6)Mr Green in his podcast of 4 Mar 2019 said Kiran, CEO of KDNC expects a "supply squeeze". This is known in the industry itself. However, Mr Green pointed out about "quality" projects. By quality, it was not explained so what exactly would quality mean? As far as I am aware, Australian lithium especially without mica etc ie at Bald Hill, near KDNC*s Picasso may be considered quality per their CEO?

Quality could mean many different things. e.g. attractive NPV, IRR, payback times, jurisdiction, infrastructure, etc. In the lithium world it can also refer to the quality of the product - the chemical composition. For lithium products it isn't so much the percentage concentrations that the suppliers are interested in (though this is important!) rather the contained percentage impurities, especially impurities that can cause adverse chemical reactions in the end products (batteries).
Take a look at:

Li2CO3 of 99.5% purity – Standard battery grade Lithium Carbonate
Li2CO3 of 99.9% purity – Enhanced grade Lithium Carbonate for xEV use
Li2CO3 of 99.99%, 99.995% and 99.999% purity – Superior grade Lithium Carbonate for xEV and special applications
]===
Other definitions are available. 99.5% seems to be a common threshold for "battery grade", but as I mentioned above not all 99.5% grades are equal, and is one of the oft stated reasons why Lithium is hard to commoditise, that and its relatively short shelf life in comparison to other metals, due to its reactivity.
Put another way, a 99.5% product from one mine that is sourced by a cathode supplier can't be interchanged with a 99.5% product from a different mine without substantial testing beforehand, unless the supplier is confident the composition is practically identical - which is certainly not going to be the case between the different Lithium sources: brines, hard-rocks, clays, and to a large degree within the same source too if geographically separated and/or processed differently.
