As an attorney who focuses on import and export laws I have worked with clients who have been approached online by Ghanaians at a dating website or other forum offering a chance to purchase gold. One must take a look at the totality of circumstances in determining whether these are legitimate. More than a majority of these are scams in an effort to con persons into wiring money and never seeing a return. The U.S. Embassy has posted helpful information on this topic here: http://ghana.usembassy.gov/romance_scam.html.
If you have questions or concerns around the validity of potential gold offerings, speaking with an attorney who has handled these types of matters can save you from being scammed.
