Introduction

RBPlat benefited from the recovery and strengthening of the macro PGM market fundamentals in 2019, resulting in a healthy basket price. However, the domestic environment remained challenging given the general elections in May 2019; the local union leadership elections; wage negotiations; an unpredictable Eskom power grid; a dearth of trackless competence and skills; and the expectations of our doorstep communities. From an operational perspective, the year represented a continued transitionary phase across the Group as Styldrift moved from a project environment to commercial operating status, and BRPM was required to maintain steady results despite a rapidly depleting South shaft Merensky Reserve.

Our key operational focus for the year was on:

While we achieved pleasing improvements in our injury frequency rates, regrettably, despite all our efforts to keep our people safe, we did not achieve our goal of zero fatalities (see the Chair's review and the human capital section of this report).

By year-end the bulk of the LOM infrastructure required to support the ongoing ramp-up of Styldrift to 230ktpm by the third quarter of 2020 was in place; Styldrift had delivered 1 600kt of ore; BRPM's South shaft had met and exceeded its UG2 production target of 20ktpm; Maseve concentrator 160ktpm MF2 expansion progressed to detail design phase with long-lead items ordered; and construction on both tailings storage facilities had commenced.

While we achieved significant production and construction milestones at BRPM, Styldrift and the concentrating facilities, the overall volume and cost performance across our operations was disappointing, despite a 12.5% and 9.0% increase, respectively, in milled tonnes and 4E metals in concentrate. 4E metals in concentrate amounted to 401koz (6.7% below the lower end of our guidance) and the unit cost per 4E ounce exceeded guidance by 6.3% at R14 139. Addressing the underlying contributors to this, which is a priority for the business, is discussed in more detail in this capital.

Eskom load curtailment operational response strategy

Currently, our primary operational strategy is to minimise the impact of load curtailment by restricting certain mining and metallurgical processes, specifically ore hoisting and crushing, during load curtailment periods. To date, this strategy has proven effective in dealing with Stage 1 and 2 restrictions, by allowing our mining and milling activities to continue uninterrupted.

We manage Stage 3 restrictions by suspending processing at our Maseve concentrator and preferentially maintaining production at our BRPM concentrator to mitigate ounce losses.

When Stage 4 restrictions are in place we maintain mining operations and suspend all metallurgical processing activities. Restrictions in excess of Stage 4 necessitate the suspension of all operational processes other than essential services.

We are currently reviewing the potential to synchronise our on-site emergency generating capacity with the mine electrical reticulation grid to improve our ability to effectively manage load curtailment in the short term. Longer term, more cost-effective and energy-efficient solutions are being investigated as part of our broader sustainability strategy.

Styldrift operation

Progress towards the 230ktpm ramp-up at Styldrift

Ore reserve development, commissioning of infrastructure, onboarding of skilled employees, and the optimisation of the operational systems required to achieve the third quarter 2020 230ktpm ramp-up milestone, remained the primary objectives of the project during the reporting period.

Styldrift's ramp up continued to progress steadily during 2019, however, as can be expected in a new operation in ramp-up, planned progress was impacted by several technical and operational challenges.

The challenges

The slower than planned performance was underpinned by challenges stemming from:

This was exacerbated by geology and geotechnical requirements due to the lack of IMS flexibility within the operation as the mine ramps up.

Because we did not have all the infrastructure in place at Styldrift to move ore to a central point until year-end (in particular the strike belts on 600 level and ore handling infrastructure on 642 level), our fleet had to travel beyond the specific parameters we have set down for how far a load haul dump (LHD) vehicle should travel to achieve optimal performance. This resulted in increased mining production cycles and impacted the availability of equipment, which was further exacerbated by the lack of skilled mechanics and auto-electricians. These deficiencies frequently resulted in below plan performance and high fleet maintenance costs.

Twelve of the required strike belts, two on-reef dip belts and the associated life of mine (LOM) ore handling infrastructure are now in place, and the surface and underground stores facilities are nearing completion. We have also made good progress during the second half of the year with the onboarding of artisans and skills training initiatives (see human capital) to address our trackless fleet maintenance requirements. Ninety percent of the trackless fleet required to support steady state production is on site, with the remaining units planned for delivery during the first half of 2020.

Spare IMS section ore reserves play a pivotal role in establishing the operational flexibility necessary to effectively mitigate the impact of geology and geotechnical requirements on a mining operation. The Styldrift design allows for this capacity in two ways, namely spare in-stope IMS panels and an additional four spare IMS sections on completion of the 230ktpm footprint. However, given that this flexibility will only be fully attained on completion of the project footprint, Styldrift remains exposed to production risks because of geology on the mineable face length and associated mining efficiencies. The intersection of known fault systems in the north, north-eastern and western mining sections, combined with a footwall shear zone in the south west, were no exception, further contributing to lower than planned crew performance in these areas during the reporting period.

By year-end we had achieved significant improvements in trackless fleet availability and tip-to-face tramming distances, as guided in our interim results, and are confident that our operating platform for 2020 is well-established, equipped and staffed to deliver on our goal of achieving 230ktpm run rate by the third quarter of 2020.

Safety

Despite an encouraging reduction in our TIFR and SIFR and achieving 1.5 million fatality-free shifts at Styldrift by October 2019, the mine unfortunately recorded a non-mining-related fatality in November 2019.

Implementing Fulco

Fulco, which involves equipping and manning a mine 24 hours a day, seven days a week, was implemented at Styldrift in February 2019. We believe that Fulco is the right approach to mechanised mining as it ensures that our investment in expensive machinery is optimally utilised and that we extract the best possible value from our investment in a mechanised mine.

Production

Stoping square metres for the reporting period increased by 61.8% compared to 2018, with tonnes delivered increasing by 42.0% or 473kt to 1 600kt from 1 127kt in 2018. Total development decreased by 2.9% to 6.8km in line with the project infrastructure requirements as the 230ktpm capital project footprint nears completion.

Total tonnes milled amounted to 1 625kt compared to 2018. This combined with a 9.3% increase in built-up head grade yielded a 56.9% and 59.1% increase in 4E and platinum metals in concentrate. 4E metal production amounted to 160koz with platinum metal production of 105koz.

Cash operating costs

Cash operating cost for the reporting period amounted to R2 651 million, with cash operating cost per tonne milled and per 4E ounce equating to R1 632 and R16 504, respectively. The cash operating cost of R16 504 exceeded our market guidance in the second half of 2019 by 6.5%. Key contributors to this increase were:

Capital expenditure

Capital expenditure amounted to R1 430 million, made up of R1 225 million for expansion capital (mining and concentrator infrastructure), R80 million replacement capital and R125 million stay-in-business (SIB) capital.

Expansion capital expenditure of R1 225 million was in line with project requirements and progress during the year under review. During the second half of the year we also initiated the North and South decline replacement projects, with a total of R80 million being spent for the year.

SIB expenditure increased to R125 million equating to a 25% year-on-year increase, which was aligned with trackless fleet and section strike belt forward move requirements.

Total expenditure for the project to date amounts to R12.87 billion. During the course of the year further capital was approved for the purchase of additional trackless fleet, optimisation of shaft logistics and on-reef ore handling infrastructure and training facilities. This together with the 2020 expenditure estimate of R0.8bn results in an estimate at completion of R13.8bn. A detailed review of overall project scope and associated costs will be finalised during the first half of 2020.

BRPM operation

Having taken the decision at the beginning of 2019 to respond to pricing opportunities, in particular those of palladium and rhodium, by recommencing with mining UG2 at BRPM's South shaft we set ourselves a target of ramping up to 20ktpm by November 2019. We were able to achieve our target ahead of schedule when we delivered 20ktpm of UG2 from South shaft in the third quarter of 2019.

Production

Total BRPM development increased by 15.4% to 32.3km with the increase mainly attributable to increased working cost development, in line with ramping up of UG2 production at South shaft. Total square metres mined decreased by 2.1% to 411 thousand square metres, the decrease being mainly as a result of lower Merensky production from South shaft as reserves deplete.

BRPM delivered tonnes decreased by 1.7% to 2 229kt, with Merensky delivered tonnes decreasing by 11.0% to 1 640kt. UG2 delivered tonnes increased by 38.3% to 589kt in line with the recommencement of UG2 mining operations at South shaft. The reduction in Merensky tonnes at BRPM is directly attributable to the depletion of Merensky reserves at South shaft.

Total tonnes milled for the reporting period decreased by 3.3% on the back of lower delivered mining volumes. This combined with a 4.8% reduction in built-up head grade and lower associated recoveries yielded a 9.4% and 9.8% reduction in 4E and platinum metals in concentrate, respectively. 4E metal production equated to 241koz and platinum metal production to 156koz.

Cash operating costs

BRPM cash operating costs increased by 8.5% to R3 024 million compared to 2018. The increase is attributable to on-mine inflation and additional costs associated with the re-establishment of UG2 production at South shaft.

Key cost drivers were:

The 8.5% increase in cash operating costs combined with the 3.3% reduction in milled volumes, 4.8% lower built-up head grade and 1.3% lower recovery yielded unit cost increases of 12.2% and 20.0% per tonne milled and 4E ounce respectively. Cash cost per tonne milled amounted to R1 361 and cash cost per 4E ounce equated to R12 562.

Capital expenditure

BRPM capital expenditure for the reporting period amounted to R100 million, equating to a 2.5% reduction compared to 2018. R21 million was spent on Phase III replacement capital and R79 million on SIB. SIB as a percentage of working cost was 2.6%.

North shaft Phase III project

This project extends the shaft decline system and ancillary infrastructure from 10 level down to the mine boundary at 15 level. The completion of two belt extensions in the fourth quarter of 2019 and the purchase of two additional LHDs to improve machine availability has allowed the project to reach steady-state production of 2 500 tonnes a day. By year-end the project, which started in 2010, was completed with a R254 million saving against a budget of R1 409 million. We will initiate the project close out process in the first quarter of 2020.

Concentrators

The purchase of the Maseve concentrator allowed us to achieve organic growth and increase our tonnes milled by 12.5% year-on-year. However, currently the recoveries at the Maseve MF1 plant, which were 80.13% in 2019, are 4% lower than those at the BRPM concentrator, which achieved recoveries of 84.34%. We have completed a feasibility study into the upgrading of the Maseve concentrator to MF2, which, in addition to improving recoveries, will increase the plant's capacity to 160ktpm from its current 110ktpm. The upgrading of the Maseve concentrator and an incremental increase at the BRPM concentrator will provide us with the concentrating capacity we need to process the South shaft UG2 production beyond 2020 and the Styldrift steady-state production of 230ktpm.

BRPM concentrator production tonnes milled reduced by 5.5% or 158kt to 2 689kt compared to 2018, with the concentrator 4E recovery reducing by 1.0% to 84.34%. Concentrator recovery was impacted by overall lower built-up head grades, Eskom grid instability and the loss of the secondary mill for the period March to May 2019.

The extension of the tailings dam facility at Maseve is well under way for completion in 2020 (see Natural capital) and the extension of the BRPM facility commenced in the fourth quarter of 2019 and planned for completion in the fourth quarter of 2021.

The way forward and what to expect from our operations in 2020

Our Chief Executive Officer has referred to our restructuring efforts in his review, which are designed to ensure RBPlat is fit for purpose in the long term and to reduce costs and increase efficiencies in the short to medium term. Our key focus area in this regard will be to ensure the effective resourcing and ongoing alignment of our operations in line with the growing contribution of Styldrift, at the same time as the mining mix at BRPM extracts more lower grade UG2. The contribution of UG2 mining at BRPM will increase to approximately 35% of our overall production during 2020 and is expected to reach 50% during 2023.

Operational flexibility at BRPM remains a key challenge as South shaft Merensky reserves are depleted and the shaft transitions to mining the more complex UG2 ore body. Productivity and mining efficiencies on the UG2 reef, which is characterised by a thinner, undulating UG2 band, are lower than the Merensky reef. The lower grades of the UG2 will create upward unit cost pressures at BRPM, which during 2020 will only partially be offset by the increasing scale of the business as well as operational reorganisation. We therefore expect BRPM cost inflation to be consistent with mining inflation of 8% in 2020 as we opportunistically extract UG2 due to the rapid access and negligible capital requirements of doing so. BRPM grades and recoveries will be consistent with 2019 as South shaft continues to operate and extract margin-bearing UG2, despite the lower grades and costs associated with this.

The ramp-up of Styldrift is expected to reach 230ktpm during the third quarter of 2020, delivering between 2.0Mt and 2.2Mt for 2020 as the remaining production and IMA sections are developed. During the year the increasing contribution from stoping teams will lead to an improved and more consistent delivered grade, but this will continue to be impacted by limited face flexibility, crew learning curves and the continued contribution of low grade on-reef development forming part of the ore stream until year-end.

We expect both Styldrift grade and recovery to improve as the relationship between stoping square metres and development approaches steady state.

As is typical during the ramp-up phase of a mine, during which all the fixed costs are incurred but the production volumes are not in place to absorb them, unit costs will therefore not reflect economy of scale benefits until we achieve steady state.

In line with Styldrift's ramp-up the Maseve plant has been commissioned and is operating as an MF1 concentrator at 110ktpm. This treatment plant was originally designed to operate as an MF2 concentrator and during 2020 is being upgraded to an MF2 configuration. This will result in improved recoveries and provide more flexibility and capacity to treat varying ore mixes post 2020, particularly with respect to UG2 should the prevailing market conditions continue.

Group production in 2020

Group production guidance for 2020, subject to any unforeseen operational disruptions and changes in market conditions, is forecast to increase to between 4.2Mt and 4.5Mt at a 4E built-up head grade of 3.90g/t to 4.00g/t, yielding 450koz to 485koz 4E metals in concentrate.

Unit cost guidance for the Group is forecast to be between R13 300 and R14 400 per 4E ounce.
