WFE (soon to be renamed Pathfinder Resources Limited) Prospectus, page-222

From my understanding in short NO.
You need to show where the shares went to
Ie sold /transferred before you can claim a loss.
Your shares are still there.
Your shares were delisted only and handed back to WFE .
The company then renamed itself Pathfinder.
Have you received your new Pathfinder share statement?
So then Pathfinder had a 200 to 1 consolidation so now you will have 1,000,000 ÷ 200 = 5000 Pathfinder shares.
So now the only way for you to claim a loss is to sell your new Pathfinder shares or I understand you can contact other parties ie (Google this) and dispose of them thru these parties.
But best option is to contact Pathfinder managment frist.
This is not Financial advise and is all in my opinion.
