Video: Junior market dominated by ‘the lame, the halt and the blind,’ says Rule
Over two-thirds of today’s junior miners are essentially worthless, says resource speculator Rick Rule.

Lithium batteries have a variety of blends that entail many improvements and trade-offs.
The EV industry developed the NMC mix, which has less cobalt than lithium-cobalt-oxide batteries (LCO), commonly used in the portable electronic industry.
NMC chemistry is evolving with a shift from the relatively cobalt-rich NMC111 to the NMC811 cathode configuration, partly driven by the higher energy density of the 811. An even bigger factor in the move to the 811 configuration is the limited cobalt supply.According to the United States Geological Survey (USGS) approximately 123 KT of cobalt was mined in 2016, and the organization projects insufficient supply to meet demand in 2017.

At present, approximately 30 percent of annual cobalt use is in a variety of technical applications, including material used for EV batteries. This segment is expected to increase rapidly, with demand likely outstripping supply. The result has been a rapid price increase, from USD 20,000 per metric ton tin January 2016 to over USD 60,0000 per metric ton in September 2017.

Constraint in supply are likely to persist. Approximately 60 percent of cobalt production comes from the Democratic Republic of the Congo, which present both operating and reputation risks from mining companies. Additionally, cobalt is rarely found in high concentrations and is mostly produced as a byproduct of copper and nickel. Limited new investment in these two commodities and only increase supply challenge for cobalt.
Consequently, cobalt supply constraints are likely to curb the growth of cobalt rich battery technology, including NCAS and NCM. For now, manufacturers of these high capacity batteries are trying to reduce the percentage of cobalt content by increasing the amount of nickel sulfate used. For example, the 622 battery (two parts cobalt per six parts nickel) used in a number of European EV battery application may be replaced soon by an 811 chemistry with only one part cobalt and eight parts nickel.
