Our various stakeholders have benefited from our
improved profitability and we continued to strengthen
our social licence to operate by supporting our
employees and host communities through these
difficult times.
Unit costs came under immense pressure across
operations owing to pressure on volumes and Covid-19-related measures and lockdown restrictions. As a
result, above inflation unit cost increases were
experienced at most of our operations.

Iron ore operations
Prices
Average realised US dollar export iron ore prices were
47% higher on a free on board (FOB) equivalent basis
at US$125 per tonne (1H F2020: US$85 per tonne)
driven by robust steel production in China coupled with
global iron ore supply shortages. Higher global coking
coal prices also drove a recovery in iron ore lump
premiums during 1H F2021. The operations were
opportunistic in response to the recovery in lump
premium prices increasing the ratio of lump to fines
sales volumes from 56:44 in 1H F2020 to 59:41 in
1H F2021.
Volumes
Total iron ore sales volumes increased by 6% to
8.2 million tonnes (1H F2020: 7.8 million tonnes).
Export sales volumes were 8% higher at 6.7 million
tonnes (1H F2020: 6.2 million tonnes) while local sales
volumes were at a similar level as 1H F2020 at
1.5 million tonnes.
Iron ore production was 20% lower at 7.5 million tonnes
(1H F2020: 9.3 million tonnes) due to full product
stockpiles in mid-2020 as a result of Covid-19-related
rail restrictions from April to June 2020, coupled with
abnormal rainfall in November to December 2020
which affected mining and plant operations.
Unit costs
On-mine production unit costs for the division increased
by 17% mainly due to lower production levels as
discussed above. On-mine production unit costs at
Khumani Mine increased from R253 per tonne in
1H F2020 to R297 per tonne in 1H F2021 while on-mine
production unit costs at Beeshoek Mine increased from
R227 per tonne to R265 per tonne in the same period.
Unit cost of sales for the division were 16% higher
following the increase in on-mine production unit
costs together with higher sales and marketing costs.
Sales and marketing costs are determined based
on average realised iron ore prices and were higher
due to the increase in realised iron ore prices as
discussed above.
Logistics
The performance of Transnet Freight Rail (TFR) and
Transnet Port Terminal (TPT) exceeded expectations
for the period under review assisted by high stockpile
levels at 30 June 2020 and collaboration between
Transnet and the industry in dealing with Covid-19-related challenges.
Capital expenditure
Capital expenditure for the iron ore division was
R962 million on a 100% basis (1H F2020: R863 million).
The increase in capital expenditure was mainly due to
higher capitalised waste stripping costs of R542 million
(1H F2020: R431 million).

Prices
After a brief spike in manganese ore prices during the
latter part of F2020, prices declined steeply and
remained under pressure for 1H F2021. When South
African production restarted after the Covid-19
lockdown, manganese ore prices came under pressure
touching lows of US$4.05/mtu for 44% manganese ore
in November 2020.
Volumes
Manganese ore sales volumes increased by 4% to
1.9 million tonnes (1H F2020: 1.8 million tonnes).
Export sales volumes were 4% higher at 1.8 million
tonnes (1H F2020: 1.7 million tonnes) while local sales
volumes were 65 000 tonnes (1H F2020: 53 000 tonnes).
Production volumes at Black Rock Mine were 2% lower
at 2.0 million tonnes, impacted by Covid-19-related
absenteeism, delays with the commissioning of the
Black Rock and Gloria projects and challenges with
labour shortages and poor equipment availability.
Unit costs
Black Rock Mine's on-mine production unit costs
increased by 18% to R698 per tonne (1H F2020:R591 per tonne). The increase in on-mine production
unit costs was mainly due to the decrease in production
volumes, above inflation increases in labour, electricity
and insurance costs, together with increased costs
associated with Covid-19 precautionary and
compliance measures. Labour cost increases were
driven by a higher head count arising from additional
shifts worked, increased long-term incentive expenses
for A to C Bands as well as higher costs associated
with Covid-19 absenteeism which resulted in 3 321
person days lost. Production unit cost improvements
expected from the Black Rock and Gloria projects were
not realised due to delays in the commissioning of
certain Black Rock Project and Gloria project systems.
Logistics (manganese ore export)
As noted, Transnet Freight Rail and Transnet Port
Terminal operations exceeded the expectations for the
six months. Rail and port capacities have been secured
through the ports of Port Elizabeth and Saldanha in line
with the ramp-up of Black Rock Mine until 2023. We
continue to engage with Transnet on rail allocation
beyond the current contractual period.
Capital expenditure
Capital expenditure for the manganese ore operations
on a 100% basis was R1 008 million (1H F2020:R1 188 million) of which R504 million (1H F2020:
R401 million) related to the modernisation and
optimisation of Gloria Mine within Black Rock Mine
as approved in F2018. R270 million (1H F2020:
R335 million) related to the Black Rock Project.
The Black Rock and Gloria projects have been delayed
by six months due to Covid-19 lockdown measures
which resulted in a slow return to site. The Gloria
Project is now estimated to be completed in May 2022
compared to the original plan of November 2021. As a
result, we expect a R200 million budget overrun on the
originally approved budget, bringing the total project
expenditure to R2.9 billion. The Black Rock Project is
now expected to be completed in July 2022 with over
expenditure of R0.3 billion raising the total expenditure
to R7.2 billion.
The Black Rock and Gloria projects aim to modernise
and expand the mine by increasing volumes and
flexibility to produce different products and improve
efficiencies. Ramp-up of the Black Rock Mine is being
closely synchronised with Transnet's rail availability and
export capacity expansion is being considered.
At 31 December 2020, R2.0 billion had been spent on
the Gloria Project which is 69% complete and
R6.7 billion had been spent on the Black Rock Project
which is 93% complete.

Prices
Average realised prices for high carbon manganese
alloy and medium carbon manganese alloy at Cato
Ridge Works decreased by 12% to US$937 per tonne
(1H F2020: US$1 063 per tonne) and by 11% to
US$1 364 per tonne (1H F2020: US$1 530 per tonne),
respectively.
Volumes
Due to lower demand in the global seaborne market,
high carbon manganese alloy production at Cato Ridge
Works was reduced by 14% to 67 000 tonnes
(1H F2020: 78 000 tonnes). Medium carbon manganese
alloy production at Cato Ridge Alloys was 18% lower
at 28 000 tonnes (1H F2020: 34 000 tonnes).
High carbon manganese alloy export sales at Cato
Ridge Works decreased by 3% to 37 000 tonnes
(1H F2020: 38 000 tonnes) while medium carbon
manganese alloy sales at Cato Ridge Alloys rose
30% to 30 000 tonnes (1H F2020: 23 000 tonnes).
High carbon manganese alloy production at Sakura
(100% basis) decreased to 106 000 tonnes (1H F2020:128 000 tonnes) mainly due to an unplanned shut down
resulting from critically low stock levels of manganese
ore which could not be exported from South Africa
as a result of the Covid-19 lockdown. High carbon
manganese alloy sales at Sakura decreased by 6% to
103 000 tonnes (1H F2020: 110 000 tonnes).
Unit costs
High carbon manganese alloy production unit costs at
Cato Ridge Works were 12% higher at R12 764 per
tonne (1H F2020: R11 402 per tonne) as a result of
lower production volumes.
Medium carbon manganese alloy production unit costs
at Cato Ridge Alloys were in line with the prior period at
R18 324 per tonne (1H F2020: R18 265 per tonne).
High carbon manganese alloy production unit costs at
Sakura decreased 1% to MYR3 792 per tonne
(1H F2020: MYR3 841 per tonne). This was mainly
driven by lower manganese ore prices and successful
implementation of cost saving initiatives.
Capital expenditure
Capital expenditure for Cato Ridge Works increased by
138% to R30 million (1H F2020: R15 million) mainly due
to the rebuild of Furnace 5.

ARM Platinum
Prices
Higher US dollar metal prices, particularly palladium
(35%) and rhodium (162%), contributed significantly to
Modikwa and Two Rivers Mines' improved 1H F2021
results. Coupled with the weaker rand/US dollar
exchange rate, the average rand per 6E kilogram
basket price for Modikwa and Two Rivers rose by 78%
and 76% to R1 215 364 per kilogram (1H F2020:
R682 945 per kilogram) and R1 120 965 per kilogram
(1H F2020: R638 305 per kilogram), respectively.
The average realised rand nickel price realised at
Nkomati Mine was marginally higher while the rand
chrome price was 3% lower.

Two Rivers Mine
Headline earnings at Two Rivers more than trebled to
R1 279 million (1H F2020: R357 million) mainly due
to a 76% increase in the rand PGM basket price.
Chrome concentrate sales volumes increased by
28% to 123 554 tonnes as a result of higher chrome
yield. This, combined with a 5% improvement in the
rand chrome price, resulted in the chrome cash
operating profit improving 37% to R67 million
(1H F2020: R49 million).
Volumes
PGM production volumes increased by 9% after
flotation challenges experienced in July 2019 were
resolved. PGM volumes, therefore, increased from
138 199 6E PGM ounces in 1H F2020 to 150 304 6E
PGM ounces in 1H F2021.
The Two Rivers Mine grade remains a constraint as
various mining cuts are taken in the multi-split reef
areas to optimise grade as far as possible. Accelerated
sinking is progressing well, with the completion of level
12 in Main Shaft. PGM grades from North Shaft have
improved slightly with priority given to processing this
ore at the concentrator plant.
Unit costs
Two Rivers Mine achieved a below inflation production
unit cost increase of 4% to R877 per tonne milled
(1H F2020: R847 per tonne). The rand per 6E PGM
ounce cost decreased by 6% to R9 518/oz (1H F2020:
R10 083/oz), primarily due to higher PGM production
volumes.
Capital expenditure
Of the R552 million capital spent at Two Rivers Mine,
17% was for mining fleet replacement and
refurbishment. Deepening Main and North Shafts along
with electrical and mechanical installations comprised
24% of total capital expenditure. The remaining capital
spend was for the plant expansion and tailings
storage facility.
The plant expansion project, which will add
40 000 tonnes per month milling capacity, was
approved in December 2019. After the contractor
placed orders for certain long-lead items, site
mobilisation began in July 2020 although Covid-19
restrictions have delayed the forecast project
completion date by three months to December 2022.
The additional mill is now expected to be commissioned
in the second quarter of F2022 with full ramp up to
360 000 ounces 6E PGMs per annum now expected
to be achieved in the third quarter of F2022.
Construction of the new tailings storage facility was
suspended due to Covid-19 lockdown regulations.
Construction resumed in May 2020 as Covid-19
lockdown restrictions were eased. We expect the
project to be finalised in the first quarter of F2022.
Delay in the commissioning of the new tailings storage
facility is not expected to affect operations.
Projects
The ARM board of directors has approved the Two
Rivers Merensky Project which involves mining of the
Merensky reef at Two Rivers Mine. Total capital
expenditure for the project is expected to be
approximately R5.7 billion (100% basis) to be spent
over three years. Construction is planned to commence
in July 2021 with plant commissioning expected in
second quarter 2023.
Studies indicate that over the life of mine, 52 million
tonnes at an average milled feed grade of 2.9g per
tonne (on a 6E ounce basis) will be mined and
processed. Annual steady state production of
182 000 6E PGM ounces, 1 600 tonnes nickel, and
1 300 tonnes of copper is expected once the project is
fully ramped up. With this project, Two Rivers Mine is
forecast to be positioned in the bottom half of the
industry cash cost curve.
An update will be provided once commercial features
and governance processes for approval of the project
are finalised.

Modikwa Mine
Modikwa reported headline earnings of R462 million
(1H F2020: R343 million). The temporarily improved
purchase-of-concentrate agreement expired on
31 December 2019. The impact thereof on headline
earnings was more than offset by the rise in the rand
basket price.
Volumes
Tonnes milled declined by 24% which, combined with a
5% decrease in head grade, reduced production
volumes by 29% to 111 295 6E PGM ounces (1H F2020:
155 812 6E PGM ounces). Mining volumes were
impacted by the Covid-19 lockdown and restrictions
with a proportionally larger impact on stoping than on
development, given the higher labour intensity on
stoping. The resultant lower stoping to development
ratio gave rise to a decrease in head grade. More ore
milled from historical low grade stockpiles also
contributed to reduced head grades.
In addition, Modikwa Mine lost approximately
5 200 6E PGM ounces following two fatal accidents
(one each in September and October 2020). An
additional estimated 14 800 6E PGM ounces were
lost towards the end of 1H F2021 due to unprotected
industrial action by National Union of Mineworkers
(NUM) affiliated employees following the
misrepresentation of housing-related benefits which
were overpaid in the fourth quarter of F2020 and
incorrectly claiming that the mine owed them monies
under the Temporary Employer/Employee Relief
Scheme (TERS). All employees returned to work and
the matter was resolved.
Unit costs
Production unit costs rose by 39% to R15 590 per 6E
PGM ounce (1H F2020: R11 222 per 6E PGM ounce)
and were 30% higher on a rand per tonne basis at
R1 923 (1H F2020: R1 477). Lower production volumes
and additional Covid-19 expenditure impacted
production unit costs.
Capital expenditure
Capital expenditure at Modikwa Mine (100% basis)
rose by 8% to R343 million (1H F2020: R317 million). Of
this, 21% related to fleet refurbishment and critical
spares, 40% for construction of the chrome recovery
plant, 9% for the North Shaft deepening project and
5% for the South 2 Shaft deepening project.
An update of these projects is as follows:
- North Shaft Project – level 9 decline belt extension
and bulkhead infrastructure was completed as
previously communicated with development and
equipping on track against the revised schedule.
- South 2 Shaft Project – establishing a decline system
south of the current South 1 Shaft infrastructure. The
first phase to enhance mining flexibility and
contribute to the production build-up of the mine is
complete and South 2 Shaft is ramping up to steadystate
production. South 2 Shaft achieved a run rate
of 50 000 ore tonnes per month for 1H F2021, which
is below the 55 000 ore tonnes target, mainly due to
Covid-19 restrictions. The operation is on course,
with the opening of more working areas, to achieve
the planned target of 55 000 ore tonnes per month.
The mine is ramping up production as more
production stopes are being opened and envisaged
to be at a normalised production rate in 2H F2021.
The Chrome Recovery Plant (CRP) project was
approved for construction in 1H F2020. The project
comprises constructing a chrome spiral plant to
recover chromitite concentrate from the UG2
concentrator plant tailings stream. Nameplate capacity
will be 288 000 tonnes of chromitite concentrate per
annum. As a result of Covid-19 labour protocols, the
commissioning of the plant is now scheduled for the
first quarter of F2022.

Nkomati Mine
Scaling down of Nkomati Mine is progressing. The
halting of production was delayed by lockdown
restrictions and mining optimisations which marginally
extended the remaining production duration.
Production is now expected to cease at the end of
March 2021 and not September 2020 as previously
planned after which the mine will be placed on care
and maintenance in preparation for closure.
Nkomati Mine reported headline earnings of
R280 million (1H F2020: R211 million headline loss),
primarily due to fewer once-off negative items than in
1H F2020.
Chrome concentrate sales declined by 40% and,
combined with a 13% reduction in average realised
US dollar chrome prices, resulted in cash operating
profit from chrome decreasing to R4 million (1H F2020:
R45 million).
Estimated rehabilitation costs
As at 31 December 2020, the estimated undiscounted
rehabilitation costs attributable to ARM were
determined to be R620 million (30 June 2020:
R614 million) excluding VAT. The R6 million increase
compared to the amount that was provided for as at
30 June was mainly due to unwinding interest.
At 31 December 2020, R108 million (attributable) cash
and financial assets were available to fund rehabilitation
obligations for Nkomati Mine. The resulting attributable
shortfall of R486 million is expected to be funded firstly
from cash generated by the mine during production
scale-down, and subsequently by the partners.
Nkomati Mine's estimated rehabilitation costs continue
to be reassessed as engineering designs evolve and
new information becomes available, as well as when
approvals are secured for a revised environmental
management plan and water-use licence.
Volumes
Waste mined volumes reduced as part of the rampdown
plan and tonnes milled decreased by 1% to
3.60 million tonnes (1H F2020: 3.65 million tonnes).
Nickel production volumes increased by 19% to
6 426 tonnes (1H F2020: 5 386 tonnes). The mine had
10 556 tonnes of nickel concentrate in stock at
31 December 2020 (30 June 2020: 23 264 tonnes).
Unit costs
On-mine production unit costs in 1H F2021 increased
by 3% to R386 per tonne (1H F2020: R375 per tonne).
Cash costs net of by-products per nickel pound
produced were 64% lower at US$2.38/lb (1H F2020:
US$6.65/lb). The improvement was due to reduced
mining expenditure, higher sales volumes and
increased by-product credits due to improved byproduct
prices, particularly palladium.

ARM Coal
Prices
Thermal coal prices remained largely depressed in
1H F2021 after the sharp decline in 2H F2020. This was
mainly due to decreased demand owing to the
Covid-19 pandemic and related global lockdowns.
India and China reduced thermal coal imports
considerably on the back of reduced demand and
prioritisation of local coal production.
Prices improved towards the end of 1H F2021 with
China increasing its demand for non-Australian thermal
coal, supported by positive sentiment on a global
economic recovery. Demand continued to reduce in
European markets on greater coal-to-gas fuel
switching, rising renewable energy generation and
weaker power demand.
Goedgevonden Mine's average received export
US dollar price declined 21% to US$46 per tonne in
1H F2021 (1H F2020: US$58 per tonne) on lower
market prices and increased export of low-grade
quality (as domestic demand decreased). Participative
Coal Business' (PCB) average received export
US dollar price decreased 19% from US$57 per tonne
in 1H F2020 to US$46 per tonne in 1H F2021.
Around 62% of export volumes at Goedgevonden Mine
were high-quality coal, while PCB exports of highquality
coal totalled 63%.

Volumes
Increased health and safety measures to prevent the
spread of Covid-19 and manage its impacts continued
to affect production volumes in the review period for
both Goedgevonden and PCB, but to a lesser extent. In
addition, production in the period under review was
impacted by the new mining contractor's slow ramp-up.
Total sales volumes reduced by 7% as lower offtake
of domestic coal by Eskom and underperformance
from TFR resulted in full product stockpiles at
Goedgevonden Mine.
ARM's attributable saleable production was 0.75 million
tonnes in 1H F2021 (1H F2020: 0.83 million tonnes).
Unit costs
On-mine production unit costs per saleable tonne
rose by 10% to R503 (1H F2020: R458) largely due
to the 9% reduction in saleable production as
discussed below.

Volumes
Domestic sales volumes declined by 43% from
2.96 million tonnes to 1.7 million tonnes due to reduced
demand from Eskom. Export sales volumes were
12% higher at 4.15 million tonnes (1H F2020:
3.72 million tonnes).
In addition to Covid-19 restrictions, production at the
PCB operations was impacted by TFR's
underperformance and reduced offtake from Eskom,
resulting in high product stockpiles.
PCB successfully commissioned a second dragline at
Tweefontein Mine in the latter part of 1H F2021. This is
expected to improve both production and cost
management.
ARM's attributable saleable production was 1.24 million
tonnes in 1H F2021 compared to 1.29 million tonnes in
1H F2020.
Unit costs
Production unit costs per saleable tonne decreased by
7% from R507 in 1H F2020 to R472 in 1H F2021 mainly
as a consequence of lower waste volumes mined.
