Graphite. Lithium. Rare earth elements. What do these metals and minerals have in common? They are playing bigger and more critical roles in widely used big kid toys like smartphones, tablets and electric vehicles. Investors can't stay on top of every hot commodity but Luisa Moreno, mining analyst with Euro Pacific Canada, offers some companies developing graphite, lithium and REE resources for the toys and technology of the future in this interview with The Mining Report.
The Mining Report: What are the key advantages of vein or lump graphite deposits over flake deposits?
Luisa Moreno: Two advantages of vein or lump graphite deposits would be the natural high-grade purity of the graphite in the ground, as well as the relatively low cost of production, most of which comes from Sri Lanka. Another important point is that it is usually sold at a premium price relative to natural flake graphite.
TMR: Are there any advantages flake deposits have over vein deposits?
LM: I think an advantage is that they have more applications. The flake graphite market is much larger. Vein deposits are quite rare and make up less than 1% of the market.
TMR: Flake graphite deposits can be high grade too, can't they?
LM: Flake graphite deposits can be high grade but you won't find deposits grading 90-99% in the ground. Flake deposits tend to run 2-3% graphite. Some deposits in Quebec have 16-20% grade. It seems that there's a correlation between grade and the recovery of larger natural flake.
TMR: Which one should an investor prefer?
LM: To start, investors should look at these graphite companies just as they would look at any other mining company. They need to understand the feasibility of the project-the capital requirements, operating costs, etc. For industrial and critical materials it is also important to understand size of the market, the project time to market, the type of product it will produce and how much it could be sold for.
We talked about flake versus lump graphite deposits, but within the flake type products there are the finer flake, the medium and the larger flake, and it is important to understanding how much of each a mine can produce, as they are sold at different prices. The shape of the flakes and other characteristics also influence the price and applications. In the case of lump graphite, the market is estimated to be ~5,000 tons [5 Kt] per year, but it's relatively rare. If there is a company with a lump or vein graphite deposit that requires low capital and operating costs, has secured an offtake agreement and the project has strong economics, which could potentially be a good investment.
TMR: Where's that 5 Kt coming from now?
LM: It's coming mainly from Sri Lanka. AMG Advanced Metallurgical Group N.V. (OTCPK:AMVMF) is a major producer. It's a German firm that owns a subsidiary called Graphit Kropfmühl, which owns a lump graphite mine in Sri Lanka. The asset produces about 3 Kt of the 5 Kt estimated world production. The rest comes from a private company owned by the Sri Lankan government.
TMR: Each electric car uses about 50 kilos of graphite and electric carmaker Tesla Motors Inc. (NASDAQ:TSLA) is proposing a battery-producing plant in the U.S. dubbed the Gigafactory. Graphite juniors are touting a potential boost in demand for graphite. Should investors believe the hype?
LM: By sourcing materials and building a Gigafactory in North America, Tesla is trying to lower the production costs and thus the price of its electric vehicles [EV]. But I don't think the Gigafactory is a done deal. Investors should closely follow what's going on with Tesla and understand its business. Standard & Poor's recently rated Tesla's credit as "junk" and that could certainly affect its ability to raise funds. I don't think it will deter Tesla from going ahead with its Gigafactory. There will likely be some challenges, but the company seems determined to build the factory to lower its production costs and make its advanced electric cars more affordable.
TMR: What was your reaction when you read Tesla's Gigafactory news release?
LM: When I first read it I thought that it could potentially be a game-changer, not just for electric cars, but for the strategic materials sector, namely lithium, graphite, cobalt and other materials that might be used in the EV batteries.
TMR: Some experts believe it could be easier for Tesla to rely on synthetic graphite rather than natural graphite. What's your view?
LM: The two aspects that Tesla likely will be looking at are performance of the materials and cost. If natural graphite can compete with synthetic graphite on cost and performance in lithium-ion batteries, I think natural graphite has a good chance to secure a position in Tesla's supply chain.
TMR: We should note that you don't cover any graphite companies but that you may at some point. Lithium is also used in EV batteries. Could this factory also possibly change the economic outcome of certain companies in the lithium space?
LM: Certainly. EVs use more lithium and more graphite than hybrids. If we see a greater adoption of EVs, we would definitely see an increase in demand for lithium carbonate and lithium hydroxide-the lithium products that go into these batteries.
Our forecast for lithium is based on the sales of hybrid vehicles only, which could reach 3.8 million [3.8M] per year by 2020 versus less than 2M now.
Current estimated annual lithium demand is roughly 170-180 Kt. If EV adoption rates meet projections, estimates suggest that demand could go north of 250 Kt by 2020. That is a significant increase and it will offer the opportunity for new projects to be developed.
TMR: How many EVs are currently being produced?
LM: Industry estimates indicate that there are currently over 400,000 EVs on the road, compared to about 100,000 EVs in 2012. It seems that EV sales have doubled every year for the last three years and if this trend continues, over 1 million EVs may be on the road in three years.
TMR: Is having the second-highest grade deposit in the world enough to get a small modular plant built near James Bay in Québec?
LM: The grade alone wouldn't do it, but the fact that there is a sizeable deposit close to good infrastructure-hydropower, road access-and a positive feasibility study, means it could potentially build an economically competitive lithium mine and plant in Quebec.
TMR: In a June research update you listed four rare earth elements [REE] companies that recently arranged financings. These financings occurred at near record low share prices. One even offered a half a warrant with its deal. Is this simply life in the rare earths space right now or poor management?
LM: I think it's life in the mining space. If we look at the performance of most mining companies, especially the juniors, they've been struggling for a while. The REE juniors are no exception. Companies with projects that only have a preliminary economic assessment or prefeasibility study and require $15-25M or more to reach the feasibility stage are finding it difficult to raise funds.
TMR: Are there signs the REE market could improve sooner rather than later?
LM: According to global economic estimates, we should see an increase in economic growth in the West, as well as in China, through the next couple of years. If we see that, I think that will be good news for REEs, as well as other critical metals. There could be a little light at the end of the tunnel here.
TMR: Some recent reports suggest that China may replace REE quotas with taxes. Please tell us more about the potential impact on the market.
LM: The World Trade Organization [WTO] ruled against China and its use of quotas. If China decides to comply with the recommendations of the WTO, I think that increasing taxes on REE exports or adopting tariffs would be effective ways China could still impose its policies.
China is determined to use rare earths resources to benefit its economy. China was supplying more than 90% of the world's REEs but only has about 36% of the world's resources.
TMR: Do you see the Gigafactory having any impact on REE demand?
LM: It is likely, as electrified vehicles use larger quantities of rare earth elements in magnets for their electric motors and in their more complex automotive systems.
TMR: A recent research report suggests that REE demand will grow at 6-10% annually through 2020. What accounts for that growth?
LM: It appears that some end-users are still using the stockpile material that they accumulated in 2011. Once those stockpiles diminish further we will see more end-users coming back to the market.
The other part of that is the normal growth in the economy. Demand for electronic products-cell phones, tablets, etc.-is in double digits in emerging markets. If we see the economic growth that's expected in the West and an increase in demand from emerging markets, over the next six years we may see a significant increase in REE demand.
TMR: Roughly speaking, how many development-stage REE projects reaching production would that growth in demand support?
LM: It depends. Some projects have production targets of 3 Kt, others 20 Kt. There is definitely opportunity for a few projects. We might see the need for about 100 Kt of new REE supply by 2020 if the global economy improves in a sustainable fashion. Asia is going to take some of the new supply as the consumption of China relative to the rest of the world may not change. I believe we should continue to see China as the largest consumer, followed by Japan.
TMR: Can you get us up to date on what is happening in Alaska?
LM: The Alaskan state government has proposed a $144M bond that would help finance the development of the Bokan-Dotson Ridge REE project. I think it's unprecedented. We haven't before seen local support like this in Alaska. It shows that the Alaska government recognizes the project as strategic for the state and, likely, the U.S. The financing arrangement has been signed into law and is contingent upon the completion of a feasibility study for the Bokan project and positive due diligence by the Alaska Industrial Development and Export Authority [AIDEA].
TMR: Do you have some parting thoughts for critical metals investors?
LM: Over the previous five years or so industrial metals and minerals have been increasingly adopted for use in advanced technologies. For instance, europium and thulium are used in LCD screens. High purity alumina and some rare earths are used in LED lights, which are replacing less efficient incandescent lights. Some rare earths are used to make magnets that go into motors. And these metals are being used to create even lighter strong metals. For instance, scandium and aluminum alloys have strength similar to titanium with the lightness of aluminum. There are so many different applications, but essentially these strategic materials are being used to improve our technologies and they're here to stay.
