About i-minerals inc.

i-minerals holds ten minerals leases in northwestern Idaho that hosts Kelly's Basin feldspar-quartz deposit that is the subject of an ongoing feasibility study. A pre-feasibility study completed by SRK Consulting (USA) Inc. of Denver Co ("SRK"), calculated a NPV of $61 million and an IRR of 19%. Preliminary exploration work on occurrences of primary clay deposits has identified variable concentrations of kaolinite, halloysite, quartz and feldspar. The Company commissioned SRK to complete and initial assessment of the primary clay deposits through a Preliminary Economic Assessment (the "PEA") which is based upon limited, widely spaced drilling over large areas. While additional assessment work is required to fully assess the economic viability of the deposits, the PEA yielded a NPV of $95 million and an IRR of 48% and indicated these primary clay deposits may represent the largest deposit of halloysite in North America. Halloysite is a unique tubular shaped alumina-silicate mineral often referred to as a halloysite nanotube which is being increasingly used in nanotechnology applications.
