Kev personally, I don't use the Lithium spot price as a barometer for the health of this investment. I use the Global exchange traded funds.
The Global X Lithium & Battery Tech ETF (LIT) invests in the full lithium cycle, from mining and refining the metal, through battery production.
It reveals activity in what I believe is the professional tier of investing and reflects the spot price, actual supply and demand, shorters, insular valuations - which account for offtake agreements (not based on spot price), retail sales of lithium reliant technologies etc.
It's only my strategy, not advice or suggestion to follow, yet you might like to keep an eye on it. I think you've done well and a recovery for you is already fairly certain from my analysis. Right now I value INR in the mid 30's to low 40's

Then post-DFS announcement we could see that price develop.
This is a prediction, so take it with the amount of salt that is necessary - I have a suspician that INR will surprise with it's deadline for the DFS and that it could come a month early. Take a look at my post today on
