"the plant has yet to recover significant quantities of uranium, contrary to expectations.
The cause for this is uncertain"

Is this a small hiccup, or do we have something a little more material we need to worry about here?

Terrible wording. I may try calling up tomorrow to seek greater clarification on this.

Hopefully the share price holds together tomorrow.

Interestingly the progress report came late in the day with trading re-commencing at 3.55pm.

Good luck to holders. Hopefully it is just a small hiccup.
