RE:Why Else Did TTX Not Release Information…Yes and no ... they did manage to report the export of the tin and tin is also included as a "conflict mineral". Having said that I can't think of why else they would hide this info other than some unlikely and dismal possibilities like ... they misrepresented the presence of Ta in the first place, which makes no sense or, the Ta numbers were so bad they feared they would look like inept dumbassses?
Keep in mind this is a "deposit" that they either forgot to drill off before digging up or they did drill but the numbers sucked so they failed to disclose them to the public, and for some reason they went ahead with it anyway?????????? Who knows?
No idea and nobody will know for sure until they finally, belatedly, disclose what happened to the missing Ta
