Commenting on the production results, Tharisa CEO Phoevos Pouroulis, said:
“Through our continued focus on mining and processing improvements and optimisation we have
delivered an excellent operational performance for FY2017. We see more potential in the year ahead
and will be embarking on unlocking greater value through the successful transition to owner mining,
primarily focusing on reducing dilution and improving feed grades from within the open-pit.
Furthermore, our organic optimisation projects should yield additional recoveries, lowering our unit
costs and enhancing our production going forward. We are excited by opportunities within the
mining sector and look to grow our business through strategic investments and co-operation
agreements leveraging off our existing infrastructure.”
Safety
Safety remains a priority and Tharisa continues to strive for zero harm at its operations. There were
no lost time injuries during the quarter and consequently we recorded an improved LTIFR of 0.07 per
200 000 man hours worked. Tharisa Minerals was awarded three safety awards in 2017: the Best
Safety Performance and Best Improved Performance awards at Mine Safe 2017, and an award from
the Mine Health and Safety Council for 2 000 fatality free production shifts.

Mining
Tharisa’s reef mining operations achieved a new record in Q4 FY2017 with 1.3 Mt of reef mined.
Notably the Cr2O3 run of mine grade improved to 18.4% with the continuous focus on improvement
in the drill, blast and reefing operations.
Total waste of approximately 2.5 Mm3 was moved during the quarter at a stripping ratio of 6.6 on a
m3:m3 basis. The waste stripping remained below the LOM average of 9.7 and this will be a focus
area going forward to ensure that sufficient reef is available in the optimal blend for the processing
plants. Key to achieving the required waste stripping is the drill and blast operations and Tharisa has
insourced its drilling operations and purchased additional drill rigs to achieve the required stripping
ratio.
With throughput into the plant exceeding nameplate capacity, the stockpiles ahead of the
processing plants total 307.7 kt, with a target of 400.0 kt to ensure optimal reef layer blending, feed
grade and throughput consistency into the plants.
Tharisa mined 5.0 Mt of ROM in FY2017, which is 3.9% higher than in FY2016 and in excess of the
plant processing nameplate capacity of 4.8 Mt. The PGM rougher feed grade, however, reduced
from 1.65 g/t to 1.56 g/t as more weathered ore was included in the ROM following the road
diversion and mining of that area to expand the mining footprint. The Cr2O3 ROM grade was
effectively the same as the prior year.
The transition to an owner mining model, which included the transfer and employment of
approximately 900 mining contractor’s employees, was effective as of 1 October 2017. In addition
to the purchase of the contractor’s mining fleet, Tharisa Minerals supplemented the fleet with
additional drill rigs, excavators and mining equipment. Please refer to Tharisa’s announcement
dated 22 September 2017 for more details on the transaction.
Processing
Reef milled during the quarter was 8.4% higher at 1.3 Mt benefitting from the increased availability
and feed consistency of the ROM ore. The increase in reef milled together with the improvement in
PGM recoveries at 81.0% resulted in a 10.2% increase in PGM production at 39.0 koz (on a 6E basis).
Record chrome production of 360.5 kt was achieved, 83.5 kt of which was specialty grade
concentrates.
The high energy flotation circuit successfully commissioned at the Voyager Plant PGM recovery
circuit has been replicated in the PGM recovery circuit of the Genesis Plant. This circuit was
commissioned in August 2017. The benefit on the PGM recoveries from the Genesis Plant was,
however, offset by the lower PGM rougher feed grades as more weathered ore was processed.
A total of 4.9 Mt of reef was milled in FY2017, a 5.6% increase year on year. PGM production was
8.3% higher at 143.6 koz, marginally below FY2017 guidance of 147.4 koz, at an average recovery
rate of 79.7% in line with targeted recoveries of 80.0%. Chrome production at 1.3 Mt was in line with
market guidance and was up 7.0% with chrome recovery averaging 64.1%. Optimisation initiatives
planned should ensure that Tharisa achieves its targeted recovery of 65.0% for chrome
concentrates.
During Q4 FY2017, Tharisa concluded an agreement with Lonmin to operate its K3 UG2 chrome
plant. Arxo Metals, a subsidiary of Tharisa, commenced operating this plant effective 29 August
2017. The plant has produced 20.0 kt of UG2 chrome concentrate. Production from this plant is
expected to exceed 200 ktpa, the marketing and sales of which expands the basket of chrome
concentrates sold by Tharisa and leverages off its established logistics and marketing platforms.
Chrome concentrate inventories on hand as at 30 September 2017 was 78.7 kt.
Market update
The average PGM contained metal basket price for the three months ended September 2017 was
US$825 (ZAR10 866) per ounce, which is US$33 an ounce higher than the US$792 (ZAR10 443) per
ounce achieved in the quarter ended June 2017 and US$50 an ounce higher for the 2017 financial
year compared to FY2016. The higher basket prices reflect, in particular, the increase in spot
palladium prices, which surpassed the platinum price during the quarter.
With improved liquidity in the market during Q4 FY2017, contracted metallurgical grade chrome
concentrate prices increased 17% to US$172 per tonne from US$147 per tonne the previous quarter,
bringing the total average realised metallurgical chrome price during FY2017 to US$200 per tonne.
As at 29 September 2017, Chinese port stock levels were slightly above 2 Mt, or approximately two
months’ supply into the domestic Chinese ferrochrome and stainless steel industry.
The fundamentals of the global stainless steel market remain sound with continued growth forecast
in 2018, supporting demand for chrome units in the form of ferrochrome and chrome ores. Specialty
chrome concentrates, which comprised 24.3% of Tharisa’s total chrome concentrate production in
FY2017 and which supplies the chemical and foundry markets, continue to attract a premium of
more than US$30 per tonne above the contracted metallurgical chrome concentrate prices.
Outlook
Tharisa’s FY2018 production guidance is 150 koz PGMs and 1.4 Mt chrome concentrates, of which
approximately 350 kt will be specialty grade chrome concentrates.
Tharisa continues to focus on delivering operational improvements, and through additional
investment in R&D and innovation is geared to unlock even greater value for all stakeholders. The
near term focus will be on operational improvement and in-pit optimisation following the transition
to the owner mining model.
