Funny enough, last time that happened share price dropped 10% before the announcement everyone thought bad news was out, turns out the next day it jumped back 10%. Also on the day of the most recent quarterly the share price was only trading at 5.3c (from 5.1c) it increased substantially in the afternoon to close the day at a high of 5.9 or 6c, don't remember exactly.
Ask Hotfire, he would probably have more accurate figures, i dont trade so i dont follow the numbers as closely.
