Exploration Update:

Walhalla Polymetals Project

Orion Gold NL (ASX: ORN) is pleased to present the attached Exploration

Update with regards to exploration activities at the Walhalla Cu-Ni-PGE

Project (the “Walhalla Polymetals Project”).

The presentation contains new exploration results from surface sampling, an

Exploration Target for the Coopers Creek Prospect as well as giving investors

further information about the geological model for the polymetallic

mineralisation.

The presentation also highlights the unique opportunity that the Company

believes exists at the Walhalla Polymetals Project, namely to delineate a

resource and develop a PGE-bearing deposit in a very supportive, first world

location.

The information in the presentation should be read in conjunction with the

Disclaimers on slide 2 and the Competent Persons Statements on slide 21.

Walhalla Polymetal - exploration rationale• Walhalla – Woods Point district is famous as the 3rd largest goldfield in Victoria, but…high grade copper –

nickel - PGE also known to occur within the district

• Both mineralisation styles are related to the Woods Point Dyke Swarm (‘WPDS’)• ~75 km long belt of ultramafic to felsic dykes

• The ‘plumbing’ for a larger, now eroded, package of igneous rocks?

• Dykes of the WPDS and +1Moz Au deposits (i.e. Cohens, Morning Star, A1) share an intimate spatial association

• Recent studies support co-genetic model for Au and polymetallic mineralisation – Au leached from earlier formed magmatic sulphides

• The key “known” Cu-Ni-PGE occurrences in the district (see Slide 7) relate to magmatic sulphides within dykes (bulges) which display a significant ‘primitive’ (i.e. mantle-derived) component:

• Coopers Creek

• East Walhalla

• Maynard’s Gully

• Shamrock

• New Loch Fyne

• The polymetal (Cu-Ni-PGE) potential of the WPDS has been largely ignored• Several known Cu-Ni-PGE occurrences, including small-scale mines (Coopers Creek)• Sporadic exploration in the 1970’s – 1980’s (majority focused on Coopers Creek)

• Project being re-assessed as a result of new developments in the understanding of controls on magmatic sulphide mineralisation

6

Host morphology - polymetallic deposits• Geometry of the host intrusion is just as

important as its petrology

• ‘Trap sites’ are crucial in order to facilitate accumulation of the magmatic sulphides

• Gravity accumulation – settling of sulphides & early-formed silicates from magma

• Changes in magma flow-rate – dilation point or bend/choke point in intrusion

• Low to moderate angle basal contacts to intrusions

• Plunging dyke bulges (plunging base ≤60o)

• Sills/Lopoliths (sub-horizontal intrusions)

• Intrusions into low-angle reverse faults

• Intrusion into anticlinal folds

• Geophysics crucial in order to map sub-surface geometry of prospective intrusions Note small surface expression of high grade

mineralisation

Understanding The Opportunity

• Small, poorly understood surface expressions probably reduced historical interest

• Modern geological understanding emphasises the opportunity present in deposits of this style:

• In general the host intrusives have low but anomalous metal tenor at surface

• Only a small area within the intrusive contains significant concentrations of metals (at levels which are economically significant)

• These zones are likely to be relatively high grade and continuous down plunge (Coopers Creek deposit drilled to 300m below surface)

• The small footprint area of the deposit, facilitates access for exploration with small surface area disturbances - reduced exploration costs and environmental impact

Notional exploration targetSchematic Plan Section – Notional Exploration Target

Schematic Long Section – Notional Exploration Target

• 25m (strike) x 125m (average width)• Intersected in drilling 300 metres below surface• SG: 3.2 t/m3

• Tonnes: 10,000t / vertical m• Au equivalent grade: 5 – 6 g/t (based on CC003)

• Cu equivalent grade: 3 - 4% Cu (based on CC003)

Therefore based on a vertical extent of between 200 and 400 metres the Exploration Target for the dyke keel is2 – 4 million tonnes of copper – nickel – gold – PGE mineralisation at a grade between 5 – 6 g/t Au equivalent or 3 – 4 % Cu equivalent.

• Exploration target is approximately 1,600oz Au / 300ton contained Cu equivalent per vertical m

• Over a 600m plunge extent this could represent a ca. 1Moz Au equivalent / 180,000 ton contained Cu equivalent

Please refer to the Competent Persons Statement on slide 21. The information on this slide relating to Exploration Targets is consistent with the 2004 JORC Code and should not be misunderstood or misconstrued as an estimate of Mineral Resources or Ore Reserves.

Coopers Creek• Mined sporadically for Cu, records of Ni, Pt,

Pd, Au, Ag content from 1865 to 1913• Total material mined: ca. 13,200t

• Two styles of sulphide mineralisation evident• Accumulation of polymetal sulphides within

interpreted ‘keel’ of north-plunging dyke bulge;• Sulphide injection within a dyke-parallel fault

• Historic 1980’s exploration drilling directly tested the ‘keel’ model, intersecting 36m @ 1.75% Cu, 0.2% Ni, 0.78g/t Pt, 1.08g/t Pd, 0.39g/t Au, 8.6g/t Ag

• including 3.5m @ 3.23% Cu, 0.53% Ni, 1.16g/t Pt, 1.64g/t Pd, 1.3g/t Au, 14.4g/t Ag

• This mineralisation remains open down plunge to the north

• Dyke bulge expanding at depth

• Remnant drill core available at GSV core library for logging, geochemical and petrological analysis – crucial to development of both prospect-scale and district-scale exploration models

• No recorded production

• Mineralisation evident as copper carbonate staining (after primary copper sulphides)

• Soil sampling (1970’s) highlighted a Cu+Ni in soils anomaly1

• One drill hole (1970’s – location unknown) reportedly returned 0.6m @ 0.35% Cu, 1.5g/t Pd, 0.5g/t Pt, 450ppm Ni1 (selective sample only – “minor sulphides” noted throughout the drilled dyke interval)

• Grab samples by Orion (May 2013) return up to 0.2% Cu, 374ppm Ni, 520ppb Pd, 315ppb Pt

• Similar results to poorly mineralized portion of Coopers Creek dyke (i.e. hole CC002)

• Poorly explored analogue to Coopers Creek?

Notes:• Orion has considered the in-situ grades reported in the context of the current metal prices as reported by Kitco.com and the London Metal Exchange

on 3 July 2013.• The gangue and ore mineral assemblage as reported for the intersection is typical of PGE ores commonly mined in Southern Africa where >90% of world

PGE production takes place. The metals and minerals identified are conventionally recoverable to a sulphide concentrate with standard metallurgicalpractices and a reasonable expectation of recovering >90% of each of the ore minerals. The concentrates produced can be expected to havecomposition typical of those commonly purchases and/or toll treated by base metal + PGE refineries in South Africa. The Competent Person is thus of theopinion that the metal equivalent estimate is a reasonable approach as an initial indication of economic merit of the mineral occurrence. The metalequivalence is stated as gold equivalence for Orion, which is a gold exploration and development company and has reported JORC compliant goldresources on the same tenement. Copper equivalence is also states since copper is the metal contributing most economic value in the intersection.

Orion GoldCompetent Persons Statement

• The information relating to the Tubal Cain and Eureka Mineral Resource is based on and accurately reflects grade estimation and modelling undertaken by Mr P Ball BSc MAusIMM for Orion Gold NL in the capacity as Consultant Geologist to Orion Gold. The Mineral Resource information has undergone review by external consultants. 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 “AustralasianCode for Reporting of Exploration Results, Mineral Resources and Ore Reserves”.

• 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”.

• Exploration Results, Exploration Targets and other technical information in this report has been compiled and assessed under thesupervision of Mr Errol Smart, Orion Gold NL’s Managing Director, from historical records and field investigation. Mr Smart (PrSciNat) is registered with the South African Council for Natural Scientific Professionals, a ROPO for JORC purposes and has experience in the identification and exploration of mineralisation of this style. Mr Smart consents to the public release of the information in the context contained within this release 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 Smart consents to the inclusion in this announcement of the matters based on his information in the form and context in which it appears.

• It is common practice for a company to comment on and discuss its exploration in terms of target size and type. The information in this announcement relating to Exploration Targets should not be misunderstood or misconstrued as an estimate of Mineral Resources or Ore Reserves. Hence the terms Resource(s) and Reserve(s) have not been used in this context in this announcement. The potential quantities presented in this announcement as Exploration Targets are conceptual in nature. It should be noted that there has been insufficient exploration to define a Mineral Resource which complies with the JORC code, andit is uncertain if further exploration will result in the determination of a Mineral Resource. Orion Gold NL intends to carry out an exploration programme to systematically test the Exploration Target for each of the Prospects.
