I-Minerals' Pilot Plant Work Update; Presenting at 2017 Marcum MicroCap Conference

VANCOUVER, BC --(Marketwired - June 14, 2017) - I-Minerals Inc. (TSX VENTURE: IMA) (OTCQB: IMAHF) (FRANKFURT: 61M) (the "Company") is pleased to provide an update on the ongoing pilot plant work at Ginn Mineral Technologies ("GMT") in Sandersville Georgia. Additional pilot plant work is also planned at North Carolina State University Minerals Research Laboratory (MRL). The primary purpose of the pilot plants is to make mineral product samples for distribution to prospective customers as part of the Company's continuing marketing efforts. In particular, several life science companies have successfully tested their products on the bench scale and now require greater volumes of halloysite as the product development progresses through the larger volume pilot plant stage.

GMT is in the final stages of completing a clay pilot plant where they produced over 2000 lbs. of ULTRA HalloPure halloysite and approximately 4500 lbs. of kaolin for use as feedstock for production of metakaolin. The sand fraction from the ore has been recently shipped MRL and is being readied as feedstock for K-feldspar and quartz pilot plant work.

The MRL recently completed a K-feldspar pilot plant where approximately 500 lbs. of K-feldspar were produced and sent to our warehouse in Coeur d'Alene. The quality of the product was consistently exceptional -- K2O >14%, Fe2O3 <0.06%, and the Al2O3 >18%, representing some of the highest K2O feldspar available.

A testing program at FLSmidth (Bethlehem, PA facilities) is scheduled for early July wherein I-Minerals will test the use of flash calcination technology. This program is being pursued as a possible conventional calcination processing replacement for potential improvement of the final metakaolin physical and reactivity properties. Flash calcination allows a smaller footprint within the process facility and could offer modest capital costs savings as a smaller mill building may be required.

I-Minerals has also engaged FLSmidth Krebs (Tucson, AZ) to undertake a testing program in July to investigate a process schematic change at the front end of the plant circuit. In this test program, hydrocyclone technology will be used to separate the clay and sand fractions at an approximate 325 mesh cut point from a sample of about 1200 lbs. of the raw primary clay. The current process schematic uses a two-stage screw classification and screening circuit to achieve the separation. If the hydrocyclone technology proves successful, the revised circuit will reduce capital costs and further reduce the building "footprint".

"The demand for our halloysite products is really gaining momentum," stated Thomas Conway, President and CEO of I-Minerals. "As additional life science applications move through the commercialization process, it appears demand for our HalloPure product is going to exceed our pilot plant inventory. This is very exciting for I-Minerals as HalloPure is by far our highest value mineral product."
