I was talking about the ore processing only, I'm uncertain regarding gold mining. I know Mexico is lower than most countries in mining costs, and surface mining would be even less per ounce. I'm guessing $500-$700/ounce.
they conservatively expect to generate $50,000 in gold from a ton of ore. costs mentioned - processing about $2500 --- they also mentioned trucking costs --- but i don't know if that was re: shipping from mexico to palm springs --- it was $3700. so costs to process a ton of ore is $2500 or $6000 --- and $50,000 in gold is produced (on average obviously - i'm sure some ore is richer than other ore.)
THIS DOES NOT TAKE INTO ACCOUNT MINING COSTS --- BUT THAT HAS NOTHING TO DO WITH THE PLASMA PROCESSING PLANT COSTS .... THOSE COSTS ARE EATEN BY THE MINING COMPANY
