Forward looking information contained in this presentation includes, but is not limited to, statements with respect to: (i) the estimation of inferred and indicated mineral resources; (ii) the success of exploration activities; (iii) the results of the PEA including statements about future production, future operating and capital costs, the projected IRR, NPV, payback period, and production timelines for the Tiger Deposit. These statements are based on information currently available to ATAC Resources Ltd. ( ATAC ) and ATAC provides no assurance that actual results will meet management's expectations. In certain cases, forward-looking information may be identified by such terms as "anticipates", "believes", "could", "estimates", "expects", "may", "shall", "will", or "would". Forward-looking information contained in this presentation is based on certain factors and assumptions regarding, among other things, the estimation of mineral resources, the realization of resource estimate, gold metal prices, the timing and amount of future exploration and development expenditures, the estimation of initial and sustaining capital requirements, the estimation of labour and operating costs, the availability of necessary financing and materials to continue to explore and develop the Tiger Deposit in the short and long-term, the progress of exploration and development activities, the receipt of necessary regulatory approvals, the completion of the environmental assessment process, and assumptions with respect to currency fluctuations, environmental risks, title disputes or claims, and other similar matters. While ATAC considers these assumptions to be reasonable based on information currently available to it, they may prove to be incorrect. Forward-looking information involves known and unknown risks, uncertainties and other factors which may cause the actual results, performance or achievements of ATAC to be materially different from any future results, performance or achievements expressed or implied by the forward-looking information. Such factors include risks inherent in the exploration and development of mineral deposits, including risks relating to changes in project parameters as plans continue to be redefined including the possibility that mining operations may not commence at the Tiger Deposit, risks relating to variations in mineral resources, grade or recovery rates resulting from current exploration and development activities, risks relating to changes in gold prices and the worldwide demand for and supply of gold, risks related to increased competition in the mining industry generally, risks related to current global financial conditions, uncertainties inherent in the estimation of mineral resources, access and supply risks, reliance on key personnel, operational risks inherent in the conduct of mining activities, including the risk of accidents, labour disputes, increases in capital and operating costs and the risk of delays or increased costs that might be encountered during the development process, regulatory risks, including risks relating to the acquisition of the necessary licenses and permits, financing, capitalization and liquidity risks, including the risk that the financing necessary to fund the exploration and development activities at the Tiger Deposit may not be available on satisfactory terms, or at all, risks related to disputes concerning property titles and interest, and environmental risks. This list is not exhaustive of the factors that may affect any of ATAC's forward-looking information. These and other factors should be considered carefully and readers should not place undue reliance on ATAC's forward-looking information. ATAC does not undertake to update any forward-looking information that may be made from time to time by ATAC or on its behalf, except in accordance with applicable securities laws. PEA DISCLOSURE It should be noted that the Tiger Deposit PEA is preliminary in nature and includes inferred mineral resources that are considered too speculative geologically to have the economic considerations applied to them that would enable them to be categorized as mineral reserves. There is no certainty that the PEA forecast will be realized or that any of the resources will ever be upgraded to reserves. Mineral Resources that are not Mineral Reserves do not have demonstrated economic viability. Additional information about the Tiger Deposit PEA is summarized in ATAC s May 31, 2016 technical report titled Technical Report and Preliminary Economic Assessment for the Tiger Deposit, Rackla Gold Project, Yukon, Canada which can be viewed at www.sedar.com under the ATAC profile or on the ATAC website at www.atacresources.com. QUALIFIED PERSON Julia Lane, B.Sc., P.Geo., the Vice President of Exploration of ATAC, is a qualified person for the purposes of National Instrument 43-101. All technical information contained in this presentation has been approved by Julia Lane. TRUE WIDTHS True widths for all Conrad, Osiris, Sunrise, Ibis, Anubis, Tiger and Ocelot highlight diamond drill holes are estimated to be 30% - 100% of intersected widths. RAB drill hole intersections are drilled thicknesses and true widths are unknown. Orion diamond drilling true thicknesses are also unknown at this time. 1

CONRAD ZONE

CONRAD ZONE Previous Exploration Conrad is the most advanced zone in the Nadaleen Trend and received 43,433 m of diamond drilling in 108 holes between 2010-2015 Previous shallow drilling focused on developing the Conrad Upper Zone along the crest of an anticlinal fold where a strike length of 800 m has been defined Limited drilling beneath the Upper Zone has defined an area of mineralization proximal to a laterally extensive, near vertical siltstonelimestone contact at the Conrad Middle Zone only 300 m of the 800 m long favourable contact has been tested 2017 Exploration Plans Diamond drilling will focus on crosscutting faults thought to be associated with highgrade gold mineralization intersected in proximity to the 350 and 650 faults Only limited drilling has tested the 350 and 650 faults due to their near parallel orientation to previous drilling Diamond drilling will also test the Conrad Lower Zone along strike of OS-14-230 which intersected 42.67 m of 3.03 g/t gold and 21.71 m of 3.15 g/t gold OS-12-114: 42.93 m of 18.44 g/t gold Limited drilling has tested for mineralization at the Conrad Lower Zone, opening up an entirely new area for exploration The average grade of all reported intersections at Conrad is 4.75 g/t gold* Out of 148 released Conrad intersections, the minimum intersection grade was 1.01 g/t gold and the maximum was 18.44 g/t gold. The minimum interval width of intersections was 2.20 m and the maximum was 124.96 m 25

OSIRIS ZONE 26

OSIRIS ZONE Previous Exploration The Osiris Zone was ATAC s first discovery of Carlin-type gold mineralization and hole OS-10-001 intersected 65.20 m of 4.65 g/t gold Osiris received 14,220 m of diamond drilling in 59 holes between 2010-2012 Previous diamond drilling focused on the hinge of an anticline fold and along strike where shallow drilling traced mineralization over a 900 m strike length 2017 Exploration Plans Diamond drilling will focus on the northern extension of Osiris along strike of OS-11-080 and OS-11-082 which intersected 19.81 m of 5.07 g/t gold and 44.20 m of 4.41 g/t gold, respectively RAB drilling will test additional high-grade mineralized structures similar to the North Osiris Trench which returned values up to 80.40 g/t gold over 1.8 m** The average grade of all reported Osiris intersections is 3.62 g/t gold* Out of 55 released Osiris intersections, the minimum intersection grade was 1.36 g/t gold and the maximum was 8.37 g/t gold. The minimum interval width of intersections was 3.05 m and the maximum was 65.20 m ** See ATAC news release dated August 30, 2011 for further details 27

SUNRISE ZONE 14

IBIS ZONE

SUNRISE & IBIS ZONES Previous Exploration Sunrise is located 300 m east of the Osiris anticline and received 4,328 m in 19 holes between 2012-2014 Mineralization at Sunrise occurs as subparallel tabular bodies that dip steeply south and drilling to date outlined a 215 m strike length that is open along strike and past a depth of 350 m The average grade of all reported Sunrise intersections is 6.25 g/t gold* Ibis is located 550 m southwest of the Sunrise Zone and received 6,574 m in 26 holes between 2011-2013 2017 Exploration Plans Shallow RAB and diamond drilling at Sunrise will focus on following the mineralized corridor along strike to the west where OS- 12-150 intersected 15.24 m of 2.64 g/t gold There are 3 untested gold-in-soil anomalies to the north and east of where previous drilling intersected the main Ibis zone select rock samples within these anomalous areas grade: 1.30 g/t gold, 1.81 g/t gold, 2.46 g/t gold, and 3.15 g/t gold these anomalies will be tested by RAB drilling in 2017 Sunrise OS-13-217: 16.76 m of 6.76 g/t gold Much like at Osiris and the Conrad Upper Zone, mineralization at Ibis is best developed in the crest of an anticline where mineralization has been traced through drilling for an unfolded strike length of 230 m The average grade of all reported Ibis intersections is 3.10 g/t gold** Out of 17 released Sunrise intersections, the minimum intersection grade was 2.03 g/t gold and the maximum was 11.95 g/t gold. The minimum interval width of intersections was 1.05 m and the maximum was 19.81 m ** Out of 18 released Ibis intersections, the minimum intersection grade was 1.02 g/t gold and the maximum was 6.28 g/t gold The minimum intersection width of intersections was 3.32 m and the maximum was 51.82 m 30
