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……..

Lessons From Nova - Bollinger

• Diagram above is taken from Sirius Resources ASX Announcement 6th 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.

Peninsula – the closest Nova analogy yet?

• 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.

Geophysics

• 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.

HeliTEM Results

• Two significant EM anomalies associated with magnetic

anomalies have been identified in the HeliTEM survey.

• 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.

• Ground EM is planned to be carried out over all anomalies

to better define conductors at lower frequencies.

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 2013.

Notes:

• Tonnes are rounded to the nearest 000, grade is rounded to the nearest 0.1, the ounces Au rounded to the nearest 100
• The cut-off grades for Tubal Cain and Eureka are set at values required to report only that part of the total in situ Mineral Resource which it is believed has potential to be mined economically by

underground methods suitable for narrow vein deposits

• The cut-off grade for the Cohen’s Deposit (previously referred to as the Cohen’s Stockwork Deposit) is set so as to report only that part of the Mineral Resource which it is believed has potential to be

mined economically by underground bulk mining methods

• These Mineral Resources are exclusive of areas of these deposits which are known to have been previously mined.

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 review by external consultants. 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”.
