I-Minerals Ultra Hallopure Halloysite used in HEAL CARE Wound Bandages

Vancouver, British Columbia--(Newsfile Corp. - April 24, 2018) - I-Minerals lnc. (TSXV: IMA) (OTCQB: IMAHF) (FSE: 61M) (the 'Company') announces its ULTRA HalloPure✍ halloysite has been used for the production of prototypes of HEAL CARE, an innovative wound bandage. See the Company's press releases of February 9, 2016 Initial results for this life science product and January 18, 2017 for earlier development updates.

HEAL CARE has now progressed to prototype production under the management of Speed Care Mineral UG (haftungbeschr.) ('Speed Care'), a company situated in Neubrandenburg, Germany. As noted in the Company's prior press releases the HEAL CARE product is a halloysite impregnated gauze that demonstrates blood clotting action comparable, or in some instances, better than other products such as Z-Medica 's Combat Gauze product. HEAL CARE was developed with the support of several contract partners working in conjunction with Speed Care. The material components and production technology for HEAL CARE are protected by patent application. Results of the effectiveness of HEAL CARE have been documented through a series of extended in-vitro and animal test programs completed under the supervision of leading medical doctors. The excellent results to date have drawn the attention of four European medical companies that have expressed interest in the future distribution of HEAL CARE. The further development concept of Speed Care was awarded by the EU within the 'Horizon 2020-Programm' with the 'Seal of Excellence'. In addition, on April 23, 2018 Speed Care Mineral was named the winner of the Health Care Competition 2018 Mecklenburg-Vorpommern county award for the concept and the high innovation potential.

'Halloysite is a truly unique mineral and for the high value life science applications such as HEAL CARE, our ULTRA Hallopure is the best halloysite product available for such applications.' stated John Theobald, President and CEO. 'We are pleased to have provided ULTRA Hallopure for the development of the innovative HEAL CARE product and as noted in our recent press release, we have started a bulk sample processing program that is forecast to make a further 3 tons of our HalloPure and ULTRA HalloPure products available for commercialization of HEAL CARE and other life science products. For applications such as life sciences, our combination of the size and geometry of the nanotube together with very low heavy metals levels and no cristobalite or alunite, our ULTRA HalloPure has no real competitors.'
