All small miners have to raise capital from time to time to do their drilling.The more the SP falls the greater the dilution. If you are selling completely or thereabouts and come in for the lower price you have done well (provided they make a good strike after the CR and before the following CR). If there is a good strike from the current drilling program you do badly because the SP will rise significantly. It is a little surprising that with TRT drilling areas known to have good potential (from previous exploration) the SP has fallen so much.
BUT yes, the shares will be cheaper if there is a CR before any decent strike.
