3 Overview The Peninsula Project is located approximately 300 kilometres from Kalgoorlie. Exploration activity in this part of the Fraser Range Belt has been restricted by its remote nature as well as the presence of sand cover. Despite the location the nickel potential of the belt has been well established due to analogies with other Proterozoic mobile belts eg Canada where these belts host the Thompson, Raglan & Voisey s Bay Deposits. Companies to explore in the belt include Anglo, CRA/Rio Tinto, Geographe Resources, Teck, Newmont, Dominion, Western Areas, Placer Dome and Mark Creasy. The majority of exploration activity is best described as first pass and little follow up work was undertaken on targets which were generated, despite the companies involved. All this changed with the Nova Discovery by Sirius Resources.. 3

4 Lessons From Nova - Bollinger Diagram above is taken from Sirius Resources ASX Announcement 6 th March 2013 and shows the geological setting of the Nova and Bollinger Deposits Both deposits are magmatic sulphide deposits hosted by a mafic intrusive complex, with associated brecciation and bounded by a pyroxene-garnet gneiss. The Nova Discovery was in fact made by following up a target defined by surface geochemical sampling, airborne magnetics and EM, regolith anomalies in aircore drilling and ground EM. 4

5 Peninsula the closest Nova analogy yet? Plan of The Eye magnetic anomaly (host of Nova/Bollinger Deposit) at the same scale as Peninsula figure. See Appendix for details. A B The Peninsula Project contains one of only a few Proterozoic mafic / ultramafic intrusions identified within the Fraser Range Province. Lithologies intersected in RC drilling at Peninsula by Western Areas include mafic granulite and gabbronorite. Anomalous Ni Cu Co - S assays were returned but no deeper test of the intrusive body was carried out. In fact a significant amount of the intrusion remains untested, along with the surrounding area. 5

7 Geophysics Bouguer Gravity Image Aeromagnetics - Analytical Signal Orion acquired high resolution aeromagnetic and radiometric data from a previous survey across the project. This has now been reprocessed to show increased detail of the intrusion. Ground gravity data is also available and shows a distinct high within the intrusion. No EM surveys (airborne or ground) were previously carried out at the Peninsula Project. Orion has recently completed an airborne HELITEM survey across the entire project area. 7

8 HeliTEM Results Two significant EM anomalies associated with magnetic anomalies have been identified in the HeliTEM survey. HeliTEM Response Ch29B Insets show aeromagnetic images of PEN_HA1 & PEN_HA2 Pen_HA1 & PEN_HA2 shown on plan to right Significantly PEN_HA2 is in the same location as anomalous Ni Cu Co S intersections in historical drilling and has a coincident aeromagnetic anomaly. PEN_HA1 has not been covered by surface sampling and has not been drill tested. Drilling to east intersected low level Au-PGE. Two secondary anomalies (yellow) and three single line anomalies (stars) also identified. Interpreted Peninsula Intrusion Ground EM is planned to be carried out over all anomalies to better define conductors at lower frequencies. Conductive Overburden 8

11 Forward Work Programme Ground EM over EM anomalies to commence by end July Ground EM will more accurately define conductive bodies and assist in drill design Surface geochemical surveys are being considered to refine target definition, especially at PEN_HA1. Aim is to define robust targets for drilling later in

The Mineral Resources have been classified into Measured, Indicated and Inferred categories in accordance with JORC guidelines based variably on the assessment of geological continuity, grade continuity, drill data density and grade estimation error. Competent Persons: The information relating to the Mineral Resource is based on and accurately reflects grade estimation and modelling undertaken by Mr P. Ball B Sc MAusIMM for Orion Gold NL in his capacity as Consultant Geologist to Orion Gold. The Mineral Resource information has undergone APPENDIX review by external consultants. 1 The reported resources are in the process of remodelling and re-estimation as a result of new information and interpretations and changed economics. Mr Ball has sufficient experience in relation to the style of mineralisation under consideration to qualify as a Competent Person as defined in the 2004 edition of the Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves. Mr Ball consents to the inclusion of the mineral resource information in the form and context in which it appears. The information relating to the Cohens Mineral Resource is based on and accurately reflects grade estimation and modelling undertaken again by Mr Ball and is compliant with the 1999 edition of the Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves. 12

13 A Sense of Scale The figure used in Slides 5 & 6 is taken from the Sirius Resources ASX Announcement of 6th March 2013 which shows The Eye magnetic anomaly and the Nova / Bollinger Deposits. The image has been scaled for comparison using the scale bar in the legend of the diagram. 13

14 Orion Gold Competent Persons Statement The information in this report that relates to Exploration Results is based on information compiled by Mr Bill Oliver, a Competent Person who is a Member of The Australasian Institute of Mining and Metallurgy and the Australian Institute of Geoscientists. Mr Oliver is the Chief Operating Officer of Orion Gold NL and has sufficient experience that is relevant to the style of mineralisation and type of deposit under consideration and to the activity being undertaken to qualify as a Competent Person as defined in the 2004 Edition of the Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves ( JORC Code ). Mr Oliver consents to the inclusion in this announcement of the matters based on his information in the form and context in which it appears. 14
