Attendees at this presentation are cautioned not to place undue reliance on such forward-looking statements.  Crossland makes no representation or warranty as to the accuracy, reliability or completeness of information in this document and does not take responsibility for updating any information or correcting any error or omission which may become apparent after this document has been issued. JORC Statement: The review of exploration activities and results, and Mineral Resource contained in this presentation are based on information compiled by Geoffrey S Eupene FAusIMM(CP), 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. He has sufficient experience which is relevant to the style of mineralisation and types of deposits under consideration, and to the activity which he is undertaking to qualify as a Competent Person as defined in the December 2004 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 this report of the matters based on his information in the form and context in which it appears.
  • 3.  Very large tonnage with potential for many decades of REE production  Favourable mineralogy and metallurgy  Low cost mining and gravity concentration using standard heavy mineral sands techniques  High proportion of critical heavy rare earths
  • 4. Source of REE in the mountains Alluvial plains Deposit Model
  • 5.  Rare Earth Elements impact almost every aspect of modern life. A third of all metals are Rare Earths.  “[Rare earth] will do for China what oil did for Saudi Arabia.” - Deng Xiaoping  China presently produces around 97% of all REE and has tight quotas on exports  Quotas have resulted in major price rises and supply concerns, though these are now being impacted by economic slowdown.  Rest of World production scrambling to start up; strategic concerns dominate western thinking. 1 Quote from Dan Cordier, co- author of USGS 2010 Report:” “Principal Rare Earth Elements Deposits of the United States—A Summary of Domestic Deposits and a Global Perspective

  • 7. Heavy Rare earths
  • 8.  The Critical REO (Dy, Tb, Y, Nd, Eu) dominate the Charley Creek REO distribution by value  At current available FOB China prices, the value of contained REO in the CUX basket is US$84.60/Kg (August 24, 2012 Metal Pages)  Based on the Toyota Forecasts for 2016, the value of the contained REO in the CUX basket is US$47.46/Kg.  This is a conservative value which CUX has used to calculate cut-off values. Current market indications suggest it may be overly conservative.  The highest value component is Dysprosium oxide (US$15.83/Kg)  80.2% of the value of the CUX basket is in the Critical REO
  • 9. Aircore drilling completed to date has defined the following Resource  Indicated Resource - 387 million tonnes containing 114,000T of TREO  Inferred Resource – 418 million tonnes containing 121,000T of TREO This drilling has tested a very small percentage (<1%) of the alluvial outwash. There are over 2,000sq. Km of potentially mineralised alluvial outwash within CUX’s 6, of Exploration Licences at Charley Creek. Average thickness of resource is 15m, commencing from surface (no overburden); Alluvium reported to be up to 80m thick in places.
  • 10. Vast alluvial flats Cheap and easy to work and rehabilitate Almost unlimited siting options
  • 11.  Contains a broad mix of all REE, but with ~80% of value in the CRITICAL REE.  The mineralisation is in alluvial deposits which are free digging, with no overburden, so mining costs are low.  The mineralisation is readily upgradeable to high grades of contained TREO in concentrate (>40% TREO) by physical, low cost methods. So low process risk.  REO are present in two easily dissolvable phosphate minerals – Monazite (the Light REO) and Xenotime (the Heavy REO).  Scalable and flexible development options.  The Northern Territory regulatory regime is familiar with nuclear materials handling, and all permitting issues should be addressable.  One hour from Alice Springs (Railway); straddles gas pipeline (energy); good prospects for underground water.
  • 12.  REE are contained in many minerals, but only a few have been used to produce commercial REE.  The light rare earths (LREE) and medium rare earths (MREE) are found mainly in bastnäsite and monazite.  Heavy rare earths (HREE) are somewhat more scarce and typically concentrated in ionic adsorption clay found in south eastern China, Xenotime, and in complex silicate minerals.  The Phosphate Minerals, Monazite and Xenotime have long been the preferred source of REE, and these minerals have relatively predictable processing characteristics.  Crossland’s REE mix contains a good spread of REE, including significant HREE (17% by weight, and 50% by value), while the mineralogy is Monazite and Xenotime. Almost all of the HREE are in Xenotime.
  • 13. monazite xenotime zircon
  • 14.  Initially dry mining with contractors feeding mobile washing plants.  Possibly multiple extraction sites to enhance flexibility.  Evolving into dredging operation in deeper alluvium.  All alluvial tailings returned directly to excavation sites for rehabilitation, with slimes management.  Expect Wet Plant HMC recoveries of 10kg- 30kg/T of feed with HMC grades of 2-12% TREO.  Expect mineral sands type costs.
  • 15. WET plant DRY plant Refinery Mining, washing, gravity concentration On site magnetic and electrostatic processing On site(?) chemical plant to produce REO oxides/ hydroxides: Basket value: @Toyota 2016 prices: $47.46/kg; @Current Prices:$85/kg 2%-12%TREO ~40%TREO Mine gate HM concentrate with >2%up to 12% TREO at the mine gate: i.e. similar grades to most Hard rock deposits; Better REO Mix than most. Because concentrate TREO grade is high, the size of the chemical plant is correspondingly small 15-20MT/yr 150,000- 600,000T/yr 12,500- 17,500T/yr 5,000-7,000t/yr REO products Potential for short term off- take agreements to other REE producers.
  • 16. 1. Alluvial Mining- free- dig and no overburden 2. Wet Plant to produce Heavy Mineral Concentrate (HMC) 3. Dry Plant treatment of HMC to produce saleable mineral products (e.g. zircon), and/or process feed (e.g. monazite and xenotime) 4. Chemical processing of monazite and xenotime to produce value added oxide and hydroxide products 5. Production of separate refined REE metals. Crossland has no plans to produce refined metals. It will sell value added oxide and hydroxide products (Stage4) and zircon (Stage3); 6. Early development possibly facilitated by xenotime/monazite off- take deals with other producers (initial Stage 3 product).
  • 17. Process development tests now concluded at AML in Perth Spirals showing good HM recoveries with TREO grades of up to 12% Wet plant process development tests under way at AML, Perth
  • 18.  Sighter tests completed on concentrates prepared on site at Charley Creek  Process validation tests, on concentrates from wet plant testwork, now complete  Testwork on magnetic and electrostatic separation of monazite and xenotime is producing high grade concentrates (>40%TREO achieved: TARGET 50%TREO)  Target combined wet and dry plant recoveries of >70%;
  • 19.  Process development for heavy mineral concentrate production (completed September 2012)  Follow up process and marketing studies (Sept 2012 - 2013)  Leach Tests (Sept- November 2012)  Scoping study (completion late 2012)  Commence long- lead environmental baseline studies Q3 this year  Regional exploration for high Xenotime ratios and grades (Phase 1 completed June 2012)  Optimise definition of alluvial fan Resource (early 2013)  Feasibility Studies during 2013. A pathway to early permitting and production.
  • 20.  Production of saleable high grade ~40%- 50% REO mineral concentrates – 2015  Leading into staged development to production of REO products
  • 21.  Listed on ASX April 2007  Experienced, well qualified team  A lot of Northern Territory and radioactive mineral experience  Projects mostly internally generated, low acquisition costs, good prospects for capital gain  Initial uranium focus, with an evolved importance of REE  Charley Creek Alluvial REE Project under definition since late 2010  Crossland’s immediate focus is to confirm the viability of developing its alluvial REE resources in Charley Creek and getting them quickly to production
