10 FSE:61M | OTCQB: IMAHF | TSX.V: IMA MINING & METALLURGY

11 FSE:61M | OTCQB: IMAHF | TSX.V: IMA Simple, Low Cost Mining

“Ore” is a fine white clay-like sand created by the weathering of a granodiorite body.

Weathering takes place to depths of 75 to 200 feet; little overburden, shallow pits.

Ore is excavated without drilling or blasting using contract miners utilizing 3 yd3 excavator and 30 ton trucks.

Short haul to process facility -10 minute cycle time; mining during daylight hours only.

Mining Costs $14.50 / ton product $9.00 per ton of “ore”

12 FSE:61M | OTCQB: IMAHF | TSX.V: IMA Separation Techniques proven at Ginn and MRL Pilot Plants

1. Wet Screen separation clay washed from Sand * 2. Quartz K-Spar Sand Fraction • K-spar is floated; quartz sunk via basic flotation • Quartz fraction is ground finer and then re-floated TrueQ1 product, re-floated up to 2 more times to remove residual K- spar to make high purity quartz products (TrueQ3)

3. Kaolinite Halloysite Clay Fraction • Halloysite is separated from kaolinite with hydro-cyclones and centrifuge • Proprietary flotation +90% halloysite product • Halloysite slow dried to preserve tubular shape • Kaolin calcined (heated to 8500C - 9000C) to make Metakaolin

Processing costs $58.50/t product; $36/t “ore” * recent testing of hydro-cyclones for initial cut improves results see August 23, 2017 news release

13 FSE:61M | OTCQB: IMAHF | TSX.V: IMA Permitting

• Water use permit approved by IDWR • The Idaho Department of Lands, the lead permitting agency has approved the Company’s Operation and Reclamation Plan. Subject to placing of required bonding, I-Minerals is authorized to commence mining operations. • Good environmental stewardship was incorporated into the project layout including dry stacking of the tailings and a zero water discharge operation. • Minor additional permitting required such as air discharge requires identification of specific calciner. • Bonding needs to be in place to begin construction. I-Minerals evaluating land swap where in it would ultimately own the surface rights as a means to reduce bonding requirements.

Avg. Annual OPEX $19.1m

17 FSE:61M | OTCQB: IMAHF | TSX.V: IMA Market Entry Assumptions at Start Up

• Halloysite – best global deposit of significance suitable for life science applications and replaces more expensive materials. Users have indicated willingness to pay 3-5 times FS price. No reason to constrain average in FS

• K-spar – by far the highest K2O feldspar available in North America. Priced comparable with inferior incumbent producer. Sales of high quality Spanish K-spar at high prices generated weak volume. CAP at +10% FS • Metakaolin – only producer in the Pacific Northwest. Georgia Metakaolin +$250/t with transport cost +$200 = too expensive. Fly ash currently used, but it is an inconsistent pozzolan in short supply. CAP at +10% FS • Quartz – highly competitive markets in the Commodity grade space = IMA a price taker and difficult markets to penetrate in the high purity end until quality proven at production. If assume limited HPQ market penetration in early years and large volumes sold under contract into glass markets CAP at - 50% FS

18 FSE:61M | OTCQB: IMAHF | TSX.V: IMA Startup EBITDA vs Mineral Price Analysis Quartz held at -50% of FS; K-spar Metakaolin capped +10% of FS

19 FSE:61M | OTCQB: IMAHF | TSX.V: IMA EBITDA Growth Opportunities after Start Up

• FS Plant design has ~10% increased production capacity • Fine grind K-spar and quartz products generate a higher price per ton for a comparatively small marginal cost. (e.g. 30 mesh K-spar $230/t; 200 mesh K-spar $270 per ton; grinding costs <$10/t) • Plant floor plan has open space for additional grinding capacity • New TrueQ3 sales. Feedstock to group with leach capability and capacity. Make products for markets at $500-$1000/t • Consistent TrueQ3 production quality opens door for customers to switch from current high cost duopolistic suppliers. • ULTRA HalloPure flotation capacity at 75% utilization in FS • Change the customers to generate most profitable product mix.
