Sibanye-Stillwater Mineral Resources and Mineral Reserves declaration as at 31 December 2018
Sibanye-Stillwater (Tickers JSE: SGL and NYSE: SBGL - http://www.commodity-tv.net/c/search_adv/?v=298805) is pleased to report updated Group Mineral Resources and Mineral Reserves, as at 31 December 2018.
? Total group Platinum Group Metals (PGMs) Mineral Reserves increase by 4% from 44.261 Moz to 46.062 Moz, primarily due to ongoing reserve definition drilling at the Blitz Project at Stillwater, where approximately 3.294Moz of Mineral Reserves were added at a 2E PGM grade of 23.7 g/t
? Total group PGM Mineral Resources were stable at 204.373Moz
? Total Mineral Reserves at the SA gold operations were 12.108 Moz, a 9% year-on-year decline, primarily as a result of the restructuring of marginal operations (2.373Moz) and depletion (1.162Moz), partially offset by the successful conversion of Mineral Resources to Mineral Reserves at the Kloof operations (+1.204 Moz) and the inclusion of attributable (38.05%) DRDGOLD Mineral Reserves (2.245 Moz) following the sale of certain the West Rand Tailings Retreatment Project assets to DRDGOLD
? Total SA Gold Project Mineral Reserves decreased by 64% to 4.476 Moz primarily due to the sale of certain West Rand Tailings Retreatment Project (WRTRP) Mineral Reserves to DRDGOLD and the decision to cease further development at the Driefontein Depth Extension Project as part of a rigorous capital and economic review of the SA gold operations
? Total gold Mineral Resources increased by 12.789 Moz to 104.221Moz primarily due to the inclusion of DRDGOLD Mineral Resources attributable to SGL
? Total group copper Mineral Resources increased marginally to 18,795.8Mlb (an increase of 0.7%), due to the inclusion of the attributable Rio Grande Project Mineral Resources, following the successful transaction with Regulus Resources Inc. and Aldebaran Resources Inc.
All Group Mineral Reserves have been declared using a principle of three year trailing prices in line with SEC requirements. The rand gold price applied of R540 000/Kg is ~12% below current spot prices, the rand 4E PGM basket price applied of R12,694/4Eoz is ~35% below current spot prices; and the USD 2E PGM basket price applied of USD849/2Eoz is ~56% below current spot prices, demonstrating the robustness of the reserve figures under the current price environment, and the quality of the underlying mineral assets.
The Group Mineral Resources and Reserves underpin operations with a Life of Mine in excess of 20 years at both the Southern Africa (SA) and United States (US) PGM operations and approximately 14 years at the SA gold operations.
Neal Froneman, CEO of Sibanye-Stillwater Comments: "Our Mineral Resources and Reserves have been estimated in line with conservative pricing parameters, ensuring robust operational margins and greater operating flexibility, at current spot prices.
The increase in our PGM Mineral Reserve base, largely as a result of ongoing Mineral Reserve definition at Blitz is pleasing and confirms the world class quality of the Stillwater orebody, while our SA PGM operations continue to deliver, in line with expectations. The rigorous review of our SA gold operations during 2018, in particular certain marginal operating shafts, was necessary and although this has resulted in a decrease in total Mineral Reserves, it will enhance the resilience of the SA gold operations to short term economic fluctuations and create longer term sustainable production."
The recently completed transaction with DRDGOLD has successfully seen the first phase of the previously reported WRTRP being implemented by DRDGOLD, as part of their Far West Gold Recoveries (FWGR) project. This transaction has increased Sibanye-Stillwater''s exposure to mechanised, long life and low cost (R/t) surface mining operations, highly leveraged to the gold price.
Group Mineral Resources and Reserves by Operation
US PGM Operations
? Total 2E PGM Mineral Resources of 79.860Moz, a decrease of 0.75%.
? Total 2E PGM Mineral Reserves of 25.614Moz, an increase of 16.94%.
? Mineral Resources remain largely unchanged with mining depletions off-set by resource growth at the Blitz section of the Stillwater mine.
? The pleasing 17% increase in Mineral Reserve ounces was primarily in the Blitz project area of the Stillwater Mine, where the rapid expansion of the developed area provided a platform for increased reserve definition drilling. Higher than average 2E PGM grades were also encountered. The increase in Mineral Reserves supports the planned expansion of production from the Blitz area of the Stillwater Mine, which remains on schedule.
? Copper Mineral Resources increased by 0.72% to 18,795.8Mlb, and gold Mineral Resources by 3.75% to 6.558Mlb?s due the inclusion of 19.9% of the attributable Mineral Resources of the Rio Grande Project, owned by Aldebaran Resources Inc. This follows the conclusion of an arrangement with Regulus Resources Inc., Aldebaran?s holding company, whereby Aldebaran will obtain an option to earn in up to 80% of the company?s Altar Project, in
SA PGM Operations (Inclusive of Mimosa)
? Total 4E PGM Mineral Resources of 96.181Moz, a decline of 1.60%.
? Total 4E PGM Mineral Reserves of 20.448Moz, a decline of 8.54%.
? Total 4E PGM Mineral Resources declined marginally by 1.600Moz primarily due to mining depletion during 2018.
? The decline of 1.910Moz in Mineral Reserves is in line with expectations and Life of Mine extraction plans, and is principally attributed to
Depletion of 1.557Moz from mining activities during 2018
A 0.514 Moz decrease due to removal of sub-economic ounces at the end of Life of Mine as combined mine production volumes drop below economically sustainable levels.
SA PGM Projects
- Total 4E PGM Mineral Resources of 24,350Moz, remain unchanged from 2017.
SA Gold Operations
? Mineral Resources of 33.950 Moz, an increase of 1.166Moz (3.56%).
? Mineral Reserves of 12.108 Moz, a decline of 1.21Moz (9.11%).
? The increase in gold Mineral Resources is largely due to the inclusion of the attributable 38% share of the DRDGOLD Mineral Resources (3.787Moz), offset by a decrease of 2.621 Moz at the existing gold operations. This decrease was informed by depletions, the restructuring of marginal shafts at the Beatrix and Driefontein mines, which are currently subject of a Section 189A consultation process and may lead to downsizing or closure; as well as the sale of the WRTRP assets.
- The decrease in gold Mineral Reserves was largely a result of:
Depletion of 1,162Moz from mining activities during 2018
Restructuring of the marginal Beatrix 1 and Driefontein 2, 6 and 8 Shafts, resulting in 2.373Moz being removed from the Mineral Reserve base
Changes in pay limits (economic factors) resulting in 0.764Moz not being deemed economically viable to extract under current assumptions.
Geological and structural model adjustments at Beatrix 1 and Driefontein 1 & 5, and resulting geotechnical pillar adjustments (-0.865 Moz).
? These decreases were offset by:
Additional Mineral Reserves of 1.204Moz defined as a result of ongoing exploration and reserve delineation at the Kloof operations.
A further 2.245 Moz were added, based on the 38% attributable Mineral Reserves from of DRDGOLD following the successful completion of this transaction during 2018.
A detailed reconciliation of 2017 to 2018 SA Gold Operations Mineral Reserves is shown in the Table below.
SA Gold Projects
? Total gold Mineral Resources increased by 21.76% (11.387Moz) to 63.714 Moz. ? Total gold Mineral Reserves decreased by 63.95% (7.940Moz) to 4.476Moz.
During 2018 the transaction with DRDGOLD was completed whereby Sibanye-Stillwater sold certain of the WRTRP assets from Kloof and Driefontein to DRDGOLD in exchange for a 38% shareholding in DRDGOLD. As a result, the Company no longer reports these specific Mineral Resources and Mineral Reserves previously held under the WRTRP, but has reported attributable Mineral Resources and Mineral Reserves of DRDGOLD. The Mineral Resources of the Cooke portion of the WRTRP, which has been retained, remain unchanged at 2.245Moz. As a result of the transaction, no reserves are currently reported for the remaining portion of the WRTRP, while the economic feasibility of the remaining assets are being investigated.
In addition, a detailed capital review was undertaken of the Company''s capital projects during 2018. At current economic parameters, and considering capital prioritisation, a decision was made to cease further development of the Driefontein Depth Extension (DE) Project (1.707Moz Mineral Reserve declared in 2017), but to continue with the Kloof DE Project.
? Total gold project Mineral Resources increased by 11.387 Moz, primarily due to the inclusion of the attributable DRDGOLD underground Mineral Resources.
A detailed reconciliation of 2017 to 2018 SA Gold projects Mineral Reserves is shown in the Table below.
SA Uranium Operations and Projects
? U3O8 Mineral Resources of 78.692Mlb, a decline of 36.05%.
? No U308 Mineral Reserves have been declared, a decline of 96.083Mlb?s.
? The decline in Mineral Resources is directly attsributed to the sale of a portion of the WRTRP to DRDGOLD
- No uranium Mineral Reserves were declared following the sale of the Kloof and Driefontein tailings dams of the WRTRP to DRDGOLD. This uranium relates principally to the Cooke assets, which were excluded from the transaction, and are now reported as Mineral Resources only.
A detailed reconciliation of 2017 to 2018 Mineral Reserves is shown in the Table below.
Sibanye-Stillwater reports its Mineral Resources and Mineral Reserves in accordance with the SAMREC Code, the updated Section 12 of the JSE Listings Requirements and the SEC Industry Guide 7, which is aligned with the guiding principles of SOX. Altar, Marathon and Rio Grande Mineral Resources are compliant with NI 43-101 guidelines. In accordance with SEC requirements.
This Mineral Reserves and Mineral Resources declaration represents a condensed and consolidated summary of the full Sibanye-Stillwater Mineral Resources and Mineral Reserves declaration available in the Group Mineral Resource and Mineral Reserve Report, which will be published on 29 March 2019 and will be available at www.sibanyestillwater.com
In accordance with US Securities and Exchange Commission (SEC) guidelines and Sibanye-Stillwater reporting standards, approximate three-year average, rolling, historical commodity prices are assumed for the calculation of Mineral Reserves. An average exchange rate of R13.55/US$ and the following commodity prices were used:
Guided by a commitment to best practice corporate governance, the statement has been reviewed by each Region?s Technical Services. The South African Gold Operations was subjected to an external audit during 2018.
The Mineral Resources and Mineral Reserves are estimates at a particular date, and are affected by fluctuations in mineral prices, the Rand-US dollar currency exchange rate, operating costs, mining permits, changes in legislation and operating factors. Although all permits may not be finalised and in place at the time of reporting, there is no reason to expect that these will not be granted. However, the length of the approval process for such permits may have an impact on the schedules stated.
All statement figures are managed by Sibanye-Stillwater with the exception of those for Mimosa, and the attributable portion for DRD and Aldebaran Resources. Mineral Resources are reported inclusive of Mineral Reserves, and production volumes are reported in metric tonnes (t). Gold and uranium estimates are reported separately from each other; therefore, no gold equivalents are stated to avoid potential anomalies as a result of year-on-year metal price differentials. The Southern African PGM Operations statement are reported as 4E PGM, which consists of platinum, palladium, rhodium and gold. The US operations are reported as 2E PGM, which consist of platinum and palladium.
The individual proportions of the reported PGM?s are provided in the tables below.
All financial models used to determine Mineral Reserves are based on current tax regulations at 31 December 2018. Mineral Resources were declared at a 10% increase relative to the Mineral Reserves metal price.
Mineral Resources are inclusive of Mineral Reserves. Rounding off of figures may result in minor computational discrepancies. Where this happens, it is not deemed significant.
