I was made to understand that there are over 10 gold mining/producing countries of the world namely, China, Australia, United States of America, Russia, South Africa, Peru, Ghana and Canada. It was written 244,000 metric tons of gold was said to have been discovered of which these figures was said to have been gotten from only 3 countries just like it's written in the image below which  i got from Google search. So my question now is, how about the rest 7 countries, was no gold discovered from there?
