Sibanye Mineral Resources and Mineral Reserves update for the Gold and Platinum Divisions

(firmenpresse) - Sibanye Mineral Resources and Mineral Reserves update for the Gold and Platinum Divisions


Westonaria, 3 March 2017: Sibanye Gold Limited (JSE: SGL & NYSE: SBGL - http://www.commodity-tv.net/c/mid,5428,Company_Updates/?v=297063) is pleased to report updated Group Mineral Resources and Mineral Reserves, declared as at 31 December 2016, which following the acquisitions of Aquarius Platinum Limited and the Rustenburg Operations in 2016 includes maiden Platinum Group Metals (4E PGM) Mineral Reserves and Resources.
Salient points:
- Total Gold Mineral Reserves of 28.7Moz declared represent a reduction of 2.3Moz, which after accounting for depletion of 1.6Moz due to mining activities in 2016, equates to a 2% decrease year on year
- The cessation of underground mining at Cooke 4, resulted in the exclusion of 2.1Moz Gold Mineral Resources and 0.5Moz Gold Mineral Reserves
- Uranium Mineral Reserves decreased negligibly to 113.2Mlb, with the exclusion of 2.9Mlb from the Cooke Operations offset by additional Mineral Reserves from the Beisa Project being declared
- Total Gold Mineral Resources increased by 3% to 102.0Moz
- Maiden 4E PGM Mineral Resources of 126.5Moz and Reserves of 23. 2Moz declared, position Sibanye in the top 5 PGM companies globally, based on these measures.
- The 12.5Moz decrease in 4E PGM Mineral Reserves year-on year, is primarily due to:
- Mining Depletion (1.7Moz)
- the sale of the Everest mine during the reporting period (1.1Moz)
- duplication of reported reserves of 2.4Moz declared by Anglo American Platinum at the Rustenburg operations in relation to the Kroondal PSA area and
- the application of more conservative commodity price assumptions used by Sibanye relative to those previously used by Anglo American Platinum and Aquarius Platinum ((resulting in a reduction of 6.2Moz at Rustenburg and 0.9Moz at Kroondals Marikana operation). In line with Sibanye reporting standards, assumed commodity prices assumptions for estimating Mineral Resource and Reserves are based on three year average, trailing and spot commodity prices

3 Cooke Inferred Mineral Resources BI refers to material within the Cooke 4 Shaft Prospecting Right (Zuurbekom)

Key aspects that impacted on the 31 December 2016 Statement of Gold and Uranium Mineral Reserves include:
- Following the cessation of underground mining at Cooke 4, 0.5Moz was excluded from Gold Mineral Reserves
- A focused exploration program on secondary reefs resulted in additional Mineral Reserves of 0.6Moz at Kloof (Middelvlei Reef and Kloof Reef at Main shaft), Driefontein (Middelvlei Reef at 8 Shaft), and the Kimberley Reef at the Cooke Operations.
- The continuing review and investigation of previously unmined areas with economic potential (white areas) resulted in a 0.9Moz increase in Gold Reserves during 2016. This was derived primarily at Beatrix West, Driefontein 8 Shaft and Kloof Main Shaft.
- Ongoing exploration at the western extension at Driefontein 5 Shaft, delineated a lower grade, overbank geological facies. This information underpinned an updated geological model, and this geological anomaly has resulted in a decrease in Mineral Reserves of 0.6Moz. Drilling on the opposite site of the overbank provides assurance that the extent of the overbank facies is constrained.
- Minor decreases in grade as a result of additional geological information at Beatrix South and the exclusion of certain high grade pillars at Kloof Main Shaft resulted in reserve decreases of 0.4Moz and 0.3Moz at those operations respectively.
- Uranium Mineral Reserves decreased negligibly to 113.2Mlb, with the exclusion of 2.9Mlb from the Cooke Operations alleviated by additional Reserves from the Beisa Project.

Mineral Resources were declared at a premium of 10% over the Mineral Reserve metal price

1. Kroondal year on year change includes the sale of Everest Mine during the reporting period and the removal of sub-economic Reserves from the Marikana section. Kroondal is mined under a Pool and Share agreement (PSA) with Anglo American Platinum (AAP) and mineral resources and reserves are reported as 50% attributable.
2. .Mimosas change YoY is associated with depletions. Mimosa (Zimbabwe) is a non RSA operation managed as a standalone company in Zimbabwe, 50% attributable to Sibanye. The Reserves reported are June 2016 declared by Mimosa less depletions to December 2016
3. Kroondal is mined under a Pool and Share agreement (PSA) with AAP. Kroondal retains exclusive mining rights for the Kroondal Extension and 1.130Moz 4E PGM (50% attributable) is included in the Sibanye statement ending 31 December 2016.

Key aspects that impacted on the 31 December 2016 Statement of the 4E PGM Mineral Resources and Reserves include:

- At the Kroondal operations total 4E PGM Mineral Reserves decreased by 2.7Moz. This reduction can be primarily attributed to:
o 0.4Moz due to mining depletion between June 2015 and December 2016. To align with Sibanye reporting processes, this reserve declaration considers 18 months of mining depletion.
o A 0.9Moz reduction in Mineral Reserves at Marikana. The Marikana operation was placed on care and maintenance by Aquarius Platinum during 2015 and did not contribute to the 2015 Life of mine plans. These Reserves have been reassessed and are not considered to be economically viable under Sibanyes economic assumptions.
o 1.1Moz associated with the sale of Everest South during the reporting period.
o The balance of the decrease was made up of technical and modifying factors that accounted for approximately 0.3Moz
o At the Rustenburg Operations total 4E PGM Mineral Reserves decreased by 9.4Moz year-on-year. This reduction can be attributed to:
- 1.0Moz depletion due to mining activities during 2016.
- Anglo American Platinum declared the ounces contained in Mineral Reserves at the Kroondal PSA Extension area, amounting to 2.4Mozs, as 100% attributable to the Rustenburg operations in 2015. Aquarius Platinum declared 50% attributable reserves over the same area in 2015. Sibanye has reported these reserves as 50% attributable to the Kroondal operations from where these reserves will be extracted, thus reducing the Rustenburg declared reserves by 2.4Mozs.
- The application of Sibanyes more conservative economic assumptions at Rustenburg resulted in several areas at Siphumulele, Thembelani and Khusuleka shafts, containing approximately 6.2Moz, being considered either uneconomic, or unable to generate sufficient returns from the capital expenditure required to access these reserves, to meet internal project hurdle rates.
- A sensitivity analysis has indicated that at sustained metal price increases of between 5% and 10%, the majority of these resources could be converted back to mineral reserves.
- The 4E PGM Mineral Reserves at Mimosa, a non-managed independent company in which Sibanye holds a 50% stake, are reported as at June 2016, less depletions to December 2016. A revision in the LoM Plan i will be updated by June 2017.
- Mineral Resources at the Hoogland and Hoedspruit projects (6.4Mozs) have not been declared in 2016 as these projects have been discontinued by Sibanye.


Abridged review per operation

BEATRIX
Beatrix is a low-cost, high productivity asset with a life of mine (LoM) extending to 2035. The Mineral Resources include 12.8Moz gold and 27.0Mlb uranium. Gold Mineral Reserves decreased by 5% net of production depletion of 0.3Moz to 3.8Moz in 2016, primarily as a result of lower grades affecting the tail end of the production profile at Beatrix South and Beatrix West sections.

The underground Reserve grade decreased from 3.5g/t in 2015 to 3.2g/t in 2016, primarily due to the inclusion of additional ground from the lower gold grade Beisa project at Beatrix West (a uranium rich project which is currently in Feasibility Study stage). The additional Uranium Reserves from Beisa resulted in an increase of 4.4Mlb

The underground production is supplemented by processing historic rock dumps, with an estimated gold Mineral Reserve of 0.052Moz at a grade of 0.4g/t.

DRIEFONTEIN
Driefontein is a high-yield, long-term operation with gold Mineral Resources of 17.8Moz, gold Mineral Reserves of 6.9Moz and a LoM that extends to 2036. The Mineral Reserves are based on current operations, as well as the 5 Shaft Depth Extension project which commenced in 2016.
Gold Mineral Reserves decreased by 15% net of production depletion of 0.6Moz year on year. This reduction was primarily due to the intersection of a large geological anomaly (overbank area) at 5 Shaft and the 5 Shaft Depth Extension Project, resulting in a reduction of 0.574Moz and reducing the life of mine by 7 years. As a result of this geological anomaly, the Reserve Grade at 5 Shaft is expected to decrease by 0.5g/t to 6.5g/t, and by 1.3g/t to 6.0g/t at the 5 Shaft Depth Extension project. Despite the decrease in grade, the Depth Extension project is still above the economic hurdle rate of the Group and will continue as planned. Further exploration is being conducted in the area, but drilling on the opposite site of the overbank provides assurance that the extent of the overbank is constrained and that the extent of this lower grade zone is well delineated and should not have any further impact on the Reserves.
Underground production is supplemented by processing of an estimated 0.1Moz of gold Mineral Reserves contained in historic rock dumps. Further exploration of historic rock dumps extended the life of the surface operation by another year.

KLOOF
Kloof is a high-yield long-term operation with a LoM extending to 2034 and gold Mineral Resources of 32.6Moz and gold Mineral Reserves of 6.7Moz. Gold Mineral Reserves increased by 2% net of production depletion year on year, with the underground Reserve grade largely unchanged from 7.5g/t to 7.4g/t. The Mineral Reserves is based on the current operations, as well as the 4 Shaft Depth Extension project which commenced in 2015. The increase in Mineral Reserves is largely due to additional Secondary Reefs (Middelvlei Reef and Kloof Reef) of 0.2Moz, as well as white areas (0.3Moz).
Underground production is supplemented by processing historic rock dumps with an estimated gold Mineral Reserve of 0.2Moz, an increase of 22% from last year.

COOKE
Cooke is a short- to medium-term asset, with gold Mineral Resources of approximately 13.9Moz and gold Mineral Reserves of 0.9Moz. With the cessation of underground mining at the Cooke 4 mine, and closure of the uranium processing circuit at the Ezulwini plant, the gold and uranium Mineral Reserve decreased by 0.5Moz and 2.9Mlbs respectively. With the exclusion of Cooke 4, as well as the inclusion of the expected impact of the Grout Project (which will enable mining of high grade crush pillars at Cooke 1 and 3), the average reserve grade at the Cooke Operations increased from 4.7g/t to 5.2g/t. Underground production is supplemented by processing of historic tailings facilities at Cooke Plant which will be completed by end 2017.

KROONDAL
Kroondal is a low cost asset, with the current LoM estimated to extend to 2032. The operation is mined under a pool and share agreement with Anglo Platinum in which the PSA, of which Sibanye has a 50% stake, has exclusive mining rights to the area. Sibanye, through its Kroondal operations, has the infrastructure and processing facilities to mine and process the ore from this PSA area. The operation has 4E PGM Mineral Resources of approximately 7.356Moz (attributable) and 4E PGM Mineral Reserves of 2.291Moz (attributable). Marikana is a lease area situated east of the Kroondal area and forms a natural extension to the existing mine plan for Kroondal. Marikana is however structurally complex with the propensity for higher geological losses and as such, affects the extraction rates of this orebody. The mine plan is sub economic considering the 4E PGM price deck applied to the 2016 valuation and as such, is removed from reserves. AQPSA, the former owners of Marikana, had already placed this operation on care and maintenance in 2015 owing to the high costs of extracting the ore from this section.

RUSTENBURG OPERATIONS
The Rustenburg Operations are long term assets, with the current estimated LoM extending to 2046. The operations contain 4E PGM Mineral Resources of approximately 87.127Moz and 4E PGM Mineral Reserves of 19.206Moz. The decline in the 4E PGM Mineral Reserves year-on-year, was primarily due to the use of commodity price assumptions in line with Sibanye reporting standards and SEC guidelines. These prices are more conservative and as such resulted in several areas at Siphumulele and Thembelani conventional shafts being considered uneconomical.

MIMOSA
Mimosa is a long-term asset, with the current LoM estimated to extend to 2033. The operation has 4E PGM Mineral Resources of approximately 7.0Moz (attributable to Sibanye) and 4E PGM Mineral Reserves 1.7Moz (attributable to Sibanye). The 4E PGM Mineral Reserves have decreased by 0.3Moz year on year, mainly due to depletion.

Abridged review per project

BURNSTONE
The development of the Burnstone Project commenced in 2015, with the first gold production expected by 2018. With Mineral Reserves of 2.1Moz, the project envisages steady state production of approximately 115,000oz per annum from 2021, with a LoM extending up to 2042.

WEST RAND TAILINGS RETREATMENT PROJECT
The West Rand Tailings Retreatment Project (WRTRP) will process the historical tailings storage facilities of the Driefontein, Kloof and Cooke operations for gold and uranium. The project has an estimated gold and uranium Mineral Reserve of 6.2Moz and 97.2Mlb respectively.
The project, which will utilize current metallurgical capacity as well as a Central Processing Plant and Central Tailings Storage Facility, will have an annual steady state production of ~0.1Moz gold and ~0.9Mlbs uranium. The project life will extend to beyond 2068, and will have the additional benefit of reducing the environmental liability posed by historical tailings.

DE BRON MERRIESPRUIT
Gold Mineral Reserves of 2.1Moz for the De Bron Merriespruit Project are based on the original feasibility study previously conducted by Royal HaskoningDHV in 2013. However, the production design and schedule was modified during 2015 in line with enhanced geological and estimation models, with the extraction plan optimized in line with new cut-off grades.

Corporate governance
Sibanye 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. Guided by a commitment to best practice corporate governance, the statement has been reviewed by each Divisions Technical Services. For the Gold Division, the statement for the operations was independently reviewed by Amec Foster Wheeler (Mineral Resources) and by Mineral Corporation Consultancy Proprietary Ltd (Mineral Reserves), and has been found to be compliant with the relevant codes with no material shortcomings. The Platinum Division for 2016 did not have an external audit due to the acquisition approval process occurring during the year.

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 with the exception of those for Mimosa. 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 Platinum Division statement consists of platinum reported as 4E PGM, which consists of platinum, palladium, rhodium and gold. Individual proportions of the 4E PGM are determined via prill split proportions as determined from the assays.

All financial models used to determine Mineral Reserves are based on current tax regulations at 31 December 2016.

For the Gold Division, the lead competent person designated in terms of the SAMREC Code, with responsibility for the consolidation and reporting of Sibanyes Mineral Resources and Mineral Reserves, and for overall regulatory compliance of these figures, is Gerhard Janse van Vuuren, who gave his consent for the disclosure of the 2016 Mineral Resources and Mineral Reserves Statement. Gerhard [GDE (Mining Eng), MBA, MSCC and B.Tech (MRM)] is registered with SAIMM (706705) and has 29 years experience relative to the type and style of mineral deposit under consideration.

For the Platinum Division, the lead competent person designated in terms of the SAMREC Code, who takes responsibility for the consolidation and reporting of the Divisions Mineral Resources and Mineral Reserves, and for the overall regulatory compliance of these figures, is Andrew Brown, who gave his consent for the disclosure of the 2016 Mineral Resources and Mineral Reserves Statement. Andrew [M.Sc Mining Eng] is registered with SAIMM (705060) and has 32 years experience relative to the type and style of mineral deposit under consideration.

The respective business unit-based Mineral Resource managers, relevant project managers and the respective Mineral Resource management discipline heads, have been designated as competent persons, in terms of the SAMREC Code. These persons take responsibility for the reporting of Mineral Resources and Mineral Reserves for their respective area(s). Additional information regarding these personnel, as well as the teams involved with the compilation of the Mineral Resource and Mineral Reserve declaration, is incorporated in the Mineral Resources and Mineral Reserves Supplement that has been published in conjunction with this Sibanye Integrated Annual Report 2016.
