The company website lists nine analysts that follow the project as well as their emails. Expect to pay for good advice. The other kind is free.When you ask for the "gold yield" you are showing your virginity. The yield will be about 92 to 94 % of the contained gold.......but I suspect that what you want is the annual production rate expressed in ounces per year.....but that is not what you asked.......further the annual rate will arise from a complete feasibility study not yet done.There are short courses in mining lingo and technical terms available. You might wish to google some.Good luck.........Oete.
