Australian innovator Altech Chemicals Ltd. said yesterday it has completed all 27 air core holes of the drilling program at the Kerrigan project in Western Australia.
According to the firm, the 27 air core holes covered a total depth of 765 meters. Each hole was drilled vertically to an average depth of 28 meters. Samples of the surrounding rock were taken every meter for the entire run of the drill.
Located about a dozen miles south of Hyden, Western Australia, the Kerrigan project covers 89 square miles of high-quality kaolin. Altech says the drilling project will allow them to update the site’s mineral resource estimate and help provide the firm direction as to the next steps for the project.
Kerrigan was first found to contain high-quality kaolin in 1992, and the site was subsequently drilled by two predecessors in interest. However, the site hasn’t been explored in 25 years save for small samples taken from two test pits.
The site was last explored by Altech in 2011, when it estimated a total of 85 million metric tons of kaolin with an ISO brightness of 85.1 percent. The firm says it will use the data from samples taken in the just-completed project to update this estimate.
Altech Chemicals is based in Subiaco, Western Australia and is attempting to implement a marketable process for delivering 99.99% (4N) HPA using conventional equipment at a lower production cost than methods currently available. It plans to construct a 4,500 metric ton per annum HPA plant at Tanjung Langsat Industrial Complex, Johor, Malaysia that will use kaolin clay from a company-owned mine in Meckering, Western Australia. The firm is fast-tracking HPA production due to an agreement with Mitsubishi for 100% of its proposed HPA production for ten years. At present, Altech intends to commence project development later this year.
