We are following Richard Mills on this blog and he has written another very insightful article on the Brine Mining and - what we call Investment For Life - Potash and Lithium. Richard provides a very deep knowledge of the industry, but can tell the story very efficiently in a straight forward language giving the necessary focus points for the investment decisions. His ability to spot the future trends and companies making it gives him a wide following among junior mining community.
Richard Mills follows a number of companies involved in Lithium and Potash Brine Mining and developing, you can find them on his website with another great articles. Recently he has wrote a piece on International Lithium - we are following here and our Top Pick in the sector; and he was one of the first letter writers to write about Lithium juniors in 2009 including TNR Gold - our Top Pick in Rare Earths, Gold and Copper, Rodinia Lithium - our another Lithium play, Western Lithium, Lithium One and Canada Lithium among others. His Lithium ABC became a classic in this investment sector.
ILC currently holds nine highly prospective projects for lithium and rare metals. One of the more prospective lithium properties in ILC’s property portfolio is the Mariana lithium brine project in the mining friendly province of Salta, Argentina.
The Mariana Lithium Brine project is on the Puna plateau which sits at an elevation of 4,000m, stretches for 1800 km along the Central Andes and attains a width of 350–400 km. The Puna covers a portion of Argentina, Chile and Bolivia and hosts an estimated 70 - 80% of global lithium brine reserves."
Please, do not forget, that we own stocks we are writing about and have position in these companies. We are not providing any investment advise on this blog and there is no solicitation to buy or sell any particular company here. Always consult with your qualified financial adviser before making any investment decisions.

The Puna plateau sits at an elevation of 4,000m, stretches for 1800 km along the Central Andes and attains a width of 350–400 km. The Puna covers a portion of Argentina, Chile and Bolivia and hosts an estimated 70 - 80% of global lithium brine reserves.
The evaporate mineral deposits on the plateau - which may contain potash, lithium and boron - are formed by intense evaporation under hot, dry and windy conditions in an endorheic basin - endorheic basins are closed drainage basins that retain water and allow no outflow - precipitation and inflow water from the surrounding mountains only leaves the system by evaporation and seepage. The surface of such a basin is typically occupied by a salt lake or salt pan. Most of these salt lakes - called salars - contain brines which are capable of providing more than one potentially economic product.
This Puna Plateau area of the Andean mountains - where the borders of Argentina, Bolivia and Chile meet and bounded by the Salar de Atacama, the Salar de Uyuni and the Salar de Hombre Muerto - is often referred to as the Lithium Triangle and the three countries mentioned are the Lithium ABC’s.
Brine “Mining”
The salt rich brines are pumped from beneath the crust that’s on the salar and fed into a series of large, shallow ponds. Initial 200 to +1,000 parts per million (ppm) lithium brine solution is concentrated by solar evaporation and wind up to 6,000 ppm lithium after 18 - 24 months.
The extraction process is low cost/high margin and battery grade lithium carbonate can be extracted.

The above diagram was designed to show that several commercial products can be recovered from typical brine and that the recovery takes place in a series of steps over the entire evaporation process. Note that the final product in each step may require processing in a specialized plant. Also please note that the actual sequence of process steps may vary from brine to brine, and as such, the process steps shown above may not be in the correct order for any specific brine.
The key factors that determine the quality, economics and attractiveness of brines are:
- Potassium content
- Lithium content
- Presence of contaminants ie magnesium (Mg)
- Porosity
- Net evaporation rate
- Recoverable by-products
- Infrastructure – or lack thereof
- Country risk
- 100% control over production
- Low capex, low production costs, high margin products
A common industry axiom says that the ratio of Mg to Li in brines must be below the range of 9:1 or 10:1 to be economical. This is because the Mg has to be removed by adding slaked lime to the brine - the slaked lime reacts with the magnesium salts and removes them from the water.
The porosity of a rock is expressed as a percentage and refers to that portion of the rock that is void space - rock that is composed of perfectly round and equal sized grains will have a porosity of 45%. Fluids and gases will be found in the void spaces within the rock.
Ten million cubic meters of brine bearing rock with a porosity of 10% will contain one million cubic meters of brine fluid. A cubic meter is equivalent to a kiloliter.
By oil and gas standards a porosity of 10% is quite low, but brines are less viscous than hydrocarbon fluids and will flow more easily through rocks with lower porosity and permeability characteristics.
A major factor affecting capital costs is the net evaporation rate – this determines the area of the evaporation ponds necessary to increase the grade of the plant feed. These evaporation ponds can be a major capital cost. The Salar de Atacama has higher evaporation rates (3200 mm pan evaporation rate per year (py) and <15 mm py of precipitation) than other salt plains in the world and evaporation takes place all year long.
Contributing to efficient solar evaporation and concentration of the Puna Plateau brines are:

A company should have 100% control over the production rate from their salar. It’s possible an aquifer can become diluted - over producing can impact the brine’s salt concentrations and chemical compositions - or depleted by too many wells sucking up more brine than should be produced.
If two or more companies have straws (wells) into the same salar legal battles might result over the sharing of the resources.

Potash is Fuel for Food
Potash is used as a major agricultural component in 150 countries but the largest importers of potash are China, India, the US and Brazil.
Potassium sulfate is commonly used in fertilizers, providing both potassium and sulfur. Potash is the common name for potassium chloride.
The basic fundamentals of the global potash market are hard to ignore:

The basic fundamentals of the global potash market are hard to ignore:
- An increasing global population - the world's population is steadily increasing and is expected to reach +9 billion people by 2050. The United Nations Food and Agriculture Organization (FAO) reported they think that the total world demand for agricultural products will be 60 percent higher in 2030 than it is today.
- Increasing incomes in developing countries will lead to more people being able to afford protein rich diets – a western style diet heavy in meat - which means more grain consumption.
- Decreasing arable land - arable land is being lost at the rate of about 40,000 square miles per year. Land is being used for production of bio-fuels, topsoil is eroded away by wind and water and the agriculture land base is being paved over as we become more and more urbanized. Farmers need to produce more food on less land. There is only one way this can be done and that’s with an increase in the use of fertilizer.
The current potash market is estimated at 50 million tonnes annually and is projected to grow at a compounded annual rate of 3-4%. Potash is a crucial element in fertilizer and has no commercial substitute.
Lithium
The world’s future energy course is being charted today because of the ramifications of peak oil and a need to reduce our carbon footprints.
A whole new industry - a global wide automotive and industrial lithium-ion battery industry - is being built. As a result of lithium-ion battery demand for hybrid-electric and electric cars the increase in demand for lithium carbonate is expected to increase four-fold by 2017.
Lithium-ion batteries have become the rechargeable battery of choice in cell phones, computers, hybrid-electric cars and electric cars. Chrysler, Dodge, Ford, GM, Mercedes-Benz, Mitsubishi, Nissan, Saturn, Tesla and Toyota have all announced plans to build lithium-ion battery powered cars.
Lithium carbonate is also an important industrial chemical:

Lithium carbonate is also an important industrial chemical:
- It forms low-melting fluxes with silica and other materials
- Glasses derived from lithium carbonate are useful in ovenware
- Cement sets more rapidly when prepared with lithium carbonate, and is useful for tile adhesives
- When added to aluminum trifluoride, it forms LiF which gives a superior electrolyte for the processing of aluminum
- Lithium carbonate can be used in a type of carbon dioxide sensor.
Lithium is not traded publicly - and is usually distributed in a chemical form such as lithium carbonate (Li2CO3) - instead it’s sold directly to end users for a negotiated price per tonne of Lithium carbonate (Li2CO3).
Production figures are often quoted in lithium carbonate equivalent quantities. By weight approximately 18.8% of lithium carbonate is lithium. Therefore 1kg of lithium is the equivalent of 5.3 kg of lithium carbonate.
Lithium-ion batteries are quickly becoming the most prevalent type of battery used in everything from laptops to cell phones to hybrid and fully electric cars to short term power storage devices for wind and solar generated power.
Sodium Chloride (rock salt or halite)
The principal use for salt is in the chemical manufacturing business - chloralkali and synthetic soda ash producers use salt as their primary raw material.
Salt is used in many applications and almost every industry:

Salt is used in many applications and almost every industry:
- Cooking
- Manufacturing pulp and paper
- Setting dyes in textiles and fabric
- Producing soaps, detergents, and other bath products
- Major source of industrial chlorine and sodium hydroxide
Global demand for salt is forecast to grow 2.5 percent per year to 305 million metric tons in 2013.
Solar evaporation is the most popular and most economical method of producing salt. China is the world’s largest consumer of salt – other than the dietary needs of 1.3 billion people - there’s an enormous chemical manufacturing industry being built in China.
Boron
Boron combines with oxygen and other elements to form boric acid, or inorganic salts called borates.
Borates are used for:

Boron
Boron combines with oxygen and other elements to form boric acid, or inorganic salts called borates.
Borates are used for:
- Insulation fiberglass
- Textile fiberglass
- Heat-resistant glass
- Detergents, soaps and personal care products
- Ceramic and enamel frits and glazes
- Ceramic tile bodies
- Agricultural micronutrients
- Wood treatments
- Polymer additives
- Pest control products
- Boron is an essential component in the manufacture of borosilicate glass used in LCD screens
Boric Acid uses:
- As an antiseptic/anti-bacterial compound
- Insecticide
- Flame retardant
- In nuclear power plants to control the fission rate of uranium*
- As a precursor of other chemical compounds
*Boric acid is used in nuclear power plants to slow down the rate at which fission occurs. Boron is also dissolved into the spent fuel cooling pools containing used fuel rods. Natural boron is 20% boron-10 which can absorb a lot of neutrons. When you add boric acid to the reactor coolant – or to the spent fuel rod cooling pools - the probability of fission is reduced.
World production of borates remains mostly concentrated in the US and Turkey – these two countries account for 75% of supply.
Chinese boron - both in terms of quantity and grade - is inadequate to meet domestic demand so the country is now the largest importer of both natural borates and boric acid.

Conclusion
Potash and agriculture will be one of the top investment themes over the next 20 to 30 years - world population growth and three billion people climbing the protein ladder are elephants in the dining room. Our population has nearly doubled since 1970. We add 80 million people to our global population each year - tonight, there will be 220,000 new mouths to feed at the dinner table.
The rechargeable power needs of our modern society has made lithium a serious player in the commodity markets. Lithium makes an excellent battery for use in a wide range of applications - batteries using lithium have been found to have a high energy to weight ratio, can be moulded into amazing shapes and have longer lives than conventional batteries.
And when used as a rechargeable battery there is no memory effect.
There are significant savings to be had in the pricing of lithium from brines for lithium miners with quality projects close to all necessary infrastructure.
Investing in a macro trend has always been the most dependable way to make money - rising food prices are a macro trend with a long term time horizon, so is the electrification of our transportation system.
Are both these global macro trends on your radar screen?
If not, maybe they should be.
