The same people berating the company for delays would have been quick to point out the double folly of April Fools Day and the last trading day before the long weekend.
However if the company is unable to release the Resource estimation early in the next week I would see it as appropriate that some comment on the delay is forthcoming.
There are likely some Stock Exchange hoops that have to be jumped through once the actual documention is received which could well add a couple of days to the process.
