Stirred resin for 5 minutes then poured into another container and stirred for another 5 minutes.
Added a glasscast blue pigment and stirred for another couple of minutes to blend.
Done a 2mm pour and torched out bubbles but have observed this anomaly in a section of the pour.
Can someone tell me what’s going on here please?

It's hard to tell from the picture but it looks like a wisp of resin which the pigment has not quite mixed, perhaps the edge of the bucket  

Any further pictures?

The pink colour is backing for a plastic sheet. Not a pigment. The pigment I used was a glasscast blue but gone extremely light with the colour.
How long should you mix the pigment having done 2 x 5mins and poured from one container to another after 5 minutes?
Here’s another pic

I think it is rather a case of how you mixed and not for how long. make sure to scrape along the walls and the bottom of the container and use a suitable mixing pot without any plastic reinforcement fins in the bottom or anything like that...

5 minutes per bucket is typically about right.  Technique is also important ie care taken to mix the whole ingredients not just "stirring" it but folding from top to bottom, scraping sides and base to ensure it is evenly mixed throughout.

To my eye, that looks more like some other darker contaminant in the mixed resin...

I had that kind of problem with my mixing sticks  having been contaminated with pigment powder used for  dyes (still chasing the kids around for stealing from my bag of mixing sticks :-)
