SMEDG is a not-for-profit organisation affiliated with the Australian Institute of Geoscientists. Mr Levy will present his views on geology and processing of ionic adsorption clay rare earth resources, such as the ABx Deep Leads resource in northern Tasmania, with some personal comments on the future of Australian rare earths industry, based on his 50 years’ experience in the growth of and major changes in Australia’s resources industry. Mr Levy’s presentation is at 6:00pm AEST on Thursday 23 April at Club York, 99 York St, Sydney. This announcement is approved for release by Mark Cooksey, Managing Director and CEO.

Slide 18 Future of Australian clay-hosted REE deposits Lessonsfrom Australia’s175years of miningsuccess 1. Metallurgical breakthroughs are happening for mainland clay REE projects Historical examples: 1. Carbon-in-leach cyanidation for gold 2. Flotation for base metals 3. Heap leach for gold, base metals 2. Mining breakthroughs Historical examples: 1. Bulk open pits: gold, coal, iron ore & bauxite mines 2. In-situ leaching for uranium, copper 3. PRICES FOR REE – Global economic-industrial developments Historical examples: 1. Gold 1975 US$35/oz, cog 8g/t 2026 US$4,900/oz, cog 0.5g/t 2. Cu price rose when Chilean leachable copper exhausted TRENDS 1. Prices of Dy & Tb RISING STRONGLY as Southern Chinese mines deplete 2. Acid leaching of REE phosphate rhabdophane may become viable at higher prices 3. US and EU prices for good quality Dy-Tb rich MREC have been increasing Slide 19 Suite 2 Level 11, 385 Bourke St, Melbourne VIC 3000 P: +61 3 9692 7222 F: +61 2 9956 7355 E: corporate@abxgroup.com.au W: www.abxgroup.com.au Thank you
