Thank you for the explanation of how you conduct business and answering my questions.


Question 1:The range in pricing for the hard drive boards is because the range in types. EXAMPLE: average scuzzi drive board contains around 250ppm of Au where as your average sata drive board contains around 100ppm of Au.

I have follow up questions regarding hard drives. You list the ppm(parts per million ?) of Au(gold) in two types of boards. What about IDE hard drive boards and what is the pricing for each type of board? Could you also explain how or where those yield numbers come from and also what is the ppm of the other metals found in those boards?



Also what does 100 ppm of Au(gold) translate to grams?
