ASX: PXX www.polarx.com.au High grade Cu-Au in the Alaska Range Project Investor Presentation, 11 February 2019 1
High-Grade Cu-Au-Ag deposits with a clear and rapid growth strategy ➢ Advanced project in Alaska with district-scale copper anomalies and high-grade JORC resources in an under- explored, world-class porphyry province ➢ Two goals: 1. Expand the high grade Zackly Cu-Au-Ag resource to critical-mass for an economically viable project which will underwrite a robust and tangible Company valuation 2. Advance high ranking porphyry Cu-Au targets at Mars and Saturn to a major new discovery through drilling High grade copper sulphides (bornite) in Zackly core 2 cm 2

Alaska is low risk: Under-explored TIER 1 geology in a TIER 1 jurisdiction ➢ TIER 1 geology with 6 current mines, all world class ➢ Several new world class deposits in permitting and feasibility study phase ➢ Over 40Moz Au mined to date ➢ Considerably under-explored compared to other TIER 1 provinces – new deposits are still being found at surface ➢ AA jurisdiction (2018 Global Risk Review) ➢ Strong Australian presence in major projects: ❑ Northern Star acquisition of Pogo (Au) ❑ South32 investment in Trilogy (Cu, Co) ❑ Sandfire investment in Whiterock (Zn, Ag) ALASKA RANGE PROJECT is in a good location: ➢ 250km due north-east of Anchorage, <6 hours by road ➢ Nearby lodges for accommodation & support ➢ Easy road/rail access to all year ports 4
Superb geology in an under-explored world class province ➢ LOW RISK - existing high-grade JORC resources with MARS upside: 3.4Mt @ 1.2% Cu, 2.0g/t Au, 14.0g/t Ag ➢ Zackly Skarn ➢ Caribou Dome 2.8Mt @ 3.1% Cu ➢ GOAL 1: Potential for rapid resource expansion at Zackly ➢ Low exploration risk due to magnetic nature of mineralization which can be directly imaged ➢ Recent near-surface, high-grade, flat lying intersections open in all directions (e.g. 55m @ 2.8g/t Au + 0.6% Cu) ➢ GOAL 2: Evidence for presence of large porphyry systems: ➢ Strong geochemical anomalism in Cu, Au, As, Mo (classic porphyry pathfinder elements) associated with a geophysical target at Mars ➢ Strong vectors from Zackly mineralization and ZACKLY alteration which increases in intensity towards Saturn* ➢ Magnetic anomalies with porphyry style signatures at both Mars and Saturn * Previously known as the Zackly SE target 5
Alaska Range at the intersection of two major crustal-scale faults ➢ Straddles the major structure between the Tintina Gold Belt and the main Porphyry Cu- Au Belt in Alaska-Yukon-British Columbia ➢ Intersected by a major NW crustal-scale fault which contains known porphyry systems at its southern end ➢ Highly anomalous copper levels in regional soil sampling data ➢ Prominent WNW trending structural corridor hosts mineralization at Zackly and Mars 6
12km long mineralised corridor provides near term growth and upside ➢ Zackly skarn likely to rapidly increase in size with further drilling around near-surface, flat lying mineralization in drill holes ZX-18020/24 ➢ Mars porphyry target has anomalous Cu-Au-Mo-As 55m @ 2.8g/t Au + 0.6% Cu geochemistry and 47m @ 3.1g/t Au + 0.6% Cu geophysical anomalies 15m @ 2.2g/t Au + 2.3% Cu consistent with target type 9.3m @ 2.3g/t Au + 3.3% Cu ➢ Saturn comprises blind geophysical target under 15-20m glacial till – magnetic signature consistent with porphyry system 3.4Mt @ 2.0g/t Au + 1.2% Cu 7
Zackly – drilling adds high grades 850m east of current resource boundary Cut-off grade Category Million Tonnes Cu % Au g/t Ag g/t Contained Cu Contained Cu Contained Au Contained Ag (t) (Mlb) (oz) (Moz) 0.5% Cu Inferred 3.4 1.2 2.0 14.0 41,200 90.9 213,000 1.5 ➢ 2017 drilling verified historical data leading to JORC resource estimate in early 2018 ➢ 2018 drilling has extended mineralization below existing resource ➢ 2018 drilling extended resource to the east ➢ Potential to significantly increase resource size with further drilling 8
Zackly – existing resource is high grade Cu-Au-Ag, open at depth ➢ Sub-vertical, suitable for underground mining methods ➢ Copper mineralization dominated by high-tenor bornite and chalcocite which may yield a high grade concentrate ➢ Coarse-grained, free-milling gold present ➢ Metallurgical studies to commence in Q1 2019 9
Zackly – rapid growth potential to the east ➢ Change in orientation across fold hinge, visible in the magnetic data ➢ Thick, shallow, gently dipping mineralization – open pit potential ➢ Clear potential to rapidly expand resource through further drilling Overturned fold, thickening in hinge 10
Saturn porphyry Cu-Au target ➢ New (blind) target generated from re-processing regional magnetic data ➢ Recent high-resolution aeromagnetic data validates target ➢ Multiple lines of evidence to support porphyry target: ➢ Interpreted to comprise a cluster of oxidized intrusions ➢ Surrounded by a zone of intense magnetite destruction ➢ Nearby skarn mineralization (Zackly) as proof of process ➢ Strong vectors from Zackly mineralization with Zackly grades, thickness and intensity of alteration deposit increasing from west to east Saturn target 11
Mars: strong magnetic and surface geochemical anomalism (Cu-Au-As-Mo) Magnetic data (Analytical signal) Copper in soil anomalism 1400m 12
Mars: strong rock-chip geochemistry, up to 50% copper and 7g/t gold Gold in rock-chips on gold in soil anomaly Copper in rock-chips on copper in soil anomaly 13
Mars: co-incident magnetic, IP and Cu-Au-As-Mo anomalism, drill ready 14
Caribou Dome – very high copper grades, open in all directions ➢ 2.8Mt at 3.1% copper (0.5% lower-cut) for 86,000t of contained Copper (JORC 2012) ➢ 60% in the top 150m including 935,000t @ 4.4% in possible open pit ➢ High grade, sediment-hosted massive sulphide lenses, open in all directions ➢ Many un-tested IP and soil anomalies within 1-5km ➢ All within economic trucking distance of Zackly High priority IP targets on image of copper in soil anomalism 15
