As stated previously, fluctuations of 1/10,000th or 2/10,000ths of a cent do not constitute a "plunge" any more than they would represent a "spike."
Waiting for a suitable period of time to get all the information back from all 5 dredges is not "ignoring" investor fears as mistated below:
"SGCP PPS plunges! Mining company is Ignoring investor fears and not releasing production numbers. WORD IS THAT ONE SENIOR MANAGEMENT MEMBER LEFT the usa to africa."
Interestingly, since the company has operations if Africa, it should come as no great revelation or shock if a "SENIOR MANAGEMENT MEMBER goes over there" OMG! LMFAO!!
Correction: Doug lives in Canada, so he left from Canada to Africa, not the USA to Africa as was also incorrectly stated.
When considering the reliability of any information one must consider the reliability of the source.
