To open pit mine with the leaching method will require more than most expect. Phgi will need a crusher to reduce the rock and ore that is of value to 3/4 of an inch. Earthmoving equipment to bring ore to the crusher and then to spread across the leaching field. They will need a filter system to seperate the metals from the acid. Recycling the acid and beganing the smelting.This process will require a building to house the processing/smelting equipment. The leaching field will also take up more of that five acres. Off site leaching field and processing would require more trucks, earthmovering equipment,fuel,time, and labor. All of this on BLM land pretty impressive. This is probably the best method but with out a full scale mining permit and more cash from a hemorrhaging. Pray that JB will focus on the biofuel, that is the real gold mine.
