Competent Persons Statement The information in this presentation that relates to Exploration Results is based on information compiled by Mr Nicholas Mather B.Sc (Hons) Geol., who isa Member of The Australian Institute of Mining and Metallurgy. Mr Mather is employed by Samuel Capital Pty Ltd, which provides certain consultancy services including the provision of Mr Mather as a Director of Aus Tin Mining. Mr Mather has more than five years experience which is relevant to the style of mineralisation and type of deposit being reported and to the activity, which he is undertaking to qualify as a Competent Person as defined in the 2012 Edition of the Australasian Code for Reporting of Exploration Results, Minerals Resources and Ore Reserves (the JORC Code). This public report is issued with the prior written consent of the Competent Person(s) as to the form and context in which it appears. The information in this Announcement that relates to Mineral Resources is based on information extracted from the report entitled Maiden JORC Resource Estimated for the Taronga Tin Project created on 26 th August 2013 and is available to view on Aus Tin Mining confirms that the form and context in which the Competent Person s findings are presented have not been materially modified from the original market announcement. In the information in this Announcement that relates to Ore Reserves is based on information extracted from the report entitled Taronga Tin Project 2014 Pre- Feasibility Study Mining Report GHD report # dated 7th April The Ore Reserve has been calculated by Mr Hugh Thompson of GHD who has sufficient experience that is relevant to the style of mineralization and type of deposit under consideration and to the activity 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. 2.

5 Maiden Ore Reserves (JORC 2012) / Mining Probable Ore Reserve estimated by GHD 0.16%Sn for 35,600t contained tin Open cut mining at Northern and Southern Zones Contractor mining Low strip ratio (Years x; LOM 1.35x) Production Target of for 36,987t contained tin 1 Competitive benefits Concurrent mining of two pits optimise equipment utilisation and present a blended feed to the processing plant Contractor mining reduces CAPEX Low strip ratio reduces OPEX Potential to expand pit subject to economics Only one of three tin companies to have reported Ore Reserves under new JORC 2012 requirements 2 Site layout as developed by GHD 1 Approximately 4.0 percent of contained tin in the Production Target is sourced from Inferred Resources. This material has been included on the basis that it falls within the proposed pit shells and the nature of mineralisation is consistent throughout the orebody. However, there is a low level of geological confidence associated with inferred mineral resource and there is no certainty that future exploration work will result in the determination of indicated mineral resources or that the production target itself will be reaslised. It could be reasonably expected that in an optimised production schedule the exclusion of inferred material would have minimal impact on the project economics 2 Metals X (11March 2014) and Kasbah Resources (31 March 2014) 5.

6 Metallurgy / Processing Plant Metallurgical Review conducted by Ron Goodman Predominant tin mineral cassiterite is coarse grained and simple metallurgy compared to other projects Ore highly amenable to pre-concentration Overall tin recovery 70% 2.5Mtpa Processing Plant designed by DRA Pacific Three stage crushing and Heavy Medium Concentration Coarse primary grind and gravity tin recovery Secondary grinding and sulphide flotation Filtration and bagging of 55% Sn grade concentrate Competitive Benefits Heavy medium rejects 60% of waste prior to grinding Coarse grind reduces losses of fine tin Medium grade concentrate with little deleterious elements Areas of Identified Upside Increased tin recovery through advances in gravity technology and tin flotation ti Inclusion of by-product credits, notably copper and silver Processing plant layout as designed by DRA Pacific 6.

9 Future Work Program Secure funding for the Definitive Feasibility Study (DFS) and the proceed with the program (noting funding discussions have been on-going with a range of groups globally) Target completion of Definitive Feasibility Study by March

10 Areas of potential upside could significantly enhance economics Areas of potential revenue upside to be evaluated in conjunction with Definitive Feasibility Study, for example Increased plant feed grade (increasing sample volumes yield increased grades) target from 0.16%SN to 0.19%Sn Increased tin recovery (improved recovery of tin by gravity and flotation) target +2% to 72% Recovery of copper & silver as by-product credits (encouraging results reported 20 May 2013) target 30% recovery Areas of cost saving to be evaluate in conjunction with Definitive Feasibility Study Reduced mining OPEX (evaluation of smaller equipment in haul/dump) Targeted revenue increase of 30% during DFS 10.

11 Evaluating areas of potential upside - Exploration Regional exploration for extension of mine life Field has produced in excess of 88,000t of tin in concentrate Oer Over 500 known n occurrences of tin in the region Advanced exploration targets at McDonalds, Pound Flat and Emerald, all within trucking distance Target high grade supplementary feed to increase plant feed grade McDonalds (historic mining & primary target) Planet (high Sn grade intercepts) Central Plant at Taronga Dutchman & Harts (historic Sn mine) Pound Flat (historic Sn resource) Emerald (historic mine & primary target) 11.
