•Secondary deposits typically contain a much higher proportion of high value (gem quality) rubies compared to primary deposits
•Mustang currently targets only secondary deposits as a source of high value gem quality rubies

This is taken from the recent presentation. The crucial question is in a Montepuez secondary ruby deposit what % is gem quality? From that we can work an average price and then the remainder the much lower price for non gem rubies. Is it 20/80 or 50/50, does anyone know have tried to find out? Thanks
