JORC Statement. The information in this presentation that relates to Exploration Targets, Exploration Results, or Mineral Resources is based on information compiled by Geoffrey S Eupene FAusIMM CP, a Competent Person who is a Fellow of the Australasian Institute of Mining and Metallurgy. He is a director of the Company and a full time employee of Eupene Exploration Enterprises Pty Ltd, which is engaged by the Company. He has sufficient experience which is relevant to the styles of mineralisation and types of deposits under consideration, and to the activity which is being undertaken to qualify as a Competent Person as defined in the 2012 edition of the ‘Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves’ (the JORC Code). Geoffrey S Eupene has consented to the inclusion in the report of the matters based on his information in the form and context in which it appears. ASX Listing Rules Statement re Production Targets. This presentation is based upon a production target and forecast financial information derived therefrom that was initially reported in CUX ASX Release of 15th April 2013: “Charley Creek Rare Earth Project Scoping Study Results”. The assumptions underpinning the production targets therein continue to apply and have not materially changed. Some of the production target is based upon an exploration target. The potential quantity and grade of a exploration target is conceptual in nature, there has been insufficient exploration to determine a mineral resource and there is no certainty that further exploration work will result in the determination of mineral resources or that the production target itself will be realised.
  3. 3. 3 Working towards production in 2016  Located in Central Australia  1hr from Alice Springs  Total project area is 7,000km2  Drilling has tested just 1% of exploration potential: sufficient resource for long term production  Low risk simple mineral sands process  High proportion of Heavy and Critical Rare Earths  Good infrastructure  Favourable regulatory regime  Project on care and maintenance since early 2014, sourcing new finance arrangements; expecting project rejuvenation shortly.

  5. 5. 5 Mining the Territory August 2014 Multiple REE-bearing Alluvial Fans - Decades of Supply?
  6. 6. 6  The Cattle Creek/ Western Dam alluvial fan (350km2) shown is roughly outlined at left  The REE bearing minerals are separate mineral grains of monazite & xenotime contained in alluvial sands derived from the breakdown of basement rocks  The alluvium can be readily mined and upgraded using conventional mineral sands technology.  Average thickness of resource is 15m, commencing from surface (no overburden) with some of the alluvial fans having thicknesses up to 80m  Vast alluvial flats are inexpensive & easy to rehabilitate Mining the Territory, August 2014
  7. 7. 7  Specialized in testwork and flowsheet development for mineral sands project  Scoping study Lead, experts in mineral sand project engineering  Environmental baseline studies Mining the Territory, August 2014
  8. 8. Scoping Study is based around the concept of:  dry mining 12Mt/ year of alluvium averaging 500ppm TREO* for 5 years, followed by a throughput increase to 20Mt/year for 15 years at the demonstrated average deposit grade of 300ppm.  ROM is upgraded through primary wet plant at mine site by removing ~91% of ROM;  Upgraded Heavy Mineral Concentrate (HMC) is pumped to Secondary Wet Plant for further upgrading,  HMC is fed to dry plant at the same site; Ilmenite and Zircon plus other heavy minerals separated and stockpiled for sale;  Resulting product is REE concentrate of Monazite and Xenotime containing ~40% TREO, including around ~18% Heavy REO, mostly in Xenotime.  The REE concentrate would be further processed, through an on- site refinery to produce a saleable high grade mixed REE Carbonate product. The Scoping Study made no provision for revenue from by products (e.g. zircon) produced. Mining the Territory, August 2014 8 *This is an Exploration Target. This target is conceptual in nature, and there has been insufficient exploration to estimate a Mineral Resource of this grade, and it is uncertain if further exploration will result in the estimation of a Mineral Resource of this grade.

This target is conceptual in nature, and there has been insufficient exploration to estimate a Mineral Resource, and it is uncertain if further exploration will result in the estimation of a Mineral Resource.

  11. 11. 11  Charley Creek is a high tonnage ‘mineral sands’ style operation.  Total C1 cash costs is $7.12/t ROM or $21.16/kg REO production. Operating costs need to be reduced to get the project into the lowest cost quartile.  Several areas to reduce costs have been identified:  Costs of mining must be reduced- small improvements make big differences.  Higher grade starter pits areas to be sought in next phase of exploration.  Several process improvements expected to increase overall metallurgical recovery and lower costs.  Potential refinery reagents savings through process improvements.  Additionally, revenue may be enhanced by considering sale of by- products.
