Sibanye-Stillwater enters into strategic exploration partnership to unlock value
at its Altar project

Johannesburg, 29 June 2018. Sibanye-Stillwater (Tickers JSE: SGL and NYSE: SBGL) is
pleased to advise that it has entered into an arrangement agreement (the
“Arrangement Agreement”) with Regulus Resources Inc. (“Regulus”) and a newly
formed subsidiary of Regulus, Aldebaran Resources Inc. (“Aldebaran”), creating a
strategic partnership in order to unlock value at its Altar copper-gold project in
San Juan Province, Argentina (“Altar” or the “Altar Project”).

Transaction overview
Under the terms of the Arrangement Agreement, Stillwater Canada LLC, an indirect,
wholly-owned subsidiary of Sibanye-Stillwater (“Stillwater Canada”), will enter
into an option and joint venture agreement (the “JV Agreement”) with Aldebaran,
whereby Aldebaran will have the option to earn into a maximum 80% interest in a
wholly-owned subsidiary of Stillwater Canada, Peregrine Metals Ltd. (“Peregrine”),
which owns the Altar Project.     Concurrently, Regulus will also spin-out its Rio
Grande copper-gold project and other early-stage Argentine mining assets to
Aldebaran,   including  the   drill-ready   Aguas  Calientes  gold-silver  project
(collectively referred to as the “Arrangement”).     Aldebaran has entered into a
subscription agreement with Route One Investment Company LLC and certain related
investment funds (“Route One”) of San Francisco, whereby Route One has committed
to provide initial financing of at least US$30 million to Aldebaran.

Rationale for Sibanye-Stillwater
The consideration to Sibanye-Stillwater, for Aldebaran’s option to acquire up to
an 80% interest in the Altar Project, comprises:

-   An upfront cash payment of US$15 million to Sibanye-Stillwater upon closing of
    the Arrangement
-   19.9% of the shares of Aldebaran, subject to proration if the initial financing
    exceeds US$30 million (up to a maximum of US$40 million)
-   A commitment from Aldebaran to carry the next US$30 million of spend at the
    Altar Project over a maximum of five years (inclusive of 2018 drilling that was
    conducted between February and May of this year) as an initial earn-in of a 60%
    interest in the Altar Project (the “Initial Earn-in”)

Pursuant to the Arrangement, Aldebaran may also elect to earn into an additional
20% interest in the Altar Project by spending an additional US$25 million over a
three-year period following the Initial Earn-in.

The Arrangement sees Sibanye-Stillwater benefit from upfront proceeds (US$15
million), while retaining a direct interest in the project of either 40% or 20%
(should Aldebaran exercise its additional earn in option) as well as an indirect
exposure though its 19.9% shareholding in Aldebaran. In addition, through its
shareholding in Aldebaran, Sibanye-Stillwater will have indirect exposure to the
Argentine exploration assets that Aldebaran will be acquiring from Regulus as part
of the Arrangement, including the Rio Grande and Aguas Calientes projects, amongst
others.
This Arrangement creates a new, well-capitalised, Argentinean focused exploration
company, Aldebaran, which expects to benefit from the synergies derived from
exploring a multi project portfolio.     Aldebaran will be led by an experienced
management team, who have a track record of creating value in South American
projects through advancing these projects up the value curve. The Arrangement is
subject to customary conditions for a transaction of this nature.

Sibanye-Stillwater CEO, Neal Froneman commented: “This transaction is consistent
with our strategy of maintaining our focus and investment on our core mining
operations. We believe Aldebaran possesses the vision, skills and experience to
unlock the considerable upside potential of the Altar Project, in which, we will
continue to hold a meaningful interest.    Consistent with our vision, we believe
this partnership with Aldebaran will deliver value for all stakeholders, as the
Altar Project is progressed up the value curve”.

John Black, CEO and a Director of Regulus, stated: “The proposed transaction
creates a new, well-financed company to realize value on our Argentine assets and
participate in another major copper-gold project. The Altar Project already has a
very large 43-101 copper-gold resource and we see the potential to materially
enhance the value of the project through further discovery and delineation of
higher-grade zones. The agreement with Sibanye-Stillwater is designed to provide
immediate benefits to shareholders of both companies, as well as exposure to
significant future upside potential from an attractive portfolio of exploration
projects.”


Future Aldebaran project portfolio

The Altar Cu-Au Porphyry Project is a copper-gold property in San Juan province,
Argentina. It is located in the Andes Mountains, approximately 10km from the
Argentina-Chile border, and approximately 180km west of the city of San Juan. As
at 31 December 2017, Altar contained 2,057 million tonnes of measured and
indicated resources at 0.3% copper and 0.1 g/t gold (14.5 billion pounds of copper
and 5.2 million ounces of gold) and 557 million tonnes of inferred resources at
0.3% copper and 0.1 g/t gold (3.4 billion pounds of copper and 1.1 million ounces
of gold). Further information pertaining to the Altar resource can be found on the
Company’s   website  (https://www.sibanyestillwater.com).       Sibanye-Stillwater
obtained ownership of the Altar project as part of the acquisition of Stillwater
Mining Company, however considering the greenfields nature of the project, it is
not deemed core to the Sibanye-Stillwater’s strategy of focusing on its producing
assets.

The Rio Grande Cu-Au-Ag-Mo Porphyry Project is located in Salta Province in north
western Argentina, located along the prominent NW-trending Archibarca Lineament
which also controls the location of the world-class Escondida porphyry Cu deposit
(BHP-Billiton). The Rio Grande deposit is located approximately 80 km due south of
the large Taca Taca porphyry Cu-Mo deposit (First Quantum Minerals) and
approximately 10 km west of the Lindero Au porphyry deposit (Fortuna Silver). An
initial NI 43-101 resource estimate was prepared in 2011 on the basis of 78 drill
holes (33,015.47 m) and 11,294 m of surface trenches and includes all drilling on
the project through to the end of 2008 (Wardrop NI43-101 report of January 19,
2012). The estimated mineral resource at Rio Grande includes 55.3 million tonnes
of indicated resource at a grade of 0.36 g/t Au and 0.34% Cu (0.64 million oz
contained Au and 0.4 billion lbs contained copper) and an inferred resource of
101.1 million tonnes at a grade of 0.31 g/t Au and 0.30% Cu (1.00 million oz
contained Au and 0.7 billion lbs contained copper). Regulus completed further
extensive additional drilling in 2011 and 2012 at Rio Grande (39,995 m in 48 drill
holes) and a short drilling program was completed at the nearby Cerro Cori target
in 2013-14 (1,200 m in 4 holes). For further information pertaining to the Rio
Grande      Project     please      refer      to     the      Regulus website
(https://www.regulusresources.com/projects/rio-grande-argentina).


The Aguas Calientes Project is located in north western Argentina in Jujuy
Province. Aguas Calientes hosts epithermal precious metals mineralization. The
project has had limited previous drilling (2,818 m in 20 drill holes by previous
operators) but based on exploration activities undertaken by Regulus,     there is
sufficient potential to continue exploration activities for a potentially
significant target. The project has drill ready targets and has been permitted for
a drill program. For further information pertaining to the Aguas Calientes Project
please           refer          to           the          Regulus          website
(https://www.regulusresources.com/projects/aguas-calientes-argentina).


A complete summary of the significant drill results from the Altar Project,
including drilling in the 2012, 2013, 2016 and 2017 drilling campaigns is
available        on         the        Sibanye-Stillwater       website  at
