I know of no permits in place to mine or process raw ore. In the works is all I know.
And just IMHO, we would not process antimony. We'd dig it out, separate out of the raw ore the gold and antimony in a gravity sep process, then send the separated antimony to a third party to process it. The processing required would be minimal since the antimony is so pure with very low arsenic concentrations. We'd not get $3.06 per lb for finished Sb, no mine would. But since ours is so pure, we'd get a substantial chunk of that price.
And of course we'd then process the gold.
