Could happen any way, but in the past Crystallex issued a press release and there was no "leak." Hugo may want to make it a big deal at a ceremony this time, so it is possible that the VZ government could announce the issuance.

IMO it is unlikely that you will hear about it from Reuters or Bloomberg unless they are reporting the press release from the company.

Could be intraday, which would cause a halt, or could be pre or post market -- impossible to say at this point.
