ESTABLISHMENT CONVENTION





BETWEEN:

The Government of the Republic of Mali, hereinafter designated the State,
represented by the Minister of Mining, Industry and Energy Affairs, Mr KADARI BAMBA,

AND:

The Société des Mines de Loulo, a Limited Liability Company governed under the Law of Mali, with its head office in Bamako, hereinafter
designated Somilo, represented by its shareholders, the Republic of Mali and the Société dEtudes, de Recherches et dExploitations Minières (SEREM).

RECITALS:

Whereas the State and the
Bureau de Recherches Géologiques et Minières, hereinafter BRGM, in an agreement dated 27 December 1978, established a mineral exploration syndicate for prospecting for deposits of gold, copper, tin and diamonds within
the Kenieba and Kagaba exploration permit areas,

Whereas, following the work carried out by the syndicate, the State on the one hand and the
partners in the syndicate on the other, have signed an Establishment Convention, dated 21 March 1983, hereinafter referred to as the 1983 Convention,

Whereas, within the framework of the 1983 Convention, Somilo was established on 20 October 1988, following the discovery of the Loulo gold deposits, between SEREM (a fully owned subsidiary of BRGM)
and the State,

Whereas Somilo is exercising its activities within the framework of the 1983 Convention and the shareholders of Somilo are
bound by a Shareholders Agreement dated 7 November 1987 and by its Codicil dated 20 October 1988,

Whereas the shareholders of
Somilo have, in pursuance of Article 21 of the 1983 Convention, signed an options and share transfer contract with BHP Minerals International Inc., hereinafter designated BHP, this contract being hereinafter referred to as the
Options Contract, providing for the participation of 51 % by BHP in the authorised company capital of Somilo and its participation in the development and mining of the said deposits at Loulo,

Whereas, prior to the signature of the Options Contract, the State had asked the Somilo shareholders to adapt the tax and customs systems under the 1983
Convention, for the mining of the Loulo deposits, to the provisions of the Mining Code promulgated by Order N° 91-065/P-CTSP dated 19 September 1991, on the basis of Annexe 2 to the said Contract,



---

Whereas, furthermore, Article 6 of the Options Contract makes provision for the modification of the 1983
Convention, prior to BHPs participation in Somilo, not only to subject Somilo to the tax and customs provisions of the Mining Code but also to adapt the conditions of the 1983 Convention and, possibly, the Syndicate Agreement and the
Shareholders Agreement, to the conditions laid down by the shareholders of Somilo and BHP for BHPs participation in Somilo.

Consequently, the State and Somilo, in accordance with the provisions of the Mining Code, have expressed their wish to conclude the present Establishment
Convention which will govern development and mining activities of the Loulo deposits and which will replace the 1983 Convention with regard to the said activities of Somilo and which will define the terms and conditions applicable to BHPs
participation in Somilo and in the mining project of the Loulo deposits.

ARTICLE 30 - FORCE MAJEURE



| | 30.1. | Should either of the Parties fail to perform any of its obligations laid down in the present Convention, other than obligations relating to payment or
notification, it shall be excused insofar as this failure to perform the obligation is due to a case of force majeure. If the performance of an obligation affected by force majeure is delayed, the period stipulated for its performance, as well as

| | Convention, shall automatically be extended by a period equal to the delay caused by the occurrence of the case of force majeure. However, it is understood that neither the State, nor Somilo can
invoke in their favour as constituting a case of force majeure, any act or action (or any failure to act) that is a fault on their part.

such as events of war or conditions attributable to war, insurrection, civil strife, blockade, embargo, strikes or other labour related conflicts, riots, epidemics, earthquakes, floods or other bad weather, explosions, fire, lightning, government
actions, acts of terrorism. The intention of the Parties is that the term force majeure shall be interpreted in accordance with the principles and usage of international law.
| | ----- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 30.3. | When either Party considers that it has been prevented from fulfilling any obligation because of a case of force majeure, it shall immediately notify the other Party of
this impediment in writing, and provide reasons. The Parties shall take all measures necessary to ensure that the performance of the obligations affected by this case of force majeure continues as normal as soon as possible, subject to the fact that
neither Party shall be obliged to settle any disputes with third parties, including labour disputes, unless the conditions are acceptable to it or unless the settlement is made compulsory following a final arbitration judgement or a decision by a
competent legal court. The State undertakes to co-operate with Somilo to settle by mutual agreement any labour conflict that may arise.
