The first phase focuses on the extension of existing mine life and development of existing reserves and mineral

inventory

− Batu Hijau Phase 6 pushback has commenced

− Dairi mine expected to commence production and ramp up to 1 million tonnes per annum of production in 2013(1)

− Complete feasibility studies for Gorontalo and Citra Palu

− Development activities in Mauritania

− Exploration in Liberia

The second phase focuses on the exploration and development of existing discoveries

The first immediate priority of BRM management is to focus on core asset development and commercializing its portfolio of mining assets

Newmont Nusa Tenggara

Batu Hijau is a large scale open pit gold and copper

mine located in South-west Sumbawa, Indonesia

BRM currently owns 18%(1) effective interest in Batu

Hijau with the opportunity to acquire a further 7%

through PT Multi Daerah Bersaing in the near-term

One of only three mines in the world with total ore

tonnage in excess of 1 billion tonnes and gold

grades higher than 0.2g/t

Contract of Work signed with Indonesian

Government in 1986

One of the lowest cost gold or copper operations in

the world ($ 0.7/ lb copper ; $ 237/ oz gold)

Batu Hijau’s reserve of 7.7bn lbs of copper and

7.6mn oz of gold (Reserve life of 10 years for Gold

and 14 years for Copper based on 2010 production

rate)

Elang copper and gold deposit is estimated to be a

potentially larger resource than Batu Hijau

Elang exploration permit received: 27 Sep 2010 – 28

Feb 2030

Potential to extend Batu Hijau mine life through

conversion of resources

(1) BRM holds 75% of MDB which holds 24% of PT NNT.(2) Merukh Family’s interest effectively controlled by Newmont through loans made by Newmont.(3) Newmont and Sumitomo hold a 56% interest in PTNNT through the Nusa Tenggara

Partnership. Newmont is the operator.

(Province of Gorontalo)

Based on explorations to date, the following have

been identified in the concession:

− Four copper and gold systems

− Three gold, silver and copper systems

− Four gold and silver systems

Currently working on advanced exploration and

feasibility studies for development of the mines

Conducted a scout drilling program in the South of

the COW area in 2008

JORC Resource to be completed by end 2012 with

commissioning expected in 2H 2014

Target large scale porphyry style mine similar to

Batu Hijau

Focus on projects at Cabang Kiri East and Sungai

Mak for porphyry copper and Tulabolo for

epithermal mineralization

Conceptual development model is to build a 25

million tonnes per annum (feed tonnes) copper

concentration plant that would be able to process

0.6% of copper and 0.6 grams per tonne of gold

material

Drivers of Gold Demand

In 2008 and 2009, estimated gold demand from the investment sectorrose significantly, driving a substantial increase in the price of gold overthis period

This trend has continued throughout 2010 with gold prices reachingrecent highs as a result of investors’ fears in the value of currency andthe risks relating to other asset classes
