial Capital Cost
The initial capital cost for Eagle is sunk and more fully described in the Technical Report.
Sustaining Capital Cost Estimate
Life of Mine sustaining capital costs are estimated at $174.5 million and closure costs are $35 million.
