VANCOUVER, Nov. 8, 2011 /CNW/ - i-minerals inc. (TSX.V: IMA) (Pink Sheets: IMAHF) (the "Company") has been advised by Mineral Research Laboratory at North Carolina State
University that the pilot plant commissioned to manufacture quartz
products is in operation. The objective of this pilot plant work is to
make quartz products of different purities for testing in a variety of
quartz consuming markets.
Over the past six years MRL has completed several phases of flotation-
based metallurgical work on material from Kelly's Basin, WBL Tailings
and the sand fraction from the WBL Area of the Bovill Kaolin primary
clay deposits successfully creating feldspar products through floating
the feldspar and sinking the quartz. The current pilot plant will take
the quartz "sunk" during prior metallurgical work and regrind and float
it to create higher value quartz products. As noted in the Company's
press releases of July 28, 2011 and earlier, i-minerals can create a
high purity quartz product (>99.95% SiO2) through multistage flotation.
Approximately 8000 lbs of raw quartz product from prior metallurgical
work will be processed. This material will be ground to less than 50
mesh and processed through flotation. It is expected that a minimum of
1000 lbs of Quartz 1 product (1 float lower purity); 1500 lbs of Quartz
2 product (2 float medium high purity); and 300 lbs of Quartz 3 product
(3 float high purity) will be produced. Earlier metallurgical work has
returned the following results:
BK Quartz B - 30 mesh
BK Quartz 1 - 50 mesh
BK Quartz 2 - 50 mesh
BK Quartz 3 - 50 mesh
The Company's marketing efforts have generated demand for quartz samples
for testing and having samples of the various products readily
available is beneficial to the marketing process. In particular,
several customers both in North America and Asia have requested Quartz
2 and Quartz 3 samples for melt tests to see how the products react
when heated to the liquid form. These samples can be quite large - as
much as 50 lbs each. Satisfactory completion of the melt tests would
indicate i-minerals quartz products could be used in high value
applications and markets and have a positive impact on future revenue
streams and therefore project economics.
Assuming the pilot plant runs smoothly it should take approximately 2
weeks to process the quartz stock piles. Subsequent fine grinding of
some of the quartz products will also be performed to accommodate
certain customer requirements. Samples would be sent to customers
shortly thereafter, with melt test results made available to the
Company in Q1 2012

About i-minerals inc.
i-minerals' Helmer Bovill property, located in northwestern Idaho that
hosts multiple high value industrial mineral deposits including high
purity quartz (>99.95% SiO2) that can be produced through a standard flotation process, halloysite
that has an industry leading combination of aspect ratio and lowest
levels of trace elements and potassium feldspar that has some of the
highest alkalis of k-spar products currently available. Halloysite is
a unique tubular shaped alumina-silicate mineral often referred to as a
halloysite nanotube which is being increasingly used in nanotechnology
applications. Economic assessments of both the Kelly's Basin
feldspar-quartz deposit and the Bovill Kaolin Deposits are ongoing.
While additional assessment work is required to fully assess the
economic viability of the Bovill Kaolin Deposits, a January 2011
Preliminary Economic Assessment (the "PEA") based upon limited, widely
spaced drilling over large areas demonstrated robust economic metrics
and indicated the Bovill Kaolin Deposits may represent the largest
deposit of halloysite in North America.
