RE:Possibilities...Here is some math for you.
After the PEA was released by the company (2/16/2021) Frontier had a total market cap that settled in at about 14% of the $974 million NPV value in the PEA. If I assume the NPV in the PFS is at the same discount to the life-of-mine as in the PEA then the new NPV should be $24.96 billion. Applying the same total market cap to NPV (14%) and then dividing by the current shares outstanding gets you a per share value of $17.02. However, the PFS will likely use a lower, "more conservative" price for lithium so the PFS and therefore show a lower NPV that in my calculation, which was done in the PEA. Let's say they use a price for lithuium that is half the current price, then the shares should be trading at about half my calcuation or $8.50 when the PFS is released. This is back of the envelop math, so there may be other factors that will affect the NPV in the PFS. Also, progress on other fronts are gradually de-risking the project and should reduce the discount to NPV implying a slightly higher price.
So, the long and the short of it is that the shares should be trading at about $8.50 after the PFS is released.
