I find this site an easy reference to commodity prices and global data
https://www.theglobaleconomy.com/world/phosphate_rock_prices/Note I have set it to Phosphate Rock prices - which have crashed in the last two months, probably due to high stock levels which were consumed over the holiday period (just my view, a bit like Li too!) -
however if you swap to Triple Super Phosphate or Diammonium Phosphate you will see the price to end users has held up on a yearly rise.
You get to Triple Super via a Phosphate Acid plant.
I hold AMN on the upcoming shortage of phosphate and fertiliser generally - and on their indirect part ownership of WA1 which is doing well.
I also hold ENR - for Nb, but not WA1 (???) - here are some maps.
Please note there are possibly errors, and certainly omissions. I do intend to review the AMN areas - but note the structures and basement geology entering the general area.
Please note this is not advice dyor, and GL.
1. Magnetics.
2. Magnetic Anomalies. 
3. Same Over Basement Geology.
4. Tenement Holders over part of West Arunta in West Australia.
