  • Mining the Territory, September 2013 2 This presentation should not be considered as investment advice. Any party to whom this information is made available must make their own investment decisions. Any forward-looking statements included in this document involve subjective judgment, and are subject to uncertainties, risks and contingencies, which may be beyond the control or knowledge of Crossland. Future events may vary materially from the forward-looking statements and the assumptions on which the forward-looking statements are based. 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 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 Working towards production in 2016  Charley Creek REE Project situated in NT  Located 1hr from Alice Springs  Drilling has tested 1% of exploration potential  Very low risk simple mineral sands process  High proportion of Heavy and Critical Rare Earths  Excellent infrastructure  Favourable regulatory regime Mining the Territory, September 2013
  • 4  The Cattle Creek/ Western Dam alluvial fan (350km2) shown by rough outline  The REE bearing minerals are separate mineral grains of monazite & xenotime contained in alluvium  The alluvium is 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, September 2013

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.
