trading halt, page-29

That is why I suspect there is more than just the PFS to be released in this announcement. The PFS document on its own has been available to the company for some time. They would have had ample time to prepare any associated literature to be released with the PFS document already and while they would still have gone into a trading halt due to the price sensative nature of the information in the PFS, the announcement would have been made within 20 minutes of going into trading halt.

If however they have more than just the PFS to announce (eg offtake agreement, JV or something similar) which had only just been finalised, they would require some time to prepare information to be preseneted to the market.

Just my thoughts, but I suspect if it was only PFS it would have been released today 20 minutes or sao after trading halt.
