i actually disagree... it is not about hardrock or brine its...

Would it be better to make a comparison to another brine producer such as ORE and not a hard rock producer.
KDR has nothing in common with LPI, its like comparing wine and beer.

i actually disagree... it is not about hardrock or brine its about what customer want i.e. quality & quantity of lithium (to produce batteries)... company valuations are not based on hardrock or brine they are based on quality, quantity & reliability of lithium produced... as an e.g. consumers don't care if electricity they get is produced through hydro, wind, electric, solar etc (coal diff argument) till its cost effective and reliable, same goes with commodities. 

One can differentiate btw h/rock and brine from a backend costing, capex, opex, reliability etc prospective but all that is taken into valuation of a business anyway...
