RARE EARTHS - OVERVIEW

16 Rare earth elements (REEs), 15 within the chemical group called Lanthanides Two distinct categories based on atomic weight:

Light Rare Earths (LREEs) Heavy Rare Earths (HREEs)

Distribution of elements vary from deposit to deposit Distribution of elements vary from

• deposit. Most have no substitutes and are

indispensable in many applications China currently accounts for circa 90% of production of rare earth minerals, although it has only about 30% of the deposits of rare earths in the Earth's crust

Periodic Table of the Elements

Rare Earths underpin the “green” tech economy:

Hybrid motors and Battery Technology Consumer Electronics Transportation Aerospace and Defense Energy Efficiency Wind and Solar Power

RARE EARTHS – USAGE BY APPLICATION

5

Rare earth consumption divided into traditional and new material applications

Traditional – metallurgy, machinery, petroleum, chemicals, glass, ceramics, agriculture, light industry and textiles New material - permanent magnet materials, luminescent materials, polishing materials and hydrogen storage materials.

Usage in new material applications has driven the growth in consumption of rare earths

Magnetic Materials, 61.3% Luminescent Materials 6.3% Polishing Materials4.5% Hydrogen Storage Materials 4.1% Other New Materials 3.7% Metallurgy Machinery 7.2% Petroleum / Chemical Industry 4.8% Glass / Ceramics 4.7% Agriculture / Light Industry / Textile, 3.5%

Demand for rare earths from new material applications in 2015 is estimated to account for ~80% of the total demand, of which magnetic materials will comprise the largest component, estimated over 61%

The rare earths for which there is likely to be the greatest demand growth and potential shortage, and which are of the greatest importance for a technologically advanced, clean energy economy, are the so called “Critical Rare Earth Oxides” (“CREOs”) - Neodymium, Europium, Terbium, Dysprosium and Yttrium The importance of rare earths, and CREOs in particular, has been highlighted by both the US Government and the European Commission and security of supply of these scarce commodities is now a strategic imperative for many countries and corporations Demand for CREOs is forecast to double over next 7 years and supply shortages are therefore very likely This growing demand and rising political tensions in many areas of the world are forcing Governments to take decisive action to ensure security of critical raw material supplies over the long term.

ANOTHER RARE EARTH SUPPLY CRISIS IS COMING

Rare earth demand will continue to grow Magnet based applications forecast to grow at highest rate (c. 10%+ per annum), which implies a doubling in demand for magnet REOs over the next 7 years China domestic production may be insufficient to satisfy domestic demand by 2020 unless there is a major increase in production Molycorp (US) and Lynas (Australia) may not survive in their current form. Molycorp is expected to declare bankruptcy in Q3 2015 with debt of more than $1.6bn.

Significant improvements made by Frontier to the proven monazite sulphuric acid cracking process principally through Outotec (Frankfurt) - fluidized bed roasters to replace kilns Eirich – high shear mixers for acid contacting Process improvements eliminate major operational problems of the conventional acid cracking process Produces dry, free flowing feed instead of wet paste Eliminates acid condensation, which prevents corrosion Allows 80% recovery of sulphur (typically zero recovery e.g. Lynas, Molycorp) Allows approx. 99% stabilisation of impurities, resulting in lower impurity removal costs Reduces residence time from circa.1 hour to circa.10 minutes Operational stability and significantly improved process control Lower operating cost

Process improvements substantially eliminate the need for beneficiation before cracking in addition to benefits achieved by the manganese pre-leach

PROPOSED METALLURGICAL FLOWSHEET

Uses rotary kilns, which results in: Poor temperature and residence time control, resulting in inefficient cracking Corrosion in areas where temperature is below acid dew point Material build up and blockage Inefficient heat transfer Limited/no heat recovery No sulphur recovery

CONVENTIONAL ACID CRACKING PROCESS

33

Does not use kilns but uses fluidised bed reactors, which results in More precise temperature and residence time control for effective cracking No corrosion, as temperature maintained above acid dew point No material build up or blockage Very efficient heat transfer

• Approx. 80% lower residence time
• Approx. 50% heat recovery
• Approx. 80% sulphur recovery

PREFEASIBILITY STUDY CONCLUSIONS AND HIGHLIGHTS

All of the specialist PFS studies were reviewed by Venmyn Deloitte, a wholly owned subsidiary of Deloitte (www.deloitte.com), specialising in the technical and economic evaluation of mineral projects. It is concluded that: the studies undertaken comprehensively examined at a PFS level of accuracy all the necessary significant components of the Zandkopsdrift Project the capital and operating cost and price estimates are conservative the overall PFS can be considered to be an ‘advanced study’ of sufficient accuracy and confidence level that potential investors can make reasonable decisions based on the outcomes of the study A technically feasible and economically robust open pit mining and beneficiation operation can be undertaken at Zandkopsdrift at production capacity of 8,000tpa TREO for four years and thereafter, up to 16,000tpa TREO for a total life of mine of 45.5 years, together with the production and sale of a feed grade manganese sulphate by-product. Environmental authorisation and mine permitting are well advanced and no significant environmental

• r legal permitting issues or risks were identified that cannot be managed or mitigated.

The required infrastructure in terms of power and water both to the Zandkopsdrift Mine and the Saldanha Separation Plant can be adequately provided With net opex projected at $11.9/kg separated TREO ( excl. contingency) Frontier wiould be amongst the lowest cost, highest margin producers of high purity, separated rare earth oxides outside China Frontier also likely to be amongst the lowest cost producers of manganese sulphate globally as feedstock is ,in effect, free

KORES acquired a 10% interest in Zandkopsdrift for $23.8m in Dec 2012. Kores has no shareholding in Frontier. KORES pays 10% of capital and operating costs and will purchase 10% of rare earth production at open market prices

Frontier has an interest in two graphite deposits in Mozambique the most advance is the Lurio Project which is located near Pemba Geological mapping, ground geophysical surveys, sampling, trenching, metallurgical test work and conceptual engineering studies were undertaken in 2014 The results of the 2014 program confirmed the presence of high grade, large flake graphite mineralisation, identified the potential for the production of a high purity large flake graphite concentrate and indicated that the project had sufficient economic potential for further work to be undertaken The grade of samples taken in the Lurio project area ranges from 5% to 15% total graphitic carbon although the representivity of the material analysed has yet to be verified. Initial bench scale metallurgical test results indicate that the graphite can be easily liberated, with approximately 60% of the flake being classified as +80 Mesh Frontier is commencing resource drilling on the property with the intention of doing sufficient drilling in 2015 to allow for the definition of a maiden graphite resource

SOUTH AFRICA – IN BRIEF

71

South Africa welcomes foreign investment and virtually all business activities are open to foreign investors. Foreign investors are generally treated the same as local South African investors. The South African Government exercises control over the transfer of money into and out of the country and a foreign investor must obtain permission to transfer money, however the process is very routine. The Government has developed five industrial development zones (‘IDZ’) in South Africa (including at Saldanha Bay) which offers several advantages and incentives for companies locating there.

SOUTH AFRICAN INVESTMENT CLIMATE

The Saldanha Bay IDZ, where Frontier proposes to construct a rare earth separation facility was launched in Oct 2013 "Our strategy [at Saldanha] is aimed at strengthening the maritime support capacity to create economic opportunities from the gas and oil mining activities along the African west coast, as well as the expansion of iron ore mining production and beneficiation in the Northern Cape.“ Jacob Zuma – President of South Africa

All mineral rights in South Africa are held by the State Applications may be made to the Department of Mineral Resources (“DMR”) for a reconnaissance permit, prospecting right and mining right The DMR applies a “first in line” approach to the processing of applications Prospecting rights may be granted for an initial period of 5 years and renewed for an additional 3 years. The holder of a prospecting right has the right to apply for a mining right which may be granted for a maximum period of 30 years. Mining rights can be renewed for up to a further 30 years The holder of a mining right is entitled to enter land, build, construct and lay down infrastructure which may be required for mining, to mine, use water, drill boreholes and any

• ther activity related to mining and processing

Prospecting and mining rights can be transferred with the consent of the Minister (DMR)

SOUTH AFRICA – MINING AND MINERALS

SOUTH AFRICA – ENVIRONMENTAL LAW

The right to an environment that is not harmful to one’s health or well-being is set out as a fundamental right in the South African constitution The environmental right in the Constitution is supported by other environmental legislation that aims to protect the environment while pursuing sustainable economic growth on terms applicable to a developing nation There is no integrated environmental permitting system in South Africa.  It is the responsibility of the project developer to determine which environmental permits are necessary and to ensure that all such permits are obtained. Separate permits are often required from separate environmental authorities and from different levels of government. Regulatory Regime for Water  The use of any water source requires the consent of the authorities. Permission to use water for large developments is granted in the form of a water use licence Regulatory Regime for Air Pollution  Air pollution is regulated by the National Environmental Management Air Quality Act  The Act provides that no person may, without a provisional atmospheric emission licence or an atmospheric emission licence, conduct an activity listed on the national list  With regard to polluters’ liabilities to pay compensation for air pollution, the internationally accepted principle that “the polluter pays” applies and along with any common law remedies that a party may have, a party may be able to claim compensation from a polluter

73

SOUTH AFRICA – ENVIRONMENTAL LAW

Environmental Impact Assessments (EIA)  Legislation provides that certain listed activities cannot be initiated unless an EIA or basic assessment (depending on the size and nature of the activity) is carried out and approval obtained from the relevant authority  If the activity is a listed activity under EIA regulations, then a permit is required before the activity can begin. Other permits from authorities may also be required as there is no integrated permitting system Regulatory Regime for Waste  The National Environmental Management: Waste Act provides for national standards for the storage, collection, transportation, treatment, disposal, re-use and recycling of waste in general as well as hazardous waste  The Act provides that no person may commence, undertake or conduct a waste management activity without a waste management licence if that activity is listed as an activity for which a waste management licence is required

74

SOUTH AFRICA – TAXATION

Standard corporation tax rate is 28% however accelerated capital allowances are available for mining companies allowing all capital costs to be offset against profits immediately There is a royalty payable by mining companies based on the value of the first sale of the product. For Frontier this will be the sale of a Mixed Rare Earth product before separation. The royalty is from 0.5% to 7% of sales depending on Gross Profit margins. Due to capital allowances Frontier is unlikely to any significant royalties for a number of years after production commences Personal income tax ranges from 25% - 40% Value Added Tax (VAT) is 14% Capital Gains Tax is 18.6% but non-residents are not liable for this tax South Africa has double tax agreements with more than 60 countries.
