Johannesburg, 14 November 2017: Sibanye-Stillwater is pleased to advise that a Competent Person’s Report (CPR) on its US PGM mineral assets, located in Montana, United States of America (“US PGM assets”), has been completed by the Mineral Corporation Consultancy (Pty) Limited and is now available on its website: www.sibanyestillwater.com.

The report, with an Effective Date of 31 July 2017, has been compiled in terms of the 2016 edition of the South African Code for the Reporting of Exploration Results, Mineral Resources and Mineral Reserves (the “SAMREC Code”)and the 2016 edition of the South African Code for the Reporting of Mineral Asset Valuation (the “SAMVAL Code”).

A PGM Mineral Resource of 80.8 Million 2E ounces at a grade of 16.8g/t has been declared for the first time for the US PGM assets under the SAMREC Code.  The Mineral Resource comprises 49.4 Million 2E ounces at a grade of 16.6g/t in the Inferred category and 31.3 Million 2E ounces at a grade of 17.0g/t in the Measured and Indicated categories.  PGM Mineral Reserves of 22.2 Million 2E ounces at a head grade of 16.3g/t have been declared, a 5% increase from those declared by the Stillwater Mining Company (“Stillwater”) in 2016. Mineral Reserve grades have remained consistent year-on-year, reaffirming the quality of the US PGM assets acquired by Sibanye-Stillwater in May 2017.  Mineral Reserve economic viability testing was based on three year trailing average commodity prices as per the US Securities and Exchange Commission (SEC) guideline. This includes a US$704 palladium price and US$1,047/oz platinum price assumed.  The average 2E prill split at the US PGM operations is 78% palladium to 22% platinum.

The CPR includes a SAMVAL Code compliant Mineral Asset valuation of the US PGM assets.

On the basis of the Income Approach¹, underpinned by a discounted cash flow model, a value of US$2.7 billion (post tax, but pre-financing) has been established for the US PGM assets, (assuming a real discount rate of 5% for the US region), which compares favourably to the US$2.2 billion equity price paid for Stillwater. For valuation purposes, the average real palladium price of US$888/oz from 2018-2021 (thereafter a real long term price of US$850/oz) and an average real platinum price of US$1,133/oz from 2018-2021 (thereafter a real long term price of US$1,150/oz) have been assumed.

Sibanye-Stillwater’s CEO, Neal Froneman commented: “The outcome of the CPR confirms the value accretive nature of the transaction and our decision to purchase Stillwater. It is also exciting to note that there is still further value upside from the very substantial mineral resource base and other non-core assets acquired along with the US PGM assets.”

The CPR has been published as per an undertaking to the JSE Limited which was recorded in the acquisition circular (posted on 20 March 2017), which included an executive summary of The US Competent Person’s Guide 7 Report on Stillwater, compiled in terms of Industry Guide 7 published by the SEC, and not the SAMREC Code.

¹ The SAMVAL Code describes the Income Approach valuation approach as follows: The Income Approach relies on the ‘value-in-use’ principle and requires determination of the present value of future cash flows over the useful life of the Mineral Asset. It provides an indication of value by converting future cash flows to a single current capital value. For the estimation of Market Value, the present value capitalisation shall be generated using a discount rate derived from market conditions. The Income Approach is most often applied to properties in development or production.
