Feasibility Work Update

VANCOUVER, BC -- (MARKET WIRE) -- June 20, 2005 -- i-minerals inc. (TSX-V: IMA) announces that it is awaiting final analytical results from the recent Phase 2 drill program prior to resuming drilling on more closely spaced drill hole centers. Drilling completed to date as part of the Phase 2 program is comprised of 21 HQ diamond drill holes located on 400-foot centers designed to up-grade the Kelly's Basin Inferred Mineral Resource. As noted in the Company's press release of February 26, 2004, the Kelly's Basin deposit contains an Inferred Mineral Resource, as defined by NI 43-101, of 5.4 million tons of feldspar and 2.2 million tons of quartz contained within an 18.1 million ton block of granitoid rock. The deposit has been restricted to an average thickness of 100 feet to keep within open pit mining parameters and has overburden cover that averages just 12 feet.

From within the inferred resource the Company will select an area with the least overburden and most favorable geochemistry to develop a resource of sufficient size to support a minimum of 15 years of mining operations. The continuation of Phase 2 drilling is the in-filling of the 400-foot spaced drill holes with the 200-foot spaced drill holes. This will result in approximately 50 additional diamond drill holes with a NQ diameter core. Completion of the drilling at this drill hole separation is sufficient to upgrade the resource to a Measured and Indicated status as part of the ongoing feasibility work process. Complete analytical results should be available in about two weeks at which time the drill program will resume.

The Company has commissioned additional quartz and feldspar metallurgical work that is underway at the Mineral Research Laboratory in North Carolina ("MRL"). This bench scale production will generate both feldspar and quartz products when this work is completed. This work will further refine the flow sheet that in turn will determine the milling equipment necessary and serve as an input to the capital cost estimation as part of the feasibility work. The production of both quartz and feldspar products will provide additional information as to both grade and recovery. The feldspar product produced as a result of the current work will be forwarded to prospective customers for their internal testing. A portion of the quartz product produced, if suitable, will be sent for additional testing to determine if high purity quartz ("HPQ") products could be produced from the Kelly's Basin deposit. HPQ products are a value-added market and offer the Company significant upside potential. Accordingly, the results of the high purity quartz testing stand to have a pronounced impact on the Company's product mix and financial models to be completed as part of the feasibility work.

"With several phases of metallurgical work already completed, we are generating increasing confidence in the production flowsheet. The ultimate validation of our feldspar product will come from our prospective customers and we are very anxious to get these samples processed and delivered," commented Roger Kauffman President and CEO of i-minerals inc. "All of our preliminary work on the quartz is very encouraging regarding the potential production of HPQ products and the potential this adds to an already attractive project is noteworthy."

In addition, i-minerals has also commissioned a leading research firm to undertake characterization work on the kaolin clays. Completion of this characterization work will determine which markets and applications the kaolin products that might be produced from the Helmer-Bovill property are best suited for and provide a preliminary valuation of these clays. Preliminary results with kaolin crude products are very encouraging. Definitive results will be released when available.

A. Lamar Long, CPG, is the Qualified Person ("QP") for the Helmer-Bovill project under NI 43-101. He oversees the quality control and quality assurance program and the construction of the bulk samples sent to MRL and reviews all analytical results prior to public release.
