i-minerals Completes Infill Drilling of Halloysite-Kaolinite

VANCOUVER, BRITISH COLUMBIA, Aug. 31, 2010 - i-minerals inc. has completed a 10 hole drilling program, totaling approximately 1200 feet, in the primary clay deposits that include the WBL Pit area. All holes intersected primary clay with thicknesses as much as 124 feet. The purpose of the program was to build upon prior results where primary clay was intersected over a very large area by tightening up the drilling in the most prospective areas such that the first resource calculation can be undertaken.
Half of the holes completed as part of the 2010 program were in the immediate vicinity of an old pit that had been the subject of historic mining efforts, the WBL Pit area. The other five holes were drilled in an adjacent ridge, referred to as Middle Ridge. During prior mining the composition of the primary clays was not well understood as the potassium feldspar and quartz fraction was wasted and no effort was made to differentiate the kaolinite and the halloysite. As noted in the Company's press release of August 4, 2010, i-minerals has made significant progress in separating and recovering these minerals.
The five holes completed in the WBL Pit area were generally about 200 feet apart resulting in an area of about 30 acres being tested by the 2010 and prior drill programs in this area. The average thickness of primary clay encountered was 52 feet with the thickest intercept being 73 feet. In the five holes drilled on Middle Ridge, the average thickness was 72 feet with a maximum intercept of 124 feet, over a prospective area of about 63 acres. The narrowest intercept was only eight feet when one hole encountered a narrow zone of primary clay prior to entering a vertical basaltic dyke where it remained for the balance of the hole.
Whole rock geochemistry results have been received and are viewed as very encouraging, but results from clay separations to determine kaolinite versus halloysite concentrations are ongoing. Once the complete clay characterization results have been received i-minerals will undertake a resource calculation that will shortly thereafter be folded into a Preliminary Economic Analysis (PEA) to assess the potential of one or two of several primary clay deposits located on the property.
"The 2010 and prior drilling programs have done much to prove our geological model of the areas of primary clay deposits," stated Lamar Long, Exploration Manager of i-minerals inc. "This drilling has identified significant volumes of primary clay, while our metallurgical work has demonstrated we can separate and recover the various minerals. We will incorporate this work into a PEA to assess the economic viability of the deposits as we believe the primary clay deposits on our Helmer-Bovill property have the potential to develop into one of the largest domestic sources of halloysite with significant co-product value from the kaolin, quartz and k-spar."
