Thank you @Inzhaghi88 your response and the additional info is much appreciated, very interesting to hear. I was looking forward to your next post.

There's an additional interview with PB on the net in addition to the earlier one from TS that someone posted and I got the same impression from the interview that they are serious and in for the haul. He was talking about the slog that they have had to get the project to this point. From memory he referred to 3 - 5 years to get to DTM.

I'm also poised to buy a bit more once I see if it stabilises in the 5's.

Appreciate @Insiderunner's follow up post also.
