Not too sure and haven't looked into Jupiter too much but I'll guess:

1/ Energy issues, lack of power, expensive and unreliable power, blackouts etc that interrupt production
Possibly days without electricity at their mines

2/ Port constraints so they have to use alternative routes or alternative ports in neighbouring countries, more trucking, more km's and therefore all costs go up

And it's such a cut throat business and margins are so tight that it can turn ugly pretty quickly

I don't even know what their share price is so the above is me just guessing
