Haven't seen a pause in trading 30 mins prior to close but also strategically on a Thursday for plenty of Friday action. Potentially glad I line wiped 22c today as my last chunk prior to what i thought was news events coming.. That is why (if this is good but even then during a period of "activity" it is better to just jump in).... and buy on market offer.
Not sure it definitely isn't 2:1 as that is statutory and not required for a pause and almost always not clarification or info around DFS already presented and didn't think they were putting much resource into this.
Typically ASX ask questions on the announcement that may have been flagged. So maybe drill / resource upgrade questions.... I think .. i think it will be extension of tailings life
