ARM Ferrous
Iron Ore division
Prices
Average realised US dollar export iron ore prices
were 7% lower on a free on board (FOB) equivalent
basis at US$116 per tonne (1H F2021: US$125 per
tonne) as the 62% iron ore fines index price
dropped from peak levels above US$230 per tonne
at the beginning of July 2021 to below US$100 per
tonne in November 2021 driven by a slowdown in
steel production in China in the second half of
the 2021 calendar year. The iron ore lump
premium also collapsed to US$1.63 per tonne in
September 2021, the lowest level since April 2017,
but recovered and stabilised towards the later part
of the six months under review.
Volumes
Total iron ore sales volumes, export sales volumes
and local sales volumes decreased marginally (by
1%) compared to 1H F2021 at 8.2 million tonnes,
6.7 million tonnes and 1.5 million tonnes
respectively. The ratio of lump to fines sales
volumes was 58:42 (1H F2021: 59:41).
Iron ore production was 11% higher at 8.3 million
tonnes (1H F2021: 7.5 million tonnes). Production
in the corresponding period was lower as the
mine had full product stockpiles at the end of
30 June 2020.
Unit costs
On-mine production unit costs for the iron ore
division increased by 10% mainly due to higher
waste-stripping costs being allocated to working
costs at Khumani Mine coupled with above
inflation increases in the costs of explosives,
diesel and maintenance. These increases were
partially mitigated by the 11% increase in
production volumes.
On-mine production unit costs at Khumani Mine
increased by 11% to R329 per tonne (1H F2021:
R297 per tonne) while on-mine production unit
costs at Beeshoek Mine increased by 5%.
Khumani Mine's on-mine unit cash costs (which
exclude run-of-mine ore stock movements, include
capitalised waste-stripping costs and certain
non-cash adjustments) were flat at R353 per
tonne (1H F2021: R351 per tonne) demonstrating
the impact of more waste-stripping costs being
allocated to on-mine production costs. Beeshoek
Mine's unit cash costs increased by 1% to
R376 per tonne (1H F2021: R372 per tonne).
Unit cost of sales for the iron ore division were
11% higher mainly due to the increased on-mine
production costs (as discussed above) and higher
freight rates, which increased by 86%. Sales and
marketing costs which are determined based on
realised iron ore prices were lower owing to the
decline in iron ore prices.
Consistent and sustainable water supply to
Khumani Mine remains a concern given the
delays and challenges experienced refurbishing
and upgrading the Vaal Gamagara Water Supply
System in the Northern Cape. Assmang is in
extensive engagement with the Department
of Water Affairs and the Minerals Council
South Africa to collaboratively ensure that the
refurbishment and upgrade programme is
progressed to ensure sustainable water supply
to the region.
Logistics
Export sales volumes were 58 000 tonnes
lower at 6.7 million tonnes for 1H F2022
(1H F2021: 6.7 million tonnes). This was mainly
due to Transnet Freight Rail (TFR) being impacted
by derailments and various other operational
challenges. TFR's reduced performance resulted
in on-mine stockpiles reaching maximum capacity
which is expected to impact production volumes
at Khumani Mine in the 2H F2022. This has also
resulted in very low port stockpiles at Saldanha
Port, where vessels are loaded on a just-in-time
system.
Assmang and the country's iron ore exporters
continue to engage regularly with Transnet to
address these operational challenges, seeking
improvement for both rail and port operations.
Capital expenditure
Capital expenditure for the iron ore division
was R1 152 million on a 100% basis (1H F2021:
R962 million). The increase in capital expenditure
was mainly due to higher infrastructure investment
and fleet replacement. Capitalised waste-stripping
costs were R554 million (1H F2021:
R542 million).

Prices
The average US dollar prices realised for
manganese ore increased in 1H F2022 as the
average 44% manganese ore (CIF Tianjin) and
37% manganese ore (FOB Port Elizabeth) index
prices increased by 26% and 16%, respectively.
Manganese ore prices were supported by low
port inventories (particularly in China) together
with logistics challenges in the 2021 calendar
year. Pollution and emission reduction mandates
also raised the demand for higher grades of
manganese ore, resulting in strong price
divergences between ore grades.
Volumes
Total manganese ore sales volumes decreased
by 6% to 1.8 million tonnes (1H F2021: 1.9 million
tonnes). Export sales volumes were 6% lower at
1.7 million tonnes (1H F2021: 1.8 million tonnes)
while local sales volumes were 70 000 tonnes
(1H F2021: 65 000 tonnes).
The decrease in export sales volumes was
mainly due to derailments caused by rain-related
flooding, wash-away of rail lines and various
operational challenges at TFR, including cable
theft on the Gqeberha corridor and Eskom
challenges in the same region.
Assmang and the rest of the manganese export
producers continue to engage Transnet weekly to
seek improvement of the rail and port systems.
Production volumes at Black Rock Mine were 5%
higher at 2.1 million tonnes (1H F2021: 2.0 million
tonnes) as the Gloria Mine ramps up production.
Unit costs
On-mine unit production costs and cash unit
costs at the Black Rock Mine decreased by 6%
to R658 per tonne (1H F2021: R698 per tonne for
unit production costs and R696 per tonne for unit
cash costs). The decrease in unit costs is largely
attributable to the dilution of fixed costs as a
result of increased production volumes. Unit
production costs are expected to reduce
further in real terms as the Black Rock Mine is
modernised and optimised as part of the Black
Rock and Gloria projects.
Logistics
Delivery by TFR and Transnet Port Terminals
(TPT) was negatively impacted by operational
challenges as discussed above. Additional rail
and port capacities have been secured through
the ports of Gqeberha 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 division
increased by 4% to R1 083 million (100% basis)
(1H F2021: R1 008 million) of which R278 million relates to the modernisation and optimisation
of Gloria Mine (1H F2021: R504 million) and
R175 million related to the Black Rock Project
(1H F2021: R270 million).
Projects
The Gloria Project was negatively impacted by
difficult ground conditions and complex geology
during mining development. With 87% of the
approved R2.97 billion spent on the Gloria Project
at 31 December 2021, the project is 90.3%
complete and is forecast to be completed by
August 2022. The surface plant system has been
successfully commissioned and was handed
over to operations in September 2021. The
underground plant and crusher construction is
on schedule with handover to operations planned
for May 2022.
The Black Rock Project was also negatively
impacted by difficult ground conditions mainly
at the Nchwaning III Tip 2 system. The project
is currently 98% complete and is expected to
be finalised in August 2022 at a total project
cost of R7.3 billion.
The Nchwaning II Graben system was
successfully commissioned and handed
over to operations during 1H F2022.
Both the Gloria and Black Rock projects'
completion dates are aligned with the production
ramp-up plan which has been carefully
synchronised with Transnet rail and export
capacity.

Prices
US dollar index price for high carbon manganese alloys increased by 91% mainly due to a temporary
shortage of alloys in the market to meet the
increased steel production mainly from Europe,
the United States and India.
Volumes
High-carbon manganese alloy production including
molten metal at Cato Ridge Works decreased by
9% to 61 000 tonnes (1H F2021: 67 000 tonnes).
This was mainly because of the civil unrest
experienced in KwaZulu-Natal in July 2021,
ore variability and poor reductant quality.
Medium-carbon manganese alloy production at
Cato Ridge Alloys was 4% higher at 29 000 tonnes
(1H F2021: 28 000 tonnes).
High-carbon manganese alloy export sales
at Cato Ridge Works decreased by 27% to
27 000 tonnes (1H F2021: 37 000 tonnes) due
to the reasons highlighted above. Medium-carbon
manganese alloy sales at Cato Ridge Alloys
decreased by 20% to 24 000 tonnes (1H F2021:
30 000 tonnes).
High-carbon manganese alloy production at
Sakura decreased by 14% to 91 000 tonnes
(1H F2021: 106 000 tonnes) mainly due to an
unplanned shut down of a furnace following
multiple transformer failures. Sakura had to
declare Force Majeure to its customers due
to the lower production volumes. High-carbon
manganese alloy sales at Sakura decreased by
31% to 71 000 tonnes (1H F2021: 103 000 tonnes).
Unit costs
Production unit costs at Cato Ridge Works were
11% higher at R14 190 per tonne (1H F2021:
R12 764 per tonne) as a result of lower production
volumes, inflationary increases and furnace
efficiency challenges. Cash costs at Cato Ridge
Works (which include fixed cost charged out of
working costs during periods of no production),
increased by 15% to R14 225 per tonne
(1H F2021: R12 415 per tonne).
Production unit costs at Cato Ridge Alloys were
34% higher at R24 543 per tonne (1H F2021:
R18 324 per tonne) primarily driven by higher
molten metal input prices, informed by increased
high-carbon manganese alloy US dollar index
prices.
Production unit costs at Sakura increased 11%
to MYR4 215 per tonne (1H F2021: MYR3 792 per
tonne). This was mainly driven by lower production
volumes following the unplanned furnace outage
and significant increases in manganese ore and
reductant prices.

ARM Platinum
Prices
Higher US dollar PGM prices, particularly
platinum (10% higher) and rhodium (20% higher),
were partially offset by the stronger rand versus
US dollar exchange rate. The average rand per
6E kilogram basket price for Modikwa and Two
Rivers rose by 6% and 7% to R1 284 600 per
kilogram (1H F2021: R1 215 364 per kilogram)
and R1 201 888 per kilogram (1H F2021:

Two Rivers and Modikwa mines recognise
revenue using provisional pricing. The sales price
of the concentrate is determined on a provisional
basis at the date of the sale, with adjustments
made to the sales price based on movements in
the discounted forward commodity prices up to
the date of final pricing. Post refining and delivery,
adjustments are made to reflect final pricing.
Any differences between the provisional and final
commodity prices after the reporting period result
in the next reporting period's earnings being
impacted by a mark-to-market adjustments.
Realised mark-to-market adjustments
A portion of the ARM Platinum receivables
as at 30 June 2021 was realised at lower prices
following the sharp decline in rhodium and
palladium prices in the first three months of the
period under review, which resulted in realised
negative mark-to-market adjustments as shown
in the table below.
Unrealised mark-to-market adjustments
Revenue related to open sales at 31 December
at Two Rivers and Modikwa mines was initially
recognised using provisional prices and
subsequently revalued at 31 December per
the table below.

Modikwa Mine
Volumes
Tonnes milled improved by 34% which, combined
with a 1% rise in head grade, increased
production volumes by 37% to 152 379 6E PGM
ounces (1H F2021: 111 295 6E PGM ounces).
Production volumes were lower in the comparable
period due to industrial action and two fatalities
which resulted in the loss of approximately
20 000 6E PGM ounces in 1H F2021.
Unit costs
Production unit costs reduced by 13% to
R13 528 per 6E PGM ounce (1H F2021:
R15 590 per 6E PGM ounce) and were
11% lower on a rand per tonne basis at
R1 706 (1H F2021: R1 923). This is largely
attributable to the 37% increase in production.
Capital expenditure
Capital expenditure at Modikwa Mine
(100% basis) rose by 28% to R440 million
(1H F2021: R343 million). Of this, 25% related
to fleet refurbishment and critical spares, 20% to
the South 2 Shaft deepening project, 10% to the
finalisation of the chrome recovery plant and 9%
to the installation of a Proximity Detection System
for the mining fleet.
Projects
North Shaft Project – the remaining electrical
reticulation work is on track for completion in
1H F2023.
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 steady-state
production. South 2 Shaft achieved a run rate of
60 000 ore tonnes per month for 1H F2022, which
is above the 55 000 ore tonnes target. The mine
has normalised its production rate in 1H F2022
with the focus remaining on the development
of the declines and associated infrastructure.
Chrome Recovery Plant (CRP) – the project
was approved for construction in 1H F2020.
Nameplate capacity will be 288 000 tonnes of
chromitite concentrate per annum. The CRP
project has been completed and the first chrome
was dispatched towards the end of 1H F2021.

Two Rivers Mine
Volumes
PGM production volumes decreased by
3% from 150 304 6E PGM ounces in 1H F2021
to 146 524 6E PGM ounces in 1H F2022. The
grade at Two Rivers Mine remains a constraint
as various mining cuts are taken in the multi-split
reef areas to optimise grade as far as possible.
Following the accelerated development of the
declines, mining flexibility is improving and
enabling a better mining mix. Two Rivers Mine
lost approximately 1 000 6E PGM ounces
following a safety stoppage after the fall-of-ground
fatal accident in September 2021.
Unit costs
Two Rivers Mine production unit cost increased
by 10% to R964 per tonne milled (1H F2021:
R877 per tonne). The rand per 6E PGM ounce
operating cost increased by 16% to R11 015 per
ounce (1H F2021: R9 518 per ounce), primarily
due to the utilisation of stock which negatively
impacted operating costs.
Capital expenditure
Of the R572 million spent at Two Rivers Mine,
30% was spent on the Two Rivers Merensky
Project as approved in F2021.
Deepening of the declines at Main and North
shafts along with electrical and mechanical
installations comprised a further 25% of total
capital expenditure. Additionally, 19% was spent
on the tailings storage facility and 8% on mining
fleet replacement.
The plant expansion project, which will add
40 000 tonnes per month milling capacity, was
approved in December 2019. After a two-month
delay related to Covid-19, and steel shortage due
to the metalworkers' strike, the additional mill is
now commissioned with full ramp-up expected
to be achieved towards the end of the third
quarter of F2022.
Construction of the new tailings storage facility
was completed in October 2021 and final
commissioning is expected in the second
half of F2022.
Projects
Two Rivers’ shareholders approved the Two
Rivers Merensky Project which involves mining
of the Merensky Reef. Total estimated capital
expenditure for the project is R5.7 billion
(100% basis) which will be spent over three
years. The project targets annual production
of 182 000 6E PGM ounces, 1 600 tonnes
nickel and 1 300 tonnes of copper.
Merensky underground mining is planned to
commence in the fourth quarter of F2022, with
the plant set to be commissioned in the second
quarter of F2024.
The project is running slightly behind schedule on
surface earthworks; however, this has no effect on
the critical paths or schedule of the mining works.

Nkomati Mine
Care and maintenance
Nkomati Mine was placed on care and
maintenance since 15 March 2021. Various
options regarding the way forward for the mine
are under evaluation.
Estimated rehabilitation costs
At 31 December 2021, the estimated
undiscounted rehabilitation costs attributable
to ARM were determined to be R679 million
(30 June 2021: R679 million) excluding VAT.
The discounted rehabilitation costs attributable
to ARM were determined to be R608 million
(30 June 2021: R596 million). The R12 million
increase in the discounted liability was due to
unwinding interest recognised against the liability.
At 31 December 2021, R136 million (attributable
to ARM) in cash and financial assets were
available to fund rehabilitation obligations for
Nkomati Mine. The resulting attributable shortfall
of R472 million is expected to be funded by ARM.
Nkomati Mine's estimated rehabilitation costs
continue to be reassessed as engineering designs
evolve and new information becomes available.
ARM Coal
Prices
US dollar prices for thermal coal increased in
1H F2022 largely due to constrained global
coal supply, which was hampered by logistics
constraints, adverse weather conditions and an
increase in demand as Asian Liquefied Natural
Gas (LNG) prices reached record levels
(prompting a switch from gas to coal). Prices
were further positively impacted by a ban on
coal exports in Indonesia which was subsequently
lifted in January 2022.
Goedgevonden Mine's average received export
US dollar price increased by 159% to US$118 per
tonne in 1H F2022 (1H F2021: US$46 per tonne)
on higher market prices and increased export
of high-grade quality. PCB average received
export US dollar price increased by 150% from
US$46 per tonne in 1H F2021 to US$115 per
tonne in 1H F2022.
Approximately 64% of export volumes at
Goedgevonden Mine comprised high-quality
coal, while PCB exports of high-quality coal
totalled 72%.

Volumes
Increased health and safety measures together
with the vaccinations drives at the operations have
reduced the impact of Covid-19 on production
volumes for both Goedgevonden Mine and PCB.
Total sales volumes reduced by 1% as
underperformance from TFR resulted in full
product stockpiles at Goedgevonden Mine.
ARM's attributable saleable production remained
flat at 0.75 million tonnes in 1H F2022 compared
to the comparative period.
Unit costs
On-mine production unit costs per saleable
tonne increased by 7% to R537 per tonne
(1H F2021: R503 per tonne) due to inflationary
increases related to on-mine expenditure.

Volumes
Export sales volumes were 17% higher at
4.87 million tonnes (1H F2021: 4.15 million
tonnes). Domestic sales volumes declined by
68% from 1.7 million tonnes to 0.54 million tonnes
due to the expiration of certain domestic contracts.
Production at the PCB operations was negatively
impacted by TFR's underperformance resulting
in high product stockpiles. ARM's attributable
saleable production was 0.98 million tonnes
in 1H F2022 compared to 1.24 million tonnes
in 1H F2021.
Unit costs
Production unit costs per saleable tonne
increased by 31% from R472 per tonne in
1H F2021 to R619 per tonne in 1H F2022.
The increase in unit costs is due to the reduction
in saleable production together with a reduction
in the capitalisation of pre-stripping costs.
