Initial Quartz Testing Yields Positive Results

VANCOUVER, BC -- (MARKET WIRE) -- November 28, 2006 --i-minerals inc. (TSX-V: IMA) has received analytical results from Acme Analytical Laboratories in Vancouver, BC on a series of quartz product samples produced by Minerals Research Laboratory at North Carolina State University ("MRL") that indicate that residual feldspar can be readily separated from the quartz by routine flotation processes to yield a quartz product in excess of 99% SiO2. The samples were created by MRL through a secondary float of the quartz tails generated during the production of the Helmer-Bovill sodium feldspar product.

Management of i-minerals is highly encouraged by these results. "These preliminary results meet our initial expectations," commented Roger Kauffman, President and CEO of i-minerals inc. "We have now confirmed that we will be able to produce quartz products that will readily compete in many glass, ceramic, and filler markets. While there remains additional important testing to complete, these preliminary results indicate we may be able to produce a HPQ product as our research indicates low elemental concentrations in the quartz mineral grains found in the granitoid rocks within the Helmer-Bovill area and similar materials have been processed to yield high purity quartz products. Accordingly we look forward to the next series of results with great anticipation."

The separation of the residual feldspar from the quartz through routine flotation is a critical threshold that needed to be achieved is assessing the potential to produce a quartz product from the Helmer-Bovill deposit. Oxides deleterious to the production of quartz products, most notably iron (Fe2O3), titanium (TiO2) potassium (K2O), sodium (Na2O), and alumina (Al2O3) were significantly reduced in this secondary flotation step. In light of these highly encouraging results, management will be commissioning further analytical testing and metallurgical work to more accurately assess the quartz product. The first set of such tests will include forwarding sample splits to a specialty laboratory prior to year-end. Here, analytical techniques will be implemented that have lower detection limits for both oxides and trace elements and that will more accurately measure silica concentrates. Results from this work should be available in the first quarter of 2007. The next round of testing will include metallurgical work to determine the viability of producing a high purity quartz ("HPQ") product.

To produce a HPQ product, total deleterious elements must be reduced to several hundred parts per million or less. As a result, simple flotation such as that utilized during the preliminary metallurgical work is only an initial step in the production of a HPQ product. More complex procedures that include additional flotation steps, leaching, and calcination are necessary to reach the required purity thresholds, which is capital intensive and require high processing costs. The scarcity of high purity quartz feed material coupled with the complex production techniques create the value of HPQ products that can range from several hundred to several thousand dollars per ton depending on the level of purity achieved.

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 all samples for metallurgical analysis and reviews all analytical results prior to public release.
