Past performance is no guarantee of future returns as they say, so whilst historical facts can be very useful they do not mean that those who chose to live in the past will always be right. Sometimes you need to look to the future.
Lynas sold around $31,000,000 worth of product last quarter and whilst there are no guarantees, their production rates have significantly increased q on q and there is no reason not to believe that the trend will not continue.

Based on last quarter they are making the equivalent of $124,000,000 in sales per annum. Given increases in production and on spec production the drop in prices should be more than offset and whilst this May delay the point that the company becomes cash positive, ultimately they will get there IMO.
