Maiden ore reserve estimated at Altech¡¯s Meckering Kaolin Deposit

Altech Chemicals Limited has announced the estimation of a maiden Ore Reserve based on the production of high purity alumina (HPA) using feedstock from its 100 per cent-owned Meckering Kaolin Deposit (M70/1334), Western Australia (Meckering). The Ore Reserve was derived from Mineral Resources estimation at Meckering, which was delineated for the purpose of HPA production.

A maiden Ore Reserve is estimated at 1.2 million tonnes @ 30 per cent Al2O3 (alumina) in the minus 300 micron (µm) kaolin fraction with a cut-off grade of 25 per cent Al2O3. The Ore Reserve at Meckering is more than sufficient to support the proposed HPA processing operation (ore delivery rate of 41,000tpa) for the initial stage 1 mine-life of 30 years.

A Mineral Resource estimated 12.7 million tonnes @ 29.5 per cent Al2O3 (alumina) in the minus 300 micron (µm) kaolin fraction with a cut-off grade of 25 per cent Al2O3. The Mineral Resources estimation at Meckering is potentially sufficient to support its proposed HPA production for over 250 years.

The Mineral Resources estimate is inclusive of the above Ore Reserve estimate and based on data from the company’s April 2016 drilling program and subsequent test work results.

Altech managing director Mr Iggy Tan commented, “The Company is pleased to present both the maiden Ore Reserve and Mineral Resources estimation. The Ore Reserve statement is a significant milestone that confirms an initial stage 1 30 year mine-life at Meckering, providing over 1.2Mt of high-quality, alumina-rich kaolin feedstock to supply the proposed HPA plant.”

“The Mineral Resource estimate is sufficient to supply the proposed HPA operation for over 250 years which will also allow further capacity expansions in the future. The next step of the process to bring Meckering into production is the submission of the mining proposal and mine closure plan as part of the approvals required for the commencement of construction in early 2017”, he concluded."
