Gary,

""Oh by the way Tim to process a ton of ore using cyanide as the solution itself is 60.00+ compared to an average price of $8.00 with HGP solution.""

I am trying to help you understand mining, milling and associated technology. Are you reading aything that I am sending you.

Most large commercial gold mine using cyanide heap leaching technology have ore grades of .02 to .05 Oz per ton. This means that at $250/ ounce and assuming 100% recovery, that the ore is worth $5 to $12.5 per ton. I don't think any company is going to put $60 dollars worth of cyanide solution on a ton of ore worth 5 to 12 dollars. You better go back and check your source on this one.

Tim
