Key Applications of REE:Magnets for Electric Motors

REE (NdFeB) or “Neo” Magnets reduce electric motor/generator size and weight, and improve efficiencyMajor applications include:

Electronics (grams)Hybrid-electric cars (1-2 kg)Industrial air conditioners (500 kg)Wind turbines (0.6-1.0 tonne/MW)MRI machines (1-3 tonnes)

Trend toward larger volume applicationsREE magnets can reduce power consumption by 50% Approximately 30% of the magnet is Neodymium metal

HREE dysprosium and terbium additions are key to making “heat resistant” magnets vital to automotive and other applicationsHREE phosphors key to energy efficient lighting, display screens

Environmental Concerns: Uranium & Thorium

All Rare earth deposits contain some Uranium (U) and Thorium (Th) but there are no other hazardous materials in the ore.

Nechalacho U & Th content is exceptionally low averaging 23ppm U (background levels) and 114ppm Th (mildly elevated) in high grade ore

Levels are safe for mining and processing activities and no water issues due to insolubility

Th is concentrated with the rare earths and does not go to mine tailings

Levels do not invoke additional permitting requirements from Canadian Nuclear Safety Commission or special transport regulations

Proposed Hydromet facility is on a brownfields mining site and will use historic open pits for waste disposal. Th will be diluted to safe levels

Rare Metals: Key Enablers of Clean Technology

Rare earth elements (“REE”) such as Neodymium, Terbium and Dysprosium; & other rare metals such as Lithium, Gallium, Indium (+Tin), Niobium, Tantalum, Zirconium

Creating new materials such as thin films (solar) and high strength magnets, the key to energy-efficient electric motorsRenewable energy: solar power, wind turbines, nuclear powerLED lighting, rechargeable batteries, light weight aerospace alloysHybrid and electric cars (30 kg REE in aggregate)

38

Key Facts About Rare Earth Elements or “REE” … 1

Widely dispersed, but rarely concentrated; only found as a group, often with uranium & thorium. Deposits are not rare.

Typically concentrated in alkaline intrusive rocks (carbonatites) or peralkaline granites (Thor Lake)

Many different ore minerals: bastnaesite, allanite, monazite. xenotime, eudialyte, fergusonite, zircon

In most deposits, light rare earths “LREE” are far more abundant than heavy rare earths “HREE”; LREE typically comprise 98-99% of resource...HREE far more valuable

REE must be recovered as a group and sequentially separated; HREE cannot be selectively extracted

39

China Dominates Global REE Production

China currently produces over 95% of global REE supplyChina now imposing export quotas and tariffs on REE New non-Chinese supply sources needed to maintain balanceSupplies of key HREE from China (Y, Dy, Tb) will remain tight with potential for a complete export banJapan totally reliant on China for supplies

REE supplies in China are tightening and Chinese companies are actively trying to acquire additional REE resources around the world.

Niobium Production

Giant Araxa deposit in Brazil (CBMM) produces 80% of world supply (150,000 tpy Nb2O5)

Nechalacho is now the 3rd largest deposit in the world and will produce 1,700 tpa Nb2O5 as by-product

Demand increasing for main use in High strength low alloy (HSLA) steels as use of HSLA steels is expected to double in next few years

Traditional markets in architecture, ships, bridges.

Increasing use in automotive... Reduces the weight of the vehicle and improves fuel efficiency.

$9 of Nb = 100kg less weight = 1 litre of fuel savings per 100km

47

Zirconium Production

Primary zirconium production mainly from zircon sands in Australia and South Africa (1.5 million tpa zircon)

China imports zircon sands and is the only global producer of Zirconium Oxychloride (ZoC) the basic chemical feedstock for producing Zr metal and other chemicals

China increasing ZoC consumption, applying export taxes

Zr Metal critical for nuclear reactors as fuel cladding

Many emerging uses:Hemodialysis treatment (zirconium phosphate)Solid Oxide Fuel Cells (yttrium stabilized zirconia)

48

Zirconium Use in Dialysis

Zirconium Phosphate can be used for home dialysis treatment.

The benefits of home dialysis:No time-consuming trips to hospitalMore frequent treatments possible, to mimic natural kidney function.More mobility possible for patientsLess costly for government

Individual consumption of ZrO2 equivalent is 1lb per treatment, with 3 treatments per week or potential demand of 7,000 tonnes per year ZrO2 to treat 100,000 patients

Nechalacho will produce 18,000 tpy ZrO2

Key Application of REE Magnets in Wind Turbines

New GE 4 MW wind turbine uses a 90-ton generator with 2-3 tons of NdFeB permanent magnets to eliminate the need for a gearbox, reducing breakage and energy loss

Permanent magnet generator (PMGs) make the whole assembly (nacelle) lighter weight allowing higher tower

Already planning to build 10 MW size turbines

Underground Mine (2,000 tpd)

Much smaller environmental footprint than open pit with less waste rock removal and less disturbance of water courses

Tailings will be used for paste back-fill, waste rock for construction

Tailings Disposal Facility

Environmental Impacts

Tailings benign consisting largely of common rock forming minerals quartz feldspar, mica and magnetite (no sulphides)Natural basin identified containing

two small ponds with no fish habitatIdeal drainage and discharge

design, inert water chemistry

RESTART Act introduced into U.S. House of Representatives

Expedite the permitting process in order to increase the exploration and development of domestic REE sources,

Setting up a Defense Logistics Agency (DLA) REE inventory --where DLA enters into long-term supply contracts and then makes the supplies available for purchase to federal government contractors -- to generate a domestic market and facilitate the domestic sourcing of rare earth alloys and magnets;

Making government-backed loans available to start REE production should lending from capital markets not be available;

Requiring cabinet Secretaries to appoint REE Executive Agents

Establishing a REE program at the U.S. Geological Survey
