Luzar - Neglected Mine response to questions letter dated January 7, 2009 Page 2 <br />An example for a typical 50# batch of ore is as follows. This process does not specify <br />times, mixing methods or minor adjustments that are necessary to maintain the correct RedOx <br />potentials, just the amount of each material as used and is based on the initial run. The quantities <br />would vary a bit based on the specific ore type processed. <br />Extraction step <br />• Ground ore - 50 # <br />• Water - 12.5 gallons <br />• Sodium Bromide - 1 # <br />• Sodium Chloride - 2 # <br />• Potassium mono-persulfate - 0.6 ounces <br />• Filtered to remove solids <br />Precipitation step <br />• Precipitation Solution - 3.1 oz of solution containing 20% Sodium Hydroxide [0.62 ounces <br />NaOH added to 3 ounces of water] to which is added Sodium Borohydride to make a 6% <br />solution [0.18 ounces NaBH4 added to 3.1 ounces of Sodium Hydroxide solution]. <br />The information seen above indicates that the spill of any single batch would involve a very small <br />quantity of process chemicals. The clean-up of an entire 50# spill could be handled with 1/4 to'/2 <br />bag of "Universal Sorbent - Bulk" available from any chemical house. The neutralized material <br />can then be disposed of in a Subchapter D landfill, such as the Bondad Colorado Landfill. <br />If you have any other questions or would like me to provide additional information please <br />give me a call, <br /> <br />Joe Bowden Ph.D. <br />Senior Scientist & Partner
