Or over 950 artifacts have been recovered but only a single coin? That is, in fact, the "first PR, is it not?
Nope.
The first PR will be worldwide and it will not be written by SFRX on a Facebook post. It will be done by a marketing company/attorneys published according to SEC guidelines.
Have you heard of the SEC ...You probably don't since the company you work for does not report to them.
If the material value of a reporting company is changed the company has to notify the shareholders by a published press release within 3 business days.
One silver coin and apparently 950 artifacts does not change the value of SFRX so it was just considered an update.
