I think JPMorgan shut their resource fund down and sold out of all positions (slowly but surely) including Danakali
It's also the reason that Neil Gregson (who headed up the JPM resource fund) stepped down in January 2020

Note that the first job he took (post a 30 year career in the City of London as a highly regarded fund manager) was a board seat with Danakali and is their sole UK director in charge of the London LSE listing

Credit Suisse?

Maybe you mean The Capital Group that held stock in DNK?
This is a longer story, but briefly, the head of this fund was up to no good so was fired
All positions in that fund were sold off as well
When DNK were 75 - 80c, their stock was sold to a mysterious buyer at 57c
It is now held in a UBS nominee account and selling continues
