Lithium Supply
16
• Lithium is abundant globally but tends to be deposited in low concentrations
• Lithium supply currently produced from brine deposits or traditional hard rock deposits
• Key challenge is finding high enough concentrations to make it cost efficient to produce
• Most of known supply comes from Latin America, Australia and China
• Supply currently oligopolistic in structure: three countries (Chile, Australia, China) account for
~85%, and four companies (Talison, SQM, Albemarle, Livent) control most output
• Brine assets are in Latin America, hard rock predominantly Australia while China has both
• New supply challenges
• Construction challenges are hindering the rate of new supply entering the market
• Technical challenges and capacity constraints involved with processing and producing a high
quality battery grade product are dampening supply forecasts
• Battery grade produced in two forms – lithium carbonate and lithium hydroxide
• Brines first produce a lithium carbonate, with further processing required for lithium hydroxide
• Hard rock spodumene deposits produce a concentrate followed by a conversion to hydroxide

Battery Materials Makeup
17
• The value of a project’s revenue stream is tied to its final lithium product
• End product specifications differ by application, but most contaminants must be reduced below
certain limits to achieve a material that is considered battery grade
• +99.5% considered battery grade, <99.5% considered technical grade
• Value also impacted by impurities and buyers’ needs (product technical specifications)
• Technical-grade lithium carbonate is cheaper to produce but rarely meets specifications required
for battery manufacturers (rather tends to be used for industrial applications)
Source: August 2018 article What is Lithium Carbonate by A. Kay and Benchmark Minerals January 2019 article
(https://www.benchmarkminerals.com/lithium-supply-revisited/)
• Lithium carbonate and lithium hydroxide
both have a future cathode requirements
• Both are needed for different variations of
battery cells that are currently commercialized
or near-term commercial
• Lithium metal is needed for solid state batteries
(no commercial applications are viable at scale
yet)

Brine Deposit Overview
18
• Lithium brine deposits currently represent ~66% of global lithium resources
• Form in salars (salt lakes), basins where water has leached lithium from the volcanic rocks
• Lithium is extracted by pumping the brines into a series of evaporation ponds, crystallizing the
other salts out of the brine, leaving a lithium-rich liquor (~18-month process)
• Further processing is required to remove impurities prior to conversion into a lithium carbonate
(Li2CO3) which contains ~19% lithium. Further conversion to a higher-grade hydroxide is possible,
although the process can be expensive

Brine Deposit Overview (Cont’d)
19
• Found primarily in the salt flats of Chile, Argentina, Bolivia, China and Tibet
• The “Lithium Triangle” in Latin America holds ~70% of global reserves and is a major industrial
producer of lithium
• Brine deposits have been the dominant source of production due to lower costs
• Typically easier to explore, shorter timeline to production, and require less upfront capital
(although longer working capital cycles)

Hard Rock Deposit Overview
20
• Lithium hard rock deposits are primarily spodumene deposits
• Most lithium hard rock minerals are found in pegmatites of which spodumene is the most prevalent
• Most spodumene projects today produce a spodumene concentrate of at least 6% Li2O via crushing,
milling and flotation/gravity concentration
• The spodumene concentrate is then sold to a conversion plant and processed, primarily in China. A
concentrate below 6% results in a steep discount on pricing
• Conversion then involves crushing and heating of the concentrate at ~1050C with soda ash
(calcination step). Post calcination, the product is quenched in a sulfate solution (sulfuric acid), then
precipitated as a high purity lithium hydroxide/carbonate
• Approximately 7-8 tonnes of 6% concentrate are required to convert to 1 tonne of lithium carbonate
or hydroxide. The conversion process adds approximately $2,000/t to the total cost of battery grade
product and the remaining is profit to the converter
• Other hard rock lithium deposits exist today
• ‘Soft rock’ – clay deposits existing primarily in Nevada and Northern Mexico, lithium chemical
product (not a concentrate)
• Tuff – volcanic rock, similar to the primary source material for liquid brines prior to water leaching,
lithium chemical product (not a concentrate)
• Other – lithium-boron deposits, tend to be lower grade lithium, relying on boron revenue

Equal: Hard Rock (Pegmatites) vs. Lithium Brine by N. LePan
• Australia is the largest global producer of spodumene concentrate
• Hard rock deposits are less dependent on a changing climate/environmental factors for production
when compared to brine assets
• Cost of producing lithium hydroxide is competitive versus brine deposits
• Spodumene can be directly transformed into hydroxide while brine deposits must first produce a
carbonate product prior to conversion to hydroxide
• Cost of producing lithium carbonate from spodumene is more expensive than from brines
• Operating cost highly dependent on re-agent consumption and price (sulfuric acid, soda ash)

Brine vs Hard Rock Comparison
22
Brine Deposits:
+ Lower operating costs, quicker timeline to initial production
- Longer ramp-up to full production (evaporation in large ponds in unique climates), expansion
and producing a battery grade product versus technical grade has been challenging
Hard Rock Deposits:
+ Faster processing rate, a more reliable and consistent product
- Getting to production can take longer and be costlier, no value added product (concentrate)
unless fully integrated

Brine Deposits Hard Rock Deposits
ADVANTAGES ✓ Widely accepted, dominant source of production currently
✓ Easier and quicker permitting process
✓ Typically found in flat and arid areas making exploration easier
✓ Decreased environmental impact
✓ Softer rock, less geological complexity
✓ Typically shallower than hard rock mines
✓ Smaller scale requires less capital upfront
✓ Cost of producing lithium carbonate much lower, however needs
additional refining
✓ Reliable and consistent production (“truck and shovel mining”)
✓ Quick processing durations
✓ Geographically dispersed
✓ Less dependent on changing climate for production
✓ Cost of producing lithium hydroxide competitive

DISADVANTAGES  Limited to select climates and regions due to processing
methodology, therefore processing is weather dependent
 Achieving low impurity battery grade (+99.5%) carbonate
requires additional refining
 Longer processing duration (~16 months)
 Smaller scale operations (scalability a challenge)
 Process to convert lithium carbonate to hydroxide expensive
 Significant freshwater requirement for operations
 High progressive royalty rates (Chile, Argentina)
 Longer timeline from first discovery to production
 Deposit style tends to lend itself to higher mining costs later in
the life of mine
 Typically higher upfront capital cost requirement
 Higher cost to produce lithium carbonate than brines
 Challenges with achieving modelled recoveries
 Significant pricing differential dependent on product
 ~40% of value chain not retained by concentrate only producers

Trends & Observations
24
• Spodumene Vertical Integration:
Spodumene projects are realizing the need to become fully integrated to capture 100% of the value
chain. However, capital costs may be a limiting factor.
• Limitations on Brine Expansion & Quality:
Brine projects are experiencing the challenges of expanding production, and achieving battery grade
carbonate without further, and costly, refining.
• Lithium Carbonate and Lithium Hydroxide both have a place:
Lithium hydroxide may be the faster growing segment as its much smaller today, but lithium carbonate
will remain strong. Both chemicals have a strong role in the foreseeable future.
• Strategic Assets Can Scale:
Assets with characteristics that can readily scale production are desirable. The “lens” the supply chain is
looking through now is projects with potential to expand to 50,000 tpa LCE and then to 100,000 tpa LCE.
• Impurity Reduction to ppb:
The trend to lower and lower impurity levels is critical to better batteries (safety and efficiency). Projects
that can produce a low impurity product are optimal as it requires less refining before being suitable.
