The Lost Time Injury Frequency Rate (LTIFR) per 200,000 hours worked is 0.0 for the Quarter and 0.0 for the
financial year to date.

Environmental Management

In April, approval was received for the Electromagnetic Capability plan (EMC) for the Prieska Copper-
Zinc Project (Prieska Project) from the South African Astronomy Management Authority (AMA) - the
governing body managing the Square Kilometre Array Radio Telescope Project (SKA). This EMC details
how electromagnetic emissions from electrical and electronic equipment planned for use at the Prieska
Project will be managed so as not to interfere with the efficient operation of the SKA radio telescope. This
is an important milestone to obtaining full approval from the AMA to conduct mining operations in the
region.

Community and Stakeholder Engagement

The Company facilitated the election and appointment of local community representatives onto the
Prieska Project Stakeholder Engagement Forum (SEF). Public meetings were held in the towns of Prieska,
Marydale and Niekerkshoop, where a total of ten representatives were elected. The balance of the SEF
membership will comprise representatives from Company management, employees and shareholders,
as well as representation from local government departments. The SEF will serve as a platform for
representative community interest groups to keep appraised of developments at the Prieska Project. The
inaugural meeting of the newly established SEF was held in July 2019.

In April, a community briefing session was held in Copperton to update residents and interested parties
on progress with the Prieska Project, and to provide an opportunity for the community to engage with
the Company’s management team in an informal setting.

The Company held introductory mining familiarisation short-courses during the Quarter, with participation
and successful completion by 290 high-school graduates from the Siyathemba Municipal area. The
program was aimed at raising public awareness of the mining industry and the employment opportunities
the industry creates. The training was facilitated by an accredited service provider, Mathome Training
and Development (Pty) Ltd, and participants earned credits towards industry-recognised mining-related
qualifications.

During the Quarter, the Company and the Siyathemba Municipality (Municipality) progressed formulating
the terms of collaborating on water supply infrastructure upgrades and use, with the aim of concluding
an agreement before year-end.

The Spatial Planning and Land Use Management Act (SPLUMA) application process was initiated this
Quarter, with professional land surveys being done. The SPLUMA process will result in town planning
permissions being granted to allow residential development within the Prieska town surrounds, for use for
the Prieska Project and by the public in general.

Tenement Overview

During the Quarter, the Company continued works on its highly prospective South African projects, where
a Bankable Feasibility Study (BFS) for the Prieska Project was completed and soil sampling was undertaken
at the Near-Mine prospects and regional project, Kantienpan. In the Fraser Range, the Company’s joint
venture partner, IGO, began a drill program, as follow up testing from recent geophysical surveys that
identified a number of targets.

Exploration and Mine Development

Areachap Belt Projects (South Africa)

Prieska Copper-Zinc Project

Project Overview

The Prieska Project remains the focus of the Company’s activities and is at an advanced stage, with a
maiden Ore Reserve estimate and a BFS having been recently completed on the project (refer ASX
release 26 June 2019). The Project covers un-mined dip and strike extensions from a historical underground
mining operation, where mineralisation had been delineated through extensive drilling undertaken by
previous owners. The Company has digitally captured, validated and modelled all relevant project drilling
data available from hard-copy sources, enabling the Company to define targets for both near-surface
and deep-seated mineralisation. The near-surface target comprises oxide, supergene and primary
sulphide ore to a depth of 100m which is accessible via an initial open pit mine (+105 Level Target). The
deeper target comprises primary sulphide ore accessible via underground mining (Deep Sulphide Target).

The Company’s strategy has been to validate and quantify the historically identified targets to a sufficient
level of confidence to support a BFS, using infill and verification drilling from surface, and then develop a
mining plan to exploit the resource (Foundation Phase). Thereafter, the Company intends to continue with
extensional exploration, to define the extents of the various targets.

Feasibility Studies and Mining Right Applications

Bankable Feasibility Study

The Bankable Feasibility Study was completed during the Quarter and published on 26 June (refer ASX
release 26 June 2019). The key outcomes from the BFS are listed below:
       -   Undiscounted free cash-flows of AUD1.1 billion pre-tax (AUD819M post-tax).
       -   NPV of AUD574M pre-Tax (AUD408M post-tax) at an 8% discount rate.
       -   IRR of 38% pre-Tax (33% post-tax).
       -   Peak funding requirement of AUD378M.
       -   Payback period from first production of 2.9 years.
       -   All-in-sustaining margin of 44%.
       -   All-in-sustaining unit costs of AUD5,470/t (USD3,773/t) of copper-equivalent5 metal sold.
       -   A maiden Probable Ore Reserve of 13.62Mt at 1.1% Cu and 3.2% Zn for 143kt of contained
           copper and 433kt of contained zinc6.
       -   Total planned milled production of 20.8Mt at 1.1% Cu and 3.4% Zn (comprising 65% Probable
           Ore Reserves and 35% Inferred Minerals Resources7).

The BFS investigated the commercial viability of an initial ten years of mining operation (Foundation
Phase). The Foundation Phase would result in the establishment of mine infrastructure and operational
capacity that is intended to become the platform for further mining of deposit extensions, and the
exploration and mine development of neighbouring prospects.

The Foundation Phase runs for 10 years of run-of-mine production at a design ore processing rate of
2.4Mtpa. This phase targets the exploitation of those portions of the Prieska Deposit that were upgraded
to Indicated and Inferred Mineral Resources from the first surface-based drilling campaign conducted
between 2017 and 2018. The Production Target is composed of 65% Probable Ore Reserves and 35%
Inferred Mineral Resources, with Ore Reserves predominating during the early stages of the mining plan.
The Ore Reserves and Mineral Resources underpinning the Production Target have been prepared by
Competent Persons and in accordance with the JORC Code 2012.

Table 1 summarises the assumptions used in the BFS along with the main production and financial results:

Table 1: Key BFS Results for the Foundation Phase of the Prieska Copper-Zinc Project. Note that the Study estimation accuracy level is ±
15%

Post-Feasibility Study Workstreams

With the BFS now complete, effort is now focussed on pilot-scale field trials of key activities, business plan
optimisation work, securing of long-lead time items, formalising key service and supply contracts and
developing the Company’s Prieska Project execution capacity.

Pilot-scale dewatering system trials - Pilot-scale trials have been commissioned to further test water
qualities, refine the proposed pumping system, investigate means of cost-effective water-treatment and
to confirm the size and arrangement of evaporator units to be used. Water treatment trials are being
conducted first and are due to be completed during Q3 2019. Thereafter evaporator field trials are
planned and due to be completed before year-end 2019.
    o    Water Treatment. The water treatment trials will provide engineering data to allow detailed design
         and costings for treating the accumulated water to a range of water purification specifications.
         Water treatment would allow offsite discharge and other secondary uses of water to be
         considered and so reduce the volume of water that needs to be evaporated.
    o    A 5m3 per hour, pilot water treatment plant, bespoke for the Prieska Project’s water and schedule
         requirements, has been constructed and commissioned. The plant is a combination chemical
         treatment, precipitation, ultrafiltration and reverse osmosis (RO) purification plant, configured to
         allow measurement and testing of key design parameters, (see Figures 1 and 2).

Figure 1: Water treatment plant flowsheet.

Figure 2: (LHS) Water treatment pilot plant mobilisation. (RHS) Commissioning the chemical treatment, ultrafiltration and reverse
osmosis components of the pilot water treatment plant, setup to operate at 5m3/hr of feed water.

Successful water treatment would allow offsite discharge and other secondary uses of water to be
considered and so reduce the volume of water that needs to be temporarily stored in lined environmental
control dams and force evaporated. Reducing the footprint of the lined storage reservoir and the amount
of forced evaporation required represents a major target for capital reduction. A combination of
optimising placement of plant tailings as backfilling over life of mine, and a reduced requirement for
sealed storage and evaporation area could materially reduce the capital cost of the combined tailings
storage facility/evaporation dams allowed for in the BFS.
    o    Dewatering Pumping System. The pumping system, supplying the water for the treatment trials,
         forms part of the field trials. Specialised, self-supporting, flexible hose, supplied by Hose
         Manufacturers South Africa (Pty) Ltd (Hose Manufacturers), is being field tested for the planned
         Prieska vertical lifts. Hose Manufacturers have developed the Deepset Hose (Boreline 400) able
         to self-support to a vertical lift of 1,000m. The Prieska Project dewatering assembly uses an 18.5kW
         borehole pump, attached to 3-inch diameter flexible hose, with a 378m vertical head as a single-
         lift, (Figure 3). This arrangement is the first such application under trial globally.

Figure 3: (LHS) Boreline 400 flexible hose suspended in the Hutchings Shaft, with a 378m vertical lift. This is the longest, single-lift
pumping setup using self-supporting flexible hose under trial in the world. (RHS) The 18.5kW Vansan submersible bore pump being
lowered in the Hutchings Shaft.

    o    Evaporator Field Trials. On completing the water treatment trials, pilot-scale trials of the proposed
         mechanically assisted evaporation assembly are planned. The BFS assumptions relied on field
         trials using 15KW evaporator units. Trials using 75kW and 90kW evaporator units are planned.
         Results from the trials are expected to refine the number of and improve the operating efficiency
         expected from the evaporation units to be installed.

aim to test 75kW and 90kW units as the next phase of the program.

Optimisations - Several opportunities to improve the Base Case Plan were identified during the BFS
process. Some of these opportunities are now being followed up and are expected to significantly
improve the overall project economics and project risk profile. The optimisation process is expected to
be completed by Q4 2019, resulting in a refined mining plan, ready for execution and that also
incorporates recommendations collected from key service providers and suppliers now being engaged
as part of the preparation for project execution. These opportunities being followed up include:

    o    the enterprise mapping and optimisation process. Whittle Consulting (Pty) Ltd (Whittle) has
         developed proprietary software that enables them to map the whole Mine-to-Market value chain
         and then simultaneously vary key value drivers in the chain until optimal combinations are
         identified that optimise the whole value chain. Fundamental parameters such as cut-off grades,
         mining sequence, mining rates, targeted metal recoveries, mill throughput rates, targeted grind
         sizes, feed blends, product specifications, product logistics routes and variances in metal prices
         are all considered as one integrated system to derive a series of optimal business scenarios.

         This enterprise optimisation process is expected to significantly improve project economics whilst
         also mapping out key business processes to aid operational control and a better understanding
         of the real value drivers unique for the Prieska Project business plan. Whittle has a demonstrated
         track record of having dramatically improved base case plans, with previous projects having
         achieved in the order of 10% - 30% improvement in net present value (NPV) from their base cases.

   o     review and refinement of the processing plant flowsheet and layout. The processing plant layout
         is being reviewed with the aim of refining and reducing its footprint and simplifying the layout to
         make the facility more easily operable. Several service providers are being considered to assist
         with this review.

   o     mine design and scheduling refinements. Mine design layout, sequencing and scheduling
         refinements continue to be made as part of the enterprise optimisation process.

Negotiation of key supply contracts and securing long lead time items - The negotiations for key supply
contracts and to secure long lead time plant and equipment are now being advanced. Activities are
being targeted to ensure the project is ready for execution by year-end and to take advantage of
potential savings in capital expenditure that can be secured with early down payments for critical items
of plant and equipment. Key contracts under consideration include:

   o   obtaining grid power from the national power utility, Eskom: whilst Eskom has approved the
       Company to undertake the power connection works as a self-build program, administrative
       connection charges and power tariffs are yet to be finalised;

   o   commissioning the next phase of renewable energy supply studies: a collaboration agreement
       with juwi Renewable South Africa (Pty) Ltd is already in place that provides the framework for
       advancing the plan to have over 50% of the project power needs supplied from renewable
       energy sources (refer ASX release 5 March 2019);

   o   securing water supply infrastructure and tariffs;

   o   placement of orders or option down-payments for long lead time items: suitable rock hoisting and
       materials transportation winders, as well as ball mills have been identified that, if secured early,
       would result in significant improvements in the project execution timeline and the mine
       construction cost;

   o   engagement of project management contractors;

   o   engagement of key workstreams service providers; and

   o   the marketing of copper and zinc concentrates.

Developing in-house project execution capacity – Various entities are being considered to assist with
managing the project execution and supplementing the Orion owner’s team responsible for executing
the BFS. A detailed project execution strategy is to be formulated, along with preparation of work
package scopes of work and documentation to enable the engagement of key service providers once
the project receives construction approval.

Infrastructure Studies

Power Supply – As previously reported, the national power utility, Eskom, has already approved the
Company’s plan to self-build the upgrade of the nearby Cuprum sub-station in order to be supplied with
the required 38 MVA of electric power (refer ASX release 26 June 2019). The Company now awaits
Eskom’s proposed power connection costs. An application was also submitted to Eskom for immediate
access to 15MVA of temporary power from the Cuprum sub-station. This power would be used during
the Project’s construction period prior to the 38 MVA connection becoming available. Confirmation of
this temporary connection is expected during Q3 2019.

Mining Right Applications

Post the end of the June Quarter, on 3 July 2019, the Repli Environmental Authorisation was granted by
the Department of Mineral Resources. In accordance with the National Appeal Regulations, the
Company has notified all registered Interested and Affected Parties of their right to appeal this decision,
within 20 days of being notified. Any such appeal must be lodged directly to the Department of
Environmental Affairs. At the time of writing, the Company was not aware of any appeal having been
lodged. The Repli Mining Right grant is expected during Q3 2019. The approval for the Vardocube
Environmental Application and Mining Right is also expected later this calendar year.

Deep Sulphide Resource

A re-assessment of the Inferred Mineral Resources Cu 117kt at 1.14% and Zn 417kt at 4.08% 10 (making up
36% of the estimated Deep Sulphide Resource) was undertaken during the Quarter to determine the most
efficient way to upgrade these resources to an Indicated Mineral Resource level of confidence. A drilling
program was formulated and will be included to the exploration drilling campaign planned to test
potential extensions of the Deep Sulphide Resource (Figure 5).

Figure 5: Longitudinal section of the Deep Sulphide Mineral Resource showing potential extensions to the Deep Sulphide Mineral
Resource.

Drill planning was carried out in consultation with mineral resource consultants Z-Star and is based on
geological knowledge of the Deep Sulphide Deposit and data distribution. Initial drilling will test areas
within the Inferred Mineral Resource considering the mine plan, minimum mining widths and cut-off
grades. Focus of the initial phases of drilling will be on the south-eastern section of the deposit as drill
targets promise thicker and higher-grade mineralisation as compared to the north-western section (Figure
6). Drilling will be conducted from underground drill platforms from the existing exploration drives and will
commence upon completion of dewatering and quipping of these levels (Figure 7).

south-eastern section of the Deep Sulphide Resource.

Figure 7: Cross-section AB as indicated on Figure 6, showing planned underground drilling designed to test the upper and lower
mineralised zones.


+ 105 Mineral Resource

Only 50% of the current Supergene Sulphide Resource in the +105 Mineral Resource estimate falls within
the Indicated Resource category, being Cu 10kt at 1.54% and Zn 19kt at 3.05% 11. A lack of data in the
southwestern portion resulted in this part of the Mineral Resource being classified at an Inferred level of
confidence (Figure 8). The Company plans to upgrade this Inferred Mineral Resource to an Indicated
level by infill drilling from the existing +105 level underground mine development. Figure 8 shows the
distribution of the different resource categories in the +105 Mineral Resource with existing and planned
drill hole intersections. Figure 9 illustrates the planned drilling from the +105m Level.

Figure 8: Supergene +105 Inferred Mineral Resource map showing planned underground drilling.

Figure 9: Cross-section showing planned infill drilling on the +105 Inferred Mineral Resource.

A total of 770 meters of drilling is planned for 11 drill holes. Utilising two drill rigs, the drill program can be
completed within three months from start date.

Near-Mine Projects

The near-mine projects are those projects within prospecting rights held by Repli, Repli (Doonies Pan),
Vardocube and Bartotrax (Figure 6). VMS deposits worldwide tend to occur in clusters, and apart from
the giant Prieska Deposit, five smaller deposits occur on the near-mine project areas. These include
Annex, explored by Anglovaal between 1969 and 1981, and three deposits on Doonies Pan (Kielder)
explored by Newmont South Africa between 1976 and 1979, referred to as the PK1, PK3 and PK6 Deposits
(Figure 10).

Figure 10: Surface plan showing the prospecting rights over and adjacent to the Prieska Project, and the location of the Annex and
Kielder (PK1, PK3 and PK6) deposits.

The geological map of the Near Mine Area has been updated by integrating the new SkyTEM TM airborne
magnetic data and field mapping (refer ASX release 16 January 2019) (Figure 11). The current
interpretation suggests the prospective horizon to be developed over some 20km on the north-western
and south-eastern strike extent of the Prieska Deposit, the western and eastern strike extent of the Annex
Deposit, the Ayoba Discovery and in the Magazine Antiform. In addition to this target horizon, several
SkyTEMTM (AEM) anomalies were identified for follow-up work (refer ASX release 25 February 2019). Soil
sampling over the AEM anomalies is in progress.

Figure 11: Updated geological plan showing near-mine prospective horizons based on surface geology and aeromagnetic data.

Soil Sampling

During the Quarter, soil samples were collected (Figure 12). The samples are currently being screened to
-80 micron and analysed using a handheld XRF analyser. Sample results will be incorporated in the
prioritisation of the AEM anomalies prior to ground Time Domain Electromagnetic surveys and diamond
drilling.

Figure 12: Aeromagnetic maps covering the Near Mine Prospecting Rights with soil sample surveys completed and in progress plotted.

Regional Exploration (South Africa)

Overview of Regional Activity

The Company maintains a substantial and prospective land holding in the Areachap Belt (Figure 13). The
Areachap Belt is analogous to other Proterozoic mobile belts hosting major VMS and magmatic Ni-Cu-
Co-PGE deposits.

VMS deposits almost always occur in clusters or “districts” associated with volcanic spreading centres,
with four such centres having been identified in the Areachap Belt. In addition to the Near Mine Project,
the Company is also prospecting for VMS deposits on the Masiqhame Prospecting Right (Figure 13). The
Kantienpan and Boksputs Zinc-Copper Deposits are the two most prominent known VMS deposits on the
Masiqhame Prospecting Right.

Similarly, world-class nickel deposits tend to also occur in clusters both on prospect and regional scale.
Within these intrusive centres, a small number of the intrusions tend to host the best mineralisation
depending upon the intrusion magma-flow dynamics and timing of magmatic sulphide immiscibility and
transport. Several mafic intrusive bodies with nickel and associated metals are known on the Namaqua-
Disawell Prospecting Rights (Figure 13). The setting of mineralisation has been confirmed to be analogous
to other orogenic-hosted, deep-seated magma conduit complexes such as Kabanga (Tanzania), Nova
(Australia), Ntaka Hill (Tanzania), Akelikongo (Uganda), and Limoeiro (Brazil). Conduit style mineralisation
is currently the top priority global target for magmatic Ni-Cu-PGE sulphide exploration.

Figure 13: Regional geology map of the Areachap Belt showing prospecting rights held by, or currently under option to, the Company,
and noted mineral occurrences as per published data from South African Council for Geoscience.

Namaqua Disawell Project Area

Overview
The Jacomynspan Deposit (Figure 14) was discovered by Anglo American Prospecting Services (AAPS) in
1971. Resource drilling was carried out to a depth of 900m over 1.3km strike distance by AAPS, with
disseminated nickel-sulphide mineralisation having been intersected with widths varying between 30 to
70m (refer ASX release 14 July 2016). Two other Ni-Cu deposits, Area 4 and Rok Optel, were investigated
during the 1970s by AAPS, Newmont, Phelps Dodge and Hoch Metals. Subsequent and prior to the
Company obtaining the prospecting and mining rights, various companies including Anglovaal, Glencor,
Gold Fields and Namaqua Nickel explored the area. African Nickel and the Company conducted
Airborne Electromagnetic (AEM) Surveys over the Prospecting Right (refer ASX release 1 February 2018).
The Company followed up a number of AEM anomalies with ground Time Domain Electromagnetic
surveys and prioritised the Rok Optel and Area 4 prospects for follow-up work (refer ASX release 3 July
2018). The Company drilled four diamond drill holes at Rok Optel while the Area 4 targets still remain to
be tested (refer ASX release 24 October 2018).

Area 4 Soil Sampling
Infill soil sampling on the Area 4 grid as part of an orientation survey and preparation for future surveys
were carried out during the Quarter (Figure 14). Two hundred samples were collected bringing the sample
line spacing over the prospect down to 120m with a sample spacing of 20m (Figure 15).

Figure 14: Simplified geology map of the Namaqua – Disawell Prospecting Rights showing the localities of known Ni-Cu prospects.

Figure 15: Soil sampling survey over Area 4 overlain on an AEM image.

Masiqhame Project Area

Contiguous to the north of the Namaqua-Disawell Project, this project is defined in terms of the
Masiqhame tenement holding and includes the Kantienpan and Boksputs Zn-Cu VMS deposits. With its
known VMS deposits, numerous Cu-Zn mineral occurrences and regional geological setting, the area
offers potential for new VMS Zn-Cu and magmatic Ni-sulphide discoveries. It is common for VMS districts
to have small Zn-Cu deposits clustering close to a large deposit where on the Masiqhame Prospecting
Right, the larger deposit is still to be discovered.

Soil sampling and mapping was undertaken during the Quarter. The soil samples were collected over and
along the strike of the Kantienpan Deposit and following the interpreted paleo-seafloor setting (Figure 16)
(refer ASX release 1 February 2018). The survey currently covers 5.7km of strike length. Screening and
analysis of the samples are ongoing.

Figure 16: Aeromagnetic map showing soil sampling completed over and along strike of the Kantienpan Zn deposit.

Marydale Gold-Copper Project (Witkop)

In addition to the Prieska Project, the Agama transaction gives the Company exploration rights over the
Marydale Gold-Copper Project located 60km north of the Prieska Project.

No field work was carried out during the Quarter on the Marydale Gold-Copper Project.

Australian Projects

Fraser Range – Nickel-Copper Projects (Western Australia)

Orion maintains a sizeable tenement package in the Fraser Range Province of Western Australia which
Independence Group NL (ASX: IGO) is currently earning into via a Joint Venture Agreement (JVA, refer
ASX release 10 March 2017).

Orion has been informed by IGO that a drilling program has commenced to test two high priority targets
selected on the basis of ground geophysics and geochemistry carried out by IGO. The projects being
prioritised for drill testing are North West Passage for intrusive hosted Ni-Cu and Pike Prospect where
potential exists for both Ni-Cu Intrusive mineralisation and VMS Cu-Zn mineralisation.

Walhalla Gold and Polymetals Project (Victoria)

On 11 August 2015 the Company announced to the ASX that it had entered into a sale agreement with
Centennial Mining Ltd (Centennial) for Centennial to acquire the Company's Walhalla Project mining
licence 5487 (MIN 5487). The original sale agreement contained a number of conditions that were
required to be satisfied before the transfer of MIN 5487 could be effected. For various reasons, these
conditions are unlikely to be satisfied and Centennial, acting through its Administrators, are not
contending that Centennial has any right, title or interest in MIN 5487 or that the original sale agreement
remains on foot. As a consequence, MIN 5487 remains under the ownership and control of the
Company.

the recent Placement was received. The balance of Tranche 2 funds, being $2.15M, are expected to be

Capital Raising and BEE ownership re-structure

On 16 April 2019 the Company announced a pivotal $8M capital raising underpinned by a group of high-
profile South African investors as part of a proposed restructure of the Company’s Black Economic
Empowerment (BEE) equity participation at project level, achieving accelerated compliance with the
ownership aspects of South African Mining Charter III (MC3).

Placement

The $8.0M capital raising comprises the issue of 200.9M fully paid ordinary share (Shares) at an issue price
of $0.04 per Share, together with one free attaching option for every two Shares issued (100.47M options
at an exercise price of $0.05 and an expiry date of 31 October 2019) (Options), to be conducted via a
placement to sophisticated and professional investors (Placement). The Options will not be quoted on
the ASX or the Johannesburg Stock Exchange (JSE).

The Placement includes approximately $4M placed to experienced South African BEE entrepreneurs, of
which $2M is being placed to incoming BEE equity investors who will also invest at the Prieska Project level.

The Placement will occur in two stages, being:
         -   Tranche 1 – 117.23M Shares and 58.61M Options, using the Company’s 15% placement capacity
             under ASX Listing Rule 7.1 to raise $4.69M. On 23 April 2019, Orion issued 50.63M Shares in the
             Company at $0.04 per Share and 25.31M Options, to raise $2.03M and on 30 April 2019, the
             Company issued 66.60M Shares in the Company at $0.04 per Share and 33.30M Options, to raise
             $2.66M, finalising Tranche 1 of the Placement; and
         -   Tranche 2 – 83.71M Shares and 41.85M Options, to raise $3.35M (which was approved at a general
             meeting of Orion shareholders held on 7 June 2019).

As part of the Placement, Tembo Capital Mining Fund II LP and its affiliated entities (Tembo Capital),
continued support of Orion through subscribing for $2M in Tranche 1 of the Placement. In addition to the
support obtained from South African BEE entrepreneurs and Tembo Capital, other key existing
shareholders have supported the Placement and the proposed BEE transactions.

Following completion of Tranche 1 of the Placement, the Company obtained shareholder approvals for
the Placement at a General Meeting of shareholders held on 7 June 2019. On 19 July 2019, Orion issued
30.0M Shares in the Company at $0.04 per Share and 15.0M Options, to raise $1.2M, resulting from a
receipt of funds from investors for Tranche 2 commitments. The Company has received commitments for
the balance of Tranche 2 (being $2.15M) and these Shares and Options are expected to be issued shortly.

BEE Restructure

The proposed BEE restructuring transactions entail existing BEE shareholders in Orion’s subsidiary, Repli
Trading No 27 (Pty) Ltd (Repli), which owns the Prieska Project with a Mining Right pending, exchanging
their 26.7% holding in Repli for JSE listed Orion Shares. A new BEE company (BEE HoldCo) will then acquire
a 20% shareholding in Repli, facilitated by way of Orion vendor funding.

The members of BEE HoldCo will have the entitlement to provide their proportionate share of Prieska mine
development costs on equal terms with the other shareholders of Repli. Although Repli has five years to
implement the BEE ownership obligations to achieve MC3 compliance, the proposed BEE restructuring
will satisfy the important ownership component of the MC3 compliance immediately.

The members of BEE HoldCo and Orion have agreed to accelerate the establishment of Employee and
Community trusts, each of which will hold a 5% ownership interest in Repli.

New BEE

Orion has entered into a Memorandum of Agreement with the BEE entrepreneurs (comprising Black Star
Minerals (Pty) Ltd (Black Star) and Kolobe Nala Investment Company (Pty) Ltd (KNI)) to establish two BEE
HoldCo’s, each owned as outlined below:

The establishment of the BEE HoldCo’s and the proposed acquisition of the 20% interest in Repli and 20%
of Orion’s interest in the Jacomynspan Project, is expected to be completed shortly. Details of the terms
of the acquisition of the 20% shareholding in Repli and 20% of Orion’s interest in the Jacomynspan Project
will be released once definitive agreements have been finalised.

BEE HoldCo members have demonstrated their commitment and financial capacity to complete the
transaction by agreeing to subscribe for $2M in the Placement referred to above.

Founding BEE Interests Exchanged for Orion Shares
The founding BEE partners of the Prieska Project have signed agreements with Orion to relinquish their
shares in Repli and other Areachap projects in exchange for approximately 135M JSE-listed Orion Shares.

The proposed BEE restructure transactions (relating to both the introduction of the New BEE entrepreneurs
and the share exchanges of the founding BEE partners) are subject to conditions that are customary for
transactions of this nature, including execution of definitive transaction agreements and applicable
board and regulatory approvals.

Anglo American sefa Mining Fund – Preference Share Redemption

On 4 March 2019, the Company announced it had reached agreement with the value-adding South
African institutional investor, Anglo American sefa Mining Fund (AASMF) to redeem Preference Shares
held by AASMF in one of Orion’s key project subsidiaries for shares in Orion. Under the agreement, AASMF
agreed to the redemption of the Preference Shares, in exchange for Orion Shares, the ASX and JSE listed
parent company of Repli (Share Exchange Agreement).

Under the terms of the Share Exchange Agreement and following the receipt of Orion shareholder
approval at a general meeting held on 7 June 2019, on 7 July 2019, Repli, a 73.33% owned subsidiary of
Orion, voluntarily redeemed the Preference Shares in consideration for Orion issuing the Shares to AASMF.

The Company obtained shareholder approval for the issue of Shares under the Share Exchange
Agreement at a General Meeting of shareholders held on 7 June 2019 and on 7 July 2019, the Company
announced that the issue of Shares to AASMF had been completed.

AASMF subscribed for 15.75M redeemable preference shares in Repli in November 2015 at a subscription
price of ZAR1 per redeemable preference share (ZAR15.75M (~A$1.58M)) (Preference Shares) as part of
a seed capital investment with the previous owners of the Prieska Project.

In satisfaction of the redemption amount payable by Repli to AASMF of ZAR25.05M (~A$2.05M), in
connection with the voluntary redemption of the Preference Shares by Repli, on 5 July 2019, Orion issued
77.57M Shares to AASMF at a deemed issue price of $0.0323 per Share.

Appointment of New Non-Executive Directors

During the Quarter, the Company announced the appointment of two highly experienced South African-
based mining executives who have specific knowledge and skill in the South African mining industry.

Godfrey Gomwe
Mr Godfrey Gomwe has extensive experience as an executive in the metals and mining industries. He is
the former Chief Executive Officer of Anglo American plc.’s Thermal Coal business, where his
responsibilities included oversight over Anglo’s Manganese interests in joint venture with BHP. Previously
Executive Director of Anglo American South Africa until August 2012, his career included roles as Head of
Group Business Development Africa, Finance Director and Chief Operating Officer of Anglo American
South Africa. Previously, Godfrey was Chairman and Chief Executive of Anglo American Zimbabwe
Limited. He also served on a number of Anglo American Operating Boards and Executive Committees
including Kumba Iron Ore, Anglo American Platinum, Highveld Steel & Vanadium and Mondi South Africa,
the latter two in the capacity of Chairman.

Tom Borman
Mr Tom Borman is a respected and highly experienced global mining executive who served more than
11 years working for the BHP Billiton Group in various senior managerial roles, including that of Chief
Financial Officer of an Australian-listed mining company. He also held senior roles in strategy and business
development and served as the project manager for the merger integration transaction between BHP
Limited and Billiton.

After leaving BHP Billiton in 2006, Mr Borman joined Warrior Coal Investments (Proprietary) Limited, where
he formed part of the executive team which established and consolidated the portfolio of assets which
became the Optimum Group of companies. Optimum listed on the Johannesburg Stock Exchange in
2010 and was subsequently acquired by Glencore for R8.5 billion in March 2012.

Concurrent with the appointment of Mr Gomwe and Mr Borman, Michael Hulmes stepped down as a
non-executive director, due to his increased commitments as an executive in a new role elsewhere. The
Directors thank Michael for his significant contribution during the Feasibility Study period and wish him well
in his new role.
