BAUXITE OVERVIEW Bauxite is the main commercial mineral from which aluminium oxide is extracted, which in turn is smelted to form aluminium metal: 5t bauxite (ore) 2t alumina (refinery) 1t aluminium (smelter)  Typically, a bauxite resource contains 30-60% alumina (Al 2 O 3 ), and occurs as two main types: trihydrate ("low temperature") bauxite and monohydrate ("high temperature") bauxite  The aluminium industry is no longer as integrated as it used to be - pricing power is shifting upstream to alumina and bauxite producers  Aluminium demand, however, drives alumina and bauxite growth - medium to long term demand is still strong  Demand continues to grow in key sectors including transportation, construction, power, packaging and consumer products 3

METAL USAGE IS LINKED TO ECONOMIC DEVELOPMENT  Iron ore and copper usage maturing following rapid industrialisation in China and other emerging markets  Aluminium demand in China is still in its early stages with saturation not expected to match current levels of steel or copper for 30 years  As an economy matures, requirements shift from building and infrastructure development to consumer goods, vehicles, transport, infrastructure etc  The urbanisation of China is forecast to shift toward internal consumption which will benefit demand for aluminium. Chinese policy supports this 4

CHINA FUNDAMENTALLY CHANGED THE ALUMINA INDUSTRY  China’s aluminium production up 400% in last 15 years HISTORIC ALUMINA CAPACITY EXPANSIONS (MTPA) 1  China began importing significant amounts of alumina to supply rapidly expanding smelting industry 120  To avoid reliance on imported alumina China began to develop its own domestic alumina refining capacity 100  Since 2002, China has developed over 50Mt of alumina refining capacity 1  Chinese alumina production was based on two 80 approaches: • Development of merchant refining capacity in 60 Shangdong based on imported Indonesian bauxite • Processing of domestic ore 40  New refining capacity has lead to record increase in bauxite demand and imports  20 Declining quality of domestic bauxite in China and diminishing global reserves of high quality ore • Impetus for refiners and smelters to secure a - long term supply of ore 1974 1976 1978 1980 1982 1984 1986 1988 1990 1992 1994 1996 1998 2000 2002 2004 2006 2008 2010 2012 2014 China RoW 1 Source: World Aluminium 5

BEL AIR - MARKET OPPORTUNITY  China is buying low quality material from India and Malaysia at high prices  Malaysia recently banned exports for 3 months but even when exporting is a short term solution  Guinean bauxite is some of the highest quality in the world  There is a significant opportunity for Bel Air to enter the market as a premium quality bauxite  Refineries are prepared to pay a premium for high quality  Material from Brazil, Guyana, Ghana and Guinea can command up to 50% more than the market price BEL AIR BAUXITE  AvAl 2 O 3 : >40%  RxSiO 2 : <2%  AvAl 2 O 3 : RxSiO 2 ratio: >23 6

DFS OVERVIEW EXTENSIVE DFS VALIDATED LOGISTICS, CONSTRUCTION, AND MINING PLANS, AS WELL AS ECONOMIC MODEL  Completion of the DFS has ensured: • Pit to Ocean Going Vessel (OGV) simulation and integration • Optimisation / Value engineering where applicable • ESIA and biodiversity planning and mitigation • Construction readiness • Construction permit applications underway  Control of simple logistics solution • Short haul, causeway conveyors, transhipment barging and onsite infrastructure  Low operating cost following optimisation of mine plan • Minimised strip ratio, limited re-handling and automated materials handling set-up  Minimum 15 years mine life with initial production rate of 5.5 Mtpa  Economically robust under multiple bauxite pricing cases 8

OPERATIONAL SUMMARY  Direct Shipping Ore will be mined from a total of six pits • Minimum of two areas will be in operation at the same time • Increases production flexibility as well as adequate ore blending capability  Open strip mining will use surface miners  Material will then be transported via truck to the ROM tip  Ore will then be stockpiled and handled via conveyor over a rubble causeway and loaded onto barges  Transhipment handled via self-propelled barges and transhipment vessel to OGVs 9

MINING METHOD SURFACE MINING – LOW OPEX, SIMPLE HANDLING, HIGH EFFICIENCY Benefits vs drill and blast:  Sustainable, reduces loss and dilution and no high grading  Single phase – no drilling, explosives, crushing  Significantly reduces strip ratio, waste handling and haulage costs • Minimises footwall waste  Improves in pit ground conditions which enables multi-purpose haul fleet selection  Lower fuel consumption Current surface mining operations  Reduces bulking factor for improved haulage  Paragominas, Brazil efficiencies  Less dust creation  Rusal, Guinea  Iron ore, Western Australia 10

MATERIALS HANDLING PROJECT ADVANTAGED BY PROXIMITY TO COAST AND CONTROL OF DEDICATED LOGISTICS AND FACILITIES Materials handling  Simple, efficient materials handling infrastructure  Automated, low opex approach  Premium on high reliability equipment, eg. apron feeders, telestacker  Inherent redundancy and catch-up ability  De-linking of mining process (continuous) and barge loading (batch process) Process  ROM ore will be delivered to the bin using 40m³ side tipping trucks  This then withdrawn from the ROM bin using two apron feeders (2,000tph design rate) and conveyed to the ore stockpile  Ore reclaimed from stockpile by two apron feeders and conveyed along jetty to barge loader  Chemical dust suppression agent used to minimise environmental impact  SCADA control included 11

ONSHORE INFRASTRUCTURE SELF SUFFICIENT INFRASTRUCTURE WITH RAPID MOBILISATION AND MINIMAL COST  Self contained camp and operations centre will be built at coast  Simple, modular, pre-fabricated package systems  Quality designed to sustain life span of 15 years  Water wellfields already identified and designed • Mine camp area – near Bel Air Hotel • Quarry and Export Facility infrastructure area • MSA and Mining Areas  Self-generating power from high-speed diesel generators  Dedicated communications and internet  Contained sites = improved safety and security 12

MARINE INFRASTRUCTURE TRANSHIPMENT IS THE OPTIMAL METHOD FOR BULK EXPORT Rubble mound causeway  Will provide access from the shore to water depth suitable for a barge load-out berth  Simple geotechnical structure placed on bedrock  Core and armour material will be supplied from quarries owned by Alufer  Scale model being constructed and tested to confirm the design criteria. (Please see Appendix for causeway simulation photos) Block wall retaining structure at loading point  Due to barge selection the berth length is significantly reduced  Lock wall berth structure also preferred as it does not require piling during the construction phase 13
