Ann: Diamond Drilling confirms Thick High Grade Gold Zones, page-21

True, and you often see the SP rise after the raise.
The devil is in the detail however, which is only known after the CR is announced. Prior to a raise where people know one is surely coming the thinking will be: how many shares will be issued, at what price, will there be oppies, can retail holders participate, what are the funds to be used for etc.
If the raise is done on to a broker at a cut-rate price with no retail participation, or just the sophisticated & professional crowd getting a look in, it will cause wailing & gnashing on teeth as these operators have a track record of dumping their shares in large part for whatever profit they can make in the short term, which can hold the SP down for a frustratingly long period of time.
People are always wary of dilution & are seeking value - there are plenty of PM stocks on the ASX to choose from so people like to make informed decisions on where to place their hard-earned.
