The Company is allowed time to digest and review the report, I do not believe there is any fixed time frame to release material news. But insiders would be under a blackout for buying/selling from the time they received the report until it was released.
GI have never worked for a mining company but I can't imagine that the results of the PEA are not already pretty much known to insiders. They have obviously provided RPA with all the data and guys like Stowe would know and build up the mining and processing costs.
It may even take a full day or a few days to write the summary news release and have it approved.
As a general rule of owning a junior mining stock one does not usually like to see Trading Halted, but in this case I am begging for it..lol
