i-minerals inc. (CVE:IMA) reported drilling of Bovill Kaolin deposits have began with the objective of upgrading portions of the inferred resource to an indicated resource.
The press release is quoted as saying:
As noted in the December 1, 2010, press release, previous drilling had resulted in an inferred resource contained of 38.4 million tons of primary clay in four areas: WBL, Middle Ridge, Kelly’s Hump and Scablands. The current drill program will focus on drilling the WBL and Middle Ridge areas at 200-foot centers such that the primary clay contained in these deposits may be upgraded to an indicated resource. SRK Engineering (USA) inc. has provided collar locations for the 66 drill holes (21 holes at WBL and 45 holes at Middle Ridge) required to upgrade both deposits. The PEA contemplated the primary clays would be mined at a rate of about 900 ton per day. This mining rate, if applied to the inferred resource of 8.9 million tons as estimated by SRK for the WBL and the Middle Ridge areas only, would support a minimum of 28 years of mining activity.
i-minerals’ President and CEO, Thomas Conway said:
“Now that we have defined a process to accurately estimate our halloysite vs. kaolinite content in a comparatively timely fashion we can confidently advance the primary clay deposits that comprise our Bovill Kaolin Project.” “Work completed to date at Ginn Mineral Research and Durtec indicates we have a premium quality halloysite with a better aspect ratio (ratio of length to diameter of the tube) and lower levels of trace elements when compared to halloysite deposits from around the world, and at the end of the resource calculation we will have a strong estimate of how many tons of this premium halloysite product are contained within the WBL and Middle Ridge portions of the Bovill Kaolin Project.”
